Problems solved by technology

[0002] There are many kinds of dressings used for hemostasis and sterilization in the prior art, but the hemostasis speed is often slow, and the hemostatic effect on large-area skin bleeding wounds is not good, which affects the actual effect on patient rescue
In addition, the bactericidal effect of medical dressings in the prior art is relatively single, and the bactericidal effect is not ideal, so it is particularly easy to cause wound suppuration and further infection
[0003] Chitosan has the effect of hemostasis and recovery of damaged skin, and is often used in medical dressings, but the hemostasis speed is slow when chitosan is used alone. In the prior art, some auxiliary reagents are also added to improve the hemostatic function, but the effect is often not good

Abstract

The invention belongs to the field of medical materials, and particularly discloses a haemostatic sterilizing dressing which comprises, by weight, 20-40 parts of chitosan, 5-10 parts of curcumin, 1-3parts of taurine, 0.5-1 part of sodium hyaluronate, 0.5-3 parts of menthol, 0.5-3 parts of nano-silver and 1-3 parts of ammonium dihydrogen phosphate. In addition, the invention further provides a preparation method of the dressing. Compared with the prior art, the dressing is high in haemostatic speed and has an excellent haemostatic effect on large-area skin bleeding wounds. The dressing is goodin sterilizing effects, particularly has excellent sterilizing effects on pyogenic cocci such as staphylococci and streptococci, and accordingly prevents wound suppuration fester or infection.
