## Abstract

The present invention provides a receptacle used in a passive drug delivery system. The receptacle includes first flow path for supplying along a fluid conduit a medical liquid, second flow path for introducing the medical liquid into a container containing a beneficial agent, third flow path for delivering a mixed solution containing the medical liquid and agent, and a guide valve for controlling the flow path by closing or opening the flow path.

## Claims

### Claim 1

A device disposed in a fluid conduit for supplying a medical liquid comprising:
a receptacle adapted to receive an apparatus to deliver a passively reconstituted beneficial agent to a patient;
a first flow path adapted to supply the medical liquid along the fluid conduit;
an upper chamber inside the receptacle and a space formed around a cannula by a member to hold the cannula, the upper chamber adapted to introduce the medical liquid into a container containing the beneficial agent, wherein the medical liquid and the beneficial agent from a mixed solution;
an opening to introduce the solution formed at the top of the cannula, an opening for delivery formed at the bottom of the cannula, and a lower chamber inside the receptacle wherein the mixed solution is delivered;
the mixed solution is delivered;
a guide valve means located between the first flow path and the second flow path for controlling the flow paths by closing or opening communication between the first flow path and the second flow path;
a cannula extending from the third chamber into the apparatus to deliver the passively reconstituted beneficial agent to a patient; and
a space formed around the cannula extending from and in fluid communication with the second chamber into the apparatus to deliver the passively reconstituted beneficial agent to a patient.

### Claim 2 (depends on 1)

The device of claim 1, wherein wherein both the upper and lower chambers are further divided into a front chamber and a rear chamber so that the upper rear chamber and the lower rear chamber serve for the second flow path means and for the third flow path means, respectively, and wherein the guide valve closes or opens communications between the upper front and upper rear chamber, and the valve closes or opens communications between the upper front chamber and the lower front chamber, respectively.

### Claim 3 (depends on 2)

The device of claim 2, wherein a fixing member for the container is disposed at a mount on the second flow path means.

### Claim 4 (depends on 1)

The device of claim 1, wherein a fixing member for the container is disposed at a mount on the second flow path means.

### Claim 5 (depends on 1)

The device of claim 1 wherein a fixing member for the container is disposed at a mount on the second chamber.

### Claim 6

A receptacle disposed in a fluid conduit for supplying a medical liquid, the receptacle adapted to receive an apparatus to deliver a passively reconstituted beneficial agent to a patient, the receptacle comprising:
a first chamber in communication with an inlet;
a second chamber in communication with the apparatus to deliver a passively reconstituted beneficial agent to a patient;
a third chamber in downstream communication with the apparatus to deliver a passively reconstituted beneficial agent to a patient;
a fourth chamber in communication with an outlet;
guide valve means for establishing communication between the first chamber and the fourth chamber while closing communication between the second chamber and the third chamber;
the guide valve means further being for establishing communication between the first chamber and the second chamber while establishing communication between the third chamber and the fourth chamber;
a cannula extending from the third chamber into the apparatus to deliver the passively reconstituted beneficial agent to a patient; and
a space formed around the cannula extending from and in fluid communication with the second chamber into the apparatus to deliver the passively reconstituted beneficial agent to a patient.

### Claim 7 (depends on 6)

The receptacle of claim 6 wherein a fixing member for the container is disposed at a mount on the second chamber.
