Abstract

A device for use with an infusion pump is provided. In one exemplary embodiment the device comprises a body portion defining an orifice extending along a first axis, and a first plurality of channels extending along a second axis; and a controller disposed within the orifice and adapted to rotate within the orifice, the controller defining second plurality of channels capable of a fluid tight relationship with the first plurality of channels.

Claims

1. A device for use with an infusion pump, the device comprising:

a body portion defining an orifice extending along a first axis, and a first plurality of channels extending along a second axis; and

a director disposed within the orifice and adapted to rotate within the orifice, the director defining second plurality of channels capable of a fluid tight relationship with the first plurality of channels.

2. The device of claim 1, wherein the director is rotatable between at least two positions.

3. The device of claim 2, wherein:

when the director is in a first one of the positions i) a first and second of the first plurality of channels are coupled to one another via a first one of the second plurality of channels and ii) a third and fourth of the first plurality of channels are coupled to one another via a second one of the second plurality of channels, and

when the director is in a second one of the position i) the first and third of the first plurality of channels are coupled to one another via one of the second plurality of channels and ii) the second and fourth of the first plurality of channels are coupled to one another via the other of the second plurality of channels.

4. The device of claim 1, wherein the body portion is comprised of an upper portion and a lower portion, at least one of the upper and/or lower portions having the first plurality of channels formed in a surface thereof.

5. The device of claim 1, further comprising a seal disposed between an outer surface of the director and the orifice, the seal having a respect number of channels adapted to interface with the first plurality of channels in the body portion and the second plurality of channels in the director.

6. The device of claim 5, wherein the seal is resilient.

7. The device of claim 5, wherein the seal comprises an anti-bacterial agent.

8. The device of claim 1, wherein the director comprises means for indicating a position of director with respect to the body portion.

9. A system for use with a source of fluid to provide the fluid to a user via an infusion set, the system comprising:

an input/output port;

a pump element having an input and an output;

a reservoir to store a quantity of the fluid; and

a director coupled to the input and output of pump element, the reservoir, and input/output port, the director adapted to direct the flow of the fluid i) from the source of fluid via input/output port and into the reservoir via the pump element when the controller is in a first position, and ii) from the reservoir and to the user via the input/output port when the controller is in a second position.

10. The system of claim 9, further comprising a filter disposed between the director and the input of the pump element to filter the fluid i) from the source of fluid when the director is in the first position and ii) from the reservoir when the director is in the second position.

11. The system of claim 10, wherein the filter is used to filter the fluid both when the reservoir is filled with the liquid, and when the fluid is pumped out of the reservoir for infusion into the patient.

12. The system of claim 9, wherein the pump element further comprises a pressure sensor adapted to detect high fluid pressure when the fluid is infused and when the reservoir is refilled.

13. The system of claim 9, further comprising a display and a keypad adapted to preset an amount of the fluid to transfer from the source of fluid to the reservoir.

14. The system of claim 9, further comprising an audio indicator adapted to signal the user that the preset amount of medication has been transferred from the source of fluid to the reservoir.

15. The system of claim 9, further comprising a wireless communication to signal to the user that the preset amount of fluid has been transferred from the source of fluid to the reservoir.

16. The system of claim 9, wherein an operating mode of the system changes based on modifying the position of the director.

17. A medical infusion device for use with a liquid medication, the infusion device comprising:

a pump;

a reservoir coupled to the pump; and

a single fluid port,

wherein in a first mode the fluid port is used to substantially fill the reservoir with the liquid medication, and in a second mode the fluid port if used to dispense the liquid medication to a patient.
