Disposable patch electrode structure and connector of bio-signal measurement system, bio-signal measurement system and method of connecting with disposable patch electrode structure

Abstract

A disposable patch electrode structure comprises a front flap and a main structure, which is attached to skin for a bio-signal measurement, the patch electrode structure feeding electrical bio-signals to a bio-signal device separate from the patch electrode structure. The front flap is separated from the main structure by a non-enclosing front flap cut, material of the front flap being thus formed as continuous material of the main structure. Materialistic connection of the continuous material between a rear section of the front flap at a non-enclosing side of the front flap cut and the main structure allows tilt of the front flap with respect to the main structure in response to rise of a frontal section of the front flap with respect to the main structure. The front flap is fully surrounded by the main structure. The front flap comprises contact electrodes at the frontal section, the contact electrodes being both connected with measurement electrodes of the main structure through conductors via the materialistic connection and connectable with counter-electrodes of a connector separate from the patch electrode structure.
