Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a heating device for external application of traditional Chinese medicine. Background Technology

[0002] A heating device for external application of traditional Chinese medicine is a device specifically designed for use with external application of traditional Chinese medicine. Its core function is to provide a suitable temperature for externally applied traditional Chinese medicine (such as herbal packs, ointments, and patches) through a controllable heating method, so as to enhance the transdermal absorption of traditional Chinese medicine, promote local blood circulation, and thus improve the therapeutic efficacy of externally applied traditional Chinese medicine.

[0003] In the clinical nursing of general surgery using traditional Chinese medicine, external application of Chinese herbal medicine is a common treatment method, and its efficacy is closely related to the temperature of the medicine. Currently, the heating devices used in clinical practice have low temperature control precision, making it difficult to ensure that the Chinese herbal medicine exerts its therapeutic effect at the optimal temperature, thus affecting the treatment outcome. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a heating device for external application of traditional Chinese medicine, which can achieve precise temperature control so that the medicine can exert its therapeutic effect at the optimal temperature.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A heating device for external application of traditional Chinese medicine includes: a main frame and a heating device; the main frame has multiple drug placement slots on one side for fitting the patient; the multiple drug placement slots are spaced apart; the heating device is installed on the main frame, and the heating device includes multiple heating films, multiple temperature detection components, a battery, and a control module; the multiple heating films are correspondingly installed in one of the drug placement slots, and the heating films are used to heat the drugs in the drug placement slots; the multiple temperature detection components are correspondingly installed in one of the drug placement slots, and the temperature detection components are used to detect the temperature of the drugs in the drug placement slots; the heating films, the temperature detection components, and the battery are all electrically connected to the control module.

[0007] Furthermore, the main frame is made of flexible silicone material.

[0008] Furthermore, the heating film is a graphene heating film.

[0009] Furthermore, the drug placement slot has a accommodating space, and the direction perpendicular to the depth of the drug placement slot is a first direction, the accommodating space extends along the first direction; the temperature detection component includes a driving device and a temperature sensor, the driving device is installed in the accommodating space, the output of the driving device is connected to the temperature sensor, supports the temperature sensor, and is used to drive the temperature sensor closer to the drug.

[0010] Furthermore, the temperature sensor is positioned close to the drug.

[0011] Furthermore, the temperature sensor is an NTC high-precision thermistor.

[0012] Furthermore, the main frame is connected to both ends with Velcro straps.

[0013] Furthermore, the Velcro strap has multiple ventilation holes, which are distributed at intervals.

[0014] Furthermore, the Velcro strap is connected to an abrasion-resistant plate, and the abrasion resistance of the abrasion-resistant plate is greater than that of the Velcro strap.

[0015] Furthermore, the abrasion-resistant sheet is sewn onto the Velcro strap.

[0016] Furthermore, the heating device also includes a temperature alarm device, which is used to issue an audible and visual alarm when the temperature is abnormal. The temperature alarm device is electrically connected to the battery and the control module.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The main frame has multiple drug placement slots on one side for fitting the patient; these slots are spaced apart; multiple heating films are correspondingly installed in one of the drug placement slots, and each heating film heats the drug within its slot. The spaced-apart drug placement slots provide precise mounting positions and independent heating spaces for the heating films, ensuring each film has its own dedicated heating area. Patients do not need to adjust the position of the Chinese medicine during use; each heating film can heat the corresponding medicine in its slot independently. This one-to-one correspondence allows different Chinese medicines or medicines from different parts of the same patient to simultaneously reach their appropriate temperatures, achieving precise temperature control and ensuring the medicine exerts its therapeutic effect at the optimal temperature.

[0019] 2. The main frame has multiple drug placement slots on one side for contact with the patient; these slots are spaced apart; multiple temperature detection components are installed in one of the drug placement slots, each detecting the temperature of the medicine within. The spaced-out slots define clear detection ranges and independent working areas for the temperature detection components, with each component corresponding to a dedicated drug temperature measurement area. During device operation, no adjustment of the detection components is required; each component can accurately detect the temperature of the corresponding Chinese medicine in its slot. This setup allows for simultaneous and accurate detection of the temperatures of different Chinese medicines or Chinese medicines from different parts of the same patient, providing a precise basis for the control module to regulate heating, thereby achieving precise temperature control and ensuring that each Chinese medicine exerts its therapeutic effect at the optimal temperature.

