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. |
