Automatic Analyzer Pre-Operation Timing for Mechanism Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzers do not accurately account for the time required for operation confirmation of mechanisms such as dispensing probes and reaction disks, which can lead to analysis hindrances if initial positions are displaced or abnormalities occur in pressure sensors.
Innovation Solution
An automatic analyzer with a control unit that calculates and displays the remaining time for pre-operations based on the time required for operation confirmation of various mechanisms, including mechanism reset, pressure sensor check, and reagent registration, using pre-operation and post-operation tables to determine and display the necessary times.

Engineering Contradiction Analysis
1Reliability
If operation confirmation of various mechanisms is performed in pre-operation, then reliability of analysis is improved, but time required for pre-operation increases
Solution Approach 1:
The system performs operation confirmation of various mechanisms (dispensing probe position, reaction disk position, pressure sensor status) during the pre-operation phase before actual analysis begins. This preliminary checking ensures that all mechanisms are in proper working condition, preventing analysis interruptions while maintaining efficient timing through accurate estimation and display of remaining pre-operation time.
2Productivity
If accurate estimation of analysis end time is provided, then operator efficiency is improved, but accuracy of time estimation deteriorates due to unaccounted pre-operation time
Solution Approach 1:
The system provides feedback to the operator by displaying the remaining time for pre-operation completion on the display unit. This feedback mechanism allows operators to understand how much time is needed for mechanism confirmation before analysis begins, enabling better work planning and more accurate overall time estimation from analysis instruction to completion.

AI summary
An object of the present invention is to provide an automatic analyzer capable of more accurately obtaining time required for a pre-operation from reception of an analysis instruction to start of analysis. The automatic analyzer includes an analysis module that analyzes a sample, a control unit that controls the analysis module, and a display unit that displays a state of the analysis module. The control unit performs control to calculate remaining time until the pre-operation is completed based on time required for operation confirmation of various mechanisms of the analysis module and display the remaining time on the display unit.
