Abstract:
A dialyzing apparatus comprising:a dialyzer which removes water from blood of a patient at a water-remove rate; an arteriosclerosis-related-information obtaining device which obtains arteriosclerosis-related information that is related to a degree of arteriosclerosis of the patient; a target-water-remove-rate determining means which determines a target water-remove-rate range based on the arteriosclerosis-related information of the patient and a standard body weight and an actual body weight of the patient; and a water-remove-rate display device which displays the determined target water-remove rate range; wherein the arteriosclerosis-related-information obtaining device comprises a pulse-wave-propagation-velocity measuring device which measures, as the arteriosclerosis-related-information, a pulse-wave propagation velocity at which a pulse wave propagates through an artery of the patient, wherein the target-water-remove-rate determining means determines, in a two-dimensional coordinate system which is defined by a first axis indicative of pulse-wave propagation velocity and a second axis indicative of water-remove rate, the target water-remove-rate range based on the measured pulse-wave propagation velocity according to a pre-determined relationship between pulse-wave propagation and water-remove-rate range, and wherein the water-remove rate of the dialzyer is set by an operator to a desired value in view of the target water-remove-rate range displayed by the water-remove-rate display device.
