Patent number: 11959914Abstract: The automatic analyzer includes: a sample dispensing unit that dispenses a sample into a reaction vessel; a reagent dispensing unit that dispenses a reagent into the reaction vessel; a control unit that controls the sample dispensing unit and the reagent dispensing unit; and a measurement unit that measures a mixed solution of the sample and the reagent mixed in the reaction vessel. The reagent includes three types of reagents of: a first reagent that specifically binds to an antigen in the sample; a second reagent that specifically binds to a site different from that to which the first reagent binds with respect to the antigen and has a label to be detected by the measurement unit; and a third reagent that specifically binds to a site different from the binding site of the first reagent and the antigen and contains insoluble carriers.Type: GrantFiled: January 29, 2019Date of Patent: April 16, 2024Assignees: HITACHI HIGH-TECH CORPORATION, ROCHE DIAGNOSTICS OPERATIONS, INC.Inventors: Tatsuki Takakura, Kenta Imai, Takaaki Hagiwara, Yoshihiro Yamashita, Taku Sakazume, Beatus Ofenloch-Haehnle, Michaela Windfuhr, Ursula Pauselius-Fuchs, Rita Haerteis

Publication number: 20240118298Abstract: There is provided an automatic analyzer and a control method of the automatic analyzer capable of coping with various operational environments. A storage unit 127 of an automatic analyzer 101 stores information on a priority of dispensing among various samples and information on a constraint condition of the priority of dispensing of the various samples. A control unit 128 controls, based on the information on the priority and the information on the constraint condition, an operation of a sample disk 102 and a sample dispensing mechanism 104 such that the samples are sequentially dispensed from a sample of a type having a highest priority while following the constraint condition.Type: ApplicationFiled: November 19, 2021Publication date: April 11, 2024Inventors: Hitomi NISHIMURA, Hiroya UMEKI, Tatsuki TAKAKURA

Patent number: 11499983Abstract: [Task] To provide an automatic analysis apparatus including a photomultiplier tube which controls a sensitivity of the photomultiplier tube without adjusting a high voltage value. [Solution] An automatic analysis apparatus according to the present invention includes a photomultiplier tube which detects light from a reaction vessel; a determination unit which determines an output signal of the photomultiplier tube in a case where the photomultiplier tube is irradiated with first light; and a control unit which irradiates the photomultiplier tube with second light to lower a sensitivity of the photomultiplier tube in accordance with a determination result by the determination unit.Type: GrantFiled: November 19, 2018Date of Patent: November 15, 2022Assignee: Hitachi High-Tech CorporationInventors: Shunichirou Nobuki, Koshin Hamasaki, Taku Sakazume, Yoshihiro Yamashita, Hidetsugu Tanoue, Tatsuki Takakura

Patent number: 11486890Abstract: To provide an automated analyzer capable of shortening analysis time. The automated analyzer includes a vessel which contains a mixed solution of a specimen and a reagent; and a control unit which controls a first operation performed on the vessel, a second operation performed on the vessel after the first operation, and a third operation performed on a predetermined mechanism of the automated analyzer before the second operation, in which the control unit performs the first operation and the third operation in parallel. Alternatively, the automated analyzer includes a control unit which controls a first operation performed on the vessel, a second operation performed on the vessel after the first operation, and a third operation performed on a predetermined mechanism of the automated analyzer after the first operation, in which the control unit performs the second operation and the third operation in parallel.Type: GrantFiled: November 15, 2018Date of Patent: November 1, 2022Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Kenta Imai, Shunsuke Sasaki, Hiroya Umeki, Tatsuki Takakura, Takenori Okusa, Hiroki Fujita, Taku Sakazume

Publication number: 20210341503Abstract: Provided is an automatic analyzer in which user work is in conjunction with apparatus driving and operation of a user even in complicated maintenance work is simplified. The automatic analyzer includes a measurement device 2 and a control device 3. The control device controls the measurement device. The control device includes an input unit 32 that receives a start instruction of maintenance work by a user, a control unit 31 that controls an apparatus to perform a predetermined first processing in accordance with input, a driving unit that performs driving in accordance with processing of the control unit, a display unit 33 that displays a second processing to be performed by the user in conjunction with the first processing after the first processing is terminated by the driving unit. The control device sequentially guides maintenance work of the user by performing the first processing or the second processing after the displayed second processing is executed by the user.Type: ApplicationFiled: November 13, 2019Publication date: November 4, 2021Inventors: Marina NAKAI, Tatsuki TAKAKURA, Shunsuke SASAKI, Kenta IMAI

Publication number: 20210102964Abstract: Provided is a signal processing apparatus including a first measurement unit which acquires a first time-series signal with a first time resolution; a second measurement unit which acquires a second time-series signal with a second time resolution higher than the first time resolution; and a determination unit which determines a measurement abnormality based on the second time-series signal. The normal measurement is performed based on the first time-series signal while the measurement abnormality determination is performed based on the acquired second time-series signal.Type: ApplicationFiled: November 21, 2018Publication date: April 8, 2021Inventors: Makiko YOSHIDA, Shunsuke SASAKI, Tatsuki TAKAKURA