[0020] 3. The heating film, temperature detection component, and battery are all electrically connected to the control module. This configuration ensures that the battery provides stable power to the heating film and temperature detection component, guaranteeing continuous operation of all components. The temperature detection component transmits real-time drug temperature data to the control module, which then precisely adjusts the heating film's state accordingly: if the temperature is too low, heating is activated or intensified; if it is too high, heating is stopped or reduced. This connection avoids the problems of separation between heating and detection, and delayed regulation, common in traditional devices. It enables rapid and coordinated detection, transmission, and regulation, achieving precise control of drug temperature and ensuring that the drug exerts its therapeutic effect at the optimal temperature.

[0028] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See Figures 1-5 A preferred embodiment of the present invention provides a heating device for external application of traditional Chinese medicine, comprising: a main frame 1 and a heating device 2; the main frame 1 has a plurality of drug placement slots 11 on one side for fitting the patient; the plurality of drug placement slots 11 are spaced apart; the heating device is installed on the main frame 1, and the heating device 2 includes a plurality of heating films 21, a plurality of temperature detection components 22, a battery 23 and a control module 24; the plurality of heating films 21 are correspondingly installed in one of the drug placement slots 11, and the heating films 21 are used to heat the drugs in the drug placement slots 11; the plurality of temperature detection components 22 are correspondingly installed in one of the drug placement slots 11, and the temperature detection components 22 are used to detect the temperature of the drugs in the drug placement slots 11; the heating films 21, the temperature detection components 22 and the battery 23 are all electrically connected to the control module 24.

[0031] When using the external application heating device for traditional Chinese medicine, the herbs to be applied are first placed in multiple medicine placement slots 11 on the side of the main frame 1 that are in contact with the patient. These slots are spaced apart and can each hold different herbs, meeting the needs of applying medicine to multiple areas. The heating device 2, installed on the main frame 1, begins operation. The heating film 21, corresponding to each medicine placement slot 11, activates to heat the herbs within. The power required for heating is provided by the battery 23, which provides energy support for the entire heating device 2. As heating progresses, the temperature detection components 22, also corresponding to each medicine placement slot 11, begin to function, monitoring the temperature of the herbs in the slots in real time. Since the efficacy of traditional Chinese medicine is closely related to temperature, excessively high or low temperatures can affect its effectiveness. When the temperature of the herbs changes, the temperature detection components 22 can promptly capture this temperature information. The control module 24, electrically connected to the heating film 21, the temperature detection components 22, and the battery 23, receives the temperature data transmitted by the temperature detection components 22. The control module 24 internally presets a temperature range within which the traditional Chinese medicine (TCM) exerts its optimal therapeutic effect. It compares and analyzes the real-time detected temperature with this preset range. If the detected temperature is below the preset range, the control module 24 instructs the heating film 21 to continue heating or increase the heating power; if the detected temperature reaches or exceeds the preset range, the control module 24 controls the heating film 21 to reduce the heating power or stop heating. Through the real-time regulation of the heating film 21 by the control module 24 and the continuous monitoring by the temperature detection component 22, it is ensured that the TCM in each medicine placement tank 11 is kept within the optimal temperature range, allowing the medicine to fully exert its therapeutic effect at a suitable temperature, thus achieving precise temperature control.

