Abstract
New dialysate delivery machines equipped with computer was developed to allow safe operation and compact sized design based on our long experience in prior batch type designs.
Continuous diluent water heating mechanism under evacuation is used as hardware in the compact design. Dialysate preparation is performed through doubled concentration monitorings to assure safe and failsafe operation, CPU is used in control section to operate various safety monitors including self check mechanism never found in prior machines, Furthermore. color CRT is used to monitor operation, display changes of dialysate conductivity and temperature with time, and operate by interactive information system for troubleshooting.
According to our experience on the new machines. pH. HCO3-. Ca2+and Na+ concentrations as measures of bicarbonate dialysate stability were stable and similar to those found in prio rmachines.
The foregoing means that the new machines is safe and clinically effective.
