SYRINGES

摘要

A two-part syringe comprises two chambers ( 2,4 ) each chamber having an associated plunger ( 6,8 ) operable to eject fluid therefrom. The plungers ( 6,8 ) are interlinked so as selectively to prevent movement of one of said ( 6,8 ) plungers in its respective chamber ( 2,4 ) dependent upon the position of the other plunger ( 8,6 ). Such an arrangement allows lyophilised drugs to be automatically reconstituted within the syringe prior to injection into a patient.
