Currently, the trend of aging and affluence of the world's population provides the possibility of growth in healthcare consumer spending, and at the same time lays the foundation for the development of the medical device industry. Despite the global economic recession, the medical device industry still maintains a good momentum of development. According to a U.S. survey, the U.S. market for medical automation technology was $12 billion in 2008. The market is expected to grow to $13.1 billion in 2009 and reach $23.2 billion in 2014.
iSuppli notes that medical electronics sales in China will grow 18.2% in 2009, from $3.3 billion in 2008 to $3.9 billion. This strong momentum will continue over the next few years, with a compound annual growth rate of 21 percent, rising to $8.6 billion by 2013. Experts predict that the medical device industry by 2010, China's medical device market capacity will reach 120 billion yuan, but the current domestic production of medical devices more than 90% of the low and medium-grade conventional products, to speed up the development of the medical device industry has become China's economic development of an important strategic deployment. Medical digitalization and informatization is the main direction of global medical device technology development, and it is the most important technical guarantee to realize medical "non-destructive" and "precision". Digital medical equipment is the foundation of medical informatization, digital medical technology is the core technology of modern medical equipment, digital medical equipment and instruments are typical numerical control automation system. Digital and information-based medical products formed by the industry is a highly concentrated knowledge-intensive industry of new technologies, but also the medical device industry in the highest value-added (an average of more than 40-50%), the international and domestic markets in the field of the most intense competition. The realization technology of medical automation 1.Embedded technology The application of a large number of medical instruments in the field of medical instrumentation, such as cardiac pacemakers, radiological equipment and analytical monitoring equipment, all require the support of embedded systems. A variety of laboratory equipment, such as muscle current tracer, discrete photometric chemical analysis, spectrophotometer, etc., need to use high-performance, specialized DSP system to improve its accuracy and speed. After the introduction of embedded systems, the functions and performance of various existing monitors will be substantially improved. With the development of information technology, digital products unprecedented prosperity. Embedded software has become a key factor in digital product design innovation and software value-added, and is an important reflection of future market competitiveness. From the field of medical instruments, in addition to new sensing and detection technologies are constantly used to promote, the analysis, storage and display of the collected information also put forward a higher goal. This requires modern medical instruments to have more powerful computing and storage capabilities as well as more stable and reliable performance. In addition, medical instruments as a special industry, but also requires equipment to achieve a higher level of environmental protection requirements. How to further intellectualization, specialization, miniaturization, and at the same time to achieve low power consumption, zero pollution, will be an endless pursuit of the process, which provides a broader world for the application of embedded systems in medical instruments and higher requirements. According to the "Eleventh Five-Year Plan", the pilot coverage of the "New Rural Cooperative Medical Care" will be gradually expanded in 2007, and basically implemented in the whole country in 2008 to realize the basic coverage of rural residents in 2010, which will be a major benefit for China's medical instruments. At the same time, the product structure of China's medical instruments has become more and more complicated. At the same time, China's medical instrumentation product structure adjustment, the application of embedded systems in medical instrumentation also provides a good opportunity for development, but also to the embedded system developers put forward new challenges 2. Wireless technology In recent years, wireless communication technology at home and abroad in the medical market has been widely used, the rapid growth of wireless medical equipment applications. The U.S. medical Wi-Fi market reached $495 million in 2003, which includes Wi-Fi devices, Wi-Fi networks, system integration, medical monitoring, control and optimization. By 2010, the U.S. Wi-Fi market will be as high as $2 billion, while revenues from wireless network operations and related services will increase to $7 billion. Market participants estimate that this fast-growing market will give a strong impetus to the development of Wi-Fi medical devices, and it is expected that a number of Wi-Fi medical products will be introduced to the market. 3. Sensors In the modern and future information society, the information processing system to respond to the various changes in nature and society, first of all, the need for sensors will be a variety of information from the outside world next and converted into information processing unit in the information system (i.e., computers) to be able to receive and process the signal. At present, biosensors are used more in the field of medical, pharmaceutical, bioengineering, environmental protection, food, agriculture, animal husbandry and other life sciences are closely related to some areas. With the further informatization of society, biosensors are bound to gain more and more extensive applications. It is understood that such as microfabrication and miniaturization and other rapid technological advances are making the biosensor began to penetrate the developing world, in the United States, Europe, China and India's steady growth will continue to help drive the overall global sales at a rate of 9.5% growth, and will be in 2009 exceeded 4 billion U.S. dollars. The direction of biosensor R&D has changed significantly in recent years in response to emerging biotechnology innovations in the areas of biocompensation chemistry, surface characterization, molecular labeling, and nanotechnology, and will drive the growth of applications in a variety of settings.
