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 system comprising:

a control unit comprising a plurality of docking stations, a monitoring application, and a control unit processor to communicate one or more operating parameters to a modular pumping unit that docks and undocks in a docking station of the control unit, each docking station configured to provide power to a docked modular pumping unit when the docked modular pumping unit is docked at the docking station;

a first modular pumping unit comprising a pumping mechanism, a wireless communication module, a docking connector configured to dock the first modular pumping unit at a respective docking station, and a pumping unit processor,

wherein the pumping unit processor is configured to communicate with the control unit processor through the docking connector to receive a first operating parameter and operate the pumping mechanism according to the first operating parameter when the first modular pumping unit is docked at the respective docking station and, when the first modular pumping unit becomes undocked from the respective docking station, continue to operate the pumping mechanism according to the first operating parameter, and

wherein the wireless communication module is configured to, while the first modular pumping unit becomes undocked from the respective docking station, communicate with the monitoring application to receive a second operating parameter, such that the pumping mechanism changes operation from the first operating parameter to the second operating parameter.

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

3. The pump system of claim 1, wherein the first modular pumping unit may be docked and undocked in a docking station without docking or undocking another second modular pumping unit.

4. The pump system of claim 1, wherein the first modular pumping unit comprises a first power source, coupled to the pumping unit processor, to provide power to the pumping unit processor when the first modular pumping unit is not docked to the control unit.

5. The pump system of claim 1, further comprising a second power source removably coupled to the first modular pumping unit when the first modular pumping unit is not docked to the control unit.

6. The pump system of claim 5, wherein the second power source is configured to provide power to the pumping unit processor and the pumping mechanism when the first modular pumping unit is not docked to the control unit.

7. The pump system of claim 5, wherein the first modular pumping unit further comprises a docking connector coupled to the pumping unit processor and the pumping mechanism, the docking connector configured to couple to the control unit when the first modular pumping unit is docked to the control unit, and wherein the second power source is configured to removably couple to the docking connector.

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

9. The pump system of claim 1, wherein the wireless communication module is configured to communicate operational data of the first modular pumping unit with the monitoring application.

10. A pump system comprising:

a control unit having a plurality of docking stations that accept one or more modular pumping units, a first monitoring application, and a control unit processor to communicate one or more operating parameters to a modular pumping unit docked in one of the plurality of docking stations, each docking station configured to provide power to a docked modular pumping unit when the docked modular pumping unit is docked at the docking station; and

a first modular pumping unit comprising;

a power source;

a pumping mechanism;

a docking connector configured to dock with a respective docking station and to receive power from the control unit via the respective docking station; and

a pumping unit processor configured to communicate with the control unit processor through the docking connector to receive a first operating parameter and operate the pumping mechanism according to the first operating parameter when the modular pumping unit is docked at the respective docking station and, when the first modular pumping unit becomes undocked from the respective docking station, continue to operate the pumping mechanism according to the first operating parameter; and

a wireless communication module configured to, while the first modular pumping unit becomes undocked from the respective docking station, communicate with the first monitoring application to receive a second operating parameter, thereby changing operation of the pumping mechanism.

11. The pump system of claim 10, further comprising a server, the server comprising a second monitoring application, and a portable device comprising a third monitoring application, the second and third monitoring applications configured to communicate with the wireless communication module.

12. The pump system of claim 11, wherein the wireless communication module is configured to communicate operational data of the first modular pumping unit with any of the first, second, and third monitoring application.

13. The pump system of claim 10, wherein the pumping mechanism is configured to manipulate a portion of a fluid delivery set, coupled to the first modular pumping unit, to pump a fluid.

14. The pump system of claim 10, wherein the first modular pumping unit may be docked and undocked in a docking station without docking or undocking another second modular pumping unit.

15. The pump system of claim 10, comprising an first power source, coupled to the pumping unit processor, to provide power to the pumping unit processor when the first modular pumping unit is not docked to the control unit.

16. The pump system of claim 10, comprising a second power source removably coupled to the first modular pumping unit when the first modular pumping unit is not docked to the control unit.
