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 delivers a volume of the liquid medicament from the reservoir to the outlet when actuated, and a tactile indicator representing the volume of the liquid medicament delivered to the outlet with each actuation of the pump.

Claims

1. 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 delivers a volume of the liquid medicament from the reservoir to the outlet when actuated; and

a tactile indicator representing the volume of the liquid medicament delivered to the outlet with each actuation of the pump.

2. The device of claim 1, wherein the tactile indicator is configured to represent the volume in dosage units.

3. The device of claim 1, wherein the tactile feature comprises at least one relieved feature.

4. The device of claim 1, wherein the tactile feature comprises at least one raised feature.

5. The device of claim 4, wherein the at least one raised feature comprises a bump.

6. The device of claim 1, wherein the tactile indicator comprises at least one discrete tactile feature and wherein each discrete tactile feature corresponds to one dosage unit.

7. The device of claim 1, further comprising an actuator button that, when pushed, actuates the pump, and wherein the tactile indicator is carried on the actuator button.

8. The device of claim 7, wherein the tactile indicator is configured to represent the volume in dosage units.

9. The device of claim 7, wherein the tactile indicator comprises at least one discrete tactile feature and wherein each discrete tactile feature corresponds to one dosage unit.

10. The device of claim 7, wherein the tactile indicator comprises at least one relieved feature.

11. The device of claim 7, wherein each the tactile indicator comprises at least one raised feature.

12. The device of claim 11, wherein the at least one raised feature comprises a bump.

13. The device of claim 1, further comprising a pair of actuator buttons associated with the pump which, when concurrently pressed, cause the pump to be actuated, and wherein the tactile indicator is carried on at least one of the actuator buttons.

14. The device of claim 13, wherein the tactile indicator is configured to represent the volume in dosage units.

15. The device of claim 13, wherein the tactile indicator comprises at least one discrete tactile feature and wherein each discrete tactile feature corresponds to one dosage unit.

16. The device of claim 13, wherein the tactile indicator comprises at least one relieved feature.

17. The device of claim 13, wherein the tactile indicator comprises at least one raised feature.

18. The device of claim 17, wherein the at least one raised feature comprises a bump.

19. 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 delivers a volume of the liquid medicament from the reservoir to the outlet when actuated;

a tactile indicator representing the volume of the liquid medicament delivered to the outlet with each actuation of the pump; and

a pair of actuator buttons associated with the pump which, when concurrently pressed, cause the pump to be actuated,

wherein the tactile indicator is carried on one of the actuator buttons.

20. The device of claim 19, wherein one of the actuator buttons is directly coupled to the pump, and wherein the tactile indicator is carried on the actuator button directly coupled to the pump.

21. The device of claim 20, wherein the pump is a piston pump, wherein the piston pump includes an extension, and wherein the tactile indicator is carried on the extension.
