PROBLEM TO BE SOLVED: To provide an artificial dialyzer having an oxygen dissolution apparatus capable of efficiently and inexpensively producing a dialysate with a high oxygen dissolution purity and a high oxygen concentration and supplying the dialysate to a dialyzer or a dialysate producing and supplying apparatus as a requesting source.SOLUTION: In an artificial dialyzer S is provided an oxygen dissolution apparatus 300 having a deaeration dissolution tank 310, an oxygen supply apparatus 340, and a pressurization dissolution tank 330. The deaeration dissolution tank 310 has an oxygen purge pipe and an introduction pipe through which a dialysate is introduced from a dialyzer 100, and is communicate-connected to the pressurization dissolution tank 330. The oxygen supply apparatus 340 is oxygen suppliably connected to a communication conduit for introducing the dialysate from the deaeration dissolution tank 310 to the pressurization dissolution tank 330. The pressurization dissolution tank 330 has an oxygen supply pipe and a boosting pump for boosting the pressure of the dialysate in the tank, and is communication-connected, for supply of oxygen dissolved dialysate made in an oxygen dissolution tank, to the dialyzer 100 or a dialysate producing and supplying apparatus 200.COPYRIGHT: (C)2014,JPO&INPIT【課題】酸素溶解純度と濃度の高い透析液を効率よく安価に製造して要求もとの透析装置又は透析液製造供給装置に安定供給できる酸素溶解装置を有する人工透析装置を提供する。【解決手段】人工透析装置Sにおいて、脱気溶解タンク310と酸素供給装置340と加圧溶解タンク330とを有する酸素溶解装置300を設け、脱気溶解タンク310は、酸素パージ管と透析装置100から透析液を導入する導入管とを有すると共に加圧溶解タンク330に連通接続され、酸素供給装置340は、脱気溶解タンク310から加圧溶解タンク330に透析液を導入する連通接続用の導管に酸素を供給可能に接続され、加圧溶解タンク330は、酸素供給管とタンク内の透析液の圧力を高める昇圧ポンプとを有すると共に透析装置100又は透析液製造供給装置200に酸素溶解させたタンク内で酸素溶解した透析液を供給可能に連通接続される。【選択図】図1
