Liquid dressing

Abstract

The invention discloses a liquid dressing. A formula of the liquid dressing contains the following components in parts by weight: 140-160 parts of a polyvinyl alcohol water solution, 7-9 parts of an acrylate emulsion pressure-sensitive adhesive, 1.8-2.2 parts of glycerol, 0.4-0.6 part of calcium chloride, 0.5-0.7 part of trisodium glycyrrhizinate and 0.15-0.25 part of potassium sorbate, wherein the concentration of the polyvinyl alcohol water solution is 12%, the polymerization degree of polyvinyl alcohol is 1800, and the alcoholysis degree is 99.9%; the solid content of the acrylate emulsionpressure-sensitive adhesive is 53.0%, and the viscosity is 2100Pa.s; and glycerol is analytically pure. By rising the mouth through the liquid dressing or coating a mouth sore with the liquid dressing, the liquid dressing can automatically harden into a film so as to play roles of isolation and protection within a certain period of time and is moderate in hardness, the flexibility and the onset time are simultaneously considered, and the liquid dressing has an excellent assistance effect to the healing of the sore; and in a storage process, the medicinal materials have stable property and areunlikely to deteriorate, and the liquid dressing does not need to be shaken for a long time, so that the convenience is brought to users.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a liquid dressing. Background technique [0002] Dressings are medical devices that are placed over skin lesions to temporarily function as a skin barrier until the permanent skin barrier is rebuilt. Traditionally, a dry environment reduces the chance of infection. Therefore, a dry environment should be created for the wound as much as possible to facilitate wound healing. Therefore, traditionally the most used dressings are gauze and non-woven fabrics. The dressing has good air permeability, can fully keep the wound dry, and has the advantages of protecting the wound surface, simple application, and cheap price. But its shortcomings are also very prominent: (1) the barrier effect is poor; (2) the granulation tissue on the wound surface is easy to grow into the mesh of the gauze, which will damage the new tissue and cause pain when changing the dressing; (3) there is ...
