Description

Technical Field The present invention relates to an automatic analysis system including an automatic analyzer or the like and an alarm handling method for analyzing an analyte derived from a biological sample such as blood or urine. Background Art An automatic analyzer that analyzes a biological sample such as blood or urine has merits such as high reproducibility of analysis accuracy and a high analysis processing speed, and thus is indispensable for current diagnosis. There are a plurality of types of such automatic analyzer depending on the analysis type. Examples include a colorimetric analyzer that performs biochemical analysis, an immunoanalyzer that analyzes an antigen or antibody in a sample using an antigen-antibody reaction, a coagulation analyzer that measures coagulability of blood, a blood cell counter that measures the number of blood cell components in blood, and the like. When analyzing a sample by the automatic analyzer, a pre-processing device that performs pre-processing such as centrifugation of blood or dispensing of the sample to prepare a plurality of child analytes is also used. In a hospital, inspection center, and the like, it is common to use a plurality of such automatic analyzers and sample pre-processing devices. When an error occurs in such an automatic analyzer or sample pre-processing device, analysis may be stopped and a diagnosis made by a doctor may be delayed if the error is not immediately handled. Examples of the error include reagent replacement and replacement of a consumable such a lamp. PTL 1 discloses a technique of, when an error occurs, notifying a person-in-charge of the error and sharing who handles the error, based on information that registers errors that can be handled by the person-in-charge. PTL 2 describes a technique of, when an error occurs, notifying a person-in-charge of the error based on information that registers errors that can be handled by the person-in-charge, position information of the person-in-charge and a device generating the error, and schedule information of the person-in-charge which is used to confirm whether the person-in-charge is working. Citation list Patent Literature PTL 1: WO2013/065528 corresponding to EP 2775307 A1 from which the pre-characterising part of claim 1 starts out.PTL 2: JP-A-2018-160808 Related art is disclosed in US 2019/0079107 A1. Summary of Invention Technical Problem When handling the error, in order to prepare a reagent and a consumable necessary for eliminating the error, the person-in-charge may need to stop at another location such as a reagent storage or a consumable storage before heading to a location where the analyzer generating the error is present. In particular, in a case of a large-scale clinical laboratory, movement of a laboratory technician in charge of the handling of the error also leads to time loss. However, the techniques described in PTLs 1 and 2 have not considered a case where there is a need to access a location other than the device generating the error in order to handle the error, and therefore time loss may occur. An object of the invention is to provide an automatic analysis system that can, when an error occurs in an analyzer, processing device, or the like in a clinical laboratory, optimize assignment of a person-in-charge who handles the error and reduce a time period required for handling the error, even if there is a need to access to a position other than the device generating the error in order to handle the error. Solution to Problem The above problem is solved by an automatic analysis system and an alarm handling method as set forth in the appended claims. Advantageous Effect A time period required for dealing with a case where there is a need to access to another position prior to a device generating an alarm can be reduced. Other problems and novel characteristics will become apparent from a description of the present specification and the accompanying drawings.
