Patent number: 11161118Abstract: The mixing of reagents with each other in the reagent storage flow paths of an automatic analyzer is suppressed before and after exchange of the reagents, which are capable of being replenished without stopping analysis. An exchangeable reagent container that accommodates a reagent is connected to a reagent storage flow path that stores a portion of the reagent. The reagent storage flow path has first and second flow paths in which the second flow path is branched from the first flow path. A reagent syringe applies a negative or a positive pressure to the first and second flow paths; and a valve controls the flow path through which the reagent is sent. As a result, the reagent supplied to a measurement portion at a predetermined timing is switched from the reagent container to the reagent storage flow path wherein the reagent can be supplied without stopping analysis.Type: GrantFiled: February 15, 2018Date of Patent: November 2, 2021Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Hiroki Fujita, Toshiharu Suzuki, Takenori Okusa, Shunsuke Sasaki, Yoshihiro Yamashita, Kenta Imai

Patent number: 10920821Abstract: [Problem] To provide a terminal securing device the size of which can be reduced. [Solution] When a key lock 7 is positioned in a second position a key 6 and the key lock 7 are arranged at overlapping positions in the lengthwise direction of a rod 3, so a portion of a space for displacing the key lock 7 from the second position to a first position can be provided at a position overlapping the key 6 in the lengthwise direction of the rod 3. Thus, an increase in the size of a holder 4 in the lengthwise direction of the rod 3 can be avoided, so the size of the terminal securing device 1 can be reduced.Type: GrantFiled: July 24, 2018Date of Patent: February 16, 2021Assignee: CHUO HATSUJO KABUSHIKI KAISHAInventors: Kenta Imai, Shinji Okamoto, Seiji Yamada

Patent number: 10768189Abstract: When a sample of biological origin in an aqueous solution is used as the measurement medium in analysis using an electrochemical process, and a voltage of +1.2 V or greater (with saturated silver-silver chloride electrode potential as a reference) is applied, there are instances in which bubbles are observed to be produced within the flow cell, due to an electrolysis reaction deriving from the measurement buffer. There is a possibility that bubbles produced on the electrode will cover the electrode surface, reducing the effective surface area of the electrode. Also, the distribution of magnetic particles captured on the electrode will be disturbed by the gas produced thereby, lowering the reproducibility of the results of the analysis. Deaeration of the measurement medium prior to introduction of the measurement medium into the detector minimizes the effects of bubble production in degrading the analytical capability makes it possible to carry out highly sensitive electrochemical analysis.Type: GrantFiled: January 9, 2015Date of Patent: September 8, 2020Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Kenta Imai, Yoshinori Negishi, Toshinari Sakurai, Kyoko Imai
