Abstract

Electrodes as for use in taking electrocardiograms are provided in a multiple electrode pad formed as an elongate, narrow, curved strip with the electrodes arranged in a curvilinear relation to one another. The pad readily assumes the shape of the thorax or chest of a man, woman, or child at several desirable application sites, such as precordially, for routine or emergency use. The strip may be perforated or otherwise weakened in lines between the electrodes for tearing of the strip to separate the electrodes for individualized placement.

Claims

1. An electrode pad comprising a thin, flexible, narrow, generally flat, and elongate strip having two opposite faces bounded by common edges including two curvilinear edges opposite one another and extending the elongate length of the strip, the pad being adapted to be applied to the chest or thorax of a patient as for electrodcardiography, wherein the strip carries a plurality of electrodes spaced apart along such strip on one face thereof, whereby the strip may readily and without stretching assume the curved contour of a patient'"'"'s body upon application of said strip thereto.

2. An electrode pad as defined in claim 1, wherein the strip is formed with a line of weakened material extending substantially from one face to the other through the strip and from one curvilinear edge to the other across the strip and between adjacent electrodes, whereby to facilitate separation of the electrodes of the pad as by tearing for individualized placement of each of said electrodes.

3. An electrode pad as defined in claim 1 or claim 2, wherein the strip carries at least three electrodes and the electrodes are spaced in a curvilinear relation to one another along the strip.

4. An electrode pad comprising a flexible, generally flat material with opposite faces and formed as a strip and bearing a plurality of electrodes, the pad having two opposite generally flat surfaces comprising said opposite faces, said surfaces being bounded by common edges including two opposite generally parallel curvilinear sides, wherein the pad is adapted for application to curved portions of the chest or thorax of a patient, and wherein:

the pad is formed as an elongate, narrow strip carrying on one of its surfaces at least three electrodes; and

the electrodes are spaced apart from one another on such strip along a curved line which extends generally parallel to and between the curvilinear sides of the pad,

whereby to facilitate application to a patient.

5. An electrode pad as defined in claim 4, wherein any of said electrodes is separable from an adjacent electrode via a line of weakened material extending through and across the pad between said electrode and said adjacent electrode and wherein each said electrode has a conductive wire integrally attached thereto, said wire engaging the electrode pad only on a side of the weakened line adjacent such electrode, whereby fully to facilitate separation of such electrode from the rest of the electrodes in said pad.
