Solution Overview
Problem
Current cardiopulmonary bypass systems have large, horizontal support structures that occupy excessive space and impede healthcare professional movement, require manual calibration of peristaltic pumps, leading to inefficiencies and potential errors due to incorrect adjustments.
Innovation Solution
A vertically configured system with integrated, easily replaceable peristaltic pumps and a control unit for automated monitoring and control, reducing the need for manual adjustments and minimizing space requirements, while allowing for precise calibration and error reduction through pre-calibrated rotor elements and integrated sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a substantially horizontal support structure is used, then the system can support peristaltic pumps and infusion circuits, but it occupies excessive space and impedes healthcare professional movement
Solution Approach 1:
The patent transitions from a horizontal support structure to a substantially vertical support structure. This dimensional change reduces the horizontal footprint and space occupation while maintaining the functional capability to support pumps and circuits, thereby improving healthcare professional movement around the system.
2Adaptability or versatility
If manual calibration of peristaltic pump rotor lobes is performed, then the system can be adjusted to different tube types, but it consumes excessive time and introduces potential errors
Solution Approach 1:
The patent implements pre-calibrated rotor elements that are manufactured with predetermined lobe positions optimized for specific tube cross-sections. This preliminary calibration during manufacturing eliminates the need for time-consuming manual adjustment during clinical use, while maintaining full adaptability to different tube types through selection of appropriate pre-calibrated rotors.
Solution Approach 2:
The patent employs disposable rotor elements that are pre-calibrated for specific tube types. These single-use rotors eliminate the need for repeated manual calibration and ensure consistent performance without the risk of calibration drift or error accumulation from repeated adjustments.
3Adaptability or versatility
If manual calibration of peristaltic pump rotor lobes is performed, then adjustment to tube types is possible, but it requires highly qualified personnel and introduces margins of error
Solution Approach 1:
The patent implements pre-calibrated rotor elements that are manufactured with predetermined lobe positions optimized for specific tube cross-sections. This preliminary calibration during manufacturing eliminates the need for time-consuming manual adjustment during clinical use, while maintaining full adaptability to different tube types through selection of appropriate pre-calibrated rotors.
Solution Approach 2:
The system includes automated detection capabilities that identify the tube type and automatically select or adjust the appropriate rotor configuration without requiring manual intervention by qualified personnel. This self-service approach eliminates human error in calibration while maintaining adaptability to different tube types.
4Area of stationary object
If a vertical support structure is implemented, then space occupation is reduced and movement is facilitated, but the system configuration becomes more complex
Solution Approach 1:
The patent transitions from a horizontal support structure to a substantially vertical support structure. This dimensional change reduces the horizontal footprint and space occupation while maintaining the functional capability to support pumps and circuits, thereby improving healthcare professional movement around the system.
