Device and method for determining the amount of uremia toxins removed during hemodialysis treatment

摘要

Controlling a partial dialyzate collection device in a hemodialysis machine which comprises outlet and sample-collecting val that are alternately opened and closed, comprising actuating the valves at predetermined sample-collecting time intervals, is ne The opening time of the sample-collecting valve is fixed. Independent claims are also included for the following: (1) controlling a partial dialyzate collection device in a hemodialysis machine which comprises a spent dialyzate flow mete and outlet and sample-collecting valves that are alternately opened and closed, comprising actuating the valves at fixed time interv the opening time of the sample-collecting valve is determined by the amount of dialyzate measured during the outlet valve openin time; and (2) controlling a partial dialyzate collection device in a hemodialysis machine which comprises a spent dialyzate flow mete and outlet and sample-collecting valves that are alternately opened and closed, comprising actuating the valves as soon as a predetermined volume of spent dialysis fluid has been attained.
