An Injection device (1) for administering a dose of a liquid medicament (M) to a patient comprises - a syringe (3) containing the dose of the medicament (M) - a hollow injection needle (4) adapted to penetrate the skin of the patient, - a stopper (6) translatably disposed within the syringe (3), - a plunger (9) connectable to the stopper (6) and translatable in at least a proximal direction (P) to displace the stopper (6) in the proximal direction (P) and - a releasable noise component (28) capable of, upon release, generating an audible and/or tactile feedback.The proximal displacement of the stopper (6) causes the dose of the medicament (M) to be expelled through the hollow injection needle (4). The noise component (28) is released when the plunger (9) reaches a position relative to the syringe (3) in which the stopper (6) is located in proximity of a proximal end of the syringe (3). The released noise component (28) impacts on at least one component of the injection device (1) to generate the audible and/or tactile feedback indicating the end of the injection.一種注射裝置(1),用以供給一劑量之一液態藥物(M)給一患者,包含:-一注射器(3),包含此劑量之藥物(M)-一中空注射針部(4),適合於刺穿患者之皮膚,-一阻塞器(6),可平移地配置在注射器(3)之內,-一柱塞(9),可連接至阻塞器(6),且可朝至少一近端方向(P)平移,用以朝近端方向(P)移走阻塞器(6),以及-一可釋放的聲響元件(28),能夠在釋放之時產生一可聽見及/或觸覺回饋。阻塞器(6)之近端位移導致此劑量之藥物(M)經由中空注射針部(4)被排出。聲響元件(28)係在柱塞(9)到達與注射器(3)相關聯的一位置時被釋放,於其中阻塞器(6)係位於注射器(3)之一近端附近。釋放的聲響元件(28)撞擊注射裝置(1)之至少一元件以產生表示注射結束之可聽見及/或觸覺回饋。1‧‧‧自動注射器2‧‧‧機架3‧‧‧注射器4‧‧‧中空注射針部5‧‧‧保護針部屏蔽6‧‧‧阻塞器7‧‧‧載體7.5‧‧‧第二凹槽8‧‧‧驅動彈簧9‧‧‧柱塞10‧‧‧載體末端面11‧‧‧止推面12‧‧‧容器12.3‧‧‧第一肋12.4‧‧‧第一背後阻塞物13‧‧‧觸發按鈕14‧‧‧樁15‧‧‧彈臂17‧‧‧遠端柱塞套筒18‧‧‧掣爪機構19‧‧‧控制彈簧20‧‧‧第一軸環21‧‧‧第二軸環22‧‧‧蓋體22.1‧‧‧內部套筒23‧‧‧倒鉤24‧‧‧針部插入控制機構27‧‧‧柱塞釋放機構28‧‧‧聲響元件29‧‧‧聲響彈簧D‧‧‧末端、遠端方向P‧‧‧近端、近端方向
