Patent ID: 6878273

Claim:
A dialyzing apparatus comprising: a dialyzer which removes water from blood of a patient at a pre-set water-remove rate; an autonomic-nerve-activity-related-information obtaining device which obtains autonomic-nerve-activity-related information that is related to an activity of an autonomic nerve of the patient, the autonomic-nerve-activity-related information being any one of(a) a low-frequency component of fluctuations of blood-pressure values of the patient, (b) a high-frequency component of fluctuations of pulse-period values of the patient, and (c) a pressoreceptor-reflex sensitivity defined as a ratio of one of the low-frequency component and the high-frequency component to the other of the two components; a target-water-remove-rate determining means for determining a target-water-remove rate based on autonomic-nerve-activity-related information obtained by the autonomic-nerve-activity-related-information obtaining device; and a water-remove-rate display device which displays the target water-remove rate determined by the target-water-remove-rate determining means; wherein the water-remove rate of the dialyzer is set by an operator to a desired water-remove rate in view of the target water-remove rate displayed by the water-remove-rate display device.
