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.

Abstract
In certain embodiments, a vial adaptor for removing liquid contents from a vial comprises a housing and a bag. In some embodiments, an initial volume of a regulating fluid can be contained within the bag. In some embodiments, the regulating fluid flows into the vial as liquid is removed from the vial via the adaptor, thereby regulating pressure within the vial. In some embodiments, a vial adaptor is coupled with the vial in order to remove the liquid. In some embodiments, as the liquid is removed from the vial via the adaptor, the bag expands, and in other embodiments, the bag contracts.
