Abstract
A patient interface of the present invention includes a faceplate including a plurality of headgear attachment elements, a seal member operatively coupled to the faceplate; and an adjustment mechanism coupling the seal member to the faceplate. The adjustment mechanism controls the position of the seal member relative to the faceplate such that the seal member is moveable from a first position to a second position and is maintained in the second position during use of the patient interface after being moved to the second position.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A patient interface comprising:
