Description

Technical Field

[0001] This invention relates to the technical field of medical devices, specifically to an alternative chemical heating massage module. Background Technology

[0002] In recent years, self-heating physiotherapy products such as heat patches and moxibustion patches have been widely used in scenarios such as uterine warming for women, joint pain relief, and post-exercise recovery due to their portability, lack of power requirements, and comfortable temperature. However, these products have many technical and application defects: First, they are limited to static application and cannot be coordinated with the vibration function of modern physiotherapy equipment such as fascia guns. They can only act on the surface of the skin and it is difficult to achieve a combination of deep muscle relaxation and heat therapy. Second, the heating start-up is uncontrollable. It starts to react as soon as it is exposed to air after being unpacked, and there is no way to delay activation. It is easy to be accidentally triggered due to seal damage during transportation and storage, and the risk is higher in scenarios such as shared equipment and unattended terminals. Third, there is a lack of standardized interfaces and adapter structures, which cannot be fixed to fascia guns and make it difficult to form an efficient "equipment + consumables" usage mode. Fourth, traditional packaging requires an oxygen-free / inert environment, which is complex and costly. Moreover, the skin-applied design is rough and prone to local overheating burns or drug residue problems, which seriously limits the therapeutic depth and scenario adaptability of self-heating products. Summary of the Invention

[0003] The purpose of this invention is to provide an alternative chemical heating massage module to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an alternative chemical heating massage module, comprising:

[0005] A heating element, which is used to fit against the human body and generate heat;

[0006] The connecting part is located below the heating element;

[0007] A central rod is inserted into the heating part and the connecting part, and a triggering device is provided inside the central rod.

[0008] The docking part is used to connect with the fascia gun, and the docking part is provided with an adjustment component.

[0009] Preferably, the heating element includes a skin-friendly layer, a heat-conducting layer, a heat-insulating layer, and a sealed inner shell.

[0010] Preferably, the interior of the sealed inner shell is a heating chamber, which is filled with heating material. An initiation bag is provided inside the heating chamber, which is filled with an initiator. The top of the central rod extends to the bottom of the initiation bag.

[0011] Preferably, the heating material is composed of a main heating agent, a catalyst, an electrolyte, and a heat storage agent.

[0012] Preferably, the main heating agent is reduced iron powder, accounting for 60-70% by mass;

[0013] The catalyst is coconut shell charcoal, which is used to adsorb oxygen and moisture, increase the contact area between iron powder and reactants, accelerate the reaction start-up and maintain a constant temperature, and accounts for 15-20% by mass.

[0014] The electrolyte is sodium chloride, which dissolves in water to form an electrolyte solution, reducing the activation energy of the iron powder corrosion reaction and regulating the heating rate. Its mass percentage is 3-5%.

[0015] The heat storage agent is vermiculite, which expands after absorbing water, stores heat and releases it slowly, avoiding a sudden temperature rise in the initial stage of heating, and its mass percentage is 10-15%.

[0016] Preferably, the initiator is deionized water or a 5-10% sodium chloride aqueous solution.

[0017] Preferably, the triggering device is a guide rod that is slidably disposed inside the central rod. When the docking part is connected to the fascia gun, the axial pressure generated pushes the guide rod so that its sharp end pierces the trigger bag.

[0018] Preferably, the adjustment assembly includes two extension members that are movably inserted into the side wall of the docking part. The docking part is a welded assembly structure. An extension airbag is connected to the inner end of each extension member. A rotating ring is rotatably installed in the top surface of the docking part. A push plate is connected to the bottom of the rotating ring. A receiving cavity is provided in the docking part. The push plate is located in the receiving cavity and is connected to a compression airbag. One end of the compression airbag is fixed and is connected to the extension airbag through an air supply pipe. Two positioning pins are inserted into the rotating ring. A positioning hole is provided inside the part of the rotating ring that is embedded in the docking part. The bottom of the positioning pin is inserted into the positioning hole.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention proposes an alternative chemical heating massage module. First, the pressure-sensitive trigger device initiates heating through axial pressure at the fascia gun docking point, preventing accidental triggering and improving storage and transportation safety. Second, the docking part is equipped with an adjustment component to adapt to fascia guns of different diameters, combining vibration to achieve "heat + physical stimulation," enhancing deep muscle relaxation. Third, the layered materials, including a medical-grade skin-friendly layer and a directional heat-conducting layer, ensure safe use, preventing burns and residue. Fourth, the disposable design is hygienic; the entire module is discarded after use, eliminating the risk of contamination from the main unit, making it suitable for high-turnover scenarios such as gyms and physiotherapy clinics, significantly improving therapeutic effects and scenario applicability.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 3 This invention provides a technical solution: an alternative chemical heating massage module, comprising:

