Hydrogen Dissolution Device for Peritoneal Dialysis Fluid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing hydrogen-containing peritoneal dialysate are inconvenient and prone to contamination due to the need to immerse the dialysate container in hydrogen-containing water, leading to bacterial growth on the outer surface and potential contamination during peritoneal dialysis.
Innovation Solution
An apparatus comprising a dialysate bag and a hydrogen dissolution device with an air supply module and hydrogen supply device that dissolves hydrogen in the dialysate, eliminating the need for immersion and reducing contamination risks by using a permeable supply tube and hydrogen generator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the container with dialysate is immersed in hydrogen-containing water to add hydrogen, then hydrogen molecules can permeate into the dialysate, but the container outer surface becomes contaminated with bacteria and other microorganisms
Solution Approach 1:
The patent introduces a hydrogen permeable membrane as an intermediary between the hydrogen source and the dialysate. This membrane allows hydrogen molecules to pass through while preventing bacterial contamination, thus resolving the contradiction between achieving hydrogen dissolution and preventing contamination.
Solution Approach 2:
The patent employs a hydrogen permeable membrane with specific porosity characteristics that selectively allows hydrogen molecules to pass through while blocking larger bacterial cells and other microorganisms. This porous structure enables hydrogen transfer while maintaining sterility of the dialysate.
2Reliability
If the container is taken out of hydrogen-containing water for dialysis, then dialysis can proceed, but convenience is decreased due to the need to remove and reinsert the container
Solution Approach 1:
The hydrogen permeable membrane acts as a permanent intermediary that allows the container to remain immersed in hydrogen-containing water throughout the dialysis process without risk of contamination. This eliminates the need to repeatedly remove and reinsert the container, improving both hygiene and convenience.
Solution Approach 2:
The system is designed so that hydrogen dissolution is achieved before dialysis begins and maintained throughout the process. The membrane allows continuous hydrogen permeation, ensuring the dialysate remains hydrogen-enriched without requiring repeated handling of the container.
3Quantity of substance
If hydrogen molecules are added to dialysate by immersing the container in hydrogen-containing water, then hydrogen dissolution occurs, but the process lacks control over hydrogen concentration
Solution Approach 1:
The patent utilizes the parameter of membrane permeability to control hydrogen transfer. By selecting membranes with specific permeability characteristics, the system achieves controlled hydrogen dissolution without requiring complex control mechanisms. The permeability parameter itself becomes the control variable for hydrogen concentration.
Solution Approach 2:
The hydrogen permeable membrane serves as a controlled intermediary that regulates hydrogen transfer based on its inherent permeability properties. This natural regulation through the membrane simplifies the control system while maintaining consistent hydrogen dissolution in the dialysate.
