Current bioreactor systems for tissue perfusion, such as those used in clinical and research environments, face limitations in maintaining the tumor microenvironment and anatomical accuracy, leading to unreliable data interpretation and lack of effective models for vesicant-induced injury studies.
Innovation Solution
A bioreactor system with an AI module that includes a media reservoir, peristaltic pump, perfusion chamber, and sensors, capable of extended tissue perfusion up to three weeks, using Dulbecco's Modified Eagle Medium with bovine serum albumin to maintain tissue architecture, and employing AI for real-time monitoring and control to ensure optimal conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current bioreactor systems are used for tissue perfusion, then basic perfusion function is provided, but the tumor microenvironment cannot be maintained and anatomical accuracy is lost
Solution Approach 1:
The bioreactor system is divided into distinct functional modules: a perfusion module for fluid delivery, a imaging module for real-time monitoring, a control module with AI algorithms, and a tissue mounting system. This segmentation allows each module to be optimized independently while maintaining the tumor microenvironment, resolving the contradiction between reliability and complexity.
Solution Approach 2:
An AI-based control system acts as an intermediary between the various bioreactor components, coordinating perfusion parameters, imaging timing, and environmental controls. This intelligent mediator ensures the tumor microenvironment is maintained without requiring complex manual coordination of all system components.
2Duration of action of moving object
If perfusion period is extended for long-term studies, then research value increases, but tissue viability and system stability deteriorate
Solution Approach 1:
The system incorporates real-time feedback through integrated imaging that continuously monitors tissue health indicators. AI algorithms analyze these images to detect early signs of tissue stress or degradation, automatically adjusting perfusion parameters to extend viable perfusion period while maintaining tissue viability throughout the experiment.
Solution Approach 2:
The bioreactor maintains continuous perfusion with optimized flow rates and media composition throughout the extended experimental period. The system provides uninterrupted nutrient delivery and waste removal, enabling long-term studies (days to weeks) while preserving tissue viability through sustained optimal conditions.
3Reliability
If AI control is implemented for real-time monitoring, then operational reliability improves, but system complexity and computational requirements increase
Solution Approach 1:
The AI control system operates autonomously, automatically analyzing imaging data, detecting tissue status changes, and adjusting perfusion parameters without human intervention. This self-service capability improves operational reliability while the modular architecture keeps overall system complexity manageable through automated intelligence.
4Adaptability or versatility
If human tissue samples are used for perfusion studies, then clinical relevance improves, but availability and ethical constraints worsen
Solution Approach 1:
The system is designed to accommodate various tissue types including human samples, animal models, and engineered tissues. By preparing the bioreactor with versatile mounting capabilities and compatible perfusion systems in advance, the platform can quickly adapt to different tissue sources, improving clinical relevance while managing sample availability constraints through proactive system preparation.
