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: 8409507Abstract: An automatic analyzer includes a status table storing the status of each analysis module and reagent information identifying each reagent, the supply of which is exhausted, and allowing tracking of the status of each analysis module, etc. The automatic analyzer determines, based on the status table, whether and how it can continue current analysis, and stores the determination results in its instruction information table. The instruction information table stores analysis-unit or -module operating information and information to be supplied to the user or operator. The analysis-unit operating information includes instructions for the analysis modules to initiate an analysis in a normal manner, finish an analysis in a normal manner, omit a pre-analysis operation, omit a post-analysis operation, or stop sampling, etc. Further, the reagent information and the analysis module status are updated each time a reagent container is replaced by the operator.Type: GrantFiled: March 27, 2008Date of Patent: April 2, 2013Assignees: Hitachi High-Technologies Corporation, Roche Diagnostics Operations, Inc.Inventors: Hirokazu Iwamatsu, Kazuhiro Nakamura, Satoshi Shibuya, Yasunao Awata, Hidetoshi Sugiyama, Werner Doppen, Dietmar Kappelhoff
