The communication device includes at least one rotation detection arrangement, the at least one rotation detection arrangement being configured to detect a rotation of at least one physical part of the medicament delivery device. The communication device also includes at least one determination unit configured to determine information related to a medicament delivery performed by the medicament delivery device. The communication device further includes at least one activation unit configured to activate the at least one determination unit based on the detected rotation. Also, the communication device includes at least one transmission unit configured to provide a wireless transmission of the information to an external receiving device. ## Claims ### Claim 1 A communication device arranged for transmitting information from a medicament delivery device comprising: a switch projecting proximally and configured to detect a rotation of at least one physical part of said medicament delivery device; a printed circuit board configured to determine information related to a medicament delivery performed by said medicament delivery device; a non-rotating wall positioned within the communication device or within a housing of the medicament delivery device and projecting distally so that the switch will engage the wall to activate the printed circuit board based on said detected rotation; and a transmitter that provides a wireless transmission of said information to an external receiving device, wherein the switch is rotated by the rotation relative to the wall such that a portion of the switch is pressed against the wall activating the printed circuit board. ### Claim 2 (depends on 1) The communication device as claimed in claim 1, wherein the switch comprises a mechanical switch configured to be compressed by said rotation. ### Claim 3 (depends on 1) The communication device as claimed in claim 1, wherein said printed circuit board is configured to determine said information based on at least one revolution of said at least one rotating physical part. ### Claim 4 (depends on 1) The communication device as claimed in claim 1, wherein said printed circuit board is configured to determine said information based on preconfigured data related to said medicament delivery, said data including one or more in the group of: an identification number for said medicament delivery device; an identification number for a medicament delivered by said medicament delivery device; an identification number for a patient using the medicament delivery device; and an elapsed time since a delivery of a medicament occurred. ### Claim 5 (depends on 1) The communication device as claimed in claim 1, wherein said printed circuit board is configured to determine said information based on measured data related to said medicament delivery, said data including one or more in the group of: an identification number for said medicament delivery device; an identification number for a medicament delivered by said medicament delivery device; an identification number for a patient using the medicament delivery device; and an elapsed time since a delivery of a medicament occurred. ### Claim 6 (depends on 1) The communication device as claimed in claim 1, wherein said communication device further includes at least one indication unit configured to provide at least one indication of that said medicament delivery is performed. ### Claim 7 (depends on 1) The communication device as claimed in claim 1, wherein said communication device further comprises at least one indication unit including one or more in the group of: at least one light source configured to emit light as said at least one indication; at least one light guide configured to guide light being emitted by at least one light source as said at least one indication; at least one mechanical audible indication source configured to be compressed and released by said rotation, thereby emitting the audible indication; and at least one mechanical tactile indication source configured to be compressed and released by said rotation, thereby providing the tactile indication. ### Claim 8 (depends on 1) The communication device as claimed in claim 1, wherein said communication device is included within a housing of said medicament delivery device. ### Claim 9 (depends on 1) The communication device as claimed in claim 1, wherein said communication device is included in an external unit, said external unit being releasably attachable to said medicament delivery device. ### Claim 10 (depends on 3) The communication device as claimed in claim 3, wherein said at least one revolution is measured by said at least one rotation detection arrangement. ### Claim 11 (depends on 6) The communication device as claimed in claim 6, wherein said at least one indication is provided during said delivery and also during a predetermined time period after said delivery has ended.
