First Claim
Patent Images
1. An optical method for determination of a blood characteristic comprising the steps of:
- applying an emitter and detector to spaced-apart positions on a heel of a patient in the region of the calcaneus bone;
securing said emitter and detector to said patient;
emitting electromagnetic radiation with said emitter;
detecting electromagnetic radiation scattered by said heel with said detector and producing a detector signal; and
determining a blood characteristic in said patient from said detector signal.

Abstract
An improved infant/neonatal pulse oximeter sensor substrate which is preferably conforming to the shape of the infant or neonate'"'"'s foot. In one embodiment, the pad conforms to the heel of the infant, with the emitter and detector preferably being mounted in the region of the calcaneus bone. The heel pad can be held in place with a stretchable sock. In an alternate embodiment, the conformable pad is a sock with recesses or pockets cut in it for holding the emitter and detector.
