Abstract

A body fluid collection assembly includes a tube having an outside surface, an open end and a closed end forming a chamber having an inside wall for holding a body fluid, the tube has a raised annulus at the open end. The assembly includes a closure with a shield having a top, an opening therethrough and a cavity for receiving the open end of the tube. The cavity has an inside surface having at least one protuberance projecting inwardly from the inside surface so that when the open end of the tube is in the cavity, the protuberance engages said annulus retaining said shield on the tube. The assembly includes a sealing element having a top surface and a lower flange and a gas barrier member bonded to the lower flange to form a primary seal with the inside wall of the tube and a secondary seal at the open end of the tube. The assembly further includes a plug housing having a passage and a resilient plug mounted in the passage, and elements for releasably mounting the plug housing on the shield.

Claims

1. A closure for sealing an open end of a body fluid collection tube comprising:

a shield having a top, an opening therethrough and a cavity for receiving the tube;

a sealing element for sealing the tube, said element having a top surface and a lower flange, said top surface being received in said opening;

a gas barrier member bonded to said lower flange of said sealing element to form a primary seal with an inside wall of the tube and a secondary seal at the open end of the tube;

a plug housing having a passage therethrough, said housing having an outside wall;

a resilient plug having a bottom mounted in said passage;

a pivot post and a lock post projecting upwardly from said top of said shield; and

a projection extending outwardly from said outside wall of said housing and a clasp opposite said projection extending outwardly from said outside wall of said housing, said projection having an opening for receiving said pivot post, said clasp for engaging said lock post, said plug housing being rotatable about said pivot post between a first position and a second position, said first position at which said bottom surface of said plug contacts said top surface of said sealing element and said clasp engages said lock post, said second position exposing said top surface of said sealing element and at which said clasp is not engaging said lock post.
