  • Publication number: 20250128007
    Abstract: A patient interface includes a plenum chamber, a seal-forming structure, and a positioning and stabilizing structure. The plenum chamber is pressurisable to a therapeutic pressure. The seal-forming structure is constructed and arranged to seal with a region of a patient's face surrounding an entrance to a patient's airways. The seal-forming structure maintains the therapeutic pressure in the plenum chamber throughout a patient's respiratory cycle in use. The positioning and stabilizing structure holds the seal-forming structure in a therapeutically effective position on a patient's head. The patient interface allows the patient to breathe from ambient in the absence of a flow of pressurised air. The positioning and stabilizing structure includes headgear, and at least a portion of the headgear and the seal forming structure is formed from a one piece construction of textile material.

  • Patent number: 12201771
    Abstract: The invention relates to a patient interface comprising a plenum chamber, a seal-forming structure, and a positioning and stabilizing structure, as well as the method of operating the patient interface. The patient's interface is configured to leave a patient's mouth uncovered or if the seal-forming structure is configured to seal around a patient's nose and mouth, the patient interface is configured to allow the patient to breath from the ambient in an absence of the flow of pressurized. The positioning and stabilizing structure includes headgear, and the seal-forming structure and at least a portion of the headgear is formed from a one piece construction of textile material. In another embodiment, the seal-forming structure and/or the positioning and stabilizing structure includes an adaptive portion that adjusts based on usage conditions.

  • Publication number: 20230181856
    Abstract: A patient interface including a seal-forming structure having a mouth portion that forms at least part of the mouth plenum and is configured to seal around the patient's mouth and a nasal portion that is configured to seal with the patient's nares. The patient interface further includes a vent structure with a main body that is configured to be secured to the mouth portion and includes a vent wall with a plurality of vent holes, a receptacle, and a pair of anchor sockets located on opposing lateral sides of the receptacle. A cover for the vent includes a pair of anchor pegs on lateral sides of the cover. The anchor pegs are configured to be inserted into the anchor sockets to secure the cover to the main body. A diffuser is received within the receptacle between the anchor sockets and is sandwiched between the main body and the cover.

  • Publication number: 20230087696
    Abstract: The present technology relates to a headgear for a patient interface, comprising one or more straps each having a first end for connecting to a mask. The first end of each strap comprises a connection portion which is grippable by a user to pull the strap to increase a tension in the strap, a first rigid member and a second rigid member that extends from a resilient carrier that is connected to the connection portion. The second rigid member is movable relative to the first rigid member when the connection portion is pulled. At least part of the second rigid member is arranged to strike the first rigid member to cause at least an audible alert when the second rigid member travels further than a threshold distance. The resilient carrier is constructed and arranged such that the threshold distance corresponds to a desired tension limit for the strap.

  • Patent number: 11471634
    Abstract: A patient interface including a seal-forming structure having a mouth portion that forms at least part of the mouth plenum and is configured to seal around the patient's mouth and a nasal portion that is configured to seal with the patient's nares. The nasal portion includes a nasal plenum positioned to receive pressurized gas from the mouth plenum. The seal-forming structure also includes a clip configured to connect the mouth plenum to the nasal plenum and act as a conduit for the flow of the pressurized gas from the mouth plenum to the nasal plenum. The clip includes a mouth portion end configured to engage the mouth portion, a nasal portion end configured to engage the nasal portion, and a pair of wings protruding from the nasal portion end into an interior of the nasal plenum so that the wings engage an interior surface of the nasal plenum.
