First Claim
Patent Images
1. A nasal airway pressure system, comprising:
- a generator head configured to receive air for delivery to a patient, the generator head comprising;
an internal surface that defines an internal cavity configured to allow airflow therethrough, andan outer surface having a notch disposed between a lip and a convex external mount; and
a disposable patient nasal interface configured to couple to the generator head to provide airflow from the generator head to the patient, the disposable patient nasal interface comprising;
an internal surface that is configured to engage the outer surface of the generator head when the disposable patient nasal interface is coupled to the generator head, wherein the internal surface of the disposable patient nasal interface comprises a concave internal notch configured to receive the convex external mount of the generator head for coupling of the disposable patient nasal interface to 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.
