Swallowing Videoendoscopy Processor Timing Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current swallowing videoendoscopy systems face challenges in accurately diagnosing dysphagia due to the complexity and speed of the swallowing reflex, making it difficult to determine the appropriate timings for swallowing instruction, inflow of the object into the pharynx, and triggering of the swallowing reflex.
Innovation Solution
An examination device and method that utilize a processor to detect at least two critical timings during swallowing videoendoscopy: the swallowing instruction timing, the inflow timing of the object into the pharynx, and the swallowing reflex triggering timing, allowing for the determination of dysphagia based on these timings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If normal playback of recorded swallowing video is used for diagnosis, then the diagnostic process is simple, but the diagnostic accuracy is insufficient due to the fast speed of swallowing reflex
Solution Approach 1:
The system performs preliminary detection and marking of critical timing points (swallowing instruction timing, inflow timing, reflex triggering timing) during video recording. This allows the diagnostician to later review only the marked segments with known critical events, rather than reviewing the entire video or relying on slow frame-by-frame playback, thus maintaining operational simplicity while improving diagnostic accuracy.
2Measurement precision
If frame-by-frame playback is used to improve diagnostic accuracy, then diagnostic precision improves, but the time required for diagnosis increases significantly
Solution Approach 1:
The system pre-detects and marks critical timing points during video acquisition, so that during diagnosis, the clinician can directly jump to and review only the marked critical segments. This eliminates the need for time-consuming frame-by-frame playback of entire videos while maintaining high diagnostic accuracy through focused review of predetermined critical moments.
Solution Approach 2:
The swallowing video is segmented into critical segments based on detected timing points (swallowing instruction, inflow, reflex triggering). Instead of reviewing the entire continuous video or using slow frame-by-frame playback, the system divides the video into discrete, clinically relevant segments that can be reviewed efficiently, reducing diagnosis time while maintaining accuracy.
3Loss of information
If multiple timing detection parameters are measured, then diagnostic information completeness improves, but the system complexity increases
Solution Approach 1:
The processor is designed to perform multiple detection functions (detecting swallowing instruction timing, inflow timing, and reflex triggering timing) using a unified timing detection mechanism. This multi-functional approach allows comprehensive diagnostic information collection without proportionally increasing system complexity, as the same core detection infrastructure serves multiple diagnostic purposes.
Solution Approach 2:
The system combines multiple timing detection parameters (swallowing instruction timing, inflow timing, reflex triggering timing) into a single integrated detection and analysis process. By merging these detection functions into one coordinated system rather than separate independent systems, the complexity is minimized while still capturing complete diagnostic information across all critical swallowing phases.

AI summary
An examination device includes a processor, and the processor detects, in swallowing videoendoscopy in which an inflow object is given to a subject and a swallowing action is observed, at least two timings among a swallowing instruction timing at which a swallowing instruction is given, an inflow timing of the inflow object into the pharynx during the swallowing action, and a swallowing reflex triggering timing in the subject.
