Bipolar electrode structure for monitoring fetal heartbeat and the like

摘要: An improved electrode system for monitoring fetal heartbeat includes a curved guide tube adapted to be inserted through the vagina and cervix of woman in labor, retaining coil mounted on holder member which is slidably disposed tube, flexible driving rotate screw into epidermis two spaced electrodes are electrically connected suitable apparatus heartbeat. In first disclosed embodiment invention one pointed mounts coil. The coil, when screwed epidermis, maintains piercing engagement with fetus. second same structure, i.e., form epidermis. both embodiments from electrical contact between established by vaginal cervical secretions labor. Driving connection provided slots forward end fin means holder. flat rear serves as means.
