Modular Biomedical Device Support Appliance for Extracorporeal Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing appliances for supporting biomedical devices, such as oxygenators and pumping assemblies, are not easily movable or adaptable to specific needs during extracorporeal circulation, particularly in non-hospital emergency situations, and fail to facilitate optimal positioning and fluid dynamics.
Innovation Solution
A portable appliance with a load-bearing body, command and control unit, and a holding element with removable supporting means allows for flexible positioning and movement of oxygenators and pumping assemblies, enabling separate handling and optimal fluid dynamics during extracorporeal circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed supporting appliance is used for oxygenator and pumping assembly, then the devices can be supported stably, but the appliance cannot be easily moved or adapted to specific needs in different environments
Solution Approach 1:
The supporting appliance is divided into separate modular components: a base unit, a holding element, and removable supporting means. This segmentation allows each component to be independently positioned, moved, or adjusted, enabling the system to adapt to different environmental requirements while maintaining stability during operation.
Solution Approach 2:
The appliance incorporates dynamic elements including adjustable supporting means that can be positioned at different locations on the holding element, and a command and control unit that can dynamically adjust operational parameters. This dynamic capability allows the system to adapt to changing requirements during extracorporeal circulation procedures.
2Ease of operation
If the oxygenator and pumping assembly are fixed in position, then stable support is provided, but the ability to change positions relative to the patient and other medical devices is limited
Solution Approach 1:
The supporting means are separated into distinct components that can be independently positioned on the holding element. This segmentation simplifies the positioning process, as each component can be adjusted separately to achieve optimal configuration without requiring complex integrated positioning mechanisms.
Solution Approach 2:
The holding element is designed with multiple attachment points and a universal structure that can accommodate different configurations of oxygenator and pumping assembly. This multi-functionality allows the same base unit to support various device arrangements depending on patient position and procedural requirements.
3Adaptability or versatility
If separate supporting means are used for oxygenator and pumping assembly, then flexible positioning is achieved, but the structural complexity of the supporting appliance increases
Solution Approach 1:
The separate supporting means for the oxygenator and pumping assembly are integrated onto a single holding element structure. This merging approach provides the flexibility of separate positioning while avoiding the structural complexity of two completely independent support systems, as both devices share the common holding element and base unit.
