Method And System For Sample Aliquot Storage

US Patent:
6793888, Sep 21, 2004
Filed:
Jul 18, 2001
Appl. No.:
09/908169
Inventors:
Humayun Qureshi - Eden Prairie MN
Bernhard Spiess - Minnetonka MN
Robert A. Weiss - Victoria MN
Peter G. Werness - Carver MN
Brian D. Wilson - Chaska MN
Ronald C. Laska - Minnetonka MN
Assignee:
Beckman Coulter, Inc. - Fullerton CA
International Classification:
G01N 100
US Classification:
422 63, 422 64, 422 67, 436 43
Abstract:
A method and system of sample aliquot storage for automated immunochemistry or chemistry instruments are provided. The method and system provide a sample aliquot storage unit having a sample storage wheel for storing sample vessels containing sample aliquots in a chilled enclosed environment, which are accessible by both a sample pipettor of a sample aliquoting station and a pick-and-place gripper. The pick-and-place gripper transports the sample vessels containing sample aliquots to multiple independent reagent pipetting stations respectively for sample aspiration of subsequent assay, and thereafter transports the sample vessels containing remaining sample aliquots back to the sample storage wheel to be stored in the chilled environment for reflex testing. When all the tests are completed, the pick-and-place gripper transports the sample vessels to a waste storage area.

Method And System For Automated Immunochemistry Analysis

US Patent:
6825041, Nov 30, 2004
Filed:
Mar 16, 2001
Appl. No.:
09/815088
Inventors:
Humayun Qureshi - Eden Prairie MN
Glenn A. Davis - Minnetonka MN
Mark J. Kittock - Eden Prairie MN
Armer J. Willenbring - Minnetonka MN
Brian D. Wilson - Chaska MN
Peter G. Werness - Carver MN
Assignee:
Beckman Coulter, Inc. - Fullerton CA
International Classification:
G01N 3500
US Classification:
436 43, 422 63, 422 64, 422 65, 422 66, 422 67, 436 47, 436 50
Abstract:
A method and system for automated immunochemistry or chemistry analysis are provided. The method and system provide a sample aliquoting section, a reagent pipetting section having a plurality of independent reagent pipetting stations, each operating on a cycle of a first period of time, and an incubate and wash and read section operating on a cycle of a second period of time to match the throughput of the system, where the quotient of the first period of time divided by the second period of time is a whole number, and the number of the independent reagent pipetting stations being equal to the whole number. The respective cycles of the independent reagent pipetting stations are staggered apart by the second time period, such that at least one of the multiple independent pipetting stations is available for working with the incubate and wash and read section at each operating cycle of the second period of time.

Fluid-Moving Device With A Clearance Seal

US Patent:
6843481, Jan 18, 2005
Filed:
Oct 10, 2000
Appl. No.:
09/685307
Inventors:
Mark J. Kittock - Eden Prairie MN,
Humayun Qureshi - Eden Prairie MN,
Assignee:
Beckman Coulter, Inc. - Fullerton CA
International Classification:
F16J 1544
US Classification:
277411, 277447
Abstract:
A clearance seal assembly is disclosed. The assembly comprises a stationary member defining a first side, a second side and an opening connecting the first and second side; a moving member moveably disposed through the opening; and a sealing member circumferentially disposed between the stationary member and the moving member. The sealing member has a fluid-tight relationship with the stationary member. The sealing member and the moving member define a continuous and uniform gap having a size that allows the fluid to fill the gap but prevents the fluid from flowing through the gap from the first side to the second side of the opening under an operating pressure differential between the first and the second side. In a preferred embodiment, both the sealing member and the moving member are made of a ceramic material. The sealing assembly may also include a static seal disposed between the stationary member and the sealing to allow a variable clearance therebetween while maintaining the fluid-tight relationship between the sealing member and the stationary member.

Assignee:
Beckman Coulter, Inc. - Fullerton CA
International Classification:
B32B 5/02
US Classification:
422 63, 294 271, 294106, 294116, 294 85, 436 43, 81 331
Abstract:
A method and system for picking and placing vessels are provided. The system includes a gripper assembly mounted on a positioning mechanism. The gripper assembly includes a cylinder, a plurality of flexible gripping members extending from the cylinder in a spaced-apart relationship for receiving therebetween a vessel and holding it by friction, a piston slideably inserted inside the cylinder, and a plunger connected to and movable with the piston and extending between the gripping members for engaging the vessel. The method includes the steps of positioning the gripper assembly, picking up and transferring a vessel, and placing, seating and releasing the vessel. The contents of the vessel may also be mixed simultaneously during the transferring of the vessel.

Method Of Metering A Fluid Using A Multi-Mode Differential Fluid Displacement Pump

US Patent:
5366904, Nov 22, 1994
Filed:
Apr 21, 1992
Appl. No.:
7/871491
Inventors:
Humayun Qureshi - Wayland MA
Stanley M. Liffmann - Andover MA
John D. Czaban - Beverly MA
Assignee:
DRD Diluter Corporation - Danvers MA
International Classification:
G01N 100
G01N 3348
US Classification:
436180
Abstract:
A measured amount of a first fluid is metered into a measured amount of a second fluid by a method where a fluid is confined within a first chamber and a plunger of predetermined volume is mechanically moved into the chamber to displace a first measured amount of fluid after which a second plunger is mechanically moved into a defined volume of the chamber to displace a second volume of fluid therefrom different from the first volume whereupon the first and second volumes can be mixed in predetermined proportions.
