Medical device industry to avoid the double squeeze of high boom continues
Take the bull market of the pharmaceutical industry for two years, this year can be described as difficult, the industry not only in the first quarter compared with last year\\ s revenue and net profit growth year on year downward trend, and industry index continued to fall at the same time, the pharmaceutical industry is also subject to price reduction policy and cost twofold increase in pressure, can be said that fatigue filling.
In contrast, there is no price crisis by medical device industry is Chunfengmanmian, new GMP implementation, which will help the medical device industry to upgrade the overall optimization; peak rural health care institution-building has not ended, the industry will continue the current high degree of prosperity .
Avoid upward pressure on drug prices and costs
\"medical equipment is the pharmaceutical industry since the early 2011\\ s touch of bright colors. Pharmaceutical industry in 2011 from January to April increased revenue growth in the main case, but the total profit growth rate dropped significantly, indicating that the current pharmaceutical industry is facing drug prices and the dual pressures of rising costs, profit margins were squeezed, while the medical devices sub-sector is not subject to price reduction as the impact of policies, continue to maintain a rapid growth of which, a quarterly medical device companies accumulated a total profit of 37.31% of the high-growth, ahead of other sub-sectors, the pharmaceutical industry to become one of the few bright spots. \"controversial for the pharmaceutical industry this year, Xiangcai from another angle to give medical device industry highly.
It is obvious that the reason why the medical device industry can continue to maintain this rapid growth, which they are lucky to avoid upward pressure on drug prices and costs are directly related.
The first half of this year, the pharmaceutical industry is suffering a wave of price cuts, which cut prices of essential drugs is already reflected in the provinces tender, and health insurance directory, anti-infective and circulatory system drugs price reduction policy has also been introduced, follow-up of prices of other categories of drugs policy another floor.
At the same time, traditional Chinese medicine this year, leaving tidal waves of price increases suffered much pharmaceutical companies. Guangzhou Pharmaceutical (15.00,0.07,0.47%) (600 332, closing price of 14.93 yuan) Deputy General Manager Pang Jianhui said the company will expand the GMP base, strengthen cooperation with Chinese herbal origin, centralized purchasing and other means to respond to price increases caused by Chinese herbal medicines impact.
Pharmaceutical industry is in \"dire straits\", but the medical device industry has no trouble. Currently, there are many favorable factors driving the rapid development of medical devices, which is the industry are more concerned about the reason.
Benefit from the aging of the population
In China, the medical device industry is still a new industry, whether production or research and development can not meet all the needs of the market. At present, China\\ s medical device and drug consumption less than 1:5, while in developed countries, this ratio has reached 1:1.
General Manager of Guangdong Nasdaq investment, private equity fund manager Lishi Yu said: \"China\\ s medical market is a rapidly growing market in the past 10 years, compound annual growth rate of 22%, the current market size of 100 billion yuan. Medical device market scale in the proportion of the entire pharmaceutical industry has grown from 8.8% in 2002 to upgrade to the current 12% to 15% in the United States, this ratio is about 35% in China to double this ratio means that there is room. \"
Industry sources say that the future growth of medical equipment, mainly to see the three major driving factors, namely health care system to expand coverage, improve capacity to pay of consumers, and government investment in primary health care system. However, the industry first needs help, or China\\ s aging population trend. At present, China has basically entered the aging early stages of direct expansion of the medical device industry, market demand for capacity.
Lishi Yu pointed out that \"studies have shown that, in 2007, China has gone through demographic change on behalf of the \\ Turning Point\\ , which means the speed of aging will be faster in China over 65 years the proportion of the total population in 1990 5.6% 2010 9.3% 2025 and 2050, this proportion will reach 12.6% and 19.6%, according to Shanghai Research Center on Aging data show that population aging will lead to growth of total health costs rate 1.54%. \"
Demand the release of primary health care sector
The reason why there is a huge medical device development, in addition to the direct stimulation of an aging population, the national policy to support efforts to increase, but also provides a good opportunity for development.
Xiangcai Securities believes that the new medical reform in 2011 as the last year of primary health care institution-building continues, but the focus will be the amount of shift quality construction.
Specific requirements of the Ministry of Health, to the end of 2011, each county (county-level cities) at least a secondary level reached the level of the county hospital, 1 to 3 hospitals to center township standards. Therefore, the county hospitals and township hospitals represented by the rural health institutions will face the full upgrade. Upgrade medical institutions in rural areas mainly in the medical device configuration standards. The estimated period of the new medical reform, hospital equipment each county will invest 5.23 million yuan, compared with 2004 to 2008 period does not exceed $ 1.5 million of medical equipment to enhance significantly the standard configuration.
Xiangcai Securities also pointed out that taking into account the start of 2009 to 2010 there are some medical institutions in rural areas are not completed, estimated in 2011 at least 845 county-level hospitals and township hospitals in 2635 will be built in the construction or condition. Accordingly, the potential of rural medical institutions for medical equipment needs more than $ 6.3 billion in cash is expected before the end of 2012, the medical equipment of high prosperity will continue.
