APPARATUS AND METHODS FOR SEQUESTERING FLUIDS EXHAUSTED DURING FLUID TRANSFER
First Claim
1. A liquid transfer connector for providing a liquid transfer path between a donor container having a needle-penetrable septum and a recipient container having a needle-penetrable septum, said connector comprising:
- an enclosure having an interior chamber with a vent;
a transfer needle having an inlet end extending from one side of the interior chamber and an outlet end extending from another side of the chamber, wherein both the inlet end and the outlet end are capable of penetrating a septum on a liquid container;
an exhaust needle having an inlet end adjacent to the outlet end of the transfer needle and an outlet end in the interior chamber; and
a liquid-absorptive mass within the interior chamber, said absortive mass adapted for rapid absorption of liquid entering the interior chamber through the exhaust needle.

Abstract
A liquid transfer connector comprises an enclosure holding a transfer needle and an exhaust needle. A container of donor liquid may be attached to an inlet end of the transfer needle and a container holding a recipient liquid may be attached to an outlet end of the transfer needle and an inlet end of an exhaust needle. The exhaust needle has an outlet end within the connector which releases displaced fluid into an absorbent mass which sequesters the fluid to prevent leakage.

11. A method for transferring a donor liquid into a recipient liquid present in a closed container, said method comprising:
-
establishing a transfer flow path from a source of the donor liquid into the closed container filled with the recipient liquid, establishing an exhaust flow path from the closed container to an absorbent mass; and causing a volume of the donor liquid to flow into the closed container through the transfer flow path which in turn causes a like volume of the recipient liquid to flow through the exhaust flow path into the absorbent mass, wherein the entire volume of the exhausted recipient liquid is absorbed by the absorbent mass. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
