Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients undergoing dialysis therapies often suffer from pyrophosphate deficiencies, leading to vascular calcification, which existing dialysis solutions fail to adequately address due to instability of pyrophosphate during sterilization and storage.
Innovation Solution
Development of stable dialysis solutions containing a therapeutically effective amount of pyrophosphate, heat sterilized using techniques like autoclave or steam, with specific formulations that include bicarbonate buffers to maintain pH above 6, ensuring pyrophosphate stability during sterilization and storage, and provided in single or multi-part containers for easy administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pyrophosphate is added to dialysis solutions to prevent vascular calcification, then therapeutic efficacy is improved, but pyrophosphate stability deteriorates during sterilization and storage
Solution Approach 1:
The patent introduces bicarbonate buffer as an intermediary substance that mediates between pyrophosphate and the sterilization/storage environment. The bicarbonate buffer system maintains pH above 6, which creates a protective chemical environment that prevents pyrophosphate degradation while allowing the pyrophosphate to perform its therapeutic function of preventing vascular calcification.
Solution Approach 2:
The patent changes the pH parameter of the dialysis solution by using bicarbonate buffer to maintain pH above 6. This parameter change fundamentally alters the stability characteristics of pyrophosphate, transforming it from an unstable compound that degrades during sterilization to a stable compound that remains therapeutically effective throughout storage and administration.
2Reliability
If heat sterilization is applied to dialysis solutions to ensure sterility, then reliability is improved, but pyrophosphate stability deteriorates
Solution Approach 1:
The patent applies preliminary action by establishing the bicarbonate buffer system and adjusting pH above 6 before the heat sterilization process. This preliminary chemical preparation creates a protective environment that prevents pyrophosphate degradation during the subsequent sterilization, allowing the solution to achieve both sterility and pyrophosphate stability.
Solution Approach 2:
The patent changes the pH parameter to above 6 using bicarbonate buffer before sterilization. This parameter change transforms the chemical environment from one that causes pyrophosphate degradation during heat exposure to one that protects pyrophosphate stability, enabling successful heat sterilization without compromising the therapeutic agent.
3Reliability
If pyrophosphate is included in dialysis solutions to address vascular calcification, then therapeutic benefit is improved, but storage stability deteriorates
Solution Approach 1:
The patent changes the pH parameter to above 6 and maintains it throughout storage using bicarbonate buffer. This parameter change extends the duration of action by preventing pyrophosphate degradation over time, allowing the solution to remain stable during extended storage periods while maintaining therapeutic efficacy for preventing vascular calcification.
