Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a split-type electrothermal traditional Chinese medicine treatment pack. Background Technology

[0002] Traditional Chinese medicine (TCM) hot compress is a time-honored therapy that involves applying heated medicinal herbs to specific areas of the body to achieve therapeutic effects such as warming the meridians, dispelling cold, relieving pain, and promoting blood circulation. Currently, a common method of hot compress in clinical treatment and home healthcare involves using a so-called "hot compress pack." This pack is typically made by medical professionals or patients themselves, who mix medicinal herbs with coarse salt containing properties that warm the meridians, promote blood circulation, resolve phlegm, and relieve coughs, and then place the mixture in a cloth bag. To use, the pack is heated in a microwave for several minutes and then applied while still hot to areas of pain or muscle soreness, or to the abdomen to relieve symptoms such as abdominal pain and constipation.

[0003] However, this traditional hot-curing herbal pack has many inconveniences and drawbacks in practical application. First, its preparation process is cumbersome, requiring manual cutting of the herbal bag, mixing, and repackaging each time it is used, resulting in low operational efficiency and difficulty in ensuring dosage consistency. Second, during repeated heating, the moisture and volatile active ingredients in the herbs are continuously lost, leading to a gradual decrease in efficacy. Simultaneously, the medicinal liquid that seeps out during heating easily penetrates the outer layer of the cloth bag, causing it to yellow and harden, which is not only unsightly but also easily soils the patient's clothing or bedding. More importantly, safety and temperature control issues are significant: the temperature of the herbal pack after microwave heating is extremely high and unevenly distributed, posing a high risk of burns during handling and application; the temperature cannot be effectively controlled or maintained throughout the entire use process, dropping rapidly over time, making it difficult to maintain a constant and effective treatment temperature, thus affecting the treatment effect and user experience.

[0004] Therefore, the present invention proposes a split-type electrothermal herbal treatment pack to at least partially solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a split-type electric heating Chinese medicine treatment pack, which solves the shortcomings of traditional hot pickling packs, such as cumbersome manual operation due to the inability to accurately control temperature, easy loss of medicinal efficacy due to repeated heating, uneven temperature distribution posing a risk of burns, and difficulty in maintaining a constant and effective treatment temperature.

[0006] The objective of this invention can be achieved through the following technical solution: a split-type electrothermal traditional Chinese medicine treatment pack, comprising: The flexible outer casing integrates the main controller; The liquid-storage heat-equalizing pad is detachably placed in the receiving cavity of the flexible outer jacket. It is a flat, sealed pad filled with a heat-conducting liquid medium. Its interior is provided with a biomimetic tree-shaped branching flow channel. The biomimetic tree-shaped branching flow channel has a graded structure and the flow cross-sectional area decreases step by step along the flow direction. A micro-circulating heating module, mounted on the flexible outer jacket and electrically connected to the main controller, includes a micro water pump and a heater; A self-sealing circulation pipeline connects the micro-circulation heating module and the liquid-storage heat-equalizing pad to form a circulation loop for the heat-conducting liquid medium. A breathable medicated core pack is detachably attached to the human-facing surface of the liquid-retaining heat-equalizing pad, and contains a traditional Chinese medicine composition. The liquid-storage heat-equalizing pad is equipped with a temperature sensor that is electrically connected to the main controller. The main controller stores a multi-stage temperature control program, which includes a preheating stage, a constant temperature penetration stage, and a cooling and soothing stage that are executed sequentially according to a set time sequence and temperature parameters. The main controller performs closed-loop control of the power of the heater and the speed of the micro water pump based on the real-time data from the temperature sensor, so as to adjust the temperature of the heat-conducting liquid medium and thereby uniformly heat the drug core pack.

[0007] As a preferred technical solution of the present invention, the diameters of each level of the biomimetic tree-shaped branching flow channel satisfy Murray's law, that is, the cube of the diameter of the main channel is equal to the sum of the cubes of the diameters of each sub-channel; and in the low flow rate range of 0.1-0.5L / min, the steady-state temperature difference between any two points on the surface of the liquid-storage heat-equalizing pad facing the human body is ≤±1.5℃.

