Self-adaptive control skin surface electrical stimulation device and method

Abstract

The invention discloses a self-adaptive control skin surface electrical stimulation device, which uses a stimulation electrode to act on skin surfaces. The device is characterized by comprising a voltage regulating circuit, an electric pulse generation circuit, a stimulation electrode, a current measuring circuit and a skin resistance calculating unit, wherein a human body is stimulated by manually regulating the initial voltage value of the stimulation circuit; the current measuring circuit detects a current input into the human body; the current voltage and current are used to calculate the resistance of the skin; the voltage is regulated according to the relationship between feeling and a stimulation strength, so that the feeling of a person can keep constant. Compared with the prior art, the system has the advantages that: as a body surface electrical stimulation mode is adopted, when the device is used, an electrical stimulation electrode is contacted with the body surface, namely the needle electrode does not penetrate the human body, so the person has no pains and the use is convenient; and the current measuring circuit reduces noises and acquires effective current values correctly, so high-accuracy self-adaptive control of electrical stimulation can be realized under a complex actual application condition.

Description

technical field [0001] The invention relates to the field of rehabilitation medical engineering, in particular to a device and method for human body rehabilitation treatment using electrical stimulation signals. Background technique [0002] By releasing electrical pulses with different characteristics to target areas on the surface of the human skin or deep tissues, people can obtain different stimulation sensations, relieve pain, and replace traditional acupuncture to treat diseases. In order to allow users to feel a relatively constant stimulation intensity, it is necessary to develop a device that can sense skin characteristics and output appropriate stimulation signals, so as to facilitate the use of body surface electrical stimulation in daily life. [0003] There are two main methods of electrical stimulation: transcutaneous electrical stimulation and surface electrical stimulation. Transcutaneous electrical stimulation refers to piercing needle-like electrodes throu...
