Abstract

An exemplary vial adapter may include a moveable member, an elongated member with a first passage, a second passage coupled to an expandable first reservoir, and a third passage coupled to an expandable second reservoir. In a first orientation of an exemplary vial adapter, a fluid may be directed through the first passage into the first reservoir or the second reservoir. In a second orientation of an exemplary vial adapter, a fluid may be drawn through the first passage and a fluid drawn through an air passage into the second passage. In a second orientation of an exemplary vial adapter, a fluid may be directed through the first passage and through the third passage into the second reservoir. In a first orientation of an exemplary vial adapter, a moveable member may be activated to direct a fluid from the second reservoir through the third passage.

First claim

What is claimed is:

1. A vial adaptor for coupling with a vial, the vial adaptor comprising:
a medical connector interface;
an elongated member configured to extend into the vial upon coupling the vial adaptor with the vial;
an expandable first reservoir;
an expandable second reservoir;
a first passage between the medical connector interface and the elongated member;
a second passage between a chamber and the elongated member, the first reservoir coupled to the chamber through a first one-way valve that permits flow from the chamber into the first reservoir, and an air passage coupled to the chamber through a second one-way valve that permits flow from the air passage into the chamber; and
a third passage between the second reservoir and the elongated member.

2. The vial adaptor of claim 1 , wherein the second passage comprises a valve.

3. The vial adaptor of claim 2 , wherein the valve is orientation dependent.

4. The vial adaptor of claim 2 , further comprising a filter between the chamber and the valve.

5. The vial adaptor of claim 4 , wherein the filter is hydrophobic.

6. The vial adaptor of claim 1 , wherein the second reservoir is resilient.

7. The vial adaptor of claim 1 , further comprising a moveable member configured to direct a fluid from the second reservoir.

8. The vial adaptor of claim 1 , further comprising a housing.

9. The vial adaptor of claim 8 , further comprising a housing vent configured to couple an inner portion of the housing with an ambient environment.

10. The vial adaptor of claim 9 , wherein the air passage is fluidly coupled to the inner portion of the housing comprising the housing vent.

11. A method for communicating fluid through a vial adaptor, the method comprising:
coupling a medical connector to a vial using a vial adaptor having an expandable first reservoir and an expandable second reservoir;
directing fluid from a medical connector into a vial when the vial adaptor is in a first orientation where the vial adaptor is in fluid communication with a gas in the vial, permitting the gas displaced from the vial to enter the first reservoir, and permitting a liquid displaced from the vial to enter the second reservoir;
drawing a liquid from the vial into the medical connector when the vial adaptor is in a second orientation, opposite the first orientation, where the vial adaptor is in fluid communication with the liquid in the vial, and permitting a gas to be drawn from an ambient environment through an air passage of the vial adaptor into the vial; and
directing a liquid from the medical connector into the vial when the vial adaptor is in the second orientation, and permitting a liquid displaced from the vial to enter the second reservoir.

12. The method of claim 11 , further comprising directing the fluid from the second reservoir into the vial when the vial adaptor is in the first orientation.

13. The method of claim 12 , wherein directing the fluid from the second reservoir into the vial comprises compressing the second reservoir.

14. The method of claim 11 , further comprising obstructing a fluid flow between the first reservoir and the vial when the vial adaptor is in the second orientation.

15. The method of claim 11 , further comprising obstructing a fluid flow from the vial to the air passage when the vial adaptor is in the second orientation.

16. The method of claim 11 , further comprising filtering a gas drawn through the air passage.

17. The method of claim 11 , further comprising permitting a fluid to be drawn from the second reservoir into the vial when the vial adaptor is in the second orientation.
