Analysis method in dialysis and analysis device for dialysis

The invention provides an analysis method in dialysis and an analysis device for dialysis. The method comprises the following steps of: obtaining one or more input characteristics; the input features include operating parameters related to the dialysis machine and a change relationship between current data and previous data of the person to be tested. Future data is predicted by one or more prediction models in accordance with the input features. The future data comprises blood pressure information at a future time point and a prediction result of hypotension in dialysis. Consequently, hypotension in dialysis can be predicted with high accuracy.
