Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine physiotherapy equipment technology, and in particular relates to a traditional Chinese medicine hot compress physiotherapy instrument suitable for use by people with limited mobility. Background Technology

[0002] Traditional Chinese medicine (TCM) hot compress therapy relies on the principles of warming and medicinal penetration and meridian warming to relieve lower limb muscle spasms, promote blood circulation, and rehabilitate joints. It is widely used in the rehabilitation of conditions such as hemiplegic sequelae, lower limb muscle weakness, leg pain in the elderly, and stiffness in bedridden limbs, offering advantages such as safety, non-invasiveness, and suitability for long-term rehabilitation. Currently, most mainstream TCM leg hot compress therapy devices on the market are traditional integrated cylindrical or sleeve-type structures, including integrated sleeve-type hot compress devices, full-coverage therapy leg sleeves, and integrated bandage-type hot compress devices. While these devices can achieve basic leg hot compress therapy functions, their overall structural design is geared towards healthy individuals or users with normal mobility. They are not optimized for bedridden, hemiplegic, lower limb weakness, or limb movement disorders, and therefore cannot meet the rehabilitation needs of these special populations requiring independent therapy. Specific technical pain points are as follows: Existing tubular and sleeve-type hot ironing devices all adopt a closed, integrated sleeve structure. During use, users must independently complete a series of continuous limb movements, including raising the leg, aligning the leg with the sleeve, inserting the sleeve, and securing it with straps. However, bedridden paralyzed patients, hemiplegic patients, elderly patients with severe leg weakness, and postoperative mobility limitations generally suffer from insufficient lower limb muscle strength, inability to raise limbs independently, stiff joints with difficulty in flexion and extension, and loss of limb control. They are unable to independently complete the above-mentioned dressing operations and rely entirely on caregivers for manual assistance, increasing the burden on healthcare workers in homes, nursing homes, and rehabilitation institutions.

[0003] Therefore, developing a heat therapy device that is suitable for people with mobility impairments and does not require wearing is of significant clinical rehabilitation and market application value. Summary of the Invention

[0004] The purpose of this invention is to provide a traditional Chinese medicine hot compress therapy instrument suitable for use by people with limited mobility, in order to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0006] This invention relates to a traditional Chinese medicine hot compress therapy device suitable for use by people with mobility impairments. It includes a shovel-shaped base placed on both sides of a single leg. A semi-circular hot compress therapy unit is provided at the highest point of the shovel-shaped base. The shovel-shaped bases can be brought together to integrate the hot compress therapy units on both sides. During the process of the shovel-shaped bases bringing together, the single leg can be lifted along the inclined surface of the shovel and moved to the hot compress therapy unit.

[0007] Furthermore, one side of the bucket-type base is provided with a clearance opening, which is used to insert the bucket-type base on the other side when it approaches, so that the two bucket-type bases on both sides form an embedded fit.

[0008] Furthermore, the hot compress therapy unit includes: A semi-circular outer shell, which is integrally formed on the top of the bucket-type base; Airbags, the airbags being arranged circumferentially along the inner wall of the semi-circular outer shell; A medical-grade PET thermally conductive and insulating barrier inner layer, wherein the medical-grade PET thermally conductive and insulating barrier inner layer covers the surface of the airbag; A graphene electrothermal film, wherein the graphene electrothermal film covers the medical PET thermally conductive and insulating barrier inner layer; A medical-grade PET thermally conductive and insulating barrier outer layer, wherein the medical-grade PET thermally conductive and insulating barrier outer layer covers the graphene electrothermal film; A temperature-sensitive drug core layer, which is removably covered by the medical PET thermally conductive and insulating barrier outer layer; A constant temperature control module is disposed inside the bucket-shaped base and is electrically connected to the graphene heating film. An air pump, which is connected to the airbag.

[0009] Furthermore, the airbags are divided into odd-numbered airbags and even-numbered airbags, which are inflated alternately to create intermittent cyclic pressure on the leg area covered by the airbags.

[0010] Furthermore, the odd-numbered airbags are connected to the first inflation tube, the even-numbered airbags are connected to the second inflation tube, the air pump is connected to an air delivery tube, and the first inflation tube, the second inflation tube, and the air delivery tube are connected to a two-dimensional three-way solenoid valve.

[0011] Furthermore, multiple sets of NTC temperature sensors are disposed between the graphene electrothermal film and the medical PET thermally conductive insulating barrier outer layer, and the NTC temperature sensors are electrically connected to the constant temperature control module.

