Abstract

An injection device to deliver at least two medicaments is disclosed where a first medicament is delivered in settable doses with a first medicament dose delivery mechanism and a second medicament is delivered from micro-reservoirs upon activation of a second medicament delivery system, whereby activation of the second medicament delivery system locks out the first medicament dose delivery mechanism.

Claims

1-11. -11. (canceled)

12. A drug delivery device, comprising,

a cartridge of a first medicament;

a first medicament dose delivery mechanism configured for user settable and administration of multiple doses of the first medicament through a dispense interface;

a plurality of micro-reservoirs of a second medicament; and

a second medicament delivery system configured to deliver a preset dose of the second medicament through the dispense interface or a second dispense interface.

13. The drug delivery device of claim 12 where the second medicament delivery system comprises a microchip coupled to a microprocessor for controlling delivery of the preset dose.

14. The drug delivery device of claim 12 where activation of the second medicament delivery system locks out the first dose delivery mechanism preventing further dose setting and administration of the first medicament.

15. The drug delivery device of claim 12 where the dispense interface is a needle cannula.

16. The drug delivery device of claim 12 further comprising an electronic circuit system coupled to the second medicament delivery system configured to output a plurality of electronic outputs instructing a user of the drug delivery device on how to administer a dose of the second medicament.

17. The drug delivery device of claim 12 further comprising an electronic circuit system coupled to the second medicament delivery system configured to transmit to a receiver a signal indicating activation of the second medicament delivery system.

18. The drug delivery device of claim 12 where the drug delivery device is configured as a pen-type injection device.

19. The drug delivery device of claim 12 where the second medicament delivery system comprises an electromechanical microchip configured to formulate the second medicament through a reconstitution step and subsequently deliver a non-user settable dose of the second medicament through a needle cannula.

20. The drug delivery device of claim 12 where the second medicament delivery system is programmable through a wireless connection.

21. The drug delivery device of claim 12 where the first medicament is insulin and the second medicament is glucagon solution.

22. The drug delivery device of claim 20 where the glucagon solution is formulated by the second medicament delivery system through reconstitution of lyophilized glucagon and a liquid excipient.
