Closed Blood Component Transfer System for Sterile Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for filling containers with autologous fresh blood components are complex, unsafe, and non-compliant with hygienic-health regulations due to the risk of external contamination and reliance on skilled personnel and sterile environments.
Innovation Solution
A method utilizing an equipment with a tubular element defining a transit channel with multiple gaps and valve means to create a closed system for filling containers, allowing for sterile and contamination-free transfer of autologous fresh blood components, independent of operator skill and environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual transfer of blood components between containers is performed, then flexibility in preparation is maintained, but contamination risk increases and requires sterile environment and trained personnel
Solution Approach 1:
A closed transfer system with a transit channel acts as an intermediary between the blood component source and final containers, eliminating direct manual handling and external exposure. The system includes a transit channel with valve means that controls blood flow without requiring operator intervention in the sterile field.
Solution Approach 2:
The system enables self-contained blood component transfer where the closed system automatically manages fluid movement through pressure differential creation and valve control, reducing dependence on operator skill and sterile environment maintenance.
2Object-affected harmful factors
If closed system with transit channel is used, then contamination risk is eliminated, but device complexity increases
Solution Approach 1:
The closed system is divided into distinct functional segments: a transit channel for blood flow, valve means for flow control, and connection interfaces for different containers. This segmentation allows each component to perform its specific function while maintaining overall system simplicity.
Solution Approach 2:
The transit channel and valve means serve multiple functions: they control blood flow direction, maintain sterile barriers, enable container filling, and allow system decontamination. This multi-functionality reduces the need for additional complex components.
3Ease of operation
If scissors are used to open dialysis units, then unit opening is achieved, but organic material residues contaminate subsequent units
Solution Approach 1:
The closed transfer system acts as an intermediary that eliminates the need for mechanical cutting tools. Blood components are accessed through sealed ports and transferred via the transit channel, preventing organic material residues on scissors from contaminating subsequent units.
Solution Approach 2:
The system includes self-contained decontamination capabilities where the closed circuit allows for proper disposal and cleaning of components, eliminating cross-contamination risks associated with reusable cutting tools.
