Air-filtering vial adaptors and methods

摘要

In certain embodiments, a vial adaptor for removing liquid contents from a vial comprises a housing and a bag. In some embodiments, an initial volume of a regulating fluid can be contained within the bag. In some embodiments, the regulating fluid flows into the vial as liquid is removed from the vial via the adaptor, thereby regulating pressure within the vial. 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, and in other embodiments, the bag contracts.

主权项

1. A pressure regulating adaptor for coupling with a vial having an interior filled with medicinal fluid, the adaptor comprising:
a housing portion configured to couple with the vial, the housing portion comprising at least a portion of a regulator channel configured to permit regulating fluid to pass therethrough and at least a portion of an extractor channel configured to permit medicinal fluid to pass therethrough; a piercing member that includes a regulator aperture and through which at least a portion of the regulator channel extends; a port disposed between the regulator channel and ambient; a first filter in fluid communication with the interior of the vial when the adaptor is coupled with the vial, wherein the first filter is configured to filter ambient air passing through the port; and a second filter in fluid communication with the regulator channel and configured to filter air, wherein the second filter is connected to the housing portion and spatially separated from the first filter, and wherein the second filter is separated from the interior of the vial by at least one membrane when the adaptor is coupled with the vial.
