Abstract[English]
The present invention is concerned with an operating assembly (1) and with a computer implemented method for a prefilled syringe (7) comprising: - a fixture (2) to accommodate the prefilled syringe (7), - a plunger rod (6) operatively coupled to the fixture (2 - a data acquisition unit (20) accommodated either by the fixture (2) or the plunger rod (6), - at least two interaction structures (11, 12), whereby one of the interaction structures is provided by the fixture (2) and the other by the plunger rod (6), wherein the interaction structures (11, 12) are mutually shaped and arranged in such a way a frictional force may act between them which occurs repeatedly during an ejection stroke wherein the acceleration and the speed of both the fixture (2) and the plunger rod (6) are modulated accordingly, wherein the data acquisition unit (20) captures a signal (27) evoked by said modulated speed and acceleration.[French]
La présente invention concerne un ensemble d’actionnement (1) et un procédé mis en œuvre par ordinateur pour une seringue pré-remplie (7) comprenant : - un dispositif de fixation (2) pour recevoir la seringue pré-remplie (7), - une tige de piston (6) couplée de manière fonctionnelle au dispositif de fixation (2), - une unité d’acquisition de données (20) logée soit par le dispositif de fixation (2) soit par la tige de piston (6), - au moins deux structures d’interaction (11, 12), l’une des structures d’interaction étant fournie par le dispositif de fixation (2) et l’autre par la tige de piston (6), les structures d’interaction (11, 12) étant mutuellement façonnées et agencées de telle sorte qu’une force de frottement peut agir entre elles, ladite force étant générée de manière répétée pendant une course d’éjection, l’accélération et la vitesse à la fois du dispositif de fixation (2) et de la tige de piston (6) étant modulées en conséquence, l’unité d’acquisition de données (20) capturant un signal (27) généré par lesdites vitesse et accélération modulées.
