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: Nasal cannulas for providing respiratory therapy to patients can have a body, two prongs extending from the body, and a gases inlet on one side of the body. There can be a throttle or internal localized reduction in the cross-sectional area of a cavity defined by the internal walls of the cannula body in between the prongs. In at least some arrangements, the throttle can partially or substantially fully equalize flow between the prongs of the cannula.

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: A connector is described that may be configured to connect between a first tube and a second tube. The connector has an internal component and an external component. The external component has a first end and a second end. The first end has an external taper and an internal coupling face that may be configured to interact with the first tube and the second end may be configured to interact with the second tube. The internal component may be configured to rotate independently to the external component. The external component has a gripping region to aid the user in disconnection of the connector. An attachment mechanism may attach the second tube to the internal component.

Abstract: Nasal cannula assemblies for providing respiratory therapy to patients are provided. A nasal cannula assembly can include a cannula, an optional manifold, 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 warming device (30) for warming the lens portion (2) of an optical instrument (I), such as a laparoscope, to a temperature above ambient to prevent lens fogging comprising: a double walled cylindrical tube (3) having an intemal wall (3b), and an external wall (3a), an upper surface and an open distal portion (7) with a central cavity (4) therebetween; a protrusion (9) extending from said upper surface, sized and shaped to receive the lens portion; a circular cap (5) sized to attach to said distal portion of said double walled cylindrical tube; and, a heating element (15) enclosed within said central cavity and thermally coupled to said insulation layer.

Abstract: The invention relates to systems for securing a tube (e.g. feeding tube) and/or a patient interface or a dermal patch to a user. One embodiment comprises a holder, an interface side of the holder attachable to the patient interface or the dermal patch for securing a feeding tube to the patient interface or the patch, the holder comprising at least a first channel or recess for receiving the feeding tube to couple the feeding tube to the patient interface. Another embodiment comprises a patient interface itself comprising a backing for positioning on a patient's face, a dermal patch having a patient side and an interface side, the patient side of the patch attachable to the user, the patch comprising at least a first flap portion attachable to the tube for affixing the tube to the patch, a two-part releasable connection arrangement for releasably securing the patient interface to the patch.

Abstract: This invention relates to a headgear component as a part of a headgear. The component comprising a backstrap, a first ear loop extending from one end of the backstrap, the first ear loop following a path defining a first ear opening, and a second ear loop extending from another end of the backstrap, the second ear loop following a path defining a second ear opening. A first pair of connection zones is on the first ear loop, each connection zone spaced an equal distance from the backstrap and spaced from each other, and a second pair of connection zones on the second ear loop, each connection zone spaced an equal distance apart from the backstrap and spaced from each other. A connection zone of the first pair and a connection zone of the second pair are on a first side of the backstrap, and a connection zone of the first pair and a connection zone of the second pair are on a second (other) side of the backstrap, wherein the headgear component is substantially of a symmetrical shape.

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. In an embodiment, the connector is 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. In an embodiment, the connector assembly is 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: 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 medical breathing tubes comprising a tubular body, the body defining a lumen extending between open terminal ends of the body and an internal form enclosed within the lumen and supportive of the tubular body. The internal form may be of a coated encapsulated internal form, the coating securing the internal form to the tubular body. The internal form may also or separately provide for a series of alternative crests and troughs (e.g. corrugations) of the tubular body. Patient interfaces (such as masks or nasal cannula) can be connected to such tubing. A system for securing patient interfaces in an operational position may also be utilised.

Abstract: This invention relates to a headgear comprising a semi-rigid frame engageable with the head of a user and a releasable connection system for releasable connection with a user interface, wherein the frame extends generally about a rear region of a user's head, generally about an upper region of a user's head, and generally about an ear or both ears of a user.
