First Claim
1. A probe for measurement of pulse-based differences in light absorbence across the vascularized tissue of a lip or a cheek of a patient, comprising:
- a. a resilient probe frame having an inner face and an outer face, said frame comprising a proximal arm connecting at one end to a cable and at the other end to a bridging section of said frame, said bridging section connecting the proximal arm to one end of a distal arm of said frame, wherein a portion of said distal arm is at a determined distance from an opposing portion of said proximal arm;
b. a first pad positioned over at least two light-generating structures that emit light at at least two different wavelength bands known to differentiate oxygenated from non-oxygenated hemoglobin, on the inner face of said portion of the distal arm or of the proximal arm;
c. a second pad positioned over at least one light-detecting structure that detects light transmitted from said first pad, on the inner face of the arm opposing the first pad; and
d. first individual conductors for energizing said at least two light-generating structures, connecting said structures to a monitoring system for light signal production and modulation, and second individual conductors connecting said at least one light-detecting structure to said monitoring system to convey signals of light detected by said at least one light-detecting structure, said first and said second individual conductors passing within said resilient probe frame and thereafter through a cable for carrying said first and said second individual conductors to said monitoring system.

Abstract
The present invention relates to novel lip/cheek probes for detection of pulse-based differences in light absorbence across the vascularized tissue of a lip or cheek of a patient. These probes are fabricated to provide signals to estimate arterial oxygen saturation, and/or to obtain other photoplethysmographic data. The present invention also relates to a combined probe/cannula. The present invention also relates to other devices that combine a pulse oximeter probe with a device supplying oxygen or other oxygen-containing gas to a person in need thereof, and to sampling means for exhaled carbon dioxide in combination with the novel lip/cheek probes. In certain embodiments, an additional limitation of a control means to adjust the flow rate of such gas is provided, where such control is directed by the blood oxygen saturation data obtained from the pulse oximeter probe.