Reporters also learned that the Ministry of Health published in the \"five key health system reform of 2011 the main work\", the support 300 so clearly on the county-level hospitals, 1,000 township health centers and so on more than 13,000 village health room building at the same time, the Ministry of Health also plans, by 2015 all county-level hospitals nationwide have reached the level of secondary level hospitals.
New GMP to accelerate industry consolidation
Policy support at the same time, the formal implementation of the new GMP this year, will also promote industry concentration, positive rapid development of leading enterprises.
New version of the high standards of GMP is mainly reflected in the cleanliness and software management, which is a sterile preparation of pharmaceutical dosage forms in the highest risk, including infusion, freeze-dried powder and water injection, so dedicated a new GMP Sterile Pharmaceutical Appendix, which is the core level of cleanliness, which pharmaceutical companies and sterilization equipment, air purification systems and a higher requirement.
Qianshan medicine machine (30.420, -0.28, -0.91%) (300216, closing price of 30.70 yuan) securities on behalf of the \"Daily Economic News\" reporter, said: \"Medical equipment manufacturing industry is a national health sector was one of more stringent regulatory is high-tech industry, the introduction of new GMP will be eliminated within the industry do not meet the requirements of small and medium enterprises, technology companies will be the core of a larger development space. In addition, the new GMP implementation of a five-year transition period after , and the enterprises still have time to reinvent itself, which also benefit the entire medical device industry, optimization of the overall upgrade. \"
Insiders pointed out that the new GMP for purification, sterile than before a lot of other requirements, if the companies do not have similar equipment, will increase more investment, especially in the higher level of purification of freeze-dried product lines. This requires one, the future of the pharmaceutical equipment industry will be the formation of long-term good.
Focus on individual stocks

The company\\ s strategy is to take full advantage of the marketing channels in the cardiovascular department strengths, to create a wide range of product lines, a comprehensive high-end medical device companies.
Medical device industry put forward new demands precision cutting tools
Difficult to machine materials, the complex shape of the workpiece and the frequent small-volume production of professional medical equipment for the processing tool made very high demands.
Precision medical industry standard
Hole diameter tolerance is usually + /-0.005mm or so; the direction of tolerance is about + /-0.07mm (for 108mm) or so.
medical devices, such products and prosthetic graft in the successful surgery plays a very important role and can help surgeons achieve the best possible medical effects. Processing tool in the medical equipment largely determines the quality of medical devices. Tool in the manufacture of medical devices is the use of a wide range of diverse, large-scale equipment can be processed (such as computer tomography X-ray camera) case of more simple parts, and products for transplantation or for the repair of calvarial production or treatment of fractures of the workpiece is more challenging.
Custom composite tool program to save time and money
And companies in other industries, as companies in the medical industry is also facing increasing cost pressures. To a company based on the highly competitive international stage, it is necessary to produce high quality low cost products. Products for transplantation (usually from high alloy steel, titanium or titanium alloy), the special materials and complex geometry of the workpiece accuracy of the product presented a great challenge.
For some processing may be required before three standard tools, but now only need a complex tool, to a process instead of the previous three processes, saving time and costs. For example, the processing of 1500 parts, each piece save 2 minutes, you can save 50 hours of machine hours. The disadvantage of this complex program tool is not reflected in the general sample of the tool. Walter\\ s proposed \"CATexpress\" non-standard tool customization services, and different from conventional non-standard services, the delivery time can be reduced from the previous 6-8 weeks to 14 days. The service to a particular software program, based on when the user connects to the Internet and enter all information (such as the application of information or machine type), the system will output a record contains the necessary parameters of the order. After the company received the order, you can begin production within the shortest time required for non-standard tools.
Tool manufacture portable products
Indexable carbide inserts WSM10, WSM20 mainly used for multi-axis machine tools and WSM30. \"Tiger Blade\" Tiger-tec? Coating and ceramic substrate for the processing technology provides maximum stability, heat-resistant high-temperature Al2O3 coating with the greatest degree of hardness and wear resistance, in addition, a sharp cutting edge to ensure glitch-free products and non-BUE. Because titanium is a frequent process in the medical industry one of the materials, the new geometry of the NFT, NMT and NRT are for processing titanium. NFT for finishing, NMT for medium precision machining, NRT for roughing, these blades can be combined using a simple tool system, so that user.
Precision – a basic requirement
Tolerances in the micron range are common medical industry, choosing the right tool requires insight and experience. On the one hand, even if drilling holes also need to use lubricants to reduce friction, heat and reliably handle thin blade at the iron filings; the other hand, in the production of cutting-edge medical devices (no glitches), the need to use sharp and smooth operation cutting tools for high-quality surface. High-speed steel cutting tools are used or solid carbide drill bits.
As a standard, solid carbide tool in the diameter range of 0.3 ~ 20mm. Pratt tap and thread milling cutter is mainly used for machining titanium alloys, such as bone screws or hip joints, 1.6mm diameter thread mill can also be used to produce dental restoration products.
