Abstract
Description
technical field
[0001] The invention relates to a cooling patch, in particular to a cooling patch for lowering the temperature of a human body, and belongs to the technical field of medical devices. Background technique
[0002] Fever in the human body is due to the action of heat activators on the body, resulting in the generation of endogenous pyrogens that are incorporated into the brain and act on the temperature regulation center, prompting the release of mediators in the heat center, thereby causing changes in the set point. Bacterial infectious fever and aseptic tissue injury fever can cause enhanced tissue metabolism, digestive dysfunction, muscle pain, headache, and even central nervous system dysfunction, sometimes unconsciousness and coma. The commonly used antipyretic methods are divided into physical cooling and taking antipyretic and analgesic drugs, but the side effects of drug cooling are large, and for infants and young children under 2 months, the World Hea...
Examples
Embodiment 1
[0033] Such as figure 1 As shown, a cooling patch, the effective cooling time of the cooling patch is not less than 2 hours, the cooling patch is in the form of a thin sheet as a whole, without the need for a backing material, and can be directly attached to human skin. The hydrogel main body 1 of the cooling patch is directly injection molded, including an upper surface 11 and a lower surface 12, and the material is compounded from natural gel substances potassium-sensitive carrageenan and konjac gum, with a water content of more than 90%. Furthermore, auxiliary cooling materials such as mint, wormwood, alcohol, and antipyretic drugs can be added inside the hydrogel main body 1, which not only gives the human skin a cool and comfortable feeling, but also enhances the cooling effect.
[0034] Such as figure 2 As shown, the existing cooling patch 2 is roughly composed of three parts, including a protective film 22 , a hydrogel main body 1 and a backing material 21 . The hydr...
