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.

Exhalation port

A medical circuit incorporates a medical tube and a connector. The medical circuit 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 members 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.

Medical tubes and connectors for gases delivery systems

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. The connector can alternatively or additionally include a coaxial wye-piece that includes an inspiratory branch, an expiratory branch, and a patient end. The tip of the inspiratory branch that is internal to the coaxial wye-piece may have a lip and a narrowed diameter, features which obstruct or reduce condensate from entering the inspiratory branch and the inspiratory conduit regardless of the coaxial wye-piece orientation or position.
