Patent number: 9572947Abstract: 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.Type: GrantFiled: October 31, 2012Date of Patent: February 21, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jonathan Sayer Grashow, Lauren Patricia Chodkowski
