Abstract

A multielectrode system for surface registering of electric heart potentials comprising electrodes which are in an elastic holder of electrodes arrranged slidably and are maintained in their position by a clamping device, enabling a quick adjustment of the position of each electrode with respect to the elastic electrode holder in order to achieve a good contact with the surface of the body of a patent.

Claims

1. A multielectrode system for surface registering of electric heart potentials comprising

a plurality of electrically conductive tubes, each of said tubes having an upper part and a lower part;

a corresponding plurality of resilient contact bodies, each resilient contact body being inserted into the lower part of a corresponding one of said conductive tubes;

means for fixing said resilient contact bodies to said tubes;

a corresponding plurality of insulating pins, each of said pins being fixed to the upper part of a corresponding one of said tubes;

an elastic multielectrode holder, said holder being provided with a plurality of openings, with insulating inserts penetrating said openings and fixed to said holder;

said insulating inserts provided with openings corresponding to the external diameter of said conductive tubes;

each one of said conductive tubes being embraced by one of said insulating inserts whereby said tubes are slidable through the openings of said inserts;

a plurality of clamping means, each of said clamping means being adapted to retain one of said tubes in a desired position in one of said insulating inserts.

2. A multielectrode system for surface registering of electric heart potentials as claimed in claim 1, wherein each of said electrically conductive tubes have a surface and said surface is silver.

3. A multielectrode system for surface registering of electric heart potentials as claimed in claim 1, wherein each of said clamping means comprises a spring collet, the lower part of which is fixed to a corresponding on of said insulating inserts of the elastic multielectrode holder, the upper part of said collet resting against the insulating pin inserted into the conductive tube of the electrode.
