Patent number: 11480504Abstract: When the type is to be changed from serum (preceding sample) to urine (current sample), “serum” is set to a preceding type and “urine” is set to a measurement type at number 1 in a condition number. At condition number 1, the wash type is pattern 1, with washing performed once with detergent 1. Where the preceding sample is serum and the current sample is CSF, the condition number is 2 and the wash type is pattern 2, with washing performed twice using detergent 1 and once with detergent 2. Where the preceding sample is urine and the current sample is CSF, the condition number is 3 and the wash type is pattern 3, with washing performed once with detergent 1, once with detergent 2, and once with water. In the case of pattern 4, washing is performed three times with detergent 1.Type: GrantFiled: January 30, 2018Date of Patent: October 25, 2022Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Naoto Suzuki, Yoshiaki Saito, Yoichi Aruga, Toshihide Orihashi, Kazuhiro Nakamura

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: 10094844Abstract: In determining whether a rack inputted to the automatic analyzer by the user is to be transferred to an analysis section or not, samples existing in a route from a buffer to a sample dispensing position in the analysis section are identified, and the number of items in which suction by a nozzle has not been completed in analysis items requested for the samples is managed. When the number of items is reduced to be smaller than a given number, the conveyance of a next rack from the buffer to the analysis section is controlled, thereby limiting the number of analysis items requested for samples in a waiting state for analysis in the analysis section constantly to be smaller than a fixed number. As a result, a period of time until a measurement result of emergency samples is outputted can be reduced even when emergency samples are newly inputted.Type: GrantFiled: June 29, 2012Date of Patent: October 9, 2018Assignee: Hitachi High-Technologies CorporationInventors: Yoshiaki Saito, Kazuhiro Nakamura, Naoto Suzuki, Toshihide Orihashi

Patent number: 9618526Abstract: An automated analyzer that can effectively reduce contamination of a diluted low-concentration specimen resulting from a high-concentration specimen not being diluted. The automated analyzer includes a specimen nozzle that performs both the function of pipetting a specimen from a specimen container accommodating the specimen and the function of pipetting a specimen diluted by the analyzer, and means for washing the specimen nozzle with a predetermined detergent. When a pipetting process of a high-concentration specimen not being diluted and a pipetting process of a low-concentration specimen diluted by the analyzer are consecutively performed for the same specimen by the specimen nozzle, between the pipetting process of a high-concentration specimen and the pipetting process of a low-concentration specimen, the analyzer performs a washing processing in which the specimen nozzle is washed with the predetermined detergent.Type: GrantFiled: July 8, 2013Date of Patent: April 11, 2017Assignee: Hitachi High-Technologies CorporationInventors: Yoshiaki Saito, Yoichi Aruga, Toshihide Orihashi

Patent number: 9341638Abstract: An automatic analyzer enables users to perform working steps easily and reliably by switching a display screen irrespective of a skill level of the user. The automatic analyzer, which determines a consistency of a test item, includes a display/input section to display a plurality of working steps relating to necessary work flow for measurement. The display/input section is adapted to selectively present a maximized workflow display and a reduced workflow display. The maximized workflow display shows a series of operations and works, and further shows a plurality of operations and works in an order that the plurality of operations and works are processed. In a reduced display of the work flow, the reduced workflow display shows details of a specific operation or work, and a position of the specific operation or work in a sequence that the entire series of operations and works are processed.Type: GrantFiled: May 22, 2012Date of Patent: May 17, 2016Assignee: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Sayaka Sarwar, Tatsuya Tokunaga, Miki Taki, Toshihide Orihashi, Hiroki Mori, Yoichi Aruga, Takashi Nakasawa

Patent number: 9316662Abstract: An automated analyzer includes a conveyance mechanism to convey a specimen, an analysis portion to analyze the specimen, and a device cover to cover a movable mechanism including the conveyance mechanism. The automated analyzer is provided with an interlock mechanism and an interlock release mechanism. The interlock mechanism stops an operation of the movable mechanism when the device cover is opened. The interlock release mechanism disables all or part of the interlock mechanism. The interlock mechanism is enabled when a lever 301 is in contact with a safety switch 302. The interlock mechanism is disabled or partially disabled when the lever 301 is not in contact with the safety switch 302. This enables to prevent a user from inadvertently touching the movable mechanism including a hazard region during analysis of the automated analyzer or a maintenance task. Only a specific maintenance task can be performed with the device cover opened.Type: GrantFiled: August 6, 2012Date of Patent: April 19, 2016Assignee: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Ryohei Ishigami, Toshihide Orihashi, Goro Yoshida, Kenichi Nishigaki, Hideyuki Yanami