[0032] Obviously, multiple drug placement slots 11 are provided on the side of the main frame 1 that is used to fit the patient; the multiple drug placement slots 11 are arranged at intervals; multiple heating films 21 are correspondingly installed in one of the drug placement slots 11, and the heating films 21 are used to heat the drugs in the drug placement slots 11. The multiple spaced drug placement slots 11 provide precise installation positions and independent heating spaces for the heating films 21, so that each heating film 21 corresponds to a dedicated heating area. When using the drug, the patient does not need to adjust the position of the Chinese medicine, and each heating film 21 can heat the Chinese medicine in its corresponding slot separately. This one-to-one correspondence layout allows different Chinese medicines or Chinese medicines from different parts of the same patient to simultaneously obtain their appropriate temperature, achieving precise temperature control and ensuring that the drugs exert their therapeutic effect at the optimal temperature. Multiple drug placement slots 11 are provided on the side of the main frame 1 that is used to fit the patient; the multiple drug placement slots 11 are arranged at intervals; multiple temperature detection components 22 are correspondingly installed in one of the drug placement slots 11, and the temperature detection components 22 are used to detect the temperature of the drugs in the drug placement slots 11. Multiple separate drug placement slots 11 clearly define the detection range and independent working area for the temperature detection component 22, with each component corresponding to a dedicated drug temperature measurement zone. During device operation, no adjustment of the detection components is required; each component can accurately detect the temperature of the corresponding Chinese medicine in its slot. This setup allows for simultaneous and accurate detection of the temperatures of different Chinese medicines or Chinese medicines from different parts of the same patient, providing a precise basis for the control module 24 to regulate heating, thereby achieving precise temperature control and ensuring that each Chinese medicine exerts its therapeutic effect at the optimal temperature. The heating film 21, the temperature detection component 22, and the battery 23 are all electrically connected to the control module 24. The battery 23 provides stable power to the heating film 21 and the temperature detection component 22, ensuring continuous operation of all components. The temperature detection component 22 transmits real-time drug temperature data to the control module 24, which then precisely adjusts the state of the heating film 21 accordingly: if the temperature is too low, heating is activated or intensified; if the temperature is too high, heating is stopped or weakened. This connection avoids the problems of separation between heating and detection and lag in regulation in traditional devices, enabling rapid coordination of detection, transmission, and regulation, achieving precise control of drug temperature, and ensuring that the drug exerts its therapeutic effect at the optimal temperature.

[0033] Preferably, in this embodiment, the main frame 1 is made of flexible silicone material. This design, due to the excellent flexibility and elasticity of the flexible silicone material, allows it to adapt to the contours of different parts of the patient's body. Whether conforming to curved areas such as joints and the torso, or responding to slight movements during use, it maintains close contact with the skin, preventing gaps or loose fits caused by excessive frame rigidity. This ensures that the traditional Chinese medicine in the drug placement slot 11 can stably act on the affected area. The silicone material is soft and gentle to the touch, avoiding harsh friction or pressure when in contact with the skin, reducing skin irritation, and is especially suitable for scenarios requiring prolonged medication application. Simultaneously, silicone has good biocompatibility, minimizing the likelihood of skin allergies or other adverse reactions, improving patient comfort and safety. Furthermore, the flexible silicone material possesses certain temperature resistance and stability. During the operation of the heating device 2, it can withstand the temperature generated by the heating film 21 without deformation, aging, or releasing harmful substances due to temperature changes, ensuring the overall lifespan and safety of the device and indirectly providing stable structural support for the medication to exert its therapeutic effect at an appropriate temperature.

[0034] Preferably, in this embodiment, the heating film 21 is a graphene heating film. Graphene heating films possess excellent electrical and thermal conductivity, enabling rapid heating upon energization and exhibiting strong uniformity in heating, thus avoiding the problems of excessively high local temperatures or uneven heating inherent in traditional heating elements. This means that the traditional Chinese medicine in the drug placement tank 11 can be rapidly and uniformly heated to quickly reach the appropriate temperature for therapeutic efficacy, while reducing the risk of damage to drug components due to localized overheating. Furthermore, the graphene heating film has a fast thermal response speed, allowing it to react quickly to the control commands of the control module 24. When the control module 24 issues a command to adjust the heating power based on feedback from the temperature detection component 22, the graphene heating film can quickly change its heating state, promptly raising or lowering the temperature to ensure that the drug temperature remains stable within the optimal range, further improving the accuracy of temperature control. In addition, the graphene heating film is thin, light and flexible, which can better fit the main frame 1, conform to the shape of the drug placement slot 11, and even adapt to the patient's body contour along with the frame. This ensures the uniformity of the heating effect and does not affect the overall fit of the device and the patient's comfort due to its own hard material. It provides a guarantee for the drug to exert its therapeutic effect at the optimal temperature from multiple dimensions.

