Abstract:
1. A dialyzing apparatus comprising: a dialyzer which removes water from blood of a patient at a water-remove rate during a dialysis operation; a blood-pressure-change-related-information obtaining device which obtains a plurality of sorts of blood-pressure- change-related information each of which is related to a change of a blood pressure of the patient during the dialysis operation; and a water-remove-rate control device which comprises (a) a weighted-value determining means for determining, for each of the plurality of sorts of blood-pressure-change-related information, a weighted value corresponding to a change of said each sort of blood-pressure-change-related information; (b) a water-remove-rate-control-amount determining means for determining a water-remove-rate control amount based on a sum of the respective weighted values determined for the plurality of sorts of blood-pressure-change-related information; and (c) a control means for controlling the water-remove rate of the dialyzer, according to the water-remove-rate control amount determined by the water-remove-rate-control-amount determining means.
