A dual lumen IV administration set includes a first lumen having an inner diameter of a first value. A second lumen is paired with the first lumen, and the second lumen has an inner diameter of a second value that is greater than the first value. A flow merger merges flow output from a distal end of the first lumen and flow output from a distal end of the second lumen to form a single flow output in an exit lumen. An injection port intersects the first lumen, thereby providing injection access to flow therethrough, prior to merging with the flow output of the second lumen.

Fluid dispensing device, having a pump connected to a reservoir and to a head. A piston (22) is connected to a piston rod (25) and provided with a push-button (26) to actuate the pump. A spring (27) brings the piston to the rest position after actuation. The body has a T-like connection (24), with a first branch connected to the metering chamber, a second branch connected to the reservoir and a third branch is connected to the head. A first valve (41) is provided in the second branch and a second valve (51) in the third branch, the valves are urged against the first and second respective valve seats (43, 53). The device has dose a adjustment (28, 29) cooperating with the piston rod and has a bush (29) coaxially around the piston rod movable to adjust the rest position of the piston.

An infusion pump is disclosed. The infusion pump comprises a chamber having a distal end and a proximal end, and a longitudinal axis between the proximal end and the distal end. A piston is arranged for reciprocating movement within the chamber and along the longitudinal axis. At least one outlet is arranged from the chamber and may comprise an outlet valve. At least one inlet is provided into the chamber. The outlet and the inlet are axially spaced apart along the longitudinal axis of the chamber. A method for operating the pump is also provided.

In some embodiments, a housing can define a reservoir. A lower cap can be coupled to the housing and define an outlet, and an upper cap can be coupled to the housing and can define an inlet. The upper cap can include an extending portion extending laterally a distance beyond an outermost extending portion of the lower cap relative to a central axis of the housing such that, when the lower cap and the extending portion of the upper cap contact a horizontal surface, the central axis of the housing is transverse to the surface and a sealing member is configured to sealingly engage a sealing surface of a valve seat prior to a liquid fluid level within a reservoir decreasing below a minimum threshold fluid level.

A drainage device includes a conduit extending from a bottom end toward a top end and a valve coupled to the conduit. The valve includes a first stop having an opening and an obstruction within the conduit. The obstruction, in a first configuration, may be spaced apart from the opening, enabling fluid to flow through the first stop and through the conduit. The obstruction, in a second configuration, may block the opening to prevent fluid flow through the first stop and through the conduit. The obstruction may move from the first configuration to the second configuration in response to (1) fluid pressure acting in a direction from the bottom end toward the top end of the conduit, or (2) when a fluid having a higher density than the obstruction is disposed within the valve.

A support device to support a catheter assembly may include a platform, which may include an upper surface and a bottom surface. The support device may include an extension element coupled to the upper surface of the platform. The extension element may include a distal end, which may include a first connector configured to couple to the catheter assembly, and a proximal end, which may include a second connector. The extension element may include a valve that may be movable between a first position and a second position. In response to the valve being moved to the first position, a fluid pathway extending through the cannula and the extension element may be open and straight. In response to the valve being moved to the second position, the fluid pathway may be closed. The support device may include a cannula, which may be swaged within the extension element.

A device and method for applying a pharmaceutical fluid comprising a hollow cylindrical body, which surrounds a channel that extends through the body from a proximal body end to a distal body end of the body, wherein an outer surface of the body has at least partially an external thread, and has a connecting element arranged at the proximal body end, via which a proximal channel end of the channel can be reversibly connected in terms of fluid conduction to a reservoir for the pharmaceutical fluid.

A ball valve for use in a respiration circuit proving for selective gas flow between at least two outlets of the ball valve and a respiration circuit including the ball valve.

Provided is a contrast medium injection system that allows a connector of a tube connected to a patient to be reliably locked and easily unlocked with a small force and kept clean in normal use.

The system includes a detachably attachable injection line kit, at least one fluid injection flow path and a first connector provided on a downstream end of the flow path. The kit includes at least one patient connection flow path and a second connector that is provided on an upstream end of the patient connection flow path and detachably attachable to and engageable with the first connector. The contrast medium injection system body has a first set position where the kit is set and a second set position where the first and second connectors are engaged more deeply than in the first set position.
