ELECTRODE DEVICE FOR MEASURING BIOPOTENTIALS Russian patent published in 2007 - IPC A61B5/408 A61B5/478 A61B5/492 

FIELD: medical engineering.

SUBSTANCE: device has electrode having current-collector enclosed into electric insulating casing having cavity fillable with electric conducting gel connected to output wire and setting socket fixed on flexible holder. The socket has hollow base and hollow inlay inserted one into the other. Electrode casing is shaped as hollow cylinder having flange with corrugating tail on one end and containing the output wire. The second end face has spherical thickening. Hollow inlay has crimp seal bent inside, available on the end touching the base. Collet clamp is available on the crimp seal shelf. The clamp is shaped as hollow cylinder which end face has internal rib. The current-collector is shaped as hollow cylinder which internal diameter is equal to the internal diameter of electrode casing. Internal diameter of cylindrical collet clamp part is equal to maximum ball-shaped electrode casing thickening diameter, cylindrical part height is greater than insert length. Internal diameter of cylindrical collet clamp part is equal to external diameter of cylindrical electrode casing part. External part of setting socket inlay has annulet and internal surface of the setting socket has groove. The annulet and groove are members of inlay-to-base engagement. Internal diameter of base differs from external insert diameter by electrode holder fabric thickness. The base and inlay of setting socket and electrode casing are manufactured by pressing, from high density polyethylene.

EFFECT: high reliability and operation usability.
