Patient interface device including a pneumatically adjusting forehead support

摘要

A patient interface device (8) includes a patient sealing assembly (12) adapted to communicate a flow of breathing gas within an airway of a patient, the patient sealing assembly including a cushion (14), a frame member (16) coupled to the cushion, and an adjustable forehead support assembly (26) coupled to the frame member. The adjustable forehead support assembly includes a forehead cushion (30) and an inflatable and deflatable bladder (48) coupled to the forehead cushion, wherein inflation and deflation of the bladder causes the distal end (24) of the frame member to move relative to the forehead cushion in a manner wherein a pressure applied to a bridge of a nose of the patient by the cushion is adjusted.

1. A patient interface device, comprising:
a patient sealing assembly adapted to communicate a flow of breathing gas within an airway of a patient, the patient sealing assembly including a cushion and a frame member coupled to the cushion; an adjustable forehead support assembly operatively coupled to a distal end of the frame member, the adjustable forehead support assembly including a forehead cushion, and a selectively inflatable and deflatable bladder coupled to the forehead cushion; a pump structured to selectively pump a medium into the bladder in order to inflate the bladder, wherein the pump is provided within a housing member provided at the distal end of the frame member and includes a bulb member fluidly coupled to the bladder; and at least one actuating member provided on an outside of the housing member and structured to apply a squeezing force to the bulb member to cause the medium trapped in the bulb member to be provided to the bladder, and wherein inflation and deflation of the bladder causes the distal end of the frame member to move relative to the forehead cushion in a manner wherein a pressure applied to a bridge of a nose of the patient by the cushion is adjusted.
