Blood Cassette RFID Data Storage for Transfusion Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In transfusion medicine, there is a high risk of erroneous data transmission during the separation and processing of blood components, leading to incorrect assignment of donor data to blood products, which is difficult to check and correct.
Innovation Solution
A cassette system with a central container connected to outer containers via interruptible means, incorporating a data storage device such as an RFID tag, ensures accurate data transmission and assignment by maintaining a closed system for blood products, and a workstation for marking containers that detects and processes data to prevent errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If repeated transmission of donor data is used during blood component processing, then data can be transferred through multiple processing steps, but the risk of erroneous data transmission increases significantly
Solution Approach 1:
The patent combines the donor data storage directly with the blood product container in a single integrated system. The data carrier is attached to or integrated into the container holding the blood product, ensuring that the data travels with the product throughout all processing steps without requiring separate transmission operations, thereby eliminating errors from repeated data handling.
Solution Approach 2:
The patent creates a permanent copy of the donor data that is physically attached to or integrated with the blood product container. This copy remains with the product through all processing steps, allowing verification at any stage without requiring re-transmission of the original data, thus preventing errors while maintaining processing efficiency.
2Reliability
If manual checking of data transmission is implemented, then data accuracy can be verified, but the processing time and complexity increase significantly
Solution Approach 1:
The system enables self-verification through the permanent association of data with the container. The data carrier remains attached to the blood product container throughout processing, allowing automatic verification at any stage without requiring manual intervention or additional checking steps, thus maintaining both accuracy and efficiency.
3Adaptability or versatility
If separate data transmission steps are used for each processing stage, then data can be updated at each stage, but the complexity of ensuring correct assignment increases
Solution Approach 1:
The patent merges the data storage function with the physical container in a single integrated unit. The data carrier is permanently associated with the blood product container, allowing the system to track and verify data throughout all processing stages without requiring separate data transmission operations or complex data management protocols at each stage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures reliable data transmission and correct assignment of donor data to blood products, preventing errors in labeling and facilitating accurate processing of blood components.
Implementation Method 1
the separation of the individual blood components which is called cell harvesting is effected, as known, by treatment of the blood in a centrifuge. By centrifuging, the individual blood components are separated from each other
