PROBLEM TO BE SOLVED: To provide a technique capable of efficiently generating a suction pressure with a simple configuration.SOLUTION: A body fluid sucking pump has: an inlet port for allowing a body fluid to be sucked a container for receiving the body fluid a reverse flow prevention valve connected to the inlet port in the container an outlet port for allowing the sucked body fluid to be discharged and a cylindrical restoring means which is internally provided in the container body and generates a suction pressure in the container by restoring the shape of the container which has been compressed after compressing the container. In the pump, the restoring means is made of non-metal, the reverse flow prevention means and the restoring means are installed so that the axial direction of the reverse flow prevention means is substantially in parallel with that of the cylinder of the restoring means, and the reverse flow prevention means moves in a direction away from the restoring means when the restoring means is compressed.COPYRIGHT: (C)2013,JPO&INPIT【課題】シンプルな構造で効率的に吸引圧を発生し得る技術を提供すること。【解決手段】体液が吸入される吸入口と、体液を受け入れるための容器と、前記容器内で前記吸入口に接続される逆流防止弁と、吸入された体液が送出される送出口と、前記容器内に内設され、前記容器を圧縮した後に圧縮された形状が復元することで前記容器内に吸引圧を発生させる筒状の復元手段と、を備え、前記復元手段が、非金属材料により形成され、前記逆流防止弁と前記復元手段とは、前記逆流防止弁の軸方向と前記復元手段の筒の軸方向とがほぼ平行になるように設置されており、前記復元手段圧縮された際に、前記逆流防止弁が前記復元手段から離れる方向に移動する体液吸引用ポンプを提供する。【選択図】図1
