Patent number: 9314565Abstract: Injector systems which include a syringe and a powered injector to inject a fluid into a patient are described. The powered injector includes a drive member, an energy source, at least one sensor for detecting energy from the energy source, and at least one contact member axially movable in the injector and in communication with the sensor. The syringe includes at least one indicator positioned at a predetermined position, such as on a rear surface of an attachment flange, which may transmit or reflect energy from the energy source to the sensor. The contact member may contact and be moved by the indicator when the syringe is attached to the powered injector, so that the energy detected by the sensor may be determined by the position of the indicator. The position of the indicator thereby provides information about the syringe configuration.Type: GrantFiled: March 17, 2013Date of Patent: April 19, 2016Assignee: Bayer HealthCare LLCInventors: Michael A. Spohn, Joelle A. Rudnick, Thomas P. Joyce, Adam J. Hahn, Michael J. Masters, William J. Nolan, Jason A. Zaperach, Joseph B. Havrilla

Patent number: 8439876Abstract: Injector systems including a syringe for use with a powered injector having a drive membre to inject a fluid into a patient having a first indicator positioned on the syringe at a predetermined position are described. The position of the first indicator may be associated with information about the syringe configuration. The first indicator can, for example, be positioned on a rear surface of an attachment flange of the syringe. The injector system includes sensors each having on and off states, and a shutter mechanism configured to place sensors in the on or off states. The state of each of the sensors provides a digital code corresponding to information on the syringe configuration.Type: GrantFiled: April 6, 2009Date of Patent: May 14, 2013Assignee: Medrad, Inc.Inventors: Michael A.

Publication number: 20090247867Abstract: A syringe for use with a powered injector to inject a fluid into a patient includes at least a first indicator positioned on the syringe at a predetermined axial position. The distance between a rearward surface of the first indicator and a predetermined position on the powered injector provides information about the syringe configuration. The first indicator can, for example, be a rear surface of the attachment flange. An injector system includes a powered injector having a drive member and at least one sensor for detecting energy. The injector system also includes a syringe having at least a first indicator positioned on the syringe at a predetermined axial position. The energy detected by the sensor is determined by the axial position of the indicator when the syringe is attached to the powered injector. The axial position of the indicator thereby provides information about the syringe configuration.Type: ApplicationFiled: April 6, 2009Publication date: October 1, 2009Applicant: MEDRAD, INC.Inventors: Michael A.

Patent number: 6972001Abstract: A fluid delivery system for delivery of an injection fluid to a patient generally includes a first pump system, a second pump system, a patient interface in removable fluid connection with the first and second pump systems, and a fluid path in fluid connection between the first and second pump systems and the patient interface. The fluid path preferably includes a housing member defining a first inlet, a second inlet and an outlet. The first and second pump systems are placed in fluid connection with the respective first and second inlets of the housing member and the patient interface is placed in removable fluid connection with the outlet of the housing member. A first check valve is in fluid connection between an outlet of the first pump system and the first inlet of the housing member, and a second check valve is in fluid connection between an outlet of the second pump system and the second inlet of the housing member.Type: GrantFiled: March 1, 2004Date of Patent: December 6, 2005Assignee: Medrad, Inc.Inventors: Michael F.

Patent number: 6808513Abstract: A front-loading syringe, which comprises a movable plunger for injecting liquid contrast media, is mountable on a front wall of an injector housing having a pressure jacket, by a first quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An injection end of the syringe may include loop-shaped reinforcing handle portions.Type: GrantFiled: June 10, 2002Date of Patent: October 26, 2004Assignee: Medrad, Inc.Inventors: David M.

Patent number: 6733478Abstract: A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs, which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background.Type: GrantFiled: November 4, 2002Date of Patent: May 11, 2004Assignee: Medrad, Inc.Inventors: David M.
