Abstract

A pump is disclosed that comprises a primary control unit comprising a first processor and one or more modular pumping units removably docked to the primary control unit. Each modular pumping unit comprises a pumping mechanism and a second processor configured to control the pumping mechanism and communicate with the first processor. The modular pumping unit is configured to manipulate a portion of a fluid delivery set to pump a fluid. The first processor and the second processor are configured to exchange one or more operating parameters when the modular pumping unit is docked to the primary control unit. The modular pumping unit is configured to pump the fluid after being undocked.

Claims

1. A pump comprising:

a primary control unit having a first processor and a plurality of docking stations configured to accept one or more modular pumping units;

a plurality of modular pumping units removably docked to the primary control unit, each modular pumping unit may be docked and undocked in a docking station without docking or undocking another of the modular pumping units, each modular pumping unit comprising;

a pumping mechanism, a first power source, and a second processor configured to communicate with the first processor, the second processor operating the pumping mechanism according to one or more operating parameters received from the first processor when the modular pumping unit is docked to the primary control unit; and

a second power source removably coupled to the modular pumping unit when the modular pumping unit is undocked.

2. The pump of claim 1, wherein the pumping mechanism is configured to manipulate a portion of a fluid delivery set to pump a fluid.

3. The pump of claim 2, wherein the second processor of each modular pumping unit is configured to operate according to the one or more operating parameters to pump the fluid after being undocked from the primary control unit.

4. The pump of claim 1, wherein the second power source comprises a communication module configured to communicate wirelessly with the first processor.

5. The pump of claim 1, wherein the second processor of each modular pumping unit is configured to modify the operation of the modular pumping unit in response to actuation of at least one input element on the modular pumping unit.

6. The pump of claim 1, wherein the first power source is coupled to the second processor, the first power source configured to provide power to the second processor when the modular pumping unit is not docked to the primary control unit.

7. The pump of claim 1, wherein the second power source is configured to provide power to the second processor and the pumping mechanism when the modular pumping unit is not docked to the primary control unit.

8. The pump of claim 1, wherein the modular pumping unit further comprises a docking connector coupled to the second processor and pumping mechanism, the docking connector configured to couple to the primary control unit when the modular pumping unit is docked to the primary control unit, and wherein the second power source is configured to removably couple to the docking connector.

9. A method of delivering fluid, the method comprising the steps of:

coupling a plurality of modular pumping units to a primary control unit comprising a plurality of docking stations configured to accept one or more modular pumping units such that each modular pumping unit may be docked and undocked in a docking station without docking or undocking another of the modular pumping units;

configuring one or more operating parameters into a first processor of the primary control unit;

transferring the one or more operating parameters from the first processor to a second processor of each modular pumping unit coupled to the primary control unit;

undocking a modular pumping unit of the one or more modular pumping units from the primary control unit;

coupling a first power source to the modular pumping unit;

coupling the modular pumping unit to a source of fluid;

operating a pumping mechanism of the modular pumping unit, according to the transferred operating parameters, to pump a fluid from the source of fluid.

10. The method of claim 9, further comprising coupling a cassette of a delivery set to the pumping mechanism.

11. The method of claim 10, wherein coupling the modular pumping unit to a source of fluid comprises coupling the delivery set to the source of fluid, such that operating the pumping mechanism transfers fluid from the source.

12. The method of claim 9, further comprising modifying the operation of the modular pumping unit by the second processor in response to actuation of at least one input element on the modular pumping unit.

13. The method of claim 9, further comprising modifying the operation of the pumping mechanism in response to actuation of at least one input element on the modular pumping unit.

14. The method of claim 9, further comprising the first power source providing power to at least the first processor when the modular pumping unit is undocked from the primary control unit.

15. The method of claim 14, further comprising the first power source providing power to the pumping mechanism when the modular pumping unit is undocked from the primary control unit.

16. The method of claim 9, further comprising coupling a second power source to the modular pumping unit when the modular pumping unit is undocked from the primary control unit, the second power source providing power to at least the pumping mechanism when the modular pumping unit is undocked from the primary control unit.

17. The method of claim 16, further comprising the second power source charging the first power source when the modular pumping unit is undocked from the primary control unit.

18. The method of claim 16, further comprising communicating wirelessly between the first processor and the second processor using a communication module of the second power source.

19. The method of claim 18, further comprising communicating the one or more operating parameters wirelessly between the first processor and the second processor.
