Cold compression patch for traumatic injury and preparation method of cold compression patch

Abstract

The invention discloses a cold compression patch for traumatic injury. The cold compression patch comprises a back lining layer, a gel medicine layer and an anti-sticking layer, wherein the gel medicine layer comprises the following raw materials: sodium polyacrylate, Carbomer, glycerin, aluminium glycinate, tartaric acid, purified water, medical borneol, camphor, diclofenac sodium, menthol, belladonna liquid extract, cinnamon oil, propylene glycol, medical azone, diphenhydramine and peppermint oil. The invention further discloses a preparation method of the cold compression patch for traumatic injury. A gel medicine is prepared firstly and then applied to the back lining layer by a machine, the gel medicine layer is formed and covered with the anti-sticking layer, and the cold compression patch for traumatic injury is obtained after slitting, punching and slicing. The cold compression patch contains no additive, is directly applied without heating, adopts a simple process, has no chemical residue, is non-allergic and non-irritant, is high in drug loading capacity and moisture retention, well compatible with skin, resistant to aging and weather, lasting in adhesion and lower in production cost, can be torn and pasted repeatedly and facilitates popularization.

Description

technical field [0001] The invention relates to a biological patch and a preparation method thereof, in particular to a Dieda cold compress and a preparation method thereof. Background technique [0002] Traumatic injuries include knife and gun, falls, beatings, sudden contusions, stab wounds, abrasions, sports injuries, sprains, etc. The wounds often have pain, swelling, bleeding or fractures, dislocations, etc. The most suitable for treatment with biological plasters is the early stage There was no open wound in local soft tissue injury.

AI Technical Summary

Problems solved by technology

[0004] Most of the traditional bruise plasters only have analgesic effect and do not have cold compress effect, but simple pain relief without cold compress will intensify the expansion of blood vessels in the affected area, and the bleeding and edema will also increase accordingly, which will not only cause soft tissue adhesion and weaken local function, but also extremely It is easy to enhance the pain; the traditional production method of traumatic injury stickers is as follows: melt the hot melt adhesive as a base, add organic solvents and mix with various raw materials to make a coating and heat it for coating. There are chemical solvent residues, and the production process is cumbersome. And there is a flammable safety hazard. The product is irritating to the skin when it is used, and it cannot be pasted again after being peeled off; more specifically, there are the following defects:

[0006] 2. The stickiness of the hot sol of traditional bruise stickers is difficult to last, which leads to the short-lasting sticking time of the patch, and it can only be pasted once, and cannot be repeatedly peeled off;

[0007] 3. The preparation process of traditional bruise stickers is complicated, and there are hidden dangers of inflammability and explosion;

[0008] 4. The traditional bruise plaster is dissolved by adding a large amount of organic solvent, which is irritating to the skin
