Description

Technical Field

[0001] This utility model relates to the field of hot and cold compress bags, specifically hot and cold compress bags. Background Technology

[0002] Cold and hot compresses relieve pain, reduce swelling, promote blood circulation, and accelerate wound healing through different temperature stimuli. When applying a cold compress, the low temperature stimulates vasoconstriction and inhibits nerve conduction, effectively relieving bleeding from external injuries or exudation of tissue fluid, reducing pain sensitivity, and is suitable for symptoms such as acute injuries, headaches, toothaches, and heatstroke. When applying a hot compress, the heat helps dilate blood vessels, relax muscles and joints, promote blood circulation, relieve muscle spasms, and accelerate the recovery from inflammation. Cold and hot compresses are usually achieved by placing a phase change layer in a storage bag. The phase change layer is formed by thermoplastic sealing of phase change energy storage material in a sealed bag. When using it, the phase change layer is taken out according to the choice of hot or cold compress. The phase change layer is pre-cooled or preheated, and then placed in the storage bag for cold or hot compress.

[0003] Currently, when the phase change layer is placed in a storage bag after pretreatment, the storage bag itself has a fixed thickness, and different users have different skin temperatures and acceptable temperatures. This means that users who are more sensitive to temperature need to add a layer of cloth to the outside of the hot and cold compress bag for isolation, which is quite troublesome.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] The technical solution adopted by this application to solve its technical problem is: a hot and cold compress bag, including a first outer bag, a second outer bag is attached to one side of the first outer bag, and a protective component is attached to the outer wall of the second outer bag. The protective component is used to increase the thickness of the second outer bag.

[0007] Furthermore, the inner wall of the first outer bag is provided with a first placement groove, the inner wall of the first outer bag is attached with Velcro around its perimeter, and the inner wall of the first placement groove is embedded with an insulation layer.

[0008] Furthermore, a second mounting groove is provided on one side of the inner wall of the second outer bag, and a female Velcro fastener is attached to the four sides of the inner wall of the second outer bag.

[0009] Furthermore, horizontal straps are fixedly installed on both sides of the opening of the second placement groove, a phase change layer is installed in the inner cavity of the second placement groove, and a first Velcro is embedded around the outer wall of the second placement groove.

[0010] Furthermore, the insulation layer is made of thickened aluminum foil or tin foil.

[0011] Furthermore, the protective component includes a wrapping soft rubber layer and a second Velcro strap embedded around the inner wall of the wrapping soft rubber layer.

[0012] The beneficial effects of this application are as follows: The hot and cold compress bag provided by this application first removes the phase change layer according to the choice of hot or cold compress. After pre-cooling or preheating the phase change layer, it is inserted into the inner cavity of the second placement slot during use. By attaching the male Velcro straps around the inner wall of the first outer bag and the female Velcro straps around the inner wall of the second outer bag, the phase change layer can be accommodated through the first and second outer bags. At the same time, during use, the side of the insulation layer installed on the inner wall of the first placement slot is away from the area to be treated with cold or hot compress. If the user feels that the temperature of the hot and cold compress bag is uncomfortable, a soft rubber layer can be installed on the outer wall of the second outer bag by attaching it with the first and second Velcro straps. The soft rubber layer allows the user to contact the area to be treated with cold or hot compress as needed, and can isolate a certain temperature for use, making it convenient to use.
