Catheter Mount Suction Port Valve for Respiratory Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catheter mounts in respiratory assistance systems do not provide easy access to the components between the catheter mount and the ventilator, making it difficult to suction condensate and secretions from the intermediate tube.
Innovation Solution
A catheter mount with multiple ports in fluid communication, including an interface port, a conduit port, and a suction port, where the suction port is equipped with a valve allowing direct access to both the interface and conduit tubes, facilitating easy suctioning of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional catheter mount is used with a sealed passageway, then the system maintains sealing integrity, but access to components between the catheter mount and ventilator becomes difficult
Solution Approach 1:
The catheter mount is segmented into multiple functional ports: an interface port for connecting to the interface tube, a conduit port for the conduit tube, and a suction port for the suction catheter. This segmentation allows independent access to different components while maintaining the overall sealed structure, resolving the contradiction between ease of access and structural integrity.
Solution Approach 2:
The suction port acts as an intermediary access point that enables the suction catheter to reach components between the catheter mount and ventilator without compromising the sealed passageway. This intermediary structure facilitates maintenance access while preserving the integrity of the main connection pathways.
2Ease of operation
If a suction catheter needs to access both interface tube and conduit tube, then comprehensive cleaning is achieved, but the time required for maintenance increases
Solution Approach 1:
The suction port is designed with multi-functionality to provide access to both the interface tube and conduit tube through a single entry point. The valve mechanism within the suction port can be configured to direct the suction catheter to either tube, eliminating the need for separate access points and reducing maintenance time while ensuring comprehensive cleaning of all components.
3Adaptability or versatility
If multiple ports are added to the catheter mount, then access to different tubes is facilitated, but the device structure becomes more complex
Solution Approach 1:
Multiple access functions are merged into a single suction port through the use of an internal valve mechanism. This valve allows the suction catheter to be directed to either the interface tube or conduit tube, combining what would otherwise require separate ports into one integrated structure, thereby maintaining versatility while minimizing structural complexity.
