Publication number: 20200141959Abstract: A reagent container transfer mechanism transfers a reagent container selected from among reagent containers stored in a second reagent container storage section to a first reagent container storage section. A controller controls the reagent container transfer mechanism to transfer a reagent container from a second reagent container storage section to the first reagent container storage section on the basis of a predetermined priority condition. The predetermined priority condition is one of a reagent provided with an effective calibration curve result, a number of remaining tests, and an expiration date of a reagent.Type: ApplicationFiled: January 8, 2020Publication date: May 7, 2020Inventors: Masaki SHIBA, Masaaki HANAWA, Masaharu NISHIDA, Hitoshi OTAKE

Patent number: 10309979Abstract: The invention provides a small-sized automatic analyzer being compact, enabling a large number of analysis items to be carried out, and having a high processing speed. The automatic analyzer is particularly suitably applied to a medical analyzer used for qualitative/quantitative analysis of living body samples, such as urine and blood. A plurality of sample dispensing mechanism s capable of being operated independently of each other are provided to suck a sample from any one of a plurality of sample suction positions and to discharge the sucked sample to any one of a plurality of positions on a reaction disk. The automatic analyzer having a high processing capability can be thus realized without increasing the system size.Type: GrantFiled: October 12, 2017Date of Patent: June 4, 2019Assignee: Hitachi High-Technologies CorporationInventors: Hideyuki Yanami, Isao Yamazaki, Masaaki Hanawa, Hitoshi Otake

Patent number: 8877128Abstract: An empty rack transport line is arranged at a lower stage and independent of a main transport line, a fast emergency line and a reverse line. In a rack stocker, an inclined transport line connects the empty rack transport line to the rack stocker. The rack stocker is arranged between a storage module and a loading module. The rack stocker is capable of continuously supplying and collecting empty racks, while transport lines do not cross each other. It is, therefore, possible to continuously supply and collect empty racks in a simple configuration, without an increase in the system size, an intersection of transport lines and a reduction in processing capability. In addition, it is possible to provide an automated sample testing system that is highly extendable for various facility sizes.Type: GrantFiled: September 8, 2010Date of Patent: November 4, 2014Assignee: Hitachi High-Technologies CorporationInventors: Tatsuya Fukugaki, Masaaki Hanawa, Hiroshi Ohga

Patent number: 8833186Abstract: Conventional conveying lines have required building according to the particular shapes of test tube racks and test tube holders. For this reason, at least two types of dedicated lines, one for test tube racks and one for test tube holders, have been needed in one system, so there has been a tendency for systems to be complex in structure and disadvantageous in cost. To solve these problems, this invention provides a sample conveying system designed so that test tube racks and test tube holders can move on the same line, and high in both cost-effectiveness and reliability.Type: GrantFiled: September 8, 2010Date of Patent: September 16, 2014Assignee: Hitachi High-Technologies CorporationInventors: Tetsuya Isobe, Hiroshi Ohga, Masaaki Hanawa, Tatsuya Fukugaki
