Abstract

A physiological test probe, in particular a vaginal electrode for the derivation of the foetal electrocardiogram, adapted to be transcervically fixed by means of points to the skin of the foetal head and attached to an output conductor cable. The probe may be a clip having a pair of planar parallel legs extending from a partially circular spring portion and having inwardly directed punctiform teeth on the free ends thereof, or may be provided with invasive contact points which are obliquely angled forwards from the longitudinal probe axis and ensure a good contact and as little damage as possible inflicted to the skin tissue of the foetal head. This probe is suitable for mounting elements associated with further measuring systems in order to allow remote instrumentally monitored observation of the birth process. The clip legs of one embodiment are mutually elastically connected and terminally provided with teeth so that on relaxation of the spring a skin fold is drawn into the gap between the clip legs and the skin fold is firmly held at a defined contact pressure.
