What are the medical supplies?
Legal subjectivity:

What aspects of medical product information are closely related to our daily work or life? So, you can't just hear about it, but you don't know how. The following small series has compiled some related contents to share with you. Welcome to read, I hope it will help you. 1. Medical product requirements 1. Some mechanical properties. 2. Excellent chemical stability. 3. Excellent physiological compatibility. 4. Excellent antithrombotic performance. 5. Excellent sanitary performance. 6. Various disinfection treatments can be carried out. 2. There are many kinds of commonly used medical plastic products, which can be divided into three types according to the contact relationship with human body: implantable, long-term contact with human body and short-term contact with human body. 1 Implanted in human body, 2 in long-term contact with human body, 3 in short-term contact with human body, and 3 in common use for medical products. Polyurethane is called polyurethane, which is the general name of macromolecular compounds with repeated carbamate groups (NHCOO) in the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate with dihydroxy or polyhydroxy compounds. In addition to carbamate, polyurethane macromolecules can also contain ether, ester, urea, biuret, allophanate and other groups. Polyether urethane can be used to make artificial pacemakers, artificial blood vessels, artificial bones, artificial esophagus, artificial kidneys and artificial dialysis membranes. 2. Silicone rubber is one of the most commonly used raw materials for medical plastics, which has excellent aging resistance and antithrombotic performance, but its bending resistance is average. Silicone rubber is mainly used for artificial trachea, artificial lung, artificial bone, silicone rubber duodenum tube, silicone rubber artificial blood vessel and silicone rubber tympanic membrane patch. 3. Fluoroplastics have excellent corrosion resistance and biological aging resistance, and have good physiological compatibility with human body. Commonly used in artificial blood vessels, artificial hearts, artificial heart valves, artificial esophagus and so on. 4. Polymethyl methacrylate is the earliest plastic used for artificial skull. At present, it is mainly used for artificial heart, artificial heart valve, artificial bone, artificial tooth, contact lens and artificial cornea. 5. Polyamide is mainly used for artificial blood vessels, artificial dura mater, artificial bones, artificial teeth, artificial tendons, joints and intrauterine devices. 6.UHMWPE has good physiological compatibility and physiological inertia, and is a newly developed medical polymer material. Mainly used in heart valves, artificial joints and birth control products. Four. Plastic medical containers for medical containers mainly include infusion bottles, infusion bags, peritoneal dialysis night bags, blood transfusion bags, plasma bags, and concentrated platelet preservation bags. Medical container materials mainly include polypropylene, high density polyethylene, low density polyethylene, polyvinyl chloride, ethylene-vinyl acetate polymer, polyester and so on. 5. Plastic materials for disposable medical supplies and appliances: syringes, polyethylene, polypropylene, polystyrene, polycarbonate blood transfusion devices, thoracic and abdominal cavity drainage devices, PVC blood circuits and connecting tubes, polycarbonate tubes, PVC, polypropylene, PVC, various night tubes, polyethylene, polypropylene, PVC, oxygenator and accessories, polyethylene examination appliances, polyethylene, polypropylene, polystyrene and ABS patient equipment. Polypropylene operating room equipment polyethylene, PVC treatment equipment PVC, EVA anesthesia equipment PVC, EVA bandage polyurethane foam, PVC, room temperature vulcanized silicone rubber are all related knowledge compiled by Bian Xiao. I believe everyone should know something about it. If you still don't understand what is used in medical product information, you can read other articles about life cats, hoping to bring you help.
