Abstract
In certain embodiments, a vial adaptor for removing liquid contents from a vial includes 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 includes 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.
Claims31
A vial adaptor capable of removing all or substantially all medicinal fluid from a vial, the adaptor comprising:
- a cap connector configured to couple the adaptor with the vial;
- a medical connector interface configured to couple the adaptor with a medical device;
- a piercing member having a sheath extending from a base of the piercing member, the piercing member configured to be inserted into the vial when the adaptor is coupled with the vial;
- and
- an extractor aperture disposed along a sidewall of the sheath, wherein at least a portion of the extractor aperture has an elongate dimension, such that the extractor aperture is configured to provide a fluid passageway to an extractor channel extending between the extractor aperture and the medical connector interface, even if the extractor aperture is partially obstructed by a septum of the vial when the adaptor is coupled with the vial.
A vial adaptor capable of removing all or substantially all medicinal fluid from a vial, the adaptor comprising:
- a cap connector configured to couple the adaptor with the vial;
- a sheath configured to be inserted into the vial when the adaptor is coupled with the vial;
- a medical connector interface configured to couple the adaptor with a medical device;
- and
- an extractor aperture disposed along a sidewall of the sheath, wherein the extractor aperture is positioned and configured such that the adaptor is capable of removing all or substantially all medicinal fluid from two or more different vials when the two or more different vials vary by size, by cap dimensions, or by size and cap dimensions, thereby affecting the position of the extractor aperture with respect to the septum when the adaptor is coupled with the vial.
A method of withdrawing substantially all medicinal fluid from a vial, the method comprising:
- providing a vial adaptor for coupling with the vial, the adaptor comprising:
- a cap connector configured to couple the adaptor with the vial,
- a medical connector interface configured to couple the adaptor with a medical device,
- a piercing member having a sheath extending from a base of the piercing member, the piercing member configured to be inserted into the vial when the adaptor is coupled with the vial, and
- an extractor aperture disposed along a sidewall of the sheath, the extractor aperture configured to permit medicinal fluid to pass therethrough;
- coupling the adaptor to the vial, such that the extractor aperture is in fluid communication with an interior of the vial;
- and
- withdrawing substantially all medicinal fluid from the vial.
