The syringe ( 10 ) for self-injecting an extemporaneous mixture comprises: a body ( 60 ) containing at least two substances ( 36, 38 ) initially separated by an intermediate piston ( 32 ), which body ( 60 ) has two relatively movable portions ( 64, 66 ) that are movable between an initial position in which the two substances ( 36, 38 ) are separate and a final position in which the two substances ( 36, 38 ) are mixed together to form an extemporaneous mixture; automatic means ( 70, 72 ) for injecting the extemporaneous mixture out from the body ( 60 ) in order to proceed with injection; and latch means ( 73 ) for preventing triggering of the automatic injection means ( 70, 72 ). The syringe includes locking means ( 154, 109 ) for locking the latch means ( 73 ) so as to prevent the automatic injection means ( 70, 72 ) being triggered until the two substances have finished being mixed together. |
