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.
Claims11
A pressure regulating adaptor for coupling with a vial, the adaptor comprising:
- a bladder having an interior filled with a pre-pressurized, sterilized gas;
- a piercing member configured to be inserted in the vial, the piercing member defining a distal regulator aperture and a distal extractor aperture;
- a first channel for removing fluid from the vial, at least a portion of the first channel extending from the distal extractor aperture and through the piercing member;
- and
- a second channel configured to permit at least some of the sterilized gas to move from the bladder through the distal regulator aperture to the vial as fluid is removed from the vial via the first channel;
- wherein the second channel is selectively sealed by a removable cover configured to be placed over the distal regulator aperture, the removable cover comprising a tab configured to catch on a septum as the piercing member is inserted through the septum into the vial, causing the tab to be removed from the distal regulator aperture.