[0012] Furthermore, the temperature-sensitive drug core layer includes a silicone surface layer and a sustained-release carrier filled inside the silicone surface layer. The sustained-release carrier is made of a temperature-sensitive polymer hydrogel material with a minimum critical dissolution temperature (LCST) of 42°C. The sustained-release carrier uniformly embeds ultrafine powder of traditional Chinese medicine compound that has undergone low-temperature cell wall disruption chemical modification. The temperature-sensitive polymer hydrogel can undergo reversible molecular chain conformational changes with the working temperature of the graphene heating film. When the temperature is below 42°C, the molecular chains shrink and close, realizing low-speed sustained-release and locking of the active ingredients of traditional Chinese medicine. When the temperature is in the optimal therapeutic range of 42°C-48°C, the molecular chains fully expand and the porosity is maximized, realizing uniform and efficient release of the active ingredients of traditional Chinese medicine. When the temperature is above 48°C, it automatically shrinks the pores and limits the flow, inhibiting excessive volatilization of the active ingredients of traditional Chinese medicine, realizing temperature-responsive controlled-release drug.

[0013] Furthermore, the outer surface of the silicone surface layer is provided with a number of drug release micropores.

[0014] Furthermore, the medical PET thermally conductive insulating barrier outer layer is provided with a T-shaped pin hole, and the inner surface of the silicone surface layer is integrally formed with a T-shaped pin that matches the T-shaped pin hole.

[0015] Furthermore, the aforementioned herbal hot compress therapy instrument suitable for use by people with mobility impairments also includes a drive assembly for driving the two bucket-shaped bases to move closer to each other, and a fixing assembly for mounting and fixing the drive assembly to the bed.

[0016] The fixing components include a U-shaped clamp, the bottom plate of which has a threaded hole with an adjusting bolt threaded into it. The top of the adjusting bolt is integrally formed with a base plate. The U-shaped clamp is clamped to the side of the bed frame, and the adjusting bolt is rotated to press the base plate against the bottom surface of the bed frame, completing the locking and fixing. The top plate of the U-shaped clamp has a lifting rod, which includes an outer sleeve and an inner support rod. The inner support rod is inserted into the outer sleeve and secured with a locking bolt to maintain their height. The top of the outer support rod has an integrally formed U-shaped bearing bracket. The drive components include a drive shaft and a drive motor. The drive shaft is rotatably mounted on the U-shaped bearing bracket via bearings. The drive shaft has symmetrically arranged threads in opposite directions at both ends around its center. The two bucket-type bases are connected to the drive shaft via threaded bushings. A smooth shaft, fixedly connected to the U-shaped bearing bracket, is parallel to the bottom of the drive shaft. The two bucket-type bases are slidably connected to the smooth shaft via sliding sleeves. The drive motor is fixedly mounted on one side of the U-shaped bearing bracket and is connected to the threaded shaft via a coupling.

[0017] When using it for the first time, place the two bucket-shaped bases on both sides of the single leg, with the bucket-shaped bases in contact with the bed surface. Then, adjust the height of the lifting rod so that the U-shaped clamp can hold the side of the bed. Lock the U-shaped clamp with the adjusting bolts, then start the motor to drive the threaded shaft to rotate, so that the two bucket-shaped bases move closer together.

[0018] The present invention has the following beneficial effects.

[0019] Once the device is pre-positioned, subsequent treatments eliminate the need for caregivers to repeatedly assist patients with leg lifting, leg wrapping, and securing. Simply by driving the two bucket-shaped bases together, the device automatically lifts and supports the patient's lower limb using the inclined surfaces of the buckets, simultaneously closing the two semi-circular heat therapy units to form a complete enveloping cavity, automatically wrapping the leg and completing the treatment positioning. This device eliminates the need for manual wrapping required for traditional equipment, achieving automated, wear-free treatment. It is suitable for patients with hemiplegia, bedridden conditions, lower limb muscle weakness, or mobility impairments who cannot lift their limbs independently, allowing for rehabilitation treatment with minimal or no assistance. This significantly reduces the workload of manual caregivers in nursing homes, rehabilitation centers, and home-based care settings. Simultaneously, the two heat therapy units open and close synchronously with the bucket-shaped bases. After treatment, the bases separate, allowing for slow release of the lower limb without manual removal. The entire treatment process is simple and effortless, improving the convenience and willingness to use herbal heat therapy for people with mobility impairments, and better meeting the needs of long-term, continuous lower limb rehabilitation.

