26 The principle of VCS (Viscous Control System) Dialysate mixing As shown in the below Fig., water is supplied to the right side of the viscous chamber. By upward movement of piston of the viscous pump during temporally stop of the water supply, A concentrate (for bicarbonate dialysis) of a volume corresponding to the piston stroke is aspirated in the right side. By changing the piston stroke, dialysate concentration can be changed. During the supply and aspiration, used dialysate is drained from the left side. UF control As shown in the below Fig., fresh dialysate prepared in the right side is transferred to the left side through dialyzer by operating the pump. By upward movement of piston of the viscous pump, capacity of closed circuit (shown as bold lines) is increased, generating negative pressure in dialysate compartment of the dialyzer. As the result, fluid of a volume corresponding to the piston movement is removed from blood. By changing the piston stroke, it is possible to change UF. The system is build up so that dialysate preparation and UF control cycle is alternating, which means that two sets are provided in the system. US and JAPAN PATENTS 4-4

37 Connection for acetic acid rinsing (when acid rinse option is not used) (1) Connect connector placed at rear side of the machine for disinfectant concentrate to container for acetic acid concentrate. (2) Check whether connectors of the machine for A and B concentrates are connected to respective rinse ports securely. CAUTION Connect each concentrate connector and the like securely. Otherwise, trouble such as water leak or air aspiration may be caused Connection for acetic acid rinsing (when acid rinse option is used) (1) Connect connector placed at rear side of the machine for acetic acid concentrate to container for the concentrate. (2) Check whether 3 connectors for A, B and disinfectant concentrates are connected to respective rinse ports securely. CAUTION Connect each concentrate connector and the like securely. Otherwise, trouble such as fluid leak or air aspiration may be caused Connection for automatic rinsing (1 or 2) (when acid rinse option is used) (1) Connect connector placed at rear side of the machine for disinfectant concentrate to container for the concentrate. (2) Connect connector placed at rear side of the machine for acetic acid concentrate to container for the concentrate. (3) Check whether connectors of the machine for A and B concentrates are connected to respective rinse ports securely. CAUTION Connect each concentrate connector, rinse port and the like securely. Otherwise, trouble such as water leak or air aspiration may be caused. Use disinfectant and acetic acid concentrates of specified concentrations. 6-10

38 Air purge The machine is shipped after filling fluid line with air. To install the machine, remove air in accordance with the procedures shown in message screen of display. The air is removed automatically within 7 to 10 minutes. CAUTION Before starting air purge, check whether water supply is enabled. If disabled, pump may be damaged due to unloaded operation. NOTE When the machine is turned on after long term, date and time may be initialized and E50 RAM INITIALIZE error may be occurred to initialize SETTING 1 screen. Because RAM back up battery is emptied. The check and re-input should be performed by well trained person. RAM back up battery is rechargeable. It is full charged by power on the machine about 22 hours continuously. It is emptied by turn off the machine about 7-10 days. (1) Check whether all connectors are connected to respective rinse ports correctly. (2) Check whether water can be supplied. (3) The air purge process is enabled during rinse wait mode only. Select the mode. (4) Press [F 5] SW to display maintenance mode menu. (5) Press [F 3] or [F 4] SW to select "MODE9 followed by pressing [F 1] SW. (6) After checking display of [MAINTE 9], press [F 1] SW to start the air purge process. (7) To terminate the process forcibly during its execution, press [F 1] SW. (8) Upon completion of the process, it is shown in the message screen. 6-11

39 6.5. Disinfection of the dialysate circuit Be sure to disinfect the dialysate circuit before use of the machine Disposal of used machine Procedures how to dispose materials of the machine are described below: (a) Resin such as electrical circuit board and silicone oil; rubber and electric wire should be disposed as industrial waste. If the disposal is covered by regional regulation, dispose them based on it. (b) To distinguish iron from stainless steel, use magnet because the iron is attracted by it, while the stainless steel is not so. The iron is surface finished by painting or plating to prevent rust formation Disposal of used packaging materials Dispose used packaging materials after separating to groups of wood, styrol foam, corrugated board and the like Disposal of blood lines and dialyzer Dispose used blood lines and dialyzer by suitable manners specified by hospital or medical facilities to prevent risk of infection. 6-12
