Cable Chase Routing for Cardiopulmonary Bypass Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rearrangement and management of peripheral modules in cardiopulmonary bypass systems, such as heart-lung machines, are inefficient due to the complex interweaving of cables and conduits, leading to operational inconvenience and increased downtime during surgical procedures.
Innovation Solution
A cardiopulmonary bypass system with a cable chase that encloses a channel for receiving cables or conduits, featuring apertures for entry and exit at different locations and a reversible cover for access control, allowing for improved routing and management of cables, and attachment to the machine's frame and base for enhanced reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peripheral modules are rearranged or replaced during surgical procedures, then operational flexibility and adaptability are improved, but cable management complexity increases and downtime increases
Solution Approach 1:
The system divides the cable management function into separate cable chases associated with each peripheral module. Each cable chase is an independent enclosure that can be accessed, modified, or removed without affecting other modules, enabling quick replacement while maintaining cable organization.
Solution Approach 2:
Cable chases act as intermediary structures between peripheral modules and the main console. These chases provide dedicated pathways and enclosures for cables, serving as mediating elements that facilitate module replacement while managing cable complexity.
2Adaptability or versatility
If multiple cables and conduits are routed through the system, then connectivity and functionality are improved, but cable clutter and management difficulty increase
Solution Approach 1:
The cable management system is segmented into multiple dedicated cable chases, one for each peripheral module. Each cable chase provides a separate enclosed pathway, preventing cable interweaving and clutter while maintaining all necessary connections.
Solution Approach 2:
Cables and conduits are nested within the enclosed spaces of cable chases. The cable chases themselves are nested within or attached to the peripheral modules and main console structure, creating organized hierarchical routing.
3Productivity
If peripheral modules are quickly replaced, then productivity is improved, but cable routing complexity must be reduced
Solution Approach 1:
By segmenting cable management into module-specific cable chases, the system enables quick module replacement without requiring complex cable rerouting. Each module's cables remain organized in its own enclosed space, allowing immediate swapout.
Solution Approach 2:
Cable chases are pre-configured and pre-routed during system assembly. This preliminary organization of cables before the surgical procedure eliminates the need for complex cable management during module replacement, enabling faster productivity.

AI summary
A cardiopulmonary bypass system comprises: a cardiopulmonary bypass machine comprising a console, the console comprising a base and a frame connected to the base; a plurality of peripheral modules operatively connectable to the cardiopulmonary bypass machine; and a cable chase comprising a first end and a second end, and a cable chase housing that extends at least partially between the first end and second end and at least partially encloses a channel for receiving one or more cables or conduits connected to at least one of the plurality of peripheral modules, wherein the base comprises a console pump support surface for supporting a plurality of console pumps, and wherein the frame comprises a shelf that is elevated with respect to the console pump support surface, and wherein the channel is configured to attach to one or both of the base and the frame, and wherein a cable holder is suspended from an underside of the shelf and comprises a plurality of fingers extending upwards from a channel body to provide for one or more passages for cables or conduits to be secured underneath the shelf.
