[0005] In surgical operations such as lower extremity surgery and cardiac surgery to remove the great saphenous vein, it is necessary to ensure that the patient's limbs are sterile to prevent germs from affecting the operation. However, it is inconvenient to disinfect the patient's feet, and the disinfection effect of the feet is not good. , easy to remain bacteria and germs, etc., the actual treatment after disinfection is to use sterile dressings to bandage the patient's hands or feet. Not strong, short service life, poor mechanical properties, can not meet the current use requirements

Abstract
The invention discloses a sterile rubber foot cover for surgery. The foot cover is prepared from, by weight, 30-40 parts of silicone rubber, 25-40 parts of epichlorohydrin rubber, 5-13 parts of stearic acid, 10-15 parts of paroline, 1-6 parts of titanium dioxide, 3-12 parts of anti-ageing agent, 1-10 parts of accelerant, 2-9 parts of di-n-octyl phthalate, 5-10 parts of carbon black, 5-10 parts ofzinc oxide, 0.25-0.75 part of polyethylene glycol PEG4000, 1-5 parts of coagent and 1-5 parts of plasticizer. The foot cover is simple in formula, diversified in function, not prone to bacteria breeding and low in cost, the raw materials are diversified, the service life of the rubber foot cover can be effectively prolonged, various mechanical indexes are all excellent, and the current use requirements are met.
Description
technical field [0001] The invention relates to a medical appliance, in particular to a sterile rubber foot cover for operation. Background technique [0002] Surgery refers to the treatment such as excision, suture and other treatment performed by doctors on the patient's body with medical equipment. The operation performed on the human body with knives, scissors, needles and other instruments to maintain the health of patients. It is the main treatment method of surgery, commonly known as "surgery". The purpose is to treat or diagnose diseases, such as removing diseased tissue, repairing damage, transplanting organs, improving the function and shape of the body, etc. Early operations were limited to simple manual methods of cutting, cutting, and suturing on the body surface, such as abscess drainage, tumor resection, and trauma suture. Surgery is thus an operation that destroys the integrity of tissue (incision) or restores tissue whose integrity has been compromised (s...
