The present invention relates to a medicament delivery device comprising a medicament container (52) having an attached medicament delivery member (54) a housing adapted to receive the medicament container (52), the medicament container (52) being movable between a retracted position in which the medicament delivery member (54) is contained within the housing and an extended position in which the medicament delivery member (54) extends from the housing a drive unit (78) that acts upon the medicament container (52) to advance it from its retracted positon to its extended position and expels its contents through the medicament delivery member (54) and a medicament container holder (50) for carrying the medicament container (52) as it is advanced, the medicament container holder (50) having a proximal end through which the medicament delivery member (54) extends and a distal end opposite the proximal end and a holding member (80) releasably connected to the drive unit and attached to the medicament container holder. The invention is characterized in that the holding member (80) comprises, at its proximal end a biasing element (90) arranged to bias the medicament container (52) in the proximal direction in the medicament container holder (50) and wherein the biasing element (90) comprises a resilient structure in the form of a tubular wall (82) provided with slots (92) extending in the generally circumferential direction.本發明有關藥物輸送裝置,包含藥物容器(52),具有一被附接的藥物輸送構件(54);外殼,被設計成適於承接該藥物容器(52),該藥物容器(52)係可於縮回位置與延伸位置之間運動,該藥物輸送構件(54)係在該縮回位置中被容納於該外殼內,且該藥物輸送構件(54)在該延伸位置中由該外殼延伸;驅動單元(78),其作用於該藥物容器(52)上,以將該藥物容器由其縮回位置推進至其延伸位置,並經過該藥物輸送構件(54)排出其內容物;及藥物容器夾具(50),用於當其被推進時承載該藥物容器(52),該藥物容器夾具(50)具有該藥物輸送構件(54)延伸經過的近側端及相向於該近側端之遠側端;及固持構件(80),可釋放地連接至該驅動單元及附接至該藥物容器夾具。本發明的特徵為該固持構件(80)在其近側端包含被配置來使該藥物容器(52)偏向於該藥物容器夾具(50)中的近側方向中之偏向元件(90),且其中該偏向元件(90)包含呈管狀壁面(82)的形式之彈性結構,該管狀壁面設有在該大致上圓周方向中延伸之凹槽(92)。10‧‧‧外殼12‧‧‧近側端14‧‧‧遠側端16‧‧‧端部件22‧‧‧凹部32‧‧‧藥物輸送構件防護件50‧‧‧藥物容器夾具52‧‧‧藥物容器60‧‧‧藥物輸送構件遮蔽件78‧‧‧驅動單元130‧‧‧端蓋146‧‧‧凹部1
