Multielectrode system for surface registering of electric heart potentials

DETAILED DESCRIPTION We claim: 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.




Description:
FIELD OF THE INVENTION The invention relates to electrodes and a multielectrode system for surface registering of electric heart potentials.
BACKGROUND OF THE INVENTION For picking up heart potentials by the noninvasive method, it is known to use either independent electrodes where each electrode is separately fixed on the body surface, or a number of electrodes, mounted on suitable elastic holders
