摘要： 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.

摘要： An extracorporeal blood circulation system monitors blood level in a reservoir which temporarily stores the blood. A memory storage unit stores blood pressure measurements from a pressure sensor monitoring a blood pressure within a tube unit conveying blood from the reservoir relative to atmosphere. A processing unit that detects a height of a top surface of the blood stored in the reservoir based on changes in the blood pressure measurements and a conservation of mechanical energy of a blood flow inside the tube unit. A notification is generated if an abnormality is detected in the height of the blood in the reservoir.

摘要： An extracorporeal circulation apparatus has a blood reservoir temporarily storing blood and a presence information acquisition unit to detect presence or absence of blood at respective wall locations in a two-dimensional array. A control unit determines the position of a blood surface on the basis of consecutive elements in the array having detected blood along at least one of a first direction parallel to the blood surface and a second direction perpendicular to the blood surface.

摘要： An extracorporeal circulation management device pumps blood in synchronization with heartbeats of a patient based on measurements of blood flow. Maximum and minimum blood flow measurement samples are compared with upper and lower threshold values to identify candidate timing for a systolic phase and diastolic phase of the heartbeat. During pulsatile pumping of the blood using the candidate timing, differences in the pulsatile flow measurements are determined. Based on the size of the difference, a final correction may be made to identification of the systolic and diastolic phases, and the corrected phase information is used to start and stop the motor unit.

摘要： An extracorporeal blood circulator includes a control unit and a speed manipulation section. A rotation display section displays a lower limit rotation setting value of a pump motor in accordance with a command of the control unit. The lower limit rotation speed setting value is a minimum rotation speed for preventing backflow of blood inside a circulation circuit A manually adjusted speed setting request from the manipulation section controls the pump speed, except that the controller enforces the lower limit speed setting unless receiving confirmation from a manipulator.
