Forehead sensor placement
First Claim
1. An oximeter sensor, comprising:
- a substrate having a shape similar to a shape of at least a portion of a patient'"'"'s forehead and including a section adapted to directly contact a portion of a forehead of a patient, wherein the section adapted to directly contact a portion of a forehead of a patient has an arcuate shape when placed flat upon a planar surface in the absence of any restraining force;
an emitter disposed on the substrate at a position located on the section;
a detector disposed on the substrate at a distance from the emitter wherein both the emitter and the detector are disposed to one side of an imaginary line that bisects the substrate through its arc; and
a headband for holding the substrate against the patient'"'"'s forehead, the headband sized to fit around the patient'"'"'s head.

Abstract
Forehead oximetry sensor devices and methods for determining physiological parameters using forehead oximetry sensors. One method includes placing an oximetry sensor on the forehead of a patient, such that the sensor is placed on the lower forehead region, above the eyebrow with the sensor optics placed lateral of the iris and proximal the temple; and operating the pulse oximeter to obtain the physiological parameter. In one aspect, the method also includes providing and placing a headband over the oximetry sensor, or alternately, the sensor is a headband-integrated sensor. The headband has an elastic segment sized to fit around the patient'"'"'s head. The headband also includes a non-elastic segment that is smaller than and attached with the elastic segment. The non-elastic segment is sized to span a portion of the elastic segment when the elastic segment is stretched. In addition, the non-elastic segment is larger than the portion of the elastic segment it spans when the elastic segment is not stretched. When the headband or the headband-integrated sensor is sufficiently tight, it delivers a pressure in the range higher than the venous pressure and lower than the capillary pressure to the forehead of the patient.
