Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring respiratory gases in neonatals require wearable devices or invasive equipment, which can be obstructed or impractical for continuous and accurate measurement, especially in an incubator setting.
Innovation Solution
A contactless gas monitoring system with sampling channels integrated into the incubator mattress or walls, allowing for multiple sampling points around the neonatal's head, connected to a monitoring unit for continuous and accurate CO2 level monitoring without the need for wearable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If masks, nasal prongs or wearable devices are used to monitor CO2 levels in neonatals, then CO2 monitoring can be performed, but the devices can be obstructed by the neonatal or equipment within the incubator, reducing reliability
Solution Approach 1:
The invention extracts the gas sampling function from wearable devices (masks, nasal prongs) and integrates it directly into the incubator structure through sampling ports and channels. This removes the obstruction problem by eliminating movable wearable components that can be displaced or blocked, while maintaining the ability to monitor CO2 levels in the incubator environment.
Solution Approach 2:
The invention introduces sampling ports and sampling channels as intermediary structures between the incubator interior and the CO2 monitoring system. These intermediaries enable contactless gas sampling by transporting CO2-containing air from the neonatal's breathing zone to external sensors, avoiding direct contact with the neonatal while ensuring reliable measurement.
2Ease of operation
If a single sampling point is used in the incubator, then the system is simple, but it cannot provide uniform monitoring when the neonatal moves position
Solution Approach 1:
The invention segments the single sampling function into multiple sampling ports distributed at different locations and elevations within the incubator. This segmentation allows the system to maintain simplicity in each individual sampling point while achieving comprehensive and uniform monitoring coverage through the collective contribution of multiple sampling points, regardless of neonatal position.
3Measurement precision
If sampling ports are placed at various locations and elevations, then uniform monitoring is achieved, but the device complexity increases
Solution Approach 1:
The invention applies universality by designing sampling ports and channels that serve multiple functions: they enable contactless gas sampling, provide spatial distribution for uniform monitoring, and can be integrated into the incubator's existing structure. This multi-functionality reduces overall system complexity despite the presence of multiple sampling points, as the same structural elements fulfill several monitoring requirements simultaneously.

Function Achieved in This Case
Enables continuous, accurate, and uniform monitoring of CO2 levels, even when the neonatal moves, by forming a sampling array that adapts to the neonatal's position, providing better results and minimizing obstruction risks.
