An oral irrigator handle including a housing and a first fitting, the first fitting including a first fitting inlet in fluid communication with a handle inlet in fluid communication with a fluid source and a first fitting outlet in fluid communication with the first fitting inlet. The handle includes a seal positioned around the first fitting and between the first fitting inlet and the first fitting outlet. A second fitting includes a second fitting inlet in fluid communication with the first fitting outlet and a second fitting outlet in fluid communication with the second fitting inlet. A bottom portion of the second fitting seats on a portion of the first fitting so that the seal engages an interior surface of the second fitting, a flow passage is coupled to the second fitting and in fluid communication with the second fitting outlet.

A flow interrupter for gas flow delivered by a delivery conduit in a respiratory treatment system permits temporary interruption of flow in the conduit. Typically, the apparatus has a passage to conduct a breathable gas. The passage traverses through a flexible wall such as a stretchable sleeve. The flexible wall may include a first and second ends. A manipulator may be attached to the flexible wall. The flexible wall sleeve may be adapted to twistably collapse between the first and second ends so as to reduce the passage of the channel by operation of the manipulator. The flow interrupter may be formed with a swivel and operation of the sleeve may be implemented by rotation of the swivel. Sufficient rotation of such a swivel may form a vortex closure of material to close the channel. Release of the manipulator may then permit unwinding of the vortex closure, re-opening the channel.

The present teachings may generally include a sealing device disposed within a connector (e.g., a patient connector) at an end of catheter tubing, where the sealing device is structurally configured to form a releasable seal for the catheter tubing. That is, when unengaged with a contact portion of another connector or device, the sealing device may be disposed in a first position establishing the seal. Specifically, a channel disposed through a body of the sealing device may be obstructed when in the first position. However, through predetermined engagement with the contact portion of another connector or device, the sealing device may be moved (e.g., rotated) to a second position to establish a fluid pathway through the channel. And, when the predetermined engagement is removed, the sealing device may be structurally configured to automatically move back into the first position to reestablish the seal for the catheter tubing.

A fluid delivery line (FDL) for use in transporting a targeted temperature management (TTM) fluid between a TTM module and a thermal contact pad is disclosed. The FDL can include a bi-luminal fluid conduit and a bi-luminal proximal FDL connector. The two lumens of the proximal connector can be concentrically arranged. An authentication tag attached to the FDL can provide authentication data to a TTM module. A TTM system can include a connection adapter added to an existing TTM module where the adapter includes the electro-mechanical valves. An adapter controller operates the valves in accordance with obtained authentication data from the tag. Fluid connection systems can include valves that automatically open and close upon connection and disconnection. Fluid conduits and connectors can include concentrically arranged fluid lumens.

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.

An infusion set system, including a base and a fluid connector removably coupleable thereto is disclosed. The fluid connector includes a fluid path portion and at least one connector latch displaceably connected to the fluid path portion and displaceable to a latching position in which at least a portion of the connector latch extends into the fluid path portion, which includes a cannula extending from a top interior surface thereof, and a plurality of internal sidewalls corresponding to at least two of a plurality of flat side surfaces of at least one of a base section and a base latch, thereby facilitating connection between the base and the fluid connector in a plurality of discrete rotational connecting positions. When the fluid connector is locked to the base, the at least one connector latch engages a base latching portion of the base and restricts proximal displacement of the fluid connector.

A blower unit for use as part of an integrated blower/humidification system is described. The blower unit has an outer casing, which encloses and forms part of the blower unit, the casing including an air inlet vent. The blower unit further includes a humidifier compartment for receiving a humidifier unit with a separate gases inlet and outlet, the compartment having a heater base for heating the contents of the humidifier unit. The compartment also has a blower inlet port which aligns with the humidifier unit inlet in use, the blower providing a gases path through the casing between the inlet vent and the inlet port. The blower unit also includes a fan for providing a pressurised gases stream along the gases path, and a power supply unit for powering the fan. The gases path is routed over the power supply unit in order to provide a cooling air flow.

An infusion set, patch pump, or elements thereof, having an exemplary catheter (14) provided with one or more channels, grooves and coatings (24, 34, 44), configured and arranged to provide a degree of strength and flexibility. The catheter (14) can also have an exemplary flexible union with the hub (12) having at least one of a ball-and-socket joint (66, 68), a sliding plate (86), and a flexible bushing (106), and which is sealed to allow even further movement of the catheter (14) while preventing leakage of medication through the junction. In doing so, a number of benefits associated with the use of rigid materials in catheter construction can be provided while at the same time, benefits associated with the use of flexible materials in catheter construction and/or flexible engagement with the hub can also be provided.

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.

An arrangement for introducing a liquid into the body of a patient or for withdrawing a liquid from the body of a patient, including a first structural part carrying a cannula for positioning in the body of the patient, and a second structural part with a connection port for detachably coupling a conduit for supplying or withdrawing a liquid, wherein the first and second structural parts are connected, can be rotated relative to each another and in relative rotational positions form a channel for introducing a liquid from the conduit to the cannula or for withdrawing a liquid from the cannula to the conduit, and whereby movement of the conduit for coupling and uncoupling is transverse to the longitudinal axis of the cannula.
