Fluid transfer apparatus with filtered air input
First Claim
1. A device for transferring medicinal fluid between a syringe and a vial, the device comprising:
- a medical connector interface configured to couple the device with the syringe to place an interior of the syringe in fluid communication with an interior of the vial;
a piercing member;
a first filter configured to be in fluid communication with the interior of the vial, wherein the first filter is configured to filter ambient air entering a regulator channel, thereby preventing dust, bacteria, microbes, spores, or other contaminants from entering the vial;
a second filter configured to prohibit passage of liquid or vapors from the regulator channel to ambient;
an insertion member movable independent of the piercing member, the insertion member comprising a regulator aperture connected to the regulator channel, the regulator channel configured to permit ambient air to flow into the regulator channel as the medicinal fluid is withdrawn from the vial, thereby equalizing pressure within the vial; and
an extractor channel configured to permit medicinal fluid to pass therethrough.

Abstract
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.