Detailed Implementation

[0032] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please see Figures 1 to 10 The present application provides a traditional Chinese medicine hot compress therapy device suitable for use by people with limited mobility, including shovel-shaped bases 1 located on the left and right sides of a patient's single leg; the two shovel-shaped bases 1 can approach each other, with one shovel-shaped base having a clearance opening 13, and the other shovel-shaped base can be inserted into the clearance opening 13 during the approach process to achieve embedded cooperation. The upper end of the shovel-shaped base 1 is integrally provided with a semi-circular hot compress therapy unit 2; during the approach process of the two shovel-shaped bases 1, on the one hand, the single leg in a lying position is automatically scooped up and lifted along its own shovel slope and transferred into the hot compress therapy unit 2, and on the other hand, the two semi-circular hot compress therapy units 2 are connected and merged to form a complete cylindrical wrapping cavity, realizing the encirclement and wrapping of the lower limb.

[0034] This instrument is also equipped with a drive component and a fixing component 4; the fixing component 4 is used to lock the entire instrument to the side of the bed, and the drive component is installed on the fixing component 4. The drive component is used to drive the two bucket-type bases on both sides to move closer to each other or separate from each other synchronously.

[0035] The fixing component 4 includes a U-shaped clamp 41. A threaded hole is drilled through the bottom plate of the U-shaped clamp 41, and an adjusting bolt 42 is fitted inside the threaded hole. A stop plate 45 is integrally installed at the upper end of the adjusting bolt 42. The U-shaped clamp 41 is snapped onto the side wall of the bed. Rotating the adjusting bolt 42 moves the stop plate 45 upwards to press against the bottom of the bed, thus locking and fixing the entire device. A lifting rod 43 is vertically mounted on the top plate of the U-shaped clamp 41. The lifting rod 43 includes an outer sleeve 431 and an inner support rod 432. The inner support rod 432 is slidably inserted into the outer sleeve 431. A locking bolt is fitted on the side wall of the outer sleeve 431. Tightening the locking bolt locks the extension height of the inner support rod 432, thereby adjusting the vertical height of the entire instrument. A U-shaped bearing bracket 44 is integrally formed at the top of the inner support rod 432.

[0036] The drive assembly includes a drive motor 31, a drive shaft 32, a coupling (not shown in the figure), and a guide shaft 33. The drive shaft 32 is rotatably mounted on a U-shaped bearing bracket 44 via bearings. The drive shaft 32 has opposite external threads machined at both ends, with the midpoint as the boundary. Threaded bushings 11 are fixed to both sides of the bucket-type base 1, and these bushings 11 engage with the two opposite threads of the drive shaft 32. The guide shaft 33 is arranged parallel to the drive shaft 32 and fixedly connected to the U-shaped bearing bracket 44. Sliding sleeves 12 are provided on both sides of the bucket-type base 1, slidingly fitted onto the outside of the guide shaft 33. The cooperation between the guide shaft 33 and the sliding sleeves 12 guides and limits the movement of the bucket-type base 1, preventing it from rotating with the drive shaft 32. The drive motor 31 is fixedly mounted on one side of the U-shaped bearing bracket 44, and the output shaft of the drive motor 31 is rigidly connected to the end of the drive shaft 32 via a coupling. During operation, the drive motor 31 drives the drive shaft 32 to rotate, and the two bucket-type bases 1 on both sides move synchronously towards each other or away from each other along the smooth shaft 33 by relying on the reverse threads at both ends.

[0037] Combination Figures 3 to 10The thermal therapy unit 2 comprises a semi-circular outer shell 21, airbags 22, a medical-grade PET thermally conductive and insulating inner layer 23, a graphene electrothermal film 24, a medical-grade PET thermally conductive and insulating outer layer 25, a temperature-sensitive drug core layer 26, a constant temperature control module, and an air pump. The semi-circular outer shell 21 is integrally formed and mounted on the top of the bucket-type base 1. Several airbags 22 are evenly arranged in a circumferential array on the inner wall of the semi-circular outer shell 21. The airbags 22 can be adapted to different leg shapes to a certain extent by varying degrees of inflation. The surface of the airbags 22 is covered with the medical-grade PET thermally conductive and insulating inner layer 23. The graphene electrothermal film 24 is attached to the side of the medical-grade PET thermally conductive and insulating inner layer 23 facing away from the airbags 22. The graphene electrothermal film 24 is covered with the medical-grade PET thermally conductive and insulating outer layer 25. The temperature-sensitive drug core layer 26 is detachably mounted on the outside of the medical-grade PET thermally conductive and insulating outer layer 25. The constant temperature control module and the air pump are both integrated and installed in the internal cavity of the bucket-type base 1; the graphene electric heating film 24 is electrically connected to the constant temperature control module, and the heating temperature is uniformly regulated by the constant temperature control module.

