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 needle extending from a cartridge body and fluidly coupled to at least one of the controllable fluid pathways. A vial puck is provided for attachment to a vial to be fluidly coupled to the cartridge by the needle. The vial puck may include a hygroscopic member to absorb fluid from the needle to ensure a dry disconnect. A shuttle valve may also be provided.

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, wherein the at least one diluent port comprises a female portion of a dry disconnect shuttle valve, wherein the pump is a syringe pump comprising a syringe plunger having a tapered grasping handle; and
a grasping mechanism configured to grasp and actuate the syringe plunger to pump the fluid, wherein the grasping mechanism has 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.

2. The compounder system of claim 1 , further comprising a male portion of the dry disconnect shuttle valve and 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 syringe plunger further comprises at least one o-ring.

6. The compounder system of claim 5 , wherein the grasping mechanism comprises a claw mechanism.

7. The compounder system of claim 1 , further comprising:
a connector for a receiving container;
tubing extending from the receiving container port of the cartridge to the connector; and
a filter disposed at an interface between the connector and the tubing.

8. The compounder system of claim 7 , 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.

9. The compounder system of claim 7 , wherein the filter is disposed within a housing of the connector.

10. The compounder system of claim 7 , wherein the filter is disposed in a filter element that is coupled at a first end of the filter element to the tubing and at a second end of the filter element to the connector.

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

12. The compounder system of claim 11 , wherein the tapered surface of the grasping mechanism comprises a tapered surface of the first arm and a tapered surface of the second arm.

13. The compounder system of claim 11 , wherein the claw is spring loaded and configured to be actuated by the spring to grasp the grasping handle.

14. The compounder system of claim 11 , wherein the claw is configured to be mechanically actuated to grasp the grasping handle.

15. The compounder system of claim 11 , wherein the claw comprises a pitchfork design configured to grasp the grasping handle without movement of the first and second arms relative to each other.

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.
