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: 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.

Patent number: 8808253Abstract: The fluid injector system includes a source of injection fluid, a pump device, and a fluid path set in fluid connection with the source of injection fluid and the pump device. The fluid path set includes a drip chamber including an elongated body having a raised projection from substantially a top end to substantially a bottom end, the elongated body configured to receive and contain the injection fluid. A fluid level sensing mechanism is operably associated with a fluid control device, and includes a support for the drip chamber body, wherein the support is adapted such that the raised projection is in operational contact with a fluid level sensor associated with the support. The fluid level sensing mechanism is operable to transmit ultrasonic or light energy through the raised projection to be sensed by the fluid level sensor for sensing the injection fluid level in the drip chamber.Type: GrantFiled: April 2, 2012Date of Patent: August 19, 2014Assignee: Bayer Medical Care Inc.Inventors: Michael A.

Patent number: 7556619Abstract: The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.Type: GrantFiled: April 16, 2004Date of Patent: July 7, 2009Assignee: MEDRAD, Inc.Inventors: Michael A.
