Preparation method of nanosilver-supported medical dressing

Abstract

The invention discloses a preparation method of a nanosilver-supported medical dressing. The nanosilver-supported medical dressing is prepared from the following components in parts by weight: 15 to 20 parts of polyester fiber, 30 to 40 parts of chitosan, 3 to 10 parts of lemon peel pectin, 12 to 20 parts of polyglycolic acid, 10 to 14 parts of didecyl dimethyl ammonium chloride, 3 to 10 parts ofpectin, 5 to 10 parts of sodium carboxymethylcellulose, 3 to 12 parts of alginate, 10 to 20 parts of zirconium phosphate-supported silver, 10 to 20 parts of nanosilver, 10 to 20 parts of nanoscale zinc oxide, 10 to 20 parts of honey, 5 to 8 parts of sodium dehydroacetate, 3 to 10 parts of molybdenum dithiocarbamate and 30 to 40 parts of water. The nanosilver-supported medical dressing prepared bythe method disclosed by the invention has the advantages of little irritation, no toxic and side effects, no relapse and good biocompatibility and antibacterial property.

Description

technical field [0001] The invention relates to a preparation method of a medical dressing loaded with nanometer silver. Background technique [0002] Difficulty in wound healing is a frequently encountered problem in plastic surgery. Clinically, the treatment of small wounds is mainly through active iodine disinfection, spraying human epidermal growth factor and other drugs, and finally covering with sterile gauze. For large wounds, skin grafts and skin flaps are mainly used. After surgical treatment, the surface is covered with Vaseline gauze, and finally covered with sterile gauze. Although the above treatment methods are relatively mature, there are still the following deficiencies: (1) it is difficult for the drug to maintain an effective concentration in the wound for a long time, and it cannot stably and continuously exert the drug effect; Degradability, need to be replaced every 3 days. Medical dressings are wound-wrapping supplies, medical materials used to cov...

AI Technical Summary

Problems solved by technology

Although the above treatment methods are relatively mature, there are still the following deficiencies: (1) it is difficult for the drug to maintain an effective concentration in the wound for a long time, and it cannot stably and continuously exert the drug effect; Degradability, needs to be replaced every 3 days

In the initial stage of wound formation, a large amount of wound exudate flows out. The existing dressings on the market can generally meet the needs of low to medium exudate, but it is difficult to meet the demand for wounds or wounds with high exudate

Existing dressings have relatively poor ductility, and in special parts such as buttocks and joints, often due to limited tensile strength, they cannot provide good comfort
