STOPPERING METHOD TO MAINTAIN STERILITY

摘要

A syringe assembly is provided which includes a hollow barrel that has an interior wall. The interior wall defines a chamber that retains medication. The hollow barrel also includes a distal end and a proximal end. The distal end of the hollow barrel has a passageway that is in contact with the chamber. The proximal end of the hollow barrel has an aperture. The syringe assembly also includes a primary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The primary plunger tip has a receptor to engage an engager of an elongated tip removal rod. The syringe assembly also includes a secondary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The secondary plunger tip also has a receptor to engage an engager of a tip removal rod. The secondary plunger tip is disposed between the primary plunger tip and the proximal end of the hollow barrel. The syringe assembly also includes a tip removal rod, which facilitates operation of the secondary plunger tip, engaged to the secondary plunger tip. The present invention also provides a process for providing a lyophilized medication (i.e., lyophilized) in a syringe assembly and also provides a process for reconstituting a medication in a syringe assembly.
