For medical product information what aspects are closely related to our daily work or life, has a close relationship, therefore, we can not only heard of, but do not know how it is specifically, the following Small editorial compiled some relevant content and share with you, welcome to your readings, and I hope to help you. First, medical products on the performance requirements of plastics 1. certain mechanical properties 2. excellent chemical stability 3. excellent physiological compatibility 4. excellent anti-thrombotic properties 5. excellent hygiene properties 6. can be sterilized in a variety of processing Second, commonly used medical plastic products There are many types of medical plastic products, according to the human body contact can be divided into implanted in the human body category, the long-term contact with the human body category and short-term contact with the human body three kinds. Contact class three. 1 implanted in the human body 2 long-term contact with the human body 3 short-term contact with the human body 3, the choice of commonly used medical products plastic 1. polyurethane one of the most commonly used medical plastic raw materials, with excellent physiological compatibility and anti-thrombotic properties. Polyurethane is known as polyurethane, is the main chain containing repeating urethane groups (NHCOO) of the macromolecular compounds collectively. It is formed by polymerizing organic diisocyanates or polyisocyanates with dihydroxy or polyhydroxy compounds. Polyurethane macromolecules, in addition to urethane, can also contain ether, ester, urea, urea, urea-based formate and other groups. Polyurethane urethane can be used in the manufacture of artificial pacemakers, artificial blood vessels, artificial bones, artificial esophagus, artificial kidney, artificial dialysis membranes and so on. 2. Silicone rubber, one of the most commonly used medical plastic raw materials, has excellent aging resistance and anti-thrombotic properties, but the resistance to winding performance in general. Silicone rubber is mainly used for artificial trachea, artificial lung, artificial bone, silicone rubber duodenal tube, silicone rubber artificial blood vessels, silicone rubber tympanic membrane patch. 3. Fluorine plastic has excellent corrosion resistance and biological aging resistance, and good compatibility with human physiology. Commonly used in artificial blood vessels, artificial heart, artificial heart valves, artificial esophagus. 4. Poly(methyl methacrylate) The first plastic used in artificial skulls. At present, it is mainly used for artificial heart, artificial heart valve, artificial bone, artificial teeth, contact lenses and artificial cornea. 5. Polyamides are mainly used for artificial blood vessels, artificial dura mater, artificial bone, artificial teeth, artificial tendons, joints and birth control. 6. Ultra-high molecular weight polyethylene With good physiological compatibility and physiological inertia, it is a newly developed medical polymer material. Mainly used for heart valves, artificial joints and birth control products. Fourth, the plastic selection of medical containers Plastic medical containers are mainly infusion bottles, infusion bags, peritoneal dialysis with night bags, blood bags, plasma bags and platelet concentrate preservation bags. Medical container materials are mainly polypropylene, high-density polyethylene, low-density polyethylene, polyvinyl chloride, ethylene - vinyl acetate **** polymer, polyester and so on. V. Disposable medical supplies plastic selection Products Material Syringes Polyethylene, polypropylene, polystyrene, polycarbonate blood transfusion device polyvinyl chloride Chest and abdominal drains polyvinyl chloride blood circuits and connecting tubes polyvinyl chloride, polycarbonate tubing polyvinyl chloride, polypropylene, polyvinyl chloride, various types of tubing polyethylene, polypropylene, polyvinyl chloride, various types of tubing polyvinyl chloride, polypropylene, polyvinyl chloride, oxygen concentrator and accessories polyethylene Inspection tools polyethylene, polypropylene, ABS Patient appliances Polyethylene, polystyrene, ABS Patient appliances Polystyrene, ABS Patient appliances Polyethylene, polypropylene Operating room appliances Polyethylene, polyvinyl chloride Therapeutic appliances Polyvinyl chloride, EVA Anesthesia supplies Polyvinyl chloride, EVA Bandages Polyurethane foam, polyvinyl chloride, room temperature vulcanization of silicone rubber The above is the small editorial to you to collate the knowledge of the relevant aspects of the belief that you should have an understanding of the situation, if the information used in the area of what are the medical products and what is not Understand, you can read other related articles of LifeCat, hope to bring you help.
