1. Artificial organ membranes and medical devices. Polyether-type segmented polyurethane by the excellent hydrolytic stability, blood compatibility
good, and its strength is better than silicone rubber, so in the medical elastomers in the dominant position. Such as blood pump (artificial heart) and artificial
vessels. Heart aid heart bypass, artificial kidney osmotic folding membrane, artificial ventricle, artificial heart valves, diagnostic and therapeutic catheters; cardiac pacemaker.
2. Artificial skin and prosthetics. TPU soft foam is not only elastic and breathable, suitable for the production of artificial skin, this kind of human
Industrial skin can promote the growth of the human body's own skin. Such as the British Smith and 'Nephew company trade name OP-site polyurethane dressing film, can be used for burns, skin grafting, bedsores cover, surgical cover film, and blood transfusion, infusion, and through the fold and other needles, catheters, fixed and covered, and so on. Polyurethane has a good flexure, is the ideal material for lightweight and durable prosthesis which is the first to escape in modern times.
3. Fracture reduction and fixation materials. The human body fracture treatment should be fixed after the reset, previously used plaster bandage. This traditional method, although it has the advantages of extrusion, simple, but due to the plaster weight, low strength, poor permeability, water resistance, the skin has a favorable radical
role, impermeable stone rays, which not only gives the doctor to fix the operation of many inconveniences, but also to the patient to cause intolerable
pain. The orthopedic bandage made of polyurethane is strong, light, has good air permeability and water resistance, fast curing,
easy to operate, z-ray transmission is good, so it is used on the fracture disease ^ Phillip's position of the treatment of the fixation of the fracture, not only to greatly reduce the patient's
pain, and orthopedic surgeons easy to operate, can be in the z-ray irradiation of reset fixation and ruthenium in the case of not dismantling the bandage.
Checking the fixation and fracture healing at any time without removing the bandage improves the therapeutic effect.
