Abstract: The system described comprises a respiratory therapy flow device, a respiratory circuit, and an exhalation valve. The device includes an exhalation pressure control port. The exhalation valve is removably engaged with the exhalation pressure control port and the respiratory circuit. The valve comprises a lid, a diaphragm, and a housing body. The housing body comprises a ramped lock configured to engage the respiratory therapy flow device at the exhalation pressure control port. Responsive to an engagement between the valve and the exhalation pressure control port, the lid forms a compression seal with the exhalation pressure control port, the diaphragm forms a compression seal with the lid, and the diaphragm is selectively controlled via gas pressure received through the exhalation pressure control port such that gas in the respiratory circuit flows to the ambient atmosphere during exhalation by the subject.

Abstract: The present disclosure pertains to an apparatus configured to facilitate monitoring of gas in a therapeutic gas delivery system with a catalytic sensor. The gas delivery system comprises a pressure generator having an inlet and an outlet, and a gas delivery flow path configured to communicate the gas between the pressure generator and a subject. The apparatus comprises a receiver body configured to receive the catalytic sensor such that the catalytic sensor removably couples with the receiver body, the receiver body located remotely from/outside the gas delivery flow path; a delivery port configured receive a portion of gas obtained from the gas delivery system that has passed through the pressure generator outlet and guide the received portion of gas toward the catalytic sensor; and a return port configured to exhaust the received portion of gas from the receiver body to the gas delivery system through the pressure generator inlet.

Abstract: Systems and methods for coupling a respiratory support circuit (5, 5a) to a pressure generator (140) include multiple flow paths 13,17) for corresponding modes of operation. A first flow path (13) for a first mode of operation couples fluidly between the pressure generator, through a control port (12) and a circuit port (14), to an exhalation limb (20) of a dual-limb configuration of a respiratory support circuit. A second flow path (17) for a second mode of operates couples fluidly between the pressure generator, through a control port (16) and a circuit port (18), an exhalation valve (21) of a single-limb configuration of the respiratory support circuit.

Abstract: A pressure support device such as a CPAP machine, is provided, which includes a housing, and a controller enclosed by the housing. The controller operates the CPAP machine independently or in combination with an accessory such as, for example and without limitation, a humidifier. A user interface is operably coupled to the controller and includes a primary display, a secondary display and a single control. The single control is operable in a first mode of operation to adjust operating parameters of the CPAP machine, and in a second mode of operation to adjust operating parameters of the humidifier. The secondary display preferably comprises a dead front, which is operational (e.g., without limitation, visible) only in the second mode of operation. A method of operating a pressure support device is also disclosed.

Abstract: An in-line humidifier is disposed along the passageway of a breathing system. The humidifier includes a humidification chamber having a fluid inlet, a fluid outlet, and a reservoir. The humidifier includes a liquid trap which includes a chamber, a fluid inlet in communication with the liquid trap chamber, and a fluid outlet in communication with the liquid trap chamber. The liquid trap is constructed and arranged to discourage liquid from back-flowing from the humidifier to a source of gas.

Abstract: A pressure support device (50) such as, such a CPAP machine (50), is provided, which includes a housing (51), and a controller (64) enclosed by the housing (51). The controller (64) operates the CPAP machine (50) independently or in combination with an accessory (70) such as, for example and without limitation, a humidifier (70). A user interface (66) is operably (74) coupled to the controller (64) and includes a primary display (72), a secondary display (74) and a single control (76). The single control (76) is operable in a first mode of operation to adjust operating parameters of the CPAP machine (50), and in a second mode of operation to adjust operating parameters of the humidifier (70). The secondary display (74) preferably comprises a dead front (74), which is operational (e.g., without limitation, visible) only in the second mode of operation. A method of operating a pressure support device (50) is also disclosed.

Abstract: A breathing system (1) includes a gas source (10) connected to a patient interface (80) via a passageway (90). An in-line humidifier (50) is disposed along the passageway. The humidifier includes a humidification chamber (400) having a fluid inlet (420), a fluid outlet (430), and a reservoir (410). The humidifier includes a liquid trap (200) comprising a chamber (210), a fluid inlet (220) in communication with the liquid trap chamber, and a fluid outlet (230) in communication with the liquid trap chamber. The fluid outlet of the liquid trap is in fluid communication with the fluid inlet of the humidification chamber. The liquid trap is constructed and arranged to discourage liquid from back-flowing from the humidifier to the source of gas. For example, a spill height defined by the liquid trap's fluid inlet is elevated relative to a low point of an interior of the liquid trap regardless of an orientation of the humidifier.
