Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ventilation systems lack an effective method to adequately adjust and coordinate ventilation and stimulation based on the work of breathing performed by patients, leading to inadequate support for respiratory muscles, which can result in lung damage and inefficient breathing assistance.
Innovation Solution
A device and process that utilize electromyographic signals to determine the state of respiratory muscles, allowing for synchronized and proportional ventilatory assistance, adjusting ventilation parameters to match the patient's muscle activation and load-bearing capacity, and providing stimulative support to optimize breathing efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ventilation systems provide fixed mechanical support without adjusting to patient's muscle activation, then mechanical ventilation can be maintained, but respiratory muscle atrophy and lung damage occur
Solution Approach 1:
The ventilation system dynamically adjusts mechanical support based on real-time detection of patient's respiratory muscle activation signals (EMG). The level of ventilatory assistance is continuously modified according to the detected muscle activation level, transitioning from fixed to adaptive support that responds to patient's actual respiratory needs and muscle capacity.
Solution Approach 2:
The system implements feedback control by detecting the patient's respiratory muscle activation signals and using this information to adjust the ventilatory assistance level. The detection unit monitors muscle activation continuously, and the control unit modifies ventilation parameters based on this feedback, creating a closed-loop system that prevents muscle atrophy while maintaining adequate ventilation.
2Productivity
If ventilation systems increase mechanical support to ensure adequate breathing, then breathing assistance is improved, but respiratory muscle load-bearing capacity deteriorates
Solution Approach 1:
The system dynamically balances mechanical support and muscle loading by continuously adjusting ventilation assistance according to detected muscle activation. When muscle activation indicates sufficient capacity, mechanical support is reduced to maintain muscle strength. When activation signals indicate fatigue or insufficient capacity, mechanical support is increased to ensure adequate breathing while preserving muscle load-bearing capacity.
3Reliability
If ventilation systems provide continuous mechanical ventilation, then patient breathing is maintained, but patient's spontaneous breathing effort and muscle activation decrease
Solution Approach 1:
The system uses feedback from detected muscle activation signals to modulate mechanical ventilation levels. When spontaneous muscle activation is detected, the system reduces mechanical support to allow and encourage further spontaneous effort. When activation is insufficient, mechanical support is increased to maintain breathing while gradually weaning as capacity improves.
