Medical membrane with function of easing pain and preparation method of medical membrane

Abstract

The invention relates to the technical field of medical supplies, and in particular relates to a medical membrane with the function of easing pain and a preparation method of the medical membrane. Themedical membrane is prepared from the following raw materials in parts by weight: 50-70 parts of carboxymethyl chitosan, 25-45 parts of sodium carboxymethyl cellulose, 5-8 parts of polylactic acid, 20-40 parts of polyvinyl alcohol, 10-35 parts of hyaluronic acid, 10-20 parts of silk fibroin, 12-16 parts of gelatin, 8-12 parts of borneol, 6-10 parts of flos carthami, 8-14 parts of cortex mori, 4.6-8.2 parts of all-grass of Cynanchum komarovii Al., 3.1-6.2 parts of licorice root, and 2-6 parts of cassava starch. The prepared medical membrane effectively enhances the pain easing effect for the wound, has a good pain easing effect, can effectively alleviate the pain of a patient, provides a moist heal environment for the wound, and promote the heal of the surface of the wound. The prepared medical membrane has good biocompatibility, is free of irritation to the skin and the tissue, can be softly applied to the surface of the skin, and can be widely applied to the field of medical treatment.