[0035] Preferably, in this embodiment, the drug placement slot 11 has a receiving space 111, with the direction perpendicular to the depth of the drug placement slot 11 being a first direction, and the receiving space 111 extending along the first direction; the temperature detection component 22 includes a driving device 221 and a temperature sensor 222, the driving device 221 being installed in the receiving space 111, the output of the driving device 221 being connected to the temperature sensor 222 and supporting the temperature sensor 222, and being used to drive the temperature sensor 222 closer to the drug. This arrangement of the receiving space 111 extending along the first direction provides ample space for the driving device 221 to move the temperature sensor 222, allowing the temperature sensor 222 to approach the drug over a wider range. Since different drugs may have different shapes and placement positions, the driving device 221 can adjust the position of the temperature sensor 222 according to the actual situation, making it closer to the surface or interior of the drug, avoiding deviations between the detected temperature and the actual drug temperature due to excessive distance, thereby significantly improving the accuracy of temperature detection. Furthermore, the drive device 221 can flexibly adjust the proximity of the temperature sensor 222 to different forms of traditional Chinese medicine, ensuring accurate temperature detection regardless of the medicine's state. This solves the problem of the traditional temperature detection component 22 having a fixed position and being difficult to adapt to the detection needs of different medicines. It allows the temperature detection component 22 to better cooperate with various externally applied traditional Chinese medicines, providing accurate temperature data to the control module 24, thereby ensuring that the medicine always exerts its therapeutic effect at the optimal temperature. Simultaneously, the design of the drive device 221 supporting the temperature sensor 222 ensures the stability of the temperature sensor 222 during movement, avoiding the influence of shaking or other factors on the detection results, further ensuring the reliability of temperature detection and laying a solid foundation for the precise temperature control of the entire device. The drive device 221 can be a miniature electric telescopic rod or an electromagnetic drive rod.

[0036] Preferably, in this embodiment, the temperature sensor 222 is an NTC high-precision thermistor. NTC high-precision thermistors have extremely high sensitivity and measurement accuracy, capable of capturing minute changes in drug temperature. In external application of traditional Chinese medicine, the temperature range within which the drug achieves optimal efficacy is often narrow; even a deviation of 1-2°C can affect the efficacy. NTC high-precision thermistors can control temperature detection errors within a very small range, ensuring that the temperature data fed back to the control module 24 is accurate and reliable, providing a precise basis for temperature control. Furthermore, NTC thermistors have a short thermal response time; when the drug temperature changes, they can quickly sense the change and convert it into an electrical signal, transmitting it to the control module 24. This matches the rapid thermal response characteristics of the graphene heating film, enabling the control module 24 to promptly acquire temperature change information and issue control commands, reducing the lag in temperature adjustment and ensuring that the drug temperature returns to the optimal range within a short time, avoiding the impact of excessive temperature fluctuations on efficacy. The temperature sensor 222 can be an NTC high-precision thermistor, an infrared temperature sensor 222, or a platinum resistance sensor (such as PT100).

[0037] Preferably, in this embodiment, the main frame 1 is connected to both ends with Velcro straps 3. This arrangement allows the patient to securely fasten the device by adjusting the adhesive position of the Velcro according to the size and tightness requirements of their body part. Whether on the arm, leg, or waist, the Velcro straps 3 can tightly adhere the main frame 1 to the skin, preventing the device from shifting or falling off during use and ensuring that the traditional Chinese medicine in the drug placement slot 11 remains in effective contact with the affected area, thus guaranteeing the therapeutic effect. Furthermore, the Velcro straps 3 offer high flexibility in tightness adjustment, adapting to the needs of patients of different body types. Compared to straps with fixed sizes, the Velcro straps 3 can adjust the binding strength by changing the adhesive length, ensuring both secure fixation and avoiding excessive tightness that could affect blood circulation or cause discomfort, thus improving the versatility of the device and patient comfort. In addition, the opening and closing of the Velcro straps 3 is simple and quick, allowing patients to easily put on and take off the device without the need for other tools, making it particularly suitable for patients with limited mobility or those who need to operate the device independently. This convenience not only improves efficiency but also reduces inconvenience for patients, allowing them to focus more on treatment and indirectly ensuring that the drug achieves its best therapeutic effect in a stable environment.

