Patent number: 6063052Abstract: The present invention provides a number of pumping systems and injection systems particularly useful for injecting a liquid medium into a patient. In general, the pumping systems comprise a removable pumping unit. The removable pumping unit includes means for pressurizing the liquid medium via the rotational displacement of the liquid medium. The present invention also provides a pumping system comprising a pumping unit for pressurizing the liquid medium and a feedback-controlled drive means in connection with the pumping unit for providing a controlled powered drive to the pumping unit. The pumping system further comprises a flow meter for measuring the flow rate of the pressurized liquid medium exiting the pumping system and control means in communicative connection with the drive means for providing a control signal to control the powered drive provided to the pumping unit.Type: GrantFiled: October 6, 1998Date of Patent: May 16, 2000Assignee: Medrad, Inc.Inventors: Arthur E.

Patent number: 5954668Abstract: A microwave antenna senses the temperature of tissue into which a fluid is to be injected. The fluid is injected by a needle or other vascular entry device connected to a fluid injector by a connector tube. The fluid temperature is measured by a temperature sensor attached to the connector tube. An alarm processor determines whether an extravasation occurs by comparing a temperature discrimination function derived from tissue temperature taken at different times with a calculated threshold value. The threshold value is calculated from the tissue temperature and the fluid temperature. The threshold value is recalculated and updated continuously during the fluid injection.Type: GrantFiled: June 14, 1996Date of Patent: September 21, 1999Assignee: Medrad, Inc.Inventors: Arthur E. Uber, III, David M. Griffiths

Patent number: 5145163Abstract: A film sheet load magazine is adapted to hold a stack of superimposed films with at least central portions of the films in a curved configuration and leading ends of the films adjacent a film separator mechanism. The curvature of the films is such that they retain themselves in desired positions in the magazine independent of the orientation of the films with respect to gravity. When a top cover of the magazine is opened, floating primary feed rollers are raised by spring-biasing assemblies to facilitate loading of the films under the rollers, and when the top cover is subsequently closed, the rollers are moved into feeding engagement with an innermost film, and the films are held in position by leaf biasing springs. A cleaning mechanism removes contaminants from the primary feed rollers, which feed each film to secondary feed rollers driven at a faster speed than the primary feed rollers.Type: GrantFiled: November 24, 1989Date of Patent: September 8, 1992Assignee: Medrad, Inc.Inventors: Kevin P. Cowan, Stanley R. Lewandowski, David M. Reilly, Arthur E. Uber, III

Patent number: RE35979Abstract: An angiographic injector has an injector portion which includes a rotating turret for housing two angiographic syringes in readiness for injection. The injector further employs a driving mechanism for connecting with and controlling the movement of a syringe plunger once one of the syringes is in place for injection. Through the use of guide means on each syringe and corresponding alignment means on a pressure jacket, the syringe is alignably and securely mounted within the pressure jacket on the rotating turret. Each syringe plunger is releasably connected to the driving mechanism for an injection operation, and released from the driving mechanism when the injection operation has been completed, such that the driving mechanism can be withdrawn from the syringe relative to the plunger without drawing body fluid of a patient into the syringe. Various types of plunger release mechanisms for this purpose are disclosed.The questions raised in reexamination request No. 90/003,918 filed Aug.Type: GrantFiled: December 10, 1991Date of Patent: December 1, 1998Assignee: MTFP, Inc.Inventors: David M.
