A valve device suitable for detachably fixing to an access port and includes a fixation clip which has at least a first and second fixation member each of which have one or more rims each having a surface which veers in a direction towards the valve device. There is further provided a removing tool for removing the valve device from an access port. There is further provided a mounting tool for mounting a valve device in an access port. An assembly having a mounting tool and a valve device is also provided.

A dispensing system includes a hollow tube having an outer wall with an air vent formed in the outer wall. A valve including a flexible flap is disposed inside the tube. The flexible flap, normally biased into a retracted position, is moveable between an extended position for sealing the air vent and the retracted position for unsealing the air vent. A syringe connector interconnects a syringe with the proximal end of the hollow tube and defines a fluid flow path. A flowable viscous fluid is disposed within the syringe. When a syringe plunger is depressed, the flowable viscous fluid is expelled from the syringe and forced through the fluid flow path and into the proximal end of the hollow tube. When the flowable viscous fluid engages the flexible flap, the flexible flap is forced to move into a position that seals the air vent.

A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

A connector is provided comprising first and second hollow connector bodies, the connector having a first expanded position providing a first fluid flow path through the first hollow connector body, and a second collapsed position providing a second fluid flow path through the first and second hollow connector bodies.

In one aspect, a valve includes a valve body rotatable about a central axis of the valve body, an interior channel adjacent the valve body for permitting a fluid to flow through an axial opening of the interior channel, and a plug within the interior channel that is movable between a first axial position at the axial opening and a second axial position spaced apart from the axial opening. In the first axial position, the plug closes the axial opening to prevent the fluid from flowing through the axial opening in a first direction and to prevent the fluid from flowing through the axial opening in a second direction that is opposite to the first direction. In the second axial position, the plug permits the fluid to flow through the axial opening into the interior channel in the first direction.

The present disclosure provides a method and apparatus for draining. The apparatus includes a body, the body having a first compartment adjacent to a second compartment, the first compartment having an inlet port fluidly connected to an outlet port, the inlet port defining a needle seat within the first compartment, a first rod hole for operation with a second rod hole in the second compartment, and a plurality of venting holes, the second compartment having a plurality of spaced notches along. The apparatus further includes a setting rod, the setting rod having a shaft and a sealing head, the shaft sized to be slideably maintained in the first rod hole and the second rod hole, the sealing head slideably attached to an end of the shaft and sized to obstruct fluid flow from the inlet port at the needle seat.

An infusion device includes a housing with an interior chamber sized and configured to hold at least a flange and plunger of a syringe, a trigger held by the housing, and a lever in communication with the trigger and including an upwardly extending cam with a cam path having an upper end. The cam is in communication with the flange of the syringe. In response to actuation of the trigger to dispense fluid from the syringe, the upper end of the cam travels upward above the syringe and longitudinally toward a dispensing end of the syringe to linearly translate the plunger of the syringe in a first direction to dispense fluid from the syringe. To refill fluid into the syringe, the upper end of the cam travels downward and longitudinally away from the dispensing end of the syringe to linearly translate the plunger in a second direction to intake fluid.

Disclosed is a transfer device for use in reconstituting dry drugs and for diluting liquid drugs in drug containers. The transfer device includes a multi-port manifold and a connector suitable to be attached to a drug container, a first conduit to transfer a liquid entering an inlet port of the manifold through the connector and into the drug container, and a second conduit to transfer a gaseous fluid through the connector to an outlet port of the manifold. Also disclosed is a closed liquid transfer system which includes the transfer device, a tube connectable to the inlet port for transporting a liquid to the transfer device, a tube connectable to the outlet port for transporting the gaseous fluid away from the transfer device, and a gas collection container to collect the gaseous fluid in the gas transporting tube.

A valve device for a medical fluid line system includes a main body, the main body having a first fluid passage and a second fluid passage, each fluid passage of the first and second fluid passages extending between an inlet side and an outlet side of the main body. The main body has a first wall portion and a second wall portion which are each elastically displaceable, under an effect of fluid pressure, relative to a substantially dimensionally stable web portion of the main body. Each wall portion of the first and second wall portions is arranged on the web portion, forming one of the first and second fluid passages, in such a way that the first fluid passage is substantially uninfluenced by a fluid-pressure-induced deformation of the second wall portion, and the second fluid passage is substantially uninfluenced by a fluid-pressure-induced deformation of the first wall portion.

A sphygmomanometer device includes a piezoelectric pump, a valve, and a cuff. The valve includes a first valve housing, a diaphragm, and a second valve housing. The diaphragm is fixed to the second valve housing and first valve housing such that it is separated from a valve seat and the periphery of an opening portion in the diaphragm is in contact with a valve seat while providing a pressure thereto. Thus, the diaphragm defines a lower valve chamber communicating with a first vent hole, an upper valve chamber communicating with a second vent hole, a lower valve chamber communicating with a first vent hole, and an upper valve chamber communicating with the upper valve chamber, together with the second valve housing and first valve housing.
