20140069429 | SENSOR AND VALVE INTEGRATED INTO A PATIENT INTERFACE - An improved patient interface assembly and pressure support system integrate a pressure sensor and a valve into the patient interface assembly and employs closed loop control between the sensor and the valve in order to limit delay between the time at which a condition indicative of abnormal breathing or flow load during normal breathing is experienced by a patient and the time at which altered pressure support is received by the patient. | 03-13-2014 |

20140290664 | PATIENT INTERFACE DEVICE WITH NOSE BRIDGE ADJUSTMENT - A patient interface device includes a bladder assembly having a headgear bladder member, a nose bridge bladder member, and a connecting tube member provided between the headgear bladder member and the nose bridge bladder member. The headgear bladder member is in sealed fluid communication with the nose bridge bladder member through the connecting tube member, and is filled with a fluid medium. The bladder assembly is structured such that the nose bridge bladder member will be inflated as a pressure on the headgear bladder member increases and such that the nose bridge bladder member will be deflated as the pressure on headgear bladder member decreases. Inflation of the nose bridge bladder member causes the top of a cushion member to move toward the patient's nose bridge, and deflation of the nose bridge bladder member causes the top of the cushion member to move away from the patient's nose bridge. | 10-02-2014 |

20150083136 | GAS CARRYING HEADGEAR WITH POROUS BOUNDARY MEMBRANES - A respiratory interface device is provided. The respiratory interface device includes at least one elongated support member structured to contact a user. The support member has at least one conduit portion and at least one porous portion. The conduit portion is structured to allow the passage of gas therethrough. The conduit portion is structured to be in fluid communication with a pressure generating system and with the porous portion. The porous portion is structured to allow for axial passage of gas therethrough and for radial exhaust of gas therefrom. | 03-26-2015 |
