Patent number: 9772274Abstract: An improved optical flow cell adapted for use in a flow cytometer for differentiating formed bodies (e.g., blood cells) in liquid suspensions. Preferably manufactured by assembling, aligning, and optically joining at least two elements made from transparent material, the improved flow cell has a seamless internal flow channel of preferably non-circular cross-section in a cylindrical first element through which prepared samples can be metered and an independent second element having an external envelope suited to acquisition of optical parameters from formed bodies in such suspensions, the second element being conforming and alignable to the first element so that non-axisymmetric refractive effects on optical characterizing parameters of formed bodies passing through the flow channel in the first element may be minimized before the two elements are optically joined and fixed in working spatial relationship.Type: GrantFiled: March 14, 2014Date of Patent: September 26, 2017Assignee: Beckman Coulter, Inc.Inventors: Marshall Donnie Graham, William Gerry Graham, James P.

Patent number: 9625367Abstract: In flow cytometry, particles (2) can be distinguished between populations (8) by combining n-dimensional parameter data, which may be derived from signal data from a particle, to mathematically achieve numerical results representative of an alteration (48). An alteration may include a rotational alteration, a scaled alteration, or perhaps even a translational alteration.

Patent number: 9610583Abstract: An embodiment of a reagent container includes a bottle with a pipe to reduce the effects of reagent sloshing. The bottle has an elongated base and an opposed cover connected by side walls and an end wall. A flat platform surrounded by a raised rim lies in the base opposite an opening in the cover. A ribbed pipe frictionally fits within the bottle opening and may attach to the anchor region leaving vent passages around the pipe. The pipe includes an aperture adjacent to the anchor region and oriented toward the end wall so that sloshed fluid has only a small effect on the level of reagent in the pipe during transfers. A modified blow molding process produces the anchor region by extending a pin a predetermined distance into a mold while the molded material is still plastic.Type: GrantFiled: May 27, 2015Date of Patent: April 4, 2017Assignees: Beckman Coulter, Inc., DTIL Ireland Holdings Ltd.Inventors: Hiroyuki Onishi, Masato Kayahara, Hiroshi Suzuki, Ryusuke Furuya, Naoki Mukaiyama, Michael Cooney, Marcus O'Neill, Sean O'Mahony

Patent number: 9535083Abstract: In some embodiments of the invention, the central controller may comprise a processor and a computer readable medium coupled to the processor. The computer readable medium comprises code, executable by the processor to implement a method. The method comprises identifying, by the processor, a sample container or a sample container holder associated with the sample container, and then accessing, by the processor, a location database storing mapping data correlating sample containers or sample container holders with sample containers to test regions in the storage unit. The test regions store sample containers with samples that have been or are to be tested according to different tests. After accessing the database, the method continues by providing, by the processor, a proposal for storage of the sample container or the sample container holder associated with the sample container in the storage unit.Type: GrantFiled: December 16, 2013Date of Patent: January 3, 2017Assignee: Beckman Coulter, Inc.Inventor: Patrick Cohen

Patent number: RE46214Abstract: 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.Type: GrantFiled: February 9, 2006Date of Patent: November 22, 2016Assignee: Beckman Coulter, Inc.Inventors: Humayun Qureshi, Bernhard Spless, Robert A.
