Flexible electric heat therapy patch based on liquid metal

Abstract

The present invention provides a flexible electric heat therapy patch based on liquid metal. The flexible electric heat therapy patch based on the liquid metal comprises a flexible substrate (1), liquid metal (2), a packaging layer (3), a lead (4), a switch (5) and a power supply (6). A groove (11) is formed in the flexible substrate (1), the groove (11) is filled with the liquid metal (2), and the packaging layer (3) is arranged above the groove (11); the switch (5), the power supply (6), the lead (4) and the liquid metal (2) form a closed loop; and the groove is a combined pattern consistingof an H shape (111), a Chinese character "gan" (looks like a cross with a short line above) shape (112), a Chinese character "shi" (looks like a cross with a short line below) shape (113) and an X shape (114). The provided electric heat therapy patch can be repeatedly used, is softer and foldable, has better fit degree with human body, generates heat more uniformly, and is higher in cost performance and wider in application field.

Description

technical field [0001] The invention relates to the technical field of physiotherapy, in particular to a liquid metal-based flexible electrothermal therapy patch. Background technique [0002] At present, people's demand for continuous low-temperature heating continues to increase. For example, women will experience dysmenorrhea symptoms during their menstrual period, and need to use continuous low-temperature heating to relieve pain. They usually choose warm baby stickers. Warm baby paste heating material is mainly composed of iron powder, activated carbon, vermiculite, water, salt and other materials. The principle of heating is that the iron powder is naturally oxidized to release heat. Because it cannot react before use, the material of the bag must be very special, consisting of a raw material layer, a gelatin layer and a non-woven bag. The non-woven bag is made of a microporous breathable film, and it must have a conventional airtight outer bag. When in use, the ou...

Problems solved by technology

[0004] However, the current pads for low-temperature heating such as baby warmers have disadvantages such as non-reusable, not soft enough, and poor fitting effect. They cannot fit perfectly when in contact with hard parts such as knees, waist, and cervical spine, resulting in a large amount of heat loss. , not economical and widely applicable
