Abstract

A supplemental device for attachment to an injection device, the supplemental device is presented having a processor arrangement; and a quantity determiner for determining a quantity of medicament that has been delivered, wherein the quantity determiner has a sensor arranged to detect movement of a drive screw of the injection device during medicament delivery.

Claims

1-14. -14. (canceled)

15. A supplemental device for attachment to an injection device, the supplemental device comprising:

a processor arrangement; and

a quantity determiner for determining a quantity of medicament that has been delivered, wherein the quantity determiner comprises a sensor arranged to detect movement of a drive screw of the injection device during medicament delivery.

16. The supplemental device according to claim 15, the supplemental device further comprising a display, wherein the processor arrangement is configured to control the display to indicate the quantity of medicament that has been delivered.

17. The supplemental device according to claim 15, wherein the quantity determiner comprises a camera and wherein the processor arrangement is configured to interpret signals provided by the camera to determine the quantity of medicament that has been delivered.

18. The supplemental device according to claim 15, wherein the quantity determiner comprises two or more cameras and wherein the processor arrangement is configured to interpret signals provided by the cameras to determine the quantity of medicament that has been delivered.

19. The supplemental device according to claim 15, wherein the quantity determiner comprises a light source and a photosensor and wherein the processor arrangement is configured to interpret signals provided by the photosensor to determine the quantity of medicament that has been delivered.

20. The supplemental device according to claim 15, wherein the quantity determiner comprises an inductive sensor and wherein the processor arrangement is configured to interpret signals provided by the inductive sensor to determine the quantity of medicament that has been delivered.

21. The supplemental device according to claim 15, wherein the quantity determiner is configured to detect both rotation and linear advancement of the drive screw.

22. The supplemental device according to claim 15, further comprising:

a dose dialled detector operable to detect a dose of medicament dialled into an attached injection device; and

a dose delivery determiner for determining that a dose of medicament has been delivered.

23. The system comprising a supplemental device as claim 17 and an injection device.

24. The system according to claim 23, wherein the drive screw of the injection device includes helical markings on a surface thereof.
