Electrode junction assembly
First Claim
1. An electrical junction block for use with a fetal electrode and electronic monitor comprisinga housing having sides and having a cavity therein,a substantially U-shaped spring disposed in the cavity, and having post members extending through the sides of the housing to enable the spring to be depressed by fingers of a person, the spring having legs terminating in angled ends disposed adjacent angled members of the housing defining therebetween a pair of guide entries for receiving the ends of electrical conductors of a fetal electrode, andelectrical contacts connected with the housing adjacent the guide entries for electrically connecting with conductors of an electrode, and wires connecting the contacts and adapted to be connected to an electronic monitor.

Abstract
There is disclosed herein an electrical junction block particularly for use with a fetal electrode and electronic monitor. The junction block comprises a housing having a cavity therein, and a substantially U-shaped spring disposed in the cavity. The spring has legs which are biased outwardly by a suitable coil spring. The housing contain electrical contacts and wires connected thereto, and the U-shaped spring can be depressed to provide openings for receiving electrode wires. A mounting pad can be disposed on the housing for facilitating mounting of the assembly on a person during use.
