Preparation method of medical porcine or bovine pleura biological dressing

Abstract

The invention discloses a preparation method of a medical porcine or bovine pleura biological dressing, which comprises the following steps: (1) selecting healthy adult swine or cattle, slaughtering, and integrally taking down the parietal pleura; (2) removing the incidental fat from the pleura; (3) soaking to disinfect the pleura having the fat removed in a disinfection liquid, and rinsing out with sterile normal saline; and (4) under sterile working conditions, putting the disinfected and rinsed pleura into a medical plastic bag, adding a proper amount of skin storage liquid into the bag, and refrigerating for later use, wherein the product is preferably used within one week. The preparation method disclosed by the invention has a simple process, and raw materials can be easily acquiredfrom wide-range sources, so that the preparation method can be easily completed by grass-roots medical treatment units. The prepared pleura dressing is low in cost, is relatively stable in size specification and flexibility and has high transparency, thereby providing convenience for observing the change of a wound surface; the prepared pleura dressing has soft texture and good elasticity and randomness, has less reject reaction on the wound surface and can not cause the occupation problem; and the prepared pleura dressing can relieve the pain of the burning wound surface, reduce the exudation of the wound surface, protect the wound surface, promote the healing of the wound surface and lower the scar hyperplasia degree.

Description

technical field

[0001] The invention relates to a preparation method of a biological dressing for treating burns or wounds, in particular to a preparation method of a medical pig or bovine pleural biological dressing. Background technique

[0002] At present, in the field of medical burns and trauma, pigskin is the most used biological dressing for burn (wound) wounds, including irradiated pigskin, glutaraldehyde pigskin, etc., and animal peritoneum or bladder membrane are also often used as burn and wound dressings. Dressings for wound repair. Pigskin processing requires special equipment such as pigskin leather machines and various procedures, so the production cost of pigskin biological dressings is high, and the price of medical products is expensive; animal peritoneum or bladder membrane requires special processing techniques, the procedures are complicated, and the price is relatively high.
