  • Patent number: 11975150
    Abstract: A device for delivering gas includes a frame, a gas delivery hose, and a noise reduction component. The gas delivery hose is detachably connectable to the frame. The noise reduction component includes a ventilation port and a muffler. The ventilation port is provided in communication with the cavity of the frame, and the muffler is connected to the frame and covers the ventilation port. The muffler has a first surface having a first breathable area exposed to the external environment, and a second surface having a second breathable area exposed to the cavity. The muffler also has multiple breathable channels connecting the first breathable area and the second breathable area, allowing gas in the cavity to be discharged from the muffler to the external environment. The multiple breathable channels in the muffler can disperse the gas flow, making it less turbulent and reducing the noise generated.

  • Patent number: 9669178
    Abstract: A patient interface device includes a patient sealing assembly having a cushion and a frame member having a faceplate portion and an extension portion extending from the faceplate portion. The cushion is coupled to the faceplate portion. A forehead member engages the forehead of the patient, and a flexible elongated member is coupled to the extension portion. A drive assembly selectively causes the second end portion of the flexible elongated member to move relative to the extension portion in a first direction. Movement of the flexible elongated member relative to the extension portion in the first direction causes movement of the frame member relative to the forehead member in a second direction transverse to the first direction.

  • Patent number: 9661989
    Abstract: An overtube device for use in intubation during an endoscopic procedure is disclosed. The device includes an outer tube and an inner tube. The outer tube includes a distal end, a proximal end, and a first handle disposed on the proximal end. The inner tube includes a distal end, a proximal end, and a second handle disposed on the proximal end. The inner tube is inserted through an entire length of the outer tube such that the inner tube extends beyond the outer tube. At the proximal end of the device, a proximal end of the first handle is connected to a distal end of the second handle. When the inner tube is co-axially inserted within the outer tube, a clearance exists between a length of the inner and outer tubes, and between a length of the inner tube and the endoscope. Methods of use are disclosed.

  • Patent number: 9592359
    Abstract: A respiratory mask assembly includes a respiratory mask including a mask shell and a mask cushion, a forehead support adjustably coupled to the mask, and an angular adjustment member. The forehead support includes a joining member provided to the mask shell and a cushion frame pivotally mounted to the joining member. The cushion frame is adapted to be selectively locked against pivotal movement in at least three predetermined angular positions relative to the joining member by a tongue and slot arrangement. The angular adjustment member allows relative angular adjustment between the cushion frame and the joining member. The angular adjustment member includes a pair of flexible arms that are adapted to be flexed towards one another to disengage the tongue from a respective one of the slots, and releasing the flexible arms allows the flexible arms to resiliently flex away from one another to engage the tongue and the respective slot.
