Patent number: 11953509Abstract: The automatic analyzer includes a housing unit capable of housing a plurality of reagent bottles each of which has an IC tag on one surface of short-side side surfaces thereof, an antenna used to communicate with the IC tag, a detector that detects the presence or absence of a reagent bottles, and a control unit. The housing unit includes a housing container cooled by a cooling machine, a heat insulating material, a reagent tray provided with a plurality of reagent bottle holding portions that hold the reagent bottles, a disk rotatably holding the reagent tray, and a driving unit driving the disk, and when it is unable to communicate with the IC tag of the reagent bottle installed in the reagent bottle holding portion where the reagent bottle is detected by the detector, the control unit determines that the reagent bottle is installed in a reverse direction.Type: GrantFiled: January 20, 2020Date of Patent: April 9, 2024Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Yudai Fukushi, Ryosuke Funahashi

Patent number: 11953513Abstract: An automated analyzer is provided that includes a sample probe for dispensing a substance to be dispensed into a plurality of reaction vessels for causing a sample to be analyzed to react with a reagent, a measurement unit (e.g., light source, spectrophotometer, and control device) for measuring a reaction liquid produced from the sample and reagent in a reaction vessel, a cleaning tank for probe cleaning, and a control device for controlling the operation of the probe, measurement unit, and cleaning tank. The cleaning tank includes a cleaning pool for storing cleaning water for immersing and cleaning the probe and a drying tank for sucking up the cleaning water on the surface of the probe after the probe has been immersed in the cleaning water of the cleaning water pool and cleaned. As a result, it is possible to reduce the amount of cleaning water used to clean the probe.Type: GrantFiled: September 20, 2019Date of Patent: April 9, 2024Assignee: Hitachi High-Tech CorporationInventors: Yudai Fukushi, Takamichi Mori

Publication number: 20240003926Abstract: An automatic analyzer capable of positioning in a short time is provided. The automatic analyzer includes: a rotation mechanism configured to rotate, in a circumferential direction in a horizontal plane, a nozzle configured to perform at least one of aspiration of a fluid in a container accommodated in an accommodation portion disposed on a trajectory during rotation and discharge of the fluid to the container; a height positioning mechanism configured to position a position adjustment tool accommodated in the accommodation portion in a height direction by driving the nozzle; and a circumferential positioning mechanism configured to position the accommodation portion accommodating the position adjustment tool in a circumferential direction by bringing the nozzle into contact with the position adjustment tool from a side thereof after a height position of the position adjustment tool is determined.Type: ApplicationFiled: September 28, 2021Publication date: January 4, 2024Inventor: Yudai FUKUSHI

Publication number: 20230121166Abstract: Provided is an automatic analyzer in which a lid of a reagent vessel does not hinder the dispensing of the reagent. An automatic analyzer for analyzing a specimen includes a reagent dispensing unit for dispensing a reagent from a reagent bottle in which a plurality of reagent vessels storing reagents used for the analysis of the specimen are arranged in one direction, and a reagent rack in which reagent bottles are stored, in which the reagent rack includes a lid opening unit for opening a lid corresponding to an upward opening of the reagent vessel along an arrangement direction of the reagent vessels, and a lid fixing unit for fixing the lid to the outside of a path in which the reagent dispensing unit is inserted into the opening.Type: ApplicationFiled: December 1, 2020Publication date: April 20, 2023Inventors: Yudai FUKUSHI, Yasuhiro KETA, Eiichiro TAKADA, Fuka MATSUDAIRA, Ai MASUDA, Takanori NISHIYAMA

Patent number: 11360111Abstract: Provided is a connection module with a high degree of freedom for an automatic analyzer which does not depend on a device as a discharge destination. For this purpose, a module to be connected to an automatic analyzer with a rack rotor mechanism includes: a rack discharge mechanism for moving a rack from the rack rotor mechanism to a rotation holder; a rack rotating mechanism for rotating the rack moved to the rotation holder; a conveyor mechanism for transporting the rack from the rack rotating mechanism to a discharge port; and a feeder mechanism for pushing the rack out of the rotation holder to the conveyor mechanism, in which the rack rotating mechanism rotates the rotation holder from a direction parallel to the rack discharge mechanism to a direction parallel to the feeder mechanism and the conveyor mechanism in the selected rotation direction.Type: GrantFiled: August 23, 2018Date of Patent: June 14, 2022Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Yudai Fukushi, Takamichi Mori

Publication number: 20220057422Abstract: This automated analyzer 100 comprises: a sample probe 11a for dispensing a substance to be dispensed into a plurality of reaction vessels 2 for causing a sample to be analyzed to react with a reagent, a measurement unit (light source 4a, spectrophotometer 4, and control device 21) for measuring a reaction liquid produced from the sample and reagent in a reaction vessel 2, a cleaning tank for probe cleaning, and a control device 21 for controlling the operation of the probe, measurement unit, and cleaning tank 13. The cleaning tank 13 comprise a cleaning pool 36 for storing cleaning water for immersing and cleaning the probe and a drying tank 37 for sucking up the cleaning water on the surface of the probe after the probe has been immersed in the cleaning water of the cleaning water pool 36 and cleaned. As a result, it is possible to reduce the amount of cleaning water used to clean the probe.Type: ApplicationFiled: September 20, 2019Publication date: February 24, 2022Inventors: Yudai FUKUSHI, Takamichi MORI

Patent number: 11079402Abstract: Provided is an automatic analyzer that has a plurality of mechanisms including a mechanism that suctions reaction waste liquid and a mechanism that suctions cleaning liquid, etc. on a sample and a probe surface, the automatic analyzer reducing pressure in a vacuum tank using a pressure-reducing pump, etc., and suctioning waste liquid by negative pressure in the vacuum tank. A contact point of a vacuum switch that is provided in the vacuum tank is closed when the pressure in the vacuum tank reaches a specified negative pressure, and then the analyzer becomes ready for analysis. If any flow path portion of any mechanism that connects with the vacuum tank becomes clogged, suctioning operation cannot be performed properly and analysis performance is affected. The vacuum pump is switched off at a timing at which each solenoid valve connecting to the vacuum pump is individually opened, and the time that elapses before the pressure in the vacuum tank reaches the specified negative pressure is measured.Type: GrantFiled: January 23, 2019Date of Patent: August 3, 2021Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Yudai Fukushi, Takamichi Mori
