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 comprising:

a prefilled injection device comprising

a needle mount that accepts a needle,

a reservoir having a longitudinal axis and comprising a medicament to be ejected,

a sensor arranged to detect an ejection of the medicament from the injection device and to subsequently output a signal comprising ejecting information that comprises a dose quantity of the ejected medicament,

a processor arranged to collect and store the ejection information, and

a communication structure arranged to transmit the ejecting information to an external data receiving device;

wherein the reservoir is non-exchangeable, non-refillable, and forms an integral part of the prefilled injection device,

wherein the sensor comprises a movable part adapted to rotate relative to a stationary part during ejection to determine the ejected dose,

wherein the moveable part rotates about the longitudinal axis during ejection, and

wherein the stationary part remains stationary relative to the delivery device during ejection.

2. The medication delivery device according to claim 1, further comprising a cover adapted to cover at least a needle portion of the injection device, wherein the external data receiving device forms an integral part of the cover.

3. The medication delivery device according to claim 2, wherein the cover comprises at least one of:

a display device arranged to display a representation of the ejecting information; and

a storage device arranged to store a representation of the ejecting information.

4. The medication delivery device according to claim 2, wherein the cover is attachable to the injection device such that an ejection may only be performed when the cover is removed from the injection device.

5. The medication delivery device according to claim 1, wherein the ejecting information further comprises at least one of:

time of at least one ejected dose,

time elapsed since the last ejection,

an identification of the reservoir,

an identification of the injection device, and

an identification of the type of medicament.

6. The medication delivery device according to claim 1, wherein the communication structure comprises one single interface arranged to communicate data to the external data receiving device and to communicate data to a further external data receiving device.

7. The medication delivery device according to claim 1, wherein the communication structure comprises two separate interfaces, one of which is arranged to communicate data to the external data receiving device, and another one of which is arranged to communicate data to a further external data receiving device.

8. The medication delivery device according to claim 1, wherein the communication structure comprises at least one of:

an electrical conductor,

a device arranged to transmit wireless data,

a device arranged to transmit optical data,

a device arranged to transmit acoustical data,

a device arranged to transmit capacitive data, and

a device arranged to transmit inductive data.

9. The medication delivery device according to claim 1, further comprising the external data receiving device on a cover adapted to cover the injection device.

10. A cover for a medication delivery device according to claim 1, comprising:

a data receiving device and signal receiving structure arranged to receive ejecting information,

a storage device arranged to store the ejecting information, and

a display device arranged to display the ejecting information.

11. A kit comprising a medication delivery device according to claim 1 and a cradle structure arranged to perform at least one of:

supplying electrical power to a data receiving device of a cover adapted to cover the prefilled injection device; and

transmitting data between the medication delivery device and an external computer.
