Claim 5:
6. A method for mixing a pharmaceutic composition, comprising:
providing a syringe mixing system, the system comprising a valve assembly with 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;
wherein the displaceable member comprises at least one resilient projection and the guide member comprises at least one recess for receiving the at least one resilient projection; and
wherein the at least one resilient projection is operable to be displaced upon movement of the displaceable member from a first position and wherein the at least one resilient projection prevents or inhibits the displaceable member from being returned to the first position when it is provided in the at least one recess of the guide member;
coupling a first syringe and a second syringe to the valve assembly, wherein the first syringe and the second syringe each comprise a syringe barrel with a hollow body defining an internal chamber, wherein the syringe barrel has a proximal end and a distal dispensing end with an outlet, and a plunger slidably disposed within the hollow body for applying pressure to a syringe content housed within the internal chamber;
displacing the displaceable member relative to the guide member in a direction substantially perpendicular to a longitudinal axis of at least one of the first syringe and the second; and
cyclically mixing contents between the first syringe and the second syringe to prepare the contents for delivery to a patient.
