Integrated Respiratory Gas Sensor Cuvette for Preterm Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory gas flow measuring devices for preterms have a large dead space volume, leading to insufficient fresh air supply and CO2 rebreathing, which can result in life-threatening changes being overlooked due to the omission of certain sensors.
Innovation Solution
A measuring device with a cuvette and multiple sensor units for respiratory gas flow rate, CO2 concentration, and pressure, integrated into a compact design with a low dead space volume, allowing for simultaneous analysis of these parameters without the need for additional connectors, thereby reducing the risk of sensor omission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensor units are connected successively to corresponding connectors and cuvettes, then comprehensive respiratory gas flow analysis can be performed, but the dead space volume is increased considerably
Solution Approach 1:
The patent combines multiple sensor units (flow rate sensor, CO2 sensor, pressure sensor) into a single integrated measuring unit that attaches to one cuvette, eliminating the need for successive connections and reducing dead space volume while maintaining comprehensive analysis capability
Solution Approach 2:
The measuring unit is designed as a universal multi-functional device that can simultaneously measure respiratory gas flow rate, CO2 concentration, and pressure by integrating multiple sensor types into a single unit that interfaces with the cuvette
2Volume of stationary object
If the size of the measuring cuvette is reduced, then the dead space volume is decreased, but the device can only monitor individual sensor units
Solution Approach 1:
Multiple sensor units are merged into a single integrated measuring unit that attaches to one cuvette, allowing comprehensive monitoring (flow rate, CO2, pressure) to be performed simultaneously in a compact configuration with low dead space volume
3Volume of stationary object
If certain sensors are omitted to reduce dead space volume, then the device size is reduced, but life-threatening changes may not be registered
Solution Approach 1:
The patent integrates flow rate, CO2 concentration, and pressure sensors into a single measuring unit that attaches to one cuvette, enabling all necessary sensors to be included without increasing dead space volume, thus maintaining detection of critical changes while keeping the device compact
