Problems solved by technology

Invention patent 92105926.4 provides a scientific preparation method for supplying biological dressings with irradiated pig skin, but it is only limited to the production of medical pig epidermis, and the pig dermis in the lower layer of the pig epidermis is useless because the original ecological pig dermis evaporates The quantity is large and cannot meet the requirements of biological dressings

Embodiment

[0009] Embodiment: a preparation method of irradiated oily pig dermis, comprising the following steps;

[0010] 1) Choose 60-80 kg healthy white pigs that have been confirmed by quarantine inspection, kill them alive, shave their hair, and then peel the skin to remove fat;

[0011] 2) Cut the pigskin into 200cm 2 ~1600cm 2 The skin slices are peeled off the epidermis to obtain pig dermis, and the peeled off epidermis is processed into medical burn wound dressings;

[0012] 3) splitting the pig dermis peeled off the epidermis into pig dermis sheets with a thickness of 0.6 to 0.8 mm with a commercially available electric skin splitter;

[0013] 4) Clean the pig dermis slices with sterile water and soak them in compound silver fluoride solution for 13-14 hours;

[0014] 5) Then transfer to five butter and soak for 12-13 hours;

[0015] 6) put the above-mentioned processed pig dermis sheet into a light-tight plastic bag and seal it;

[0016] 7) Irradiate with cobalt 60 for 17...

Abstract

The invention relates to a method for preparing the radiation oil pig leather, which comprises that cutting the white pigskin into the sheets at 200-1600cm2, removing the surface to obtain the pig leather; cutting into the pig leather sheets at 0.3-1.2mm thickness; washing with germ-free water to be arranged into composite fluorine silver solution to be immerged for 12-16h, then immerging it in butter for 10-15h; packing into light-tight plastic bag to be sealed and packed; radiating via cobalt for 15-20h; storing in refrigerator at 0--20Deg. C. before use, the radiation oil pig leather should be immerged by the warm water at 40Deg. C, then to be taken off and used. The invention can use waste pig leather to obtain 2-4 pig leather sheets, to be radiated by oil to reach the biological standards as radiation fluorine silver pigskin sheets, to reduce cost and save resource.

Description

technical field [0001] The invention relates to a preparation method of an external dressing for surgical treatment of burn wounds, in particular to a preparation method of irradiated oily pig dermis. Background technique [0002] Early skin grafting to treat burn wounds is the key to rescuing burn patients. Due to the lack of autologous skin sources, allogeneic skin has to be used, but the source of allogeneic skin is also very difficult. Since Bromberg reported the use of pigskin to cover deep wounds in 1965, domestic medical and surgical circles have carried out a large number of researches and clinical practices on using pigskin as a biological dressing to treat burn patients, and it is believed that pigskin covering burn wounds has better curative effect than artificial synthetic skin , Pigskin is a heterogeneous skin that is being promoted and used to treat burn wounds. Invention patent 92105926.4 provides a scientific preparation method for the supply of irradiated p...
