PCT No. PCT/SE95/00166 Sec. 371 Date Aug. 16, 1996 Sec. 102(e) Date Aug. 16, 1996 PCT Filed Feb. 17, 1995 PCT Pub. No. WO95/22743 PCT Pub. Date Aug. 24, 1995Apparatus for monitoring flow of a dialysis fluid through a dialyzer is disclosed including a computer for calculating the flow rate of the dialysis fluid into and out of the dialyzer based on the formula P-PO=k*Qn in which P is the pressure in the dialysis fluid between a throttle and a pump either upstream or downstream of the dialyzer, PO is the pressure in the dialysis fluid on the opposite side of the throttles from the pump, k is a characteristic coefficient for the throttle, Q is the flow of the dialysis fluid through the throttle, and N is a characteristic exponent for the throttle, and the apparatus includes microprocessor for calculating the values of k and PO prior to use and for calculating the value of PO during use of the dialyzer. Methods for carrying out such monitoring are also disclosed. |