[0038] Multiple NTC temperature sensors 27 are arranged between the graphene heating film 24 and the medical PET thermally conductive insulating barrier outer layer 25. All NTC temperature sensors 27 are electrically connected to the constant temperature control module. The NTC temperature sensors 27 collect the surface temperature of the physiotherapy area in real time and feed it back to the constant temperature control module. The constant temperature control module dynamically adjusts the output power of the graphene heating film 24 according to the collected temperature to maintain the temperature of the physiotherapy area within a stable range of 42℃-48℃. It also has an overheat protection function to prevent local high temperature burns to patients.

[0039] All the airbags 22 arranged circumferentially inside the semi-circular outer shell 21 are divided into odd-numbered airbag groups and even-numbered airbag groups according to their arrangement order; all odd-numbered airbags are connected to the first inflation tube, and all even-numbered airbags are connected to the second inflation tube. The air pump is equipped with an air supply tube; the first inflation tube, the second inflation tube, and the air supply tube are all connected to a two-dimensional three-way solenoid valve. The two-dimensional three-way solenoid valve is connected to the overall control circuit of the machine, and alternately opens and closes the air path according to a preset timing sequence. Airbag working process: After the physiotherapy is started, the air pump continuously provides an air source, and the two-dimensional three-way solenoid valve controls the opening and closing of the air path in a timed manner; in the first stage, the odd-numbered airbag groups are inflated and the even-numbered airbag groups are depressurized and inflated, compressing the corresponding area of ​​the leg; in the next stage, the air path is switched, inflating the even-numbered airbag groups and depressurizing the odd-numbered airbag groups. By periodically inflating and deflating two sets of airbags, intermittent cyclic pressure is applied to the legs wrapped in the airbags. This provides rhythmic limb massage while applying heat, promoting blood circulation in the lower limbs and relieving limb stiffness and muscle spasms. It can also alleviate the problem of vascular compression and poor blood circulation caused by continuous pressure from traditional heat therapy devices.

[0040] In the above-mentioned configuration, each wire and conduit is laid along a pre-set wiring groove on the inner surface of the semi-circular outer shell 21 and extends to the internal cavity of the bucket-type base 1; a microcontroller is also installed inside the cavity. The microcontroller is electrically connected to the constant temperature control module 27 and the relay drive unit; the relay drive unit is electrically connected to the air pump 28 and the two-position three-way solenoid valve. The microcontroller sends temperature control commands to the constant temperature control module to adjust the ironing temperature, and at the same time controls the start and stop of the air pump and the on / off switching of the two-position three-way solenoid valve through the relay drive unit to realize the alternating inflation and deflation of the two sets of airbags. A control panel 28 is set on the surface of the bucket-type base 1 for controlling equipment operation, temperature setting, etc.

[0041] Meanwhile, the medical PET thermally conductive and insulating barrier outer layer 25 has T-shaped pin holes 251 at each of its four corners; the temperature-sensitive drug core layer 26 includes a silicone surface layer 261 and a sustained-release carrier 262 filled inside the silicone surface layer 261; several T-shaped pins 263 are integrally formed on the inner surface of the silicone surface layer 261, matching the T-shaped pin holes 251. The T-shaped pins 263 are forcefully inserted into the T-shaped pin holes 251 to achieve quick assembly and disassembly of the temperature-sensitive drug core layer, facilitating one-time use and replacement of the drug core, and preventing cross-infection. The silicone surface layer 261 has a large number of drug release micropores 264 on the side facing the patient's leg. The sustained-release carrier 262 is prepared using a temperature-sensitive polymer hydrogel with a minimum critical dissolution temperature (LCST) of 42℃, and the sustained-release carrier 262 uniformly embeds ultrafine powder of traditional Chinese medicine compound that has undergone low-temperature cell wall breaking chemical modification treatment. The thermosensitive polymer hydrogel possesses temperature-responsive reversible deformation characteristics: when the graphene electrothermal film 24 is heated to a temperature below 42℃, the hydrogel molecular chains shrink and the internal pores close, allowing for the slow and sustained release of active ingredients from traditional Chinese medicine and achieving drug lock-in; when the temperature is within the optimal therapeutic range of 42℃ to 48℃, the molecular chains fully expand, the material porosity reaches its maximum, and the effective ingredients of traditional Chinese medicine are released uniformly to the outside, acting on the human skin through the drug release micropores; when the temperature exceeds 48℃, the hydrogel automatically shrinks its pores to limit flow, inhibiting excessive volatilization of traditional Chinese medicine ingredients, while simultaneously assisting the temperature control system in providing early warning, achieving temperature-responsive controlled drug release and ensuring stable heat therapy effects.

