Abstract

A patient monitor can noninvasively measure a physiological parameter using sensor data from a nose sensor configured to be secured to a nose of the patient. The nose sensor can include an emitter and a detector. The detector is configured to generate a signal when detecting light attenuated by the nose tissue of the patient. An output measurement of the physiological parameter can be determined based on the signals generated by the detector. The nose sensor can include an inner prong and an outer prong to assist the nose sensor in securing to a patient'"'"'s nose. The detector can be coupled to an inner post of the inner prong and can be configured to secure to an interior or exterior portion of the patient'"'"'s nose.

Claims

an inner prong configured to be positioned on one of an inner or outer side of a nose, the inner prong including an inner post;

an outer prong configured to be positioned on one of an inner or outer side of a nose, the outer prong including;

a first outer post; and

a second outer post;

a detector configured to be secured to one of an inner or outer wall of the nose of the patient;

one or more light emitters configured to be secured to the other of the inner and outer wall of the nose of the patient; and

a coupling portion configured to space the inner prong from the outer prong, wherein the coupling portion provides support to the inner and outer prongs to secure the device to the nose of the patient.

2. The noninvasive physiological monitoring device of claim 1, wherein the first and second outer posts of the outer prong are curved to conform to a portion of the nose of the patient.

3. The noninvasive physiological monitoring device of claim 2, wherein the inner prong is curved to conform to a portion of the nose of the patient.
