Abstract: Medical breathing tubes have a tubular body that defines a lumen extending between open terminal ends of the tubular body. An internal form is enclosed within the lumen and supportive of the tubular body. The internal form may be a coated encapsulated internal form where the coating secures the internal form to the tubular body. The internal form may provide for a series of alternative crests and troughs of the tubular body. A patient interface and/or a securement system may be attached to the tubular body.

Abstract: A user interface convertible between a nasal configuration and an oral configuration. The user interface has a nasal cannula and a mouthpiece. The nasal cannula has a body portion and at least one prong extending from the body portion, the prong being adapted to direct a flow of gas into a nare of a user's nose. The mouthpiece is adapted to engage the mouth of the patient and direct a flow of gas into a user's mouth. In the nasal configuration the prong of the nasal cannula is adapted to direct a flow of gases into a nare of the patient. In the oral configuration, the nasal cannula is engaged with the mouthpiece such that a gases flow is provided to at least the mouth of the user.

Abstract: Condensation or “rain-out” is a problem in breathing circuits and especially neonatal breathing circuits. The subject patent provides an improved breathing tube component for managing rain-out particularly in neonatal applications. In particular the breathing tube has a smooth inner bore, and an outer insulating layer containing stagnant gas and a heater wire.

Abstract: A component useable with one or more tube comprises a body engageable with one or more external surface recesses of the one or more tubes. The component has a pair of jaws extending from the body for gripping an item. The component is configured, such that, in use, in a first orientation of the body relative to the respective tube(s) recesses, the component is movable along a length of the tube(s); and, in a second orientation of the body relative to the respective tube(s) recesses, the component is resistive to movement along a length of the tube(s).

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: In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.

Abstract: Nasal cannulas for providing respiratory therapy to patients can have a curved prong section that has turbulation elements on the inside curve of the prong. A flow of breathing gas moving through the prong may incur less resistance and create less noise when flowing through such a prong due to the promotion of favorable flow dynamics.

Abstract: This invention relates to a patient interface and component parts which may be integrated or form a part of an assembled interface for use by a user. In various embodiments, the component parts may include: a component may be provided as a clip for supporting a gas supply tube to the interface; a buckle may be provided at an end of a headgear strap for releasable attachment to the interface; a manifold part of a patient interface may be attachable to the interface in a manner allowing for adjustment or re-orientation such that an associated gas supply conduit is re-routed to be to a left- or a right-side of the interface (or user); one or a pair of support side arms of the interface may be configured to be twisted or bent so as to more comfortably accommodate the shape of a user's face upon which they are to be located in use; parts of a manifold at the connection of a gas supply tube to the interface may be configured to be of a multi-part manifold assembly.

Abstract: The present disclosure relates to determining a corrected exhaled gas measurement during high flow respiratory therapy. Measuring exhaled gas concentration during high flow respiratory therapy is difficult and inaccurate due to a phenomenon known as flushing. The high flows delivered to the patient flush the dead space in the conducting airways, which causes a dilution effect that results in underestimated or overestimated exhaled gas measurement depending on the gas composition delivered by the high flow system. This can lead to incorrect clinical measurements and diagnoses. Various algorithms are disclosed herein to account for the dilution effect caused by flushing, allowing for the method of measuring gas concentrations to still be used accurately for clinical measurements.
