Abstract: A humidifier for an airway pressure support system, includes a base, a number of side walls extending from the base, and a top wall provided opposite the base, wherein the base, the number of side walls, and the top wall are made from an elastomeric material and at least partially define an internal chamber for receiving and holding a liquid. The humidifier also includes a plurality of support structures provided on or within the humidifier, each support structure extending along at least the number of side walls, wherein the humidifier is structured to collapse from an initial, expanded condition to a collapsed condition when a compressive force is applied to the top wall in the initial, expanded condition and to automatically return to the initial, expanded condition when the force is removed.

Abstract: A humidifier (68, 68?, 100, 100?) for an airway pressure support system (50), includes a base (70, 102), a number of side walls (76, 78, 104) extending from the base, and a top wall (80, 106) provided opposite the base, wherein the base, the number of side walls, and the top wall are made form an elastomeric material and at least partially define an internal chamber (82) for receiving and holding a liquid. The humidifier also includes a plurality of support structures (88, 88?, 112, 114, 118, 120) provided on or within the humidifier, each support structure extending along at least the number of side walls, wherein the humidifier is structured to collapse from an initial, expanded condition to a collapsed condition when a compressive force is applied to the top wall in the initial, expanded condition and to automatically return to the initial, expanded condition when the force is removed.

Abstract: An adapter apparatus (24, 80) for a respiratory therapy system (2) having a pressure generating device (4) and an electrical tube assembly (22) coupled to a patient interface device (8) includes a first end having a first port member (66, 94) structured to be fluidly coupled to the electrical tube assembly, a second end having a second port member (70, 88) structured to receive a flow of breathing gas generated by the pressure generating device, the adapter apparatus being structured to deliver the flow of breathing gas to the electrical tube assembly through the first port member, and a wire assembly having a first electrical connector (76, 104) structured to be electrically coupled to the electrical tube assembly and a second electrical connector structured to be electrically coupled to the pressure generating device in order to provide an electrical connection between the electrical tube assembly and the pressure generating device.

Abstract: A connection assembly for rotateably and electrically coupling an accessory to a main device includes a housing portion, a rotatable port assembly, and a wire assembly. An end of the port assembly is coupled to the accessory. The port assembly includes an electrical connector member having a first connector end electrically coupled to the accessory. The wire assembly has an electrical wire member having a first end electrically coupled to a second connector end of the electrical connector member and a second end electrically coupled to a power supply. The wire member is spooled around the port assembly and encased in a chamber defined between the housing portion and the port assembly. Rotation of the port assembly in opposite directions causes the electrical wire member to spool more and less tightly around the port assembly without causing pinching or tangling of wires.

Abstract: A patient interface device (8, 8?) for delivering a flow of breathing gas to an airway of a patient includes a grooved adjustment mechanism (20, 58, 78) having a main body (22, 60) formed from an elastic material, the main body having an outer surface having a plurality of convolutions (80) provided therein. Each convolution including a groove (24, 62, 84), and each convolution has a stiffness associated therewith. The stiffnesses associated with the convolutions increase from a first side of the main body to a second side of the main body.

Abstract: A system for delivering a flow of breathing gas to a patient that includes a main delivery conduit coupled to a gas source, and a rotary coupling device coupled to the main delivery conduit and having a first member and a second member, the first member defining a first channel and a second channel through the first member, the second member defining a third channel and a fourth channel through the second member. The first channel is in communication with the third channel to define a main channel having a main path, and the second channel is in communication with the fourth channel to define a secondary channel separate from the main channel and having a secondary path. The first member and the second member are structured to freely ro tate relative to one another in a manner that separately maintains the main path and the secondary path.
