Description

Composite polypropylene melt-blown fabric dressing

Technical Field

The utility model relates to a medical material technical field particularly, relates to a compound polypropylene melt-blown fabric dressing.

Background

The main component of the alginate medical dressing is alginate, which is natural polysaccharide carbohydrate extracted from seaweed and is natural cellulose. The medical dressing can form soft gel after contacting wound exudate, provide an ideal moist environment for wound healing, promote wound healing, relieve wound pain and reduce scar formation. Meanwhile, the gel has the advantages of safety, no toxicity, high hygroscopicity, hemostatic property and gelling property. The existing alginate fiber dressing is simple and crude in preparation method, water-insoluble alginate is obtained mainly by crosslinking a sodium alginate aqueous solution and a solution containing calcium ions or strontium ions, the alginate is washed and then crushed into alginate short fiber material, and the alginate short fiber material is formed by pressing and the like. The alginate fiber dressing prepared in this way has disordered internal structure, and the porosity and the fiber shape can not be controlled. When the porosity is too small, the amount of liquid which can be locked is reduced; when the porosity is too high, harmful substances such as bacteria from the outside may be able to penetrate the dressing into the wound.
