Patent number: 8353879Abstract: A medical fluid injector, replaceable syringe, and coupling mechanism to engage the syringe plunger to the plunger drive ram of the injector are provided wherein coupling involves a cam cleat-like mechanism, thereby allowing for cooperative movement between the plunger drive ram and syringe plunger. The coupling mechanism of the plunger drive ram is provided with first and second movable members, each having toothed, arcuate surfaces, while the coupling mechanism of the syringe plunger is provided with a knurled cavity. Disengagement of the coupling mechanism is facilitated by translational movement of a face plate located on the forward end of the injector housing.Type: GrantFiled: October 15, 2007Date of Patent: January 15, 2013Assignee: Mallinckrodt LLCInventors: James H. Goethel, Robert G. Bergen

Method and apparatus for injecting fluid into animals and disposable front loadable syringe therefor
Patent number: 7081104Abstract: An animal fluid injector, replaceable syringe and method of replacement of the syringe in the injector are provided in which the syringe is loadable and unloadable into and from the injector through the open front end of a pressure jacket of the injector, thereby permitting replacement without retraction of the syringe plunger drive or disconnection of the injection tubing. The syringe is provided with a pressure restraining front end, such as an integral or removable cap with structure such as threads that lock the syringe to the front end of the jacket by mating with threads on the jacket. A mechanism in the injector, which includes, for example, a key on cam ring operated by a lever with one hand of an operator, interacts with structure such asymmetrically spaced notches on the back end of the syringe to, for example, rotate the syringe and simultaneously translate or rotate a coupling on the syringe plunger into and out of engagement with the plunger drive in the injector.Type: GrantFiled: December 8, 2003Date of Patent: July 25, 2006Assignee: Liebel-Flarsheim CompanyInventors: Charles Neer, Frank M.

Patent number: 5855568Abstract: A syringe discharge end having a rotatable tubular connector member for engaging a luer connector on medical tubing. The syringe discharge end and the connector have mating threads which are used to affix the connector to the syringe discharge end. Once affixed, the connector is may freely rotate relative to the syringe, while being prevented from axial movement. On its distal end, the connector includes internal threads for engaging external threads on a standard luer connector of medical tubing. To engage the connector to tubing, the connector is rotated relative to the tubing and the syringe to draw the tubing onto the syringe discharge end.Type: GrantFiled: November 22, 1996Date of Patent: January 5, 1999Assignee: Liebel-Flarsheim CompanyInventors: Dane J.

Patent number: 5851184Abstract: An electrocardiograph controlled injection continues until a programmed amount of contrast media has been injected, rather than until a predetermined number of heart cycles has been experienced. As a result, if injections are terminated early due to a PVC in the patient's heart rhythm, the injector will continue to attempt injections for an indefinite number of subsequent heart cycles, until the programmed volume of contrast media has been injected, rather than terminating operation after a set number of injections.Type: GrantFiled: November 22, 1996Date of Patent: December 22, 1998Assignee: Liebel-Florsheim CompanyInventor: James H.

Patent number: 5456670Abstract: An animal fluid injector is provided with a syringe guide, preferably in the form of a pressure jacket, having an open front end through which a replaceable disposable syringe is loadable into and unloadable from, thereby permitting replacement without retraction of the syringe plunger drive or disconnection of the injection tubing. The injector is provided with structure, preferably in the form of thread sections, which mates with cooperating structure on the syringe, to connect and lock the syringe to the injector, preferably by rotational motion of, preferably, less than a full turn, of for example, 90.degree.. In the illustrated embodiment, the structure is at the front end of the guide or at the front periphery of a jacket to connect to threads on a pressure restraining front end of the syringe.Type: GrantFiled: March 3, 1994Date of Patent: October 10, 1995Assignee: Liebel-Flarsheim CompanyInventors: Charles Neer, Frank M.
