Computational Modelling of Hollow Fibre Haemodialysers
This analysis reveals that computational modelling of hollow fibre haemodialysers, while powerful, often relies on oversimplified assumptions leading to accuracy limitations. Despite advancements, current models struggle with complex geometries, multiphysics transport, and real-world clinical variables like blood clotting and non-uniform flow. Our findings indicate a critical need for more robust, multi-scale models that integrate detailed flow dynamics, membrane characteristics, and solute interaction chemistry to accurately predict performance and support the development of next-generation artificial kidneys. Key areas for improvement include better representation of membrane tortuosity, non-Newtonian blood properties, and dynamic solute-membrane interactions.
Our AI-driven analysis quantifies the potential impact of advanced computational modeling on your enterprise, streamlining R&D and accelerating innovation.

Membrane Permeability
Understanding membrane permeability (Kp, Dm) is fundamental. Current models often simplify complex pore structures and asymmetric layers, leading to inaccuracies in predicting middle-sized solute clearance. More advanced models need to account for pore size distribution, tortuosity, and dynamic changes due to protein adsorption.
Flow Dynamics
Non-uniform blood and dialysate flow, especially in headers and around fiber bundles, significantly impacts dialyser efficiency. Existing models struggle to capture these complex 3D flow fields and wall shear stresses accurately, which are critical for predicting blood damage and local clearance variations.
Solute Transport
Transport of uraemic toxins involves diffusion and convection. Modelling needs to improve in representing protein-bound toxins (PBUTs) and their binding kinetics, as well as electrolyte exchange, which are often overlooked or simplified in current computational approaches.

Case Study: Advancing Bioartificial Kidneys
Computational models are crucial for designing implantable and bioartificial kidneys. One study developed a multi-layered membrane model for a bioartificial kidney, accurately predicting the transport of protein-bound uraemic toxins (PBUTs) and incorporating Michaelis-Menten kinetics for toxin-cell interactions. This highlights the power of detailed modelling in addressing complex physiological challenges for next-generation devices. Advanced CFD simulations allowed for optimization of membrane structure and flow paths, leading to a 15% predicted increase in PBUT clearance compared to conventional designs.