Healthcare industry is optimistic about the enthusiasm of investors in the IT industry is not sub-
According to the investment in the Group\\ s statistics: medical and health industry in 2010 received a total of 103 investment cases, the total investment of 1.858 billion U.S. dollars, investors are keen on the healthcare industry as much as the IT industry. Pharmaceutical industry because of its practicality, there are inherent with anti-cycle characteristics, is attracting more and more investors to join them, known as the \"eternal sunrise industry.\"
Recently, a new leader in medical and health industry summit forum announced the industry leader, cutting-edge industry and growth of the top ten list released, and health, medical, health, medicine, and health of the whole industry chain derived from a variety of economic models will be the most With the wealth of the investment value of each point of the proof.
According to the summit organizers, the new leader in the pharmaceutical industry and the National Federation of Chamber of Commerce and the Joint Central Television \"business angel\" part of the research activities carried out in the list of 29 representative companies from different segments However, the main investment areas with the current basic agreement, mainly in pharmaceutical manufacturing, medical services and health care direction.
Which, in the pharmaceutical manufacturing, the industry leader in this list of Tasly, revised Pharmaceutical, Yunnanbaiyao, science, etc. have grown to record holding the representation of national pharmaceutical brands. The company also maintained a high sustained growth, as sales have exceeded Kechuang holding 190 million, a compound annual sales growth rate of the three as high as 427%, while China\\ s growth has been runner-up of the revised Pharmaceutical hundred remain 125% increase. Revised Pharmaceutical Group Chairman Lai repair your speech at the summit, said the one hand, a long history of traditional Chinese medicine, which will help develop the other hand, traditional Chinese medicine more and more international recognition. China\\ s pharmaceutical enterprises can make use of the inherent advantages of our Chinese culture, to strengthen the pharmaceutical development and research work, so that the export of traditional Chinese medicine products towards more high-end direction.
It is worth mentioning that, in the healthcare industry is the most promising medical device. The industry leaders such as diving medicine, on with the relevant universities and research institutions to establish close cooperation between research, increase R & D investment, with independent research and development to enhance the capability of independent innovation to enhance competitiveness, to become the capital market after the listing darling.
In addition, the U.S. NASDAQ listed company Global Medical Holdings, a wholly owned subsidiary of Global Pharmaceutical Group Co., Ltd. Shandong, also made the list, a healthcare industry leader. The company set the wholesale pharmaceutical market sales, the core business has covered many areas of Shandong province and the rest of the country. The company is working to build a logistics distribution center by the level and composition of the regional distribution centers two large pharmaceutical distribution group, the future for the global pharmaceutical business in China\\ s pharmaceutical quality basic layout to lay on.
“Second five” off the medical device industry opportunities
.jpg "surgical supplies")
Despite the international financial environment there are many uncertain factors, but in the future for a long period of time, China\\ s economic development will continue to improve, at the national level to further promote the health reform and the establishment of increasingly sophisticated and wide coverage of basic medical security system will not change the determination .
Industry is not in a large proportion of the national economy, can only be considered a small industry, but for disease prevention, disease investigation, treatment and protect the health of the masses and the role of quality of life is very great . Since the beginning of this century, industry in China and the world\\ s attention and widespread attention because, should this is it.
In recent years, as China\\ s rapid economic development, industry is also developing rapidly, the growth rate significantly higher than the GDP growth rate of a mile. By 2010, according to the National Development and Reform Commission statistics, China\\ s GDP reached 114.3 billion yuan, increased 18.7% over the previous year. However, this conservative statistical bias, significantly lower than the actual data. According to customs statistics, China\\ s exports in 2010 to 147 billion U.S. dollars, an increase of 20%, exports to developed countries including Europe and America, including more than 200 countries and regions, and more than $ 7.6 billion that year the total imports higher 71 billion U.S. dollars, ie U.S. $ 7.1 billion surplus.
The crux is that the industrial structure
Just from these data, it seems the situation very beautiful, but people in large hospitals and see the key medical equipment imported from abroad are basically the status quo seems to be inconsistent. In fact, the above data and the current situation we see no conflict at all, the crux lies in the industrial structure.
Since reform and opening, China\\ s industry has achieved considerable progress, many products can meet the needs of domestic and foreign markets, but mainly in the low-end product market. In the high-end products, compared with developed countries, China is a clear gap there, and even some still in the blank. This structure created a status of considerable bulk, the total value of roughly two-thirds of domestic exports, while domestic and medium-sized hospital grade medical equipment required for the majority of imported products is the situation.
In addition, the medical model also contributed to irrational irrational industrial structure, an important reason. Medical model of unreasonable force the majority of patients a doctor have to go to the hospital, resulting in recent years has been criticized for \"difficult and expensive,\" difficult to be resolved, the product basically sold to hospitals, hospitals in the traditional medical model to meet the needs of the next, so the hospital\\ s purchase will affect manufacturers often develop initiative. Established in a country can benefit all the people, broad coverage of basic medical security system, do not break through the traditional medical model is absolutely impossible.
If the domestic industry can adapt and benefit people\\ s livelihood, health care reform direction, producing a series can be extended to communities and the families of high quality, low cost, easy to use product, and use of communication technology has been fully spread, the patient, community health center , district hospitals and central hospitals together into an effective network for out of this dilemma will play very effective role in promoting.
