Electroencephalogram cap and electroencephalogram acquisition method

Abstract

The invention provides an electroencephalogram cap and an electroencephalogram acquisition method. The electroencephalogram cap comprises a main body used for being arranged on a head in a sleeving mode, at least one electric acquisition assembly and a plug used for being connected with external equipment; each electric collection assembly comprises an electrode holder and an electrode set; the electrode holder is fixedly arranged on the surface of the main body; the electrode set is detachably connected with the electrode holder; the electrode holder is provided with a conductive device and alead; the conductive device is used for collecting scalp potential information; two ends of the lead are connected with the conductive device and the plug respectively; a second hole suitable for conductive paste to pass through is formed in the conductive device; the electrode set comprises a conductive paste cavity and an electrode contact; the conductive paste cavity is used for storing the conductive paste; the electrode contact communicates with the interior of the conductive paste cavity; a first hole suitable for the conductive paste to pass through is formed in the electrode contact;and the structure of the electrode contact is suitable for being fixed to and electrically communicating with the conductive device. The electroencephalogram acquisition method comprises the steps ofinstallation and adjustment, work starting, electrode set position adjustment and the like. According to the electroencephalogram cap and the electroencephalogram acquisition method, the use convenience of the electroencephalogram cap is improved.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to an EEG cap and an EEG collection method. Background technique [0002] In clinical applications, many cranial nerve diseases, such as epilepsy, mental illness, sleep disorders, etc., need to obtain physiological and pathological information by recording EEG signals. The scalp EEG acquisition system is usually called an EEG cap, which records bioelectrical signals through electrodes fixed on the scalp, and is connected to a signal amplifier and an analog-to-digital converter for EEG signal recording. [0003] At present, the most commonly used EEG recording method in hospitals is to use conductive paste to directly fix the electrodes. Although this design is accurate in positioning, the operation process is time-consuming and labor-intensive due to the need to paste the electrodes one by one during use. At the same time, the placement of the electrodes depends on profess...
