Abstract

The invention discloses a medical dressing of a Shuanghuanglian form-stable hydrogel and a preparation method thereof. The medical dressing of the Shuanghuanglian form-stable hydrogel is formed by laminating of two layers of materials, one layer is formed by subbottom mounting material, and the other layer comprises: Shuanghuanglian extract, polyoxygen enol, polyoxyethylene, glycerol and water. The preparation method of the medical dressing comprises the following steps: weighing the Shuanghuanglian extract, and dissolving the Shuanghuanglian extract in water, adding the polyoxygen enol, stirring to lead the mixture to swell, then adding the glycerol, stirring to lead the polyoxygen enol to be dissolved, adding the polyoxyethylene after cooling, stirring and dissolving, degassing in vacuum, and coating the mixture on the subbottom mounting material by transitivity, thus obtaining the medical dressing of the Shuanghuanglian form-stable hydrogel. The medical dressing is stuck on the diseased parts of patients, has no toxicity, nonirritant, no irritability and no stripping response, as well as functions of high hygroscopicity, deodorization, water resistance and the like simultaneously.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, in particular to a Shuanghuanglian shaped hydrogel medicinal dressing, and also relates to a preparation method of the medicinal dressing. Background technique [0002] Shuanghuanglian is an extract extracted from traditional Chinese medicines Shuanghua, Huangling and Forsythia that have been widely used in clinical practice. , but there is no preparation of Shuanghuanglian extract into medicinal dressings. Contents of the invention [0003] The purpose of the present invention is to provide a Shuanghuanglian shaped hydrogel medicinal dressing, the main drug Shuanghuanglian extract is dispersed in the matrix to make a medicinal dressing. Release volatile antibacterial effect to achieve the purpose of treatment, and the base backing material exerts its high hygroscopicity, deodorization and water resistance, and plays the role of skin barrier. [0004] Another object of the present i...
