Abstract

The present invention is directed to a device for sterile coupling and decoupling of a first solution system to a second solution system. The first system has a resealable member so as to allow access into the system. The device includes a housing for receiving the resealable member so as to provide a fluid tight cooperating engagement with the resealable member. A penetrable barrier is positioned in the housing across from the resealable member. A conduit in flow communication with the second system is adapted for sterile penetration of the barrier and the resealable member. An inlet and outlet duct provides a passageway between the barrier and the resealable member. The inlet is adapted for fluid flow from a source of sterilizing fluid and optionally a sterile rinsing fluid. The outlet duct receives the sterilizing fluid after is passes across and sterilizes the resealable member facing the barrier.

Claims

1. A device for sterile coupling and decoupling of a first system to a second system, the first system having a resealable member so as to allow access into the system, the device comprising:

a housing configured and dimensioned for receiving and cooperating with the resealable member so as to provide a fluid tight cooperating engagement when the resealable member enters said housing;

barrier means disposed within said housing and positioned across from said resealable member;

a conduit connected to the second system and adapted for sterile penetration of said barrier and said resealable member; and

an inlet duct and an outlet duct disposed through said housing and disposed between said barrier means and the resealable member when positioned within said housing, said inlet duct adapted for fluid flow from a source of sterilizing fluid, and said outlet duct adapted for fluid flow to receive said sterilizing fluid after passing across the resealable member facing said barrier means.

2. The device of claim 1 wherein said inlet duct, said outlet duct, said barrier means and said resealable member when positioned in said housing form a fluid flow passageway.

3. The device of claim 2 further comprising a source of sterile rinsing fluid adapted for flow connection to the inlet duct so as to flush residual sterilizing fluid from the fluid flow passageway.

4. The device of claim 1 wherein said conduit is a dual lumen conduit.

5. The device of claim 4 wherein said dual lumen conduit comprises a solution transfer lumen and a system venting lumen.

6. A device for sterile coupling and decoupling of a drug container to a delivery system, the container having an open end and a puncturable seal adapted to seal the open end and to allow access into the open end, the device comprising;

a housing configured and dimensioned for receiving and cooperating with the container so as to provide a fluid tight cooperating engagement when the sealed open end enters said housing;

barrier means disposed within said housing and positioned across from said sealed open end;

a conduit connected to the delivery system and adapted for sterile penetration of said barrier; and

an inlet duct and an outlet duct disposed through said housing and disposed between said barrier means and the sealed open end of the container when positioned within said housing, said inlet duct adapted for fluid flow from a source of sterilizing fluid, and said outlet duct adapted for fluid flow to receive said sterilizing fluid after passing across the sealed open end facing said barrier means.

7. The device of claim 6 wherein said conduit is a dual lumen piercing device having a fluid transfer lumen and a system venting lumen.

8. The device of claim 6 wherein the drug container is a flexible container and the conduit is a single lumen piercing device.
