Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preparing fetal support tissue products are inefficient in preserving the biological activity and structural integrity of fetal tissues, leading to suboptimal anti-inflammatory, anti-scarring, anti-angiogenic, and wound healing properties.
Innovation Solution
A method involving the lyophilization and grinding of fetal support tissues such as placental amniotic membrane, umbilical cord, chorion, and amnion-chorion to produce a fetal support tissue powder, which is then stored and packaged for therapeutic use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional preparation methods are used for fetal support tissue products, then the processing is simpler, but the biological activity and structural integrity of fetal tissues are not effectively preserved
Solution Approach 1:
The tissue is frozen before lyophilization to preserve cellular structure and prevent degradation during the drying process. This preliminary freezing step ensures that the tissue maintains its biological activity and structural integrity throughout subsequent processing steps.
Solution Approach 2:
The method employs controlled changes in temperature and pressure parameters during lyophilization to preserve tissue properties. By carefully controlling the freezing temperature, drying pressure, and heating rate, the process maintains biological activity while removing moisture.
2Stability of the object's composition
If fetal support tissue is processed without freezing and lyophilization, then the processing time is shorter, but the structural integrity and biological activity are compromised
Solution Approach 1:
Freezing the tissue before lyophilization creates a stable structure that prevents collapse during moisture removal. This preliminary step ensures structural integrity is maintained throughout the extended processing time required for proper lyophilization.
Solution Approach 2:
The method utilizes phase transition from frozen to sublimated state during lyophilization. By transitioning water from solid to vapor phase without passing through liquid phase, the tissue structure is preserved while moisture is removed, maintaining structural integrity.
3Reliability
If fetal support tissue is ground before freezing, then the grinding process is easier, but the biological activity and structural integrity are lost
Solution Approach 1:
Freezing the tissue before grinding makes the tissue brittle and easier to grind into fine powder while preserving biological activity. The frozen state allows for more effective size reduction without compromising the therapeutic properties of the tissue components.
Solution Approach 2:
Changing the temperature parameter to frozen state before grinding transforms the mechanical properties of the tissue, making it easier to process while maintaining biological integrity. The low temperature prevents enzymatic degradation and maintains structural stability during mechanical processing.
4Reliability
If fetal support tissue is stored without proper preservation, then the storage conditions are simpler, but the anti-inflammatory, anti-scarring, and wound healing properties deteriorate
Solution Approach 1:
Lyophilization transforms the tissue into a stable dry powder form that can be stored at ambient temperature while preserving therapeutic properties. The removal of water through phase transition prevents microbial growth and enzymatic degradation, maintaining anti-inflammatory, anti-scarring, and wound healing activities.
Solution Approach 2:
Freezing before lyophilization ensures that the tissue structure is preserved during the drying process, maintaining the therapeutic properties. This preliminary freezing step creates a stable matrix that protects bioactive molecules during subsequent storage.
