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 is of actual value during intubation procedures.
Innovation Solution
A laryngoscope with a grip sensor that initiates and continues recording only when the handle is gripped by the operator, 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 continuous recording from power-on to power-off is implemented, then complete documentation of the procedure is achieved, but file size and memory requirements increase significantly
Solution Approach 1:
The system performs preliminary actions by buffering video data in memory before the actual recording trigger event occurs. When the intubation event is detected (via grip sensor activation), the system has already captured and buffered the relevant data in readiness, allowing immediate recording without starting from power-on. This preliminary buffering approach ensures complete documentation of the critical event while avoiding recording of unnecessary pre-event data.
Solution Approach 2:
The system extracts only the essential portion of the video data stream that contains the intubation event. By using the grip sensor trigger to identify and extract only the relevant time window (from trigger to tube confirmation), the system separates valuable procedural data from unnecessary surrounding data, significantly reducing file size while maintaining complete documentation of the critical event.

Solution Approach 2:
The system applies different recording quality and activation characteristics to different time periods. Instead of uniform continuous recording, the system activates high-quality recording only during the critical intubation event window (when the grip sensor is triggered), while using lower-resolution preview mode before and after. This local quality adjustment ensures complete documentation of the critical event while minimizing privacy exposure during non-critical 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.
