Abstract
An electrode assembly for sensing heart activity and especially heart activity from a fetal epidermis during the birth of a child. A fetal electrode introducer includes a rigid guide tube with an intermediate universal joint which allows the guide tube to be bent at the best angle to accommodate each patient. The intermediate joint allows a smooth transmission of the rotary motion manually applied at a distal handle to drive the electrode into the fetal epidermis. A sliding sleeve covers the fetal electrode to provide a bearing for rotation, protects the electrode from contamination, and also serves as a resistance means to indicate to the user that the assembly has abutted against the fetal epidermis. Such resisting means includes either a detent or lockable system, or a breakable membrane.
