PROBLEM TO BE SOLVED: To provide a safe implement capable of aspirating nasal discharge by just operating a pump with it held in hand and further, preventing injury of a mucous membrane of a nasal cavity.SOLUTION: A nasal aspirator includes: a pump that is compressed/restored by a manual operation; a cylindrical connecting tube inserted into an opening of the pump; and a nozzle body that is fitted to an upper opening of the connecting tube, where the lower part thereof is communicated to the pump. The nozzle body is extended in a state where an upper-side inside diameter is narrowed. The connecting tube includes, at a part thereof, a check valve for shutting off the inflow from the outside, while the nozzle body includes, at a base end part thereof, a check valve for shutting off the outflow from the pump to the nozzle body.SELECTED DRAWING: Figure 4 【課題】 手に持った状態でポンプを操作するだけで鼻水を効果的に吸引することができ、しかも鼻腔内部の粘膜などを損傷することがない安全な器具を提供する。【解決手段】 手の操作で収縮復元するポンプと、このポンプの開口に挿通した円筒状の接続筒と、この接続筒の上側開口に嵌合し、下部が前記ポンプと連通するノズル本体とからなり、このノズル本体は上側内径を狭めた状態で延長しており、前記接続筒の一部には外部からの流入を遮蔽する逆止弁を設ける一方、前記ノズル本体の基端部には前記ポンプから前記ノズル本体への流出を遮蔽する逆止弁を設けた鼻水吸引器具である。【選択図】 図４
