Device for cardiac output monitoring

Claim 1

A single electrode assembly for cardiac output or other hemodynamic parameters output monitoring, comprising: a first pair of electrodes consisting of a first spot injection electrode adapted to be placed adjacent the xiphoid process with a backing and means, including a relatively small conductive strip on the backing, for injecting a first signal into the patient's body at the xiphoid process and a first elongated strip electrode adapted to be placed adjacent the xiphoid process with means, including an elongated first backing and an elongated conductive strip on the elongated first backing, for sensing the first signal when received at the xiphoid process; and a second pair of electrodes consisting of a second spot electrode adapted to be placed adjacent the neck with means, including a backing and a small conductive strip on the backing, for injection of a second signal into the patient's body at the neck, and a second elongated strip electrode adapted to be placed adjacent the neck with means, including an elongated second backing and an elongated conductive strip on the elongated second backing, for sensing the second signal when received at the neck; and a single connector assembly including a plurality of leads respectively connected to all the above electrodes at one end and commonly connected to a single connector at the other end and cable means attached to the connector for coupling both pairs of the electrodes to a monitoring apparatus.
