Abstract

An Anti-Reuse Syringe (Mode C) comprising: a hollow body (10) having a protruding conduit (14 to 16) at one end, a plunger (20) associated with the body (10) for reciprocal movement therein, a needle (37) mounted within a carrier (30), wherein the carrier (30) is mounted externally onto the wall of the protruding conduit (14 to 16) of the body (10), the plunger (20) comprising a piston (201) connected to an end of a shaft (23), the shaft (23) being manually operable to move the piston (201) towards the carrier (30) to expel liquid from the body (10) through the needle (37) wherein the piston (201) and the protruding conduit (14 to 16) include an interlocking means (141 and 202) for locking the plunger (20) with the protruding conduit (14 to 16) upon fully depressing the plunger (20) thereby trapping the plunger (20) firmly inside the body (10) wherein the shaft (23) of the plunger (20) includes a fragile portion adjacent the piston (201) to allow the shaft (23) to break upon a reuser trying to take out the plunger (20) from the protruding conduit (14 to 16) inside the body (10).
