Title
(EN) BIOLOGICAL COMPONENT COLLECTION SYSTEM AND CIRCUIT INTERNAL PRESSURE ACQUISITION METHOD
(FR) SYSTÈME DE RÉCUPÉRATION DE COMPOSANTS BIOLOGIQUES ET PROCÉDÉ D’ACQUISITION DE PRESSION INTERNE DE CIRCUIT
Abstract
(EN)
A biological component collection system and a circuit internal pressure acquisition method are provided, which are capable of accurately measuring the circuit internal pressure. A centrifugal separation device (14) of a blood component collection system (10) comprises a data acquisition unit (106) that acquires initial data A before blood component collection is carried out in a cassette attached state, an estimated data calculation unit (112) that calculates estimated data B on the basis of the initial data A, a reaction force calculation unit (116) which, during blood component collection, calculates a reaction force of a first applied load measurement unit (60) on the basis of the estimated data B, and an internal pressure calculation unit (118) that calculates an internal pressure of the first applied load measurement unit (60), on the basis of the reaction force calculated by the reaction force calculation unit (116) and a load detected by a first load detecting unit (88).

La présente invention concerne un système de récupération de composants biologiques et un procédé d’acquisition de pression interne de circuit qui peuvent mesurer avec précision la pression interne de circuit. Un dispositif de séparation centrifuge (14) d’un système de récupération des composants du sang (10) comprend une unité d’acquisition de données (106) qui acquiert des données initiales A avant que la récupération des composants du sang soit effectuée dans un état attaché à une cassette, une unité de calcul de données estimées (112) qui calcule les données estimées B sur la base des données initiales A, une unité de calcul de force de réaction (116) qui, pendant la récupération des composants du sang, calcule une force de réaction d’une première unité de mesure de charge appliquée (60) sur la base des données estimées B, et une unité de calcul de pression interne (118) qui calcule une pression interne de la première unité de mesure de charge appliquée (60), sur la base de la force de réaction calculée par l’unité de calcul de force réactionnelle (116) et une charge détectée par une première unité de détection de charge (88).
