Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an intelligent temperature-controlled traditional Chinese medicine fumigation device. Background Technology

[0002] Traditional Chinese medicine fumigation is a common external treatment method in TCM. By heating, the active ingredients in the herbal patches volatilize and act on the skin surface to achieve therapeutic purposes such as warming the meridians, dispelling cold and dampness, etc. Traditional Chinese medicine moxibustion and medicated moxibustion mostly rely on open flame heating, and the temperature depends entirely on the operator's experience. This is not only inconvenient to operate and produces a lot of smoke, but also very easy to cause skin burns due to excessive temperature.

[0003] To address these issues, existing technologies include electrically heated herbal fumigation or hot compress devices that heat herbal patches using electric heating elements. However, these devices still have the following drawbacks: First, the temperature sensor is typically located at the heating element, detecting the temperature of the heating element itself rather than the skin temperature. Because heat loss and fluctuation occur as it travels through the herbal patch and air layer to the skin, the heating element temperature does not accurately reflect the actual heating of the skin, still posing a risk of low-temperature burns or insufficient temperature and poor fumigation effect. Second, gaps can easily form between the herbal patch and the heating surface due to assembly errors or differences in patch thickness, leading to uneven heating and unstable drug volatilization. Third, existing devices cannot identify whether the herbal patch is installed or properly positioned; overheating and charring may occur during unloaded or tilted heating. Fourth, the volatile gases generated during fumigation easily leak from the gaps between the device and the skin, resulting in low utilization.

[0004] Therefore, how to provide a traditional Chinese medicine patch fumigation device that can directly detect and stably control skin temperature, ensure uniform heating of the patch, and has self-checking capability for installation status has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the above problems, the present invention provides the following technical solution:

[0006] A smart temperature-controlled traditional Chinese medicine patch fumigation device includes a main shell, which is a hollow container. Multiple through fumigation windows are provided on the bottom surface of the main shell for releasing fumigation gas.

[0007] A first temperature sensor is provided in the non-fumigation window area on the bottom surface of the main housing. The first temperature sensor is a thin-film temperature sensor used to collect skin temperature.

[0008] Inside the main housing, a herbal medicine compartment is located above the fumigation window to hold replaceable herbal patches; a heating device is located above the herbal medicine compartment, which heats the herbal patches inside the compartment by heating the top of the compartment; a microcontroller is also located inside the main housing, which controls the heating device to maintain the skin temperature within a preset temperature range based on the skin temperature collected by the first temperature sensor.

[0009] Preferably, a support net and an elastic element are provided between the herbal patch and the fumigation window inside the herbal medicine storage box; the elastic element is connected to the support net and is used to provide an upward preload to the support net, so that the support net continuously applies an upward supporting force to the herbal patch.

[0010] Preferably, a second temperature sensor is provided between the herbal medicine storage box and the heating device to detect the temperature of the herbal medicine patch; while the microcontroller maintains the skin temperature within the preset temperature range, it prioritizes ensuring that the temperature of the herbal medicine patch does not exceed the over-temperature threshold.

[0011] Preferably, when the device starts working, the microcontroller controls the heating device to heat in a preset manner. When the heating rate of the herbal patch exceeds the temperature rise rate threshold, the device stops working and issues an alarm.

[0012] Preferably, the second temperature sensor is a multi-point temperature sensor. When the microcontroller starts working, it controls the heating device to heat in a preset manner. When the multi-point temperature deviation detected by the second temperature sensor exceeds the temperature difference threshold, it issues an alarm for misaligned installation of the herbal patch.

[0013] Preferably, a sealing ring is provided on the outer periphery of the bottom surface of the main housing.

[0014] Preferably, the first temperature sensor is a thin-film NTC thermistor or a thin-film platinum resistance thermometer.

[0015] Preferably, the preset temperature range is 42±1℃.

[0016] Preferably, the heating device includes a heating wire and a heat spreader plate.

[0017] Preferably, the heating device is a graphene heating film.

[0018] Beneficial effects:

[0019] (1) The first temperature sensor adopts a thin film temperature sensor and is set in the non-fumigation window area on the bottom surface of the main housing. When working, it is in direct contact with the skin and directly collects the skin temperature of the treatment area. The microcontroller controls the heating device in a closed loop according to this, so that the skin temperature is kept stable within the preset temperature range (preferably 42±1℃). This avoids low-temperature burns and ensures the stability and consistency of the fumigation therapy effect.

[0020] (2) A support net and an elastic element are provided between the Chinese medicine patch and the fumigation window. The elastic element continuously applies an upward support force to the Chinese medicine patch through the support net, so that the Chinese medicine patch is always in close contact with the heating surface at the top of the Chinese medicine box, the heating is uniform, the efficacy is stable, and it can be adapted to Chinese medicine patches of different thicknesses.

[0021] (3) A second temperature sensor is provided between the Chinese medicine storage box and the heating device. During the temperature control process, the microcontroller prioritizes ensuring that the temperature of the Chinese medicine patch does not exceed the over-temperature threshold to prevent the Chinese medicine patch from overheating and charring, thereby improving safety.

[0022] (4) The abnormal state of not installing Chinese medicine patch can be automatically identified by detecting the heating rate during the start-up stage and the machine will be stopped and alarmed; when the second temperature sensor is a multi-point temperature sensor, the installation deviation of the Chinese medicine patch can also be identified by the multi-point temperature deviation to avoid uneven heating and realize self-check of installation status.

