Problems solved by technology

In order to shorten the film-forming time, liquid band-aids made by adding a large amount of alcohol-based organic solvents will have a strong tingling sensation during use, which makes patients fearful and prefers to use traditional band-aids; water-soluble polymers are used as film-forming Although the material has excellent water absorption and swelling properties during preparation, it is not possible to add a large amount of volatile organic solvents (incompatibility) to shorten the film-forming time (some products even reach more than 10 minutes), because it cannot meet the needs of patients for rapid film-forming and convenience. Therefore, it will greatly affect the patient's willingness to accept the product

Embodiment 1

[0042] Weigh 30 parts by mass of ethanol, 10 parts by mass of isoamyl acetate, and 30 parts by mass of ethyl acetate, and mix them uniformly to obtain a solvent. Weigh 10 parts by mass of nitrocellulose and add it to the above solvent, and stir in an airtight manner until the nitrocellulose is dissolved uniformly. transparent

[0043] Add 9 parts by mass of isopropyl palmitate and 9 parts by mass of triethyl citrate to the above solution and stir evenly; then add 0.08 parts by mass of bioactive glass, 0.5 parts by mass of tocopheryl acetate, and 0.5 parts by mass of borneol, and stir uniform.

[0044] Stand still, so that the air bubbles in the container disappear, and a liquid band-aid is obtained.

Embodiment 2

[0046] Weigh 25 parts by mass of ethanol, 25 parts by mass of isoamyl acetate, and 20 parts by mass of ethyl acetate, and mix them uniformly to obtain a solvent. Weigh 5 parts by mass of nitrocellulose and add it to the above solvent, and stir in an airtight manner until the nitrocellulose is dissolved evenly. transparent

[0047] Add 5 parts by mass of isopropyl palmitate and 15 parts by mass of triethyl citrate to the above solution and stir evenly; then add 1.5 parts by mass of bioactive glass, 1.5 parts by mass of tocopheryl acetate and stir, 2 parts by mass of borneol, Stir well.

[0048] Stand still, so that the air bubbles in the container disappear, and a liquid band-aid is obtained.

Embodiment 3

[0050] Weigh 15 parts by mass of ethanol, 25 parts by mass of isoamyl acetate, and 12 parts by mass of ethyl acetate, and mix them uniformly to obtain a solvent. Take 15 parts by mass of nitrocellulose and add it to the above solvent, and stir in an airtight manner until the nitrocellulose is dissolved evenly. transparent

[0051] Add 14 parts by mass of isopropyl palmitate and 12 parts by mass of triethyl citrate to the above solution and stir evenly; then add 3 parts by mass of bioactive glass, 0.8 parts by mass of tocopheryl acetate and stir, 3 parts by mass of borneol, Stir well.

Abstract

The invention provides a liquid band-aid and a preparation method thereof. The liquid band-aid consists of a film-forming agent, a solvent and bio-active glass. According to an embodiment, the liquidband-aid provided by the invention has functions of preventing wound infection, protecting wounds and water-proofing; and the liquid band-aid is applicable to protection of scratched and surgically sutured sites, skin allergy, scratched hangnails, cracks, chapped skin, small tool marks, scratched parts due to mosquito bites, rapid removal of blood crusts, scars and the like.

Description

technical field [0001] The invention relates to a band-aid, in particular to a liquid band-aid with functions of preventing wound infection and waterproofing. Background technique [0002] Trauma caused by trauma or surgery may adversely affect the wound during postoperative wound recovery due to activities such as bathing, outdoor activities, and wound contact. Therefore, it is particularly important to care for the wound. Transparent wound protective films, such as Band-Aids, play a vital role in wound protection. [0003] At present, traditional band-aids occupy most of the market share, and hospitals and pharmacies only sell traditional band-aids. The recognition of liquid band-aid is far less than that of band-aid, so the people who really understand the advantages of liquid band-aid and promote the application of liquid band-aid are often people with professional knowledge. Although traditional band-aids meet the clinical needs to a certain extent, their curative eff...
