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. A lock-out disables the device when a predefined amount of medicament has been delivered to the outlet.

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

a control that actuates the pump; and

a lock-out that disables the device when a predefined amount of medicament has been delivered to the outlet.

2. The device of claim 1, wherein the lock-out disables the control to disable the device when a predefined amount of medicament has been delivered to the outlet.

3. The device of claim 2, wherein the lock-out is a last dose lock-out.

4. The device of claim 1, wherein the lock-out disables the control when the reservoir is at a given level.

5. The device of claim 4, wherein the given level is empty.

6. The device of claim 1, further comprising a fill port communicating with the reservoir to permit the reservoir to be filled with the liquid medicament and wherein the lock-out blocks the fill port to disable the device when a predefined amount of medicament has been delivered to the outlet.

7. The device of claim 6, wherein the lock-out is a last dose lock-out.

8. The device of claim 6, wherein the lock-out is responsive to the reservoir being at a given level to block the fill port.

9. The device of claim 8, wherein the given level is empty.

10. The device of claim 6, wherein the lock-out disables the control and blocks the fill port to disable the device when a predefined amount of medicament has been delivered to the outlet.

11. The device of claim 10, wherein the lock-out is a last dose lock-out.

12. The device of claim 6, wherein the lock-out is responsive to the reservoir being at a given level to disable the control and block the fill port.

13. The device of claim 12, wherein the given level is empty.

14. 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;

a control that actuates the pump; and

a lock-out that disables the control to disable the device when the medicament level in the reservoir is at a given level.

15. 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;

a control that actuates the pump;

a fill port communicating with the reservoir to permit the reservoir to be filled with the liquid medicament; and

a lock-out that blocks the fill port to disable the device when the medicament level in the reservoir is at a given level.

16. 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;

a control that actuates the pump;

a fill port communicating with the reservoir to permit the reservoir to be filled with the liquid medicament; and

a lock-out that blocks the fill port and disables the control to disable the device when the medicament level in the reservoir is at a given level.
