Liquid band-aid

Abstract

The invention provides a liquid band-aid. The liquid band-aid is composed of, by weight, 8-12 parts of PVB, 1-3 parts of PVP, 25-30 parts of ethanol, 53-65 parts of ethyl acetate and 0.5-2.0 parts of glycerin. The liquid band-aid has the advantages that the liquid band-aid can realize wet healing, isolation waterproofness and no scar generation; healing of a wound can be realized better by maintaining a wet environment in a slightly acidic environment, and hydrocolloid leakage is avoided even if the liquid band-aid is used for many days; granulation tissue is not damaged caused by the fact that a colloidal thin film is used for covering, intrusion of dirt and bacteria can be prevented, and the liquid band-aid is usable during bathing; the liquid band-aid can automatically distinguish tissue and selectively clean when being adhered to the wound.

Description

technical field [0001] The invention relates to a liquid band-aid, which belongs to the technical field of medical devices. Background technique [0002] Band-aids can compress and stop bleeding, protect wounds, prevent infection, and promote healing. At the same time, they have the advantages of small size, easy to use, easy to carry, good air permeability, and reliable curative effect. Band-aids have become the necessary sanitary articles for people's families at present. After decades of development, the types of Band-Aids have also been enriched, which can basically meet the needs of different groups of people. [0003] At present, traditional band-aids occupy the main market in the market, and the band-aids that are recognized by the masses are still the traditional band-aids that are easily accessible to daily people. Hospitals and pharmacies mainly sell traditional band-aids. The information about liquid band-aid is difficult to be understood by people, and most of ...

AI Technical Summary

Problems solved by technology

[0004] Traditional wound dressings have the following disadvantages: adhesion to the wound, causing mechanical re-injury when replaced, bleeding pain after dressing change; limited absorption capacity; not waterproof or waterproof and airtight; bacteria are easy to penetrate and easy to infect, and scabs hinder the healing of the wound Healing; limited area coverage and movable parts; frequent replacement, heavy dressing workload, easy to leave debris; severe dehydration on the wound surface, long wound healing time; non-degradable, although the volume is small, there is still waste garbage

In order to shorten the film-forming time, the liquid band-aid made by adding a large amount of alcohol-based organic solvents will have a strong tingling sensation during use, which makes patients feel scared and chooses to use traditional band-aids instead; it is made of water-soluble polymers Although the film material has excellent water absorption and swelling properties during preparation, it is not possible to add a large amount of easily volatile organic component solvents (compatibility contraindications) to shorten the film forming time (some even reach more than 10 minutes), because it cannot cater to the efficiency of patients seeking fast and convenient Awareness, so this will also greatly affect the likelihood of patients' willingness to accept the product
