BLOOD PURIFICATION DEVICE AND INCORRECT INSTALLATION DETECTION METHOD FOR BLOOD PURIFICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To easily detect incorrect installation of a tube using a pump and a sensor provided in an existing blood purification device.;SOLUTION: A blood purification device includes: a blood collection circuit 4 connected to a blood inlet side of a plasma separator 2; a blood pump 5 disposed in the blood collection circuit 4; a plasma circuit 6 connected to a plasma outlet side of the plasma separator 2; a plasma pump 7 disposed in the plasma circuit 6; a blood returning circuit 8 connected to a hemocyte outlet side of the plasma separator 2; and a sensor 9 to detect pressure change in the blood returning circuit 8. The blood purification device further includes a control means 12 which determines that the blood collection circuit 4 is not configured by a normal tube and outputs that effect when the pressure change detected by the sensor 9 in a state in which the blood collection circuit 4 is configured by a tube to be the determination object, the blood returning circuit 8 is closed and the blood pump 5 and the plasma pump 7 are operated, is different from prescribed normal change.;COPYRIGHT: (C)2011,JPO&INPIT
