Existing conventional clothing and equipment only provide basic coverage, warmth, and wearability, lacking the function of TCM hot compress physiotherapy. The few garments on the market with physiotherapy functions mostly only have simple pockets for storing herbal medicine packets, relying solely on body heat to slowly release the medicinal properties, resulting in weak and slow-acting therapeutic effects. Some wearable physiotherapy hot compress devices have a hot compress function but lack the ability to hold medicinal herbs, lacking independent media storage structures and dedicated herbal medicine placement positions, failing to meet users' diverse needs for everyday wear, removable and washable components, and flexible warm compress physiotherapy. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a wearable device for physical therapy and heat application.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A wearable device for physiotherapy and hot compress includes: a device body; a medicine warming component, detachably installed on the device body, the medicine warming component including a medium container, the medium container having a medium receiving cavity, the medium receiving cavity having a medium inlet, the medium inlet being detachably fitted with a sealing element; the outer wall of the medium container having a medicine bag, the medicine bag being used to hold medicinal materials or medicine bags.

[0005] Furthermore, the medicine bag has an open opening at its upper end, and a sealing member is installed on the outer wall of the medium container. The sealing member has a sealed state and an open state. In the sealed state, the sealing member is used to press the upper end of the medicine bag to close the open opening. In the open state, the sealing member is detached from the upper end of the medicine bag to open the open opening.

[0022] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a wearable device for physiotherapy and hot compress, comprising a device body 100 and a warming medicine component 200.

[0023] The equipment itself (equipment 100) can be different forms of clothing, such as... Figure 1 The image shown is of a type of bellyband.

[0024] The warming device 200 is detachably installed on the equipment body 100. The warming device 200 includes a medium container 210, which has a medium receiving cavity and a medium inlet 211. A sealing element 212 is detachably installed on the medium inlet 211. A medicine bag 220 is provided on the outer wall of the medium container 210 for containing medicinal materials or medicine bags. Hot water can be added to the medium receiving cavity to achieve heat therapy. The medium container 210 can be made of transparent plastic.

[0025] This invention provides a wearable physiotherapy heat therapy device. A detachable warming medicine component 200 is mounted on the device body 100. The warming medicine component 200 forms an independent medium-containing cavity through a medium container 210 and is equipped with a medium inlet 211 with a sealing element 212. Heat therapy medium can be conveniently added into the medium-containing cavity. The sealing element 212 effectively seals the medium inlet 211 to prevent leakage and ensure safe use of the heat therapy. A medicine bag 220 is independently provided on the outer wall of the medium container 210, which can separately store medicinal materials or medicine bags, achieving separate placement of the heat therapy medium and physiotherapy medicines. The warmth generated by the medium within the medium container 210 accelerates the volatilization and penetration of the medicinal effects, significantly improving the efficiency of the physiotherapy and the health benefits compared to relying solely on the body's natural temperature for drug volatilization. Meanwhile, the warming medicine component 200 and the equipment body 100 adopt a detachable assembly structure, which can be removed from the equipment body 100 as needed for easy cleaning, maintenance and replacement; the medicine bag 220 can be put in and taken out at any time to replace different kinds of medicines or medicine bags, which can adapt to the health conditioning needs of different groups of people. It effectively makes up for the shortcomings of existing physiotherapy clothing that cannot simultaneously realize medium heat application and medicine therapy, lack independent medium holding structure and dedicated medicine placement position, and are inconvenient to disassemble and clean. It well meets the diversified use needs of users for daily wear, detachable cleaning and flexible warming medicine therapy.

[0026] In some embodiments of the present invention, such as Figure 6 As shown, the medicine bag 220 has an opening 221 at its upper end. The medicine bag 220 is made of fabric (such as cotton) and has ventilation holes. One side of the medicine bag 220 can be fixed to the periphery of the medium container 210 by heat sealing, glue, or rivets. A sealing element 230 is installed on the outer wall of the medium container 210, and the sealing element 230 has a sealed state and an open state; for example... Figure 3 As shown, the sealing element 230 in the sealed state is used to press the upper end of the medicine bag 220 to close the open opening 221; as Figure 5 As shown, the sealing element 230 in the open state detaches from the upper end of the medicine bag 220 to open the opening 221. The sealing element 230 is movably installed on the medium container 210 to achieve switching between the sealed and open states. By providing an opening 221 at the upper end of the medicine bag 220, it is convenient to put in medicinal materials or medicine packets. The switchable sealing element 230 is provided on the outer wall of the medium container 210. After the medicinal materials or medicine packets are put in, the sealing element 230 can be switched to the sealed state to press the upper end of the medicine bag 220 to close the opening 221, effectively preventing the medicinal materials or medicine packets inside the medicine bag 220 from slipping off and falling off during wear, thus affecting the user experience. When it is necessary to change the medicinal materials, simply switch the sealing element 230 to the open state to open the opening 221. The operation of taking out and putting in medicinal materials is convenient, taking into account both the reliability of use and the flexibility of operation.

