Problems solved by technology

Among them, glutaraldehyde pigskin is chemically sterilized with glutaraldehyde, which is likely to cause harmful chemical residues; irradiated pigskin uses cobalt 60 The gamma-ray irradiation disinfection of traditional Chinese medicine takes a long time, and it takes several hours to tens of hours, which is easy to destroy the activity and structure of the skin, and the cost is high
The above-mentioned medical pigskins have no anti-infection properties, so their clinical application has certain limitations, especially for some infected burn wounds, it is not suitable for application
Furthermore, the wound adhesion time of general medical pigskin is not long, and there is a more obvious rejection reaction
In addition, general medical pigskin is not easy to preserve

Embodiment 1

[0015] Embodiment one: the manufacture method of medical pigskin of the present invention comprises the following steps:

[0016] a. Raw material preparation: Select healthy staple food pigs under 4 months old and under 45 kg. After slaughtering and bleeding, do not soak in boiling water, but directly chop off the pigskin of the required parts, scrape off the pig hair, remove fat. Then use an electric skin splitter to split pigskin slices with a thickness of 1±0.2mm and leather, and wash them for later use;

[0017] b. Soaking in normal saline: take 0.9% sodium chloride solution, place the cleaned skin in a stainless steel container, and soak for 30 minutes;

[0018] c. Dehydration: the skin in the sodium chloride solution is placed in a stainless steel dehydrator for dehydration, and the water content is controlled within the scope of 25 ± 5%;

[0019] d. Soaking in cerium nitrate solution: make 0.5% aqueous solution of cerium nitrate, soak the dehydrated pigskin slices in ...

Abstract

The production method of medical pork skin includes the following steps: a. raw material preparation; b. soaking the raw material in physiological salt solution; c. dewatering; d. soaking in cerium nitrate solution; e. double-layer vacuum packaging; f. using electronic uccelerator to make irradiation and disinfection; and g. freezing, putting into storage. Said invention adopts the cerium nitrate solution and electronic accelerator irradiation and disinfection, so that it raises the sterilizing disinfection effect of pork skin, raises its anti-infective power, and can delay repellency and can prevent growth of bacteria, and can shorten wound healing time, therefore it can obtain good effect in clinical application.

Description

technical field [0001] The invention relates to a method for manufacturing biological dressing medical pigskin, which belongs to the field of manufacturing technology of special medical dressing animal skin. Background technique [0002] Burns and other wounds caused by various reasons make the human skin form a wound surface in direct contact with the outside world, and wound treatment is the key to the success of wound treatment. Medical pigskin is a kind of biological tissue material, which can reduce the exudation of wound liquid, limit the loss of protein, and protect the new wound tissue by maintaining the temperature and humidity necessary for the growth of wound tissue cells after covering the wound surface. Conducive to wound healing. At present, the medical pigskins used in China mainly include fresh pigskin, refrigerated pigskin, glutaraldehyde pigskin, and irradiated pigskin. Among them, glutaraldehyde pigskin is chemically sterilized with glutaraldehyde, which...
