Abstract: An oximeter sensor formed with a housing made of a relatively rigid material into which the oximeter electrical components can be mounted is provided. An overmolded material, of lesser rigidity, is injection-molded over the housing to complete the sensor. In one embodiment the housing is made of plastic, such as polypropylene, and the overmolded material is an injection-molded thermal plastic elastomer, such as Santoprene

Abstract: A fetal pulse oximeter sensor (22, 24) is mounted on a sensor head (10) with articulating means comprising a cable (26) or rod, lodged in a lumen (36) on one side of the sensor to either push or pull that side of the sensor with respect to the main body, thus causing the sensor head to articulate. By using the articulating mechanism, the sensor head can be applied with pressure against the fetus' scalp, until an adhesive (34) takes hold, preferably an adhesive which is appropriate for the wet surface. The adhesive has sufficient adhering properties to maintain the sensor in place, without requiring suction, while at the same time does not damage the fetus' skin upon removal.
