Capnography Fitting With Angled Port for Mask-Seal Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capnography scavenging apparatuses are often fixed to inhalation masks, limiting their adaptability for use by both right- and left-handed users and are cumbersome to reposition, leading to potential seal disruptions and inaccurate readings.
Innovation Solution
A capnography fitting with a first and second tube, featuring an angled port, that allows easy insertion and removal for both right- and left-handed users, compatible with various mask sizes and shapes, providing an air-tight seal and enabling efficient sampling of exhaled gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the capnography scavenging apparatus is fixed to one location on the inhalation mask, then the structure is stable and simple, but it cannot be adapted for both right-handed and left-handed users and cannot obtain optimal readings
Solution Approach 1:
The capnography scavenging apparatus is designed with a movable sampling tube that can be repositioned between different locations on the inhalation mask. The tube can be moved from a first location to a second location, allowing the system to adapt to different user preferences (right-handed or left-handed) while maintaining a relatively simple overall structure. This dynamic repositioning capability resolves the contradiction by providing versatility without requiring multiple fixed apparatuses.
2Adaptability or versatility
If the sampling tube location is changed by manually punching holes into the mask, then the sampling position can be adjusted, but the mask seal is disrupted and gas flow is compromised
Solution Approach 1:
The invention separates the sampling tube from the mask structure, allowing the tube to be positioned at different locations without creating holes in the mask itself. The sampling tube can be inserted through existing openings or positioned to contact the mask surface without compromising the mask's seal integrity. This segmentation allows location adjustment while maintaining the mask's functional integrity and gas flow characteristics.
3Ease of operation
If the sampling tube is fixed in position, then the apparatus structure is simple, but repositioning requires manual hole punching which is time-consuming and cumbersome
Solution Approach 1:
The sampling tube is designed to be movable and repositionable without requiring permanent modifications to the mask. The tube can be easily removed and repositioned to different locations on the mask surface, allowing quick adjustment between right-handed and left-handed configurations. This dynamic design eliminates the time-consuming hole-punching process while maintaining structural simplicity.
