Problems solved by technology

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

[0016] A liquid band-aid, comprising the following components by weight: 7 parts of acrylic copolymer, 11 parts of polyvinyl alcohol and polyethylene glycol copolymer, 5 parts of polysorbate 80, 3 parts of glycerol, bicarbonate 3 parts of sodium, 3 parts of sodium hydroxide and 60 parts of purified water.

[0017] A liquid band-aid, comprising the following components by weight: 15 parts of acrylic copolymer, 20 parts of polyvinyl alcohol and polyethylene glycol copolymer, 10 parts of polysorbate 80, 5 parts of glycerol, bicarbonate 5 parts of sodium, 5 parts of sodium hydroxide and 96.8 parts of purified water.

[0018] A liquid band-aid, comprising the following componen...

Embodiment 2

[0020] A preparation method of the liquid band-aid described in Example 1 comprises the steps of: stirring sodium bicarbonate and sodium hydroxide until fully dissolved, then adding acrylic acid copolymer, polyvinyl alcohol and polyethylene glycol copolymer, and dispersing evenly Finally, add polysorbate 80 and glycerol, and stir until completely dissolved.

[0021] The specific preparation method is as follows:

[0022] 1. Weigh the amount of sodium bicarbonate and sodium hydroxide, and stir until completely dissolved.

[0023] 2. Dissolve the polysorbate 80 and glycerin of the ingredients in the aqueous solution in "step 1", then add the acrylic copolymer, polyvinyl alcohol and polyethylene glycol copolymer of the ingredients to dissolve, and stir until Dissolve completely or use auxiliary dissolution methods such as heating and ultrasound to promote dissolution.

[0024] Step 2 can also be: the sequence of adding samples is exchanged: add the acrylic acid copolymer of bat...

Embodiment 3

[0027] Clinical application test of liquid band-aid of the present invention:

[0028] 1. A total of 64 patients with mild trauma were collected in this study, including 32 cases in the treatment group and 32 cases in the control group. There were 36 males and 28 females, aged 16 to 65 years, with an average (32.48±4.58) years old. There was no significant difference in gender, age and medical history between the two groups of patients, and they were comparable. Therefore, this clinical trial adopts a randomized parallel controlled trial design. The subjects were randomly divided into experimental and control groups.

[0029] 2. Inclusion criteria:

[0030] 1) Age 16-65, male or female.

[0031] 2) Volunteer to participate in this clinical trial and sign an informed consent form.

[0032] 3) Skin damage (mechanical damage), mild burns (with a history of flame burns or high-temperature liquid burns; the skin of the wound is red, swollen, painful, hot, no blisters, allergie...

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular to 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] 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...
