A kind of silver-containing medical hydrocolloid dressing and preparation method thereof

Abstract

This application belongs to the technical field of medical and health auxiliary materials, and specifically relates to a patent application for a silver-containing medical hydrocolloid dressing and a preparation method thereof. The components of the hydrocolloid dressing include: CMC / PEG / PAA particles, thermoplastic rubber, liquid paraffin, tackifying resin, plasticizer, antibacterial agent α-cyclodextrin polyrotaxane / silver sulfadiazine and the like. In general, the application has prepared a hydrocolloid dressing that is safe and non-irritating, has uniform liquid absorption, uniform dispersion of bacteriostatic agents, excellent bacteriostatic performance and long-lasting bacteriostasis through optimization and adjustment of related components, and The dressing has good waterproof and antibacterial properties, absorbs wound exudate and toxic substances in a large amount, can maintain a moist wound healing environment for a long time, and has excellent properties such as non-adhesive wounds, so it has good practical value for wound repair and wound healing.

Description

technical field [0001] This application belongs to the technical field of medical and health auxiliary materials, and specifically relates to a patent application for a silver-containing medical hydrocolloid dressing and a preparation method thereof. Background technique [0002] The skin is the largest organ of the human body. It has important functions such as resisting the invasion of external microorganisms, excreting and preventing water evaporation, regulating body temperature, and maintaining the stability of the internal environment of the body. To avoid further deterioration, functional band-aids are the most commonly used wound aids. [0003] In the prior art, new water-based dressings have developed rapidly in recent years because of their advantages such as convenient use, no limitation of wound size, and strong functionality. Aqueous dressings can directly adhere to wounds because they contain certain viscous components, so they have good application prospects ...

Problems solved by technology

However, in the silver-loaded microspheres prepared by this patent, the external carrier is a hydrophilic substance, while the hydrocolloid dressing matrix styrene-isoprene-styrene block copolymer is a hydrophobic substance, and there are hydrophilic substances in the preparation process. Agglomeration and uneven dispersion of water microspheres in the hydrophobic matrix, resulting in uneven absorption of exudate and antibacterial properties of the hydrocolloid, which in turn affects the actual use of the hydrocolloid
