Abstract

Various aspects of the subject disclosure relate to a compounder system having a cartridge that includes fluid pathways controllable by valves of the cartridge. A pump component within the cartridge is actuable to move fluid through the controllable fluid pathways. The cartridge includes a dry disconnect shuttle valve comprising a male portion and a female portion, the dry disconnect shuttle valve configured for needleless use and maintaining a leak-free seal at disconnection with the at least one diluent port comprising the female portion of the dry disconnect shuttle valve.

First claim

What is claimed is:

1. A compounder system, comprising:
a cartridge having:
a plurality of controllable fluid pathways fluidly coupled to at least one diluent port and a receiving container port;
a pump configured to pump a fluid within the plurality of controllable fluid pathways, the pump comprising a tapered grasping handle;
a grasping mechanism configured to grasp and actuate the tapered grasping handle to pump the fluid, the grasping mechanism having a tapered surface configured to engage the tapered grasping handle with reduced or no clearances between the tapered surface of the grasping mechanism and the tapered grasping handle; and
a dry disconnect shuttle valve comprising a male portion and a female portion, the dry disconnect shuttle valve configured for needleless use and maintaining a leak-free seal at disconnection, wherein the at least one diluent port comprises the female portion of the dry disconnect shuttle valve.

2. The compounder system of claim 1 , further comprising tubing coupled between the male portion of the dry disconnect shuttle valve and a diluent container.

3. The compounder system of claim 2 , wherein the male portion comprises a side port configured to be extended into the female portion to form a fluid pathway between the male portion and the female portion.

4. The compounder system of claim 1 , further comprising a filter disposed in a fluid pathway between the cartridge and a receiving container.

5. The compounder system of claim 1 , wherein the pump is a syringe pump comprising a syringe plunger having the tapered grasping handle.

6. The compounder system of claim 5 , wherein the syringe plunger further comprises at least one o-ring.

7. The compounder system of claim 6 , wherein the grasping mechanism comprises a claw mechanism.

8. The compounder system of claim 1 , further comprising:
a connector for a receiving container; and
tubing extending from the receiving container port of the cartridge to the connector.

9. The compounder system of claim 8 , further comprising the receiving container connected to the connector, wherein the pump comprises a pump mechanism that is actuable by the compounder system to pump fluid through at least one of the plurality of controllable fluid pathways to the receiving container.

10. The compounder system of claim 8 , further comprising:
a filter disposed at an interface between the connector and the tubing.

11. The compounder system of claim 10 , wherein the filter is disposed within a housing of the connector.

12. The compounder system of claim 10 , wherein the filter is disposed in a filter element that is coupled at a first end to the tubing and at a second end to the connector.

13. The compounder system of claim 1 , wherein the grasping mechanism is a claw with a first arm and a second arm.

14. The compounder system of claim 13 , wherein the tapered surface of the grasping mechanism comprises a tapered surface of the first arm and a tapered surface of the second arm.

15. The compounder system of claim 13 , wherein the claw is configured to be mechanically actuated to grasp the grasping handle.

16. The compounder system of claim 1 , wherein mating of the tapered surface of the grasping mechanism and the tapered grasping handle is configured to reduce or eliminate backlash.
