Dialysis Systems TRIZ Cases
- Conductivity Cartridge Damping for Accurate Home Fluid Preparation
A rigid cartridge with a damper chamber and dual-frequency conductivity channels maintains accurate home medicament fluid preparation under pressure fluctuations.
- Dialysate Flow Switching for Efficient Blood Return in Dialysis
Switching between rehydration and back filtration improves blood return when flow routes occlude, while reducing dialysate use.
- Dialysis Tube Insert With Deflected Flow for Dead-Volume-Free Sampling
A deflection element and Luer-activated valve route main-line fluid into a sampling branch, cutting dead volume, rinsing steps, and fluid waste.
- Blood Purification Unit Layout for Accessible Dialysate Maintenance
A detachable second unit opens a maintenance space for filters and related parts, improving access without sacrificing mobility or compactness.
- Chlorine Sensing in Purified Water for Accurate Hemodialysis Monitoring
Automatic electrochemical chlorine sensing in purified water cuts false positives and supports safe, reliable hemodialysis water preparation.
- Dialysis Vascular Monitoring Using Venous End Pressure Changes
Venous end pressure tracking during dialysis flags stenosis, occlusion, or sclerosis in real time without extra examination equipment.
- Dialysate Degassing Vessel With CO2 Feedback Control
CO2 sensing and vacuum control improve dialysate degassing, helping maintain pH balance and prevent gas bubbles during dialysis.
- Blood Return Circuit Pressurization to Prevent Negative Pressure
Air pressurizes the dialysate circuit to drive blood return and avoid negative pressure in the blood circuit during power loss.
