摘要： A conduit connector assembly is provided for a respiratory therapy apparatus and configured to connect a patient interface to a gas delivery conduit. The assembly comprises: a conduit comprising a first flow port configured to be connected to the patient interface, and a second flow port configured to be connected to the gas delivery conduit, and a supplementary flow port; and a first valve port configured to be closed or opened by a valve flap. The conduit and the valve flap selectively provide an inspiratory flow path from the second flow port of the conduit to the first flow port of the conduit; and an expiratory flow path from the first flow port of the conduit to the supplementary flow port via the first valve port. A supplementary gas flow path is provided between the first and/or second flow ports and the supplementary flow port via a supplementary valve port.

摘要： A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

摘要： A patient interface comprises an opening for receiving a flow of gas from a conduit and an adaptable connector system for connecting at least two different types of conduit with the opening. The adaptable connector is permanently mounted with the patient interface so it cannot be lost and is able to swing into alignment with the opening, thereby providing a different connection end to be compatible with a second or further type of conduit connection end.

摘要： Systems and methods for non-invasive ventilation are provided. The systems may include a gas source that provides breathing gases to a patient through one or more of a primary flow path (PFP) and a flushing flow path (FFP). The system may include a control assembly configured to open and restrict gas flow through the PFP. When the PFP is open, a significant portion of the gas flows through the PFP while the remaining gas flows through the FFP. When the PFP is restricted, a significant portion of the gas flows through the FFP. Increased flow through the FFP may have a high velocity (especially relative to the flow through the PFP). Gas delivered through the FFP may be used to flush dead space. One or both flow paths may contribute to inspiratory positive airway pressure (IPAP), expiratory positive airway pressure (EPAP), and/or positive end expiratory pressure (PEEP).

摘要： A respiratory mask includes a housing and a cushion or seal that seals on a user's face in use. An upper portion of the seal that is disposed on a user's nasal bridge in use can roll toward and/or over the outer surface of the housing to form a rolling bridge feature that adjusts to different nose sizes. As the rolling bridge rolls, an apex of the seal moves away from the user's face to adjust to larger nose sizes. The apex does not move downward and can move upward relative to a location of the apex in a neutral position of the seal.
