Abstract
Abstract An oximeter probe is introduced through the vaginal canal and applied to the scalp or other readily accessible part of the fetus while still in utero. The fetal oxygenation is monitored during the entire labor and delivery period to obtain instantaneous indications of any peripartum fetal distress. The probe comprises a clamping device which can be easily manipulated within the narrow confines of the partially dilated cervix.

Claim 1
Independent Claim
139 words
In combination with a blood oxygenation measurement apparatus, a vaginal probe for attachment to a fetus in utero, said probe comprising: a pair of resiliently openable, interfacing jaws, a first of said jaws having at least one light emitter and a second of said jaws having at least one light detector in line with said light emitter, an elongated handle having an undersurface arcuate to an axis substantially parallel to and spaced apart from the largest dimension of said handle sized and shaped to rest against the surface of an attending person's finger, said handle extending from one of said jaws, an elongated lever extending from the other of said jaws parallely to said handle and having a fulcrum point on an upper surface portion of said handle; and a resilient means for baising the jaws towards each other.
