Automatic Analyzer Alarm Segmentation for Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of automatic analyzers varies by laboratory, leading to mismatches between alarm notifications and laboratory operations, which can cause deterioration in examination efficiency and delays in reporting results.
Innovation Solution
An automatic analyzer with a device state managing unit, abnormality detecting unit, alarm planning unit, and notifying unit that plans and sends specific alarms for abnormality occurrence and handling availability, ensuring timely and appropriate user notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single alarm notification system is used, then the device complexity is reduced, but the examination efficiency deteriorates due to mismatched alarm timing with laboratory operations
Solution Approach 1:
The alarm notification system is segmented into multiple distinct alarm types (abnormality occurrence alarm, handling available alarm, and handling completed alarm) that can be independently configured and notified at different timings. This segmentation allows the system to provide targeted notifications matching specific laboratory operational stages, thereby improving examination efficiency without requiring an overly complex monolithic system.
Solution Approach 2:
The alarm notification system employs dynamic timing configuration where each alarm type can be set to notify at different stages of the abnormality handling process. The system adapts notification timing based on the specific abnormality and laboratory workflow requirements, allowing flexible adjustment between immediate notification, delayed notification until handling is available, and confirmation upon completion, thus optimizing efficiency without fixed complexity.
2Loss of time
If alarm notifications are sent immediately upon abnormality detection, then the response time is reduced, but the examination efficiency deteriorates when the analyzer is not yet available for handling
Solution Approach 1:
The system performs preliminary assessment of analyzer availability before sending handling notifications. When an abnormality is detected, the system first evaluates whether the analyzer is in a state ready for handling (e.g., current measurements completed, no blocking errors). Only when this preliminary condition is satisfied does the system notify the user, preventing premature notifications that would waste user time while maintaining rapid response through immediate abnormality detection and assessment.
3Loss of information
If multiple alarm types are implemented, then the information accuracy is improved, but the device complexity increases
Solution Approach 1:
Different alarm types are designed with specific local qualities tailored to their notification purposes. The abnormality occurrence alarm provides immediate alert information, the handling available alarm provides status confirmation information, and the handling completed alarm provides closure information. Each alarm type contains precisely the information needed for its specific function, avoiding information overload while maintaining high information accuracy for each notification stage.
Solution Approach 2:
The multiple alarm types create a feedback loop that provides comprehensive information about the abnormality handling process. The system notifies of the abnormality, then provides feedback when handling becomes available, and finally confirms when handling is completed. This feedback mechanism ensures complete information transfer about the abnormality status and handling progress, improving information accuracy through structured communication rather than complex data processing.

AI summary
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.
