Perforated size adjustable biomedical electrode
First Claim
1. A biomedical electrode comprising:
- a pad comprising a first portion, a second portion, and a predefined means for detaching said second portion from said pad, so that said pad with said second portion comprises a first surface area for contacting a patient'"'"'s skin and upon detaching said second portion from said pad, said pad comprises a second surface area for contacting the patient'"'"'s skin, said predefined means for detaching peripherally extending around said first portion; and
an electrode attached to said first portion of said pad.

Abstract
A perforated biomedical electrode having a detachable portion which allows a clinician to remove a portion of the electrode to thereby reduce the effective contact size of the electrode, e.g., the effective surface area for adhering the electrode to the patient'"'"'s skin and/or the effective surface area for establishing electrical contact or ground with the patient'"'"'s skin depending on the particular application, e.g., for use on an adult or a child. The biomedical electrode includes a pad comprising a first portion and a predefined line of separation along which a second portion of the pad is detachable from the pad so that the pad initially comprises a first surface area for contacting a patient'"'"'s skin and upon detaching the second portion from the pad, the pad comprises a second surface area for contacting the patient'"'"'s skin. An electrode attaches to the first portion of the pad. Desirably, a series of slits peripherally extends around the first portion and through the pad to define the predefined line of separation. A layer of adhesive may be applied on the first surface area and a protective cover sheet may be provided for protecting the layer of adhesive. The perforated biomedical electrode may also include a top non-electrically conductive foam layer, an electrically conductive metal foil layer, and a layer of electrically conductive adhesive.
