Multifunctional liquid dressing and preparation method thereof

Abstract

The invention relates to the field of medicinal dressings and in particular relates to a multifunctional liquid dressing and a preparation method thereof. The multifunctional liquid dressing comprises the following components in parts by mass: 2-8 parts of polyvinyl butyral, 0.5-0.8 part of sodium alginate-polyvinylpyrrolidone, 0.2-0.6 part of nano-silver-chitosan, 0.1-0.4 part of sodium carboxymethylcellulose, 0.1-0.4 part of carrageenan, 0.1-0.4 part of menthol and 91-97 parts of absolute ethyl alcohol. The multifunctional liquid dressing disclosed by the invention is waterproof, breathable and visible in wound, can prevent infection and contributes to wound healing.

Description

technical field [0001] The invention relates to the field of medical auxiliary materials, in particular to a multifunctional liquid dressing and a preparation method thereof. Background technique [0002] When the skin is injured somewhere and a wound occurs, it is necessary to stop bleeding and disinfect in time, apply ointment, and at the same time isolate bacterial contamination in the environment through medical accessories. Existing medical dressing bonding layer is generally coated with binding agent, generally after ointment is smeared on wound surface during use, covers one deck gauze again, fixes with dressing then. [0003] On the one hand, because the gauze is opaque, the wound is invisible, and the healing of the wound cannot be checked in time. If the gauze is not covered, it will cause the ointment to be squeezed, causing the adhesive layer to lose its cohesive force after the ointment sticks around it, and cannot be firmly and airtight. Adhesive to the skin, ...

AI Technical Summary

Problems solved by technology

[0003] On the one hand, because the gauze is opaque, the wound is invisible, and the healing of the wound cannot be checked in time. If the gauze is not covered, it will cause the ointment to be squeezed, causing the adhesive layer to lose its cohesive force after the ointment sticks around it, and cannot be firmly and airtight. Adhesive to the skin, affecting wound healing

The second aspect, sticking to the wound, will cause mechanical damage again when replacing

The third aspect is that if it is not waterproof, water will easily enter the wound dressing, causing infection, which will easily affect the recovery effect and even aggravate the condition

The fourth aspect is airtight, which is not conducive to wound healing

Fifth aspect, microbes in the external environment are easy to pass through, and the chance of cross-infection is higher

In the sixth aspect, the wound is wrapped with a gauze, which affects the appearance
