Dialysis Solution Extraction Ports with Segmented Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for peritoneal dialysis do not adequately ensure the sterility of extraction ports when dialysis solution is extracted multiple times from the same container, posing a risk of contamination.
Innovation Solution
A dialysis solution apparatus with multiple extraction ports and a secure connection system that allows fresh ports to be used for each extraction, including a Luer connector, valves for drainage and venting, and a sealing mechanism to prevent double use and maintain sterility, along with a tree or star structured line system and airtight sheaths to manage port usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple extraction ports are provided in the reception container, then the ability to extract dialysis solution multiple times is improved, but the risk of contamination at extraction ports increases
Solution Approach 1:
The invention divides the extraction system into multiple independent extraction ports (first extraction port, second extraction port, etc.), each capable of independent use. This segmentation allows multiple extractions from the same container while maintaining sterility at each port through independent sealing mechanisms, resolving the contradiction between multiple extraction capability and port sterility.
Solution Approach 2:
The invention implements preliminary sealing actions at each extraction port through sealing elements (such as Luer connectors with sealing rings) that are pre-configured to maintain sterility. The sealing elements are positioned and configured in advance to prevent contamination before extraction begins, ensuring reliable sterility throughout multiple extraction cycles.
2Loss of substance
If a single large container is used for multiple treatments, then waste reduction and manufacturing simplification are improved, but the complexity of ensuring sterility during multiple extractions increases
Solution Approach 1:
The invention segments the extraction interface into multiple independent ports rather than using a single complex extraction system. This allows the container to be simple and large-volume while maintaining sterility through distributed sealing elements at each port, reducing overall system complexity while enabling multiple treatments.
Solution Approach 2:
The invention employs disposable sealing elements and single-use extraction components (such as disposable Luer connectors and sealing rings) that are discarded after each extraction. This approach maintains sterility without requiring complex reusable sterilization systems, simplifying the overall device while enabling multiple treatments from the same container.
3Reliability
If extraction ports are designed for single use, then sterility is maintained, but the ability to reuse the same container for multiple treatments is reduced
Solution Approach 1:
The invention provides multiple extraction ports that can be selectively used and sealed independently. After each extraction, the used port is sealed with a disposable sealing element, allowing the same container to be reused for subsequent treatments through different ports, thus maintaining both sterility and reusability.
Solution Approach 2:
The invention implements a system where disposable sealing elements are discarded after each extraction to maintain sterility, while the container itself is recovered and reused for subsequent treatments. The sealing elements are sacrificed to protect the reusable container, enabling multiple treatments without compromising sterility.
