The valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal 208 is over-molded onto a tip of the insert and an end of the piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and a barrel chamber 102. |
