Patent number: 8911685Abstract: Disclosed is an automated analyzer intended for qualitative/quantitative analysis of blood, urine, and other biological samples, and including a reagent disk for mounting a plurality of reagent containers thereon, wherein any errors in liquid-level measurement due to oscillation of a reagent liquid surface during rotation of the reagent disk are minimized, even when reagent containers of a large capacity are mounted. If a predetermined constant cycle time is defined as one unit, the reagent disk with reagent containers mounted thereon is transported to a liquid-level detection position using at least two units when a liquid level of a reagent is measured.Type: GrantFiled: February 3, 2010Date of Patent: December 16, 2014Assignee: Hitachi High-Technologies CorporationInventors: Atsushi Watanabe, Shigeki Matsubara, Teruhiro Yamano

Patent number: 8580196Abstract: When a problematic reagent is identified while operating an automatic analyzer, it is required to have a plurality of screens displayed, and it is difficult for inexperienced operators to identify a problematic position of a reagent. With the present invention, control information for reagents and a calibrator required for analysis with an automatic analyzer are displayed concurrently, so that all necessary information can be referred to one screen. In the automatic analyzer according to the present invention, screen switching as required in the conventional technology is not necessary, and improved operability and visibility are provided.Type: GrantFiled: August 16, 2007Date of Patent: November 12, 2013Assignees: Hitachi High-Technologies Corporation, Roche Diagnostics Operations, Inc.Inventors: Yasunao Awata, Kazuhiro Shimada, Yoshimitsu Takagi, Toshihide Orihashi, Shigeki Matsubara, Werner Döppen, Dietmar Kappelhoff

Patent number: 8475740Abstract: A liquid dispensing apparatus is provided which makes it possible to correctly and easily detect a dispensing operation judgment failure with high accuracy without particularly using a complicated detection mechanism or means. The liquid dispensing apparatus includes a nozzle which sucks a solution in a cassette and dispenses the sucked solution into another cassette; and a cassette holder which holds the another cassette, and the nozzle is used as a first electrode and the cassette holder as a second electrode. Further, the liquid dispensing apparatus has measurement means for measuring a capacitance between the first and second electrodes during a solution dispensing operation.Type: GrantFiled: May 14, 2008Date of Patent: July 2, 2013Assignee: Hitachi High-Technologies CorporationInventors: Atsushi Watanabe, Shigeki Matsubara, Takuya Yamaguchi, Masaaki Odakura

Publication number: 20110256022Abstract: An automatic analyzer is provided that can promptly process a request for additional test items for a sample being analyzed or an error that has occurred in the sample. The automatic analyzer has functions of outputting measurements of a sample analyzed, determining whether or not re-analyzing is necessary, and performing the re-analyzing. To achieve these functions, the automatic analyzer includes a buffer area for standby until analysis is completed and measurements are outputted. Each of analysis units includes a pair of buffer units that can randomly access the buffer area. The automatic analyzer further includes a position disposed near the buffer area, at which a sample can be unloaded and reloaded. A rack that is mounted with the sample in question and that stands by within the buffer area is unloaded onto the unloading position by a command to unload issued by an operator operating an operation section. Operations required for the sample are performed from above the unloaded rack.Type: ApplicationFiled: December 4, 2009Publication date: October 20, 2011Inventors: Masashi Akutsu, Shigeki Matsubara, Yoshimitsu Takagi, Hitoshi Tokieda

Publication number: 20110090066Abstract: An automatic analyzer restartable within a short time includes at least one of quality control information and calibration information stored into an analyzer processing unit. A reagent management unit reads out information from a reagent vessel ID tag affixed to a reagent vessel inside a reagent accommodation unit containing the reagent, and writes information onto the reagent vessel ID tag. The analyzer processing unit uses the reagent management unit to write the quality control information or the calibration information onto the reagent vessel ID tag.Type: ApplicationFiled: April 21, 2009Publication date: April 21, 2011Applicant: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Takuya Yamaguchi, Shigeki Matsubara

Publication number: 20110020949Abstract: In the field of automatic analyzers, as items to be analyzed are increase, various reagents differing in such properties as liquid viscosity and contact angle are being used more frequently, and this trend is expected to continue. Also, reagents now take various forms (e.g., a concentrated reagent to be diluted by the water of an automatic analyzer), and so does dilution water. Such being the case, the invention provides an automatic analyzer capable of sufficient stirring regardless of items to be analyzed. To sufficiently stir a substance to which a reagent has been added, the automatic analyzer is designed to alter stirring conditions after a given amount of time has passed since the addition of that reagent.Type: ApplicationFiled: May 1, 2009Publication date: January 27, 2011Applicant: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Chie Sugiyama, Shigeki Matsubara

Publication number: 20080206100Abstract: The automatic analyzer uses a sample pipetted into a sample vessel to perform analysis, the sample vessel being repeatedly cleaned and used. In order to prevent contamination of the sample vessel, which is caused by the measurement of general biologically-derived samples, from influencing the analysis, the automatic analyzer uses a specified sample vessel to measure a standard solution so that the calibration of each analysis item is carried out. The automatic analyzer does not use the sample vessel in question for analysis of other biologically-derived samples.Type: ApplicationFiled: February 26, 2008Publication date: August 28, 2008Inventor: Shigeki Matsubara

Patent number: 7384601Abstract: In an automatic analyzer, necessary setup works are displayed prior to analysis operation. The present invention can realize an automatic analyzer which can be used by an inexperienced operator to execute all necessary setup works. A maintenance button, data erase button, reagent status button, reagent prime button, calibration button and QC button are displayed on a system viewing screen displayed on an operation part. The display colors of the maintenance button or the like are changed (for example, the display color is changed to red, yellow or the like) in response to the status of the automatic analyzer in order to recognize necessary setup works prior to analysis operation for an operator.Type: GrantFiled: June 26, 2003Date of Patent: June 10, 2008Assignee: Hitachi High-Technologies CorporationInventors: Shigeki Matsubara, Yukie Tokiwa, Kyoko Imai, Tomonori Mimura
