MODULAR HOME DIALYSIS SYSTEM

摘要

A machine for conducting dialysis of body fluids of a patient. The machine includes integral water preparation and treatment, dialysate preparation, and extracorporeal circuit modules, under computer control from a patient interface and control module. A water pretreatment module with a temperature-controlled mixing valve, an integral water filtration and conditioning unit and a pressure relief with integral water sample removal port supplies water to the machine. The dialysate preparation module includes a substantially non-compliant tank with attached batch chemical bottles and automatic chemical addition and dispersion subsystems. The machine incorporates novel automatic process control techniques to verify the status and integrity of the critical system components, ultrafiltration control, and temperature, pressure and conductivity conditions prior to dialysis.
