External use plaster for treating acute jerk contused wound

Abstract

The invention relates to an external paste for treating acute contusion, which is formed by mount layer, hydrophilic gel layer, and protective film. Wherein, the mount layer from outer to inner comprises sealing layer, separating laer, and pressure-sensitive paste layer; the sealing layer has one separator detachable, to separate the sealing layer into two independent chambers filled with chemical coolant. Compared with present technique, it uses hydrophilic gel layer to cool the skin, and controls the amount of coolants ammonium nitrate, sal soda and water, to control the refrigeration temperature and time, especially being used to save player on playground.

Description

technical field [0001] The invention belongs to the technical field of plaster for external use, in particular to the technical field of plaster for external use for treating acute sprains. Background technique [0002] People are prone to acute sprains in their daily work, especially when exercising. The pathological manifestations of acute sprains are tissue fiber rupture, local hemorrhage, inflammatory substance exudation and infiltration edema; the clinical manifestations are rapid pain, Symptoms such as swelling and dysfunction. Doctors use cryotherapy in the early stage of acute sprains. The cryotherapy is a method of treating diseases locally on the human body with a low-temperature medium lower than that of the human body. It does not cause destruction and death of tissue cells. Early changes, proper freezing can shrink blood vessels, inhibit exudation, paralyze nerves, and prevent pain. The most suitable freezing temperature is 22-25°C (the temperature here is the ...

Problems solved by technology

Commonly used cryotherapy is to freeze water into ice cubes, put the ice cubes in bagged containers to make ice packs, put the ice packs on the injured part of the patient, and use ice packs for cold compress. If the freezing temperature is too low, non-freezing frostbite reactions are prone to occur; in order to avoid non-freezing frostbite caused by low local temperature, some people use ice packs locally for a short time, but the sudden freezing and heating will cause stress reactions in the human body and cause injuries. The microvessels in the site are significantly expanded, which increases the permeability of the blood vessels, increases the exudation, aggravates the swelling of the patient, and prolongs the recovery period, which is not conducive to the treatment of acute sprains.
