Heart-lung machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heart-lung machines with multiple medical devices face challenges in intuitive operation and ergonomics, leading to potential errors and health issues for operators due to complex designs and lack of user-friendly interfaces.
Innovation Solution
The heart-lung machine is designed with an operating panel where each device is aligned with its corresponding operating element, creating a clear and intuitive operating position, and incorporating a modular structure with display and control elements to ensure error-free and ergonomic operation, allowing operators to easily access and understand the status of medical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple medical devices are integrated into a single heart-lung machine system, then the functionality and versatility of the system is improved, but the device complexity and operational clarity deteriorate
Solution Approach 1:
The control panel is segmented into separate control elements, each dedicated to a specific medical device (oxygenator, heat exchanger, blood pumps). This segmentation allows each device to have its own dedicated controls and display area, reducing operational complexity while maintaining the integrated functionality of multiple devices in a single system.
2Volume of stationary object
If the medical devices are arranged compactly to save space, then the volume restriction is improved, but the intuitive assignment of control elements to devices deteriorates
Solution Approach 1:
The system uses vertical arrangement in another dimension to achieve compact footprint while maintaining intuitive control-device association. Devices are stacked vertically with their control elements arranged in corresponding vertical positions on the control panel, allowing compact spatial arrangement without sacrificing the intuitive mapping between controls and devices.
