  • Patent number: 10946158
    Abstract: The present invention relates to a device for delivering a supply of gases to a patient. The device includes a patient interface and connecting member. The connecting member is preferably a L-shaped swiveled connector that is capable of being fixed into one of two positions, a first position where the connector is freely rotatable within the patient interface, and a second position where an interference between the interface and connector prevents the free rotation of the connector within the patient interface. The present invention further relates to a connector that has outlet means, which includes at least one outlet vent and a funnel, which in use directs and passes a substantial portion gases expired from the patient through the outlet vent or vents.

  • Publication number: 20200222654
    Abstract: A respiratory interface, such as a mouthpiece, having a vestibular shield overlapping a user's teeth and gums, a gases passageway extending through the vestibular shield allowing for the passage of the gases through mouthpiece and an extra oral seal associated with the gases passageway, wherein the passageway in use causes gases to be diffused when exiting from the gases passageway. Mouthpiece may have an adjustment mechanism to alter distance between the vestibular shield and the extra-oral seal. The interface may include an elbow having a vent.
