A closed specimen collection system for blood samples includes a collection tube that has a shaped nozzle adapted to fit sealably into a port connected to a centrally inserted venal catheter. A protective cover for the nozzle is attached to the collection tube and has an internal, female thread that mates to a male thread on the port. A specimen container has a hollow body, a front end and a back end. The front end has an aperture sized and shaped to attach to the collection tube. The aperture is sealable after removal of the collection tube. A piston fits closely within the hollow body and is attached to an actuating rod. When the port is connected to the collection tube, the collection tube is connected to the specimen container and the actuating rod is pulled toward the back end, blood will flow into the container in a sterile condition.

1. A closed specimen collection system, comprising: a collection tube, said collection tube having a proximal end and a distal end and having a blunt, shaped nozzle at said proximal end;said shaped nozzle being adapted to fit sealably into a port connected axially to a distal end of a centrally inserted venal catheter;a protective cover, said cover being attached to said collection tube adjacent said proximal end, said cover having a hollow interior and extending outwardly from a base of said shaped nozzle a first predetermined distance;said cover having an internal, female thread, said female thread mating to a male thread on said port;a specimen container, said container having a hollow body, a front a back end and a longitudinal axis;said front end having an aperture, said aperture being sized and shaped to attach to said distal end of said collection tube, an integral axially rotating lid, said lid rotating about said longitudinal axis and sealing said aperture after removal of said distal end of said collection tube;a latching mechanism, said latching mechanism controlling rotation of said lid;a piston, said piston fitting closely within said hollow body and being attached to an actuating rod; andwhereby, when said port is connected to said collection tube, said collection tube is connected to said specimen container and said actuating rod is moved away from said front end of said container, blood will flow into said specimen container in a sterile condition. 2. The closed specimen collection system, as described in claim 1, wherein said protective cover further comprises at least one lever to assist in attaching said cover to said port. 3. The closed specimen collection system, as described in claim 1, wherein said front end of said specimen container further comprises a sample opening, said opening being sealed with a rubber membrane, said membrane adapted to accommodate needle penetration. 4. The closed specimen collection system, as described in claim 1, wherein said latching mechanism further comprises: a rotating portion, said rotating portion affixed to a leading edge of said rotating lid, said rotating lid rotating to seal said aperture, and having a projecting ledge disposed parallel to said leading edge;a fixed portion, said fixed portion affixed to said front end of said specimen container, having a receiving slot sized, shaped and disposed to mate frictionally with said projecting ledge; andwhereby, when said rotating lid is positioned to seal said aperture, said projecting ledge will be secured within said receiving slot. 5. The closed specimen collection system, as described in claim 4, wherein said latching mechanism further comprises a retracting tab attached to said rotating portion, said retracting tab assisting in opening said aperture. 6. The closed specimen collection system, as described in claim 1, wherein said piston further comprises: a seal, said seal having a front side and a back side and being sized and shaped to fit closely within said hollow body and disposed adjacent said front end of said specimen container;said seal, having a central receiving port disposed at a center portion thereof;a first end of said actuating rod being sized and shaped to removably engage said central receiving port; andwhereby, when said actuating rod has withdrawn said piston toward said back end of said specimen container, said actuating rod is removed from said receiving port and when said aperture is sealed said specimen container will contain a sterile blood sample. 7. The closed specimen collection system, as described in claim 1, wherein said piston further comprises: a first seal, said first seal having a front side and a back side and being sized and shaped to fit closely within said hollow body and disposed adjacent said front end of said specimen container;a second seal, said second seal being sized and shaped to fit closely within said hollow body and having a central receiving port penetrating a center portion of said second seal;said second seal being spaced from said back side of said first seal and attached thereto at an outer surface of said receiving port;a first end of said actuating rod being sized and shaped to removably engage said central receiving port; andwhereby, when said actuating rod has withdrawn said piston toward said back end of said specimen container, said actuating rod is removed from said receiving port, said aperture is sealed and said specimen container will contain a sterile blood sample. 8. The closed specimen collection system, as described in claim 7, wherein said actuating rod has a male thread at said first end and said central receiving port has a mating female thread. 9. The closed specimen collection system, as described in claim 1, wherein said distal end of said collection tube has an external thread and said aperture disposed at said front end of said specimen container has a mating internal thread. 10. The closed specimen collection system, as described in claim 1, wherein said specimen container further comprises a sterile culture medium.
