Abstract
The present invention relates to a physiological recording electrode, and, more particularly, to an EEG (electroencephalography) recording electrode that can be used without the need for numerous steps in preparing the subject's skin and the electrode itself. The invention further relates to a surface feature or penetrator with a size and shape which that will not bend or break, which limits the depth of application, and/or anchors the electrode or other device during normal application; and a packaging system comprising a well and electrolytic fluid for maintaining a coating of said electrolytic fluid on the surface feature or penetrator.
Claims20
A physiological recording device comprising:
- a packaging base layer comprising a well containing a porous material and electrolytic fluid infused in the porous material;
- and
- at least one physiological recording electrode comprising an adhesive collar and a physiological electrode comprising an upper and a lower surface, and at least one surface feature protruding from the lower surface of the physiological electrode,
- wherein the porous material holds the electrolytic fluid in contact with the at least one surface feature until the physiological recording electrode is removed for placement on a subject.
A physiological recording device comprising:
- a packaging base layer comprising a well containing a colloidal suspension;
- and
- at least one physiological recording electrode comprising an adhesive collar and a physiological electrode comprising an upper and a lower surface, and at least one surface feature protruding from the lower surface of the physiological electrode,
- wherein the colloid suspension is in contact with the at least one surface feature until the physiological recording electrode is removed for placement on a subject.
A physiological recording device comprising:
- a packaging base layer comprising at least one well containing a colloidal suspension or a porous material with electrolytic fluid infused in the porous material;
- and
- an array of at least two physiological recording electrodes comprising an adhesive layer, the physiological electrodes comprising a lower surface with at least one surface feature protruding from the lower surface,
- wherein the porous material holds the electrolytic fluid in contact or the colloidal suspension is in contact with the physiological electrodes' at least one surface feature until the array is removed for placement on a subject.
