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.

First claim

What is claimed is:

1. 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 when 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 battery positioned in the pump housing, and the pump device including a memory device storing data indicative of a charge level of the battery and positioned in the pump housing; and
a controller device removably attachable to the pump device, the controller device housing an energy storage source, wherein the controller device is configured to activate the drive system in the pump housing to dispense the medicine source via an electrical connection between the controller device and the pump device while the controller is removably attached to the pump device, and wherein the controller device is configured to receive the data indicative of the charge level of the battery positioned in the pump housing via the electrical connection between the controller device and the pump device while the controller is removably attached to the pump device, wherein the controller device starts and stops recharging of the energy storage source positioned in the controller device from the battery positioned in the pump housing structure based on the data indicative of the charge level of the battery positioned in the pump housing.

2. The system of claim 1 , wherein the controller device comprises control circuitry positioned in the controller housing, the control circuitry being in electrical communication with the memory device positioned in the pump housing so as to access the data of the memory device positioned in the pump housing via the electrical connection between the controller device and the pump device while the controller is removably attached to the pump device.

3. The system of claim 1 , wherein the pump device includes at least one structure positioned to prevent reuse of the pump device after the medicine source is exhausted such that the pump device is non-reusable and disposable.

4. The system of claim 1 , wherein the controller device comprises first electrical contacts exposed along an exterior of the controller housing, wherein the pump device comprises second electrical contacts exposed along an exterior of the pump housing, and wherein when the controller device is removably attached to the pump device, the first electrical contacts and the second electrical contacts provide said electrical connection between the controller device and the pump device.

5. The system of claim 4 , wherein the controller device comprises control circuitry positioned in the controller housing, the control circuitry being in electrical communication with the memory device housed in the pump device via the electrical connection when the controller device is removably attached to the pump device.

6. The system of claim 1 , wherein the user interface of the controller device includes a display device and user-selectable inputs for programming the controller device.

7. The system of claim 1 , wherein the controller device comprises a user interface.

8. The system of claim 1 , wherein the controller device comprises at least one memory that is different from the memory device positioned within the pump housing structure.

9. The system of claim 1 , wherein the memory device positioned within the pump housing structure stores data indicative of a charge level of the non-rechargeable battery when the pump housing structure is detached from the controller device.

10. The system of claim 9 , wherein the controller device is configured to query the memory device positioned within the pump housing structure and store the data in response to attaching the pump housing structure to the controller device.

11. The system of claim 1 , wherein the battery housed in the pump housing is a non-rechargeable battery, the data regarding the charge level of the non-rechargeable battery indicates whether the non-rechargeable battery is in a depleted or non-depleted state.

12. The system of claim 11 , wherein the energy storage source of the controller device is a rechargeable energy source that is different from the non-rechargeable battery positioned in the pump housing.

13. The system of claim 12 , wherein when the data stored in the memory device regarding the charge level of the non-rechargeable battery indicates that the non-rechargeable battery is in the depleted state, the controller device ceases recharging of the rechargeable energy source positioned in the controller housing from the battery positioned in the pump housing.

14. 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 battery positioned in the pump housing, and the pump device including a memory device storing data indicative of a charge level of the battery and positioned in the pump housing, wherein the memory device positioned in the pump device stores an event log of pump system operations; and
a controller device removably attachable to the pump device and including a user interface for programming the controller device, the controller device housing an energy storage source, wherein the controller device is configured to activate the drive system in the pump housing to dispense the medicine source via an electrical connection between the controller device and the pump device while the controller is removably attached to the pump device, and wherein the controller device is configured to receive the data indicative of the charge level of the battery positioned in the pump housing via the electrical connection between the controller device and the pump device while the controller is removably attached to the pump device.

15. The system of claim 14 , wherein the event log includes time and date information for medicine dispensing operations.

16. The system of claim 14 , wherein the event log includes time and date information for sensor inputs.

17. The system of claim 14 , wherein the event log includes time and date information for medicine dispensing operations or sensor inputs.

18. The system of claim 14 , wherein the event log includes time and date information for user input actions entered via the user interface of the controller device.

19. The system of claim 18 , wherein the user interface is part of the controller device.

20. 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
