First Claim
1. A vial filling system for a needle-less injector, the system comprising:
- an adaptor, the adaptor having a housing including a top and a side wall extending downwardly from the top;
a recess disposed in the side wall of the adaptor for receiving a vial, the vial having an inner cavity;
an inlet opening located in the top of the adaptor, wherein when the vial is inserted into the recess the inlet opening is aligned with a nozzle of the vial;
a needle extending from the top of the housing in communication with the inlet opening, wherein the needle is constructed and arranged to pierce a container of liquid formulation; and
a plunger movably disposed within the cavity of vial for drawing the liquid formulation from the container into the cavity.
