Concentrate Container Segmentation for Dialysis Fluid Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dialysis systems for patients with chronic renal failure lack a practical and location-independent solution for preparing dialysis solutions, as they require large reservoirs of dialysate that are cumbersome and require disinfection, and previous solutions have limitations in efficient preparation and storage of concentrates.
Innovation Solution
A concentrate container system with multiple compartments allows for physical separation and efficient dissolution of dry concentrates, enabling in-situ preparation of dialysis solution using a fluid container system connected via transfer lines, promoting efficient waste disposal and reducing degradation, with a modular design for location-independent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large reservoir of dialysis solution is provided in a separate device, then the dialysis machine can be used location-independently, but the system becomes cumbersome and requires time-consuming disinfection
Solution Approach 1:
The concentrate is divided into multiple compartments within a single container, allowing separate storage of different concentrate components. This segmentation enables location-independent dialysis by providing all necessary concentrates in one portable unit, eliminating the need for separate reservoirs and complex disinfection procedures.
2Device complexity
If concentrates are stored in a single container, then the device is simpler, but different concentrates may mix and degrade before use
Solution Approach 1:
The concentrate container is divided into multiple compartments that physically separate different concentrate components. This prevents premature mixing and degradation while maintaining a simple single-container structure. The compartments remain separated during transport and only mix during the dialysis treatment when diluent is added.
Solution Approach 2:
Multiple compartments are nested within a single outer container structure. This nested design allows different concentrates to be stored separately in individual compartments while being housed within one portable unit, combining simplicity of structure with reliability of separation.
3Device complexity
If dialysis solution is prepared in advance and transferred to storage bags, then the system is simpler, but the preparation process is time-consuming and requires additional equipment
Solution Approach 1:
The concentrate components are pre-packaged in separate compartments within the container during manufacturing. This preliminary action eliminates the need for time-consuming preparation steps at the dialysis site, as the concentrates are already separated and ready for immediate use when diluent is added during treatment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