[0008] As a preferred embodiment of the present invention, the multi-stage temperature control program specifically includes: Preheating stage: The temperature of the heat-conducting liquid medium is raised from room temperature to 42-45°C at a heating rate of 3-5°C / min for 2-3 minutes to dilate skin pores and stimulate local blood circulation; Thermostatic penetration stage: The temperature is maintained at 52±1℃ for 20-30 minutes. This temperature range is the temperature range in which the cumulative penetration of the characteristic active ingredients in the traditional Chinese medicine composition reaches its peak, as determined by in vitro transdermal experiments. Cooling and soothing phase: The temperature of the heat-conducting liquid medium is reduced to 35-38℃ at a cooling rate of 1-2℃ / min for 5-8 minutes to shrink pores and avoid discomfort caused by excessive temperature difference.

[0009] As a preferred embodiment of the present invention, the main controller calls the multi-stage temperature control program according to the type of drug core pack selected by the user through the operation button, and uses a PID algorithm to perform closed-loop feedback dynamic adjustment of the micro-circulating heating module. Combined with the uniform flow distribution characteristics of the biomimetic tree-shaped branched flow channel, the heating temperature control accuracy of the drug core pack reaches ±0.5℃.

[0010] As a preferred embodiment of the present invention, a self-sealing quick connector is provided at the connection between the self-sealing circulation pipeline and the liquid-storage heat-equalizing pad, for detachably connecting the liquid-storage heat-equalizing pad and the micro-circulation heating module.

[0011] As a preferred embodiment of the present invention, the flexible outer jacket comprises, from the outside to the inside, a waterproof and oil-resistant composite fabric outer layer and a smooth heat-insulating inner layer; the breathable medicated core pack is made of a non-woven fabric material with high moisture permeability and leak-proof properties.

[0012] As a preferred embodiment of the present invention, the breathable medicine core pack contains traditional Chinese medicine powder, and the medicine core pack also contains coarse salt particles to assist in heat storage and moisture retention.

[0013] As a preferred embodiment of the present invention, the main controller includes an overheat protection module. When the temperature sensor detects that the temperature of the heat-conducting liquid medium exceeds 65°C, the power supply to the micro-circulating heating module is automatically cut off and an audible and visual alarm is issued.

[0014] As a preferred embodiment of the present invention, the flexible jacket is further provided with a touch screen that is electrically connected to the main controller for displaying real-time temperature, working mode and remaining time.

[0015] As a preferred embodiment of the present invention, the liquid-storing heat-equalizing pad is made of flexible medical-grade silicone or thermoplastic polyurethane material, and the biomimetic tree-shaped branching channels are integrally molded inside the liquid-storing heat-equalizing pad.

[0016] The beneficial effects of this invention are as follows: By adopting a split-structure design, a detachable liquid-storage heat-equalizing pad is combined with a breathable medicated core pack, completely solving the problems of traditional hot compress packs requiring manual filling, easy attenuation of efficacy, and easy staining of clothing. This achieves convenient replacement of the medicated core and single-use, ensuring the stability of efficacy and hygiene in each treatment. Its core lies in the fact that by setting a biomimetic tree-like branching flow channel conforming to Murray's law inside the liquid-storage heat-equalizing pad, combined with the closed-loop control of the micro-circulating heating module, it can achieve extremely uniform heating with a temperature difference of no more than ±1.5℃ between any two points on the surface at low flow rates. Furthermore, in conjunction with the multi-stage temperature control program pre-stored in the main controller, it can precisely execute different medicated cores. The device features a personalized treatment curve that integrates preheating, constant-temperature penetration, and cooling for soothing effects. In particular, the constant-temperature phase is precisely controlled at the optimal penetration temperature of 52±1℃, as determined by in vitro transdermal experiments. Combined with a PID algorithm, this achieves high-precision temperature control of ±0.5℃, thereby maximizing the transdermal absorption rate of the effective components of traditional Chinese medicine and significantly improving the treatment effect. Furthermore, the device allows for tool-free quick assembly and disassembly of the heat-distributing pad through a self-sealing quick connector. The waterproof and oil-resistant outer casing and leak-proof medicine core pack ensure safe and clean use. It also integrates overheat protection and a touch display. While providing an intelligent and precise thermotherapy experience, it greatly reduces the risk of burns, achieving efficient, safe, comfortable, and hygienic traditional Chinese medicine moist heat therapy.

