PROBLEM TO BE SOLVED: To replenish a dialysis patient with an appropriate amount of sugar while reducing a burden on the dialysis patient.SOLUTION: A dialysis system 1 includes: an input unit 41 capable of accepting input of a target blood glucose level which is a blood glucose level determined as a target value according to a condition of a dialysis patient, a dialysate sugar concentration which is the concentration of sugar contained in a dialysate flowing into a dialyzer, and a blood flow rate which is a liquid volume of blood flowing in the dialyzer per unit time a replenishment amount prediction unit 50 for predicting the amount of sugar solution to be replenished to the blood flowing through a blood circuit on the basis of the target blood glucose level, the dialysate sugar concentration, and the blood flow rate and a pump control unit 60 for controlling pumps 27 and 28 for feeding the sugar solution to the blood circuit so as to replenish with the sugar solution in the amount of sugar solution to be replenished.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】 本発明は、透析患者の負担を低減させながらも適量の糖を補充することを目的とする。【解決手段】 本発明の透析システム1は、目標値として透析患者の状態に応じて定められる血糖値である目標血糖値と、透析器に流入される透析液に含まれる糖の濃度である透析液糖濃度と、透析器内を単位時間あたりに流れる血液の液量である血液流量とを入力可能な入力部41と、目標血糖値、透析液糖濃度及び血液流量に基づいて、血液回路を流れる血液に補充すべき糖溶液量を予測する補充量予測部50と、補充すべき糖溶液量の糖溶液が補充されるように、糖溶液を血液回路に送り込むポンプ27,28を制御するポンプ制御部60とを含む。【選択図】 図3
