Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intubation devices face challenges in accurately positioning the tube within the trachea, risking injury and improper ventilation, especially during emergencies, and the timing of air delivery during assisted ventilation can interfere with chest compressions, reducing their effectiveness.
Innovation Solution
A ventilation device with a pressure lumen and control system that detects pressure changes in the body passageway to optimize the timing and volume of air delivery, ensuring proper placement and enhancing the efficiency of chest compressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional intubation devices are used with manual placement, then the device can be positioned in the airway, but the risk of misplacement into the esophagus and injury to vocal cords increases
Solution Approach 1:
The patent incorporates sensors that detect pressure changes, movement, and other parameters during insertion to provide real-time feedback to the operator. This feedback mechanism enables the system to detect when the tube has been properly positioned in the trachea versus the esophagus, allowing for immediate correction and reducing misplacement risks.
Solution Approach 2:
The patent replaces purely manual mechanical placement with an automated or semi-automated positioning system that uses sensors, actuators, and control algorithms. This substitution reduces reliance on operator skill and intuition, thereby minimizing the risk of injury to vocal cords and misplacement.
2Productivity
If air is delivered during chest compressions for assisted ventilation, then ventilation can be provided, but the timing may interfere with chest compression effectiveness
Solution Approach 1:
The patent employs a control system that dynamically adjusts the timing of air delivery based on real-time detection of chest compression phases. The system synchronizes ventilation with the compression cycle, delivering air during appropriate phases to maximize ventilation effectiveness while minimizing interference with compression efficacy.
Solution Approach 2:
The system uses sensors to continuously monitor chest compression characteristics and feedback this information to the control system. This feedback loop enables automatic timing adjustment of air delivery to optimize both ventilation and chest compression effectiveness simultaneously.
