Publication number: 20220032029Abstract: A single-use connector configured to be removably connected to a reusable connector includes a hollow, tubular housing having an open proximal side opposite a distal side along a longitudinal length of the housing and at least one guard member connected to the tubular housing. The at least one guard member is configured to transition between an open position, in which the single-use connector can be connected to the reusable connector, and a closed position in which the guard member prevents the single-use connector from being connected to the reusable connector. Disconnecting the single-use connector from the reusable connector causes the at least one guard member to transition from the open position to the closed position. A single-use disposable set (SUDS) including a single-use connector and at least use guard member for preventing reconnection of the connector to a reusable connector or fluid port is also disclosed.Type: ApplicationFiled: December 18, 2019Publication date: February 3, 2022Inventors: CHRISTOPHER LAZZARA, MICHAEL SWANTNER, DANIEL MOORE, III, RONALD HELLER, BARRY TUCKER

Patent number: 11141535Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.Type: GrantFiled: August 28, 2018Date of Patent: October 12, 2021Assignee: BAYER HEALTHCARE LLCInventors: Arthur Uber, III, Chelsea Marsh, William Barone, Michael McDermott, Timothy Newing, Michael Spohn, Vince Delbrugge, Ralph Schriver, Kevin Cowan, Barry Tucker, Ronald Heller, David Griffiths, Matthew Schrauder

The selector valve body is adapted to place the flow passage in fluid communication with one of the first outlet port, the second outlet port, and a shut-off position. Further, the selector valve body includes a sealing arrangement having an elastomeric core disposed within a thin-walled valve stem which comprises a thin cylindrical sidewall in direct contact with the valve bore. When the elastomeric core and the valve stem are subjected to internal fluid pressure, the thin cylindrical sidewall of the valve stem expands outward to increase a sealing force between an outer diameter of the valve stem and the valve bore.Type: GrantFiled: September 20, 2012Date of Patent: July 11, 2017Assignee: BAYER HEALTHCARE LLCInventors: Christopher D.

Publication number: 20140228762Abstract: A fluid pump device is operable by a drive and actuating system. The fluid pump device includes a pump manifold, a plurality of pump cylinders, a plunger reciprocally operable in each of the pump cylinders, and at least one inlet selector valve. The pump cylinders may extend proximally from the pump manifold and are in selective fluid communication with the pump manifold via, for example, respective inlet and outlet check valves. The plungers are reciprocally operable within the pump cylinders and are independently and reciprocally operable by respective piston linear actuators provided in the drive and actuating system. The inlet selector valve is used to establish selective fluid communication between one or more fluid source containers and the pump manifold to control fluid flow into the pump manifold. The inlet selector valve may be located laterally outboard of the pump cylinders and extend generally parallel to the pump cylinders.Type: ApplicationFiled: September 20, 2012Publication date: August 14, 2014Inventors: Christopher D.
