Problems solved by technology

With the aging of the population and the increase in the number of people with diabetes, there are more and more chronic ulcer wounds, and wound dressings are becoming more and more important. However, there are many problems in the existing medical dressings, such as unstable antibacterial properties and difficult repair of damaged tissues. Slow, poor hemostatic effect, poor exudate absorption and other shortcomings, urgently need to be improved
Iodine is a broad-spectrum high-efficiency antibacterial and antiviral material, but iodine is insoluble in water, iodine and iodide have poor stability, and are easily volatile and sublimated when exposed to heat, light or alkali, so the application is relatively limited

Abstract

The invention discloses an antibacterial film and an antibacterial repairing dressing using the antibacterial film.According to formula matching, the antibacterial film is prepared from, by weight, 5-20% of chitosan-iodide composition, 5-20% of gelatin, 5-20% of a medical polymer material, 0.1-1% of glycerol, 0.1-1% of citric acid and 40-70% of deionized water.The antibacterial repairing dressing can effectively kill pathogenic bacteria within a large range, stop bleeding fast, repair damaged tissue and absorb seepage in quantity and is safe and convenient to use clinically.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular to an antibacterial repair dressing. Background technique [0002] Medical dressings can replace damaged skin for temporary protection, avoid or control wound infection, and provide conditions conducive to wound repair and healing. With the aging of the population and the increase in the number of people with diabetes, there are more and more chronic ulcer wounds, and wound dressings are becoming more and more important. However, there are many problems in the existing medical dressings, such as unstable antibacterial properties and difficult repair of damaged tissues. Slow, poor hemostatic effect, poor absorption of exudate and other shortcomings, urgently need to be improved. Iodine is a broad-spectrum high-efficiency antibacterial and antiviral material, but iodine is insoluble in water, iodine and iodide have poor stability, and are volatile and sublimated when exposed to heat...
