Abstract

An exemplary pharmaceutical compounding system and device for mixing materials from at least two distinct material sources can include a transfer set and junction structure that has a junction body, a first inlet port located at a first portion of the junction body, a second inlet port located at a second portion of the junction body, and an outlet port located at a third portion of the junction body. The junction structure can be configured to mix fluid received from both the first inlet port and second inlet port and to deliver the fluid to the outlet port. The junction structure can also include attachment structure located on the junction body and configured to attach the junction structure to the housing of the compounding device at a location downstream of a pump system.

First claim

What is claimed is:

1. A junction structure for use in a pharmaceutical compounding device, the compounding device having a housing that supports a pump system and a valving mechanism, the junction structure comprising:
a junction body;
a first inlet port located at a first portion of the junction body;
a second inlet port located at a second portion of the junction body;
an outlet port located at a third portion of the junction body;
a mixing chamber located between the outlet port and both the first inlet port and second inlet port, the mixing chamber configured to mix fluid received from both the first inlet port and second inlet port and to deliver the fluid to the outlet port;
an attachment structure located on the junction body and configured to attach the junction structure to the housing of the compounding device; and
a standoff structure extending from a lower surface of the junction body and configured to space the junction body from a surface of the compounding device to which the junction body is to be attached.

2. The junction structure of claim 1 , wherein
the first inlet port defines a first flowpath for fluid and the second inlet port defines a second flowpath for fluid, the first flowpath defined by the first inlet port has a micro cross-sectional area taken normal to the first flowpath, the second flowpath defined by the second inlet port has a macro cross-sectional area taken normal to the second flowpath, and the micro cross-sectional area is less than the macro cross-sectional area.

3. The junction structure of claim 2 , wherein an outlet flowpath defined by the outlet port has an outlet cross-sectional area taken normal to the outlet flowpath that is equal to or greater than the macro cross-sectional area.

4. The junction structure of claim 1 , wherein
the attachment structure includes at least one clip extending from a lower surface of the junction body and configured to mate with a corresponding locking structure on the housing of the compounding device.

5. The junction structure of claim 4 , wherein
the at least one clip includes a first clip and a second clip, and
the attachment structure includes a first handle extending away from a top surface of the junction body and away from the first clip, and a second handle extending away from the top surface of the junction body and away from the second clip.

6. The junction structure of claim 5 , wherein
the first handle is configured to cause the first clip to move relative to the lower surface of the junction body when an amount of force is applied to the first handle by a user, and the second handle is configured to cause the second clip to move relative to the lower surface of the junction body when an amount of force is applied to the second handle by the user.

7. The junction structure of claim 1 , further comprising
a manifold configured for attachment to the valving mechanism of the compounding device, a macro line extending from the manifold to the pump system and to the junction body, a micro line extending from the manifold to the pump system and to the junction body, wherein the junction body, first inlet port, second inlet port and mixing chamber are located downstream of the pump system and configured such that fluid from the micro line and macro line are caused to mix at the mixing chamber after passing the pump system.

8. The junction structure of claim 7 , wherein the macro line and micro line are in fluid isolation from each other upstream of the junction body.

9. The junction structure of claim 8 , wherein the manifold includes a micro channel and a macro channel, and a cross-sectional area taken normal to a longitudinal axis of the micro channel is less than a cross-sectional area taken normal to a longitudinal axis of the macro channel.

10. The junction structure of claim 1 , wherein
the junction body is configured as a junction plate, and
the first inlet port, the second inlet port, the outlet port, and the mixing chamber are configured as a junction line, and the junction plate includes a recess configured to receive the junction line.

11. The junction structure of claim 10 , wherein
the junction plate is a single piece integral structure, and
the junction line is a single piece integral structure configured for attachment to the junction plate.

12. The junction structure of claim 10 , wherein the junction plate includes a locking structure configured to secure the junction line in the recess of the junction plate.

13. A junction structure for use in a pharmaceutical compounding device, the compounding device having a housing that supports a pump system and a valving mechanism, the junction structure comprising:
a junction body;
a first inlet port located at a first portion of the junction body;
a second inlet port located at a second portion of the junction body;
an outlet port located at a third portion of the junction body;
a mixing chamber located between the outlet port and both the first inlet port and second inlet port, the mixing chamber configured to mix fluid received from both the first inlet port and second inlet port and to deliver the fluid to the outlet port;

an attachment structure located on the junction body and configured to attach the junction structure to the housing of the compounding device; and
a manifold configured for attachment to the valving mechanism of the compounding device, a macro line extending from the manifold to the pump system and to the junction body, a micro line extending from the manifold to the pump system and to the junction body, wherein the junction body, first inlet port, second inlet port and mixing chamber are located downstream of the pump system and configured such that fluid from the micro line and macro line are caused to mix at the mixing chamber after passing the pump system,
wherein the macro line and micro line are in fluid isolation from each other upstream of the junction body, and
wherein the manifold includes a micro channel and a macro channel, and a cross-sectional area taken normal to a longitudinal axis of the micro channel is less than a cross-sectional area taken normal to a longitudinal axis of the macro channel.

14. The junction structure of claim 13 , wherein
the first inlet port defines a first flowpath for fluid and the second inlet port defines a second flowpath for fluid, the first flowpath defined by the first inlet port has a micro cross-sectional area taken normal to the first flowpath, the second flowpath defined by the second inlet port has a macro cross-sectional area taken normal to the second flowpath, and the micro cross-sectional area is less than the macro cross-sectional area.

15. The junction structure of claim 14 , wherein an outlet flowpath defined by the outlet port has an outlet cross-sectional area taken normal to the outlet flowpath that is equal to or greater than the macro cross-sectional area.

16. The junction structure of claim 13 , wherein
the attachment structure includes at least one clip extending from a lower surface of the junction body and configured to mate with a corresponding locking structure on the housing of the compounding device.

17. The junction structure of claim 16 , wherein
the at least one clip includes a first clip and a second clip, and
