Publication number: 20200191809Abstract: Provided is a sample transport system capable of avoiding insertion of a sample into an automatic analysis device even when the inability of the automatic analysis device to carry out processing is detected after the sample is transported from a sample preprocessing system. A carrier transfer machine determines whether a sample transferred from a sample transport system unit can be analyzed by an automatic analysis device based on sample information about the sample and information about whether a reagent is loaded in the automatic analysis device, and, if a determination is made that the sample cannot be analyzed, moves a sample container holder to the sample transport system unit without transferring a sample container to a carrier. As a result, it is possible to avoid inserting a sample into an automatic analysis device that is not capable of carrying out analysis on the sample and eliminate unnecessary operations and time.Type: ApplicationFiled: January 16, 2017Publication date: June 18, 2020Inventors: Noriyuki AIZAWA, Tadao SHIMIZU

Patent number: 9632100Abstract: A host system recognizes a sample pretreatment system at which a primary sample has first arrived and records the information, if multiple containers containing the primary sample are input. Upon issuing an analysis request to the sample pretreatment system, the host system determines whether the primary sample (sample bearing the same barcode for sample identification) is input to a system different from the system to which the sample was input for the first time and, if that is the case, then determines that “the sample is input to the wrong system” and issues a “do-nothing request” (request to do nothing) so that an aliquoting operation will not be performed. Given the “do-nothing request” from the host system, the sample pretreatment system does not prepare any aliquot sample and places the input sample onto a tray in a predetermined position.Type: GrantFiled: December 18, 2012Date of Patent: April 25, 2017Assignee: Hitachi High-Technologies CorporationInventors: Iwao Suzuki, Tadao Shimizu, Shigeru Yano, Koji Kamoshida
