Water gel woundplast containing American cockroach active ingredients

Abstract

The invention provides water gel woundplast containing American cockroach active ingredients. The water gel woundplast comprises a water gel layer and a high-elasticity base body layer, wherein the water gel layer achieves a healing effect and is in contact with the skin. The water gel woundplast is characterized in that the water gel layer is prepared from the following ingredients in parts by mass: 1 to 3 parts of American cockroach extracts, 1 to 2 parts of bletilla extracts, 1 to 3 parts of chitosan hydrochloride, 1 to 4 parts of polyvinylpyrrolidone K30, 0.05 to 0.1 part of HPMC10W, 0.5 to 1.5 parts of PVA-17880, 1 to 3 parts of glycerol and 20 to 30 parts of pure water. In the contact process of the water gel woundplast with the skin, the water gel layer has the effects of inhibitingbacteria, diminishing swelling, relieving pain and prompting skin healing through the American cockroach extracts and the bletilla extracts; meanwhile, through the chitosan hydrochloride loaded withantibacterial materials with high biocompatibility, the antibacterial and bleeding stopping effects are further improved; the healing time is shortened; the medicine dwell time is prolonged; the wounded surface can better absorb the medicine; the skin tissue restoration is accelerated; the wound healing and regeneration rate is improved; meanwhile, the good waterproof effect and skin-friendly comfort are realized.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a hydrogel band-aid containing an active ingredient of Periplaneta americana and a preparation method thereof. Background technique [0002] The American cockroach (Periplaneta americana L.) belongs to the class Insecta, the order Blatella, the suborder Blatella, and the genus Periplaneta. one. At present, scholars at home and abroad have more and more researches on Periplaneta americana, and found that it has anti-tumor, anti-virus, detumescence, repair, very significant anti-inflammatory activity, and good inflammation inhibition rate. [0003] Bletilla striata is the dry tuber of Bletilla striata, a common traditional Chinese medicine with high medicinal value. It has the functions of astringent and hemostasis, clearing away heat and dampness, reducing swelling and promoting muscle growth, antibacterial, promoting wound healing, and resisting chapped skin...

AI Technical Summary

Problems solved by technology

[0005] The daily band-aid preparation process mostly uses paper cloth as the carrier, and the base has poor waterproof performance and no high ductility. Among the users, most of the wounds are infected because the band-aid is not waterproof and the wound is wet, leaving scars

The movement of wounds in the joints is limited due to the poor elasticity of the paper cloth as the carrier matrix, and the rest of the external medicines are mostly ointments and liniments, which are inconvenient to administer
