PROBLEM TO BE SOLVED: To provide a blood purification device that can be carried by a patient who needs a dialysis treatment so that regular hospital visits or restriction over a long time are not required, and, therefore, a burden on the patient is reduced.SOLUTION: A blood purification device 1 includes: a filtration part 3 for receiving blood B1 to be treated including a waste product A, and generating diluted blood B2 that does not contain a blood component BC and concentrated blood B3 that contains the blood component BC from the blood B1 to be treated respectively by ultrafiltration and a reabsorption part 4 for discharging the diluted blood B2 whose moisture is reduced by causing the concentrated blood B3 to absorb the moisture contained in the diluted blood B2 as artificial urine U, and discharging the concentrated blood B3 that has absorbed the moisture as purified blood B4.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】透析治療を必要とする患者が携帯可能であることにより、定期的な通院や長時間の拘束を要せず、患者の負担を軽減する血液浄化装置を提供する。【解決手段】血液浄化装置1は、老廃物Aを含む被処理血液B1を受け入れて、限外濾過によって被処理血液B1から血液成分BCを含まない希薄血液B2及び血液成分BCを含む濃縮血液B3をそれぞれ生成する濾過部3と、希薄血液B2が含む水分を濃縮血液B3に吸収させることにより水分が減少した希薄血液B2を人口尿Uとして排出すると共に、水分を吸収した濃縮血液B3を浄化血液B4として排出する再吸収部4と、を備える。【選択図】図1
