Embodiment 1

[0014] Example 1: After a healthy adult pig (cattle) is slaughtered, the chest and abdomen cavity is cut open along the midline of the chest and abdomen wall, the heart and lungs are removed, and then the chest wall is washed with clean water; the left and right parietal pleura are completely removed by hand or with a surgical knife Next, in order not to break the pleura, a little fat may be attached when peeling off the pleura, and the pleura area is measured after the pleura is flattened; after the pleura on both sides is completely removed, the fat is separated from the pleura with bare hands, and the size can be made about 15cm×30cm Two complete pleura; sterilize the pleura in 0.3% povidone iodine solution by mass for 30 minutes, wash it with sterile normal saline, put it in a medical plastic bag under aseptic conditions, and place it for 4~ Store in the refrigerator at 7°C for later use (use within one week).

Embodiment 2

[0016] Example 2: According to the method in Example 1, two complete pleura of about 15 cm × 30 cm were obtained; the pleura was put into 0.6% iodophor solution for disinfection for 15 minutes, and then rinsed with sterile physiological saline; After soaking in the skin storage solution, put it in a refrigerator at 4-7°C for 1 hour. Wherein the skin storage solution is: 4°C physiological saline containing 400,000 units / 500ml of penicillin, and the ratio of the soaked pleura area to the skin storage solution is 2cm2 / ml.

[0017] In a female patient with burns, the middle-thickness skin of the right thigh was taken, 2% of the area. After rewarming the pleural dressing prepared in Example 2 with 40°C normal saline, it was fully stretched, with the inner surface of the pleural dressing facing the wound, and spread on the taken For wounds behind the skin, cover with pleural dressings and cover about 2-3cm beyond the edge of the wound, and wrap them with sterile dressings. 48 hours...

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. Contents of the invention [0003] The technical problem to be solved by the...
