Title (EN) BIOLOGICAL COMPONENT COLLECTION SYSTEM AND CIRCUIT INTERNAL PRESSURE ACQUISITION METHOD
(FR) SYSTÈME DE COLLECTE DE CONSTITUANTS BIOLOGIQUES ET PROCÉDÉ D'ACQUISITION DE PRESSION INTERNE DE CIRCUIT
Abstract:
(EN) A blood component collection system (10), which is one form of a biological component collection system, is equipped with a centrifugal separation device (14) and a biological component collection device (27). The biological component collection device (27) comprises a pressed soft portion (60) pressed by a load detecting unit (88). The centrifugal separation device (14) includes a collection and returning pump (100), and a control unit (102) having an internal pressure computation unit (103) which calculates a circuit internal pressure of the biological component collection device (27) on the basis of a detection value of the load detecting unit (88). The internal pressure computation unit (103) performs a zero reset process of setting a pressure value corresponding to the detection value of the load detecting unit (88), so as to become zero at each instance of a predetermined timing at which the collection and returning pump (100) is stopped.
(FR) La présente invention concerne un système (10) de collecte de constituants sanguins, qui est une forme d'un système de collecte de constituants biologiques, qui est équipé d'un dispositif de séparation centrifuge (14) et d'un dispositif (27) de collecte de constituants biologiques. Le dispositif (27) de collecte de constituants biologiques comprend une partie molle formée à la presse (60) qui a été formée à la presse par une unité (88) de détection de charge. Le dispositif de séparation centrifuge (14) comprend une pompe de collecte et de retour (100), et une unité de commande (102) ayant une unité (103) de calcul de pression interne qui calcule une pression interne de circuit du dispositif (27) de collecte de constituants biologiques sur la base d'une valeur de détection de l'unité (88) de détection de charge. L'unité (103) de calcul de pression interne effectue un processus de réinitialisation à zéro de réglage d'une valeur de pression correspondant à la valeur de détection de l'unité (88) de détection de charge, de sorte à devenir égale à zéro à chaque instance d'un moment prédéfini au cours duquel la pompe de collecte et de retour (100) est arrêtée.
