[0003] Traditional wound dressings have the following shortcomings: can cause skin allergic reactions in a small number of people; adhere to the wound, causing mechanical re-injury when replaced; limited absorption capacity; not waterproof or waterproof and airtight; bacteria can easily penetrate and infect, and scab It hinders the healing of the wound; the smeared part is white due to the adhesive tape; the size of the area covered and the movable part are limited; frequent replacement, easy to leave debris; the wound surface is severely dehydrated, and the wound healing time is long; it cannot be degraded, although the volume is not large still trash
CN105363066A discloses a film that uses PVB and PVP as film-forming components, which ensures better film tensile strength and shorter film-forming time, but polyethylene polymers have poor air permeability, are difficult to decompose, and are easy to pollute the environment

Embodiment 1
[0029] The liquid band-aid of this embodiment consists of the following components: 6g of polyacrylic acid resin, 10g of butyl benzyl phthalate, 15g of propylene glycol, 20g of ethanol, 0.5g of menthol, and 48.5g of purified water.
[0030] The preparation method of the liquid band-aid of the present embodiment is as follows:
[0031] (1) In the mixing tank, first add the formula amount of 30%-45% butyl benzyl phthalate, raise the temperature to 45°C-65°C, add polyacrylic acid resin evenly while stirring, keep warm and swell for 16-24 hours , to get A mixture;
[0032] (2) Add the formulated amount of propylene glycol to the above-mentioned A mixture, raise the temperature to 45°C-65°C, heat and stir for 1-2 hours, cool down to 35°C-40°C, add the formulated amount of ethanol and the remaining amount of butyl benzyl phthalate base ester, adjust its pH value between 5-5.5 (a small amount of acetic acid can be added), keep stirring for 6-8 hours to obtain the B mixture;

Abstract
The invention belongs to the technical field of medical instruments and particularly discloses a liquid band-aid. The liquid band-aid is prepared from a film forming ingredient, a plasticizer and a solvent, wherein polyacrylic resin serves as the film forming ingredient. With polyacrylic resin serving as the main ingredient, the liquid band-aid can be volatized immediately when smeared to a wound and form a semi-transparent adhesive film which is very soft, good in air permeability, rich in elasticity and very thin, the effects of wound contamination prevention and protection can be performed, and the water-proof feature is achieved; the liquid band-aid is convenient to use and capable of providing the best moist environment needed by wound healing to the maximum and being applied to sensitive skin. The liquid band-aid has the functions of wound infection prevention, protection and water proofing, can be used for bruising, protection of a sutured part generated after a surgical operation, skin allergies, barb scratching, cracks, rhagades, tiny knife cut, mosquito bite prevention, quick blood crust, scar and mosquito mark removal and the like.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and specifically discloses a liquid band-aid and a preparation method thereof. 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] Traditional wound dressings have the following shortcomings: can cause skin allergic reactions in a small number of people; adhere to the wound, causing mechanical re-injury when replaced; limited absorption capacity; not waterproof or waterproof and airtight; bacteria can easily penetrate and infect, and scab ...