[0027] Heating element 1 is used to conform to the human body and generate heat. Heating element 1 includes a skin-friendly layer, a thermally conductive layer, a heat-insulating layer, and a sealed inner shell. The skin-friendly layer directly contacts human skin and must meet the core requirements of being non-toxic and non-irritating, soft and conforming, high-temperature resistant (constant temperature of 41-45℃, short-term tolerance to 50℃), and adaptable to vibration scenarios without falling off. It also needs to consider low cost and process compatibility for single use; medical-grade liquid silicone or spunbond nonwoven fabric composite PE film is recommended. The thermally conductive layer needs to enable directional heat conduction from the heating cavity to the skin-friendly layer, be thin (not exceeding 0.5mm), and be compatible with adjacent layers; aluminum foil composite thermally conductive film or flexible graphite film is recommended. The heat-insulating layer is located between the heating cavity and the sealed shell, and its core function is... To prevent heat loss from the heating chamber to the outside (non-skin-contact direction), ensuring directional heat conduction to the skin-contact layer, and maintaining a constant temperature (41-45℃) within the heating chamber for 15-20 minutes, while also meeting the requirements of low cost, lightweight, and easy processing for disposable consumables, expanded perlite or aerogel felt is recommended based on product structure and usage scenarios. The sealed inner shell needs to directly contact the main heating material (solid powders such as reduced iron powder and activated carbon) and the initiator (water or aqueous solution). Key requirements include resistance to chemical corrosion (resistance to electrolyte solutions), high temperature resistance (withstanding a constant temperature of 41-45℃, short-term 50℃), good sealing (no liquid / powder leakage), compatibility with compartmentalized packaging processes (to secure initiator pouches), and low cost (aligning with disposable consumable positioning). Based on product structure and usage scenarios, food-grade polypropylene or high-density polyethylene is recommended. The structure can be completed using conventional injection molding and heat sealing processes, suitable for industrial-scale disposable manufacturing.

[0028] The interior of the sealed inner shell is a heating chamber 14, which is filled with heating material. An initiation bag 12 is provided inside the heating chamber 14, which is filled with an initiator. The top of the central rod 3 extends to the bottom of the initiation bag 12.

[0029] The heating material is composed of a main heating agent, a catalyst, an electrolyte, and a heat storage agent. The main heating agent is reduced iron powder, accounting for 60-70% by mass; the catalyst is coconut shell charcoal, used to adsorb oxygen and moisture, increase the contact area between iron powder and reactants, accelerate the reaction initiation and maintain a constant temperature, accounting for 15-20% by mass; the electrolyte is sodium chloride, which dissolves in water to form an electrolyte solution, reduces the activation energy of the iron powder corrosion reaction, and regulates the heating rate, accounting for 3-5% by mass; the heat storage agent is vermiculite, which expands after absorbing water, stores heat and releases it slowly, avoiding a sudden temperature rise in the initial stage of heating, accounting for 10-15% by mass.

[0030] The initiator must be stable at room temperature, not react prematurely with the main heating material, mix rapidly after being punctured by the needle, initiate the reaction within 3-5 seconds, be non-corrosive, and be suitable for small bag packaging, such as PET / PE composite film bags, and be deionized water or 5-10% sodium chloride aqueous solution.

[0031] A connecting part 2 is connected below the heating part 1. A central rod 3 is inserted into the heating part 1 and the connecting part 2. A triggering device is provided inside the central rod 3. The triggering device is a guide rod 13 that is slidably set inside the central rod 3. The gun head integrates a pressure needle structure. When the docking part 4 is connected to the fascia gun, the axial pressure generated pushes the guide rod 13 so that its sharp end pierces the trigger bag 12. After the trigger bag 12 is pierced, the initiator and the heating material mix, triggering a heating reaction. The response speed is fast. When used with vibration, the temperature can rise to 41-45° in about 40 seconds. Through ratio control and structural optimization, a constant temperature output of 15-20 minutes can be achieved, covering the typical massage treatment cycle. It can support the expansion of medicated versions to form a heat + medicine linkage physiotherapy.

[0032] The bottom end of the center rod 3 is connected to a docking part 4, which is used to connect with the fascia gun. This is a common connection method. An adjustment component is provided on the docking part 4. The adjustment component includes two extension members 5, which are movably inserted into the side wall of the docking part 4. The docking part 4 is a welded assembly structure. An extension airbag 6 is connected to the inner end of the extension member 5. A rotating ring 7 is rotatably installed in the top surface of the docking part 4. A push plate 9 is connected to the bottom of the rotating ring 7. A receiving cavity is provided in the docking part 4. The push plate 9 is located in the receiving cavity and is connected to a compression airbag 10. One end of the compression airbag 10 is fixed and this end is connected to the extension airbag 6 through an air supply pipe 11. Two positioning pins 8 are inserted into the rotating ring 7. A positioning hole is provided inside the part of the rotating ring 7 that is embedded in the docking part 4. The bottom of the positioning pin 8 is inserted into the positioning hole. When connecting different fascia guns, the diameter of the docking part 4 to be adapted to be different. Therefore, the adjustment component can change the adaptation diameter of the docking part 4. By rotating the rotating ring 7, the push plate 9 compresses the compression airbag 10, which in turn causes the extension airbag 6 to expand and push the extension member 5 outward, so that the extended extension member 5 can be adapted to a fascia gun with a larger diameter.
