Insufflation Device Bypass for Effluent Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas insufflation devices for intestinal exploration face contamination and inefficiency in effluent collection, as they use the same passage for gas insufflation and effluent collection, leading to distorted images during diagnostic procedures due to residual effluents and increased pressure that contaminates the device.
Innovation Solution
The device incorporates a bypass system with a second gas evacuation duct to manage excess pressure and separate gas and effluent pathways, ensuring gas is released externally and effluents are collected independently, with antiviral and antibacterial barriers and a hydrophobic filter to maintain hygiene and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same duct is used for both gas insufflation and effluent collection, then the device structure is simpler, but the insufflation device becomes contaminated by effluents and gases from the cavity
Solution Approach 1:
The single duct is divided into two separate ducts: a first duct for gas insufflation and a second duct for effluent collection. This segmentation prevents cross-contamination between the insufflation device and the cavity effluents, while maintaining relatively simple overall device structure.
Solution Approach 2:
The effluent collection function is extracted from the gas insufflation duct and placed into a separate second duct. This extraction eliminates the harmful contamination effect on the insufflation device while preserving the simplicity of the device structure.
2Object-affected harmful factors
If barriers are inserted in the first duct to prevent effluent passage, then device contamination is reduced, but effluent collection is incomplete due to gas current interference
Solution Approach 1:
By separating effluent collection into a dedicated second duct, the system eliminates the interference between gas current and effluent flow that occurs in a single duct system. This allows complete effluent collection without compromising device protection.
Solution Approach 2:
The effluent collection function is extracted from the gas insufflation path and placed in a separate second duct, removing the harmful interaction between insufflated gas and effluent flow that prevents complete collection.
3Reliability
If the insufflation device supports excess pressure during diagnosis, then the device can handle pressure variations, but the device becomes contaminated by absorbing gases from the cavity
Solution Approach 1:
The second duct is extracted as a separate pressure relief pathway that does not connect to the insufflation device. This allows the device to handle pressure variations reliably while preventing contamination, as the pressure relief function is separated from the gas supply function.
Solution Approach 2:
The second duct acts as an intermediary pathway for excess pressure and gases, providing a safe outlet that protects the insufflation device from contamination while maintaining the device's ability to handle pressure variations.
4Ease of operation
If effluents remain in the rectal cavity due to incomplete collection, then the single duct system is simpler to operate, but diagnostic image quality is considerably hampered
Solution Approach 1:
The separation into two dedicated ducts maintains ease of operation while achieving complete effluent collection, as each duct has a single clear function that simplifies the operational logic despite the increased structural complexity.
