Abstract
This research is aimed to study the mechanical and electrical faults in dialysis machines, depending on four types of dialysis machines (Fresenius - B. Braun - Gambro – NIPRO). The objectives of this research are to determine the causes of these faults, their best solutions and how to prevent them in future. To verify these faults visual inspection and maintenance reports were taken into account in 80 dialysis machines in 11 dialysis centres in Khartoum state, Sudan. It was found out that these faults were due to five causes. These causes were machine pumps, power supply, conductivity, transducers, sensors and pressure failures. The mean of all faults is 21.80 and standard deviation is 3.96. The maximum mean of causes was found in power supply failure and minimum mean was found in pressure causes. The maximum standard deviation of causes was found in power failures and minimum was found in transducers and sensors failures, so the impact of the values was found homogeneous in transducers and sensors failures.
