A threaded fluidic fitting may include a fluid passage, at least one fluid port, a threaded fitting portion, an engageable body portion, and an electro-fluidic leak detection element. The fluid passage extends from the fluid port of the threaded fluidic fitting. The threaded fitting portion comprises a helical thread, extends from a leak detection face of the engageable body portion, and is configured to rotate with the engageable body portion to enhance a fluidically sealed engagement of one of the fluid ports with a complementary fluidic component. The electro-fluidic leak detection element is positioned on the leak detection face of the engageable body portion or on a drip edge portion of a face extending from the leak detection face. A fluid handling system may include a plurality of threaded fluidic fittings and a leak detecting computing hub in communication with the plurality of threaded fluidic fittings.

A connector for connecting a pressure sensing catheter to charger is provided. The connector can include a first engagement portion engageable with a charger engagement portion of the charger to displace a pressure transmission medium in the charger engagement portion to charge one or more balloons of the pressure sensing catheter. The connector can have a handle that includes a tab terminating in an end surface engageable with an engagement surface of the charger when the first engagement portion engages with the charger engagement portion. The connector includes a distal abutment portion that engages with a portion of the charger engagement portion to provide an audible or tactile feedback, so as to prevent inadvertent overcharging of the balloons.

A charger for charging a pressure sensing catheter is provided. The charger can include a plurality of charging ports for receiving a portion of the proximal section of the pressure sensing catheter. The charging port may include an engagement portion for engaging with the portion of the proximal section of the pressure sensing catheter such that when the engagement portion engages with the proximal section of the pressure sensing catheter, the engagement portion is fluidly coupled to the catheter lumen and the pressure transmission medium from the engagement portion is displaced from the engagement portion to charge the one or more balloons of the pressure sensing catheter. The charger can include a cover for covering the engagement portion. The charger can include flutes defined on a surface of each charging port to permit a predetermined volume of the pressure transmission medium to be displaced from each charging port.

Breathing tube assemblies for use with a respiratory therapy device, such as a continuous positive airway pressure (CPAP) device, includes an elbow that permits adjustment of a position of the breathing tube assembly relative to the respiratory therapy device. In some arrangements, the breathing tube assembly includes a breathing tube and a swivel elbow. The breathing tube is rotationally fixed relative to the respiratory therapy device and the swivel elbow rotatable relative to the breathing tube. In other arrangements, the breathing tube assembly includes an elbow that can be coupled to the respiratory therapy device in one of several possible positions.

A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

A connector for connecting a pressure sensing catheter to charger is provided. The connector can include a first engagement portion engageable with a charger engagement portion of the charger to displace a pressure transmission medium in the charger engagement portion to charge one or more balloons of the pressure sensing catheter. The connector can have a handle that includes a tab terminating in an end surface engageable with an engagement surface of the charger when the first engagement portion engages with the charger engagement portion. The connector includes a distal abutment portion that engages with a portion of the charger engagement portion to provide an audible or tactile feedback, so as to prevent inadvertent overcharging of the balloons.

A catheter manufacturing method includes the step of providing a hollow cylindrical part of a catheter, having a longitudinal axis, to be bonded to a given part along respective edge surfaces of the hollow cylindrical and the given parts. One or more undercut structures that are disposed circumferentially with respect to the longitudinal axis and also generally parallel to the longitudinal axis, the undercut structures having a radial orientation with respect to the longitudinal axis, are formed at least in the edge surface of the hollow cylindrical part. The hollow cylindrical part and the given part are connected using the undercut structures.

A device to inhibit entanglement of catheter cables comprises a slip ring or a combined slip ring and fluid rotary joint. The device can include a servomechanism configured to power rotation of at least one of the slip ring and the fluid rotary joint. A detangling device for a cable plug configured to connect to a catheter handle comprises an outer cylinder configured to rotate relative to an inner cylinder while electrical connections between the inner and outer cylinders remain intact. A free rotary irrigation channel for a catheter handle inhibits entanglement of irrigation tubing.

A catheter control system the system can include a control unit having a first connection port. The control unit can have a first visual indicator associated with the first connection port. The system can also include a first catheter interface connector connected to the first connection port of the control unit. The first catheter interface connector can have a first visual indicator corresponding to the first visual indicator on the control unit. The first visual indicator on the first catheter interface connector can be to be active to indicate that the first catheter interface connector is connected to the first connection port on the control unit.

A circuit connector for a humidification system, the system comprising a base unit configured to be engaged by a humidification chamber. The circuit connector comprises an inlet to fluidly connect to an outlet of the humidification chamber to receive humidified gases therefrom, an outlet to sealably connect to or integral with a conduit for directing the humidified gases to a user, and an electrical terminal for electrically coupling the circuit connector to an electrical terminal associated with the base unit. The circuit connector may be releasably and lockably connectable to the outlet of the humidification chamber and/or orientation features may control orientation of component parts of the system as they are assembled.
