As for this invention, as for the above-mentioned device, it is arranged in the container and the above-mentioned container which insert the medicine in regard to the damper for the medicine delivery device, it possesses the proximal edge and the distal (2036) edge which oppose with portable possible stopper, in order to discharge the above-mentioned medicine through dosage quantitative delivery expedient, it has with the power expedient which can be able to use power in the plunger rod and the above-mentioned plunger rod which can operate the above-mentioned stopper. The above-mentioned damper has the tubular sleeve which possesses the proximal edge and the distal (2036) edge which oppose, the above-mentioned sleeve in the proximal edge of the sleeve, with the end wall and the division which was formed the proximal edge is closed of the plunger rod which is positioned in the open edge in the distal (2036) edge of the sleeve by is had. The above-mentioned division is seal possible and the above-mentioned plunger rod moves when and due to the pad and the fluid and the above-mentioned sleeve of elasticity and discharging the above-mentioned fluid in the annular space between the inner walls of the above-mentioned container, in order to generate attenuation power it has with one passage at least.本発明は、薬剤送達装置のためのダンパに関し、上記装置は、薬剤を入れる容器と、上記容器に配置され、投与量送達手段を通して上記薬剤を排出するために移動可能なストッパと、対向する近位端および遠位端を有し、上記ストッパに作用することができるプランジャロッドと、上記プランジャロッドに力を働かせることができる力手段とを備える。上記ダンパは、対向する近位端および遠位端を有する管状スリーブを備え、上記スリーブは、スリーブの近位端における閉じた端部壁と、スリーブの遠位端における開放端に位置決めされるプランジャロッドの近位端とによって形成された区画を備える。上記区画は、封止可能でありかつ弾性のパッドと、流体と、上記スリーブおよび上記容器の内壁の間の環状空間の中の上記流体を排出することによって、上記プランジャロッドが移動すると減衰力を発生させるための少なくとも1つの通路とを備える。
