Abstract
A fetal pulse oximeter sensor mounted on a sensor head with an articulating design. A lumen on one side of the sensor has a cable or rod therein to either push or pull that side of the sensor with respect to the main body, thus causing the sensor head to articulate. This can be used, for instance, to apply pressure against the fetus' scalp, with the sensor head, using the articulating mechanism, until an adhesive takes hold. Additionally, the sensor may be held in place on the fetus by an adhesive which is appropriate for a wet surface. The adhesive has the characteristics of having sufficient adhering characteristics to maintain the sensor in place, while at the same time not damaging the fetus' skin upon removal, without requiring suction.
