Abstract

This probe makes use of a simplified housing construction that significantly reduces the cost of the manufacture of the probe housing. The housing is implemented using two molded housing halves, which are pivotally connected together and which include an integral spring member. In addition, the housing includes a connector mounted thereon for enabling the probe to be disengaged from the cable and its associated connector that interconnects the probe with the medical monitoring equipment. As a further improvement, a notch is provided on the housing so that the conductors can be positioned to exit the probe in any direction to minimize the possibility of the conductors inadvertently pulling the probe loose from the patient'"'"'s finger.
