The present invention relates to a medicament delivery device comprising: a housing (10, 16) having a distal and an proximal end, said housing being adapted to receive a medicament container (18) with a delivery member (20) or with a connectable delivery member for delivery of a medicament； a drive mechanism (54) arranged to act on a plunger rod (58), which plunger rod (58) in turn is arranged to act on the medicament container (18) for providing automatic delivery of the medicament； a release mechanism (62) interactively connected to the drive mechanism (54) for releasing the drive mechanism (54) from a pre-tensioned state； a signal generating mechanism (90) for generating an audible and/or tactile and/or visual signal indicating that the medicament has been completely delivered, which signal generating mechanism (90) is operably connected to said drive mechanism such that it is arranged movable in a longitudinal direction in relation to said drive mechanism (54), that said drive mechanism (54) is arranged with a signal release mechanism (111) capable of activating said signal generating mechanism (90) at a certain longitudinal position of said drive mechanism after its release, for generating anaudible and/or tactile and/or visual signal, wherein said signal generating mechanism (90) comprises a signal delay mechanism (105) operably arranged to delay the generation of signal after activation of said signal generating mechanism (90).本發明有關藥物輸送裝置，包含：外殼(10、16)，具有遠側端及近側端，該外殼被設計成適於承納藥物容器(18)，該藥物容器設有輸送構件(20)或設有用於藥物之輸送的可連接輸送構件；驅動機件(54)，被配置來作用於柱塞桿(58)上，該柱塞桿(58)依序被配置來作用於該藥物容器(18)上，用於提供該藥物之自動輸送；釋放機件(62)，互動式連接至該驅動機件(54)，用於由預先拉緊狀態釋放該驅動機件(54)；信號產生機件(90)，用於產生指示該藥物已被完全輸送的聽得見及/或觸覺及/或視覺信號，該信號產生機件(90)係可操作地連接至該驅動機件，使得其被配置成可在縱長方向中關於該驅動機件(54)運動，該驅動機件(54)係配置有信號釋放機件(111)，該信號釋放機件能夠在釋放該驅動機件之後於該驅動機件的一特定縱長位置啟動該信號產生機件(90)，用於產生聽得見及/或觸覺及/或視覺信號，其中該信號產生機件(90)包含信號延遲機件(105)，其可操作地配置來在啟動該信號產生機件(90)之後延遲信號的產生。
