ERGONOMIC AND ADJUSTABLE RESPIRATORY MASK ASSEMBLY WITH HEADGEAR ASSEMBLY

摘要

A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a main body and a side frame member provided on each lateral side of the main body. Each side frame member includes an integrally formed first connector portion. A headgear assembly is removably attachable to the frame. The headgear assembly has a second connector portion adapted to be removably coupled with the first connector portion provided on the frame. The second connector portion is manually movable to a releasing position to detach the headgear assembly from the frame. The headgear assembly is rotationally adjustable with respect to the frame.
