ABSTRACT:
A multiple barrel hypodermic syringe is provided for mixing materials contained in the barrels prior to use. A typical two barrel syringe comprises a lower barrel for containing a sterile material such as a lyophilizable product, and an upper barrel containing a liquid diluent. The two barrels can be completely disengaged for separate replacement, alteration or reconstitution, etc., of their contents, if necessary.
One or more slot vents are provided along either barrel to enable release of air, gas, moisture, etc., within the lower barrel when they are partially engaged. Upon further engagement in a sterile environment, the slot vents will be totally occluded by the mating surfaces of the two barrels; this enables the syringe to be sealed and the contents stored for future use.
The hypodermic syringe of this invention also enables a lyophilization process to be carried out in situ followed by storage.
