The circuit diagram of the electronic rhinitis treatment instrument is shown in the following figure: This circuit is electric pulse acupuncture, which can be combined with medication to treat rhinitis. The power supply in the electrotherapy device charges C1 through R1 and R2. When the voltage on the capacitor rises to the upper limit threshold level of the circuit 2 / 3Vcc, the voltage comparator A in the timer circuit outputs a high level, thereby making the output Vo of the circuit low, and the discharge tube inside the circuit Turn on, make the capacitor C1 discharge through the discharge tube through the resistor R2; when the voltage drops to 1 / 3Vcc, the output of the timer becomes high level, and the discharge tube is disconnected. The circuit repeats the above process, causing oscillation. The output pulse voltage of the time-base circuit is boosted by the transformer T, and a rectangular pulse of 80Vp is output, which acts on the acupuncture points of the human body and can produce acupuncture-like effects such as acupuncture, swelling, and numbness. Potentiometer RP can adjust the output to meet the needs of patients' acupoints.
