Making method of and use of antibiotic surgical dressing

Abstract

An antibacterial medical dressing for the operation wound is prepared from chitosan fibers through alkalizing to become alkaline chitosan fibers, and etherifying reaction on chloroacetic acid to become carboxymethyl chitosan fibers. When said fibers are encountered with water, it is swelling to become elastic gel. It is possible to add additive for higher curative effect.

Description

technical field

[0001] The invention relates to a medical dressing, in particular to a medical dressing containing carboxymethyl chitosan fiber. Background technique

[0002] For a long time, surgical dressings are mainly sterilized cotton and cotton gauze, which have certain limitations in their application. Cotton gauze itself does not have the ability to resist the reproduction of microorganisms. Although it has been sterilized, it is easy to be infected with bacteria during use. These traditional dressings will adhere to the wound during use, and even grow in the new granulation, causing pain to the patient and the generation of new wounds during dressing replacement.