[0023] (5) A sealing ring is provided on the outer periphery of the bottom surface of the main shell. When the device is in contact with the skin, it can seal the fumigation gas in the treatment area, reduce the leakage of volatile gas, improve the utilization rate of the effective ingredients of traditional Chinese medicine and stabilize the local thermal environment.

[0029] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] like Figures 1 to 4As shown, an intelligent temperature-controlled herbal patch fumigation device includes a main shell 1, which is a hollow container. Multiple through-hole fumigation windows are provided on the bottom surface of the main shell 1 for releasing fumigation gases. In a further embodiment, a sealing ring 3 is provided around the bottom surface of the main shell 1. When the bottom surface of the herbal patch fumigation device is in close contact with the skin, the fumigation gases can be sealed off, reducing leakage, improving the utilization rate of the volatile gases from the herbal medicine, and stabilizing the internal thermal environment.

[0031] A first temperature sensor 2 is provided in the non-fumigation window area on the bottom surface of the main housing 1. The first temperature sensor 2 is a thin-film temperature sensor used to collect skin temperature. In some possible embodiments, the first temperature sensor 2 is a thin-film NTC thermistor or a thin-film platinum resistance thermometer. In operation, the first temperature sensor 2 is in direct contact with the skin and can directly obtain the temperature of the skin in the treatment area.

[0032] Inside the main housing 1, a herbal medicine container 4 is located above the fumigation window to hold replaceable herbal patches 6. A heating device 5 is located above the herbal medicine container 4, which heats the top of the container and thus the herbal patches 6 inside. A microcontroller is also located inside the main housing 1. Based on the skin temperature collected by the first temperature sensor 2, the microcontroller controls the heating device 5 to maintain the skin temperature within a preset temperature range. As a preferred embodiment, the preset temperature range is 42±1℃. Prolonged contact of human skin with a heat source above 44℃ poses a risk of low-temperature burns, while fumigation is ineffective below 40℃. Therefore, a preset temperature range of 42±1℃ is preferred. Specific control methods can use algorithms such as PID, which are common knowledge in the field and will not be elaborated here.

[0033] In some embodiments, the heating device 5 includes a heating wire and a heat spreader plate, and the heat generated by the heating wire is homogenized by the heat spreader plate and conducted to the top of the Chinese medicine storage box 4; in other embodiments, the heating device 5 is a graphene heating film, which uses its uniform surface heating characteristics to directly serve as a heat spreader heating surface.

[0034] As a further embodiment, a support net 7 and an elastic element 8 are provided between the herbal patch 6 and the fumigation window inside the herbal medicine storage box 4. The elastic element 8 is connected to the support net 7 and provides an upward preload to the support net 7, so that the support net 7 continuously applies an upward supporting force to the herbal patch 6, ensuring that the herbal patch 6 remains in close contact with the top of the herbal medicine storage box 4 for better heating. In this embodiment, the elastic element 8 is a spring.

[0035] As a further implementation, a second temperature sensor (not shown in the figure) is provided between the herbal medicine storage box 4 and the heating device 5 to detect the temperature of the herbal medicine patch 6. While maintaining the skin temperature within a preset temperature range, the microcontroller prioritizes ensuring that the temperature of the herbal medicine patch 6 does not exceed the overheating threshold to prevent overheating and charring. At startup, the microcontroller controls the heating device 5 to heat in a preset manner (e.g., heating at rated power for 10 seconds). When the heating rate of the herbal medicine patch 6 exceeds the temperature rise rate threshold, it stops working and issues an alarm indicating that no herbal medicine patch 6 is installed. When there is a herbal medicine patch 6 in the herbal medicine storage box 4, the herbal medicine patch 6 acts as a heat capacity load, absorbing heat, resulting in a slower temperature rise at the heating interface. When there is no herbal medicine patch 6, the heat capacity is small, and the temperature rise rate is significantly higher. By comparing the measured temperature rise rate with the temperature rise rate threshold, it can be determined that there is no herbal patch 6 at this time, and then the operation stops and an alarm for not installing the herbal patch 6 is issued. In a preferred embodiment, the second temperature sensor is a multi-point temperature sensor. When the operation starts, the microcontroller controls the heating device 5 to heat in a preset manner (e.g., heating for 10 seconds at rated power). When the multi-point temperature deviation detected by the second temperature sensor exceeds the temperature difference threshold, an alarm for misaligned installation of the herbal patch 6 is issued. During the installation of the herbal patch 6, if it is not installed in place, or if the support net 7 becomes stuck or misaligned, so that the herbal patch 6 does not fit tightly against the upper part of the herbal medicine box 4, the multi-point temperature detected by the second temperature sensor will show a large deviation. At this time, the operation can be stopped and the user should be notified.

[0036] It should be noted that replacing the corresponding structure of the Chinese medicine patch 6 inside the Chinese medicine storage box 4 is common knowledge in the field and is not limited here. In one possible implementation, the top of the main shell 1 and the Chinese medicine storage box 4 are detachable to realize the replacement of the Chinese medicine patch 6.

[0037] The fumigation device can be fixed to the skin in various ways during operation, such as with elastic bandages or by setting medical pressure-sensitive tape at the bottom of the main housing 1. The present invention does not limit the way the fumigation device is fixed to the skin and can be selected as needed.

[0038] During use, the bottom of the herbal patch fumigation device is attached to the skin, and the microcontroller controls the heating device 5 to heat the herbal patch 6. The volatile substances generated by the heating of the herbal patch 6 continuously fumigate the skin through the fumigation window. During this process, the microcontroller controls the skin temperature of the treatment area to be maintained within the preset temperature range.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
