A multi-port syringe with a fluid chamber in communication with an inlet valve assembly and an outlet valve assembly disposed intermediate the fluid chamber and the inlet valve assembly, the inlet valve assembly has an inlet valve member operable in an open position and a closed position, the inlet valve member being biased in a closed position by a resilient member. The outlet valve assembly has an outlet valve member operable between a closed position and an open position, and the outlet valve member is maintained in a closed position by a sealing member, and includes anchoring member engaging the outlet valve assembly. With the outlet valve member in the closed position, the inlet valve member is forced open by compressing the resilient member, thus allowing fluid into the chamber, and with the fluid chamber primed and the inlet valve member in a closed position, the outlet valve member is forced open by disengaging the anchoring member and defeating the sealing member to allow fluid discharge from the chamber. |