Force policy and capital have
In fact, China\\ s relevant government authorities and people of insight has long been aware of the problems in our industry, a few years ago by the Ministry of Science, Academy of Engineering Expert Group and other organizations to conduct special research, and the formation of a written opinion, reported to the State Council. It is reported that the State Department level, has made clear that, to support the development of our industry, in particular, requires focusing on the development of high-end medical equipment, changing the product structure is irrational state.
Since the proposed health care reform task, the Development and Reform Commission, Ministry of Science and Society also commissioned a survey related to research on how to adapt and promote the health reform issue to make recommendations accordingly. Until October 2010, the State Council made a \"State Council on the cultivation and development of strategic new industry decision\" seven strategic emerging industries will be incorporated into the third \"bio-industry,\" clearly states that \"speed up the advanced medical equipment, medical materials, biomedical engineering product development and industry and promote the large-scale development. \"
This document has been put into national strategic industry to nurture and promote new industries, at the national level shows the importance of this industry. In addition, relevant government departments from two years of support for the project point of view, has clearly been much greater than in the past.
This year marks the \"second five\" plan the first year, the state of the industry will support and foster a more planned and reflected. Soon to be released, \"\" second five \"Industrial Technology Development Plan\", will provide our industry a more powerful role in nurturing and support. This, undoubtedly, our industry has created an excellent opportunity for development.
Positioned as the industry at the national strategic policy support emerging industries and related guidance under the premise of many venture capital are very positive about the domestic industry, in which the search rich potential investment projects. This development and growth for the industry provides a very favorable financial conditions.
Opportunities for the future
Despite the international financial environment there are many uncertain factors, but in the future for a long period of time, China\\ s economic development will continue to improve, at the national level to further promote the health reform and the establishment of increasingly sophisticated and wide coverage of basic medical security system will not change the determination . Meanwhile, China\\ s huge population base and growing market demand, both for our industry to create a long-term positive environment. Entrepreneurs should firmly seize this rare opportunity for development, to redouble their efforts towards the adoption of a number of years of struggle, so that the level of development of our industry to a higher level, with greatly reduced the gap between the world\\ s advanced level. If properly managed, there are the bigger of China\\ s remarkable industrial scale possible.
The future, areas most likely to receive government support and private capital policies favor, should be the following three aspects of the product:
First, high technology, China is currently rely mainly on imports of high-end medical equipment. High-end medical equipment R & D and production capacity to establish and enhance the development of the industry and leading role, and change our basic dependence on imported high-end medical equipment, the passive situation. What if China can produce the product, the corresponding prices of imported products will soon naturally, which is conducive to China\\ s vast hospital, and can reduce the financial burden of health insurance and patients.
Second, with independent intellectual property rights, with a strong technical ingenuity and market competitiveness of products by the medical profession welcomed. According to the scientific development concept, the state vigorously promote independent innovation, intellectual property control, a fundamental change in product mix, so that technical content is not high, the lack of your own, and would waste resources, pollute the environment, mainly relying on China\\ s low labor costs and lower price of the product line will gradually lose their competitive edge, will not have good prospects.
Third, it helps to promote the implementation of China\\ s medical reform policies and the establishment of broad coverage of basic medical security system products. The advancement of medical reform policies, the establishment of health insurance system, of course, depend on government policies, inter-unit coordination, standards development and implementation, to a large extent dependent on the emergence and promotion of appropriate products for the majority of the terminal and the layer node has the right products to work in coordination to form an effective network, fundamentally change the traditional medical model. This is obviously strong government support and the support and insight to get private capital in the special favor.
Nuggets medical information
.jpg "Gouge stitches")
Healthcare information technology provider of electronic medical records front of the first capital of the spring harvest, and gradually spread to attract the hospital information system construction. Break the cocoon of the market, not only Kingdee, UF set off a new round of merger integration, Huawei has different troops broke into.
Through telemedicine, doctors successfully Xinjiang Shanghai implemented a surgical patient; PLA 309 hospital doctors, by logging iPad mobile workstation, Taking command of a sudden comatose patient with rescue; iPad Drchrono service provider of electronic medical records to obtain Since DST founder Yuri Milner, including Russia (Yuri Milner), including 65 million investment; One Medical Clinic with the U.S. chain of information technology to bring cost advantages and economies of scale, smooth five rounds of financing.
These seemingly unrelated to the appearance, but point to the same trend: the most difficult nut to health care information technology field, beginning to achieve loose situation. From a single class of medical IT service providers access to venture capital favored to grab the software Gangster cloud services, hospital care market intelligence, moving from the top three hospitals have upgraded working system, to the local government to promote the social integration of the various measures of medical information systems medical information of the parties involved become clear, the production chain are increasingly forming the upper and lower ring. As the market supply and demand in the gradual and effective docking, the hospital\\ s profit model is expected to improve, and in the local government\\ s boost, the software service providers will grow faster and open space.
