As a very important material, plastic has been widely used in the medical field. From pharmaceuticals, pharmaceutical packaging, to disposable medical devices (such as drip bottles, syringes, etc.), non-disposable medical devices (such as measuring instruments, surgery) Instruments, etc.) have plastic traces.
In 2011, the size of the global medical device market exceeded US$310 billion, and China’s demand for medical plastics has also increased at an annual rate of 15% to 18% over the past 15 years. As the population ages, the environment deteriorates and people’s expectations for improving health care are met. The continuous increase will promote the continuous growth of the domestic disposable medical device market.
The application of plastics in the production of medical devices will promote the use of plastics. It has advantages in improving product performance, trial-producing new products, saving non-ferrous metals, simplifying processing techniques, increasing labor productivity, and reducing costs. Plastic medical devices have many advantages in the future medical field. In addition, its market influence will increase. Medical device designers are expanding their understanding of new thermoplastic materials and are continuously developing them for use in medical products.
Plastics have several advantages in the medical field:
1, light weight, use of labor-saving, help to reduce the fatigue caused by long-term surgery doctors. More suitable for human blood and muscle tissue, so more effective.
2, strong toughness, strong anti-permeability, durable, some plastic can also be used normally at high temperatures.
3, with transparency, can be better observed in the medical process, especially in the surgical process.
4, easy to form, suitable for the production of a variety of modeling, complex structure of medical equipment and supplies, and the use of low-cost production process. The use of disinfectant or high-temperature sterilization does not occur corrosion or color change phenomenon.
5, compared with other raw materials such as metal, the cost is low, more suitable for the production of disposable loss products, used as a packaging material after sterilization will help reduce the risk of infection.
6, Compared with fragile materials such as ceramics or glass, the use of plastics is safer, especially for packaging materials.
In addition to traditional medical plastics, such as PP, PVC, PE, and silicone rubber, which are commonly used in the medical device industry, some high-performance materials such as polyetheretherketone (PEEK), biocompatible polycarbonate (PC), thermoplastic elastomers ( TPE) etc. are all important materials to promote the development of the medical device industry.
Among them, PEEK has strong corrosion resistance, hydrolysis resistance, chemical resistance, and in particular inertness to body fluids. It can be used in implantable medical devices that reduce patient suffering, such as gastrointestinal stents and implantable body fluid pumps. The pain caused by traditional puncture surgery to patients; and medical-grade polycarbonate to meet the biocompatibility, strong corrosion resistance and the advantages of not easily broken, is the preferred capsule endoscopic shell material.
Poly Dragon medical grade material is non-filled PP material PPH02.
