1. An apparatus configured to aid in accessing contents of a vial, the apparatus comprising:

  • a housing portion comprising;

    a medical connector interface configured to couple the apparatus with a medical device to place an interior of the medical device in fluid communication with an interior of the vial; and

    a substantially hollow sheath surrounding a chamber;

    an insertion member movable independent of the housing portion and configured to enter the chamber;

    a locking mechanism configured to secure the housing portion to the insertion member, wherein the locking mechanism comprises a ridge connected to the housing portion so that the ridge is formed integrally with the sheath, wherein the ridge is moved into an open position as the insertion member is entering the chamber and is returned to a closed position by a springing action thereafter, wherein in the closed position, the springing action forces the ridge against a portion of the insertion member to stabilize the insertion member inside the chamber;

    a regulator channel in the insertion member, wherein the regulator channel is configured to permit ambient air to flow into the regulator channel in response to medicinal fluid being withdrawn from the vial, thereby equalizing pressure within the vial;

    a piercing member configured to pierce a septum of the vial;

    a first filter, configured to absorb a first group of contaminants in a liquid state or a vapor state; and

    a second filter, distinct from the first filter, configured to absorb a second group of contaminants at least partially distinct from the first group of contaminants.
