Laryngoscope Grip Sensor for Targeted Video Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video laryngoscopes record excessive data, increasing file size, memory requirements, and privacy concerns, while only a small portion of the data is of value during intubation procedures.
Innovation Solution
A laryngoscope with a grip sensor that initiates and continues recording only when the operator's hand is gripping the handle, using a capture device and non-volatile memory to store relevant data, reducing unnecessary data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video laryngoscopes record the entire data stream from power-on to power-off, then complete procedural documentation is achieved, but file size and memory requirements increase significantly
Solution Approach 1:
The system performs preliminary actions by detecting handle grip events and preparing to record only when the operator actually uses the device, rather than recording continuously from power-on. This anticipatory detection mechanism ensures that recording is triggered only when clinically relevant data is being captured, eliminating unnecessary pre-procedure recording time.
Solution Approach 2:
The system extracts and isolates only the clinically relevant portions of the data stream by using grip detection to identify when the operator is actively using the laryngoscope. By separating useful recording intervals from unnecessary ones, the system captures only the essential procedural moments while discarding extraneous data.
2Loss of information
If video laryngoscopes record the entire data stream, then no data is missed, but data transfer and review time increase
Solution Approach 1:
The grip detection mechanism performs preliminary identification of relevant recording intervals, allowing the system to prepare and capture data only during actual procedural use. This eliminates the need to transfer and review entire continuous recordings, significantly reducing post-procedure data processing time while ensuring no critical moments are missed.
Solution Approach 2:
The system applies partial recording action by capturing data during identified grip intervals rather than continuous recording. This partial approach is sufficient to capture all essential procedural information while dramatically reducing the total data volume requiring transfer and review.
3Reliability
If video laryngoscopes record the entire data stream, then comprehensive documentation is achieved, but privacy concerns increase
Solution Approach 1:
The system extracts and removes private or sensitive information from the recorded data by limiting capture to only those intervals when the device is actively being used for its intended medical purpose. This extraction approach ensures that incidental or private moments outside actual procedural use are not captured, reducing privacy exposure while maintaining comprehensive procedural documentation.
Solution Approach 2:
The system applies different recording quality levels to different time intervals - full recording during active procedural intervals (when grip is detected) and no recording during inactive intervals. This local differentiation ensures comprehensive documentation of medical procedures while protecting privacy during non-procedural periods.

AI summary
Disclosed are embodiments of a laryngoscope that facilitates targeted recording (video, or audio, or both video and audio) of time intervals associated with active laryngoscopy. In accordance with the teachings of the disclosure, a characteristic that reliably defines the interval of active laryngoscopy is used to trigger recording. One such characteristic is that the operator's hand is gripping the handle of the laryngoscope. Accordingly, preferred embodiments implement a laryngoscope having a handle so designed that when the handle is gripped by the operator's hand, recording is initiated and continued for as long as the operator's hand maintains a grip on the laryngoscope handle.