[0019] Figure 2 This is a schematic diagram of the exploded three-dimensional structure of the cavity containing the flexible jacket of the present invention.

[0020] In the diagram: 100, flexible outer jacket; 101, receiving cavity; 200, micro-circulating heating module; 300, liquid-storage heat-equalizing pad; 400, self-sealing circulation pipeline; 500, breathable drug core pack; 600, touch screen display. Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0022] Please see Figures 1-2This embodiment provides a split-type electrothermal herbal medicine treatment pack, which mainly consists of five core parts: a flexible outer jacket 100, a liquid-storage heat-equalizing pad 300, a micro-circulating heating module 200, a self-sealing circulation pipeline 400, and a breathable medicine core pack 500. The treatment pack adopts a split design, with each component connected in a detachable manner, ensuring both ease of use and convenient cleaning and replacement of consumables.

[0023] The flexible jacket 100 serves as the base of the entire device, and its interior contains a cavity 101 for holding the liquid-storage heat spreader 300. A micro-circulating heating module 200 is fixedly installed on one side of the flexible jacket 100, and a touch screen 600 is electrically connected to the main controller via flexible leads; the main controller is built into the flexible jacket 100 and is electrically connected to various functional modules via wires.

[0024] The Flexible Jacket 100 features a double-layer composite structure design, consisting of an outer layer of waterproof and oil-resistant composite fabric and an inner layer of smooth thermal insulation. The outer layer is made of a polyester fiber composite material with wear-resistant and stain-resistant properties, effectively preventing liquid leakage and oil contamination during use; the inner layer uses a soft silicone thermal insulation layer, ensuring both good thermal insulation and a comfortable feel.

[0025] One side of the flexible jacket 100 is equipped with a touch screen 600, which displays key information such as the current treatment temperature, working mode, and remaining time in real time. The touch screen 600 is electrically connected to the main controller built into the flexible jacket 100 via flexible leads, enabling data display and command input functions. As a supplement and backup to the touch operation, three physical operation buttons are also located below the display: a power button, a mode selection button, and an confirmation button. These buttons are also connected to the main controller via leads, ensuring convenient operation even under special circumstances (such as when wearing gloves or when the screen is dirty).

[0026] The liquid-storage heat spreader 300 is the core component for achieving uniform heating. Made of flexible medical-grade silicone, it features a flat, sealed pad structure that ensures both excellent flexibility and conformability while withstanding long-term thermal cycling. The pad body is made of fatigue-resistant silicone and has undergone pressure cycle testing, demonstrating a service life of at least 500 cycles. The pad is filled with a thermally conductive liquid medium, preferably medical-grade mineral oil, which exhibits good thermal stability and fluidity, and can operate within a temperature range of 20-80℃.

[0027] The liquid-storage heat spreader 300 features a biomimetic tree-like branching flow channel. This channel is manufactured using a one-piece molding process and has a hierarchical structure with the flow cross-sectional area decreasing progressively along the flow direction. The flow channel design strictly adheres to Murray's Law, which states that the cube of the diameter of the main channel is equal to the sum of the cubes of the diameters of all the sub-channels. The mathematical expression is: Where D is the diameter of the main pipe and d_i is the diameter of each sub-pipe. Through this optimized design, within a low flow rate range of 0.1-0.5 L / min, the steady-state temperature difference between any two points on the human-facing side of the liquid-storage heat spreader 300 can be controlled within ±1.5℃. Actual testing showed that at a flow rate of 0.3 L / min, the maximum steady-state temperature difference measured using a 9-point temperature measurement method on the pad surface was 1.2℃, ensuring highly uniform heating.

