With the rapid advancement of materials science and technology, new composite textile materials suitable for special medical applications have been developed. New medical textiles made from these materials are changing the existing clinical treatment model. Therefore, these new products will become a new hot product in the international medical device market. The following representative new types of new medical textile materials are introduced for reference in the industry.
Multi-Purpose Polyester-Wire Hollow Tubes A company in the United States has recently developed a new hollow tubular fabric material that is woven into a twisted shape using high-strength polyester (commonly used chemical fiber material) rayon and wire. It has a wide range of uses in clinical medicine, such as the repair of vascular rupture or the replacement of a damaged heart mitral valve as a "prosthetic" implant material.
According to reports, this newly-launched polyester-wire cross-linked braid not only has good rigidity, but also has excellent elasticity and good biocompatibility with the human body. It does not cause allergic reactions and can be processed into tubes. It can be processed into other shapes of medical materials, and is a new type of new composite medical fabric new material.
High-strength chemical fiber new materials that can replace metal materials So far, polyester and polypropylene chemical fiber raw materials occupy a considerable proportion in medical plastic products, because these two thermoplastic chemical fiber raw materials can be used to manufacture various commonly used medical fabrics. The product is low in price and the softness of the finished product after processing is good.
Recently, foreign manufacturers have developed a new type of polymer medical fabric new material for the manufacture of implantable device products. According to reports, the product is a new composite chemical fiber raw material product processed from two kinds of chemical fiber materials, aryl polyether ketone and high strength polyethylene. The high-strength chemical fiber composite material can be used for processing medical textile materials such as artificial blood vessels, which need certain strength and elasticity, and can also replace implantable prosthetic instruments made of metal materials such as stainless steel, titanium, platinum and nitinol alloy. product. What is more worthy of attention is that the new high-strength chemical fiber material is very similar to the characteristics of human tissue, and can completely replace the metal implantable device product, and its cost performance is high.
New medical fabric materials that can be absorbed by the human body Nowadays, the medical profession places high demands on the raw materials used in implantable devices, which must conform to the specifications and human adaptability of medical device products, and must be absorbed by the human body, so that the products can be It is automatically absorbed or decomposed within 1 to 2 years after implantation. With the rapid development of materials science and technology, foreign manufacturers have developed a variety of new materials that can be automatically absorbed by the human body. Among them, it has been approved for the production of implantable devices such as medical fabrics. The new raw materials are polylactic acid (PLA) and poly Ethylene glycol (PEG).
Polylactic acid is a new type of "bioplastic" which is made from corn starch and fermented into lactic acid and polymerized. It not only has certain rigidity and elasticity, but also can be automatically decomposed into lactic acid and finally excreted in the human body. . According to reports, the use of these two new materials can produce porous or compact new implantable materials, which have many new uses in clinical medicine. Such as: made "vascular patch", used to stop bleeding for severely damaged blood vessels, after the new blood vessels are long, the implanted polylactic acid blood vessel patch has been automatically decomposed, no need to remove surgery.

Oysters contain zinc, a trace element. As one of the essential trace elements in the human body, zinc plays a very important role in brain development and can increase synaptic transmission, that is, increase memory. (Supplement of vitamin a can prevent night blindness because vitamin a plays a regulating role in the development of the eyes.) Zinc can promote the absorption of vitamin a. Vitamin a is stored in the liver when it is not working, and zinc is needed when needed To mobilize.
