Description

Technical Field

[0001] The utility model relates to the technical field of internal heating acupuncture therapeutic instruments, in particular to a novel internal heating acupuncture therapeutic instrument. Background Art

[0002] Electrothermal acupuncture therapy is a method of stimulating specific acupuncture points with specially made electrothermal acupuncture. After the needle is inserted into the human body, an adjustable voltage-stabilized power supply is used to pass current through the needle to generate heat, thereby achieving the purpose of treatment. It has the combined effects of traditional warm needles and fire needles. Traditional warm needle therapy is to add a moxa stick to the tail of the needle, ignite it and transmit its heat through the needle to the body. Traditional fire needle therapy is to heat the needle first and then quickly insert the needle into the human body while it is hot, so that the temperature of the human tissue around the needle increases. However, the temperature is not easy to control during these two treatments, and the needle is easy to burn the skin. In the past, the temperature control of internal heat acupuncture therapeutic instruments mainly relied on transformers, which were bulky and not very accurate.

The circuit connection method of the switching power supply board is: a power switch and an external power supply interface are arranged on the rear panel of the chassis, and the external power supply interface is electrically connected to the AC input port of the switching power supply board after passing through the power switch; The main control board is used to control and adjust the heating temperature and heating time of the real-time internal heating needle interface of the output board. The main control board controls the pulse and pulse time given to the output board. The circuit connection method of the main control board is: through the 12V DC output port of the switch power board, the P5 interface of the main control board is connected to it for power supply, the P15 interface of the main control board is electrically connected to the display, the P14 interface of the main control board is electrically connected to the P11 signal input interface of the output board, and the P11 interface of the main control board is electrically connected to the P10 signal output interface of the output board; The output board is used to heat the internal heating needle through the internal heating needle interface. The output board adjusts the output pulses at both ends of the transformer according to the pulse signal transmitted by the main control board to control the heating temperature and heating time. The circuit connection method of the output board is as follows: the chassis contains two output boards, and the P11 interface and P10 interface of the first output board receive and send the pulse signal of the main control board respectively; the P11 interface and P10 interface of the second output board receive P12 and P17 of the first output board; the P14 power input port of the two output boards is connected to the 12V DC output port of the switch power board; the P1-P8 interfaces of the two output boards, each interface supplies power to two internal heating needles; every two adjacent interfaces of P1-P8 are connected to an internal heating needle wire jack.
