    • The present invention miniaturizes an entire device. In the present invention, a piston 21 is arranged at an initial position where the piston is further pulled back from a pulled-back position and where a part of a front end part 21A formed in a truncated cone shape contacts with a packing 27 along a circumferential direction in an initial state. The amount of the squeeze of the packing 27 is reduced when the piston 21 is located at the initial position by pulling back and locating the piston 21 before medical solution is inserted into a medical solution storage unit 6. Therefore, a contact resistance can be reduced than that in a case where the packing 27 contacts with a body 21B of the piston 21. Accordingly, it is not necessary to use a large force to start the piston by receiving a starting resistance at the time of starting the use of it, and the entire device can be miniaturized.
    • 本发明使整个装置小型化。 在本发明中,活塞21布置在活塞从拉回位置进一步拉回的初始位置处,并且形成为圆锥台形状的前端部21A的一部分沿着 在初始状态下沿圆周方向。 通过在将药液插入药液收纳部6之前将活塞21拉回并定位,活塞21位于初始位置时,密封件27的挤压量减少。因此,能够降低接触电阻 比在密封件27与活塞21的本体21B接触的情况下的密封性能好。因此,在开始使用时不需要用大的力通过接收启动阻力来启动活塞,并且 整个设备可以小型化。
