US Patent:

6355024, Mar 12, 2002

Filed:

Jul 14, 1999

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.

International Classification:

A61M 3700

US Classification:

604131

Abstract:

A contrast medium injector for injecting a patient with contrast medium for a CT scan is programmed to provide an injection protocol that is a representation of an ideally defined exponential curve with an initial injection rate decaying at an exponential rate. This has been found to produce a uniform vascular enhancement for the scanning of a patients blood vessels. The particular exponential decay coefficient which has been found to be optimal is directly proportional to the cardiac output divided by the patients weight and is approximated at 0. 01 for a typical human.

Assignee:

Mallinckrodt Inc. - Hazelwood MO

International Classification:

A61M 5/00

US Classification:

600432

Abstract:

A contrast media injection system includes detects the absolute position of the syringe ram using a non-contact sensor. A series of magnets and Hall-Effect sensors may be used or an opto-reflective system. Illuminated knobs that are connected to the drive mechanism for the syringe ram rotate with the drive and provide visual feedback on operation through the illumination. Analog Hall-Effect sensors are used to determine the presence or absence of magnets that identify the type of faceplate being used. The faceplates include control electronics, connected to the powerhead through connectors, which may be interchangeably used by the two faceplates. The faceplate electronics include detectors for automatically detecting the capacity of pre-filled syringes. Additional features include using historical data to provide optimum pressure limit values during an injection protocol, a removable memory device for storing and transferring information such as injection protocols and injector statistics, and password protection of such protocols.
