Cold and hot compress bag

Abstract

The present invention relates to a cold and hot compress bag. The cold and hot compress bag comprises a compress bag body, straps, and a semiconductor refrigeration / heating sheet, a heat dissipating component and a medium temperature guiding chamber arranged in the compress bag body, the heat dissipating component comprises a water tank and a water pump; the medium temperature guiding chamber is arranged on the compress bag body and in contact with the semiconductor refrigeration / heating sheet, and the semiconductor refrigeration / heating sheet transmits temperature after refrigeration or heating to a temperature guiding medium of the medium temperature guiding chamber; and the compress bag body is further internally provided with power supply, the power supply is connected with the semiconductor refrigeration / heating sheet and the water pump through a three-gear six-foot ship-type switch, the three-gear six-foot ship-type switch is used to switch a current direction, and the refrigeration or heating of the semiconductor refrigeration / heating sheet is realized. The cold and hot compress bag is simple in structure, convenient to use and low in manufacturing cost, the refrigeration / heating sheet can realize the long-time refrigeration or heating, and at the same time, cold compress and hot compress functions can be realized; and in addition, the heat dissipating component solves aheat dissipation problem of the refrigeration sheet and avoids a problem that heat generation of the refrigeration sheet leads to short service life.

Description

technical field [0001] The invention relates to the technical field of disease care, in particular to a hot and cold compress bag. Background technique [0002] Physiotherapy is playing an increasingly important role in modern medical teams. It achieves therapeutic effects through the characteristics of physical factors such as sound, light, water, electricity, cold, and heat. Among various physical therapy methods, cold compress and hot compress are the most commonly used means. [0003] When applying cold compresses, in addition to lowering body temperature, it will also constrict blood vessels and reduce metabolic rate, so as to relieve pain and inflammation. Hot compresses will increase body temperature, cause blood vessels to relax, increase the body's metabolic rate, so as to increase the elasticity of ligaments, joint capsules, and muscles, and promote healing.

AI Technical Summary

Problems solved by technology

[0004] Existing hot and cold packs such as the Decathlon aptonia sports ice pack is a hot and cold pack that can be used repeatedly, but it needs to be frozen in the refrigerator or heated with hot water for a long time (more than two hours) before it can be used. The time cost required is very high

[0005] However, some existing disposable quick-cooling ice packs can be used quickly, but they can only be used once, which will cause waste, and users will find it very troublesome to buy this ice pack many times.

Disposable quick-cooling ice packs are generally refrigerated with materials such as ammonium nitrate or sodium sulfate decahydrate. If these materials leak, they will easily cause environmental pollution.

[0006] However, users must quickly apply ice compresses after fractures or sprains, usually in about 20-60 minutes, and the existing hot and cold packs

[0007] Usually it does not have a fixed function, and the patient must fix the cold and hot compress bag on the affected part in a hand-held manner, which is quite inconvenient, so the above-mentioned cold and hot compress bag is difficult to meet the requirements