[0027] In a further embodiment of the present invention, the upper end face of the medium container 210 is provided with a protruding bottle portion 213, a medium inlet 211 is formed in the bottle portion 213, and a sealing member 212 is threadedly connected to the bottle portion 213. The protruding bottle portion 213 can play a guiding role when adding the heat therapy medium, improving the convenience of the adding operation; the threaded connection between the sealing member 212 and the bottle portion 213 can improve the sealing reliability of the medium inlet 211, effectively preventing the leakage of the heat therapy medium in the medium receiving cavity. At the same time, the disassembly and assembly of the threaded connection is simple and convenient, and users can easily disassemble and assemble the sealing member 212 to replenish and replace the medium.

[0028] Reference Figure 6 In a further embodiment of the present invention, the sealing member 230 includes a sealing strip 231, with hinge strips 232 at both ends of the sealing strip 231. The sealing strip 231 is used to press against the upper end of the contact medicine bag 220. The hinge strips 232 on the left and right sides are respectively hinged to the left and right side walls of the medium container 210. The hinge strips 232 are respectively provided with corresponding holes in the side walls of the medium container 210 and are inserted into hinge shafts to achieve hinged connection. The hinge shafts can be installed by being threaded to the side walls of the medium container 210. Of course, in some other embodiments, a protruding cylinder can be provided on the hinge strip 232, and the cylinder is embedded in the groove of the side wall of the medium container 210 to achieve hinged installation. The sealing strip 231 has an extension strip 233, which extends upward from the sealing strip 231 in the sealed state. A horizontally extending pressure block 214 is provided on one side of the outer wall of the sealing element 212. When the sealing element 212 is screwed to abut against the upper surface of the medium container 210, the pressure block 214 fits against the upper end of the extension strip 233, keeping the sealing element 230 in a sealed state. The sealing element 212 can be screwed until the pressure block 214 is misaligned with the extension strip 233 to release the restriction on the upward movement of the extension strip 233. Through the linkage structure design of the sealing element 230 and the sealing element 212, the hinge strip 232 of the sealing element 230 is hinged to the medium container 210 for movable assembly. Simultaneously, an upwardly extending extension strip 233 is provided on the sealing strip 231, and a pressure block 214 is disposed on the outer wall of the sealing element 212. Figure 3 As shown, when the user screws the sealing element 212 until it abuts against the upper surface of the medium container 210 to seal the medium inlet 211, the pressure block 214 can simultaneously fit against the upper end of the extension strip 233, automatically locking the sealing element 230 in the sealed state. This eliminates the need for separate operation of the sealing element 230, allowing for simultaneous sealing of the medium inlet and the medicine bag, significantly simplifying the user's operation. Figure 4As shown, when it is necessary to open the medicine bag, simply twist the sealing element 212 to disengage the pressure block 214 from the extension strip 233, thus releasing the restriction on the sealing element 230. It is not necessary to completely unscrew the sealing element 212 to release the restriction on the sealing element 230. This highly interactive operation effectively improves the convenience of use and the reliability of the structure. Specifically, the pressure block 214 is located at the bottom of the sealing element 212, with its bottom surface flush with the bottom surface of the sealing element 212. The extension strip 233 extends upwards to contact the pressure block 214. During operation, the sealing component 230 will be pressed down to a near-sealed state due to gravity. First, tighten the sealing component 212 until it is about to interfere with the sealing component 230. At this time, one hand presses down on the sealing component 230 to keep it in a sealed state, while the other hand continues to tighten the sealing component 212 until the bottom of the sealing component 212 abuts against the upper surface of the medium container 210 and is tightened. At this time, the sealing component 230 can be released, and the pressure block 214 can contact the upper end of the extension strip 233 to limit the sealing component 230 and keep it in a sealed state.

