Pressure-regulating devices for transferring medicinal fluid
First Claim
1. A medical adaptor capable of coupling with a sealed container, the medical adaptor comprising:
- a housing comprising;
a medical connector interface having a proximal end;
a piercing member having a distal end configured to penetrate a septum of a vial adaptor when the distal end of the piercing member is pushed against the septum;
an access channel capable of conveying medicinal fluid from a sealed container and extending between the medical connector interface and a distal access port; and
a regulator channel extending between a proximal regulator passageway and a distal regulator aperture; and
a regulator assembly in fluid communication with the proximal regulator passageway, the regulator assembly comprising;
a storage region having a storage volume and a width as measured parallel to a length of the piercing member; and
a flexible enclosure in fluid communication with the proximal passageway, the flexible enclosure capable of transitioning between a contracted configuration wherein the flexible enclosure is positioned within the storage chamber and an expanded configuration wherein at least a portion of the flexible enclosure is positioned outside of the storage chamber, the flexible enclosure having a contracted volume when in the contracted configuration and an expanded volume when in the expanded configuration, the flexible enclosure having a contracted width when in the contracted configuration and an expanded width when in the expanded configuration, the expanded width being different from the contracted width;
wherein the width of the storage region is less than or equal to a distance between the proximal end of the medical connector interface and the distal end of the piercing member.

Abstract
In certain embodiments, a vial adaptor comprises a housing configured to couple the adaptor with a vial, an access channel, a regulator channel, and a regulator assembly. The access channel is configured to facilitate withdrawal of fluid from the vial when the adaptor is coupled to the vial. The regulator channel is configured to facilitate a flow of a regulating fluid from the regulator assembly to compensate for changes in volume of a medical fluid in the vial. In some embodiments, the regulator assembly includes a flexible member configured to expand and contract in accordance with changes in the volume of the medical fluid in the vial. In some embodiments, the flexible member is substantially free to expand and contract. In some embodiments, the flexible member is not partly or completely located in a rigid enclosure.
