Patent ID: 8741147

Claim:
A control method for a blood treatment equipment, said equipment comprising at least a treatment unit including a semipermeable membrane separating the treatment unit in a first compartment for the circulation of blood and in a second compartment for the circulation a of a treatment liquid and a pump coupled to a passage for the treatment liquid, the method comprising the steps: Receiving one or more entries of measured information measured during the course of a treatment procedure, Calculating from said measured information an instantaneous clearance K Ti , or dialysance value D Ti measured at treatment time T i , an effective total dialysis dosage KT Ti , value which has been delivered at the elapsed treatment time T Ti , Comparing said calculated effective total dialysis dosage KT Ti , value to at least a prescribed reference value for a total dialysis dosage value KT P to be achieved at the end of the treatment, Determining, during treatment, at least one among an estimated remaining treatment procedure time T tr and an estimated total treatment time T tot required for achieving said prescribed total dialysis dosage value KT P , Generating an output control signal responsive to said comparison, calculating a desired fluid removal rate UF from said second compartment based on said output control signal, and Automatically controlling the pump to pump the treatment liquid from the second compartment at the desired fluid removal rate UF.
