An analysis method of an automatic analyzer is provided. The automatic analyzer includes: an insertion unit into which a rack is inserted; a transport line that transports the rack; a detection unit that detects a rack identifier from a rack or an attribute from a sample container which accommodates therein a sample as an object to be examined and which is mounted on a rack; an analysis module that includes a light source and a spectrometer which measures a measurement value to analyze a sample; a rack standby unit in which a rack stands by; and, a rack recovery unit that recovers a rack. In the automatic analyzer, a rack stands by in the rack standby unit until a measurement result in the analysis module is output; and is then recovered to the rack recovery unit. The analysis method includes: a step of transporting a rack from the rack insertion unit to the transport line, making the transported rack stand by until a measurement result in the analysis module is output, and then recovering the rack to the rack recovery; a step of detecting an identifier from the rack or an attribute from a sample container accommodating a sample and mounted on the rack; and a step of, when a rack transported subsequent to the rack of interest is transported from the rack insertion unit to the transport line, recovering the subsequent rack to the rack recovery unit without standing by in the rack standby unit.

Analysis method of automatic analyzer

Provided is an automatic analyzer that can perform a reagent preparation/disposal operation comfortably and smoothly as when printing a reagent list such as a reagent preparation/disposal list on paper even without printing the reagent list. The automatic analyzer that performs analysis using a sample and a reagent, the automatic analyzer including: a storage unit that stores reagent information related to a reagent remaining amount or a reagent expiration date of each of reagent containers; and a display unit that displays a reagent list in which reminder information that gives a reminder to an operator is assigned to each of setting positions of the reagent containers based on the reagent information stored in the storage unit. The reagent managing unit updates display of the reagent list such that a reagent container selected by the operator is visually identifiable while the reagent list is displayed.

Automatic analyzer, automatic analysis system, and display method of reagent list

Reducing screen shift operations performed in confirming a device status of an automated analysis device efficiently enhances inspection work. A tablet terminal is used to obtain device information indicating the device status of an automated analysis device and to create and display a status confirmation screen indicating the device status based on the obtained device information. The status confirmation screen has a first display area showing each device button corresponding to each of the automated analysis devices coupled to the tablet terminal and a second display area showing the device status of the automated analysis devices corresponding to the selected device button. Based on the device information of the automated analysis device corresponding to the selected device button, the information management unit creates a status screen indicating the device status in the automated analysis device and controls the display to show the status screen.

Automated analysis system

Work, such as status confirmation, in a plurality of automatic analyzers is efficiently performed. In an automated analysis system, a tablet terminalhas a terminal information management unitand a terminal display unit. A terminal information management unitacquires device information showing the state status of a device from automatic analyzersto, and generates a status confirmation screen showing the device status of the automatic analyzer. A terminal display unitdisplays the status confirmation screen. The status confirmation screen has a status information screen showing the device status of one automatic analyzer and a device switch button configured to switch the status information screen to a status information screen corresponding to another other automatic analyzer. When the switch button is selected, the terminal information management unitgenerates a status confirmation screen for an automatic analyzer corresponding to the selected switch button, and displays the status confirmation screen on the display unit.

The automatic analyzer includes: a device state managing unit that manages a device state of the automatic analyzer; an abnormality detecting unit that detects abnormality of the automatic analyzer based on information of the device state managed by the device state managing unit and a predetermined reference; an alarm planning unit that plans at least two alarms including an abnormality occurrence alarm and an handling available alarm regarding each of abnormality items detected by the abnormality detecting unit, the abnormality occurrence alarm being planned for notification to a user in a case where the abnormality occurs, and the handling available alarm being planned for notification to the user in a case where the automatic analyzer is in a device state where the automatic analyzer is available for handling the abnormality; and a notifying unit that notifies the alarms planned by the alarm planning unit.

Automatic analyzer

Provided is an automatic analyzer capable of switching an apparatus operation mode, such as automatic reexamination, without stopping measurement by efficiently using a rack. The automatic analyzer includes a storage unit that stores an operation mode, such as automatic reexamination, of the automatic analyzer, a detection unit that detects an operation mode switching rack inserted into an insertion unit, and a control unit that switches the operation mode stored in the storage unit on the basis of the detection of the operation mode switching rack by the detection unit. The control unit applies the switched operation mode to an examination object rack transported from the insertion unit to a transport line after the operation mode switching rack.

It is an object to provide a system for a service department to contact a customer for improving customer service when it is determined that the customer has difficulty in handling an alarm by themselves in the case where the alarm is generated due to abnormality of an automatic analyzer and the automatic analyzer is deactivated. The automatic analyzer includes: a display to display an alarm screen; a computer that generates alarm generation information that indicates that an alarm has been generated due to abnormality and alarm deletion information that indicates that the customer has deleted the alarm displayed on the alarm screen based on the alarm generation information; and an information sharing portion that shares the alarm generation information and alarm deletion information that are generated by the computer with an external alarm maintenance system.

Automatic analyzer, remote maintenance system, and maintenance method

Disclosed is an automatic analysis device in which a check item at a time of an analysis start can be set in accordance with a skill level of an operator, an analysis can be performed after the check item being displayed and confirmed, and erroneous measurement caused due to a missed check can be prevented. The check item such as checking the remaining quantity of a reagent or the like displayed in a check screen before the analysis start can be set for each type of operator, each day, each time. The set check item is configured to be displayed in a screen before the analysis start, and unless the operator confirms the check item, the analysis start is not allowed in principle. An automatic analysis device which can prevent erroneous measurement caused due to a missed check of the operator before the analysis start is realized.
