<p>Double chamber syringe comprising a first chamber (10) defined by a first cylinder (12) closed at one end by a first wall (13) wherein is provided an opening (15), and at its other end by a first sliding piston (14). Said syringe further comprises a second cylinder (17) which is coaxial and internal to the first cylinder and fixed by its first end to the first piston and closed at its second end by a second wall (18), and a rod (16) coaxial and internal to the second cylinder and fixed to the first wall by its first end, and slidingly traversing the first piston (14) and supporting at its other end a second piston (19) sliding into the second cylinder. Thus, a second chamber (11) is defined by the second cylinder, the second piston and the second wall, the volumes of both chambers varying simultaneously when the second cylinder is displaced with respect to the first cylinder. Application for medical syringes.</p> |
