Abstract: A self-contained vacuum aspirator system is disclosed which comprises a container having a vacuum applied therein; a valve assembly secured to said container for selectively allowing the passage of fluid into said container; a curette in communication with an aperture in said valve assembly; and an air permeable collection means supported within said container by the aforementioned valve assembly in communication with an opening in said valve assembly for accumulating matter collected by said currette when the valve assembly is operating to establish communication between the aforementioned aperture and opening. The valve assembly includes a first member having the aforementioned aperture therethrough with the first member having a first surface on which is positioned first sealing means surrounding said aperture and second sealing means surrounding said first sealing means; and a second member secured to said first member with the second member having the aforementioned opening therethrough and a first surface on which is positioned third sealing means surrounding said opening and fourth sealing means surrounding said third sealing means; and a slide member having a passageway therethrough with the slide member being moveably mounted between said first surfaces of the first and second members and sealingly engaged on opposite sides thereof by the first, second, third and fourth sealing means, with the slide member being moveable between a first position which interrupts communication between said aperture and said opening and a second position in which the passageway through the slide member establishes communication between the aperture in the first member and the opening in the second member to permit flow through the valve assembly.
