In certain embodiments, a vial adaptor for removing liquid contents from a vial comprises a piercing member and a bag. The bag can be contained within the piercing member such that the bag is introduced to the vial when the vial adaptor is coupled with the vial. In some embodiments, the bag expands within the vial as liquid is removed from the vial via the adaptor, thereby regulating pressure within the vial. In other embodiments, a vial comprises a bag for regulating pressure within the vial as liquid is removed therefrom. 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 within the vial, and in other embodiments, the bag contracts within the vial.

1. A pressure regulating adaptor for coupling with a vial, the adaptor comprising: a housing portion configured to couple with the vial, the housing portion comprising at least a portion of a regulator channel configured to permit regulating fluid to pass therethrough and at least a portion of an extractor channel configured to permit medicinal fluid to pass therethrough;a regulating enclosure portion comprising an interior volume in fluid communication with the regulator channel, wherein the regulating enclosure portion is configured to move between a first orientation in which at least a portion of the regulating enclosure portion is at least partially unexpanded or folded and a second orientation in which at least a portion of the regulating enclosure portion is at least partially expanded or unfolded when medicinal fluid is withdrawn from the vial via the extractor channel, and wherein the regulating enclosure portion is positioned outside the vial, when the adaptor is coupled with the vial;an input port disposed between the regulator channel and ambient, the input port comprising a one-way valve configured to permit ambient air to flow into the regulator channel and to prevent fluid from flowing out of the regulator channel to ambient; anda filter configured to filter ambient air entering the regulator channel via the input port. 2. The adaptor of claim 1, wherein the regulator channel is configured to permit ambient air to flow into the regulator channel as medicinal fluid is withdrawn from the vial, thereby equalizing pressure within the vial. 3. The adaptor of claim 1, further comprising a regulator filter configured to filter ambient air entering the regulating enclosure portion. 4. The adaptor of claim 1, further comprising a cap connector configured to couple the adaptor with the vial. 5. The adaptor of claim 1, further comprising a medical connector configured to couple the adaptor with a medical device, wherein the medical device is in fluid communication with the extractor channel when the medical device is coupled to the medical connector. 6. The adaptor of claim 5, wherein the medical device is configured to extract fluid from or inject fluid into the vial. 7. The adaptor of claim 1, wherein the regulating enclosure portion is constructed from a material system comprising a flexible material and a rigid material. 8. A pressure regulating adaptor for coupling with a vial, the adaptor comprising: a housing portion configured to couple with the vial, the housing portion comprising at least a portion of a regulator channel configured to permit regulating fluid to pass therethrough and at least a portion of an extractor channel configured to permit medicinal fluid to pass therethrough;a regulating enclosure portion comprising an interior volume in fluid communication with the regulator channel, the regulating enclosure portion configured to regulate pressure within the vial when fluid is withdrawn from the vial while the adaptor is coupled with the vial; andan input port disposed between the regulator channel and ambient, the input port comprising a one-way valve configured to permit ambient air to flow into the regulator channel and to prevent fluid from flowing out of the regulator channel to ambient;wherein the regulating enclosure portion is positioned outside the vial when the adaptor is coupled with the vial. 9. The adaptor of claim 8, wherein the input port and the regulating enclosure portion are disposed at opposite ends of the adaptor. 10. The adaptor of claim 8, wherein a single housing comprises the housing portion, the regulating enclosure portion, and the input port. 11. The adaptor of claim 8, further comprising a piercing member that defines a regulator aperture and a distal portion of the regulator channel. 12. The adaptor of claim 8, wherein the extractor channel extends between a piercing member and a medical connector configured to couple with a syringe. 13. The adaptor of claim 8, wherein the regulating enclosure portion comprises a bag in substantially airtight engagement with an inner side wall of the regulating enclosure portion. 14. The adaptor of claim 13, wherein the bag comprises a flexible material capable of expanding and contracting. 15. The adaptor of claim 13, wherein the bag comprises a substantially impervious material. 16. A pressure regulating adaptor for coupling with a vial, the adaptor comprising: a housing portion configured to couple with the vial, the housing portion comprising at least a portion of a regulator channel configured to permit regulating fluid to pass therethrough and at least a portion of an extractor channel configured to permit medicinal fluid to pass therethrough;a regulating enclosure portion comprising an interior volume in fluid communication with the regulator channel, the regulating enclosure portion configured to regulate pressure within the vial when fluid is withdrawn from the vial while the adaptor is coupled with the vial; andan input port disposed between the regulator channel and ambient, the input port comprising a one-way valve configured to permit ambient air to flow into the regulator channel and to prevent fluid from flowing out of the regulator channel to ambient,wherein the adaptor is configured such that as fluid enters the vial via the extractor channel, fluid is forced into the regulating enclosure portion via the regulator channel. 17. A method of manufacturing a pressure regulating adaptor for coupling with a vial, the method comprising: providing a pressure regulating adaptor comprising: a housing portion configured to couple with the vial, the housing portion comprising at least a portion of a regulator channel configured to permit regulating fluid to pass therethrough and at least a portion of an extractor channel configured to permit medicinal fluid to pass therethrough, anda regulating enclosure portion comprising an interior volume in fluid communication with the regulator channel, the regulating enclosure portion configured to regulate pressure within the vial when fluid is withdrawn from the vial while the adaptor is coupled with the vial;providing a one-way valve configured to permit fluid to flow in a permitted direction and to prevent fluid from flowing opposite the permitted direction; andconnecting the one-way valve to an input port of the pressure regulating adaptor, such that the input port permits ambient air to flow into the regulator channel and substantially prevents fluid from flowing out of the regulator channel to ambient;wherein the regulating enclosure portion is positioned outside the vial when the adaptor is coupled with the vial. 18. The method of claim 17, further comprising: providing a filter; andconnecting the filter to the input port, such that the filter filters ambient air entering the regulator channel via the input port. 19. The method of claim 17, further comprising: providing the regulating enclosure portion by connecting a flexible material in substantially airtight engagement with a rigid portion of the regulating enclosure portion.
