Description

An infrared moxibustion device

technical field

The invention relates to a warming moxibustion device, in particular to a smokeless infrared warming moxibustion device which simulates traditional moxibustion therapy and can realize multi-acupoint moxibustion without body position restriction, and belongs to the technical field of medical care equipment.

Background technique

Moxibustion therapy has a history of thousands of years in my country, and it is an important part of traditional Chinese medicine acupuncture and moxibustion therapy. The ancients used moxibustion to prevent and treat diseases, so as to achieve the purpose of eliminating diseases, health care and prolonging life. For example, "Zhuangzi" records: the sage Confucius: "self-moxibustion without disease", refers to the use of moxibustion for health care;

Moxibustion has the effects of reconciling yin and yang, warming and dredging meridians, promoting qi and blood circulation, warming yang and tonifying deficiency, and invigorating the middle and replenishing qi. Modern medical research on moxibustion therapy shows that moxibustion mainly generates infrared rays of specific wavelengths through the burning of moxa sticks, radiating heat to stimulate acupoints, and at the same time relying on the pharmacological effects of volatile essential oils in moxa sticks to produce therapeutic effects. The heat burned by moxa sticks can promote blood circulation and metabolism through the penetration of acupuncture points, dredge the meridians, regulate the balance of yin and yang in the viscera, replenish yang energy and energy for the body, and eliminate evil qi.

When moxa sticks are burned, the radiation peak wavelength is 3.5 μm, which belongs to the mid-infrared region, which is quite different from the radiation peak of human acupoints with a wavelength of 7.5 μm. But when ginger, garlic and aconite cake are used for interval moxibustion, the spectral range changes The width is 5-13 μm, and the radiation peak is around 7.5 μm, which is almost consistent with the spectral range and radiation peak of human acupoints. The essential oil in moxa sticks contains a variety of chemical components, and the combustion products can penetrate the human body through the skin through moxibustion heat, playing a certain therapeutic effect.

In traditional moxibustion therapy, moxa sticks are ignited and then directed at the acupoints for direct warming, or ginger and garlic are used for indirect moxibustion at intervals. These methods have great restrictions on the patient's position, and often cannot treat multiple acupoints at the same time. According to the theory of TCM syndrome differentiation and treatment, moxibustion therapists usually prescribe "moxibustion prescriptions" consisting of several acupoints to treat multiple acupoints. However, due to the limitations of traditional moxibustion treatment methods, it is difficult to achieve multi-point treatment at the same time, thus affecting the curative effect and prolonging the treatment time. In addition, during the period from the burning of moxa sticks to the time when the spacer needs to be replaced when the patient feels burning pain, the actual warming time is very short, the exact warming temperature and time cannot be accurately guaranteed, and the treatment process does not meet the standardization requirements. It is also difficult to guarantee. In addition, the smoke produced during the burning of moxa sticks will have an adverse effect on the respiratory system of both patients and medical staff. Burning moxibustion strips falling on the hospital bed will not only burn the sheets, but also cause a fire. Moreover, because moxibustion requires continuous inspection and care, the number of patients under the care of a medical worker is greatly limited.

In order to overcome the shortcomings of traditional moxibustion therapy, many researchers have carried out reforms and innovations based on the mechanism of moxibustion therapy over the years, and developed a variety of infrared moxibustion devices, such as:

The invention patent "An Electric Heating Moxibustion Device" with application number 201110145263.8, the device is cylindrical, and the PCT heating element is used to heat the infrared radiator coated with 2-4μm and 14-16μm infrared materials on the surface, and the infrared radiation can be adjusted manually The distance between the device and the skin simulates traditional moxibustion therapy, but because the device has no precise temperature adjustment and constant temperature control function, it cannot meet the national "IEC60601 General Requirements for the Safety of Medical Electrical Equipment" that the maximum temperature of therapeutic medical devices should not exceed 61 ℃ requirements, and can only be used for moxibustion on one acupoint at a time.

