Abstract

A wearable infusion device comprises a reservoir that holds a liquid medicament, an outlet port that delivers the liquid medicament to a patient, a pump that displaces a volume of the liquid medicament to the outlet port when actuated, and a control that actuates the pump. The control is arranged to provide a perceptible indication that the pump has been actuated.

Claims

1-10. -10. (canceled)

11. A wearable infusion device comprising:

a reservoir that holds a liquid medicament;

an outlet port that delivers the liquid medicament to a patient;

a pump that displaces a volume of the liquid medicament to the outlet port when actuated; and

a control that actuates the pump, the control comprising an actuator arranged to provide a perceptible indication that the pump has been actuated.

12. The device of claim 11, wherein the perceptible indication is a tactile indication.

13. The device of claim 12, wherein the control comprises a snap action actuator and the tactile indication is that of snap action.

14. The device of claim 11, wherein the perceptible indication is an audible indication.

15. The device of claim 14, wherein the audible indication is a sharp sound.

16. The device of claim 14, wherein the control comprises a snap action actuator and wherein the audible indication is a snap sound.

17. The device of claim 11, wherein the control includes a pair of actuator buttons arranged to require concurrent operation for pump actuation.

18. The device of claim 17, wherein only one of the actuator buttons causes the actuator to provide a perceptible indication that the pump has been actuated.

19. The device of claim 18, wherein operation of the other one of the actuator buttons enables actuation of the pump.

20. The device of claim 17, wherein the perceptible indication is a tactile indication.

21. The device of claim 17, wherein the perceptible indication is an audible indication.

22. A wearable infusion device comprising:

a reservoir that holds a liquid medicament;

an outlet port that delivers the liquid medicament to a patient;

a pump that displaces a volume of the liquid medicament to the outlet port when actuated; and

a control that actuates the pump, the control comprising a pair of actuator buttons arranged to require concurrent operation for pump actuation and providing a combined perceptible tactile and audible indication that the pump has been actuated.
