Embodiment Construction

[0029] Such as figure 1 , figure 2 As shown, the electrode cap 1 that can be deformed according to the shape of the patient's skull in this embodiment includes an electrode assembly 100 and an electrode cap body 200;

[0030] The electrode cap body 200 is cap-shaped, and in the actual manufacturing process, three basic sizes of the electrode cap body 200 suitable for infants, juveniles and adults can be manufactured.

[0031] The electrode cap body 200 includes a frame body 210 and an insulator 220 covering the outside of the frame body;

[0032] The frame body 210 is a hollow mesh structure made of soft insulating material with no fixed shape, such as cloth, silicone rubber, plastic, etc.;

[0033] The frame body 210 of the network structure is composed of tubular bodies 212 and node points 211, wherein the node points 211 are distributed at the positions where each tubular body 212 is connected to each other and penetrate each other;

[0034] The bottom of the frame bod...

Abstract

The present invention provides a high-conductivity electrode cap suitable for an electromyogram evoked potentiometer. The high-conductivity electrode cap comprises an electrode cap body and an electrode assembly, wherein the electrode cap body is in a cap shape and comprises a frame body and an insulating body covering the outer side of the frame body; the frame body is of a hollow mesh structure which is made of soft insulating material with no fixed shape, is provided with a plurality of nodal parts and of which the bottom is provided with a line outlet end; the electrode assembly comprises at least one electrode; the end of each electrode is connected with a signal line assembly; the electrodes are arranged in the nodal parts; the signal line assemblies are uniformly arranged in the mesh structure and comprise signal lines and memory alloy; the electrodes are connected by the signal lines, and all of the signal lines are finally gathered at the line outlet end; and the memory alloy is of a linear structure, and is attached to the outer sides of the signal lines. By the adoption of the structure, the effect that the electrode cap can naturally recover to the original shape after being used is realized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a high-conductivity electrode suitable for an electromyography-evoked potential instrument. Background technique [0002] EEG measurement is a common medical diagnosis method, and physiological and pathological information can be obtained through EEG signals. EEG measurements could also provide an important signal source for emerging wearable devices. EEG measurement is to place electrodes at a certain position on the head, form a stable micro-electric detection channel through conductive glue, accurately obtain weak bioelectricity, and collect the bioelectricity activity of the human head through electroencephalograph and other EEG equipment , amplification, signal processing, display and record its waveform. [0003] The EEG electrode cap plays the role of fixed electrodes and accurate positioning during EEG measurement, and detects the weak current of the head through the elec...