Application No. 200910056991.4 "Laser Infrared Moxibustion Device Based on Traditional Moxibustion Infrared Spectrum" uses 2-4 μm and 9-11 μm lasers to directly irradiate acupoints for treatment, although the infrared moxibustion device simulates moxibustion moxibustion and partition moxibustion , but one instrument has only one laser source, and can only irradiate one acupuncture point at a time, and the patient's body position must be fixed, otherwise the body position will move away from the acupuncture point, and the therapeutic effect will not be achieved.

But unfortunately, because existing moxibustion devices have one or another problem, so that the traditional moxibustion therapy is still used clinically at present, thereby limiting the wide application of moxibustion therapy.

Fig. 3 shows the temperature control schematic diagram of the infrared moxibustion device provided in this embodiment. It can be seen from Fig. 3: when in use, first set the moxibustion temperature T ₁ in the thermostat 2, after turning on the infrared moxibustion device, the temperature sensor 12a sends the measured temperature _T2 signal of the ceramic heating sheet 13 to the single-chip microcomputer 21. After the single-chip microcomputer 21 compares _T1 and _T2 , the temperature difference signal is converted into an electric power output signal, which is amplified by the amplifier 22 and regulated by the control circuit 23. Power is supplied to the ceramic heating sheet 13 to generate heat, and the ceramic heating sheet 13 conducts heat to the infrared radiation sheet 14 after heating, and the infrared radiation sheet 14 generates infrared rays with a wavelength of 8 to 14 μm after being heated, and radiates on the fixed acupuncture points for moxibustion; At this time, the temperature sensor 12a sends the measured temperature T ₂ signal of the ceramic heating sheet 13 to the single-chip microcomputer 21 at any time, and the single-chip microcomputer 21 constantly compares T ₁ and T ₂ to adjust the electric power output signal, and the amplifier 22 and the control circuit 23 adjust the ceramic heating. The electric power output of the sheet 13 adjusts the calorific value, controls its temperature, and then adjusts the temperature of the infrared radiation sheet 14 and the radiation of infrared rays, and so on, so as to achieve the purpose of precisely controlling the moxibustion temperature. At the same time, another temperature sensor 12b also sends the ceramic heating sheet 13 to the single-chip microcomputer 21 in real time to ensure that the ceramic heating sheet 13 temperature T ₂ signal works uninterruptedly when the temperature sensor 12a is damaged. At the same time, when the ceramic heating sheet 13 temperature T ₂ When the temperature reaches 60°C, the temperature signal can be transmitted to the thermostat 2, and the single-chip microcomputer 21 of the thermostat 2 cuts off the power supply of the ceramic heating sheet 13 to stop heating and send out an alarm sound to inform the user to stop using it for maintenance, ensuring The infrared moxibustion device of the present invention complies with "IEC60601 General Safety Requirements for Medical Electrical Equipment".

Described thermostat 2 comprises power adapter, power switch, touch display screen, single-chip microcomputer, control circuit and protection circuit, wire and a plurality of output ports, is provided with switch button, temperature setting, time setting, output port button , preferably with countdown, real-time temperature display and alarm functions, so as to realize the automatic stop of heating when the moxibustion time is up; the touch screen can complete and display the setting of parameters such as temperature and moxibustion time, and also display each The use status and fault conditions of the output port of the road channel; the relay in the control circuit can be a solid-state relay, and a semiconductor device can be used instead of the traditional electric contact as a switching device; The port voltage is 2V, the current is 0.26A, and the power is 0.52W, which ensures that touching the moxibustion sheet directly with the hand will not cause burns when the power is on, and the temperature difference between the moxibustion sheets is less than 1°C, effectively ensuring patient safety and moxibustion effect.

