Dry Acid Concentrate Container for Dialysis Solution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for preparing dialysis solutions are complex, costly, and labor-intensive due to the need for liquid acid concentrates, which require cumbersome canisters and central supply systems, leading to high transportation and storage costs, as well as challenging disinfection and cleaning processes.
Innovation Solution
A dry acid concentrate is provided in a container that can be dissolved on-site to form an acid liquid concentrate, eliminating the need for heavy canisters and central supply systems by using a container connected to a dialyzer or local preparation unit, allowing for the production of a dialysis solution with specific ion concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid acid concentrate is supplied in canisters, then the concentrate can be used for manufacturing dialysis solution, but the handling becomes complex and transportation and storage costs increase due to high weight
Solution Approach 1:
The patent changes the physical state of the acid concentrate from liquid to dry form. This parameter change dramatically reduces the weight of the container while maintaining the same functional capability to provide acid concentrate for dialysis solution manufacturing. The dry concentrate is supplied in lightweight containers and reconstituted with water at the point of use.
2Ease of manufacture
If liquid acid concentrate is supplied in canisters, then the concentrate can be used for manufacturing dialysis solution, but transportation and storage costs increase
Solution Approach 1:
The patent transforms the acid concentrate from liquid to dry form, which reduces the weight of storage containers and associated infrastructure. This parameter change leads to lower transportation and storage costs while maintaining the ability to manufacture dialysis solution at the point of use.
3Productivity
If central supply unit with mixing apparatus is used, then acid liquid concentrate can be manufactured, but disinfection and cleaning become laborious, expensive and pollutive
Solution Approach 1:
The patent employs disposable containers for dry acid concentrate that are single-use. Each container is sealed and sterile until use, eliminating the need for complex disinfection and cleaning procedures associated with reusable central supply systems. After use, the container is discarded, avoiding contamination issues entirely.
4Productivity
If central supply unit with mixing apparatus is used, then acid liquid concentrate can be manufactured, but costs increase and it is only economical for larger treatment centers
Solution Approach 1:
The patent segments the acid concentrate supply into individual disposable containers, each containing dry concentrate. This segmentation eliminates the need for a centralized mixing system, allowing each treatment station to independently prepare its own acid concentrate by adding water to the dry powder in the container.
Solution Approach 2:
The patent enables self-service at each treatment station by providing dry acid concentrate in containers that can be reconstituted with water using simple equipment already present at the dialysis station. This eliminates dependence on complex central supply systems and makes the solution economical for treatment centers of any size.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the handling and storage of acid concentrates, reduces transportation costs, and facilitates efficient on-site production of dialysis solutions with precise ion concentrations, making the process more economical and easier to manage, especially for smaller treatment centers.
Implementation Method 1
the dry concentrate located in the container is designed so that, on its solution in a liquid, preferably in water, it forms an acid liquid concentrate
Data Source
AI summary
A container includes a dry concentrate designed such that the dry concentrate forms an acid liquid concentrate, or a part of an acid liquid concentrate, which is suitable for manufacturing a dialysis solution, on the dissolution of the dry concentrate in a liquid, preferably in water.
