環型肺補助装置。[Claim for Utility Model Registration] The patient's extracorporeally circulating blood and dialysate are brought into contact with each other through a membrane in the dialyzer, and the carbon dioxide component in the blood is transferred into the dialysate, and this dialysate is transferred into a diffusion cylinder. In a pulmonary assist device that regenerates and circulates dialysate by bringing it into airtight contact with an inert gas and dissipating and removing it as carbon dioxide gas, means for inputting gas partial pressure data of a patient's blood and dialysate, respectively; An extracorporeal circulation type lung assist device characterized by comprising means for predicting and calculating the gas partial pressure of the blood, which changes with the passage of time of extracorporeal circulation treatment, from these input values, and means for displaying the predicted calculation results. .
