Abstract

Some embodiments of an infusion pump system may include an illumination instrument that provides the user with an opportunity to illuminate and inspect a targeted location. The illumination instrument can be useful in situations where the ambient lighting is insufficient for the user'"'"'s inspection needs (e.g., during the night, during presentation or movie in which the lighting is low, or the like). In some embodiments, illumination instrument can be employed to visually inspect one or more components of the pump system, the infusion set, or a combination thereof.

Claims

1. A portable and wearable infusion pump system comprising:

a pump device including;

a pump housing including an interior wall that at least partially defines a space to slidably receive a pre-filled medicine cartridge, and a drive system to dispense a medicine from the pre-filled medicine cartridge through an infusion set cannula adapted to penetrate a user'"'"'s skin;

an infusion pump controller including control circuitry that transmits control signals to the drive system of the pump device, and a user interface comprising a display device; and

an illumination instrument electrically connected to the control circuitry of the infusion pump controller such that the control circuitry of the infusion pump controller automatically activates the illumination instrument to emit a light beam in response to an alarm condition, wherein the illumination instrument is different from the display device of the user interface of the infusion pump controller.

2. The pump system of claim 1, wherein the illumination instrument is oriented to direct the light beam in a first direction while the display device faces a second direction that is different from the first direction.

3. The pump system of claim 1, wherein the illumination instrument is exteriorly exposed on a first face of the infusion pump controller and the display device is exteriorly exposed on a second face of the infusion pump controller that is different from the first face.

4. The pump system of claim 1, wherein the light beam emitted in response to the alarm condition has an illumination intensity that is sufficient to illuminate a circular area having a diameter of at least 10 inches.

5. The pump system of claim 1, wherein the illumination instrument emits an inspection light in response to actuating one or more buttons of the user infusion pump controller.

6. The pump system of claim 5, wherein the inspection light from the illumination instrument illuminates one or more components of the pump device.

7. The pump system of claim 5, wherein the inspection light from the illumination instrument illuminates one or more components of an infusion set.

8. The pump system of claim 1, wherein the infusion pump controller is a reusable device that is removably attachable to the pump device.

9. The pump system of claim 1, wherein the illumination instrument is housed in a controller housing of the infusion pump controller that is removably attachable to the pump housing of the pump component.

10. The pump system of claim 1, wherein the control circuitry of the infusion pump controller automatically deactivates the illumination instrument after a predetermined period of time.

11. The pump system of claim 1, wherein the control circuitry of the infusion pump controller automatically activates the light source of the illumination instrument in response to initiation of a pump priming operation.

12. A method of using a wearable infusion pump system, the method comprising:

receiving a pre-filled medicine cartridge into the wearable infusion pump system so that the pre-filled cartridge slidably engages an interior wall of a cavity of the wearable infusion pump system defining a space to receive the medicine cartridge;

activating a pump drive system of the wearable infusion pump system to dispense a portion of medicine from the pre-filled medicine cartridge; and

in response to detecting an alarm condition of the wearable infusion pump system, activating an illumination instrument electrically connected to control circuitry of the wearable infusion pump system to emit a light beam from the illumination instrument, wherein the illumination instrument is exteriorly exposed on a first face of the wearable infusion pump system and a user interface display of the wearable infusion pump system is exteriorly exposed on a second face of the wearable infusion pump system that is different from the first face.

13. The method of claim 12, further comprising directing the light from the illumination instrument in a first direction while directing a display device of a user interface in a second direction which is different from the first direction.

14. The method of claim 12, wherein the light beam emitted in response to the alarm condition has an illumination intensity that is sufficient to illuminate a circular area having a diameter of at least 10 inches.

15. The method of claim 12, wherein the illumination instrument is housed in a reusable controller device having a controller housing that is removably attachable to a pump housing of the pump component.

16. The method of claim 14, wherein the reusable controller device comprises control circuitry that automatically deactivates the illumination instrument after a predetermined period of time.

17. The method of claim 12, wherein the reusable controller device automatically activates the light source of the illumination instrument in response to initiation of a pump priming operation.

18. The method of claim 12, wherein the illumination instrument comprises an LED device positioned adjacent to a light guide, wherein the light guide extends to an external housing component of the wearable infusion pump system so that the light exits the light guide and illuminates the targeted site.

19. The method of claim 12, further comprising directing the light beam from the illumination instrument toward the targeted site on a pump component that is configured to dispense medicine in response to control signals from control circuitry of the wearable infusion pump system, wherein the illumination instrument housed in an infusion pump controller component is movable relative to the pump component while directing the light from the illumination instrument toward the targeted site.

20. The method of claim 12, further comprising directing the light beam from the illumination instrument toward an infusion site on a user'"'"'s skin.
