Summary

The biomedical materials sector is a cutting-edge field, and currently only two companies in the world, GE of the US and POLL, can independently complete the research and development and market operation of products. The remaining Japanese and American companies that produce related composite materials are using the base films of these two companies. Jia Membrane has already completed the research and development of the base film and composite products, and has reached the production standards of European and American companies in the industry. The company strives to complete domestic substitution within the next five years. In the medical protection field, Jia Membrane has reached the leading international level, and its products have been mass-produced. Currently, the company's protective product orders are sufficient. The PTFE medical protective materials developed and mass-produced by the company for medical protection are praised as "breathable protective clothing" due to their excellent protection, breathability, and aging resistance. They are medical protective products for the post-epidemic era.


Bio-medical filter membrane

Bacteria are typically larger than 1um in size, but the pore size of the PTFE membrane can be as small as 0.02um, allowing for ultra-clean filtration of gases and liquids. The self-cleaning function (coefficient of friction ≤ 0.04) of the membrane's surface can prevent bacteria from accumulating on the membrane. PTFE micro-porous membrane has good high-temperature resistance (260°C) and chemical resistance (strong acids and alkalis), it is hydrophobic (water absorption rate is about 0.001%-0.005%), non-aqueous solvent, and is an ideal choice for sterile exhaust of non-aqueous solvents, acids, and corrosive liquids. After being modified with hydrophilicity, it can also be used for bacterial filtration of aqueous solutions and the manufacture of various medical protective equipment.

New ePTFE Medical Protective Materials

The fabric is made of non-woven lining + PTFE film + non-woven lining composite. PTFE film is made of polytetrafluoroethylene as raw material, using special processes of calendering, extrusion, biaxial stretching, high-temperature setting, etc. to prepare, the surface of the film is covered with original fiber-like microholes, the porosity rate is above 90%, there are more than 90 billion microholes per square inch, PTFE film can block water droplets, particles, bacteria from passing through, but can allow water vapor to pass through, with excellent waterproof, breathable, moisture-permeable, bacteriostatic effects. The fabric has good color fastness to washing, can be washed ten times or less, prevent shrinkage, non-flammability, no toxicity and no irritation, no harm to the skin, wear resistance, etc. properties. Since the pore size of the PTFE micro-pore film can be controlled at around 0.2um, it is a new type of protective clothing fabric. After being composite with fabrics, it can be made into protective clothing to block viruses from passing through, and the material itself also has the function of waterproof and breathable, which brings better comfort to the user. The most important function of blocking bacteria and viruses is 100%, coupled with its high breathability, it allows the user's skin to breathe freely while wearing, so that the body can work in an oxygen-rich state. Humanized design, breathable, waterproof, bacteriostatic, flame-retardant, anti-static, anti-aging, anti-penetration, etc. functions, is the best equipment material for medical personnel.

Artificial organs

Artificial heart valves

A mechanical valve is an artificial heart valve made of man-made materials that can be implanted in the heart to replace a damaged natural heart valve, thus achieving unidirectional blood flow and possessing the function of a natural valve. The composition of a mechanical valve typically includes three parts: a rigid material used to make the support structure, a flexible material used to make the obstruction body, and a textile material used to make the valve ring. The support material is usually made of cobalt-chromium-nickel alloy, titanium, polyacetal resin, or polytetrafluoroethylene.

Preparation of artificial vessels

Artificial blood vessels are usually made of synthetic materials such as nylon, Dacron, ePTFE (expanded polytetrafluoroethylene), and the market share of ePTFE artificial blood vessels is relatively high. Artificial blood vessels are suitable for blood vessel bypass surgery in various parts of the body. The artificial blood vessels currently used in clinical practice include composite wall artificial blood vessels, autologous tissue sheet transplantation artificial blood vessels, Y-type artificial blood vessels, and conical artificial blood vessels.
