Wet electrode electroencephalogram cap with detachable electrode and cap-connected injector

Abstract

The invention provides a wet electrode electroencephalogram cap with a detachable electrode and a cap-connected injector. A main body of the wet electrode electroencephalogram cap comprises a cap body, electrode matrixes, the detachable electrode and the cap-connected injector, the electrode matrixes arranged according to an international 10-20 system are fixed on the cap body, the electrode matrixes are used for fixing the detachable electrode, and the detachable electrode is connected with the cap-connected injector; the electrode matrixes are provided with hair poking combs which face the scalp and are used for poking hair, and convex fixing bolts are arranged at the tops of the hair poking combs; the detachable electrode comprises an electrode used for being attached to the scalp to collect electroencephalogram signals and an electrode wire used for transmitting the electroencephalogram signals; and the cap-connected injector comprises an injector inner cavity used for storing conductive paste, and a hose which communicates with the inner cavity and can output electroencephalogram paste is arranged at the bottom of the cap-connected injector. According to the wet electrode electroencephalogram cap with the detachable electrode and the cap-connected injector, the electroencephalogram detection efficiency is improved.

Description

technical field [0001] The patent of the present invention relates to the technical field of medical devices, specifically a wet electrode EEG cap with detachable electrodes and a capped syringe. Background technique [0002] EEG is a safe, non-invasive and low-cost detection technology that can directly reflect the activity of brain neurons. In clinical applications, EEG technology is widely used in the auxiliary diagnosis of central nervous system diseases and mental diseases based on the recorded physiological and pathological information, such as epilepsy, Parkinson's disease and brain death detection. [0003] The commonly used wet electrode EEG caps are wearable, and the electrodes used to record EEG activities are usually pre-fixed on the EEG caps, so there is no flexibility to change the detection area according to different detection targets. Secondly, before the test, the examiner needs to use a needle tube to inject EEG paste one by one into the electrodes that n...
