Needleless vacuum container port system
First Claim
1. A needleless vacuum container port system comprising:
- a) a bell-shaped housing having a top end and an open bottom end, said open bottom end being designed and configured to receive a vacuum container, said housing having at least one passageway disposed along said top portion thereof for establishing fluid communication with a source of biological material, said at least one passageway having a hollow spike member depending within said housing to establish fluid communication between said source of biological material and said vacuum container;
b) an elastic seal member axially affixed about said open bottom end of said housing and disposed intermediate said housing and said vacuum container when said vacuum container is engaged with said housing, said seal member being designed and configured to axially retract about said hollow spike member such that, in use, a resealable closure is formed about said at least one passageway;
c) an annular member attachable to said open bottom end of said housing, said annular member being shaped and designed to allow said vacuum container to pass therethrough, said annular member being designed and configured to interconnect with said housing such that said interconnection provides means for axially affixing said seal member to said housing; and
d) wherein when said vacuum container is inserted and withdrawn from said open bottom end of said housing, said insertion into said housing simultaneously urges said seal member to axially retract about said spike member and forces said spike member to penetrate into said vacuum container such that fluid communication between said source of biological material and said vacuum container is established and a portion of said biological material is drawn into said vacuum container, said withdrawal of said vacuum container from said bottom end of said housing simultaneously retracting said spike member from said vacuum container and allowing said seal member to axially advance about said spike member such that said fluid communication between said source of biological material and said vacuum container is closed off.

Abstract
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.
