Embodiment 1

[0029] Take 1.5kg of styrene-isoprene block copolymer and 1.2kg of medical grade white oil to melt in the reactor, the temperature is controlled at 140~170℃; until the styrene-isoprene block copolymer is completely melted Finally, add 1.8kg rosin to the reaction kettle and keep it warm for a period of time; take 2.0kg gelatin, 3.1 kg carboxymethyl cellulose sodium and 0.4kg carboxymethyl chitosan and mix them evenly, then slowly add them into the reaction kettle and keep stirring , after completely mixing uniformly, cooling and defoaming; then the obtained mixture is evenly coated on a thin polymer film, that is, the hydrocolloid layer is coated on the backing layer, and the thickness of the hydrocolloid layer is 2.5mm, and the temperature is lowered; finally Cover the hydrocolloid layer with glassine paper, and cut it into specifications with a width of 5.08 cm and a length of 8 cm.

[0030] The self-adhesive elastic bandage has a width of 2 inches (5.08cm) and a length of 3 ...

Embodiment 2

[0032] Dissolve 6g of polyvinyl alcohol in 150g of distilled water. After completely dissolving, add 2g of chitosan hydrochloride, 40g of sodium polyacrylate, and 2g of gelatin, stir to dissolve completely, vacuumize and defoam, and then pour the mixed solution on an On the textile, it is irradiated with a high-energy electron accelerator, and the irradiation dose is 60kGy. The thickness of the hydrogel layer was 2.0 mm. Then cut it into specifications with a width of 10.16cm and a length of 12cm.

[0033] The self-adhesive elastic bandage has a width of 4 inches (10.16cm) and a length of 4 meters. As a backing, the above-mentioned hydrogel dressing is fixed at 5 cm from the end of the self-adhesive elastic bandage through an adhesive.

Embodiment 3

[0035] Take the pure cotton fiber and polyethylene mesh composite dressing, and cut it into specifications with a width of 7.62 cm and a length of 8 cm.

[0036] The self-adhesive elastic bandage has a width of 3 inches (7.62cm) and a length of 2 meters. As a backing, the above-mentioned pure cotton fiber and polyethylene grid composite dressing is fixed by an adhesive at the 5cm position of the end of the self-adhesive elastic bandage.

[0037] In summary, the self-adhesive elastic bandage of the present invention can be directly attached to the patient's wound, is convenient to use, can absorb wound exudate, and has bactericidal and anti-inflammatory effects. It has changed the deficiency that the traditional self-adhesive elastic bandage cannot directly contact the wound, and can make the patient more comfortable and convenient when bandaging the injured part, and is more suitable for use in emergency situations.

Abstract

The invention relates to a self-adhesive elastic bandage capable of being directly used on a wound. Self adhesives are coated on the front surface and the back surface of a back lining. A wound contact pad is fixed at a position which is 5-8cm far away from the end of the back lining through adhesives. The length of the wound contact pad is 3-15cm and the width of the wound contact pad is equal to the width of the back lining. The wound contact pad is made of hydrogel, hydrocolloid or a fiber and polyethylene latticed composite material. Since the wound contact pad is fixed on the back lining through the adhesives, a buffer effect on the wound is taken and the wound is prevented from being polluted by pollutants. The self-adhesive elastic bandage can be directly attached onto the wound of a patient, is convenient to use, can absorb wound effluents and has a sterilization and anti-inflammation effect.

Description

technical field [0001] The invention relates to a self-adhesive elastic bandage directly used for wounds, belonging to the technical field of medical elastic bandages. Background technique [0002] Self-adhesive elastic bandages have been widely used in medical treatment, sporting goods and other fields, but there is one biggest disadvantage when using them. They cannot be used directly on wounds. When using them, anti-inflammatory drugs should be put on the wounds, disinfected gauze, and then self-adhesive bandages should be used. Fixing is inconvenient and time-consuming. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a self-adhesive elastic bandage directly used on wounds and a manufacturing method thereof, which can be directly used on wounds for dressing and fixing. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The se...