[0028] Two NTC temperature sensors, with an accuracy of ±0.3℃, are embedded at the edge of the liquid-storage heat spreader 300. These sensors are used to detect the surface temperature of the pad and the temperature of the internal heat-conducting medium, respectively. The sensors are connected to the main controller via wires to achieve real-time acquisition and feedback of temperature signals.

[0029] The miniature circulating heating module 200 mainly consists of a miniature water pump, a PTC heater, and a heat sink. The miniature water pump is driven by a brushless DC motor, with an adjustable flow rate of 0.1-0.5 L / min, an operating voltage of 12V, and a maximum power consumption of no more than 8W. The PTC heater has a rated power of 50W and uses a ceramic heating element with a positive temperature coefficient, featuring rapid heating and automatic temperature control. This module is secured to the rear side of the flexible outer casing 100 using a combination of Velcro and a zippered pocket, ensuring a stable connection while facilitating user disassembly and maintenance.

[0030] The miniature circulating heating module 200 is connected to the liquid-storage heat-spreading pad 300 via a self-sealing circulation pipeline 400, forming a closed circulation loop. During operation, a miniature water pump extracts the heat-conducting medium from the liquid-storage heat-spreading pad 300 and sends it to the PTC heater for heating. The heated medium then returns to the liquid-storage heat-spreading pad 300 via a return pipeline, achieving continuous heat transfer.

[0031] The self-sealing circulation tubing 400 is made of medical-grade silicone tubing, possessing excellent flexibility and temperature resistance. Both ends of the tubing connect to the miniature circulating heating module 200 and the liquid-storage heat spreader 300, respectively, with a self-sealing quick-connect fitting at the connection point. This fitting features a push-in design with a built-in one-way valve and sealing ring. When the liquid-storage heat spreader 300 needs to be removed, simply press the release button on the fitting to easily pull it out, simultaneously closing the internal valve to prevent leakage of the heat transfer medium.

[0032] The breathable medicine core pack 500 is made of composite non-woven fabric, with its outer layer exhibiting high moisture permeability (≥5000g / m²·24h). To prevent leakage of powder and saline solution, the core pack utilizes a non-woven fabric composite porous PE film structure, and the edges are treated with an ultrasonic hot-press sealing process to ensure effective encapsulation of the contents. The core pack contains a traditional Chinese medicine composition, comprising powdered herbs with properties protected by a patent for warming the meridians, promoting blood circulation, resolving phlegm, and relieving cough, as well as an appropriate amount of coarse salt granules. The coarse salt granules serve to assist in heat retention and maintain appropriate humidity, facilitating the release and penetration of the effective components of the traditional Chinese medicine.

[0033] The breathable medicated pad 500 is detachably attached to the human-facing surface of the liquid-retaining heat-spreading pad 300 via a Velcro structure. The hook side of the Velcro is sewn to the four corners of the medicated pad, while the loop side is fixed to the corresponding position on the liquid-retaining heat-spreading pad 300. This design makes it very convenient to replace the medicated pad, allowing users to replace it with a new one as needed.

[0034] The split-type electrothermal herbal medicine treatment pack of this invention uses a closed-loop control method to achieve precise heating of the medicine core pack. The main controller, as the core of the system, dynamically adjusts the heater power and water pump speed of the micro-circulating heating module 200 based on real-time data collected by the temperature sensor and through a PID (proportional-integral-derivative) algorithm, thereby precisely controlling the temperature of the heat-conducting liquid medium and ultimately achieving uniform humid heat heating of the breathable medicine core pack 500.

