摘要： A nasal interface has a first nasal delivery element and second nasal delivery element, each configured to seal with a respective naris of a patient. A gases manifold comprises a gases inlet for delivery of respiratory gases to the gases manifold. The first nasal delivery element and second nasal delivery element are in fluid communication with the gases inlet via the gases manifold. The first nasal delivery element is proximal to, and the second nasal delivery element is distal from, the gases inlet. The nasal interface comprises a bypass restriction to provide a pressure drop through the nasal interface between the first nasal delivery element and second nasal delivery element when gases are delivered from the gases inlet to the first nasal delivery element and second nasal delivery element such that pressure at the first nasal delivery element is higher than pressure at the second nasal delivery element.

摘要： A respiratory therapy accessory comprises a body configured to be coupled to a support. The respiratory therapy accessory comprises at least one retaining member extending from the body. The retaining member is configured to retain a respiratory therapy component. In some examples, the respiratory therapy accessory comprises three retaining members. The three retaining members may be structurally dissimilar and extend from the body in different directions. The body may be configured to attach to the support by translation and rotation of the respiratory therapy accessory as a whole. The body may be configured to slide or rotate relative to the support. The respiratory therapy accessory may be used to facilitate transitioning a patient from one form of respiratory therapy to another, which involves changing at least the patient interface assembly used by the patient.

摘要： Various implementations of the present disclosure are directed to systems and methods for characterizing a conduit coupled to a respiratory therapy device in a respiratory therapy system. The method includes generating a first airflow from the respiratory therapy device to the conduit by operating a motor of the respiratory therapy device at a first revolutions per minute. The method further includes receiving a first airflow parameter data associated with the first airflow, wherein the first airflow parameter data has a first pair of two distinct airflow parameter values. The method further includes determining a first relationship between the first airflow parameter data and the conduit, and characterizing the conduit based on the first relationship.

摘要： A connector is provided for coupling with an invasive patient interface for providing respiratory support to a patient. The connector comprises a connector body having: (i) an inlet port couplable with a flow source providing a flow of respiratory gas; (ii) a gases exit port; and (iii) a device port couplable with the invasive patient interface. The connector also has a lumen having a first end and a second end. The connector body defines a gas flow path between the inlet port and both the device port and the lumen first end and the lumen second end is disposed outside the device port. The lumen provides improved CO2 clearance. Some embodiments provide for gas sampling and/or variable expiratory resistance.

摘要： This invention relates to a vent structure for a respiratory therapy system. In one form the vent structure comprises a vent housing. The vent housing may define a flow path for a flow of air being vented from the respiratory therapy system, a vent inlet configured to allow the flow of air to enter the flow path, and a vent outlet configured to allow the flow of air to exit the flow path into the surrounding ambient air. The vent housing may be configured so that the flow path comprises a curved turning region in which the flow path changes direction by at least 90°. The vent housing may comprise an inner path surface on an inner side of the flow path and an outer path surface on an outer side of the flow path. The width of the flow path at the turning region and at a region downstream of the turning region may be at least substantially 0.85mm. An opening angle between the inner path surface of the vent housing at the vent outlet and the outer path surface of the vent housing at the vent outlet may be substantially 7° or less.