The temperature sensor can be selected thermistor; each moxibustion sheet is preferably provided with 2 temperature sensors, one of which senses the temperature of the ceramic heating sheet, and passes the measured temperature to the thermostat 2, and the thermostat 2 Control the temperature of the ceramic heating element and maintain a constant temperature to achieve the purpose of precisely controlling the temperature of the moxibustion treatment element; the other sensor is mainly used for safety protection. When the previous sensor fails or the temperature of the ceramic heating element exceeds 60°C, the temperature signal can be transmitted to the The thermostat 2 cuts off the power supply of the ceramic heating sheet by the thermostat 2 to stop heating and send out an alarm sound to inform the user to stop using for maintenance.

The thermostat 2 is preferably a multi-channel temperature controller, having at least 2 channels; the input terminal of each channel is electrically connected to the temperature sensor of a moxibustion treatment sheet, and the output terminal of each channel is connected to a moxibustion treatment sheet. The ceramic heating sheet of the sheet is electrically connected to realize the temperature control of multiple moxibustion sheets at the same time and meet the requirements of multi-point moxibustion. When in use, it can be fixed on the acupuncture points of the human body by common fixing devices such as adhesive sheets, fixing belts, and velcro. According to the patient's condition, wormwood essential oil or some kind of drug patch can be placed between the infrared radiation sheet and the skin acupuncture points during treatment, and then fixed on the acupuncture points. When heated, the moxibustion tablet can not only radiate the corresponding infrared rays, but also penetrate the wormwood essential oil or other medicines into the subcutaneous, simulating the treatment principle of traditional moxibustion therapy for treatment.

Described protective cover 11 and protective cover 15 can adopt ABS plastics to make, and protective cover can be made oblate or other suitable shapes, and if oblate, can establish the different specifications of diameter from 5mm to 50mm.

The ceramic heating sheet is made of alumina, with a thickness of 1-2mm. One end of the lead wire is connected to a temperature controller, and the temperature is controlled by the temperature controller and kept constant, so that the temperature of the ceramic heating sheet can be between 35-55°C. Can be adjusted arbitrarily.

The infrared radiation sheet is made of yttrium oxide pressed and sintered, attached to one side of the ceramic heating sheet, and heated by conduction of the ceramic heating sheet, and can radiate infrared rays with a wavelength of 8-14 μm after heating, thereby producing clinical therapeutic effects. According to the different needs of treatment or in order to prevent the cross-infection of bacteria and viruses between patients, the infrared radiation film can be designed to be used once, and different specifications can be replaced according to the needs of each treatment.

It can be seen from Figure 4 that when the ceramic heating sheet 13 is heated to 32.8°C, the temperature of the infrared radiation sheet 14 is 1 higher than that of the ceramic heating sheet After that, as the temperature rises, the temperature difference between the infrared radiation sheet 14 and the ceramic heating sheet 13 becomes larger and larger. When the temperature of the ceramic heating sheet reaches 43.5°C, the temperature of the infrared radiation sheet 14 reaches 45.9°C, a difference of 2.4°C. This shows that The temperature of the ceramic heating element is controlled by the voltage controlled by the thermostat 2. As the voltage rises, the temperature of the ceramic heating element also rises. At the same time, the heat transmitted to the infrared radiation element is also high, and the temperature of the infrared radiation element also rises accordingly. The higher the radiated far-infrared energy, the higher the radiated far-infrared energy. After reaching a certain temperature, the infrared radiation sheet is heated to generate far-infrared radiation, and the temperature will exceed the temperature of the ceramic heating sheet.

Fig. 5 shows the radiation spectrum diagram of the infrared radiation sheet provided in this embodiment at 60°C. It can be seen from Figure 5 that at 60°C, the far-infrared spectrum emitted by the infrared radiation sheet 14 made of yttrium oxide pressed and sintered is 8-14 μm, with a peak at 9-12 μm, which is close to the spectrum of the Hegu acupoint of the human body, and its curative effect is similar to that of traditional moxa sticks. Moxibustion is similar.

