    Abstract: An infusion system includes a double action infusion pump. The pump includes a cylinder and a reciprocating piston received within the cylinder, the reciprocating piston separating a first pump chamber from a second pump chamber of the cylinder. A reciprocating motor is coupled with the reciprocating piston, and the first and second pump chambers alternate between filling and evacuating conditions with reciprocation of the reciprocating piston through operation of the reciprocating motor, and the speed of reciprocation is varied to provide a continuous output of fluid between the first and second pump chambers. A fluid source and a catheter are optionally coupled with the double action infusion pump. The catheter includes one or more infusion ports near a catheter distal portion, and the one or more infusion ports receive and expel the continuous output of fluid from the double action infusion pump.

    Abstract: In general, this disclosure relates to techniques for automatically supplying a pressurizing unit (e.g., syringe) that is used with a powered medical fluid injection device with fluid. An example method performed by the medical fluid injection device includes obtaining operational state information of the medical fluid injection device, wherein the operational state information includes information other than a fluid delivery amount for a subsequent injection procedure. The example method further includes using the operational state information to determine whether the powered medical fluid injection device permits a fluid replenishment operation for the pressurizing unit. If the fluid replenishment operation is permitted, the method further includes automatically supplying the pressurizing unit with an amount of medical fluid. If the device includes multiple pressurizing units, the device may initiate an automatic fluid replenishment procedure for one or more of the pressurizing units during operation.

  • Publication number: 20130303903
    Abstract: The preset invention provides a liquid injector in which, when an injection time period and an injection rate are entered as an injection condition, a condition image having a horizontal width corresponding to the injection time period and including the injection rate as text data is displayed in a condition screen with its vertical axis representing the injection rate and its horizontal axis representing the injection time period at a vertical position in association with the injection rate and a horizontal position in association with the injection time period. The operator easily understands instinctively the injection condition from the horizontal width and the position of the condition image, and since the condition image includes the injection rate as text data, the operator can check quickly the numerical values. Thus, the liquid injector can be provided which allows simple entry and review of the injection condition.

    Abstract: A jetless intravenous catheter for the delivery of a fluid into a peripheral vein of a subject includes an elongated body having proximal and distal ends. The body includes a wall defining an internal fluid passageway configured to receive fluid flowing in a longitudinal direction from the proximal end at a first axial velocity and a tip aperture at the distal end configured to allow fluid to exit therethrough. The body comprises at least one flow reducing feature configured to create a laminar-turbulent transitional flow associated with a fluid flowing in the longitudinal direction at the first axial velocity and configured to reduce the flow velocity of fluid exiting the tip to a second axial velocity that is less than the first axial velocity.

  • Publication number: 20130245439
    Abstract: A medical fluid injector system (450) is disclosed that may utilize one or more of flow rate determination logic (130), injection volume determination logic (132), display control logic (134), drive ram motion control logic (136), and pressure monitoring logic (138). The flow rate determination logic (130), injection volume determination logic (132), and display control logic (134) each may utilize a concentration input (172, 192, 202) to calculate flow rates, injection volumes, and generate multi-color graphics, respectively, for a simultaneous injection configuration. The drive ram motion control logic (136) may utilize both a target pressure and a monitored pressure to derive a velocity for advancing a drive ram. The pressure monitoring logic (138) may provide a monitored pressure value for the drive ram control logic (136), where this monitored pressure value may be derived from the input power being used to advance a drive ram and the drive ram velocity.

    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.
