<p>A device (1) for mixing substances to obtain an injectable medical product, the device (1) comprising a cartridge (50), a front piston (5), a front chamber (17) containing a liquid or a powder, a rear piston (6), a rear chamber (18) containing a liquid, a piston rod (7), and a bypass channel (19). The piston rod (7) is adapted to advance the rear piston (6) to collapse the rear chamber (18), whereby the liquid in the rear chamber (18) is forced to move to the front chamber (17) via the bypass channel (19). The piston rod (7) has a projection (10) which is adapted to mate with a recess (12) in the front piston (5) to provide an interlocking between the two components.</p> |
