Abstract
Electrodes for use in electroencephalographic recording, including consciousness and seizure monitoring applications, have novel features that speed, facilitate or enforce proper placement of the electrodes, including aligning tabs and arrowed aligning juts, color coding, and an insulating bridge between reference and ground electrodes which ensures a safe application distance between the conductive regions of the two electrodes in the event of cardiac defibrillation or to prevent shorting between the adjacent electrodes by preventing the conductive path to be shared. A method of using a set of four such electrodes is also disclosed.
Claims20
A physiological device comprising an electrode, the electrode further comprising:
- a front, a back, and bottom, top, left and right sides;
- a conductive region surrounded by an insulating region on the back of the physiological electrode, the insulating region further comprising a handling tab adapted for placing the electrode on a subject;
- and
- a male snap connector on the front of the electrode adapted for connecting to an electrode lead,
- wherein the male snap connector is a non-standard male snap connector with the widest portion of the connector being between 2.5 mm and 3.65 mm in diameter,
- wherein the electrode lead comprises a female socket configured to mate with the male snap connector, and
- wherein insertion of a standard approximately 3.9 mm male snap connector into the female socket requires application of at least 12 N of axial force.
A method of applying at least three electrodes to a subject comprising steps of:
- providing at least three electrodes, one of the at least three electrodes comprising a front, a back, and bottom, top, left and right sides, a conductive region surrounded by an insulating region, and a male snap connector on the front,
- wherein the male snap connector of the one electrode is a non-standard male snap connector having a widest portion between 2.5 mm and 3.65 mm in diameter;
- applying the at least three electrodes to the subject's forehead;
- and
- placing a non-standard sized or shaped electrode lead over the corresponding non-standard male snap connector of each electrode and applying pressure until the lead snaps on to the connector,
- wherein the non-standard electrode lead comprises a female socket configured to mate with the male snap connector having a maximum dimension between 2.5 mm and 3.65 mm;
- and
- wherein insertion of a standard approximately 3.9 mm male snap connector into the female socket requires application of at least 12 N of axial force.
