Abstract

A measuring head is described for mounting at or within parts of the human body, especially for obtaining ECG signals from a fetus. The measuring head includes electrodes separated from each other and connected to separate leads, in the form of two pointed opposite catchers mounted in an isolating carrier. A cannula may be provided so that liquid medicine or an electrolyte can be supplied to the body at the point of measurement.

Claims

1. An apparatus for obtaining measurement signals at or within cavities of the human body, comprising a carrier formed from an electrically insulating material;

a spiral catcher supported by said carrier, said catcher comprising two electrodes in the form of two catcher arms which are electrically isolated from each other and positioned to extend beyond the carrier, one end of each arm being connectable to an electrical signal lead and the other end of each arm terminating in a pointed shape, the pointed ends being displaced 180* relative to each other.

2. The apparatus of claim 1, including at least one tube positioned within the carrier, one end of said tube protruding beyond the end of the carrier, the other end of said tube being connectable to a liquid line.

3. The apparatus of claim 2 wherein the tube protruding beyond the end of the carrier is pointed and is positioned centrally between the spiral arms.

4. The apparatus of claim 3, wherein the tube protruding beyond the carrier includes a portion which is adjustable in length.

5. The apparatus of claim 2 wherein one of the catcher arms is formed from a tube, and is connectable to a liquid line.
