1. A vial adaptor for coupling with a vial, the vial adaptor comprising:
a medical connector interface, a vial interface, an expandable first reservoir, an expandable second reservoir, and a first passage extending from the medical connector interface through the vial interface; the first reservoir comprising a second passage extending through the vial interface and a first valve, wherein the first valve permits movement of a fluid into the first reservoir when the vial adaptor is in an upright orientation, and resists movement of a fluid into the first reservoir when the vial adaptor is moved toward an inverted orientation; and the second reservoir comprising a third passage extending through the vial interface to permit a fluid into the second reservoir when the vial adaptor is in the inverted orientation.
