Abstract
A patient interface for delivering breathable gas to a patient includes a sealing portion including a nose tip engagement portion adapted to form a seal with the patient's nose tip, an upper lip engagement portion adapted to form a seal with the patient's upper lip and/or base of the patient's nares, and nostril engagement flaps adapted to form a seal with the patient's nares. The nose tip engagement portion, the upper lip engagement portion, and the nostril engagement flaps are all structured to extend or curve outwardly from a supporting wall defining an air path.
Claims29
A patient interface for delivering pressurized breathable gas to a patient, the patient interface comprising:
- a sealing portion with an elastomeric sealing surface, the sealing portion including a nose tip engagement portion adapted to form a seal with an underside of the patient's nose tip, an upper lip engagement portion adapted to form a seal with the patient's upper lip and/or base of the patient's nares, and nostril engagement flaps adapted to form a seal with the patient's nares;
- and
- a supporting portion that supports and is more rigid than the sealing portion, the supporting portion terminating at a connection end that has an opening configured to receive a connector for an air delivery tube, a rim of the opening being configured to retain the connector for the air delivery tube,
- wherein the nose tip engagement portion, the upper lip engagement portion, and the nostril engagement flaps have different degrees of rigidity,
- wherein the elastomeric sealing surface at each of the nostril engagement flaps is thicker than the elastomeric sealing surface at the nose tip engagement portion and at the upper lip engagement portion, and
- wherein the sealing portion and the supporting portion together form at least part of an airflow path configured to convey the pressurized breathable gas and extending from the connection end of the supporting portion to the elastomeric sealing surface of the sealing portion.
A patient interface for delivering pressurized breathable gas to a patient, the patient interface comprising:
- a sealing portion with an elastomeric sealing surface, the sealing portion including a nose tip engagement portion adapted to form a seal with an underside of the patient's nose tip, an upper lip engagement portion adapted to form a seal with the patient's upper lip and/or base of the patient's nares, and nostril engagement flaps adapted to form a seal with the patient's nares;
- and
- a supporting portion that supports and is more rigid than the sealing portion, the sealing portion being integrally formed with the supporting portion, the supporting portion terminating at a connection end configured to connect to a connector for an air delivery tube, the connection end having a radially inwardly extending flange configured to retain the connector for the air delivery tube,
- wherein the elastomeric sealing surface at each of the nostril engagement flaps is thicker than the elastomeric sealing surface at the nose tip engagement portion and at the upper lip engagement portion, and
- wherein the sealing portion and the supporting portion together form at least part of a plenum configured to receive the pressurized breathable gas.