The operation of using the infrared moxibustion device of the present invention for moxibustion is as follows:

a) Turn on the power and set the moxibustion parameters on the thermostat 2, including: moxibustion temperature, moxibustion time, number of output ports;

b) Use a fixing device to fix the moxibustion sheet on the acupoints of the patient requiring moxibustion, or first apply mugwort essential oil or place spacer medicine on the acupoints, and then use a fixing device to fix the moxibustion sheet on it;

c) Under the control of the temperature controller 2, the ceramic heating sheet of the moxibustion sheet generates heat and conducts the heat to the infrared radiation sheet to generate 8-14 μm infrared rays, which radiate on the fixed acupuncture points. The temperature is transmitted to the thermostat 2, and the temperature is controlled by the thermostat 2;

d) When the moxibustion treatment reaches the set end time, the thermostat 2 cuts off the heating power supply, the moxibustion treatment sheet no longer heats up, the moxibustion treatment ends, the user turns off the power supply, takes off the moxibustion treatment treatment piece, and completes a course of moxibustion treatment.

Effect test:

1) Comparison of moxibustion effects

10 volunteers conducted a comparative test of traditional moxibustion moxibustion and the infrared moxibustion device of the present invention on Neiguan and Hegu acupoints. After moxibustion, the skin temperature of volunteers' acupoints was higher than their original temperature before moxibustion, and the difference was extremely significant. The temperature of the acupoint center after moxibustion by the infrared warm moxibustion device of the present invention is slightly higher than that after traditional moxibustion, but there is no statistically significant difference. Most of the volunteers felt that after 5 minutes of moxibustion with the infrared warm moxibustion device of the present invention, the thermal sensation radiated toward the forearm, indicating that the moxibustion effect was obvious.

Table 1 shows the comparative test results of traditional moxa stick moxibustion therapy and infrared warm moxibustion device moxibustion therapy of the present invention at Neiguan and Hegu acupoints of volunteers. It can be seen from the comparative test results that:

After moxibustion with the infrared warming moxibustion device of the present invention and traditional moxa stick moxibustion therapy, the temperature rise of the acupoints is basically the same, so it can be inferred that the curative effect is also basically the same.

Table 1.

Note: The data was processed by SPSS18 software, compared with the temperature of the ipsilateral acupoint before moxibustion, *P≤0.01, **P≤0.05.

2) Security testing

During the volunteer test, the highest temperature of the moxibustion sheet reached 49.5°C. After the moxibustion sheet was removed, only erythema in the shape of the moxibustion sheet remained on the skin, which disappeared after a few hours without blistering or swelling. When the measured temperature of the moxibustion treatment sheet exceeds 60°C, the infrared moxibustion device of the present invention can automatically cut off the power supply and send out an alarm to ensure the safety of the patient. Therefore, it can be considered that the moxibustion process of the infrared moxibustion device of the present invention is safe. The moxibustion device itself is also safe.

3) Effectiveness test

When the infrared moxibustion device of the present invention is energized, the ceramic heating sheet heats up and transmits to the lower infrared radiation sheet. When the ceramic heating sheet is heated to 32.8°C, the temperature of the infrared radiation sheet will be 1°C higher than that of the ceramic heating sheet. As the temperature rises, the temperature difference between the infrared radiation sheet and the ceramic heating sheet becomes larger and larger. When the temperature of the ceramic heating sheet reaches 43.5°C, the temperature of the infrared radiation sheet reaches 45.9°C, which is 2.4°C higher, indicating that the infrared radiation sheet is excited by heat to radiate far-infrared rays. . Measured by an infrared spectrometer, the infrared spectrum emitted by the infrared radiation sheet at 60°C is 8-14 μm, and the peak is at 9-12 μm, which is close to the spectrum of the acupoints of the human body. Similar far-infrared radiation when burned, with similar therapeutic effects.
