Pressure-regulating 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. |

1. A pressure-regulating adaptor, comprising:
a housing assembly configured to connect with a vial that contains a volume of medical fluid and is sealed with a septum; an extractor channel formed in the housing assembly and in fluid communication with a medical connector interface, the position of the extractor channel being substantially fixed with respect to the housing assembly; a regulator channel formed in the housing assembly; a filter configured to allow a regulating fluid to enter the regulator channel and to inhibit contaminants from entering the regulator channel; an enclosure in communication with the regulator channel, the enclosure configured to expand and contract with changes in the volume of medical fluid in the vial; and wherein the enclosure is outside the vial when the housing assembly is connected with the vial. |
