Modular Holding Device for Mobile Heart-Lung Machine Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical perfusion systems for cardiovascular support are too large and cumbersome for safe transport in vehicles and aircraft, posing a risk to patients and crew during transport, especially under acceleration conditions, and are not readily available in rural hospitals.
Innovation Solution
A holding device for a mobile heart-lung machine with a base plate and interchangeable holders for components, including a gas bottle, drive unit, oxygenator, venous bladder trap, and hemofilter, designed for secure fastening in vehicles and aircraft, made of lightweight materials to minimize weight and maximize safety, with features for easy mounting and air bubble prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional perfusion systems are used, then cardiovascular support function is provided, but the systems are too large and unwieldy for safe transport in vehicles and aircraft
Solution Approach 1:
The perfusion system is divided into separate modular components (pump unit, oxygenator, reservoir, gas bottles) that can be individually secured in dedicated holders on the base plate, allowing compact arrangement and safe fixation during transport while maintaining full functionality
Solution Approach 2:
The system transitions from large horizontal floor-standing configurations to a compact vertical wall-mounted arrangement, utilizing vertical space in vehicles and aircraft to reduce the horizontal footprint and enable safe transport in confined spaces
2Strength
If traditional perfusion systems are used, then cardiovascular support is provided, but they pose safety risks under strong positive or negative accelerations in vehicles and aircraft
Solution Approach 1:
Different holders on the base plate are designed with specialized fastening mechanisms suited to specific components: clamping elements for cylindrical gas bottles, bayonet locks for quick connection of blood bags and oxygenators, and secure mounting for the pump unit, with heavier components positioned lower for optimal stability during acceleration
Solution Approach 2:
The fastening mechanisms incorporate quick-release and quick-connect features that allow rapid assembly and disassembly while maintaining secure fixation during transport, enabling dynamic adaptation to different operational phases (transport vs. clinical use)
3Length of moving object
If miniaturized transportable systems are used, then transportability is improved, but availability in rural hospitals needs to be enhanced
Solution Approach 1:
The base plate is designed with universal mounting capabilities that can be installed in various settings (rural hospitals, urban hospitals, ambulances, aircraft), and the modular component system can be configured for different clinical needs (heart-lung support, kidney support, transport), making the system adaptable across diverse environments

AI summary
The invention relates to a holding device for a mobile heart-lung machine, in particular for use in vehicles or aircrafts, which comprises a base plate (15) in which two slots (37) are arranged at a distance from each other. Said slots are used to receive securing means for securing the holding device to securing rails in an aircraft. A first holding element (17) for detachably securing a gas bottle, a second holding element (21) for detachably securing a drive element, and a third holding element (25) for securing an oxgenator are provided on the base plate (15).
