Abstract

A medication delivery device comprises an injection device having a reservoir comprising a medicament to be ejected, and a sensor arranged to detect an ejection of the medicament from the injection device, the sensor being arranged to output a signal comprising ejecting information, and a processor for collecting and storing the ejection information.

Claims

1. A medication delivery device (100) comprising an injection device (100) having a reservoir comprising a medicament to be ejected, the device further comprising:

a sensor arranged to detect an ejection of the medicament from the injection device, the sensor being arranged to output a signal comprising ejecting information, and

a processor for collecting and storing the ejection information.

2. A device according to claim 1, further comprising an communication means (162,164) arranged to transmit the ejecting information to an external data receiving device (108).

3. A device according to claim 2, wherein the external data receiving device (108) forms an integral part of a cover (108) for covering at least a needle portion (102) of the injection device (100).

4. A device according to claim 1 wherein the cover further comprises at least one of:

a display device (110,124,134) for displaying a representation of the ejecting information; and

a storage device for storing a representation of the ejecting information.

5. A device according to claim 1 wherein the ejection information comprises at least one of:

time of at least one ejected dose,

time elapsed since the last ejection,

a dose quantity of ejected medicament,

an identification of the cartridge,

an identification of the injection device, and

an identification of the type of medicament.

6. A device according to claim 1 wherein the communication means (162,164) comprises one single interface (162,164) arranged to communicate data to the external data receiving device (108) and to communicate data to a further external data receiving device (112,114).

7. A device according to claim 2 wherein the communication means (162,164) comprises two separate interfaces (162,164), one (162,164) of which is arranged to communicate data to the external data receiving device (108) of the cover (108), and another one of which is arranged to communicate data to a further external data receiving device (112,114).

8. A device according to claim 1 wherein the communication means (162,164) comprises at least one of:

an electrical conductor (162,164),

a device for wireless data transmission,

a device for optical data transmission,

a device for acoustical data transmission,

a device for capacitive data transmission, and

a device for inductive data transmission.

9. A device according to claim 1 wherein the cover (108) is attachable to the injection device (100) such that an ejection may only be performed when the cover (108) is removed from the injection device (100).

10. An injection device for a medication delivery device according to claim 1, the injection device (100) comprising:

a sensor arranged to detect an ejection of a medicament from the injection device (100);

an processor for collecting ejection information detected by the sensor;

communication means (162,164) for transmitting ejection information to said data receiving device (108) of said cover (108).

11. A cover for a medication delivery device according to claim 1, comprising an data receiving device and signal receiving means for receiving said ejecting information, the cover (108) further comprising at least one of:

a storage device for storing the ejection information and

a display device (110,124,134) for displaying the ejection information.

12. A kit comprising a medication delivery device according to claim 1 and a cradle (114) comprising means for performing at least one of:

supplying electrical power to the data receiving device of the cover (108);

transmitting data between the medication delivery device (100) and an external computer (112).
