Patent number: 11391750Abstract: A sample-processing system that improves total system processing efficiency, and reduces a sample-processing time, by establishing a functionally independent relationship between a rack conveyance block with rack supply, conveyance, and recovery functions, and a processing block with sample preprocessing, analysis, and other functions. A buffer unit with random accessibility to multiple racks standing by for processing is combined with each of multiple processing units to form a pair, and the system is constructed to load and unload racks into and from the buffer unit through the rack conveyance block so that one unprocessed rack is loaded into the buffer unit and then upon completion of process steps up to automatic retesting, unloaded from the buffer unit. Functional dependence between any processing unit and a conveyance unit is thus eliminated.Type: GrantFiled: July 6, 2018Date of Patent: July 19, 2022Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Hitoshi Tokieda, Yoshimitsu Takagi, Takeshi Shibuya, Masashi Akutsu

Patent number: 10962558Abstract: An automatic analyzer is capable of ensuring sufficient nozzle cleaning and suppressing of deterioration in the accuracy of analysis. When it is judged that there remains no analysis item of the sample, a judgment is made on whether the sample dispensation quantity of the n-th sample dispensation is less than a dispensation quantity threshold value or not, and if less, a cleaning pattern is selected by making a judgment on whether or not all the sample dispensation quantities of the first through (n?1)-th sample dispensations are less than the dispensation quantity threshold value. If the sample dispensation quantity of the n-th sample dispensation is the dispensation quantity threshold value or more, another cleaning pattern selected by making the judgment on whether or not all the sample dispensation quantities of the first through (n?1)-th sample dispensations are less than the dispensation quantity threshold value.Type: GrantFiled: January 3, 2018Date of Patent: March 30, 2021Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Akihiro Yasui, Hitoshi Tokieda, Toshihide Orihashi, Yoshiaki Saito, Naoto Suzuki

Patent number: 10539584Abstract: A CTS nozzle achieves the object of reducing rubber chips produced when the CTS nozzle is inserted into and extracted from a rubber plug of a sample container during dispensing of a sample, thereby inhibiting the wear of the tip of the CTS nozzle. The CTS nozzle has two cut surfaces at its tip, and the pressure applied from the rubber when the nozzle is inserted into the rubber plug is dispersed onto the two cut surfaces without being deflected onto one of the cut surfaces. The pressure applied to the nozzle due to the resilience of the rubber being pushed away by the nozzle is thus dispersed and the rubber chips produced by the friction between the cut surfaces of the nozzle and the rubber are reduced. As a result of the reduced friction, the wear of the tip of the nozzle is minimized.Type: GrantFiled: December 7, 2015Date of Patent: January 21, 2020Assignee: Hitachi High-Technologies CorporationInventors: Yosuke Horie, Tomohiro Inoue, Hitoshi Tokieda, Takamichi Mori

Patent number: 10302668Abstract: In a case where a sample container 15 has a rubber-made lid 35, if a sample nozzle descends and comes into contact with the lid, the sample nozzle is relatively moved inside an arm as far as a lid detection distance, and a detector detects a detection plate. A fact that the sample nozzle comes into contact with the lid is stored together with position information of the sample nozzle, into an operation commanding unit. The sample nozzle further continues to descend, and a suction operation of a sample is performed at a predetermined position. In a case where the sample nozzle collides with a frame portion of the lid and external force is applied thereto, the detector detects that the detection plate is relatively moved as far as the detection distance.Type: GrantFiled: January 5, 2015Date of Patent: May 28, 2019Assignee: Hitachi High-Technologies CorporationInventors: Akihiro Yasui, Yoshihiro Suzuki, Kazuhiro Nakamura, Hitoshi Tokieda

Patent number: 10184948Abstract: An automated analyzer maintains high processing capacity and dispensation accuracy even when items requiring dilution/pretreatment and general reaction measurement are mixed. A plurality of sample dispensing mechanisms are independently driven and each include a sample collection position, a sample nozzle for collecting the sample, and a washing tank for washing the sample nozzle. The sample dispensing mechanisms are configured to collect the sample from a plurality of sample collection positions and are operated independently to perform sample dispensation into reaction containers on a reaction disc. At least one of the sample dispensing mechanisms is provided for each of a sample requiring dilution/pretreatment and a sample that does not require dilution/pretreatment. The automated analyzer is provided with a control means for causing the respective mechanisms to be operated in a dedicated manner. The sample is dispensed such that no vacancy is created in the reaction containers.Type: GrantFiled: August 24, 2016Date of Patent: January 22, 2019Assignee: Hitachi High-Technologies CorporationInventors: Akihiro Yasui, Yoshihiro Suzuki, Hitoshi Tokieda
