The middle part of the top sheet or the water absorption layer is provided with a hydrocolloid dressing. Hydrocolloid dressings are those made by processing a mixture of an elastic polymeric hydrogel with synthetic rubber and an adhesive. The most common gel in dressings is hydroxymethyl cellulose, which adheres firmly to the skin at the wound margin and expands 12 times when imbibed with exudate. Hydrocolloid dressings have the following properties: 1. has the ability of absorbing wound exudate. After imbibing exudate, the hydrophilic particles in the dressing can form a gel-like semisolid substance which is attached to the base of a wound to provide and maintain a wet environment which is beneficial to wound healing. 2. Has viscosity, and can form closed wound surface. The closed healing environment can promote the proliferation of capillary vessels and the formation of granulation tissues, thereby accelerating the healing of the wound surface. 3. Can play the function of debridement. On the one hand, the hydrocolloid contains endogenous enzymes and can promote the dissolution of fibrin; on the other hand, the closed environment provided by the hydrocolloid dressing is beneficial to macrophage to remove necrotic tissues. Hydrocolloid dressings are a new type of wound dressing developed under the guidance of the principle of wet healing. The hydrocolloid dressing can be applied to the treatment of various wounds, and particularly has obvious curative effect on chronic and refractory wounds. The absorbency, viscosity, etc. of hydrocolloids make them essential for ideal dressings, i.e. to protect the wound, provide a suitable environment to promote wound healing and to be easily removed without damaging the new tissue. Hydrocolloid dressings, of course, still have room for re-development, such as improved absorption and enhanced antimicrobial capacity.