Force first electronic medical records
The first step in medical information, the promotion of electronic medical records through electronic health records, not only the patient\\ s condition and the treatment itself effectively track record preservation, but also significantly reduce the workload of doctors and hospitals to facilitate the timely diagnosis. Value of information surrounding the development of electronic medical records, many stakeholders, including patients, clinicians, hospital administrators, community health, medical insurance, public health, health administrators, research institutions, are expected to benefit, and telemedicine, separated diagnostics and other areas of large-scale space applications or can be synchronized to achieve a breakthrough. In addition, the wider social benefits of electronic medical records is based on the format of a unified electronic medical record, the government can use information and business systems platform interoperability, data exchange and business collaboration, and dynamic management of the health of residents, \"Poison milk \"and other similar public health emergencies will be possible early in the outbreak was discovered through an early warning system.
In foreign markets, many independent start-up company is positioned as electronic medical records service provider. Because the entry point at the front of the medical information industry chain, earnings outlook is relatively clear, its capital is also an olive branch after another. Headquartered in Silicon Valley DrChrono, with iPad platform provides electronic medical services, free version of the application can achieve a variety of functions: allows users to enter electronic medical records, arranging patient appointments, oral disease converted to text notes and photographs and video, writing and sent to the diagnosis pharmacies, etc., in order to reduce the workload of doctors; and value-added version of the charges which, for the hospital to provide greater storage capacity and medical billing and other functions.
DrChrono founded in February 2011 when the receive $ 675,000 in seed money, and later received the well-known incubator Y Combinator funding agencies. Founded in 2007, another of Practice Fusion, business is also a cloud to doctors electronic medical records, including records visits information, see the medical records, appointment registration, electronic prescriptions, laboratory orders and collect open test results, see the online health patients information. The early days of the Practice Fusion was primarily in charge mode, the brink of collapse because of profit difficulties. But the Obama administration bill requires the introduction of electronic health care system to achieve transformation, the implementation of electronic medical records and medical subsidies, the company came to life, and to establish free strategy to expand the size of the user, and thus attract investors, its current user more than 100,000 more medical records database as much as ten million copies and has been successful in several rounds of a total of up to $ 36 million financing.
Government assistance comprehensive medical information service platform
Although China has yet to have similar specific electronic medical record providers appear, but with the advantage of quick and easy, the application of information technology in China has been the growing popularity of the top three hospitals. From the People\\ s Liberation Army 309 Hospital of a case shows that when the patient\\ s condition suddenly turns dangerous, you can not back to the doctor the first time in the mobile medical workstation login through the iPad, access to workstations in the radiology records of patients, ultrasound, pathology and other imaging, ECG, monitoring, anesthesia, chemotherapy, radiotherapy, clinical diagnosis and treatment of electronic medical records and other information, real-time basis to understand the patient\\ s condition and the latest test results, issued instructions on the breathing machine, 30 seconds after the nurse had to push the ventilator to the bedside. A related statistics show that 926 hospitals surveyed, 70% have established a nurses station and other information systems in the laboratory, radiology, EKG and other key sections of the information system construction, and has been prepared to establish the proportion of respectively 66%, 60%, 48% (table).
The application of intelligent systems to simplify the work condition information transmission, integration and other aspects, the faster the patients get good relief Needless to say, but also enhance the efficiency of medical diagnosis and hospital management, granularity, and thus further enhance the hospital\\ s profitability. This is reflected in the chain of clinics on the more obvious, in view of information systems and operational ease of a high degree of replication, making the chain mode, the ability of scale and cost savings multiplied.
Generally speaking, conventional support each doctor clinic support staff of about 4-5, and by means of electronic medical records and other information, the United States One Medical Group\\ s clinics only 1.5 or less. Management to reduce operating costs while the clinic, doctors have more time to answer patient\\ s questions, the experience of both doctors and patients have been enhanced. In the profit model, One Medical support of the U.S. most insurance programs, but will charge an annual fee of $ 149-199. The company currently operates in San Francisco and New York, nine clinics, after five totaling $ 46.5 million financing, will be extended to 2011 years of its Silicon Valley and Washington, DC, opened five new clinics.
In China, most of the public hospital system is subject to the plight of the more difficult chain of copy medical information on the profitability of significant improvement is not obvious, and integrated medical information system with the ability of all levels of government, as the establishment of standards important promoter. Some of the first local government has begun to establish regional information service platform, to explore a sustainable mode of information, such as the Zhongshan municipal government on the design and planning of the trilogy, pay by the Government for the construction of regional health information service platform, and through secondary data development to attract pharmaceutical companies, health management companies; also the terminal based on personal family business, the establishment of dynamic information health records, practice management fees. It is said that this program has attracted both Huawei and other UF class enterprise software and also provoke the Legend of the Star, Oak Delin, Kun Jiuding, Xun Xiang investment venture bodies.
Although planning is still in the exploratory stage, the link is clear from the design to the actual implementation is still lagging behind, but the hospital beyond the single, integrated community-based management model may be a future trend. The next long period of time, local governments have put up the Ministry of Health is to promote health information technology will be the main force. The inter-regional cooperation to share medical information for health care resource constraints and uneven regional development in China, more efficient means to save medical resources, medical information management vision for the fine may eventually become a reality.
