ABSTRACT:
The present invention pertains to a fluid aspiration-collection apparatus for aspirating and collecting a fluid into a suction chamber through a fluid inlet communicating with the suction chamber in the case, and for discharging the fluid through a fluid outlet after completion of fluid aspiration. A primary object of the present invention is to provide an apparatus which is simple in construction and is capable of aspirating the fluid at a constant pressure. The apparatus of the present invention comprises a case having a suction chamber formed, interior of which communicates with a fluid inlet and a fluid outlet, a moving plate constituting a part of a wall section of the suction chamber and movably disposed within the case; and a cylinder in which a piston is airtightly and movably inserted and in which a vacuum chamber is created by relative movement of the piston or itself; the piston and the moving plate being connected to move together; the cross sectional area of the piston being set smaller than the projected area in the direction of movement of the moving plate; and the back side of the piston and the moving plate communicating with the atmosphere.