[0029] In a further embodiment of the present invention, the upper end of the extension strip 233 is provided with a horizontally extending extension portion 234, and the upper end surface of the extension portion 234 in the sealed state is used to fit against the pressure block 214. By providing a horizontally extending extension portion 234 at the upper end of the extension strip 233, the contact area between the extension strip 233 and the pressure block 214 is increased, the reliability of the pressing and limiting is improved, and the pressure block 214 can stably press and lock the extension strip 233, further improving the working stability of the overall structure.

[0030] In a further embodiment of the present invention, a pressure block 214 is disposed at the bottom of the sealing member 212, and a first reinforcing rib 215 is provided between the pressure block 214 and the outer peripheral wall of the sealing member 212. By providing the first reinforcing rib 215 between the pressure block 214 and the outer peripheral wall of the sealing member 212, the connection strength between the pressure block 214 and the sealing member 212 can be effectively improved, avoiding problems such as deformation and breakage of the pressure block 214 during long-term pressing and stress, thereby enhancing the structural durability of the component and extending the service life of the overall component. In addition, the first reinforcing rib 215 also provides a stress-bearing position when screwing the sealing member 212, facilitating screwing.

[0031] In a further embodiment of the present invention, an arc-shaped closing strip 235 is provided on the side of the sealing strip 231 opposite to the extension strip 233. The arc-shaped structure effectively presses the sharp edges of the medicine bag 220, preventing damage to the medicine bag 220 and improving the lifespan of the device.

[0032] Reference Figure 2In a further embodiment of the present invention, the surface of the equipment body 100 is provided with a viewing port 110, and a shielding cloth 120 is movably connected to the outer surface of the equipment body 100 corresponding to the viewing port 110 so as to open or cover the viewing port 110. A storage pocket 130 is connected to the outer surface of the shielding cloth 120, and the medicine warming component 200 is installed in the storage pocket 130. By providing a viewing port 110 on the surface of the equipment body 100 and configuring an openable cover 120, while integrating a storage pocket 130 onto the outer surface of the cover 120 to install the warming medicine component 200, the user can directly observe the skin condition of the treatment area through the viewing port 110 without disassembling the warming medicine component 200. This allows the user to monitor the treatment process at any time, effectively avoiding problems such as skin burns caused by excessive heat application, thus improving the safety of the treatment. Simultaneously, the cover 120 can cover the viewing port 110 during treatment, providing auxiliary insulation and reducing heat loss. The storage pocket 130 provides stable positioning and fixation for the warming medicine component 200, preventing it from shifting during wear. It is understood that a zipper can be provided at the top of the storage pocket 130; when it is necessary to remove or replace the warming medicine component 200, the zipper can be pulled to open the storage pocket 130.

[0033] Reference Figure 2 In a further embodiment of the present invention, one edge of the inner surface of the shielding cloth 120 is connected to one edge of the viewing port 110, specifically by sewing together with a sewing thread, and the edges of the other three sides of the inner surface of the shielding cloth 120 are detachably connected to the edges of the other three sides of the viewing port 110. Specifically, the upper edge of the inner surface of the cover 120 is connected to the upper edge of the viewing port 110, and the left, right, and lower edges of the inner surface of the cover 120 are detachably connected to the left, right, and lower edges of the viewing port 110, respectively. This allows the cover 120 to be folded open and closed along a fixed side. When opening the cover 120, it is not necessary to completely remove it; simply folding it over is sufficient to expose the viewing port 110. This makes operation more convenient and avoids the problem of the cover being easily lost or misaligned after removal. At the same time, the detachable connection on the three sides can reliably fix the cover when it is closed, ensuring that the cover tightly covers the viewing port 110 and preventing the cover from accidentally opening during wear, thus improving the ease of use and reliability of the structure.

[0034] Reference Figure 2 In a further embodiment of the present invention, the edges of the other three sides of the inner surface of the shielding cloth 120 are detachably connected to the edges of the other three sides of the viewing port 110 via Velcro. The Velcro connection is simple and convenient; the user only needs to tear and stick to open and close the shielding cloth 120, without the need for complex fastening operations. Specifically, the left, right, and lower edges of the inner surface of the shielding cloth 120 are provided with Velcro tabs 121, and the left, right, and lower edges of the viewing port 110 are provided with Velcro tabs 111.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art.
