Heart-Lung Machine Control Panel Layout for Error-Proof Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current life support systems, such as heart-lung machines, face challenges in intuitive and error-proof operability due to the complexity of multiple medical devices and control elements, which can lead to operational errors and ergonomic issues for healthcare professionals.
Innovation Solution
The life support system features a control panel that protrudes flat over the medical devices, with each device aligned with a dedicated control element and display/monitoring element, ensuring intuitive operation and ergonomic design, allowing for modular configuration and easy maintenance, while the lateral members form a frame to support the devices and facilitate mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple medical devices and control elements are integrated in a compact arrangement, then space requirements are reduced, but operability and clarity of arrangement deteriorate
Solution Approach 1:
The control panel is arranged to protrude essentially flat over the base area of the medical devices in a horizontal plane, creating a layered spatial arrangement. This dimensional organization separates control elements from devices vertically while maintaining horizontal alignment, achieving both compact footprint and clear operational hierarchy.
Solution Approach 2:
The system divides control elements into device-specific segments, with each control element exclusively assigned to operate a specific medical device. This segmentation creates clear functional boundaries and reduces operational complexity despite multiple devices being present.
2Ease of operation
If control elements are assigned to each medical device with aligned arrangement, then operability and error prevention are improved, but device complexity increases
Solution Approach 1:
The control panel protrudes asymmetrically over the base area of the devices, creating a distinct hierarchical structure. This asymmetric arrangement establishes a clear control position that is optimized for operator access while maintaining aligned relationships between control elements and their corresponding devices.
3Ease of operation
If control panel protrudes flat over base area of devices, then ergonomic design and user-friendliness are improved, but manufacturing complexity increases
Solution Approach 1:
The control panel structure serves multiple functions simultaneously: it provides the control interface surface, establishes the ergonomic control position, creates the protruding arrangement over devices, and defines the horizontal alignment relationships. This multi-functionality reduces the need for separate structural components.

AI summary
A life support system such as a heart-lung machine may include a plurality of medical devices a control panel and an excellent control position. The control panel may have separate control elements for operating the medical devices. The control panel may be constructed protruding essentially flat over a floor area of the majority of the medical devices. The control panel may be constructed to protrude in such a manner, that a control element, aligned only with a particular device and with the control position, is assigned to each device.