Rapid growth of software service providers will be
Government boost, hospitals enthusiastic early adopters, a huge growth potential has also been given information service is worth looking forward to the new space, according to IDC, by 2010, China\\ s investment in health care IT market reached 120 billion. The next five years, China\\ s health information services market will be an annual growth rate of 15-30%. CCW Research predicts that in 2011 China put into health care information technology industry, the relative total growth of 25.5% in 2010. The software services faster than hardware development, according to the GMP consulting research, the investment structure, future medical information market will further decline in the proportion of investment in hardware, software and services, while the proportion of investment will be increased year by year.
High growth is expected to attract massive capital into the industry, international companies, Intel is the number of separate parallel digital medical enterprise, mobile marketing industry, others such as IBM, Oracle (Oracle), Cisco (Cisco), are also set up a professional the medical industry sectors. Domestic manufacturers, the focus on health information technology companies listed on GEM, such as Wei-ning Software (300 253), Silver River shares (300,020), etc., have been confirmed with high growth performance of the importance of this market and prospects. Main business covers the intelligent transportation, and medical wisdom of the Silver River shares, substantial growth performance during the first half of 2011, which the wisdom of medical service revenue 72,362,900 yuan, an increase of 208.47%.
Recently, from the whole health care system integration provider cloud, down to the sub-sub-industry software provider, a new round of merger integration is surging.

China s exports to Russia in 2010 Medical Device reproduction highlights
2010 reproduction of the new highlights of Pharmaceutical Trade Russia: total $ 675 million annual imports and exports, an increase of 32 percent, with exports to new highs, reaching $ 630 million, an increase of 39%.
Western products exports was significantly
2010 China Western products exported to Russia $ 384 million, an increase of 33%. Among them, the medicine raw material exports to Russia are still the main species, the proportion of 50%, and exports amounted to $ 331,000,000, an increase of 29%. Export varieties mainly amino acids, antibiotics and anti-infective class-based. It is worth mentioning that Western medicine with exports amounting to $ 20,430,000, an increase of 65%, the first time Russia has become China\\ s main exports to one of Western medicine. With the variety of China\\ s more preparation by the Russian drug registration and price advantage, 2011, the export of Western medicine is expected to reach $ 30 million.
The export of Chinese products is still stable
Chinese products exported to Russia $ 7,110,000, an increase of 50% though, but the medicine has been the export of pharmaceutical products in Russia, the proportion of the smallest, only about 1%, and the export situation is not stable enough, or often a trade surge dropped phenomenon. For example, last year, Chinese medicine, Chinese herbal medicines and Pieces on the export of Chinese herbal medicines for domestic prices rose a larger reduction in varying degrees, while the ranks of instability is the importer a factor affecting exports.
2010, a large increase in exports of plant extracts, the export value of $ 3,394,500, an increase of 284.64%, as exports of Chinese products in recent years, a new bright spot. It is understood that, because some plant extracts export fails encoding declaration, so the plant extracts in China\\ s exports to Russia much more than the actual amount.
Prospects for exports of medical equipment
Russia is China\\ s leading exporters of medical equipment in recent years, Russia\\ s export growth accelerated. Exports $ 238 million in 2010, an increase of 48%.

Benefiting the first half of our Medicaid spending 5.07 billion
Medical assistance to ease the public health burden of living, the government of the people is reflected in the care of people s livelihood. I believe that the cause of the medical assistance of how, in large part to reflect a country s level of development, or is their position in this country where placed. This paper briefly describes the recent days of China s medical assistance in the relevant circumstances.
Ill medical assistance is relying on urban residents (workers) of the basic medical insurance and new rural cooperative medical billing platform, capital investment, the service platform sharing, information sharing, synchronous settlement payment, management and operation specifications, rescue effect is obvious, that the poor people to provide fast service, covering urban and rural areas, a new scientific and standardized system of medical assistance. Including rural five of its aid target object, towns are unable to work, no income, no statutory dependents age support staff, Ministry of Civil Affairs on a regular basis to enjoy the benefits of quantitative living retired workers, etc. to streamline the 1960s.
Standards of urban and rural medical assistance is aid by the county to develop according to their economic situation, which will inevitably be different standards of relief. Implementation of local management of urban and rural medical assistance, including urban and rural low relief objects objects, rural five-guarantee objects, urban and rural people with severe disabilities, urban low-income seniors and so on.
So let s look at what the medical aid around the how.
First, Yichang: the proportion of poor people on Medicaid to 50%
August 8, Yichang Municipal Finance Bureau jointly with the Ministry of Civil Affairs issued a "city on the appropriate adjustments to the relevant social assistance policy," which will Yichang city medical assistance percentage of urban and rural poor people to 50%, and provides for urban and rural low Yichang City objects, rural five-guarantee objects, poor special assistance, the difficulties low-income urban families and other objects by the City District Government to grant aid of objects, increase the proportion of hospital pays the cost relief to 50%, capping line 6000 yuan; special needy people a relief can enjoy two years, the maximum amount of aid to 1.2 million.