[0035] The main controller stores a multi-stage temperature control program. Users can select different drug cartridge types via the touchscreen display or physical operation buttons, and the system will automatically call the corresponding temperature control program. This multi-stage temperature control program executes the preheating stage, the constant-temperature penetration stage, and the cooling and soothing stage sequentially according to the set time sequence and temperature parameters. The specific parameters for each stage are as follows:

[0036] The temperature for the isothermal permeation phase was set at 52±1℃, and this optimal temperature range was determined through in vitro transdermal experiments. The Franz diffusion cell method was used, with isolated mouse skin as the transdermal barrier and a phosphate-buffered saline solution at pH 7.4 as the receiving solution. In the experiment, the 24-hour cumulative permeation of ferulic acid, the characteristic active ingredient in the traditional Chinese medicine composition, was measured under five constant temperature conditions: 48℃, 50℃, 52℃, 54℃, and 56℃. The results showed that the cumulative permeation of ferulic acid reached its peak at 52℃, at 156.4 μg / cm², which was significantly higher than the 112.1 μg / cm² at 48℃ and the 135.8 μg / cm² at 56℃ (p<0.05). Therefore, 52±1℃ was determined as the optimal permeation temperature range. The system uses a PID algorithm combined with the uniform flow distribution characteristics of a biomimetic tree-shaped branching channel to achieve a heating temperature control accuracy of ±0.5℃ for the drug core pack, ensuring the stability and reliability of the treatment effect.

[0037] To ensure safe use, the split-type electrothermal herbal medicine treatment pack of this invention integrates multiple safety protection mechanisms. The main controller has a built-in overheat protection module. When the temperature sensor detects that the temperature of the heat-conducting liquid medium exceeds 65°C, the system will automatically cut off the power supply to the micro-circulating heating module 200, display a fault code on the touch screen 600, and emit a continuous buzzer alarm sound until the fault is resolved.

[0038] In addition, the system features overcurrent protection, short-circuit protection, and undervoltage protection. Overcurrent protection is triggered immediately when the current in the circuit exceeds 2A; undervoltage protection activates an alarm and stops heating when the voltage drops below 10V. These protective circuits quickly cut off the power supply to prevent equipment damage or safety accidents. The flexible outer jacket 100 uses a waterproof and oil-resistant composite fabric that effectively prevents liquid from seeping into the internal circuitry, further enhancing safety during use.

[0039] The invented split-type electrothermal herbal therapy pack is simple and convenient to use: First, take out the new breathable herbal core pack 500 from the packaging, peel off the protective film on the back, and fix it directly to the surface of the liquid-storing heat-dissipating pad 300, which is placed inside the flexible outer jacket 100, using Velcro; then, apply the flexible outer jacket 100 to the area where the patient needs treatment (such as areas of pain or muscle soreness, abdomen, etc.), which can be used directly on the skin or through a thin layer of clothing; after turning on the device by pressing the power button, select the treatment mode corresponding to the herbal core pack using the touch display 600 or physical operation buttons, and the system will automatically start the multi-stage temperature control program. The user can monitor the treatment temperature and remaining time in real time through the display screen; after the treatment program is completed, the system will automatically stop heating and issue a prompt sound. At this time, turn off the power and remove the therapy pack. Finally, tear off the used breathable herbal core pack 500 from the liquid-storing heat-dissipating pad 300 and discard it.

[0040] This invention, while retaining the advantages of traditional Chinese medicine hot compress therapy, effectively solves many of the shortcomings of traditional hot compress packs: It adopts a split structure and a standardized breathable medicine core pack 500, which not only eliminates the tedious steps of manually cutting and bagging medicine, but also avoids the problem of medicine loss caused by repeated heating, ensuring the stability and consistency of the medicine's efficacy in each treatment; by setting a biomimetic tree-shaped branching flow channel inside the liquid-storing heat-equalizing pad 300 and combining it with a closed-loop temperature control system, it achieves uniform moist heat heating of the treatment surface, solving the problem of uneven temperature distribution in traditional hot compresses; at the same time, multiple safety protection mechanisms and precise temperature control technology effectively avoid the risk of burns, and the waterproof and oil-proof outer cover and leak-proof medicine core pack design further solve the hygiene problem of staining clothing; more importantly, through multi-stage temperature control programs and optimal penetration temperature control verified by in vitro transdermal experiments, it maximizes the transdermal absorption rate of the effective components of Chinese medicine, significantly improving the therapeutic effect and providing users with an efficient, safe, comfortable, and hygienic Chinese medicine moist heat therapy solution.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
