1. A vial access device configured to aid in accessing contents of a vial containing a volume of a medical fluid, the device comprising:
- a piercing member configured to pierce a septum of the vial;
a distal extractor aperture on the piercing member configured to permit withdrawal of the medical fluid from the vial when the device is coupled to the vial, wherein the distal extractor aperture leads to an extractor channel that is placed in fluid communication with an interior of the vial when the device is coupled to the vial;
a distal regulator aperture configured to permit fluid communication between the vial and the device when the device is coupled to the vial, wherein the distal regulator aperture leads to a regulator channel that is placed in fluid communication with the interior of the vial when the device is coupled to the vial;
a medical connector interface in fluid communication with the extractor channel, wherein the medical connector interface is configured to interface with a syringe that has no exposed needle; and
a reservoir in fluid communication with the regulator channel, the reservoir containing an initial volume of a regulating fluid, the reservoir configured to contract when the medical fluid is withdrawn from the vial via the extractor channel,wherein the reservoir is configured to supply at least some of the initial volume of regulating fluid to the vial via the regulator channel, thereby facilitating withdrawal of the medical fluid from the vial and compensating for such withdrawal of the medical fluid from the vial.

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.

17. A method of manufacturing a device configured to couple with a vial containing a medical fluid, the method comprising:
-
forming a housing member, the housing member including a distal extractor aperture configured to permit withdrawal of the medical fluid from the vial when the device is coupled to the vial, wherein at least a portion of an extractor channel and at least a portion of a regulator channel pass through the housing member; and placing a reservoir in fluid communication with the regulator channel, the reservoir containing an initial volume of a regulating fluid, the reservoir configured to contract when the medical fluid is withdrawn from the vial via the extractor channel, wherein the housing member includes at least one piercing member having a distal regulator aperture leading to the regulator channel, wherein the at least one piercing member is configured to pierce a septum of the vial and thereby be placed in fluid communication with an interior of the vial when the device is coupled with the vial; wherein the reservoir is configured to supply at least some of the initial volume of regulating fluid to the vial via the regulator channel, thereby facilitating withdrawal of the medical fluid from the vial and compensating for such withdrawal of the medical fluid from the vial; and wherein the extractor channel is in fluid communication with a medical connector interface configured to interface with a syringe that has no exposed needle. - View Dependent Claims (18, 19)

20. A vial access system configured to aid in accessing contents of a vial containing a volume of a medical fluid, the system comprising:
-
a piercing member configured to pierce a septum of the vial; a distal extractor aperture on the piercing member configured to permit withdrawal of the medical fluid from the vial as a result of the system being coupled to the vial, wherein the distal extractor aperture leads to an extractor channel that is configured to be placed in fluid communication with an interior of the vial as a result of the system being coupled to the vial; a distal regulator aperture configured to permit fluid communication between the vial and the system as a result of the system being coupled to the vial, wherein the distal regulator aperture leads to a regulator channel that is configured to be placed in fluid communication with the interior of the vial as a result of the system being coupled to the vial; and a reservoir in fluid communication with the regulator channel, the reservoir containing an initial volume of a regulating fluid, the reservoir configured to decrease in volume as a result of the medical fluid being withdrawn from the vial via the extractor channel; wherein the initial volume of regulating fluid comprises sterilized gas configured to remain sterile up through coupling the system with the vial; and wherein the reservoir is configured to supply at least some of the initial volume of regulating fluid to the vial via the regulator channel, thereby facilitating withdrawal of the medical fluid from the vial and compensating for such withdrawal of the medical fluid from the vial. - View Dependent Claims (21, 22, 23)
