Self-heating patch

Abstract

The invention discloses a self-heating patch. The self-heating patch is characterized by comprising a bag-like support, a self-heater, and an adhesive layer. The self-heater is disposed in the bag-like support. The adhesive layer is laminated on the bag-like support. A paraffin layer is further laminated on the adhesive layer and mainly comprises mixture of paraffin and beewax. The outer side of the paraffin layer contacts with human skin. Compared with the prior art, the self-heating patch is provided with the additional paraffin layer. By physical therapeutic action of wax therapy and blocking action of the paraffin layer, heat generated by the self-heater is conducted to the paraffin layer first, and the paraffin layer receives heat to heat up. The paraffin layer is high in heat capacity and low in heat conductivity, so that low-temperature burn by the self-heating patch can be avoided effectively. Through heating is even, deep and lasting, disorderliness and superficialness of the self-heating patch are changed, the self-heating patch is safe and comfortable, and curative effect is improved greatly.

Description

technical field [0001] The invention relates to a self-heating patch. Background technique [0002] The passive heat-producing patch is made with oxidative heating technology to treat cold-damp arthralgia, which is called ironing, and is an important part of the external treatment of traditional Chinese medicine. Timeless. Because thermal energy can also promote the absorption of transdermal administration, various self-heating patches emerge in an endless stream in the medical market. But all self-heating plasters all exist the difficult problem that has not been solved so far, 1, low-temperature scald, the tissue damage that takes place because of warm at sticking site, often causes doctor-patient dispute. 2. High heating peak, low maintenance temperature, disordered heat production, and poor comfort. [0003] Application of self-heating technology for local sticking therapy has a long history in my country and is accepted by patients. But low temperature scald cannot ...

AI Technical Summary

Problems solved by technology

However, all self-heating patches have problems that have not been solved so far. 1. Low-temperature burns, tissue damage at the application site due to heat, often leading to doctor-patient disputes

2. High heating peak, low maintenance temperature, disordered heat production, and poor comfort

The temperature control technology adopted abroad also does not solve this problem very well, and it is expensive
