Shower electrode based evoked potential detector

Abstract

The invention discloses a shower electrode based evoked potential detector, which comprises an electrode fixing device for fixing electrodes to a human head. At least one shower electrode in contact with scalp is mounted on the electrode fixing device and is connected with a receiving device through a transmission cable. The area of contact of the electrodes of the detector with human scalp can be increased, the detector is easier to contact with the scalp through human hair, the electrodes are guaranteed to stably contact with the human scalp through a plurality of contact teeth, impedance reduction and signal quality improvement are achieved by the aid of circular electrodes compared with the shower electrodes of the detector, no electrode gel is not needed, and accordingly service cost is reduced, use convenience is improved and the scalp cannot be dirtied after detection. Noninvasive detection can be achieved by the aid of the shower electrodes compared with pin electrodes, and a user feels no pain when using the detector.

Description

technical field [0001] The invention belongs to the field of biomedical signal processing and medical equipment, and in particular relates to an evoked potential detection device based on a shower electrode. Background technique [0002] In clinical medicine, electrophysiological examination is an extension of nervous system examination, in which evoked potentials can be used to determine the functional status and suspicious lesions of the peripheral neuromuscular system and central nervous system, detect subclinical lesions, and accurately locate lesions. [0003] When using evoked potential instrument to detect evoked potential, in the past, disc electrodes or needle electrodes are usually used to detect the head of the human body. Among them, the disc electrode uses electrode gel to wrap the hair and contacts the scalp, while the needle electrode uses an invasive method. Directly inserted into the human scalp for detection, the disc electrode not only has a high cost of e...

[0003] When using evoked potential instrument to detect evoked potential, in the past, disc electrodes or needle electrodes are usually used to detect the head of the human body. Among them, the disc electrode uses electrode gel to wrap the hair and contacts the scalp, while the needle electrode uses an invasive method. Directly inserted into the human scalp for detection, the disc electrode not only has a high cost of electrode gel, but also because the electrode gel surrounds the hair, the input impedance is large and the signal quality is not ideal, and the needle electrode needs to be inserted into the human scalp. human trauma
