Abstract

The present invention relates to a preparation process of a modified chitosan composite gel moisture retention adhesive bandage, which comprises a nonwoven layer, a moisture retention layer and a protective layer from bottom to top, wherein the moisture retention layer consists of a modified chitosan gel. The preparation process designs the preparation method of the adhesive bandage. The adhesive bandage has the characteristics of bacteriostasis, inflammation relief, bleeding and pain stopping, and no wound adhesion, and provides a moist environment to accelerate wound healing, and mitigates the physic and spirit pain of the patients.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a preparation process of a modified chitosan composite gel moisturizing band-aid. Background technique [0002] With the improvement of people's living standards, people's requirements for the details of life are getting higher and higher, and they know how to enjoy life more and more. Minor traumas in life are inevitable. While people meet the basic medical security, they also put forward higher requirements for trauma care. Most of the existing band-aids are simple in structure, and only perform simple physical hemostasis and bandaging on the wound, which makes the wound easy to be infected, difficult to heal, and easy to leave scars. In addition, dry band-aids and dressings tend to stick to the wound when the wound is scarred and replaced, causing secondary injury to the patient, slowing down the healing process, and bringing mental pain and financial burden to the ...
