Integrated Flush IV Bag with Peelable Seam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IV drug administration methods result in significant drug loss due to residual volumes in containers and giving sets, posing challenges in ensuring accurate delivery and increasing the risk of contamination.
Innovation Solution
A flexible IV container with two chambers separated by a peelable seam, where one chamber is for the medication and the other for flushing, allowing for a closed system administration that ensures complete drug delivery without the need for external flushing systems, reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard IV containers and giving sets are used for drug administration, then the administration process is simple, but significant drug loss occurs due to residual volumes in the container and giving set
Solution Approach 1:
The IV container is divided into multiple chambers separated by a peelable seam. The first chamber contains the medication and initial diluent, while the second chamber contains additional diluent for flushing. This segmentation allows the flushing function to be integrated into the container itself, enabling complete drug delivery without significant residual loss while maintaining operational simplicity.
2Loss of substance
If external flushing systems (second IV perfusion or flush syringe) are used to deliver remaining drug, then complete drug delivery is achieved, but the system is no longer closed increasing contamination risk
Solution Approach 1:
The flushing function is merged with the original IV container by integrating a second chamber within the same container structure. This allows the flushing process to occur within a closed system, eliminating the need for external flushing devices and thereby maintaining sterility while achieving complete drug delivery.
Solution Approach 2:
The peelable seam acts as an intermediary mechanism that maintains the closed system integrity during storage and administration, then allows controlled communication between chambers when needed. This intermediary structure enables the system to transition from a sealed state to an active flushing state without compromising sterility.
3Loss of substance
If external flushing systems are used, then drug delivery is improved, but device complexity and handling difficulty increase
Solution Approach 1:
The flushing function is combined with the medication container into a single integrated unit with two chambers. This merging eliminates the need for separate flushing devices, reducing overall system complexity while maintaining the ability to deliver complete drug doses.
4Adaptability or versatility
If multiple openings are provided for filling chambers, then filling flexibility is improved, but contamination risk and manufacturing complexity increase
Solution Approach 1:
A single opening in the container serves multiple functions: it is used for filling both the first chamber (medication) and the second chamber (flushing diluent), and for administering the contents to the patient. This multi-functional opening reduces contamination risk compared to multiple separate openings while maintaining filling flexibility.
