Abstract: The present invention relates to a blood pressure depressor for depressing the hypertension in the human body. The device consists mainly of integrated circuits and several resisters, capacitors, light emitting diodes, ear electrodes, hand electrode, pocket and piezoelectric ceramic buzzer. Through a metal electrode contacted with a specific sensitive point of the human body a bioelectric current flows to a charge-discharge circuit which is connected with a electronic analogue switch circuit, an oscillating/frequency dividing circuit and an adjustable timing automatic alarm circuit to thereby attain the hypotensive and curative effect. It has a simple configuration and a convenient usage, and the blood pressure of a patient may be depressed by 10-40 mmHg through the use of it for 10 minutes. The cure rate reaches above 95% which shows a prominent curative effect, so that the device becomes a good doctor of the hypertension patients. It has no influence to the blood pressure of a normal person.
