Abstract

Some embodiments of an infusion pump system includes a controller device that is configured to removably attach to a pump device in a manner that provides a secure fitting, an overall compact size, and a reliable electrical connection. In particular embodiments, the controller device can be secured to the pump device in a generally side-by-side arrangement. The compact size can enhance the discreteness and portability of the infusion pump system.

Claims

1. A portable infusion pump system to dispense medicine to a user, comprising:

a disposable and non-reusable pump device including;

a pump housing that defines a space that extending along a longitudinal axis to a receive a pre-filled medicine cartridge, and a drive system to dispense medicine from the pump device when the medicine cartridge is received in the space;

a reusable controller device removably attachable to the disposable and non-reusable pump device in a side-by-side arrangement, wherein a first electrical connector of the pump device mates with a second electrical connector of the controller device when the controller device removably attaches to the pump device in the side-by-side arrangement; and

a release member that is movably mounted to one of the pump device and the controller device, the release member being adjustable by a user from a locking position in which the controller device and the pump device are retained in the side-by-side arrangement to a second position in which the controller device and the pump device are detachable from one another.

2. The pump system of claim 1, wherein the release member comprises a latch that is biased toward the locking position to engage the pump device.

3. The pump system of claim 2, wherein the latch is arranged to engage a lateral side of the pump device when in the locked position.

4. The pump system of claim 3, wherein the latch is adjusted to the second position when shifted away from the lateral side of the pump device.

5. The pump system of claim 3, wherein the latch is arranged to engage a segmented guide rail along the lateral side of the pump device when in the locked position.

6. The pump system of claim 1, wherein the release member is in the locking position, the controller device and the pump device are retained in the side-by-side arrangement so as to maintain an electrical connection between the first electrical connector of the pump device mates and the second electrical connector of the controller device.

7. The pump system of claim 6, wherein the first electrical connector is biased to automatically separate from the second electrical connector in response to the release member being adjusted to the second position.

8. The pump system of claim 1, wherein the pump housing encloses at least a portion of the drive system of the pump device, and the controller device comprises a controller housing to enclose at least a portion of control circuitry that activates the drive system via electrical signals communication via an electrical connection via the first electrical connector and the second electrical connector of the controller device.

9. The pump system of claim 8, wherein the pump housing is not surround by the controller housing when the pump device is removably attached with the controller device in the side-by-side arrangement.

10. A portable infusion pump system to dispense medicine to a user, comprising:

a disposable and non-reusable pump device including at least a portion of a drive system to dispense medicine from a prefilled medicine cartridge when the medicine cartridge is slidably inserted into the pump device;

a reusable controller device removably attachable to the disposable and non-reusable pump device in a side-by-side arrangement, the controller device having a user interface display and being in electrical communication with an electrically powered component housed inside the pump device when the controller device is removably attached to the pump device; and

a release member that is movably mounted to one of the pump device and the controller device, the release member being adjustable from a locking position in which the controller device and the pump device are retained in a side-by-side arrangement to a second position in which the controller device and the pump device are detachable from one another.

11. The pump system of claim 10, wherein the release member comprises a latch that is biased toward the locking position to engage the pump device.

12. The pump system of claim 11, wherein the latch is arranged to engage a lateral side of the pump device when in the locked position.

13. The pump system of claim 12, wherein the latch is adjusted to the second position when shifted away from the lateral side of the pump device.

14. The pump system of claim 12 wherein the latch is arranged to engage a segmented guide rail along the lateral side of the pump device when in the locked position.

15. The pump system of claim 10, wherein a first electrical connector of the pump device mates with a second electrical connector of the controller device when the controller device and the pump device are removably attached in the side-by-side arrangement.

16. The pump system of claim 15, wherein the first electrical connector is biased to automatically separate from the second electrical connector in response to adjustment of the release member to the second position.

17. The pump system of claim 10, wherein the pump device comprises a pump housing to enclose at least a portion of the drive system, and the controller device comprises a controller housing to enclose at least a portion of control circuitry.

18. The pump system of claim 17, wherein the pump housing is not surround by the controller housing when the pump device is retained with the controller device in the side-by-side arrangement.
