Biological Information Display Simultaneous Waveform Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient monitoring systems require multiple page turns to compare arrhythmia waveforms before, during, and after the occurrence and termination of arrhythmia, making it difficult to quickly check rhythm changes.
Innovation Solution
A biological information displaying apparatus and method that simultaneously displays a first waveform group consisting of the initial and preceding arrhythmia waveform, and a second waveform group consisting of the last and succeeding arrhythmia waveform, allowing for easy and instantaneous comparison of rhythm changes.

Engineering Contradiction Analysis
1Loss of time
If waveforms are displayed one page at a time in sequential order, then the display structure remains simple and easy to operate, but multiple page turns are required to compare waveforms before and after arrhythmia occurrence, increasing the time needed to check rhythm changes
Solution Approach 1:
The continuous waveform data is segmented into distinct groups: pre-arrhythmia waveforms, initial arrhythmia waveforms, and post-arrhythmia waveforms. These segmented groups are then selectively displayed together on a single screen, allowing rapid comparison without sequential page turning while maintaining clear visual organization of each waveform type.
Solution Approach 2:
The patent transitions from a single-dimensional sequential display (one page at a time) to a multi-dimensional simultaneous display showing multiple waveform groups across different time periods on the same screen. This dimensional change allows clinicians to compare pre-arrhythmia, initial, and post-arrhythmia waveforms instantly without navigating through multiple pages.
2Loss of information
If all continuous waveforms are displayed at once, then all waveform data is visible for comparison, but the display becomes complex and difficult to interpret
Solution Approach 1:
Instead of displaying all continuous waveforms as a single complex stream, the patent segments the waveforms into meaningful groups (pre-arrhythmia, initial arrhythmia, post-arrhythmia) and displays each group separately. This segmentation preserves complete waveform information while organizing it in a visually manageable format that reduces display complexity.
Solution Approach 2:
Different regions of the display are assigned different qualities and purposes: one area shows pre-arrhythmia waveforms for baseline comparison, another shows initial arrhythmia waveforms for onset analysis, and a third shows post-arrhythmia waveforms for termination analysis. This local differentiation allows complete information display with reduced overall complexity by giving each section a specific functional quality.

AI summary
A biological information displaying apparatus includes an analyzing unit and a display unit. The analyzing unit analyzes measured continuous biological information waveforms to detect abnormal biological information waveforms. The display unit simultaneously displays a first waveform group consisting of continuous biological information waveforms including an abnormal biological information waveform which is produced initially in abnormal biological information waveforms that are produced in a duration when the abnormal biological information waveforms detected by the analyzing unit are continued and a biological information waveform which is produced just before the production of the initial abnormal biological information waveform, and a second waveform group consisting of continuous biological information waveforms including an abnormal biological information waveform which is last produced and a biological information waveform which is produced just after the production of the last abnormal biological information waveform.
