Disclosed is a fluid transfer system for transferring a substance from one vessel to another vessel while avoiding leakage of liquid and gas contaminants. The transfer system includes a needle safe design that is facilitated by a housing that shrouds a tip of a fluid transfer cannula such that the cannula tip is not exposed for inadvertent puncture. This feature may also be enhanced by use of a blunt tipped cannula. The fluid transfer system permits multiple access by enabling the easy swabbing of a septum prior to use.

1. A medical substance receiver device adapted to removably couple to a medical substance transfer device, the transfer device including: (1) a transfer housing defining an interior chamber;(2) a first septum movably disposed in a distal end of the chamber in a sealing relationship with the chamber, the first septum having a distal surface substantially flush with a distal edge of the transfer housing;(3) a cannula extending through the chamber, and wherein, when the transfer device is uncoupled from the receiver device, a distal tip of the cannula is positioned proximal of the distal edge of the transfer housing;(4) a biasing member inside the chamber, the biasing member adapted to bias the first septum toward the distal end of the chamber,the receiver device comprising:(1) a receiver housing defining an interior passageway, wherein the interior passageway is in communication with a distal tip of the cannula when the transfer device and receiver device are coupled to one another;(2) a second septum disposed in a proximal region of the housing, the second septum having a proximal surface adjacent a proximal edge of the housing, wherein the proximal surface of the second septum is in juxtaposed contact with the distal surface of the first septum when the transfer device and receiver device are coupled to one another and wherein the second septum provides a barrier to prevent fluid from escaping from the interior passageway of the receiver housing;(3) a wiping member disposed in the receiver housing distal of the second septum, the wiping member adapted to wipe the cannula during uncoupling of the receiver device and transfer device, wherein the second septum and the wiping member define a space therebetween, the space adapted to retain fluid. 2. A system as in claim 1, wherein the first and second septums contact the cannula when the transfer device and receiver device are coupled to one another. 3. A system as in claim 1, the wiping member comprises a third septum. 4. A system as in claim 1, wherein the wiping member comprises a duckbill valve. 5. A system as in claim 1, wherein a distal tip of the cannula is positioned inside the chamber in the first housing when the transfer device and receiver device are uncoupled from one another. 6. A system as in claim 1, wherein the distal tip of the cannula is at least partially positioned inside the first septum when the transfer device and receiver device are uncoupled from one another. 7. A system as in claim 1, wherein the second septum has a slit for passage of the cannula therethrough, and wherein the second septum comprises a resilient material that provides bulk resilience to maintain a closed, default state of the slit. 8. A system as in claim 1, wherein first septum, second septum, and the wiping member all wipe the cannula during uncoupling of the transfer device from the receiver device.
