First Claim
1. A syringe comprising a fluid container port for a fluid container containing fluid to be discharged, a syringe barrel with a plunger moving therein, and a discharge outlet, through which fluid supplied by actuation of the plunger in the fluid container port is dischargeable, wherein said syringe barrel is connected with the fluid container port and the discharge outlet via a fluid channel system, a valve mechanism is provided in the fluid channel system, allowing the syringe barrel to be filled with fluid supplied at the fluid container port and to then discharge said fluid through the discharge outlet, and the valve mechanism comprises a valve member which is movable between first and second positions, said valve member, in said first position, allowing fluid flow from the fluid container port to the syringe barrel and simultaneously blocking fluid flow from or to the discharge outlet and, in said second position, allowing fluid flow from the syringe barrel to the discharge outlet while simultaneously blocking fluid flow from or to the fluid container port.
