摘要：
Described is an injection device (1) for administering a dose of a medicament (M) comprising a carrier (7) adapted to contain a syringe (3) having a hollow injection needle (4) and a stopper (6), a drive spring (8), a plunger (9) adapted to forward load of the drive spring (8) to the stopper, and a noise component (28) adapted to generate an audible and/or tactile feedback by impacting a component of the injection device (1) when the stopper (4) is located at a proximal end of the syringe (3). In a first state, a resilient arm (30) on the plunger (9) is maintained in engagement with the noise component (28) by the carrier (7). In a second state, the arm (30) disengages the noise component (28) and deflects at least partially into an aperture (7.22) in the carrier (7).本發明係描述一用於施用一劑量的一藥物(M)之注射裝置(1),該注射裝置(1)係包含一載體(7),其調適以含有一針筒(3),針筒(3)具有一中空注射針頭(4)及一停止器(6),一驅動彈簧(8),一柱塞(9),其調適以將驅動彈簧(8)的負荷遞交至停止器,及一噪音組件(28),其調適以藉由當停止器(4)位居針筒(3)的一近端時衝擊注射裝置(1)的一組件來產生一聽覺及/或觸覺回饋。在第一狀態,柱塞(9)上的一韌性臂(30)係藉由載體(7)維持接合於噪音組件(28)。在第二狀態,臂(30)係脫離噪音組件(28)並至少部份地撓曲至載體(7)中的一開孔(7.22)中。7‧‧‧載體7.22‧‧‧開孔9‧‧‧柱塞28‧‧‧回饋組件28.1‧‧‧長形部分28.3‧‧‧往外的第十一斜坡30‧‧‧第二韌性臂30.1‧‧‧斜坡狀內轂31‧‧‧回饋釋放機構D‧‧‧遠端/遠向方向O‧‧‧往外方向P‧‧‧近端/近向方向
