Silver-containing medical hydrocolloid dressing and preparation method thereof

Abstract

The invention belongs to the technical field of medical and sanitary auxiliary materials and particularly relates to a silver-containing medical hydrocolloid dressing and a preparation method thereof.The hydrocolloid dressing includes CMC/PEG/PAA particles, thermoplastic rubber, liquid paraffin, tackifying resin, a plasticizer, alpha-cyclodextrin polyrotaxane/silver sulfadiazine serving as an antibacterial agent and the like. In general, by optimizing and adjusting relevant components, the hydrocolloid dressing which is safe, free of irritation, uniform in liquid absorption, excellent in antibacterial performance and lasting in antibacterial effect is prepared, and the antibacterial agent is uniformly dispersed. The dressing is great in waterproof and antibacterial performance and capableof absorbing a large amount of exudate and toxic substances of a wound and maintaining a wet healing environment for the wound for a long time without being bonded to the wound and has other excellent performance. Therefore, the dressing has a high practical value for wound repairing 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
