• a storage body defining a storage chamber having a second proximal end and a second distal end, the storage chamber defining an opening at one of the second proximal end and the second distal end, the storage chamber being elongated to have a second longitudinal axis distinct from the first longitudinal axis;
• a flow check valve supported on the syringe body, the flow check valve being positioned to resist backflow of liquid into the storage chamber via the second flow passage;
• a plunger positioned within the barrel body for longitudinal sliding movement therein, the plunger and extending beyond the first proximal end of the barrel body, the plunger comprising:
• a plunger rod having a third proximal end and a third distal end;
• and
• a plunger tip supported on the third distal end of the plunger rod, the plunger tip being configured to abut and seal with an internal sidewall of the barrel body;
• and
• a cap disposed within the opening at a respective one of the second proximal end and the second distal end of the storage body to seal the storage chamber;
• wherein a common wall of the syringe body extends from the first and second proximal ends to the first and second distal ends to separate and at least partially define both the dispensing chamber and the storage chamber, and wherein a second flow passage is defined by the syringe body to provide fluid communication between the storage chamber and the dispensing chamber;
• wherein the cap comprises an entry port configured to open to admit passage of a frangible ampoule into the storage chamber through the entry port, and to close to seal the storage chamber when an ampoule is not positioned within the entry port;
• and
• wherein the entry port is constructed of an elastomeric material and configured as a duckbill valve.
