A two body syringe carrier assembly for use in an injection device is presented where a force dampener is operatively connected to the two bodies to dissipate spring force at the completion of the penetration and/or injection steps. The injection device has a generally elongated tubular housing, a syringe containing medicament and having a needle, a needle shield slidably arranged to the housing and protruding a distance outside the front end of the housing, a plunger arranged to act on the syringe and a pre-tensioned drive member arranged the drive the plunger.供使用於注射裝置中之雙本體注射器載體總成被呈現，在此力量阻尼器係操作地連接至該雙本體，以在該穿透及/或注射步驟的完成處耗散彈簧力量。該注射裝置具有大致上修長之管狀外殼、含有藥物及具有針的注射器、可滑動地配置至該外殼及在該外殼的前端外側突出一段距離之針屏蔽件、配置來作用在該注射器上的柱塞、及配置來驅動該柱塞之預先拉緊的驅動構件。
