Embodiment 1

[0028] A method for preparing high-performance medical liquid band-aids includes the following specific steps:

[0029] (1) Add 1.0g cellulose acetate, 0.2g castor oil, 0.4g triacetin, 2.0g benzyl alcohol to 10.0g ethyl acetate solution, and mechanically stir to fully dissolve into a film-forming solution;

[0030] (2) Mix 2.0 mL of tannic acid ethanol solution (2.0 mg / mL) with 0.7 mL of silver nitrate aqueous solution (0.1 mg / mL), and react in a constant temperature water bath at 30°C for 8 hours to prepare a silver nanoparticle solution;

[0031] (3) The silver nanoparticle solution prepared in step (2) and 0.02 g of dopamine are added to the film-forming solution prepared in step (1) and mixed uniformly to prepare the high-performance medical liquid band-aid.

Embodiment 2

[0033] A method for preparing high-performance medical liquid band-aids includes the following specific steps:

[0034] (1) Add 1.2 g of cellulose acetate, 0.4 g of castor oil, 0.5 g of triacetin, and 4.0 g of benzyl alcohol to 12.0 g of ethyl acetate solution and fully dissolve it into a film-forming solution with mechanical stirring;

[0035] (2) Mix 1.2 mL of tannic acid ethanol solution (4.0 mg / mL) with 0.3 mL of silver nitrate aqueous solution (0.25 mg / mL), and react in a constant temperature water bath at 35°C for 12 hours to prepare a silver nanoparticle solution;

[0036] (3) The silver nanoparticle solution prepared in step (2) and 0.03 g of dopamine are added to the film-forming solution prepared in step (1) and mixed uniformly to prepare the high-performance medical liquid band-aid.

Embodiment 3

[0038] A method for preparing high-performance medical liquid band-aids includes the following specific steps:

[0039] (1) Add 0.8g cellulose acetate, 0.2g castor oil, 0.4g triacetin, 3.0g benzyl alcohol to 10.0g ethyl acetate solution, and fully dissolve it into a film-forming solution with mechanical stirring;

[0040] (2) Mix 2.0 mL of tannic acid ethanol solution (1.5 mg / mL) with 0.2 mL of silver nitrate aqueous solution (0.3 mg / mL), and react in a constant temperature water bath at 40°C for 24 hours to prepare a silver nanoparticle solution;

[0041] (3) The silver nanoparticle solution prepared in step (2) and 0.01 g of dopamine are added to the film-forming solution prepared in step (1) and mixed uniformly to prepare the high-performance medical liquid band-aid.

Abstract

The invention discloses a high-performance medical liquid adhesive bandage. The liquid adhesive bandage contains the following raw materials (by weight): 80-120 parts of cellulose acetate, 20-50 parts of castor oil, 30-70 parts of glyceryl triacetate, 200-500 parts of benzyl alcohol, 80-1200 parts of ethyl acetate, 1-10 parts of dopamine, 40-400 parts of a silver nitrate aqueous solution and 100-500 parts of an ethanol solution. The adhesive bandage of the invention has a good antibacterial property and also has properties such as high adhesion to skin, waterproofness, air permeability, concealing performance and the like.

Description

Technical field [0001] The invention relates to the technical field of medical materials, in particular to a high-performance liquid band-aid with antibacterial, high adhesion and concealing functions. Background technique [0002] People will inevitably cause various skin injuries in daily life and work, and the methods for treating wounds on the market mainly include powder drugs, ointment drugs, band-aids, medical gauze, etc., but the drugs are waterproof and breathable. Poor, the biocompatibility is not ideal, but medical band-aids and gauze have no antibacterial properties and are prone to secondary infections. At present, many new medical dressings appear on the market. For example, the patent number CN 102772801 A discloses a wound spray for treating abrasions, and the patent number CN 105288722 A provides a kind of nitrocellulose. The waterproof and breathable liquid band-aids of membrane materials, but they only play the simplest protective effect on the wound surface, ...
