Assembly for actuating a syringe
First Claim
1. An assembly for actuating a syringe, the syringe comprising a containment cylinder provided with at least one gripping element outwardly projecting from said containment cylinder, and a piston slidably engaged in the containment cylinder and provided with an end head, said assembly comprising:
- a first gripping device for gripping the containment cylinder, the first gripping device comprising two jaws configured for gripping the gripping element of the containment cylinder, the jaws of said first gripping device being mobile with respect to one another between a respective gripping position and a respective release position;
a second gripping device for gripping the piston, the second gripping device comprising two jaws configured for gripping the end head of the piston, the jaws of said second gripping device being mobile with respect to one another between a respective gripping position and a respective release position;
an actuation device for displacing the first and second gripping devices with respect to one another in a direction substantially parallel to a longitudinal axis of the syringe;
actuator means configured for displacing the jaws of the first and second gripping devices between the respective gripping and release positions;
a first sensor configured for measurement of the displacement of the jaws of the first gripping device at least in the respective gripping position; and
a second sensor configured for measurement of the displacement of the jaws of the second gripping device at least in the respective gripping position.
