Abstract

A pump system can include a pump device and a controller device removably attachable to the pump device. The controller device can be reusable, and one or more pump devices can be disconnected and reconnected to the controller device. As such, some pump usage data can be conveniently stored in the pump device itself. In such circumstances, the controller device can receive data related to the pump'"'"'s history or other usage when the pump device is attached to the controller.

Claims

1. A wearable infusion pump system comprising:

a pump device defining a space to receive a medicine source, the pump device including a drive system to dispense medicine from the pump device when the medicine source is received in the space, the pump device including a memory device storing an energy requirement profile to perform a medicine dispensing operation, the energy requirement profile being defined by the drive system;

a controller device removably attachable to the pump device, the controller device including an energy storage source, wherein when the controller device is removably attached to the pump device the controller device receives the energy requirement profile from the memory device and initiates a medicine dispensing operation by supplying a pattern of voltage pulses from the energy storage source to the drive system, the pattern of voltage pulses being correlated to the energy requirement profile of the drive system.

2. The system of claim 1, wherein the controller device detects a time period for completing a medicine dispensing operation, adjusts the energy requirement profile for the pump device based on the detected time period, and records the adjusted energy requirement profile on the memory device.

3. The system of claim 1, wherein the energy requirement profile is a torque profile.

4. The system of claim 1, wherein the pump device is non-reusable and disposable.

5. The system of claim 1, wherein the memory device of housed in the pump device stores an event log of pump system operations.

6. The system of claim 5, wherein the event log includes time and date information for medicine dispensing operations.

7. The system of claim 6, wherein the controller device includes a user interface and the event log includes time and date information for user input.

8. The system of claim 6, wherein the event log includes time and date information for sensor inputs.

9. The system of claim 1, wherein the memory device of housed in the pump device stores data indicative of a charge level of the battery housed in the pump device, the battery being a non-rechargeable battery.

10. The system of claim 9, wherein the controller device includes a rechargeable energy source.

11. A wearable infusion pump system comprising:

a pump device including a pump housing structure that defines a space to receive a medicine source and a cap device attachable to the pump housing structure such that a penetration member of the cap device extends into an interior of the space to penetrate a septum with the medicine source is received in the space, the pump device including a drive system to dispense medicine from the pump device when the medicine source is received in the space, the pump device including a memory device storing an energy requirement profile to perform a medicine dispensing operation, the energy requirement profile being defined by the drive system;

a controller device removably attachable to the pump device and including a user interface display and buttons for programming the controller device, the controller device including an energy storage source, wherein when the controller device is removably attached to the pump device the controller device receives the energy requirement profile from the memory device housed in the pump housing structure and initiates a medicine dispensing operation by supplying a pattern of voltage pulses from the energy storage source to the drive system, the pattern of voltage pulses being correlated to the energy requirement profile of the drive system housed in the pump housing structure.

12. The system of claim 11, wherein the controller device detects a time period for completing a medicine dispensing operation, adjusts the energy requirement profile for the pump device based on the detected time period, and records the adjusted energy requirement profile on the memory device.

13. The system of claim 11, wherein the energy requirement profile is a torque profile.

14. The system of claim 11, wherein the pump device is non-reusable and disposable.

15. The system of claim 11, wherein the memory device of housed in the pump housing structure stores an event log of pump system operations.

16. The system of claim 15, wherein the event log includes time and date information for medicine dispensing operations.

17. The system of claim 16, wherein the controller device includes a user interface and the event log includes time and date information for user input.

18. The system of claim 16, wherein the event log includes time and date information for sensor inputs.

19. The system of claim 11, wherein the memory device of housed in the pump housing structure stores data indicative of a charge level of the battery housed in the pump device, the battery being a non-rechargeable battery.

20. The system of claim 19, wherein the controller device includes a rechargeable energy source.
