Summary: | A device ( 1 ) for medical use, of the prefilled ready-to-use syringe type, comprising a tubular body ( 2 ) comprising, at its distal end ( 4 ), a tip ( 5 ) to take a needle and, at its proximal end ( 12 ), a piston ( 3 ) able to slide inside the said tubular body ( 2 ), the said piston ( 3 ) being arranged in an initial position, with respect to the tubular body ( 2 ), defining an internal working volume ( 8 ) at least partially filled with a medicinal liquid ( 9 ), the piston ( 3 ) being connected to a rod ( 11 ) for actuating the said piston, characterized in that the tubular body ( 2 ) is provided, on its internal face ( 13 ), with a means ( 14 ) of detecting the movement of the piston ( 3 ), the said means ( 14 ) being situated between the initial position of the piston and the proximal end ( 12 ) of the tubular body ( 2 ). The present invention also relates to a method for manufacturing such a device. |
