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

Publication number: 20240042448Abstract: There is provided an automatic analyzer and a method of storing reagents in an automatic analyzer, in which restrictions on installation of reagent packs are smaller than those of the device in the related art. The automatic analyzer includes a reagent storage 105 that stores reagent packs 201, 301 containing reagents. The reagent storage 105 includes: a first holding unit 403 capable of holding only an immune reagent pack 201 containing a first reagent among the reagents; a second holding unit 404 capable of holding only a biochemical reagent pack 301 containing a second reagent that is different from the first reagent; and a third holding unit 405 capable of holding both the immune reagent pack 201 and the biochemical reagent pack 301.Type: ApplicationFiled: November 29, 2021Publication date: February 8, 2024Inventors: Hiroya UMEKI, Akihiro YASUI, Hidetsugu TANOUE

Patent number: 11639943Abstract: There is provided an automatic analysis device that can easily realize introduction and replacement of additional reagents in operation even in a small-scale configuration. The automatic analysis device includes a reagent dispensing mechanism 107 that dispenses a reagent from a reagent container 113 containing a reagent, and a normal reagent storage portion 130 that stores a reagent container and an additional reagent storage portion 111. The normal reagent storage portion 130 is positioned in a normal movable area 132, which is a portion of a movable area 131 of the reagent dispensing mechanism 107 and the additional reagent storage portion 111 is positioned in an area excluding the normal movable area 132 in the movable area 131 of the reagent dispensing mechanism 107.Type: GrantFiled: June 21, 2018Date of Patent: May 2, 2023Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Kenta Imai, Hiroya Umeki, Shunsuke Sasaki, Yoshihiro Yamashita, Taku Sakazume

Publication number: 20230010798Abstract: The invention has an object to provide an automatic analyzer and a control program that can shorten total analysis time. The automatic analyzer comprises: a sample rack that houses a sample; a sample dispensing mechanism that aspirates the sample from the sample rack and dispenses the sample into a reaction container; a plurality of detection units that detect a reaction liquid in the reaction container; and a control unit that controls the sample dispensing mechanism and the detection units. The control unit checks the measurement item specified for the sample and checks one of the detection units that is specified by the measurement item. When measurements specifying the same detection unit among the detection units are specified consecutively, the order of dispensing by the sample dispensing mechanism is changed so that measurements specifying different detection units are made consecutively.Type: ApplicationFiled: October 27, 2020Publication date: January 12, 2023Inventors: Yuichiro OTA, Kenta IMAI, Shunsuke SASAKI, Hidekazu TEZUKA, Hiroya UMEKI

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: 20210215728Abstract: Provided is an automatic analyzer in which a consumable is appropriately managed and efficiently used. An automatic analyzer includes: a housing container holder portion that holds a housing container housing a consumable; a transport mechanism that transports the consumable housed in the housing container; and a controller, in which the housing container contains a first consumable and a second consumable, and the controller determines a usage state of the housing container relating to the first consumable and a usage state of the housing container relating to the second consumable, determines whether or not the first consumable housed in the housing container is usable based on the usage state of the housing container relating to the first consumable, and determines whether or not the second consumable housed in the housing container is usable based on the usage state of the housing container relating to the second consumable.Type: ApplicationFiled: July 4, 2019Publication date: July 15, 2021Inventors: Hiroya UMEKI, Takenori OKUSA, Shunsuke SASAKI, Kenta IMAI, Hiroki FUJITA
