1. A noninvasive physiological monitoring device configured to be secured to a nose of a patient, the device comprising:
- an upper sensor body including a recess;
a lower sensor body;
an emitter configured to be secured to a wall of an alar region of the nose of the patient; and
a joint configured to rotatably couple the upper sensor body to the lower sensor body, the joint including;
an upper joint comprising a slot, wherein the upper joint extends from the upper sensor body towards the lower sensor body;
a first lower joint comprising a pin hole, wherein the first lower joint is positioned on a first side of the lower sensor body, and wherein the first lower joint extends from the lower sensor body towards the upper sensor body;
a second lower joint comprising a pin hole, wherein the second lower joint is positioned on a second side of the lower sensor body, and wherein the second lower joint extends from the lower sensor body towards the upper sensor body; and
a pin configured to extend through at least a portion of the slot of the upper joint and the pin hole of the first lower joint and the pin hole of the second lower joint,wherein the upper joint is positioned between the first lower joint and the second lower joint,wherein the slot of the joint allows the upper sensor body to rotate about a longitudinal axis of the device,wherein the joint prevents the upper sensor body from rotating about a transverse axis of the device, andwherein the transverse axis is perpendicular to the longitudinal axis.

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 diffuser. The diffuser 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 diffuser.

13. A method of calculating a measurement of physiological parameters of a patient, comprising:
-
transmitting light, by an emitter of a nose sensor, of at least first and second wavelengths through tissue of a nose of a patient; determining the measurement of the physiological parameters, by the nose sensor, based on the output signal, wherein the nose sensor includes; an upper sensor body including a recess; a lower sensor body; a joint configured to rotatably couple the upper sensor body to the lower sensor body, the joint including; an upper joint comprising a slot, wherein the upper joint extends from the upper sensor body towards the lower sensor body; a first lower joint comprising a pin hole, wherein the first lower joint is positioned on a first side of the lower sensor body, and wherein the first lower joint extends from the lower sensor body towards the upper sensor body; a second lower comprising a pin hole, wherein the second lower joint is positioned on a second side of the lower sensor body, and wherein the second lower joint extends from the lower sensor body towards the upper sensor body; and a pin configured to extend through at least a portion of the slot of the upper joint and the pin hole of the first lower joint and the pin hole of the second lower joint; wherein the emitter is configured to be secured to an inner wall of the nose of the patient, wherein the slot of the upper joint allows the upper sensor body to rotate about a longitudinal axis of the device, wherein the joint prevents the upper sensor body from rotating about a transverse axis of the device, and wherein the transverse axis is perpendicular to the longitudinal axis. - View Dependent Claims (14, 15, 16, 17)
