The present invention concerns a device for injecting a liquid product contained in a bag, the device comprising a housing consisting of two half-shells articulated about an axis of rotation in order to allow the relative movement of the half-shells relative to each other between: &#x2014;an open position in order to put the bag in place and&#x2014;a closed position for injecting the liquid product contained in the bag, remarkable in that: &#x2014;one of the half-shells comprises a deformable bladder&#x2014;called the 'active bladder'&#x2014;having a volume that varies under the action of a hydraulic ram supplying said bladder with hydraulic fluid, and&#x2014;the other of the half-shells comprises a deformable damping cushion having a constant volume&#x2014;called the 'passive cushion'.

Device for injecting a liquid product comprising two half-shells rotatably mobile relative to each other

The invention concerns an device for injecting a patient with a liquid product contained in a container (), the system comprising a pressurizing unit for driving the liquid product contained in the container, the system further comprising a calculator for estimating the injection flow rate at the outlet of the container, said injection flow rate at the outlet being estimated on the basis of a law of deformation of the system under the effect of the pressure inside the container.
