Abstract

The invention discloses a hydrocolloid dressing and a preparation method thereof, and belongs to the technical field of medicine. The prepared modified graphene hydrophilic colloid compound can give full play to the excellent performance of graphene, the solubility is increased, the dispersibility of graphene in a matrix is improved, quaternary carboxyl with a negative charge in graphene oxide interacts with a quaternary ammonium ion with a positive charge in octadecyl trimethyl ammonium chloride through the ionic reaction, the dressing has the good roughness, and the structure is not prone todamage; in addition, the compound effect of sodium secondary alkyl sulfonate and octadecyl trimethyl ammonium chloride is good, and by means of the synergistic effect, the modified graphene hydrophilic colloid compound has the good dispersibility, the lasting stability and the like. Accordingly, the problems that some existing hydrocolloid dressings cannot effectively improve the absorptivity orimprove the antibacterial property or the like, and under more wound surface seepage, the problem that structures of the hydrocolloid dressings are likely to be destroyed is solved.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a hydrocolloid dressing and a preparation method thereof. Background technique [0002] The hydrocolloid dressing belongs to one of the products of medical biopolymer material preparation. Hydrocolloid dressings are dressings processed by mixing elastic polymeric hydrogels with synthetic rubber and viscose. The most common gel in the dressing is hydroxymethylcellulose, which can be firmly attached to the skin at the edge of the wound and can swell up to 12 times after absorbing the exudate. Hydrocolloid dressings are mainly used in the treatment of chronic wounds such as pressure ulcers and venous ulcer wounds. Pressure sores are a complication of long-term bedridden patients and a major problem in clinical nursing. Hydrocolloid dressings are often used to treat stage II-III pressure ulcers. Many clinical studies have shown that hydrocolloid dressings are superio...
