Abstract

The invention provides hydrocolloid dressing and a preparation method thereof. The hydrocolloid dressing at least comprises backlining, hydrocolloid and a stripping layer, wherein the hydrocolloid is arranged on the backlining; the stripping layer is arranged on the hydrocolloid; the hydrocolloid comprises the following components in percentage by mass: 30 to 50 percent of polyisobutene, 15 to 25 percent of polycationic compound, 15 to 20 percent of polyanionic compound and 10 to 35 percent of neutral polymer; the polycationic compound consists of at least one of chitosan salt and diethyl amino ethyl glucan; the polyanionic compound consists of at least one of pectin, sodium carboxymethylcellulose, sodium alginate, carrageenin and xanthan gum; and the neutral polymer consists of at least one of gelatin, locust bean gum and guar gum. The hydrocolloid dressing can form a wet healing environment at the wound position, has a good wound healing effect and excellent water absorbency and stability, is suitable for high-leachability wounds, has excellent softness and autohension, and is convenient to use.

Description

technical field [0001] The invention relates to a dressing and a preparation method thereof, in particular to a hydrocolloid dressing and a preparation method thereof. Background technique [0002] The hydrocolloid dressing should have the following characteristics: (1) It can absorb a large amount of exudate and toxic substances, and can maintain a certain shape and strength when wet; (2) It can maintain sufficient humidity in the wound and have better antibacterial properties. (3) There is no damage to the wound when changing the dressing; (4) Good storage stability and degradability, the waste of the hydrocolloid dressing does not pollute the environment. Hydrocolloid dressings have been widely used in medical supplies, especially dressings, due to their ability to create a moist healing environment and the nature of their semipermeable membranes. Compared with traditional dressings, dressings made of hydrocolloids have the following advantages: faster healing, easy oper...
