The complicated passage design it does not need, without forming the liquid picking device of the pump and the passage tube separately, in addition, it designates that the functional narrow tube device which can correspond to various applications is offered as topic. As for functional narrow tube device 1, inside air shell this touching to the aforementioned shell in outer circle of 2 and this shell with interval according to axis direction, the plural vibrating ring bodies it had with the energy supply expedient 4 which supplies the energy which vibrates 3 which are provided and this vibrating ring body, the aforementioned energy supply expedient, in order for the displacement quantity of the vibration to differ mutually in the aforementioned vibrating ring body, made the constitution which gives energy.複雑な流路設計を必要とせず、ポンプと流路管の液体採取デバイスを別々に構成することなく、また、多様なアプリケーションに対応することができる機能細管装置を提供することを課題とする。機能細管装置1は、内部が中空な管体2と、この管体の外周に軸線方向に沿って間隔をもって前記管体に当接して設けられた複数の振動リング体3と、この振動リング体を振動させるエネルギを供給するエネルギ供給手段4とを備え、前記エネルギ供給手段は、前記振動リング体に振動の変位量が互いに異なるようにエネルギを与える構成とした。
