Abstract:
A dialyzing system comprising:a dialyzer having a dialysate outflow line and a dialysate inflow line; an ultrafiltration unit connected to the dialyzer by the dialysate outflow line and the dialysate inflow line for regulating a rate of an ultrafiltration process by regulating an outflow rate of a dialysate from the dialyzer so as to become greater than an inflow rate of the dialysate to the dialyzer; pressure-detecting means arranged in one of the dialysate flow lines to detect a pressure of the dialysate; and control means for calculating the pressure of a blood flow line connected to the dialyzer based on the pressure of the dialysate detected by the pressure-detecting means and for calculating a pressure gradient in the blood flow line based on a blood flow rate and a flow resistance of the blood flow line, said control means being adapted to determine the pressure of a blood flow line based on the pressure of the dialysate detected by the pressure-detecting means at a time of a temporary stop of the ultrafiltration process caused by temporarily stopping an operation of the ultrafiltration unit, wherein the control means monitors and displays the pressure of the blood flow line as a pressure of a specified site of the blood flow line.