In addition, the notice also implemented a classification of urban residents relief, where the object is to protect the town of "three no" object, in full security implemented on the basis of guaranteeing payment of additional per person per month 200; of serious illness, severe handicapped persons, or their children are receiving compulsory education and the affordability of tuition significantly more than the family, as well as husband and wife to support dual-old laid-off and independent non-income elderly household objects and other special problems of its own fixed additional temporary grants.
Second, given the West: "five in one" medical assistance mode PWM
This year, Dingxi city to seriously implement the urban and rural medical assistance and temporary assistance policies, and actively explore the "Participating insured, hospital assistance, illness relief, aid and charity aid clinic" medical assistance mode, standard rescue procedures and increasing the relief efforts to enhance aid the effect. In the first half, a total of 3.43 million yuan of funds urban and rural temporary relief, aid rural poor people 7147 (times); distribution of urban and rural medical assistance funds allocated 41.09 million yuan, helping urban and rural poor people 35 454 persons (times). At the same time, launched the "poor families with congenital heart disease medical assistance activities", Paimo reported the first 205 heart patients, surgery 63 eligible, 52 have completed surgery; present, the "women s health care aid poor families two cancer affected women activities are also being orderly manner.
Third, Qiqihar: 31 million poor medical aid group "zero time"
Qiqihar City, past medical assistance, not only by disease restrictions by major diseases, and hospital medical expenses incurred after the urban residents by the new rural cooperative medical insurance or the cost of medical claims must start with individuals after the advance, after discharge, with relevant documents and materials to the residence area of ??the community (village) for medical assistance, the district offices (township people s government) and the regional civil affairs department and approval, to be able to meet aid conditions, access to medical aid.
In accordance with past procedure, applications for medical aid relief objects in the entire process takes about three months, to rescue the object a lot of inconvenience.
July 31, Qiqihar City, urban and rural medical assistance "one stop" real-time settlement patterns within the city limits was the first test run. Implementation of urban and rural medical assistance stop real-time settlement, the abolition of restrictions disease hospitalization assistance, changing layers with documents submitted, the approval of the centralized approach, which greatly simplifies the application approval process aid for rescue object to provide a more convenient and efficient medical assistance services.
Other regions, Hubei, Fukang, Chengdu, Anhui, are also frequently came Herald, for everywhere the masses in a positive medical life and work.
In view of the cause of medical care around the country to be so in full swing, our first half of the country s medical care situation is bound to be some good scenes. Recently, the Ministry of Civil Affairs issued "Civil Affairs Statistics Quarterly (2011 Q2)." "Quarterly Report" shows that the first half of this year, China s urban medical assistance expenditures of 15.8 billion yuan, rural medical aid expenses 34.9 billion, total expenditure of urban and rural medical assistance 50.7 billion. "Quarterly Bulletin", this year s January to June, China s urban medical assistance 2.144 million people, the civil affairs departments to participate in Medicare funding are 7.687 million people; 4.739 million people in rural medical assistance, civil affairs departments to participate in funding cooperative medical 25,870,000 passengers. In the first half, China s actual expenditures for the District operating expenses 106.9 billion yuan.

Application of medical sensors, design challenges and trends
Wireless sensor networks (Wireless Sensor Network) is a combination of sensor technology, embedded computing technology, modern networking and wireless communications technology, distributed information processing technology and other areas of technology, emerging technologies, the technology has a wide range of scenarios.
As technology advances, WSN (Wireless Sensor Network) will be in many aspects of medical practice have a profound impact. This article discusses the health care system, wireless sensor network architecture and design of the general principles of monitoring nodes.
Wireless sensor network architecture
Layout of the region in monitoring a large number of sensor nodes, nodes using self-organization for networking and the use of wireless communications technology for data forwarding, each node has to forward data acquisition and data fusion of the dual function. Node itself, the information collected to other nodes and forwards the information to its preliminary data processing and information fusion to adjacent nodes in relay after the transmission to the base station, then through the base station to the Internet, and satellite transmission to the end user.
Wireless sensor network node is the basic functional unit, the specific application of different design are not the same node. The basic building blocks of the sensor nodes are: sensing unit, processing unit, communication unit and power supply. In addition, according to the specific application requirements can add functional unit, such as: positioning systems, mobile systems, and power supply system and so on.
Wireless sensor networks in health care in the application
Wireless sensor network using its own advantages (such as low cost, simple, rapid, non-invasive real-time collection of patient\\ s physiological parameters, etc.), so that in medical research, general hospital / ICU ward or family day care and other areas in great potential, is a hot area of ??research.
Placed in the patient body parameters for the detection of micro sensor nodes, the patient\\ s heart rate, blood pressure, ECG, heart sounds and other real-time remote monitoring of physiological parameters, and the information is transmitted to the monitoring center summary, the timely processing and feedback; use WSN is to collect long-term observer of human physiological data, the understanding of human health and the study of human disease are very helpful. In addition, drug management and development of new medicines, blood management and other aspects, also has its own unique application. In short, the wireless sensor network for the future of remote medical monitoring system provides a more convenient, low-cost means of achieving.
