Conduit Clamping Mechanism for Closed-Tube Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedures for removing and managing fluid accumulations below the skin, such as after surgery, are cumbersome, often require multiple personnel, and pose risks of incomplete drainage and infection due to the complexity of existing conduit clamping devices and handling of open vessels.
Innovation Solution
A conduit clamping device with a closing mechanism featuring a movable arm or disk connected to a knob, allowing for easy control of fluid or air passage in a flexible conduit, which can be integrated into medical apparatus for single-person operation, reducing the risk of backflow and infection by maintaining a closed system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional conduit clamping devices are used, then fluid passage can be controlled, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The conduit clamping device is divided into distinct functional segments: a closure member that directly occludes the conduit, a control mechanism that actuates the closure member, and a actuation mechanism that transmits force. This segmentation allows each component to be optimized independently, reducing overall complexity while maintaining operational effectiveness.
Solution Approach 2:
The invention extracts the essential function of conduit closure from complex multi-component systems and implements it through a simplified mechanism. The closure member is designed to perform the primary occlusion function with minimal additional components, removing unnecessary complexity from the overall device while preserving the ability to control fluid passage.
2Productivity
If multiple personnel are used for fluid removal, then complete drainage is achieved, but productivity decreases and time consumption increases
Solution Approach 1:
The conduit clamping device is designed to be self-operating once activated. The control mechanism and actuation mechanism work automatically to occlude the conduit without requiring continuous manual intervention or coordination between multiple personnel. This self-service capability enables a single operator to achieve complete drainage efficiently, significantly improving productivity and reducing time consumption compared to conventional methods requiring multiple persons.
3Reliability
If open vessels are used for fluid collection, then fluid can be collected, but the risk of infection and backflow increases
Solution Approach 1:
The invention introduces a closed collection system that acts as an intermediary between the conduit and the external environment. This closed system maintains fluid containment throughout the collection process, eliminating the need for open vessels and the associated infection risks. The system allows complete drainage to be achieved by a single operator through controlled actuation, maintaining ease of operation while significantly improving reliability by preventing contamination and backflow.
