[0002] The internal heat needle therapy device inserts acupuncture needles into specific acupuncture points of the human body, heats the acupuncture needles and conducts infrared heat energy into the human body, thereby playing a therapeutic role in dredging meridians, promoting blood circulation, and relieving pain.
[0003] At present, most of the acupuncture needles used in clinical practice are stainless steel needles. Stainless steel needles have good toughness and strength, and the needle body is lubricated and can withstand high temperatures. It is not easily corroded by chemicals, and it is inexpensive. Therefore, modern acupuncture needles are basically made of stainless steel. After the internal heat needle therapy instrument is connected to the acupuncture needle, due to the low thermal conductivity of stainless steel, when the acupuncture needle is heated at the rated temperature, it is difficult to judge the temperature of the needle at different lengths of time. At the same time, during acupuncture, the needle has already penetrated into the human skin tissue, and the temperature of the needle cannot be directly measured using external tools, making it difficult to control the temperature of the needle.

[0005] To achieve the above object, the utility model provides the following technical solution: a needle temperature measuring device for an internal heat needle therapeutic instrument, comprising an insulating shell and a needle, and also comprising:
[0006] A heating structure, which is arranged on the inner wall of the insulating shell and is used to heat the needle;

[0008] The heating assembly includes a heating plate, which is mounted on the inner wall of the insulating shell, and the top of the insulating shell is connected to a wire, which is externally connected to the internal heat needle therapy instrument;
[0009] Among them, the temperature measurement component includes an insulation layer, which is embedded in the middle of the needle, and a heat-conducting wire is embedded in the middle of the insulation layer. An insulation layer is installed on the inner wall of the heating plate, and a temperature sensor is installed on the inner wall of the insulation layer. The outside of the temperature sensor is connected to a sensor lead.

Based on the embodiments in 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.
[0021] like Figures 1 to 3 As shown, the utility model provides a needle temperature measuring device for an internal heating needle therapeutic instrument, comprising an insulating shell 1 and a needle 3, and also comprising:
[0022] A heating structure, which is arranged on the inner wall of the insulating shell 1 and is used to heat the needle 3;
[0023] A temperature measuring component, which is arranged on the insulating shell 1 and the needle 3 and is used to measure the temperature of the needle 3;
[0024] The heating assembly includes a heating plate 6, which is mounted on the inner wall of the insulating shell 1. The top of the insulating shell 1 is connected to a wire 2, which is externally connected to the internal heat needle therapy device.
[0025] Among them, the temperature measuring component includes an insulation layer 4, the insulation layer 4 is embedded in the middle of the needle 3, the middle of the insulation layer 4 is embedded with a heat-conducting wire 5, the inner wall of the heating plate 6 is installed with an insulation layer 7, the inner wall of the insulation layer 7 is installed with a temperature sensor 8, and the outside of the temperature sensor 8 is connected with a sensor lead 9.
[0026] Through the cooperation between the heating plate 6 and the needle 3, heat can be transferred to the needle 3. At the same time, the heat insulation layer 4 will prevent the heat from being directly transferred to the outer surface of the thermal wire 5. When the heat is transferred to the position of the needle 3, the end of the thermal wire 5 will absorb the heat until the heat is transferred to the sensor lead 9, and then the temperature of the needle can be measured by the temperature sensor 8.
[0027] The insulating layer 7 is made of polyimide, and the heating plate 6 is sleeved with the needle 3 .
[0028] The insulating layer 7 can play an insulating role, and through the cooperation between the heating plate 6 and the needle 3, the heat will be conducted to the inside of the needle 3 through the heating plate 6.
[0029] The end of the sensor lead 9 is in contact with the heat-conducting wire 5 , and the heat-insulating layer 4 is made of glass fiber.
[0030] The design of the heat insulating layer 4 can prevent the heat from being directly transferred to the inside of the thermal wire 5 when the heating plate 6 heats the needle 3, thereby avoiding affecting the detection effect of the temperature sensor 8. The heat can only be detected by the thermal wire 5 when it is transferred to the needle tip of the needle 3.
[0031] A spring sheet 10 is installed at the bottom of the heating sheet 6 , and the spring sheet 10 is in compression contact with the needle 3 .
[0032] Through the elastic force of the spring sheet 10, when the heating sheet 6 and the needle 3 are sleeved, the spring sheet 10 will press the outer surface of the needle 3, so that the heating sheet 6 and the needle 3 are more stable when sleeved.
[0033] The heat conducting wire 5 is made of copper wire, and the end of the heat conducting wire 5 extends to the needle tip of the needle 3 .
[0034] The design of the heat-conducting wire 5 has good thermal conductivity. At the same time, since the end of the heat-conducting wire 5 extends to the needle tip of the needle 3, it can sense the heat at the needle tip 3.
[0035] The working principle and use process of this utility model:
[0036] First, after the needle 3 is inserted into the human body, the needle 3 can be heated through the cooperation between the heating plate 6 and the needle 3. At the same time, the heat insulation layer 4 will prevent the heat from being directly transferred to the outer surface of the thermal wire 5. When the heat is transferred to the position of the needle 3, the heat can be transferred from the end of the thermal wire 5 until the heat is transferred to the sensor lead 9, and then the temperature of the needle can be measured by the temperature sensor 8.
