1. A hemodialysis apparatus comprising:
- a dialyzing device configured to dialyze and ultrafiltrate blood of a patient circulating extracorporeally to perform hemodialysis treatment;
a measuring device configured to measure a variation rate of a body weight of the patient and a variation rate of a predetermined blood benchmark during the hemodialysis treatment using the dialyzing device; and
a calculation device configured to calculate, during the hemodialysis treatment, a parameter relating the variation rate of the body weight and the variation rate of the predetermined blood benchmark to each other, and correlating to a dry weight of the patient.

Abstract
A hemodialysis apparatus includes a dialyzing device, a measuring device and a calculation device. The dialyzing device dialyzes and ultrafiltrates blood of a patient circulating extracorporeally to perform hemodialysis treatment. The measuring device measures a variation rate of a body weight of the patient and a variation rate of a predetermined blood benchmark during the hemodialysis treatment using the dialyzing device. The calculation device calculates, during the hemodialysis treatment, a parameter relating the variation rate of the body weight and the variation rate of the predetermined blood benchmark to each other, and correlating to a dry weight of the patient.
