How It Works

DialySafe’s patent-pending technology enables real-time, objective monitoring of dialysis effluent using a capacitance-based sensing approach. Our easy-to-use, clip-on hardware integrates seamlessly into existing PD workflows: simply attach it to the fill and drain lines.

Inside the device, built-in copper electrodes form a capacitor with the dialysis fluid acting as the dielectric. As infection progresses, the effluent becomes increasingly filled with biological debris including bacteria and white blood cells which alters the fluid’s dielectric properties on a molecular level. These changes produce a detectable electrical signal.

To ensure accuracy without added burden, the system uses a differential measurement approach: it compares the capacitance of the clean fill fluid to that of the used drain effluent, automatically rejecting common-mode noise and eliminating the need for manual calibration.

Key features extracted from the signal are then analyzed by our trained machine learning algorithm, which classifies infection risk as low, medium, or high all in real-time and fully remotely.

This allows patients and caregivers to detect infections hours earlier, helping to avoid hospitalizations, preserve the catheter, and stay on peritoneal dialysis longer.
