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.

Abstract: A mask 100 configured to substantially surround an opening of a patient's airway. The mask has a mask body 101 comprising a filter 103 configured to filter a fluid from a patient facing side of the mask to a non-patient facing side 105 of the mask, wherein the non-patient facing side faces an ambient environment AE. The mask has an interfacing feature 121 configured to, in use, interface with a patient interface 10100, 10100? provided on the patient 10020.

Abstract: Several embodiments of exhalation ports for use respiratory systems are described. Some of the embodiments provide an elongate body defining a lumen through which gases may flow. A plurality of tapered openings is arranged on a portion of the elongate body and configured to vent gases. A shroud extends from the elongate body and surrounds one or more of the plurality of tapered openings. The exhalation port is arranged to removably connect in-line with a circuit for delivering gases to a patient.

Abstract: An apparatus or kit for a respiratory support system for delivering humidified gas to a user or patient. The apparatus comprising a humidifier chamber in pneumatic communication with a gases source, an inspiratory conduit in pneumatic communication with the humidifier chamber downstream of the humidifier chamber, a filter that is in pneumatic communication with the inspiratory conduit downstream of the inspiratory conduit, and a patient interface for delivering humidified gas to a user or patient, wherein the patient interface is in pneumatic communication with the filter downstream of the filter, or is configured to be placed in pneumatic communication with the filter downstream of the filter.

Abstract: A patient interface is disclosed which is comfortable for the user to wear and includes at least in part a moisture permeable or breathable area in the body of the patient interface. In another embodiment the patient interface is a strapless mask that is moulded to fit the contours of a user's face and maximise the mask-to-skin seal. An adhesive material is bonded to the mask cushion and is stamped in place to form substantially the same shape as the cushion such that it fits the facial contours of the user.

Abstract: This invention relates to a connector for a component of a medical breathing circuit. The connector comprises an inner body and an outer body. The inner body and the outer body being separate components. The inner body having a retention mechanism configured to engage another connector, and an outer body configured to at least partly surround the inner body, the outer body having a tube engagement mechanism.

Abstract: A medical circuit comprising a medical tube and a connector transports gases to and/or from a patient via a patient interface. The connector has a plurality of rigid components at least partially surrounded by an overmold. The medical tube has a first elongate member and a second elongate member. The first elongate member is substantially hollow. A vent can be coupled to the first elongate member such that it maintains gaseous communication with the lumen. The vent may provide a pathway between the lumen and the atmosphere, such that gases may move into and/or out of the lumen during cleaning. The vent may also provide a barrier to liquid and/or substance ingress into the first elongate member during cleaning of the medical circuit. The medical circuit can be reusable.

Abstract: A molded member containing a thermoplastic material and a substrate, wherein at least a portion of the substrate is coupled to the thermoplastic material via a silicon-containing linker, and a respiratory apparatus containing the molded member are disclosed. A respiratory apparatus containing a molded member, wherein the molded member contains a thermosetting material and a substrate, and wherein at least a portion of the substrate is coupled to the thermosetting material via a silicon-containing linker is also disclosed.

Abstract: Connectors for respiratory assistance systems are disclosed that are configured to at least decrease the proportion of condensate that drains into an inspiratory conduit. The connectors include a setup that causes the portion of a wye-piece connected to an expiratory conduit to be positioned below the portion of the wye-piece connected to the inspiratory conduit. The connector can alternatively, or additionally, include a wye-piece that includes a ball attached to the wye-piece adjacent the inspiratory conduit port such that when the ball is connected to a medical stand, the expiratory conduit port is positioned below the inspiratory conduit port. The connector can alternatively or additionally include a circuit hanger that includes a cradles for both conduits and a ball attached to the circuit hanger adjacent the inspiratory conduit cradle such that when the ball is connected to a medical stand, the expiratory conduit cradle is positioned below the inspiratory conduit cradle.
