The sacks are connected to the patient catheter for carrying out peritoneal dialysis. The device has pump connected to housing for creating space with no access of air, excessive pressure or rarefaction inside the housing, respectively. Valve units connect heating sack or discharge sack to patient catheter. When creating rarefaction in the housing, fresh dialysis solution is supplied into the heating sack from the delivery sack. The wasted liquid is removed from the abdominal cavity into the discharge sack. When creating excessive pressure in the housing, warm dialysis solution is supplied from the heating sack to the patient. The discharge sack is drained into juice or into accumulating sacks. The dialysis solution flow is controlled by the device by means of weighing the housing with its contents. Data required for performing treatment procedure are stored in the storage unit. EFFECT: easy in use for patient. 15 cl, 9 dwg
