PATIENT INTERFACE DEVICE WITH NOSE BRIDGE ADJUSTMENT

摘要

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.

主权项

1. A patient interface device, comprising:
a patient sealing assembly including a cushion member; a headgear assembly coupled to the patient sealing assembly, the headgear assembly including a strap; and a bladder assembly comprising:
a headgear bladder member coupled to the strap,a nose bridge bladder member positioned adjacent a top portion of the cushion, anda connecting tube member provided between the headgear bladder member and the nose bridge bladder member, wherein the headgear bladder member is in sealed fluid communication with the nose bridge bladder member through the connecting tube member, the bladder assembly being filled with a fluid medium, wherein the bladder assembly is structured such that the nose bridge bladder member will be inflated as a pressure on the headgear bladder member increases in response to a force applied thereto by the strap increasing and such that the nose bridge bladder member will be deflated as the pressure on headgear bladder member decreases in response to the force applied thereto by the strap decreasing, and wherein inflation of the nose bridge bladder member causes the top of the cushion member to move in a first direction and deflation of the nose bridge bladder member causes the top of the cushion member to in a second direction opposite the first direction.