[0038] Preferably, in this embodiment, the Velcro strap 3 has multiple ventilation holes 31, which are spaced apart. This arrangement of ventilation holes 31 enhances air circulation at the point of contact between the strap and the skin. Since the heating film 21 continuously heats up during use, the patient's local skin temperature may rise, leading to sweating. The spaced ventilation holes 31 accelerate heat dissipation and sweat evaporation, reducing discomfort caused by stuffiness in the area covered by the strap and preventing allergies or inflammation caused by prolonged exposure to a damp environment. This is especially suitable for scenarios involving prolonged medication application. Furthermore, the multiple spaced ventilation holes 31 allow for more even force distribution on the strap, preventing a decrease in Velcro adhesion due to localized stuffiness, ensuring the strap maintains a stable fixation effect, and indirectly guaranteeing continuous and effective contact between the medication and the affected area, allowing the medication to exert its therapeutic effect stably at the optimal temperature.

[0039] Preferably, in this embodiment, the Velcro strap 3 is connected to an abrasion-resistant plate 4, the abrasion resistance of which is greater than that of the Velcro strap 3. During long-term use, friction between the Velcro strap 3 and clothing, skin, or other objects causes gradual wear at the contact points, especially in areas with frequent opening and closing and concentrated stress, which are prone to problems such as fraying and breakage. The abrasion-resistant plate 4, with its higher abrasion resistance, can directly withstand the main friction and impact forces, reducing wear on the strap itself, effectively extending the overall lifespan of the strap, and reducing the frequency of device replacement. If the strap is partially damaged due to wear, it may lead to a decrease in fixing strength, or even device displacement. The abrasion-resistant plate 4 prevents the strap from wearing down and breaking under frequent use or stress, ensuring that the Velcro strap 3 always maintains reliable adhesion and binding ability, guaranteeing a tight fit between the main frame 1 and the patient's skin, and providing a stable fixing foundation for the drug to exert its therapeutic effect.

[0040] Preferably, in this embodiment, the abrasion-resistant piece 4 is sewn onto the Velcro strap 3. The sewing method allows the abrasion-resistant piece 4 and the Velcro strap 3 to form a tight and durable connection. Compared to methods such as adhesive, the sewing thread can evenly distribute the force at the contact points, effectively preventing the abrasion-resistant piece 4 from falling off due to stress when the strap is frequently opened and closed, pulled, or rubbed against other objects. This ensures that the abrasion-resistant piece 4 always provides protection and prevents the strap from wearing out quickly due to the loss of its protection. The sewing connection does not damage the original performance of the Velcro strap 3 and the abrasion-resistant piece 4; it does not affect the adhesion and breathability of the strap, nor does it reduce the abrasion resistance of the abrasion-resistant piece 4. Furthermore, the sewing thread material can be a durable material that matches the strap and the abrasion-resistant piece 4, ensuring that the connection remains stable after long-term use, indirectly guaranteeing the overall service life and safety of the device.

[0041] Preferably, in this embodiment, the heating device 2 further includes a temperature alarm device 5, which is used to issue an audible and visual alarm when the temperature is abnormal. The temperature alarm device 5 is electrically connected to the battery 23 and the control module 24. This configuration ensures that when the temperature in the drug placement tank 11 exceeds the safe range due to equipment malfunction (such as uncontrolled heating film 21 or malfunction of temperature detection component 22) or improper operation, the control module 24 will capture the abnormal temperature signal in real time and trigger the temperature alarm device 5. The audible and visual alarm provides both visual (e.g., flashing lights) and auditory (e.g., buzzer) alerts, quickly attracting the attention of patients or medical staff, preventing skin burns due to excessively high temperatures or delayed treatment due to excessively low temperatures, and providing timely safety warnings for users. Abnormal temperatures often mean that the drug has deviated from its optimal therapeutic temperature range; a persistent abnormal state may affect the drug's efficacy or even cause it to become ineffective. The timely response of the alarm device enables users to quickly troubleshoot problems (e.g., adjust device parameters, repair equipment), allowing the temperature to return to normal as soon as possible, reducing the adverse effects of abnormal temperatures on drug efficacy, and indirectly assisting the drug in maintaining a stable effect at a suitable temperature. In addition, the electrical connection design between the temperature alarm device 5, the control module 24, and the battery 23 ensures that it can work efficiently by relying on the device's power supply system and temperature monitoring system without the need for an additional independent power supply. This simplifies the device structure and ensures the synergy between the alarm function and the temperature control process, thereby improving the overall intelligence and reliability of the device.
