Dialysis Systems TRIZ Cases
- Urease Introducer for Sorbent Dialysis Cartridge Replenishment
An adjustable urease introducer allows precise enzyme addition to sorbent cartridges, reducing waste from variable patient loads.
- Asymmetric Diverter Column for Membrane Oxygenator Flow
An asymmetric diverter column in a membrane oxygenator directs blood flow to reduce thrombosis risk on the opposite side of the outlet.
- Blood Purification Support System Using Pre-Treatment Data Estimation
A blood purification support system estimates pre-treatment patient states using stored multi-day data to determine necessary condition changes.
- Dialysis Monitor Mounted on Swivel Front Door
A dialysis monitor mounts to a swiveling front door for ergonomic viewing.
- Variable Dialysate Flow Rate Control in Portable Hemodialysis
A portable hemodialysis system adjusts dialysate flow rates to optimize urea removal efficiency.
- Hemodialysis Wall Box Isolating Clean and Waste Fluid Zones
A hemodialysis wall box separates clean and waste fluid zones using snap-in components and anti-microbial impregnation.
- Dialysate Concentration Monitoring for Hemodialysis Effectiveness
Periodic sampling of spent dialysate enables reliable treatment assessment without frequent composition perturbations that increase noise sensitivity.
- Hemodialysis Fluid Container with Filtered Bicarbonate Dissolution
A dual-chamber container dissolves bicarbonate powder in minimal water while a filter retains undissolved particles for homogeneous solution delivery.
- TPU Heat Exchanger Tube for Oxygenator
Thermoplastic polyurethane tube with Shore hardness above 60 D resolves wall thickness control trade-offs to ensure reliable heat transfer in oxygenators.
- Dry Heating Viral Inactivation via Glass Transition Temperature Control
A method for viral inactivation by heating dried biological products to temperatures at or above their glass transition temperature.
- Single Pump Dialysate Mixing via Sequential Concentrate Addition
A single metering pump conveys specified concentrate volumes into balancing chambers across successive working cycles to produce dialysate.
- Synchronized Dual Channel Pump for CSF Membrane Dialysis
Segmenting withdrawal and return flows into a single pump reduces inflammatory mediators in cerebrospinal fluid without increasing device complexity.
