Abstract: A sensor placement and retention mechanism for use with fetal sensor sites beyond the user's reach are disclosed. The preferred embodiment of this invention is a fetal pulse oximetry sensor (2,200) having an active face (4) through which a light source (6) and a light detector (8) operate. The sensor includes a handle (15) that facilitates placement of the active face at a sensor site in a preferred region beyond the transcervical region and beyond the reach of the user. A pair of electrodes (210,212)--one disposed against the fetus' skin (211) and one exposed to the amniotic fluid--are used to confirm that the sensor is firmly in place on the fetus. In an optional sensor retention feature, a self-inflating bladder (40) presses the active face of the sensor against the fetus' skin to optically couple the sensor with the tissue at the sensor site.

Abstract: An intrauterine pulse oximetry apparatus and method are provided to measure foetal blood oxygen saturation at sites in a preferred region on the foetus. The sensor (103) of the apparatus (100) is attached to a stiff cable (102) which can be inserted into the uterus past the presenting part and transcervical region of the foetus. The cable may have visual and tactile markings (107, 108) by which the user, without seeing or feeling the sensor, can guide it to an appropriate site on the foetus.
