Problems solved by technology

The traditional cold compress has the following problems: 1. There is no barrier to prevent bacteria from invading;
[0003] 2. The gel fits poorly and is inconvenient to wear; 3. The gel directly adheres to the skin, causing damage to the skin, and it cannot be used on the wound site; 4. The heat is taken away by evaporating water, and the temperature cannot be accurately controlled
[0006] Again, due to the poor stability of natural polymer materials, it is easy to degrade

Embodiment 1

[0025] (1) Preparation of solution A: 0.3% by weight of menthol, 0.5% of vitamin E, 19% of glycerin, and 0.4% of apple extract were added to ethanol with a weight percentage of 4% as a solvent;

[0026] (2) Prepare solution B: add 0.8% hemicellulose and 0.2% konjac gum powder to 74.7% by weight purified water, and dissolve at 50°C until completely dissolved;

[0027] (3) Prepare solution C: accurately weigh 100g of potato starch and 3g of sodium trimetaphosphate in a test tube, add 400ml of purified water, and slowly add a 10% NaOH solution dropwise while stirring at 40 degrees Celsius. Keep the reaction pH value at 11, and keep it warm for 3 hours to obtain a cross-linked potato starch solution;

[0028] (4) Stir the 0.1% by weight solution C with the above solutions A and B at 40°C to form a gel.

Embodiment 2

[0030] (1) Preparation of solution A: 0.3% by weight of menthol, 0.5% of vitamin E, 19% of glycerin, and 0.4% of apple extract were added to ethanol with a weight percentage of 4% as a solvent;

[0031] (2) Preparation of solution B: Add 0.8% hemicellulose and 0.2% konjac gum powder to 74.3% by weight purified water, until completely dissolved at 50°C;

[0032] (3) Prepare solution C: accurately weigh 100g of potato starch and 3g of sodium trimetaphosphate in a test tube, add 400ml of purified water, and slowly add a 10% NaOH solution dropwise while stirring at 40 degrees Celsius. Keep the reaction pH value at 11, and keep it warm for 3 hours to obtain a cross-linked potato starch solution;

[0033] (4) Stir the 0.5% by weight solution C with the above solutions A and B at 40°C to form a gel.

Embodiment 3

[0035] (1) Preparation of solution A: 0.3% by weight of menthol, 0.5% of vitamin E, 19% of glycerin, and 0.4% of apple extract were added to ethanol with a weight percentage of 4% as a solvent;

[0036] (2) Preparation of solution B: Add 0.8% hemicellulose and 0.2% konjac gum powder to 72.8% by weight purified water, until completely dissolved at 50°C;

[0037] (3) Prepare solution C: accurately weigh 100g of potato starch and 3g of sodium trimetaphosphate in a test tube, add 400ml of purified water, and slowly add a 10% NaOH solution dropwise while stirring at 40 degrees Celsius. Keep the reaction pH value at 11, and keep it warm for 3 hours to obtain a cross-linked potato starch solution;

[0038] (4) Stir the 2% by weight solution C with the above solutions A and B at 40°C to form a gel.

Abstract

The invention discloses a cold application patch containing a cold storage gel and a preparation method thereof. The cold storage gel comprises the following components: menthol, ethanol, glycerol, vitamin E, apple extract, konjak gelatine powder, hemicellulose, glycerol and cross-linked potato starch.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a cold storage gel, a preparation method thereof and a cold compress. Background technique [0002] Cold compress patch is a kind of cold compress product with cold storage gel as the core, which is improved according to the traditional cold compress method. The principle of the traditional cold compress is that the gel is attached to the skin, the temperature of the skin on the body surface is transmitted to the cold gel, the heat is absorbed by the water molecules in the gel, and a large amount of heat is taken away by the evaporation of water, which can quickly reduce the local temperature of the skin on the body surface. Temperature, reduce the burning sensation, pain and sensitivity of the local skin, so as to achieve the effect of physical cooling and cold compress physiotherapy. The traditional cold compress has the following problems: 1. There is no barrier to p...
