Abstract: An artificial lung in a circulation apparatus can be monitored and be maintained in a safe condition without manual assistance. As an extracorporeal circulation mode starts, it is determined first whether or not gas exchange of the artificial lung is carried out within a normal range, based on oxygen concentration which is detected by an oxygen sensor positioned at a downstream place in the artificial lung. If the gas exchange is carried out within the normal range, an estimated value for gas supply volume of a gas blender is maintained. When oxygen concentration exceeding the normal range is detected, the gas blender is controlled so as to revise the gas supply volume downward. In addition, when oxygen concentration falls below the normal range, the gas blender is controlled so as to revise the gas supply volume upward.

Abstract: An extracorporeal blood circulation management device having an oxygenator accurately determines oxygen consumption by the target person and oxygen delivery by the oxygenator. Oxygenation-related parameter values in the blood are determined at regular intervals. An in-body passing time (a cycle time for a particular volume of blood to pass from input sensors to output sensors) is determined. Parameter values separated by the in-body passing time are selected as comparison targets to evaluate oxygenation consumption of the target person. An oxygenator unit passing time is determined. Parameter values separated by the oxygenator unit passing time are selected as comparison targets to evaluate oxygenation delivery of the oxygenation unit.

Abstract: An extracorporeal blood circulation system reduces the risk of generation of air bubbles entering the circulation circuit associated with placement of a pressure sensor that detects a patient's blood pressure at a blood removal line. Instead of directly measuring pressure at the blood removal line where suction exists, an intermediate part pressure sensor detects pressure between a centrifugal pump and an oxygenator. A controller identifies a discharge pressure specific to the centrifugal pump based on a rotation speed of the pump and a blood flow rate. The discharge pressure and the intermediate pressure values are combined to estimate the pressure at the blood removal line.

Abstract: A tube clamp for an extracorporeal circulator recognizes various abnormal situations of the tube clamp and notifies a user. The tube clamp has a lid sensor, a tube sensor, and a plunger sensor. In a case where any one of detection of the closure of a lid portion via the lid sensor, detection of the mounting of a tube via the tube sensor, and detection of the movement of a plunger via the plunger sensor is not obtained despite the fact that there is an instruction for blocking the tube, it is determined that the blocking is abnormal. In a case where the three states including the closed state, the mounting state, and the movement state are detected despite the fact that there is no instruction for blocking the tube, it is determined that the tube is erroneously blocked. Such abnormal situations are notified to a user via an alarm.

Abstract: A highly reliable circulation apparatus promptly detects an abnormal state of a status value related to blood flowing in a circulation circuit with no particular operation performed. As an extracorporeal circulation mode starts, a user operates a pump first and waits until a flow rate is stabilized. Then, when the flow rate is stabilized, a predetermined value is added to or subtracted from the stabilized flow rate so as to set two threshold values which regulate an upper end and a lower end of a permissible state range. Then, it is monitored whether or not the flow rate is within the permissible state range regulated by the threshold values, and when the flow rate deviates from the permissible state range, an alarm is issued for notification.
