Integrated Blood Collection and Testing Bag System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blood transfusion methods are prone to blood group incompatibilities and bacterial contamination due to the separation of test tubes and connection tubes during the blood grouping process, leading to potential errors and risks.
Innovation Solution
A biomedical container system comprising a collection blood-bag and a test blood-bag mechanically and fluidically connected via a robust connection line, ensuring that the blood or blood component tested is the same as the one collected, with integrated test kits for accurate blood grouping and bacterial testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If blood grouping is performed using separate test tubes and connection tubes that are physically separated from the blood bag, then the blood bag can be welded and processed independently, but accidental exchange or mistaken identification of tubes can occur leading to blood group typing errors
Solution Approach 1:
The patent merges the test tube and connection tube into a single integrated test blood-bag that remains fluidically connected to the collection blood-bag throughout the process. This eliminates the need to physically separate and rejoin components, preventing tube exchange errors while maintaining the ability to weld and process the collection blood-bag independently.
Solution Approach 2:
The patent introduces a mechanical connection line as an intermediary element that provides a robust, error-proof connection between the collection blood-bag and test blood-bag. This intermediary mechanism prevents accidental disconnection or exchange while allowing independent handling and welding of the collection blood-bag.
2Ease of operation
If multiple manual operations are performed for blood sampling, tube separation, and testing, then flexible handling is possible, but the risk of accidental tube exchange and human error increases
Solution Approach 1:
The patent combines the collection and testing functions into an integrated system where the test blood-bag remains connected to the collection blood-bag. This reduces the number of manual separation and reconnection operations, minimizing opportunities for human error while maintaining operational flexibility.
Solution Approach 2:
The system is designed to maintain its own integrity without requiring manual intervention for critical connections. The mechanical and fluidic connection between collection and test blood-bags remains intact throughout the process, allowing the system to serve itself and reducing reliance on operator accuracy.
3Adaptability or versatility
If test kits are housed separately from the blood collection system, then testing can be performed independently, but the complexity of managing multiple separate components increases
Solution Approach 1:
The patent nests the test kit inside the test blood-bag, which itself is connected to the collection blood-bag. This nested arrangement integrates multiple functions (collection, testing, and containment) into a hierarchical structure, reducing the number of separate components to manage while preserving independent testing capability.
Solution Approach 2:
The patent merges the test kit with the test blood-bag into a single integrated unit. This combination eliminates the need to manage separate test kit and blood bag components, reducing overall system complexity while maintaining the ability to perform independent blood grouping and bacterial testing.

AI summary
Biomedical container (1) to collect and test blood or a blood component, comprising a collection chamber (5) for blood or a blood component; a test chamber (8) for blood or a blood component; and a test kit (4) in the test chamber (8) to test the blood or the blood component contained therein. The collection chamber (5) and the test chamber (8) are intended to be connected so as to be unequivocally mutually associated and to be supplied with the same blood or blood component.
