Abstract

A patient interface for communicating fluids to and/or from a patient'"'"'s nasal cavity and/or oral cavity is disclosed. In addition, a patient interface for fluid and physiological function monitoring proximate to the patient'"'"'s nasal cavity and/or oral cavity is disclosed. An apnea monitor and a method for monitoring apnea are also disclosed.

Claims

1. A patient interface comprising:

a body portion configured to communicate with a first fluid path;

a first nostril interface extending from the body portion, wherein the nostril interface communicates with the first fluid path; and

a first securement portion extending from the body portion proximate the nostril interface, wherein the securement portion is constructed and arranged to engage an exterior surface of a patient'"'"'s nose to secure the patient interface to such a patient'"'"'s nose.

2. A patient interface according to claim 1, wherein the securement portion is biased toward the first nostril interface responsive to the securement portion being disposed on the patient'"'"'s nose.

3. A patient interface according to claim 1, further comprising a first tubing that defines the first fluid path.

4. A patient interface according to claim 3, further comprising a strap coupled to the tubing and adapted to support the tubing, the strap being configured to be received by an ear of a patient.

5. A patient interface according to claim 1, wherein the body portion is communicates with a second fluid path and further comprising a second nostril interface extending from the body portion and operatively coupled to the second fluid path.

6. A patient interface according to claim 5, further comprising

a first tubing that defines the first fluid path;

and

a second tubing that defines the second fluid path.

7. A patient interface according to claim 6, further comprising a strap for supporting the second tubing, the strap being configured to be received by an ear of the patient.

8. A patient interface according to claim 5, wherein the second nostril interface is configured and arranged to remain below a patient nose responsive to the patient interface being worn by such a patient, and includes at least one orifice defined therein to delivery fluid to or receive fluid from such a patient.

9. A patient interface according to claim 1, further comprising a physiological function sensor connected with the first securement portion for engagement with the skin of a nose of such a patient, and wherein the physiological function sensor generates a signal based on a physiological function measurement.

10. A patient interface according to claim 9, wherein the sensor comprises an emitter for emitting a signal and a detector for detecting the signal.

11. A patient interface according to claim 10, wherein the emitter comprises at least one light source and the detector comprises a photodetector.

12. A patient interface according to claim 1, further comprising a second securement portion constructed and arranged to engage an interior surface of a patient'"'"'s nose such that a portion of a nose is disposed between the first securement portion and the second securement portion.

13. A patient interface according to claim 12, further comprising a physiological function sensor connected with the first securement portion, the second securement portion or both for engagement with the skin of a nose of such a patient, and wherein the physiological function sensor generates a signal based on a physiological function measurement.

14. A patient interface according to claim 13, wherein physiological function sensor is disposed on the first securement portion, the second securement portion or both such that (a) the emitter engages an external surface of a portion the nose and the detector engages an internal surface of a portion of the nose, (b) the detector engages the external surface of a portion of the nose and the emitter engages the internal surface of a portion of such nose, (c) the emitter and the detector both engage the external surface of the nose, or (d) the emitter and the detector both engage the internal surface of the nose.

15. A patient interface comprising:

an appliance portion including a nostril interface, the nostril interface being configured to be received by a patient'"'"'s nostril and to provide fluid communication between the nostril and a fluid path; and

a physiological function sensor connected with the appliance portion for engagement with the skin of the nose of the patient and generating a signal based upon a physiological function measurement.

16. A patient interface according to claim 15, wherein the sensor comprises an emitter for emitting a signal and a detector for detecting the signal.

17. A patient interface according to claim 15, wherein the appliance portion also includes:

a body portion configured to communicate with the fluid path; and

a securement portion extending from the body portion, wherein the securement portion is disposed proximate the nostril interface and constructed and arranged to engage an exterior surface of the patient'"'"'s nose, and wherein the nostril interface and the securement portion cooperate to secure a portion of the patient'"'"'s nose therebetween.

18. A patient interface according to claim 17, wherein at least a portion of the sensor is disposed on the securement portion such that the portion of the sensor engages the exterior surface of the portion of the patient'"'"'s nose.

19. A patient interface according to claim 18, wherein (a) the emitter and the detector are disposed on the securement portion and engage the exterior surface of the patient'"'"'s nose, (b) the emitter is disposed on the securement portion and engages the exterior surface of the patient'"'"'s nose and the detector is disposed within the nostril and engages an interior surface of the portion of the patient'"'"'s nose, (c) the detector is disposed on the securement portion and engages the exterior surface of the patient'"'"'s nose and the emitter is disposed within the nostril and engages an interior surface of the portion of the patient'"'"'s nose, or (d) the emitter and the detector are disposed within the nostril and engage the interior surface of the patient'"'"'s nose.

20. A patient interface according to claim 15, wherein the emitter and the detector are biased toward each other.
