A communication device arranged for transmitting information from a medicament delivery device is presented. The communication device includes at least one translation detection arrangement, configured to detect a translation of at least one physical part of the medicament delivery device by utilization of a resilience and an electrical conductivity for at least one spring of the medicament delivery device. The communication device also includes at least one change of state detection unit, configured to detect at least one change of state for the medicament delivery device based on the detected translation. The communication device further includes at least one activation unit, configured to activate the at least one change of state detection unit based on the at least one detected translation. The communication device also includes at least one transmission unit configured to provide a wireless transmission of information related to the at least one change of state to an external receiving device.被配置用於傳輸來自藥物輸送裝置之資訊的通訊裝置被呈現。該通訊裝置包括至少一平移偵測裝置，被建構用於藉由用於該藥物輸送裝置的至少一彈簧之彈性及導電性的利用率，偵測該藥物輸送裝置之至少一實體部份的平移。該通訊裝置亦包括至少一狀態變化偵測單元，被建構用於基於該被偵測之平移偵測用於該藥物輸送裝置的至少一狀態變化。該通訊裝置另包括至少一啟動單元，被建構用於基於該至少一被偵測之平移而啟動該至少一狀態變化偵測單元。該通訊裝置亦包括至少一傳輸單元，被建構用於將有關該至少一狀態變化的資訊之無線傳輸提供至外部接收裝置。
