Abstract:
1. A system for use in filling one or more reservoirs, the system comprising: a vial having an interior volume for containing a liquid; a diaphragm arranged in the vial, the diaphragm defining a pressurizable volume, the diaphragm separating the interior volume of the vial from the pressurizable volume, the diaphragm inflatable to expel liquid from the interior volume in a case where a pressure within the pressurizable volume is increased to inflate the diaphragm; and a reservoir having an interior volume; said diaphragm being inflatable to force liquid out of the interior volume of the vial and into the interior volume of the reservoir in a case where the interior volume of the vial is holding the liquid and the interior volume of the vial is connected to the interior volume of the reservoir by a needle and the pressure within the pressurizable volume is increased; wherein a flow path between the interior volume of the vial and the interior volume of the reservoir is configured to reduce air bubbles from passing in the liquid as the liquid is transferred from the interior volume of the vial to the interior volume of the reservoir.
