Problems solved by technology

Although the EGF hydrocolloid dressing described in the invention has a wide range of applications and is applicable to the nursing of multiple skin wounds, the microcapsules are microcapsules that will slowly break down above 30°C. When the temperature is higher, It will affect the stability of the hydrocolloid dressing, thereby affecting the effect of use
[0006] At present, there are many types of hydrocolloid functional dressings on the market, but most of them have single functions and unsatisfactory performance

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to a multifunctional hydrocolloid dressing and a preparation method thereof. Background technique [0002] Human skin can maintain the stability of the internal environment of the human body, prevent it from being damaged more and prevent the invasion of microorganisms. When the skin is injured and the normal function is damaged, medical dressings can protect the human body and avoid injury. Until the skin recovers, a well-performing wound covering can temporarily act as a barrier function, providing a favorable microenvironment for wound healing. In wound healing, dressings can be used to cover the wound. [0003] The representative of traditional dressing is gauze. Gauze is an inert dressing made from cotton, linen, and burlap. Although this kind of dressing has the advantages of protecting the wound surface, good absorption, cheap price, simple productio...
