Claims29
An oronasal patient interface system adapted for the delivery of positive air pressure to an individual, comprising:
- a nasal interface portion comprising a first resilient elastomeric hollow chamber body defining a first space-filled interior chamber, the first hollow chamber body comprising
- a concave, bowl-shaped, skin contact surface configured to receive the nose of the individual, wherein the skin contact surface comprises a superior margin configured to contact the individual's skin at the supratip lobule and terminate contact of the unitary chamber with the individual's skin at or inferior to the supratip break, and an inferior margin configured to contact the individual's skin inferior to the coumella and superior to the upper vermillion border,
- a surface recess in the skin contact surface positioned inferior to the superior margin and configured to receive the individual's tip lobule,
- a pair of nasal interfaces, each nasal interface comprising an opening at an upper surface thereof in fluid communication with the space-filled interior chamber, and
- first and second elastomeric side members, each side member configured to extend laterally from the resilient elastomeric hollow chamber body and comprising an interior surface recess in the second surface region configured to receive the individual's alar rim, wherein each side member is configured to contact the individual's skin and extend over a nasal ala towards a position overlying the maxilla and terminate contact of the first hollow chamber body with the individual's skin proximal to the zygomaticomaxillary suture;
- an oral interface portion configured to define a plenum space over the mouth of the individual, the oral interface comprising a perimeter surface providing a seal-forming structure configured to form a seal with a region of the patient's face surrounding an entrance to the patient's airways and extend around and under the mental protuberance of the individual to envelop the chin of the individual;
- and
- a gas ingress port configured to operably connect to a source of pressurized gas,
- wherein the plenum space and the hollow chamber body are each configured in fluid communication with the gas ingress port and with each other such that pressurized gas entering the unitary apparatus through the gas ingress port is delivered to the individual's airway via the plenum space and the nasal interfaces in the hollow chamber body.

- first and second hollow elastomeric side members, each side member configured to extend laterally from the resilient elastomeric hollow chamber body such that the hollow interior of the elastomeric side members is fluidly continuous with the hollow interior of the hollow chamber body, wherein each side member comprises
- a third surface region configured to contact the individual's skin and extend over a nasal ala towards a position overlying the maxilla and terminate contact of the unitary chamber with the individual's skin proximal to the zygomaticomaxillary suture, and
- an interior surface recess in the second surface region configured to receive the individual's alar rim;
- and
- one or more exhaust apertures through the chamber body that fluidly connect the space-filled interior chamber to ambient external atmosphere.
