Video Laryngoscope Training Mode with Obscured Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical professionals face challenges in maintaining direct laryngoscopy skills due to the integration of video laryngoscope displays, which can be obstructed by poor lighting and excess blade curvature, and there is no standardized clinical practice for visualization during intubation, leading to a need for a training mode that allows practice and maintenance of direct laryngoscopy skills using a video laryngoscope.
Innovation Solution
A direct laryngoscope training mode for video laryngoscopes that obscures acquired images on the integrated display, allowing them to be displayed unobscured on an external screen, with adjustable light brightness and the option to record and label training sessions, enabling practitioners to practice direct laryngoscopy skills while maintaining video laryngoscopy functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the video laryngoscope display is integrated into the line-of-sight of the operator, then real-time visualization of the larynx is facilitated, but direct laryngoscopy skills deteriorate due to obstruction by poor lighting and excess blade curvature
Solution Approach 1:
The system dynamically switches between video laryngoscopy mode and direct laryngoscopy training mode. In training mode, the integrated display is obscured to force the operator to rely on direct visualization through the blade, while in video mode the display is fully functional. This dynamic adaptation allows the same device to serve both purposes effectively.
Solution Approach 2:
The display functionality is segmented into two distinct modes: video laryngoscopy mode with full display visibility and direct laryngoscopy training mode with obscured display. This segmentation allows the system to provide specialized functionality for each mode without compromise, enabling skill maintenance in direct laryngoscopy while preserving video capabilities.
2Loss of information
If the integrated display is made prominent for video laryngoscopy, then indirect visualization is improved, but direct laryngoscopy training capability deteriorates
Solution Approach 1:
The display obscuration is dynamically controlled based on the selected mode. A processor receives mode selection input and dynamically adjusts the display state - either showing the video feed clearly in video mode or obscuring it in direct laryngoscopy training mode. This dynamic control enables the display to facilitate video laryngoscopy when needed while not interfering with direct laryngoscopy training.
3Adaptability or versatility
If the video laryngoscope is used for direct laryngoscopy training, then skill maintenance is improved, but the lighting conditions deteriorate due to excess blade curvature blocking light
Solution Approach 1:
The system changes the lighting parameter by providing both illuminated and non-illuminated training modes. In non-illuminated mode, the light source is turned off or reduced to simulate poor lighting conditions that match real direct laryngoscopy scenarios. In illuminated mode, the light source provides adequate illumination. This parameter change allows realistic training conditions while maintaining the ability to provide adequate lighting when needed.

AI summary
A training mode for a video laryngoscope is disclosed. The training mode may allow an operator to practice and maintain DL skills with a video laryngoscope. In the training mode, a video image typically provided on an integrated display of the video laryngoscope may be temporarily obscured, filtered, or turned off. Additionally, the unfiltered video image acquired by the video laryngoscope may be displayed on an external display, separate from the video laryngoscope. The external display may be viewable by a trainer (e.g., an attending) for teaching purposes. The training mode may also include an adjustment of a brightness and/or intensity of a light source on the video laryngoscope (e.g., a light source may be brighter/more intense during training mode than during normal video laryngoscopy). In an instance where the video is recorded, at least a portion of the recording that is associated with the training mode may be labeled.
