Xiao Bian recently has been plagued with a problem. What are the mysterious places in medical textiles? What is medical textiles? Does it have more requirements for its production? Let's take a look at medical textiles together with Xiao Bian today.
In fact, medical textiles are not as imaginary as it is mysterious. It refers to a generic category of textile materials featuring medical applications, including general hospital supplies, medical supplies for external use, medical protective supplies, medical functional supplies, and hygienic products. Health products, textiles for medical devices and instruments.
The use of textile materials in medicine in China dates back 4,000 years ago. At that time, our ancestors began to use sutures, linens, and hair to sew up wounds known in life. With the development of the times, the development of science and technology, textile materials The medical application has penetrated into various fields of disease diagnosis and treatment. Up to now, textile materials have been widely used in surgical dressings, artificial organs, replacement devices, prosthetic materials, medicines, health care, plastic surgery, and diagnostic and therapeutic instruments, which means that they have made progress in medicine. Irreplaceable promotion and promotion.
In fact, when it comes to the broad market for the development of the medical textile love market, it must have many advantages. What are the advantages of medical textiles?
1. The permeation absorption function of large surface area per unit volume can be fully exerted.
2. Lighter weight, better mechanical and physical properties.
3. It can be knitted arbitrarily to make it have subtle movement adaptability in mechanics.
Textile materials have very practical value in medicine. The earliest use of medical textile materials: cotton, wool, silk, hemp and other natural fibers. With the continuous development of science and technology, medical textiles have opened up new raw material markets such as cotton, polyester, acrylic, viscose, and many other chemical fibers. At the same time, the promotion of medical non-woven fabrics is the further expansion of chemical fiber applications, so the development of medical textile materials is showing greater vitality.
Xiao Bian think that since it is a medical textile that must have special requirements, what special requirements are there?
1. We must meet the requirements of disinfection resistance. In fact, we all know that medical supplies need to be disinfected, not just medical devices. Actually, regardless of whether medical textiles are used as medical supplies or nursing care supplies, various special medical textiles need to be used. Disinfection and sterilization are carried out to eliminate infection, so it is required that no change in physical and mechanical properties occurs during the entire disinfection process.
2 must meet the requirements of biosafety, the selected medical fiber materials should have specific chemical properties and biological properties, chemical properties, including water absorption, dissolution, adsorption, sustained release, biodegradability, drug resistance , oxidation resistance, etc., then the biological properties include, toxicity, inflammatory, coagulation, antigenicity, allergic, hemolytic, carcinogenic, etc., used in medical textile materials, skin contact and blood contact type or human body Implantable types all involve biosafety issues. If these materials are not properly selected, they may be caused or caused by inappropriate selection of properties such as: infection, necrosis, chronic inflammation, thrombosis, sustained release toxicity, cancer induction, skin irritation, circulation Barriers, nerve numbness and a series of local discomforts. Life safety is no small matter, so these choices are particularly important and must be carefully considered.
3. Biocompatibility is also very necessary. Medical textiles are in direct contact with living tissue and blood during use. Therefore, they must have good biocompatibility, including blood compatibility and tissue compatibility, such as polyurethane. Polyurea and polyurethane urea are commonly used in aortic structures because of their good blood compatibility and mechanical properties. Carbon fiber also has a good blood compatibility for a solid structure.
4. Medical functionality, which is the most important function of medical textiles, depending on the application of the three main aspects of effectiveness, convenience and comfort. Effectiveness refers to the effectiveness of medical textiles in their application, such as the ability to absorb liquids (absorbing, sucking blood, inhaling, and inhaling) medication functions (hemostasis, pain relief, infection prevention, etc.) Mechanical functions (stitching) , Cladding, Support, Isolation, Fixation) Selection of functions (permeation, separation, adsorption, transport). Convenience refers to the reduction of suffering and inconvenience of the patient through the use of medical textiles, providing convenient conditions of use such as waterproofness, slip resistance, self-adhesion, elasticity, and curability of the bandage. Comfort is to further improve the performance of medical textiles to make patients feel comfortable, such as fluffy, delicate touch, breathable and breathable, etc.
5. The aging resistance is also very important. The aging resistance of fiber materials is the response of organisms to materials, including physical and chemical properties. Usually we should stop this change from happening. Therefore, medical textiles have very high requirements for resistance to biological aging.
Said so many Xiao Bian is to tell everyone that the medical textile market has great potential, but in the production and management process must be strictly regulated by the Pharmacopoeia, carry out strict quarantine inspections, including a variety of animal experiments and human trials, or that sentence life security is no small matter, when we are sick hospitalized when we everyone wants to use their own medical textiles can secure qualification, let your body recover quickly and regain health, we all understand these requirements yet small series after ~ You will also be introduced to a lot of special textiles, more fresh information, please feel free to pay attention to China's fabric network oh ~ ~
