Liquid band-aid and preparation method thereof

Abstract

The invention relates to the field of medical dressings, in particular to a liquid band-aid, which comprises butyl acetate, benzyl alcohol, ethyl acetate, nitrocellulose, propylene glycol, polyethylene glycol, tocopheryl acetate and lipidosome, and the lipidosome comprises cytokines, antibacterial nanoparticles, an activity protective agent and phospholipid. Wherein the cell factors comprise one or two of EGF and FGF; wherein the antibacterial nano particles comprise nano silver; wherein the activity protective agent comprises one or two of tetrahydropyrimidine and trehalose; wherein the phospholipid comprises one or more of soybean lecithin, hydrogenated soybean phospholipid, dilauroyl lecithin and distearoyl phosphatidyl glycerol; the invention further discloses a method for preparing the liquid band-aid. The liquid band-aid is moderate in viscosity and not prone to falling off, and a wound cannot be torn off when the liquid band-aid is taken down; the liquid band-aid has good isolation and bactericidal properties, and can fundamentally realize rapid repair of skin injury.

Description

technical field [0001] The invention relates to the field of medical dressings, in particular to a liquid band-aid and a preparation method thereof. Background technique [0002] In daily life, situations of skin injury are unavoidable, such as daily cuts, burns and abrasions. Wound repair is a complex process involving multi-cells and multi-cytokines. The use of wound dressings plays an important role in the treatment or repair of wounds. It is beneficial to protect wounds from external aggressions, including physical contact injuries and microorganisms such as bacteria. re-infection, and then use the body's own healing and repair ability to wait for the wound to heal. [0003] Traditional Band-Aid is currently the most commonly used wound dressing, widely used in the treatment of small wounds on the human body, but it has many disadvantages, such as poor adhesion, poor air permeability, and easy to cause whitening of the skin near the wound, which makes the liquid Band-Ai...

AI Technical Summary

Problems solved by technology

[0005] 1. The film forming speed is slow. When the liquid band-aid is sprayed on the patient's wound, it needs to wait for 3-5 minutes;

[0006] 2. It is highly irritating to the skin but cannot completely sterilize the wound;

[0007] 3. After use, melanin deposits appear on the skin, and the skin repair speed is slow and the effect is poor;

[0008] 4. The viscosity is difficult to control. When the viscosity is too high, it is easy to cause mechanical re-damage during replacement; if the viscosity is too small, it is easy to leave the affected area

However, a technical solution for a liquid band-aid that has fast film-forming speed, moderate viscosity, good bactericidal properties, and can selectively and quickly repair skin damage has not yet been proposed.
