Abstract: A flow generator for use in respiratory therapy can be constructed with a housing. A support fixation arrangement can be fixed to the housing. The support fixation arrangement can have a tab having an aperture that may be fitted over a hook extending from a support structure. The tab can be fixed to the housing such that it is manually liftable or pivotable about a plane.

Abstract: 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.

Abstract: A humidification system can include a heater base, a chamber, and a breathing circuit. The heater base includes a heater plate positioned in a recessed region, and a heat conductive portion of the chamber is configured to contact the heater plate. The heater base includes a guard configured to control movement of the chamber into and out of the recessed region. The guard includes an anti-racking mechanism. The chamber includes an inlet port, an outlet port. A downward extension extends into the chamber from the inlet port, and a baffle is disposed at a lower end of the downward extension. A component of the breathing circuit can include a conduit hanging end cap for shipping and storage. The end cap can include a hanging component to allow the breathing circuit component to be hung from a medical stand. The system can detect when breathing circuits are connected in reverse.

Abstract: This invention relates to connectors to be provided into fluid communication or engagement either directly with, or via a component to be associated with, a terminal end of a breathing conduit. In at least one embodiment, the connector comprises a body having a first end and a second end, and an internal lumen for the passage of gas between the ends. The first end engageable with a terminal end of a conduit or a component to be associated therewith. The second end engageable with another connector. An internal surface of the body at the second end comprises internal connection features for connection with another connector to be received internally therein. An external surface of the body comprises one or more external alignment feature(s) for aligning the connector or another connection into an aligned orientation for connection therebetween.

Abstract: A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

Abstract: Nasal cannula assemblies for providing respiratory therapy to patients are provided. A nasal cannula assembly can include a cannula, an optional manifold which may be removable, a gas supply tube, and a securement mechanism. Securement mechanisms can include headgear straps, cheek pads, or an adhesive nose strip. A nasal cannula assembly can also include a lanyard, lanyard clip, and/or lanyard connector to help support the weight of a main gas delivery conduit.

Abstract: A connector for use in a respiratory system. The connector can connect a first respiratory system component such as a filter to a second respiratory system component. The connector has a body defining a bore for receipt of a complementary connector component. The bore has a terminal end that provides an entry into the bore for the complementary connector component. The connector comprises at least one internal retaining feature, at least one internal alignment feature, and/or at least one external alignment feature.
