In history, the development of science and technology has brought changes and progress to various industries. The medical field has made a great leap forward in modern times, and has stimulated the development of a series of industries related to it. Medical devices occupy an important position in the medical related industries. In recent years, the upgrading and development of medical devices by scientific research institutions outside China are obvious to all, and gradually improve the treatment experience of patients in clinical aspects.

At the same time, the higher medical level has also put forward more stringent requirements for the production of medical devices. In the aging trend of the population accelerated, the pursuit of painless treatment of the present, while affected by external policies and other factors, the research and development of medical devices is facing new challenges. With the expansion of the global consumer market for medical consumables, plastics are more and more widely used in the medical field, and plastic devices have gradually replaced some traditional medical devices.

From the material point of view, compared with the metal or glass material used in traditional medical devices, plastic has good chemical inertness and biosafety, and is cheap, easy to form, relatively tough, suitable for one-time use, health and safety. At present, the concept of environmental protection has been deep in all walks of life, the research and production of medical materials is no exception, biocompatible degradable materials are becoming a new industry hot spot.

For example, high-performance special engineering plastic PEEK(polyether ether ketone) has good biocompatibility, biostability and X-ray transparency, but also has excellent mechanical, physical, chemical, electrical, thermal and other properties, can be used for the additive manufacturing of three-dimensional plastic parts of human medical implants. There have been cases in artificial spine, orthopedic surgery, sports medicine, cardiovascular and other aspects. When it comes to degradable medical equipment, cardiovascular stent has a place, compared with traditional stent, degradable stent in the human body after a period of use to decompose into harmless things, reduce follow-up medical problems, to improve the quality of life of heart patients is of great help, the current advanced degradable plastic stent has been approved by the United States FDA review.

According to the forecast of China Pharmaceutical Industry Information Center, China's medical device market will exceed 600 billion yuan in 2019, and the compound annual growth rate will reach 16.8%. At the beginning of this year, Baidu, Tencent and Huawei have entered the medical device market, which is expected to further promote the development of the industry. At the 2019 International Rubber and Plastics Exhibition held in May this year, many exhibitors also brought new achievements in the field of medical plastics, the research and development of new materials, to the injection molding and extrusion molding of precision instruments, the development of medical plastics has shown a thriving trend. From this, we can see that plastics do have great potential in the medical field.

Medical equipment is a capital-technology dual-intensive industry, for a long time in the situation of monopoly by developed countries such as Europe and the United States, China started late in this respect, after years of development, gradually showed a tendency to catch up. Especially in recent years, the implementation of major medical measures such as rural medical reform, grassroots hospital construction and community health service center reflects the Chinese government's emphasis on medical health, and the technical innovation support for the medical device industry is also gradually increasing, which provides a good growth environment for the development of China's medical related fields.

Medical plastics are an important part of medical polymer materials, and China has more room for development, especially in the field of disposable polymer medical devices. At present, there are still not many enterprises with strong strength in the production of medical plastics in China, although PVC and PP are basically made in China, but PE, PC, ABS and other medical plastics are still dependent on imports, and the innovation shortboard will still be a factor restricting the development of China's medical plastics industry for a period of time in the future.

Conclusion: According to the latest report released by the US market Research company Grand View Research, it is expected that by 2025, the global medical plastics market revenue is expected to reach 336 billion US dollars. The medical field has developed rapidly in recent years, and plastics have played an indispensable role in the manufacturing of medical devices and the innovation of medical materials. At present, China's biomedical materials are mainly used as medical devices in clinical applications, and have become an important basis for the entire medical device industry. At present, compared with foreign enterprises, China is still relatively weak in the regulation, research and development, production and other aspects of medical plastics, but depends on the national encouragement policy and the influence of good industry development trend, in the near future, China's medical plastics industry is expected to usher in the golden period of development.