Wireless sensor networks based on the structure of the health care system
Wireless sensor networks based on the medical care system mainly consists of medical sensor nodes, base stations, medical care (medical SINK node) and community / hospital care centers these parts.
Medical sensor nodes and base composition of personal care / family or ward wireless sensor networks, such networks can be composed of multiple community or hospital care throughout the network, or even a wider range of remote medical care system. First, medical sensor nodes collect physiological parameters, and simple processing parameters collected by the wireless communication directly or indirectly-by-hop way to transfer data to the base station. Monitoring station for further processing of the data transmitted to the monitoring center, monitoring center for analysis and processing, and timely information on patient feedback. Care centers can also use a variety of ways (Internet, mobile communication network, etc.) for remote data transmission, sharing information with other care centers.
Medical sensor node design
The basic structure of medical sensor node includes processing module, sensor module and wireless transceiver module and power supply modules.
Sensor module is used for external sensor signal perception, acquisition, conversion. Is the node real contact with the external semaphore module. However, medical sensor is a living body is measured. In particular, the body can be said that the world\\ s most complex systems, there are various physiological variables highly correlated and difficult to close. Therefore, the phenomenon of medical sensors removed from the prediction of many physical volume, to obtain reliable and meaningful measurements, while also ensuring the safety of the measured object.
Most of the human body is weak because the signal parameters, generally only a few mV level, or even lower, and there is a variety of noise (measurement noise, equipment noise and friction with the body itself, the instrument noise, etc.), frequency interference (there are around 50Hz by the measurement environment The electromagnetic fields) and a variety of noise and other negative factors. Therefore, the specific medical sensor node design, add analog processing module, which generally includes the following sections: amplifier circuit, filter circuit, notch circuit and modulus (A / D) conversion circuit. Amplifier circuit in the node design commonly used in multi-level amplification (three or four), the last stage amplifier circuit in addition to the general also has a zoom function to enhance the functional level; filter circuit: the circuit should be simple to meet, a reasonable cut-off frequency, flexible easily adjust the low pass cutoff frequency, etc., a reasonable filter out high frequency and low frequency signal interference; notch circuit: the widely used symmetric double T notch filter, active RC or switched capacitor integrated and non-symmetrical parts RC notch network, etc.. In short, the analog circuit processing module mainly collected signal amplification, filtering, notch, treatment, removal of signal noise, interference, and to extract useful signal.
Processor module is the core of the sensor nodes, the nodes responsible for device control, task allocation and scheduling, data integration and transmission. Currently the processor module is used frequently in Atmel\\ s AVR series of microcontrollers, TI\\ s MSP430 ultra low power processors, Motorola Inc. and Renesas\\ s 32-bit embedded processor as well as the ARM processor chip. In the node design, the processor module must be programmed to achieve acquisition and control of the sensing module, A / D conversion and control the implementation of wireless communication transceiver module.
Transceiver module for wireless data communication between nodes. More applications in the wireless area wireless transceiver module Chipcon\\ s CCl000, CC2420, CC2430. Commonly used in wireless communication technology: IEEE802.1lb, IEEE802.15.4 (ZigBee), Bluetooth, UWB, RFID, IrDA (infrared), etc. Monitoring system they use IEEE802.15.4 (ZigBee), Bluetooth nodes and nodes to achieve the data communication between the base station.
Power supply module provides power for the node, is the basis for the entire wireless sensor node module. However, limited by the size of the node, the sensor node\\ s energy is very limited. Thus, in the node design, low power, high accuracy as the main requirement, adopted a series of effective measures to save energy. In addition, medical sensor nodes can not be frequent replacement of batteries, affect people\\ s normal life. Therefore, the design of medical node should have a longer life cycle.
Health monitoring system for wireless sensor networks present challenges
Although wireless sensor networks in organizing medical care system has its unique advantages, but also applied to the actual existence of the following health challenges:
Dynamic network of nodes with large-scale network mobility management: When the monitoring system to a community, city or even country, their network is huge, and the monitoring node and the base station has a certain degree of mobility. Therefore, we must design an appropriate management structure of the network topology and node mobility management.
Data integrity and data compression: the node can take up to 24 hours of monitoring body parameters, the node to the quantity of data collected, and the node\\ s storage capacity is small, often using compression algorithm to reduce data storage and transmission capacity.
However, traditional data compression algorithm is not too much overhead for sensor nodes. In addition, the compression algorithm can not damage the original data, otherwise it will cause errors in the diagnosis of the patient.
Data security: wireless sensor network node using a self-organized network, vulnerable to attack, in addition, patient information be kept confidential. However, very limited computing power sensor nodes, traditional security and encryption technologies are not applicable. Therefore, we must design a sensor node for encryption and decryption algorithms.
Summary and Outlook
As technology advances, wireless medical sensor nodes gradually to multi-parameter, intelligent, miniaturized, low power consumption direction, wireless sensor networks will gradually be actually used in the medical field. Development and the formation of a ward and intelligent community health care system is the development trend of domestic and foreign.
