Anti-infection medical film

Abstract

The invention discloses an anti-infection medical film, which comprises the following components in parts by weight: 45-55 parts of polyethylene, 12-20 parts of polyurethane, 10-14 parts of jellyfish collagen, and 3-8 parts of metronidazole 5-8 parts of polymethylene carbonate, 2-8 parts of ethylene glycol, 1-4 parts of sodium hexametaphosphate, 12-20 parts of chitosan lactate, 6-10 parts of calendula oil, Chuanxiong powder 14‑20 parts, panthenol 5‑8 parts, tea polyphenols 5‑10 parts, red peony powder 7‑11 parts. The anti-infection medical film of the present invention can effectively prevent wound infection, has good biocompatibility and tissue compatibility, no stimulation to tissues, good elasticity, good ventilation effect, little irritation to skin, and no harm to human body. Poison is harmless.

Description

Technical field [0001] The invention belongs to the field of biomedical materials, and specifically relates to an anti-infection medical film. Background technique [0002] Biomaterials are a class of high-tech materials used to diagnose, repair or enhance the functions of human tissues and organs, that is, natural or man-made materials used to replace and repair living tissues, and their action drugs cannot be replaced. Biological materials can perform, enhance or replace certain functions lost due to diseases, injuries, etc., but cannot restore defective parts. Since the late 1990s, the world's biomaterial science and technology have developed rapidly. Even in the current global economic downturn, biomaterials still maintain a high-speed growth of 13% per year, which fully reflects their strong vitality and broad development prospects. Modern medicine is developing in the direction of regeneration and reconstruction of damaged human tissues and organs, restoration and enhancem...
