Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processing methods for fetal support tissue products do not effectively preserve the potency and stability of bioactive components, leading to variability and impairment of therapeutic activities, and there is a risk of communicable diseases from pooling tissues from multiple donors.
Innovation Solution
The method involves pooling fetal support tissues from multiple donors, followed by lyophilization to reduce degradation and enhance the stability and concentration of bioactive components such as the HC-HA/PTX3 complex, cytokines, and growth factors, while ensuring compliance with regulatory standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fetal support tissue is processed using conventional methods, then processing is simpler, but the potency and stability of bioactive components deteriorate
Solution Approach 1:
The patent applies preliminary action by performing lyophilization (freeze-drying) on fetal support tissue before further processing or storage. This pre-treatment stabilizes bioactive components by removing water in a controlled manner, preventing degradation that would occur with conventional processing methods. The lyophilization step is performed upfront to preserve the integrity of cytokines, growth factors, and the HC-HA/PTX3 complex before subsequent pooling or formulation steps.
2Stability of the object's composition
If tissue is pooled from multiple donors, then uniformity and consistency improve, but the risk of communicable diseases increases
Solution Approach 1:
The patent applies the extraction principle by removing potentially harmful elements through rigorous screening and testing protocols before pooling tissues from multiple donors. Individual donor tissues are tested for communicable diseases and other contaminants, and only approved samples are pooled. This selective extraction of safe tissues while eliminating harmful ones allows the patent to achieve uniformity and consistency across the final product without introducing disease risks.
3Reliability
If lyophilization is applied to fetal support tissue, then stability and concentration of bioactive components increase, but processing time and energy consumption increase
Solution Approach 1:
The patent applies parameter changes by optimizing the lyophilization process conditions to achieve effective stabilization and concentration of bioactive components within reasonable timeframes. Specific parameters such as freezing temperature, primary drying temperature and pressure, and secondary drying conditions are carefully controlled and adjusted. This optimization allows the patent to obtain the stability and concentration benefits of lyophilization while minimizing excessive processing time and energy consumption through scientifically determined parameter settings.
