1. A syringe-to-syringe mixing system comprising:
a first syringe comprising a hollow body, the hollow body having a proximal end and a distal dispensing end;
a second syringe comprising a hollow body, the second syringe comprising a distal dispensing end;
the first syringe and the second syringe each comprising a barrel and a plunger for applying pressure to a syringe content;
a valve assembly that is operable to receive the first syringe and the second syringe, and wherein the valve assembly comprises at least one resilient member that is biased toward a locked position;
wherein the valve assembly comprises a displaceable member comprising a user-interface and a guide member, wherein the displaceable member is slidable relative to the guide member, and wherein the user-interface is operable to receive a force from a user and transmit the force to a displaceable seal, and wherein the displaceable seal is moveable in a direction substantially perpendicular to a longitudinal axis of at least one of the first syringe and the second syringe;
a selectively rotatable member operable to receive at least one of the first syringe and the second syringe;
wherein the valve assembly comprises a first position wherein a fluid flow between the first syringe and the second syringe through the displaceable seal is fully occluded, and a second position in which fluid is allowed to flow through the displaceable seal and between the first syringe and the second syringe;
wherein the displaceable member comprises at least one projection in communication with the selectively rotatable member when the displaceable member is in the first position, and wherein the at least one projection is spaced apart from the selectively rotatable member when the displaceable member is in the second position and the selectively rotatable member is freely rotatable when the displaceable member is in the second position.
