Specially configured lip/cheek pulse oximeter/photoplethysmography probes, selectively with sampler for capnography, and covering sleeves for same
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 said 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.
