1. A device for transferring fluid to or from a vial, wherein the device comprises:

  • a connector configured to couple the device with a vial, the vial containing a medicinal fluid;

    a septum piercing assembly comprising a distal regulator aperture and a distal extractor aperture, wherein the septum piercing assembly is configured to pierce a septum of the vial and thereby place the distal regulator aperture and the distal extractor aperture in fluid communication with an interior of the vial when the device is coupled with the vial;

    an extractor channel connected to the distal extractor aperture and a proximal extractor aperture, wherein the extractor channel is in fluid communication with the interior of the vial when the device is coupled with the vial, the extractor channel configured to allow fluid to be transferred to or from the vial when the device is coupled with the vial;

    a needle-free medical connector interface connected to the proximal extractor aperture, the needle-free medical connector interface configured to accept a medical device connector;

    a rigid barrier enclosing a reservoir and separating the reservoir from ambient, wherein the reservoir comprises;

    a first portion in fluid communication with the interior of the vial when the device is coupled with the vial; and

    a second portion not in fluid communication with the interior of the vial;

    a flexible barrier located inside the reservoir, wherein the flexible barrier is configured to divide the reservoir into the first and second portions of the reservoir, the flexible barrier configured to move between a first position and a second position when fluid is added to the vial; and

    a regulator channel connected to the distal regulator aperture and a proximal regulator aperture, the regulator channel configured to allow a regulating fluid to move between the interior of the vial and the first portion of the reservoir when the device is coupled with the vial;

    wherein the device is configured such that, when fluid is added to the vial via the extractor channel, regulating fluid moves from the interior of the vial to the first portion of the reservoir via the regulator channel and causes the flexible barrier to expand; and

    wherein the device is configured such that, when medicinal fluid is removed from the vial via the extractor channel after fluid is added to the vial, regulating fluid moves from the first portion of the reservoir to the interior of the vial via the regulator channel and causes the flexible barrier to contract.
