A needleless port system for depositing a sample of biological material into a vacuum container. The system comprises a generally dome-shaped or bell-shaped housing having an upper end and a bottom end, the latter being designed and configured to axially engage a vacuum container receivable therethrough. The system further includes at least one passageway, preferably disposed along a top portion thereof, for establishing fluid communication with a source of biological material. The system further preferably includes a hollow, generally spike-shaped member for depositing the biological sample into the vacuum container. Axially disposed within the housing and axially received about the generally spike-shaped member is a seal member designed and configured to penetrably and sealingly receive the distal tip of the spike member. The seal member is preferably designed and configured to selectively control the amount of biological material drawn into the vacuum container.

An apparatus for depositing a sample of biological material into a vacuum container having a septum comprising: (a) a bell-shaped housing having an open end for axially engaging with said septum of said vacuum container; (b) at least one passageway disposed within said housing, said at least one passageway having a distal end through which said sample of biological material is passed into said vacuum container, said distal end of at least one passageway having means for penetrating said septum; (c) a seal member affixed within said housing, said seal member axially sealing said distal end of said at least one passageway; (d) wherein when said septum and said vacuum container are axially advanced into said opened end of said housing, said septum forces said seal member to axially retract about said distal end of said at least one passageway such that said distal end of said at least one passageway penetrates said septum of said vacuum container and allows said sample of biological material to be deposited within said vacuum container; (e) wherein when said septum and said vacuum container are withdrawn from said opened end of said housing, said seal member axially advances about said distal end of said at least one passageway such that said passageway through which said sample of biological material is passed into said vacuum container is closed off; (f) wherein said distal end of said at least one passageway comprises a hollow, spike-shaped member, said spike-shaped member being oriented toward said septum of said vacuum container; and (g) wherein seal member is fabricated from elastic material and is oriented such that said seal is biased toward said distal end of said at least one passageway such that said seal member continuously acts to close off said passageway through which said sample of biological material is deposited into said vacuum container.
