Innovation Solution
The ECMO system lifting device features a support device with a base and vertical column, a lifting device with a support and lifting rod, and guide devices with adjustment mechanisms and guide wheels, ensuring steady and controlled operation by preventing excessive movement and maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the blood pump is affixed at a position as low as possible relative to the patient's heart to ensure sufficient negative pressure drainage, then the blood drainage efficiency is improved, but the convenience of operation during priming deteriorates
Solution Approach 1:
The lifting device is divided into multiple independent lifting rods that can be adjusted separately, allowing the blood pump and membrane lung to be positioned at different heights. This segmentation enables the blood pump to remain at a low position for efficient drainage while the membrane lung can be raised to a convenient operating height during priming.
2Adaptability or versatility
If the conduit is extended to allow frequent patient turning, then the patient position flexibility is improved, but the circulatory resistance and priming volume increase
Solution Approach 1:
The lifting device employs adjustable height mechanisms that allow dynamic repositioning of the blood pump and membrane lung. During patient turning operations, the devices can be raised to higher positions to accommodate the new orientation, and then restored to lower working positions, eliminating the need for excessively long conduits while maintaining patient position flexibility.
3Ease of operation
If the lifting device allows easy adjustment of heights, then the operational convenience is improved, but the risk of accidental operations and single-point failures increases
Solution Approach 1:
The lifting device incorporates safety brake devices that automatically engage to prevent accidental lifting or lowering operations. These brake mechanisms serve as a protective measure in advance, ensuring that even if the lifting rod fails or is accidentally activated, the blood pump and membrane lung will not move abnormally, thereby protecting the patient and equipment.
4Ease of manufacture
If the lifting device operates with simple structure, then the ease of manufacture is improved, but the stability during operation deteriorates
Solution Approach 1:
The lifting device uses multiple independent lifting rods instead of a single complex mechanism. Each rod is a simple, easy-to-manufacture component, but collectively they provide stable and balanced support for the blood pump and membrane lung, ensuring operational stability while maintaining manufacturing simplicity.
