Various dialysate delivery machines, especially delivery systems for a single patient, have been widely used for the past several years with recent developments in the technology of hemopurification. The technical problems in our use of these dialysate delivery systems were analyzed. In considering how to cope with these situations, it seems necessary to have advanced safety systems, which utilize the test-points on the printed circuit boards, and to continue to monitor the variances in electric current and voltage. The machines should also carry alarm systems in case the variances in the current and/or voltage are out of range. By utilizing those safety systems, some of the problems with the machinery can be solved before and during treatment. The current single patient dialysate delivery machines have control systems for ultrafiltration and digital indicators for the various monitors, which are very helpful for the treatment. Although usually no problems were found in the accuracy of the ultrafiltrate volume, differences between the actual and counted volume were rarely noticed. This indicates that it might be necessary for the monitor systems to check these differences inside the machine. It could also be required to use the analogue indicators for the various different purposes, rather than digital indicators, in terms of monitoring the reliability of the electricity and in maintaining the machine.
