Abstract

Devices and methods are described for filling or refilling a needle-less injector. A coupling device is attached to a vessel, and mated to the dispensing end of a needle-less injector. A volume of fluid may be transferred via the coupling device, from the vessel to the injector. Air may be removed from the injector prior to the injector, vessel, and coupling device being separated from one another. In alternate embodiments, the vessel may include filling equipment capable of filling or refilling multiple needle-less injectors simultaneously, in series, or both. In other embodiments, a coupling device may be used to withdraw a fluid from a storage vial into a vessel for filling a needle-less injector. A storage vial may alternately contain a product, and a fluid may be introduced therein via a coupling device to create a mixture, which may be subsequently withdrawn into a vessel for filling a needle-less injector.
