Abstract: An elongated flexible conduit (4) includes an flow element (24) having a first elongated wall segment (32) and a second elongated wall segment (44) that are connected together at their sides to form a wall (28) that is continuous in a circumferential direction perpendicular to the direction of elongation (8). The flow element is movable between a first configuration and a second configuration (68), with the first configuration being an expanded configuration, and with the second configuration being a collapsed configuration. The flow element can be moved from its expanded configuration to its collapsed configuration, such as for purposes of packing during traveling, and can then be moved from its collapsed configuration back to its expanded configuration in any of a variety of fashions in order to return the flow element to a condition in which it can carry a flow of breathing gas from a CPAP machine (12) to a CPAP mask (16).

Abstract: A patient interface device (8) includes a patient sealing assembly (12) including a cushion (14) and a frame member (16), and an adjustable forehead support assembly (26) provided at the distal end (24) of the frame member. The assembly includes an adjustment mechanism (28) coupled to a forehead cushion (30), the adjustment mechanism including a housing (32), a forehead cushion support member (52) having a base portion (58) and an elongated post member (60) extending from the base portion and received within the housing, and a locking member (54, 56) structured to be selectively coupled to the elongated post member. In the locked condition, the locking member engages the elongated post member and prevents the elongated post member from moving relative to the housing, and in the unlocked condition the locking member does not engage the elongated post member such that the elongated post member and the housing are freely linearly movable with respect to one another.
