In-ear-type non-invasive ear vagus nerve stimulator and pulse output method thereof

Abstract

The invention discloses an in-ear-type non-invasive ear vagus nerve stimulator and a pulse output method thereof. The stimulator comprises left and right two in-ear-type electrodes and a control device; both the left and the right in-ear-type electrodes comprise two electrodes, namely an auricular concha area bent electrode and an external auditory canal electrode, so that the stimulation electricfield current energy returns to the control device along respective loops; the in-ear-type electrodes also comprise a sound transmission hole penetrating the electrodes; electric-conduction retainingholes are arranged on the auricular concha area bent electrode and an external auditory canal electrode, and the electric-conduction retaining holes can protect a electric-conduction solvent from being volatilized; and the control device is internally provided with output waveform data corresponding to a plurality of treatment modes, and outputs different waveform data according to different treatment modes.

Description

technical field [0001] The invention relates to the field of using current pulse energy to stimulate nerves or tissues to treat related diseases, in particular to an in-ear non-invasive ear vagus nerve stimulator. The device and method of the present invention can be used to stimulate the ear branch of the vagus nerve in patients to treat various diseases, such as: headache, depression, anxiety, epilepsy, obesity, diabetes, Alzheimer's disease and the like. Background technique [0002] Electrical stimulation has been used to treat diseases for more than 2,000 years, but it was the first clinical application of a cardiac pacemaker in the 1950s that was actually used for clinical treatment. Modern electrophysiological studies have shown that electrical stimulation of nerves will directly or indirectly depolarize the nerve membrane, causing the discharge of action potentials, or hyperpolarize the nerve membrane to prevent the release of action potentials. This nerve electrica...

AI Technical Summary

Problems solved by technology

Metal electrode + conductive gel needs to be cleaned every time the electrode is used, and if the conductive gel is not covered well, it will cause direct contact between the metal electrode and the skin, which will easily cause electric burns

The conductive silicone + conductive liquid method is prone to tingling due to the increase in the impedance between the conductive silicone and the skin due to the volatilization of the conductive liquid

CN105056394A discloses a kind of host and electrode integrated ear vagus nerve stimulator, although it improves the portability and comfort of wearing, it does not solve the above-mentioned problems of continuous 24-hour stimulation, conductive fluid volatilization and tingling sensation
