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 including a pump housing 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 non-rechargeable battery positioned within the pump housing, the pump device including a memory device positioned within the pump housing storing data indicative of a charge level of the non-rechargeable battery positioned within the pump housing; and

a controller device removably attachable to the pump housing of the pump device, the controller device housing control circuitry and at least one memory device that is different from the memory device positioned within the pump housing, wherein when the controller device is removably attached to the pump housing of the pump device, the controller device activates the drive system to dispense the medicine source and receives from the memory device positioned within the pump housing the data indicative of the charge level of the non-rechargeable battery, wherein the memory device positioned within the pump housing stores the data indicative of the charge level of the non-rechargeable battery positioned within the pump housing when the pump device is detached from the controller, and wherein the controller device is configured to query the memory device positioned within the pump housing and store the data indicative of the charge level of the non-rechargeable battery in response to attaching the pump device to the controller device.

2. The system of claim 1, wherein the controller device includes a user interface comprising a display device.

3. The system of claim 1, wherein the pump device includes at least one structure that hinders 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 data regarding the charge level of the non-rechargeable battery indicates whether the non-rechargeable battery is in a depleted or non-depleted state.

5. The system of claim 4, wherein the controller device includes a rechargeable energy source that is different from the non-rechargeable battery of the pump device.

6. The system of claim 1, wherein the controller device comprises a controller housing and 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 an electrical connection between the controller device and the pump device.

7. The system of claim 6, wherein the control circuitry is 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.

8. The system of claim 1, wherein:

the pump device includes 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; and

the controller device includes a controller housing, a user interface display and user-selectable inputs for programming the controller device, and an energy storage source positioned within the controller housing.

9. The system of claim 8, wherein the pump device includes at least one structure that hinders reuse of the pump device after the medicine source is exhausted such that the pump device is non-reusable and disposable.

10. The system of claim 8, 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 an electrical connection between the controller device and the pump device.

11. The system of claim 10, wherein the control circuitry is 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.

12. The system of claim 8, wherein the control circuitry is in electrical communication with the memory device positioned in the pump housing so as to access the data of the memory device when the controller device is removably attached to the pump device.

13. The system of claim 12, wherein 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.

14. The system of claim 13, 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.

15. The system of claim 14, when the data stored in the memory device regarding the charge level of the battery indicates that the 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.

16. A wearable infusion pump system comprising:

a pump device including a pump housing 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 battery positioned within the pump housing, the pump device including a memory device positioned within the pump housing storing data indicative of a charge level of the battery positioned within the pump housing; and

a controller device removably attachable to the pump housing of the pump device, wherein when the controller device is removably attached to the pump housing of the pump device, the controller device activates the drive system to dispense the medicine source and receives from the memory device positioned within the pump housing the data indicative of the charge level of the battery;

wherein the battery is a non-rechargeable battery;

wherein the data regarding the charge level of the battery indicates whether the battery is in a depleted or non-depleted state;

wherein the controller device includes a rechargeable energy source that is different from the battery of the pump device; and

when the data stored in the memory device housed in the pump device regarding the charge level of the battery indicates that the battery is in the depleted state, the controller device ceases recharging of the rechargeable energy source housed within the controller device from the battery housed in the pump housing of the pump device.

17. The system of claim 16, wherein the controller device includes a user interface comprising a display device.

18. The system of claim 16, wherein the pump device includes at least one structure that hinders reuse of the pump device after the medicine source is exhausted such that the pump device is non-reusable and disposable.

19. The system of claim 16, wherein:

the pump device includes 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; and
