Abstract
The invention discloses a larva chrysomyiae liquid wound dressing and a preparation method thereof. The larva chrysomyiae liquid wound dressing is prepared from 15-70 parts of traditional Chinese medicine larva chrysomyiae, 30-80 parts of a polyvinyl alcohol film forming material, 0.5-10 parts of a dibutyl phthalate plasticizer, 0.5-10 parts of glycerinum and 1-5 parts of laurocapram. The preparation method comprises the steps that after the polyvinyl alcohol and ethyl alcohol are stirred to be dissolved, the laurocapram, the glycerinum and the dibutyl phthalate are added, a film solution is prepared, larva chrysomyiae is added into the film solution, the materials are mixed to be uniform, and then the larva chrysomyiae liquid wound dressing is prepared. The larva chrysomyiae liquid wound dressing has the effects of fighting bacteria, eliminating inflammations, promoting wound healing and the like and has the advantages that the breathability and the water-resisting property are good, no anaphylactic reaction or drug resistance is generated, and the wound dressing is not limited by the size and the shape of the wound. The larva chrysomyiae liquid wound dressing and the preparation method thereof are good in application prospect.
Description
technical field [0001] The invention relates to a grain worm liquid wound dressing and a preparation method thereof, which is a medical dressing and belongs to the field of medical technology. Background technique [0002] The skin is the most widely covered organ of the human body. Skin trauma is inevitable in daily life and work. Ordinary bandages can compress and stop bleeding, protect wounds, and prevent infection. They also have the advantages of small size, easy use, and portability. The adhesive plaster used in the band-aid has poor air permeability, and the water vapor and sweat normally secreted by the human body cannot penetrate this layer of adhesive tape, which is easy to breed bacteria and cause or aggravate infection; secondly, water and bacteria can easily infiltrate the wound from the edge of the adhesive tape, leading to wound infection; , most bandages have a fixed size and size, and are not suitable for wounds of all shapes and sizes. At present, the drug...
