Appl. No.:

09/353521

Inventors:

James R. Small - Beavercreek OH
Frank M. Fago - Mason OH
Gary S. Wagner - Taylor Mill KY
Mitchell A. Smith - Cincinnati OH
Joseph B. Tyson - Silverton OH

Assignee:

Mallinckrodt Inc. - St. Louis MO

International Classification:

A61M 3100

US Classification:

604500, 604 82

Abstract:

A system to provide a specified volume of a medical fluid from a bulk source to a dose and/or delivery container for injection into a patient. The fluid path between the bulk container and the delivery container is physically separated at a connecting site before fluid is injected from the delivery container into the patient. The bulk container may be a bag or bottle, and the delivery container may be a syringe or bag. A bag delivery container may be contained in a pressurizeable chamber and fluid may be delivered by providing pressure to a membrane in the chamber contacting a wall of the bag. The system may be automated.

Appl. No.:

09/676143

Inventors:

Frank M. Fago - Mason OH

Assignee:

Mallinckrodt Inc. - St. Louis MO

International Classification:

A61M 5178

US Classification:

604181, 604122

Abstract:

A plunger is provided for a syringe that includes a pressure relief mechanism that exhausts any fluid trapped in the chamber between sealing flanges carried by the plunger when the plunger is advanced to dispense fluid from the syringe. The contact pressure between the barrel-contacting surface of the rearmost sealing flange nearest the access opening of the syringe barrel is weakened relative to the contact pressure provided by the barrel-contacting surface of the sealing flange that isolates the fluid within the barrel. The contact pressure of the rearmost sealing flange may be lessened by either reducing its radial diameter relative to the radial diameter of the other sealing flange, removing an underlying portion of the plunger, or configuring the rearmost sealing flange as deflectable sealing lip.

International Classification:

A61M 5315

US Classification:

604218, 604131, 604152

Abstract:

Various sealing structures are used in a front-loading injector, for preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. For example, a sealing gasket may be incorporated into the front face of the injector housing, for mating to the rearward circular edge of the cylindrical body of a syringe. Alternatively, sealing and locking functions may be performed by a single structure on the rearward end of the syringe. Further, leakage may be prevented by including a non-planar sealing flange on the syringe, positioned on the syringe forward of the locking structure, or by a two-piece structure, including a syringe and a separate leakage stopping washer for surrounding the syringe to halt the flow of fluid along the exterior of the syringe. (As part of this aspect, or as an independent feature, the syringe may include an annularly discontinuous flange forward of the locking structure, for providing mechanical support for the syringe against the injector. ) Alternatively, an iris-like structure may be incorporated into the front surface of the injector, for closing about the syringe upon insertion of the syringe into the injector.

Assignee:

Liebel Flarsheim Company - Cincinnati OH

International Classification:

A61M 100

US Classification:

604152, 604228

Abstract:

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 without retraction of the syringe plunger drive or disconnection of the injection tubing. 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 jaws of the plunger drive in the injector.

International Classification:

A61M 3700

US Classification:

604150

Abstract:

A hand-held remote for a medical fluid injector includes a syringe and a conduit which may be coupled to a pressure transducer on a control circuit of the injector. Movement of a plunger within a syringe body on the syringe creates a pressure which is sensed by the pressure transducer and the control circuit responds to the sensed pressure by causing fluid to be ejected from, or drawn into, a syringe mounted to the injector. The pressure developed by the remote provides tactile feedback to an operator for improved control over injections.