[0042] In the above embodiments, the traditional Chinese medicine compound for rehabilitation, such as mugwort, safflower, angelica, chuanxiong, and lycopodium, is subjected to low-temperature cell wall breaking and ultra-fine pulverization to 200-300 mesh micro powder to remove coarse fiber impurities. The patented LCST=42℃ N-isopropylacrylamide thermosensitive polymer monomer is selected, and combined with crosslinking agent, initiator and medical purified water, and stirred to form a uniform and transparent precursor aqueous solution. It is a liquid fluid at room temperature (25℃) and has good encapsulation and penetration properties without coagulation and clumping. The pretreated ultrafine powder of traditional Chinese medicine was added to the gel precursor liquid at a mass ratio of 1:4. Vacuum homogenization and stirring process was used to eliminate air bubbles under negative pressure, so that the powder particles were evenly dispersed in the gel fluid. The well-mixed drug-gel mixture is injected into the drug core mold, and the polymerization and cross-linking reaction is initiated in a low-temperature and light-protected environment. It is then cured and molded at room temperature. After curing, the mixture is demolded, rinsed with purified water to remove residual monomers, and cut into flexible drug chips to form a sustained-release carrier, which is then filled into the silicone surface layer.

[0043] Based on the above, this application provides a traditional Chinese medicine hot compress therapy instrument suitable for use by people with limited mobility, and the specific method of use is as follows: S1. Initial Assembly and Positioning: Secure the U-shaped clamp 41 to the side of the bed, and tighten the bed frame by rotating the adjusting bolt 42. Start the drive motor 31 to separate the two bucket-type bases 1, creating space for placement. Loosen the locking bolts of the lifting rod 43, extend and retract the inner support rod 432 to adjust its height to suit the patient's leg height, and then lock it, ensuring that the two bucket-type bases are positioned on the left and right sides of the patient's single leg, with the bucket's inclined surface in contact with the bed surface. After the initial positioning adjustment is completed, subsequent physiotherapy does not require repeated disassembly and reassembly of the fixing components.

[0044] S2. Physiotherapy Positioning: The patient maintains a bed-lying position with the lower limbs naturally flat on the bed surface; the drive motor 31 is started, and the drive shaft 32 rotates to drive the two shovel-type bases 1 to move towards each other synchronously; the two shovel-type bases 1 rely on the inclined shovel surface to slowly lift and support the flat lower limbs, while the two semi-circular hot ironing physiotherapy units 2 on both sides connect and surround the legs, automatically completing the physiotherapy wrapping and positioning. The entire process does not require caregivers to lift or put on the limbs, and no straps are needed for fixation.

[0045] S3, Physiotherapy Operation: The graphene heating and airbag massage program is activated; the constant temperature control module drives the graphene electric heating film 24 to generate heat, and the heat is conducted layer by layer through each barrier layer to the temperature-sensitive drug core layer, and the release of traditional Chinese medicine is achieved by relying on the temperature-sensitive hydrogel; at the same time, the air pump and the two-dimensional three-way solenoid valve 223 work together to control the alternating inflation and deflation of odd-numbered airbag groups and even-numbered airbag groups, intermittently cyclically pressing the legs, and simultaneously carrying out traditional Chinese medicine hot ironing and rhythmic massage rehabilitation. The NTC temperature sensor continuously monitors the temperature to prevent burns.

[0046] S4. Treatment ends: After the preset treatment time is reached, the system stops heating and air supply to the airbags; the control drive motor reverses, the two bucket-type bases 1 separate from each other, the two hot ironing treatment units open, the legs naturally fall back to the bed, and the limbs can be removed directly without manual removal of the treatment equipment.

[0047] The above-described embodiments are merely preferred embodiments of the present invention and not limitations. Those skilled in the art should understand that the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention without departing from the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
