Biological Information Displaying Apparatus Alarm Persistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological information displaying systems often fail to ensure that past alarms are not missed and can be difficult to determine if an alarm was caused by an artifact, leading to potential delays in adequate procedures.
Innovation Solution
A biological information displaying apparatus and system that continues to display abnormality information on a dedicated screen until a confirmation process is executed, allowing for the simultaneous display of multiple biological information types, including waveforms and numerical values, to facilitate comprehensive diagnosis and differentiation between genuine and artifact-induced alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the biological signal waveform is displayed in a form of a broken line at alarm time, then the alarm condition can be clearly indicated to the monitoring person, but when the biological signal waveform is recovered from the abnormal condition, the display mode is returned to normal display mode, causing the monitoring person to miss past alarms and making it difficult to determine whether the alarm was caused by artifact contamination
Solution Approach 1:
The system performs preliminary action by continuously retaining alarm information on the display even after the alarm condition is resolved. The abnormal display mode (broken line) is maintained as a historical record, allowing monitoring personnel to review past alarms and determine whether they were caused by artifact contamination or genuine physiological changes.
Solution Approach 2:
The system adds a temporal dimension to the display by showing both current and past alarm states simultaneously. The display screen is divided to show current waveforms and alarm history together, allowing monitoring personnel to compare current conditions with past alarm conditions to assess whether alarms were genuine or artifacts.
2Ease of operation
If monitoring information at alarm notification is displayed on a separate displaying section of a data processing unit, then alarm procedures can be performed, but monitoring information under measurement and monitoring information related to alarm notification cannot be displayed together, making it difficult to check the cause of alarm and perform rapid procedures
Solution Approach 1:
The system merges the displaying section with the data processing unit, integrating alarm information display with real-time monitoring information display. This allows monitoring personnel to view both the alarm notification and the current physiological parameters on the same screen, enabling rapid assessment of whether the alarm was caused by artifact or genuine physiological change and facilitating immediate appropriate procedures.

AI summary
A biological information displaying apparatus includes: a displaying section on which a measurement display screen displaying biological information under measurement and an abnormality display screen displaying information alarming an abnormality of the biological information, and the biological information at a timing when the abnormality occurs are displayed; and a display controlling section which is configured to display the abnormality display screen on the measurement display screen, so that the abnormality display screen is superimposed on the measurement display screen. In case where the abnormality display screen is displayed on the displaying section, the display controlling section controls the displaying section so that, even when the abnormality resolves, the information alarming the abnormality of the biological information, and the biological information at the timing when the abnormality occurs are continued to be displayed on the abnormality display screen.
