Constant-temperature cold compress bag

Abstract

The invention relates to a constant-temperature cold compress bag applicable to fever cooling and rehabilitation therapy. According to the principle that organic phase change materials produce constant temperature phase changes at low temperature and absorb a large amount of latent heat, the cold compress temperature is effectively controlled, and the cold compress effect is improved; meanwhile, the organic phase change materials have the certain plasticity before complete intersection, and therefore the fit performance of the cold compress bag can be improved. The cold compress bag can be manufactured in different shapes, the fit effect is improved, and therefore the cold compress requirements of different portions are met.

Description

technical field [0001] The invention relates to a constant temperature cold compress bag, in particular to a constant temperature cold compress bag used for fever cooling and cold compress physiotherapy rehabilitation. Background technique [0002] Cold compress is a treatment method that uses low temperature to stimulate the human body to achieve cooling, pain relief, hemostasis, reduce inflammatory edema and exudation, and promote wound healing. The common cold compress is to put the refrigerant into the bag to make a cold compress bag, and apply it to the injured part to achieve the effect of cooling cold compress, and make the cold compress bag into different shapes to better fit different parts of the human body and enhance the cold compress Effect. If there is a cold compress bag specially used for facial cold compress (patent application number 201020611734.0, named as a kind of facial cold compress bag), nasal cold compress bag (patent number 200920078136.9, named a...

AI Technical Summary

Problems solved by technology

The refrigerant in the cold compress bag mostly uses low-temperature water, and the water becomes hard after freezing at 0°C, which makes it less comfortable to contact with the human body, and the bonding effect is not good, which affects the effect of cold compress. Small pieces of crushed ice can partially solve the problems of hardness, poor comfort, and poor fit. However, after the ice slowly melts, leakage often occurs, and the injured part will be infected, which will affect the recovery of the human body; the use of waterproof The bag can solve the problem of water leakage, but the temperature of the ice in the cold pack is generally 0°C or even lower, which is likely to frostbite the human body and cause secondary damage

The invention patent with the application number 201210126552.8 and the name "a cold storage type refrigerant and cold storage type cold compress bag" discloses a new type of cold storage agent, which consists of 30-40% urea, 6-12% ammonium chloride, nitric acid Potassium 6-12%, melon 2-5%, water 35-45%, the refrigerant temperature can be as low as 2 ℃, but these raw materials are common agricultural fertilizers, when used as a cold compress bag, once the solution leaks or the bag body If it is damaged and the cooling agent flows out, it will pollute the environment and human wounds, and cause secondary damage to the human body

[0003] As mentioned above, currently commonly used cold compress bags have problems such as hard cold compress materials, poor fit, low temperature, easy to cause frostbite, wound infection caused by water leakage, and unsafe refrigerant. The temperature of the cold compress changes greatly, and the effect of the cold compress is not good, etc.
