Patient nasal interface for use with a nasal airway pressure system
First Claim
1. A patient nasal interface for use with a nasal airway pressure system, comprising:
- a female portion for receiving a male portion of a generator head configured to receive air pressure for both nostrils of a patient and for coupling with the nasal airway pressure system, wherein the female portion wraps around and over the male portion when the male portion is inserted into the female portion of the patient nasal interface;
a first registration feature formed from an internal notch in the female portion, wherein the first registration feature is configured for mating with a second registration feature associated with the male portion of the generator head and wherein the mating of the first registration feature with the second registration feature provides a first feedback to an operator upon proper insertion of the male portion into the female portion; and
an alignment feature formed by an external notch in the female portion, wherein the external notch extends from a lip of the female portion into a base of the female portion toward the internal notch, and wherein the external notch is configured to receive at least a portion of a port of the generator head to align the patient nasal interface with the generator head.

Abstract
A patient nasal interface is provided that includes a female portion and a first registration feature. The female portion receives a male portion of a generator head. The female portion wraps around and over the male portion when the male portion is inserted into the female portion of the patient nasal interface. The first registration feature is configured for mating with a second registration feature associated with the male portion of the generator head and wherein the mating of the first registration feature with the second registration feature provides a feedback to an operator upon proper insertion of the male portion into the female portion.

11. A nasal interface for use with a nasal airway pressure system, comprising:
-
a female portion for receiving a male portion of a generator head configured to receive air pressure for both nostrils of a patient and for connection with the nasal airway pressure system, wherein an inner surface of the female portion conforms to an outer surface of the male portion in a sealing area when the male portion of the generator head is properly inserted into the female portion of the nasal interface; an internal notch in the female portion for receiving an external mount associated with the male portion of the generator head, wherein the internal notch'"'"'s receiving of the external mount provides a first feedback to an operator upon proper insertion of the male portion into the female portion; and an alignment feature formed by an external notch in the female portion, wherein the external notch extends from a lip of the female portion into a base of the female portion toward the internal notch, and wherein the external notch is configured to receive at least a portion of a port of the generator head to align the nasal interface with the generator head. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A generator head for coupling with a patient nasal interface for use with a nasal airway pressure system comprising:
-
a male portion configured to receive air pressure for both nostrils of a patient and for insertion into a female portion of the patient nasal interface, wherein an inner surface of the female portion conforms to an outer surface of the male portion when the male portion is inserted into the female portion of the patient nasal interface; a first registration feature associated with the male portion, wherein a second registration feature associated with the female portion of the patient nasal interface is formed from an internal notch in the female portion and is configured for mating with the first registration feature associated with the male portion and wherein the mating provides a first feedback to an operator upon proper insertion of the male portion into the female portion; and a port coupled to the male portion and having a shape that corresponds to an external notch in the female portion of the patient nasal interface, wherein the external notch extends from a lip of the female portion into a base of the female portion toward the internal notch, and wherein the port and the external notch cooperate to align the patient nasal interface with the generator head. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
