Description

Flexible cold and hot compress belt

Technical Field

The invention relates to a flexible cold and hot compress belt, which aims to design a cold and hot compress belt for cold compress or hot compress in a flexible and fitting manner by matching with a human body curve.

Background

The traditional cold and hot compress device takes cold water or hot water and other liquids as cold and hot conducting media, and the liquids circulate in a preset pipeline to achieve the purpose of cold compress or hot compress, so that the size is larger, the temperature energy of the cold water or the hot water is reduced along with the increase of the distance of the circulating pipeline, the temperature difference between a cold and hot generation source and the tail end of the circulating pipeline is caused, a long time delay is also generated when cold and hot are switched, and the use is not convenient.

Under the continuous progress of science and technology, because of the small volume and fast heating speed of the electrothermal refrigeration chip, the electrothermal refrigeration chip is mostly used as a temperature generating source in the present cold and hot compress device, so as to overcome the defects of the traditional cold and hot transfer medium using cold water or hot water, for example: in the prior art, taiwan patent publication No. M456188 discloses a cold and hot compress pad, which adopts a cross-shaped metal sheet as a cold and hot conduction interface, and an electrothermal refrigeration chip disposed in the center of the cross-shaped metal sheet, so that when in use, the cross-shaped metal sheet is bound on a human body, and temperature energy can be conducted through the metal sheet, thereby rapidly providing cold compress or hot compress function.

However, in the structure of M456188, the metal sheet is concentrated and fast in speed for transferring temperature energy, so that the metal sheet is easily located at the assembly position of the electrothermal refrigeration chip, the temperature overheating or supercooling problem is generated at the part for linearly transferring temperature in a short distance, and the temperature difference is generated between the metal sheet and the part of the tail end far away from the electrothermal refrigeration chip, so that a user can feel uneven temperature.

Furthermore, the M456188 uses an elastic bandage to position the band body and the metal sheet on the human body, which not only easily causes the trouble of displacement of the elastic bandage during the operation process, but also causes the metal sheet to be difficult to effectively attach to the skin due to the material characteristics, and needs to be repeatedly adjusted to a proper position, thus causing the unsatisfactory use convenience and comfort. In addition, the electrothermal refrigeration chip of M456188 is permanently fixed, and cannot be assembled on another metal sheet for use in a dismounting manner from the belt body, so that the application range is limited.

In addition, in order to control the temperature of the hot and cold compress device at a suitable temperature, some commercial products appeal to intelligent control, and limit the temperature range to prevent scald or frostbite, but different users have different tolerable temperatures and time, so the use time and temperature adjustment setting of the hot and cold compress device still have needs.

In view of the above-mentioned deficiencies of the prior art, the present inventors have accumulated many years of research and practical experience in the related fields, and have devised a flexible cold and hot compress belt, which has improved the problems of the conventional cold and hot compress pad that the metal sheet is used as the cold and hot conduction interface and cannot be tightly attached to the human body, and the electrothermal refrigeration chip cannot be disassembled and assembled, and the temperature conduction is too concentrated, resulting in the disadvantages of scald or frostbite of the human body.
