Oxygen Facemask Lateral Sampling Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxygen-delivering facemasks and nasal cannulas lack a universal, easy-to-use design that can effectively deliver oxygen and sample exhaled gases in various clinical scenarios, particularly struggling with accessibility and interference from oxygen delivery lines.
Innovation Solution
A facemask with two lateral sampling ports positioned away from the oxygen inlet, allowing for easier access and sampling of exhaled gases, along with a breathing mask system that includes a sensor to detect carbon dioxide levels and an alarm for threshold alerts, facilitating use in diverse clinical settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sampling ports are positioned near the oxygen inlet, then gas sampling is easier, but oxygen delivery lines interfere with sampling access
Solution Approach 1:
The sampling ports are extracted from the traditional location near the oxygen inlet and repositioned to lateral positions on the mask. This separation removes the interference caused by oxygen delivery lines while maintaining ease of access for sampling operations.
Solution Approach 2:
The sampling ports are positioned in a different spatial dimension (laterally on the mask sides) rather than centrally near the oxygen inlet. This dimensional repositioning allows simultaneous access to both oxygen delivery and gas sampling without interference.
2Adaptability or versatility
If multiple sampling ports are added to the mask, then gas sampling versatility improves, but device complexity increases
Solution Approach 1:
The mask is designed with multiple sampling ports that can serve different functions - one port can be used for capnography monitoring while another can be used for other gas analysis purposes. This multi-functionality increases versatility without requiring separate devices.
Solution Approach 2:
The sampling function is segmented into multiple independent ports, allowing each port to be used for specific monitoring purposes. This segmentation enables versatile gas sampling while keeping each individual port simple in design.
3Device complexity
If sampling ports are positioned centrally on the mask, then structural simplicity is maintained, but accessibility for sampling is reduced
Solution Approach 1:
Instead of symmetric central positioning, the sampling ports are positioned asymmetrically on the lateral sides of the mask. This asymmetric positioning improves accessibility for sampling operations while maintaining relatively simple mask structure.
