The present disclosure relates to a drug delivery device (1) comprising: - a case (2) adapted to retain a medicament container (3), - a plunger (10) disposed within the case (2) and slidable from a proximal position (P1) into a distal position (P2) for delivering a medicament (M) from the medicament container (3), - at least one feedback mechanism (13) that is in operative connection with the plunger (10), the feedback mechanism (13) comprising a collar (14), a needle shroud (7), a control spring (8) biasing the needle shroud (7) in a distal direction (D) relative to the collar (14), the collar (14) operatively coupling tothe case (2) in an axial direction and prevented from axially decoupling from the case (2) by the plunger (10) when in the proximal position (P1), wherein the plunger (10), during movement from the proximal position (P1) towards the distal position (P2), is adapted to allow axial decoupling of the collar (14) from the case (2) driven by the control spring (8) until the collar’s (14) movement is halted to create an audible and/or tactile feedback.本公開內容涉及一種藥物輸送裝置(1)，包括：- 外殼(2)，適於保持藥劑容器(3)，- 柱塞(10)，設在外殼(2)內且可從近側位置(P1)滑入遠側位置(P2)以從藥劑容器(3)輸送藥劑(M)，- 至少一個反饋機構(13)，與柱塞(10)可操作地連接，反饋機構(13)包括套管(14)、針護罩(7)、使針護罩(7)相對於套管(14)朝向遠側方向(D)偏壓的控制彈簧(8)，套管(14)在軸向方向上可操作地與外殼(2)聯結且當柱塞(10)處於近側位置(P1)時被柱塞(10)阻止軸向脫離外殼(2)，其中，柱塞(10)在從近側位置(P1)朝向遠側位置(P2)移動的過程中適於允許套管(14)被控制彈簧(8)驅動而軸向脫離外殼(2)，直至套管(14)的移動停止以生成聽覺及/或觸覺的反饋。
