Blood Separation Device Adaptive Procedure Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blood separation systems lack flexibility in adapting to individual donor characteristics, potentially leading to suboptimal procedures that may not maximize donor comfort or efficiency in blood component collection.
Innovation Solution
A blood separation device and method that assesses the suitability of a blood source for different versions of a blood separation procedure, allowing for the selection between a 'standard' and 'introductory' version based on donor-specific factors such as age, weight, and blood draw history, to optimize the separation efficiency and donor tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single blood separation procedure is used for all donors, then the device complexity is reduced, but the adaptability to individual donor characteristics deteriorates
Solution Approach 1:
The system dynamically selects between different procedure versions (standard and introductory) based on real-time assessment of donor characteristics such as age, weight, and blood draw history. The controller adjusts procedural parameters including blood draw rate, fluid volumes, and separation settings to optimize for each donor's tolerance and efficiency, transforming a static single procedure into a dynamic adaptive system.
2Productivity
If a standard blood separation procedure is used, then the separation efficiency is maximized, but the donor comfort deteriorates
Solution Approach 1:
The system modifies key procedural parameters based on donor assessment results. For introductory procedures, it reduces blood draw rates, adjusts fluid volumes, and modifies separation settings compared to standard procedures. These parameter changes maintain adequate collection efficiency while reducing physiological stress and discomfort for vulnerable donors.
3Object-affected harmful factors
If different procedure versions are implemented, then the donor comfort is improved, but the device complexity increases
Solution Approach 1:
The system performs self-assessment of donor suitability by automatically evaluating entered donor characteristics (age, weight, blood draw history) against predefined criteria. The controller autonomously determines whether to implement standard or introductory procedures without requiring manual classification, reducing operational complexity while maintaining improved donor comfort through appropriate procedure selection.

Data Source
AI summary
A blood separation device has a controller configured to execute a first and a second version of a blood separation procedure. Information regarding a blood source is analyzed to determine whether to implement the first version of the procedure or the second version. This may include an analysis of the age, weight, and/or sex of the blood source, along with whether the blood source has previously been the subject of a blood separation procedure. The second version may allow for a greater percentage of the blood or red blood cells of the blood source to be outside of the body of the blood source (in a fluid flow circuit mounted to the device) at any time during the procedure. The second version may also or alternatively allow for a higher blood cell separation efficiency than the first version, along with separating the blood in a larger blood separation chamber.
