[0002] TCM external application therapy has been passed down for thousands of years and is still widely used in the medical community today. TCM external application is based on the principle of TCM meridians, with strong smelling drugs as the guide, to open knots and reach the lesions directly. It can penetrate the skin to produce blood circulation, remove blood stasis, promote menstruation, and dispel wind and cold. The specific practice of TCM external application therapy is to put Chinese herbal medicines with specific therapeutic effects into a sterilized clean gauze bag, and then apply it to the injured part of the human body that needs treatment, followed by heating (or not heating), through the long-term contact between the drug and the patient, the drug penetrates, promotes the expansion of local blood vessels in the injured area, and improves the blood circulation in the lesion. It is a clinical treatment method that achieves therapeutic effects through non-invasive external application. TCM external application therapy has the advantages of both drugs and hot compresses that traditional therapies do not have. Traditional Chinese medicine hot compress therapy is mainly suitable for some diseases without open injuries, such as joint sprains, dislocations, fractures, as well as cervical spondylosis, low back pain, rheumatoid arthritis, chronic gastroenteritis, irregular menstruation and other diseases, mainly for orthopedic diseases.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] The utility model provides a Chinese herbal medicine external compress belt that can be heated and kept warm. The PTC electric heater is an electric heater based on semiconductor materials, and its working principle is to use the characteristics of PTC (positive temperature coefficient) materials for heating. When the PTC electric heater is powered on, since the resistance of the PTC material increases with the increase of temperature, heat will be generated when the current passes through the PTC material, thereby causing the PTC material and the surrounding environment to heat up. When the temperature rises to a certain level, the resistance value of the PTC material increases sharply, thereby limiting the flow of current, reducing the heating power, reaching a self-stable state, and maintaining a constant temperature without the need for temperature control. The characteristics of the PTC heater: 1. Rapid heating, self-controllable temperature, and long service life. 2. Wide voltage range, both AC and DC power supplies. 3. When the PTC heats up, it does not turn red, has no open flames, does not burn, and is safe and reliable. Therefore, the utility model uses a rechargeable battery to provide power for the PTC heating plate 6, which is very suitable for heating the Chinese herbal medicine bag. The PTC heating plate 6 has the characteristics of automatic constant temperature, does not require a temperature control system, and can be directly powered on by the PTC.

[0016] like Figures 1 to 4 As shown, relevant data show that the heating temperature of the PTC heating plate 6 can be controlled by the working voltage of the rechargeable battery 9. When the working voltage increases by 2 times (or decreases by 1 / 2), the surface temperature of the PTC heating plate 6 rises (or decreases) by about 8°C. So it is easy to obtain experimental data. First, select the model of the PTC heating plate to ensure that its heating area is close to that of the Chinese herbal medicine bag. Secondly, select lithium batteries with different working voltages and use different working voltages to heat the PTC heating plate 6 for experiments. Because the weights of various Chinese herbal medicine bags are different, they are uncertain values, and the required heating energy is different. The power and voltage of the battery should be selected according to the heat absorption capacity of each herbal medicine bag. The experimental results make the temperature of the Chinese herbal medicine bag between 35-40°C. Thirdly, the depth inside the protective cover 7 should be greater than the height of the PTC heating plate 6, and the depth inside the battery box 10 should be greater than the height of the rechargeable battery 9. This design can protect the electrodes of the PTC heating plate 6 and the terminals of the rechargeable battery 9, which can effectively prevent power short circuit and ensure safety. Dongguan Tiancheng Thermistor Co., Ltd. (No. 6, Xinfeng Road, Dabeiwan, Changping Village, Daojiao Town, Dongguan City, Guangdong Province) has a PTC heating sheet product with a square shape, working voltage / 12-24V, normal temperature resistance / 100-300Ω, and surface temperature / ℃50-100℃. It is more suitable for this utility model. In actual use, a 6-12V battery is selected, and the temperature of the PTC heating sheet can be further reduced.

[0017] The method of using the utility model is as follows: Taking the treatment of the patient's leg joints as an example, first, the patient lies in bed, the doctor puts the Chinese herbal medicine package into the net bag 2, aligns the Chinese herbal medicine package with the patient's joints, and uses the nylon buckle 3 to wrap the bandage 1 around the patient's joints. Second, insert the internal filling insulation blocks 4 on both sides of the net bag 2, and adjust the tightness of the bandage 1. Third, turn on the power switch 10, measure the temperature of the Chinese herbal medicine package between 35-40°C, keep it warm for 30 minutes and then turn off the power switch 10. Fourth, remove the bandage 1, and the patient can walk. The battery box 11 of the utility model can also be set separately in other places, and the weight on the patient's leg 12 can be reduced by connecting the PTC heating plate 6 through the lengthened power cord 8.

[0018] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also make appropriate changes and modifications to the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
