ABSTRACT:
Apparatus and method for securely and stably fastening a probe such as a pH electrode to a patient such as a fetus undergoing labor, and a locking applicator tool arrangement for effecting the attachment of such apparatus. The fastening device is a generally cylindrical piece having a broad concave operative surface with a helical wire screw centrally protruding therefrom and a trio of small pods equispaced on the periphery thereof. An axial threaded hole extends from the concave surface through the rear portion of the device for accepting the probe. The rear portion of the device is configured to cooperate with the locking applicator tool arrangement which comprises an inner tubular member for holding the device in its one end and a concentrically arranged outer locking tubular member for controlling the locking and release of the device. The applicator assembly further comprises a stab tool configured to be applied to the patient through the holding tubular member and the fastening device and also an applicator member for effecting attachment of the probe to the fastening device through the holding tubular member.
