Automated filling systems and methods

摘要

Various embodiments of the present invention are directed to transferring fluidic media from a vial to a reservoir. In various embodiments, fluidic media may be transferred from the vial to the reservoir by moving a housing portion to move a plunger head located in the reservoir to draw fluidic media from the vial to the reservoir. In other embodiments, fluidic media may be transferred from the vial to the reservoir while the reservoir is held by a holding unit and vibrated by a vibrator to remove air from the fluidic media. In some embodiments, fluidic media may be transferred from the vial to the reservoir by moving a handle operatively connected to a bias member for assisting with the transfer of fluidic media. In other embodiments, the transfer of fluidic media may be assisted by a bias member and a needle connecting atmosphere and the vial.

1. A system for automated pressure equalization, the system comprising:
a transfer guard, the transfer guard comprising: a first needle having a fluid path for transferring fluidic media from an interior volume of a vial to an interior volume of a reservoir; a second needle having a fluid path for communicating between atmosphere and the interior volume of the vial; and a bias member connected between an end of the reservoir and a plunger head positioned in the reservoir, the bias member for providing a force behind the plunger head as the plunger head is moved within the reservoir to transfer fluidic media from the interior volume of the vial to the interior volume of the reservoir; the bias member and the transfer guard configured to equalize pressure relative to atmosphere in the interior volume of the vial in a case where the second needle communicates between atmosphere and the interior volume of the vial and the plunger head is moved within the reservoir to transfer fluidic media from the interior volume of the vial to the interior volume of the reservoir.
