  • Patent number: 9498570
    Abstract: A bladder syringe for a fluid delivery system includes a cylindrical body, a cap-bladder assembly, a plunger element disposed in the cylindrical body, and a mounting assembly to secure the cap-bladder assembly to the cylindrical body. The cylindrical body has a distal end and a proximal end and defines a throughbore. The cap-bladder assembly is adapted for connection to the distal end of the cylindrical body, and includes a cap body and a bladder. The cap body defines an interior cavity and a distal discharge conduit and is adapted to engage the distal end of the cylindrical body. A disc-shaped bladder is disposed within the interior cavity and typically includes a central membrane portion. The plunger element is disposed in the throughbore of the cylindrical body and is vented to enable evacuation of the space between the plunger element and the cap-bladder assembly in the cylindrical body.

  • Patent number: 9486573
    Abstract: A fluid delivery system includes a pressurizing mechanism. The pressurizing mechanism includes: a substantially cylindrical body having a movable member positioned therein that divides the body into a first chamber and a second chamber; a plunger rod connected to a first side of the movable member and extending through a substantially closed first end of the body; and an elongated member connected to a second side of the movable member and extending through a substantially closed second end of the body. The plunger rod configured to operatively engage a fluid container. Fluid is dispensed from the fluid container by forming a vacuum within at least the first chamber by moving the movable member toward the second end of the body, allowing atmospheric pressure to enter the second chamber, and actuating the pressurizing mechanism to cause the moving member to move towards the first end of the body.

  • Patent number: 9480797
    Abstract: A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engagable with the piston regardless of a rotational orientation of the piston relative to the plunger.

  • Patent number: 9408981
    Abstract: Adjustable volume syringes and systems are disclosed. An adjustable volume syringe includes a delivery syringe barrel, a reservoir syringe barrel positioned at least partially within the delivery syringe barrel, and a reservoir plunger positioned at least partially within the reservoir syringe barrel. The delivery syringe barrel is configured to contain a first amount of a fluid. The reservoir syringe barrel is configured to contain a second amount of the fluid. A system includes the adjustable volume syringe, a dispensing module in communication with the syringe, and a processor in communication with the dispensing module. The processor may be configured to determine an administration amount of the fluid in the adjustable volume syringe, and transmit signals causing the dispensing module to adjust the volume of fluid in the syringe to the administration amount and deliver the administration amount by moving the reservoir syringe barrel with respect to the delivery syringe barrel.

  • Publication number: 20160151570
    Abstract: A syringe interface between a piston and plunger is provided. The syringe interface includes a piston configured to be driven by an injector and a syringe. The syringe includes: a syringe barrel having a proximal end and a distal end; and a plunger having a proximal end, a distal end, and a sidewall extending therebetween. The plunger is slidably inserted in the syringe barrel such that the sidewall of the plunger forms a moveable seal against an inner surface of the syringe barrel. The piston is configured to form a removable suction engagement with the plunger for advancing or retracting the plunger through the syringe barrel as the piston is driven by the injector. A method for filling a syringe including a suction interface between a piston and plunger, as well as a filling station including a vacuum source, such as a vacuum pump, are also provided.
