US Patent:

8569713, Oct 29, 2013

Filed:

May 13, 2009

Appl. No.:

13/320216

Inventors:

John Henry Evers - Medway MA, US

Assignee:

Lantheus Medical Imaging, Inc. - North Billerica MA

International Classification:

G21G 4/04
G21G 4/08
G21G 4/06

US Classification:

250438, 250428, 250432 PD, 250432 R, 2505051, 2505061

Abstract:

A column assembly of a radionuclide generator includes a column that retains a parent radionuclide that spontaneouosly decays to a relatively short-lived daughter radionuclide. A fluid path extends from an inlet port to the column and then to an outlet port and allows daughter radionuclide to be eluted from the radionuclide generator for use. Improved retention of parent radionuclide in the column is accomplished by preventing fluid from entering the flow path in a liquid state, such as during sterilization. Proper column chemistry is also promoted by preventing excess moisture from coalescing in the column, which may promote a higher and/or more reliable yield of daughter radionuclide from a radionuclide generator.

US Patent:

Filed:

Jan 20, 1987

Appl. No.:

7/004703

Inventors:

John H. Evers - Bellingham MA

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

G21F 500

US Classification:

2505061

Abstract:

A receptacle for a carrying a vessel therein is provided with abutments that engage against the vessel itself or against a shield that receives the vessel to prevent relative motion of the vessel with respect to the receptacle as a torque is applied to the cap of the vessel.

US Patent:

Filed:

Oct 12, 1990

Appl. No.:

7/596273

Inventors:

John H. Evers - Medway MA

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

G21G 100
G21H 500

US Classification:

250432PD

Abstract:

A radionuclide generator of the type having a column with an inlet port and an outlet port, means for connecting the inlet port of the column to a source of eluant, and means for connecting the outlet port to an eluate collection vessel, further includes a plug removably mounted to the inlet connecting means to seal the same and a cover removably mounted to the outlet connecting means. The outlet cover has a vent therein whereby gases produced during the sterilization of the generator are vented.
