Patent number: 10751465Abstract: A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes an automatic refill procedure for a fluid injector system comprising a fluid injector and an operably engaged syringe. The procedure includes the step of determining, using an electronic control device operably controlling the fluid injector system, whether a fluid injection procedure involving the syringe is impending. If the electronic control device determines that the fluid injection procedure is not impending, such that the automatic refill will not interfere with the fluid injection procedure, an automatic refill of the syringe is initiated.Type: GrantFiled: October 21, 2016Date of Patent: August 25, 2020Assignee: BAYER HEALTHCARE LLCInventors: Michael A. Riley, Ralph H. Schriver, William D. Barlow, Thomas P. Joyce, Andreas Maihoefer

Patent number: 10029220Abstract: A fluid path set includes a first fluid line having a proximal end fluidly connectable to a source of a first fluid and a second fluid line having a proximal end fluidly connectable to a source of a second fluid. A flow mixing device is in fluid communication with distal ends of the first and second fluid lines. The flow mixing device includes a housing, a first fluid port provided for receiving the first fluid, and a second fluid port for receiving the second fluid. A mixing chamber is disposed within the housing and is in fluid communication with the first and second fluid ports. A third fluid port in fluid communication with the mixing chamber for discharging a mixed solution of the first and second fluids. A turbulent flow inducing member is disposed within the mixing chamber for promoting turbulent mixing of the first and second fluids.Type: GrantFiled: January 27, 2017Date of Patent: July 24, 2018Assignee: BAYER HEALTHCARE LLCInventors: Ralph H.

Patent number: 8945051Abstract: A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes a powered injector, a pressure jacket support, a syringe pressure jacket, and a syringe. The pressure jacket support includes a front plate and a rear plate. The rear plate is connected to the injector and the front plate is spaced from the rear plate and defines a slot. The syringe pressure jacket has a proximal end pivotally connected to the rear plate so that a distal end of the pressure jacket pivots relative to the front plate. The syringe has a syringe body with a distally extending discharge conduit. With the syringe disposed in a barrel of the pressure jacket, pivotal movement of the pressure jacket results in the distal end thereof pivoting toward the front plate to place the discharge conduit within the slot in the front plate.Type: GrantFiled: July 20, 2010Date of Patent: February 3, 2015Assignee: Bayer Medical Care Inc.Inventors: Ralph H. Schriver, Jerry A. Stokes, Michael Riley, Michael Spohn, Patrick B. Campbell, James A. Dedig, William D. Barlow, Andreas Maihoefer, Thomas P. Joyce
