Abstract

An adapter for interconnecting in fluid communication a first connection site and a beneficial agent container having a closure. The adapter includes a plate having first and second connection site sides. A wall extends from the plate from the second connection site side and constructed to surround only the closure. This allows containers having varying sized bodies to be received. A cannula structure is rigidly secured in the plate and defines a flow path extending through the plate. The adapter can be provided in an assembly with the beneficial agent contained or in a drug delivery system.

Claims

1. An adapter for interconnecting in fluid communication a first connection site and a beneficial agent container having a body and closure comprising:

a plate having first and second connection site sides;

a wall extending from the plate from the second connection site side and constructed to engage about only the closure allowing containers having varying sized bodies to be secured therein;

a single, removably covered cannula structure rigidly secured in the plate and defining a flow path extending through the plate; and

a pair of pins extending between the second connection site side and the first connection site side.

2. The adapter of claim 1 further comprising:

a removable cover secured about a portion of the cannula to maintain same in initial sterile condition; and

a tubular single keyway member extending coaxially about the cannula from the first connection site side of the plate, the tubular keyway member positioned coaxially about the cover.

3. The adapter of claim 1 wherein the wall extending from the plate includes a radially outwardly extending lip.

4. A beneficial agent container and adapter assembly, comprising:

a beneficial agent container having a chamber within which can be contained a beneficial agent and a closure having an injection site; and

an adapter configured to interconnect in fluid communication the beneficial agent container and a second connection site, the adapter including a plate having first and second connection site sides, a tubular wall extending from the first connection site side and constructed such that the tubular wall allows containers having varying sized chambers to be secured thereto, a single removable covered cannula structure rigidly secured in the plate and flow path through the plate;

a support secured to the beneficial agent container for removably receiving the adapter; and

a pair of pin extending between the second connection site side and the first connection site side.

5. The beneficial agent container and adapter assembly of claim 4 further comprising:

a single tubular keyway member extending coaxially about the cannula from the first connection site side of the plate.

6. The assembly of claim 5 further comprising:

a pair of detachable covers secured on opposite sides of the plate and about the cannula to maintain same in initial sterile condition, the support interconnecting the cover secured to the second connection site side of the plate and the beneficial agent container; and

a tubular single keyway member extending coaxially about the cannula from the first connection site side of the plate, the tubular keyway member positioned coaxially about the cover secured about the cannula on the first connection site side.

7. The assembly of claim 4 wherein the wall extending from the plate includes a radially outwardly extending lip.

8. The assembly of claim 4 wherein the support includes a cannula receiving member.

9. A beneficial agent delivery system comprising:

a receptacle configured to deliver fluid to a patient, including a first connection site by means of which a beneficial agent can be introduced;

an adapter for interconnecting in fluid communication the first connection site of the delivery system and a beneficial agent container having a closure with a second connection site and a chamber for containing a beneficial agent, the adapter including a plate having first and second connection site sides, a wall extending from the plate from the second connection site side and configured to engage about only the closure of the beneficial agent container, and a single removably covered cannula structure rigidly secured in the plate and having a cannula extending through the plate;

a beneficial agent container having the closure with the second connection site and a chamber within which can be contained a beneficial agent; and

a pair of pins extending between the second connection site side and the first connection site side.

10. The system of claim 9 wherein the wall extending from the plate includes a radially outwardly extending lip.

11. The system of claim 9 including means for removably coupling the adapter to the beneficial agent container prior to inserting the cannula through the closure.

12. An adapter for interconnecting in fluid communication a first connection site and a beneficial agent container having a body and a closure comprising:

a plate having first and second connection site sides;

a wall including a radially outward extending lip which extends from the plate from the second connection site side and constructed to engage about only the closure allowing containers having varying sized bodies to be secured therein;

a single removably covered cannula structure rigidly secured in the plate and defining a flow path extending through the plate;

a pair of removable covers secured on opposite sides of the plate and about the cannula to maintain same in an initial sterile condition;

a tubular keyway member extending coaxially about the cannula from the first connection site side of the plate, the tubular keyway member positioned coaxially about the cover; and

a pair of pins extending between the second connection site side and the first connection site side.

13. A beneficial agent container and adapter assembly, comprising:

a beneficial agent container having a chamber within which can be contained a beneficial agent and a closure having an injection site;

an adapter configured to interconnect in fluid communication the beneficial agent container and a second connection site, the adapter including a plate having first and second connection site sides, a tubular wall including a radially outward extending lip which extends from the first connection site side and constructed such that the tubular wall allows containers having varying sized chambers to be secured thereto, a single removably covered cannula structure rigidly secured in the plate and flow path through the plate;

a support secured to the beneficial agent container for removably receiving the adapter;

a pair of detachable covers secured on opposite sides of the plate and about the cannula to maintain same in initial sterile condition, the support interconnecting the cover secured to the second connection site side of the plate and the beneficial agent container;

a tubular keyway member positioned coaxially about the cover secured about the cannula on the first connection site side; and

a pair of pins extending between the second connection site side and the first connection site side.

14. A beneficial agent delivery system comprising:

a receptacle configured to deliver fluid to a patient, including a first connection site by means of which a beneficial agent can be introduced into the delivery system;

an adapter for interconnecting in fluid communication the first connection site of the delivery system and a beneficial agent container having a closure with a second connection site and a chamber for containing a beneficial agent, the adapter including a plate having first and second connection site sides, a wall including a radially outward extending lip which extends from the plate from the second connection site side and configured to engage about only the closure of the beneficial agent container, and a single removably covered cannula structure rigidly secured in the plate and having a cannula extending through the plate;

a beneficial agent container having the closure with the second connection site and a chamber within which can be contained a beneficial agent.

a tubular single keyway member extending coaxially about the cannula from the first connection site side of the plate.

a pair of pins extending between the second connection site side and the first connection site side and a cover secured about an end of the cannula extending from the second connection site side and being in interference fit with the pins; and

means for removably coupling the adapter to the beneficial agent container prior to inserting the cannula through the closure.
