Description

Technical Field

[0001] The present invention relates to the field of electronic technology, and in particular to an electric temperature clamp heating circuit and an electrotherapy acupuncture device. Background Art

[0002] Electric warm needle is an upgraded and optimized form of traditional acupuncture. Electric warm needle can apply electrical stimulation of different frequencies and amplitudes to patients through the needle body, giving traditional acupuncture a new way of physical therapy and electrotherapy effect. Compared with traditional acupuncture moxibustion / warm moxibustion therapy, electric warm needle not only does not have the smell of moxa and the burns caused by unburned moxa powder, but also the treatment time and temperature can be precisely controlled, giving the human body a warm stimulation, which has the functions of warming the meridians and collaterals, promoting qi and blood circulation, removing dampness and cold, reducing swelling and dispersing knots, restoring yang and rescuing adverse conditions, as well as preventing diseases and health care.

[0003] The existing implementation methods of electric temperature needle are as follows: Figure 1 As shown in the figure, the treatment needle is a disposable consumable. After the doctor inserts the needle into the patient's body, an electric heating clip is clamped on the needle to heat it. Each needle is clamped with an electric heating clip. The electric heating clip is generally composed of Figure 1 The 7 components shown in the figure plus the pin and spring as the connector, have 3 wires inside connected to the external host circuit, two of which (heating +, heating -) serve as DC signal loops for electric temperature needle heating; the other one (electrotherapy output electrode) is the communication line of the electrotherapy waveform, which is paired with another "electrotherapy output electrode" on the corresponding electric temperature clip to form a loop through the patient's body resistance between the two needles.

[0004] The existing structure of the electric temperature needle implementation method has a relatively complex electric temperature clip structure and is not light in weight. When the electric temperature needle is inserted into the patient's body and then clamped on the needle body, the heavy electric temperature clip can easily cause the needle body to shake or fall off, causing pain to the patient. In addition, the heating circuit of the electric temperature clip of the existing structure is generally a low-voltage current, and the electrotherapy waveform is generally an AC pulse with a peak value of more than 100V. The two circuits need to be isolated from each other, otherwise they will interfere with each other and damage the device. Therefore, a thermally conductive insulating sheet needs to be configured in the electric temperature clip for isolation to prevent the two circuits from interfering with each other and damaging the device. However, the thermally conductive insulating sheet is easy to fall off during use, causing a short circuit in the circuit to damage the equipment, and the safety is relatively low.
