Abstract

Introduction: The decrease in the pressure of the dialyzed fluid is associated with the loss of power of the motors that pressurize the system in a volumetric hemodiafiltration machine. We present a way to maintain the operability of hemodiafiltration treatment.

Technical case: The monitor is an NCU-18-Nipro hemodiafiltration machine with 14426 hours of use. During the startup test, the system reported an error in the flow control of ultrafilter one due to a loss of power from pump 1 of the dialysate flow; the position of 
the head from pump P2 to pump P1 was changed. , and system pressurization calibration. The problem was temporarily resolved for three months. After this period, the error occurred again; it was decided to hyper-pressurize the system, with which the machine 
entered the entire operation for three additional months. Once the new head of the CFL1 pump has arrived, it is verified that the pump's base has also lost strength; the base change is planned. The machine is kept operational by hyper-pressurizing the system, and with hyper-pressurizing, the reducing valve at the point of entry of water from the ring; the machine operates with a maximum of 22 liters of replacement, this maneuver gave enough time to import the base of the pump.

Conclusion: The hypertension of the dialysate fluid pressurization system is a compensatory measure for the failure of pressurization pumps, which gives 3 to 6 additional months for the change of spare parts; however, this procedure causes a charge to the motor of the pumps, which determines a change of the same ones at the end of the second period.
