Transcutaneous electrode with finger operative attachment assembly

摘要

A disposable electrode for direct transcutaneous derivation of patient biopotentials, such as the ECG of an unborn fetus, the active electrode element of which has a tuberous pin configuration with at least one tuberosity arranged along its length for enabling atraumatic attachment to and removal from the patient. The active electrode element may be of curved and multi-tuberous configuration for particularly facilitating application and firm attachment thereof substantially parallel to the skin surface. Several embodiments of disposable applicator are disclosed by which the sense of feel of the effort of and during application is retained. These include a flexible member elongated for easy grasping by the hand and having one end thereof designed to cooperatively engage the electrode for stability yet permit the physician's finger(s) to remain in contact with the electrode and a locking applicator arrangement which includes a displaceable locking piece enabling the electrode to firmly remain upon the applicator as the former is administered to the patient.
