Haemofiltration TRIZ Cases
- Dialyzer Flow Rate Estimation via Acoustic Impedance Sensors
Acoustic impedance sensors estimate dialyzer fluid flow rates to resolve measurement precision and real-time control reliability contradictions.
- Venous-Venous Blood CO2 Removal System
Segmenting plasmatic water enables efficient CO2 removal without exposing cellular components to damaging procedures.
- Dialysis Monitor with Polarization and Anti-Reflection Coatings
A dialysis monitor integrates polarization filters and anti-reflective coatings to optimize display visibility for clinical operators.
- Flexible Manifold for Wearable Artificial Kidney
Hinged manifold plates enable dialysate regeneration in a portable wearable kidney, reducing ion depletion and improving home treatment convenience.
- Infusate Holder with Segmented Compartments for Dialysis
A segmented infusate holder aligns internal compartments with dialysis machine connectors to prevent incorrect assembly and reduce cleaning requirements.
- Analysis Cartridge Filter Unit Foil Integration
Integrating the filter material directly into the processing chamber eliminates fluid loss during transport while reducing structural complexity.
- Blood Pump Medication Delivery via Pressure Monitoring
An extracorporeal blood treatment device uses a single pump and pressure sensors to determine medication volume, eliminating separate delivery hardware.
- Peristaltic Pump Monitoring via Power and Pressure Signal Analysis
Monitoring power and pressure signals identifies tubing mispositioning and faulty guidance in extracorporeal blood treatment devices, preventing damage.
- Blood Treatment Apparatus Dynamic Transmembrane Pressure Control
A blood treatment apparatus adjusts transmembrane pressure using real-time sensor feedback to optimize convective exchange.
- Bag Hanger Assembly for Blood Therapy Load Cell Protection
A freely hanging link decouples the load cell from adjacent bag contact, preventing inaccurate weight readings during blood therapy.
- Lateral Flow Filter with Pore Gradient for Blood Filtration
Segmented filter layers prevent clogging and eliminate peripheral flows, maximizing plasma outflow volume in thin capillary cartridges.
- Blood Treatment Cassette Alignment Latching Tilt-Tolerance
Two spaced-apart alignment devices define translational displacement and angular orientation, minimizing tilting and material stress during equipping.
- Hemodialysis Fluid Replacement Blockage Detection
A hemodialysis system measures dialysate discharge time to detect fluid replacement passage blockages.
- Portable Ultrafiltration Device with Intelligent Control
An intelligent central unit manages fluid extraction in a portable ultrafiltration device, preventing over-extraction shock through automated volume monitoring.
- Microfluidic Device Pressure Control for Convective Clearance
Segmented channels with controlled pressure gradients boost convective clearance without increasing channel length or compromising hematocrit safety.
- Displaceable Holding Portion for Peristaltic Pump Tube Attachment
Rocking holding portions release interference loads on peristaltic pump tubes, resolving the trade-off between secure operation and easy manual handling.
- Targeted Apheresis for Pre-eclampsia Treatment
Targeted apheresis removes circulating sFlt-1 receptors via immobilized aptamers, sparing cellular Flt-1 to protect mother and baby.
- Plasma Collection with Remote Programming and Hematocrit Adjustment
Automated nomogram adjustments based on donor hematocrit eliminate manual calculation errors while maximizing raw plasma collection volumes.
