Background

Fever is now a very common symptom for infants and young children, and is a normal response of the human body to the initiation of the immune system against pathogens. However, the normal functions of human organs are damaged by high body temperature, especially high temperature of more than 38.5 ℃, which has great negative effects on the health of children, and even causes coma of children patients due to long-term high fever, and serious people have the risk of causing dementia. Because the infants can not accurately and effectively describe the state of illness, the diagnosis process is time-consuming and labor-consuming, and various examinations are required before the medication, the infants are in a high fever state for a long time and can not be rapidly cooled.

At present, some coolers on the market mainly have: (1) the basic structure of the cooling patch comprises an anti-sticking layer, a medicine storage gel layer, a back lining layer and the like, and the cooling principle is that excessive heat in the body is volatilized through vaporization of water in the gel, so that the purpose of reducing the body temperature is achieved.
