Abstract

Abstract A stopper for medical containers such as blood collection tubes having integral flange and plug portions, the flange portion being substantially larger in diameter than the plug portion, which plug portion is sized to sealably close the container. The stopper has opposed wells formed in the flange and plug portions, the well in the flange portion having a relatively flat bottom surface at least as large in diameter as the diameter of the opposed well in the plug portion. The flange portion is constructed to be guided into a tube holder into which it is inserted such that one end of a needle projecting into the interior of the tube holder will penetrate the stopper in the area of the opposed wells so as to avoid otherwise contacting the stopper. The enlarged flange portion also serves to facilitate removal of the stopper from the container without contaminating a handler.

In combination, a blood collection tube and a stopper for use with a holder, the holder having an inside surface, an open end, a closed end and a hollow needle extending axially from the closed end of the holder toward the open end of the holder, the combination comprising: a hollow elongated blood collection tube having an open end, and a stopper body having flange and plug portions, said plug portion of said stopper body sealably positioned within said open end of said blood collection tube, the largest outside diameter of said flange portion of said stopper body being less than the inside diameter of the holder body, and said flange portion being greater than the largest outside diameter of the blood collection tube proximate said open end of said tube by a factor of at least 1.4 whereby, when said plug portion is inserted into said open end of said blood collection tube and said stopper and said blood collection tube is placed through the open end of the holder, said stopper is constrained within the holder and forced to be concentrically aligned with the needle by the inside surface of the holder.
Claim 2
Dependent Claim 194 words
In combination, a blood collection tube and a stopper for use with a holder, the holder having an inside surface, an open end, a closed end and a hollow needle extending axially from the closed end of the holder toward the open end of the holder, the combination comprising: a hollow elongated blood collection tube having an open end, and a stopper body having flange and plug portions, said plug portion of said stopper body sealably positioned within said open end of said blood collection tube, the largest outside diameter of said flange portion of said stopper body being less than the inside diameter of the holder body, and said flange portion being greater than the largest outside diameter of the blood collection tube proximate said open end of said tube by a factor of at least 1.4 whereby, when said plug portion is inserted into said open end of said blood collection tube and said stopper and said blood collection tube is placed through the open end of the holder, said stopper is constrained within the holder and forced to be concentrically aligned with the needle by the inside surface of the holder.
Claim 3
Dependent Claim 54 words
The combination of claim 1 wherein said blood collection tube has a substantially uniform outside diameter over the length thereof, said tube outside diameter being substantially smaller than the inside diameter of the holder, and said flange portion of said stopper body being substantially larger in diameter than the outside diameter of said tube.
Claim 4
Dependent Claim 36 words
The combination of claim 1 wherein said stopper body includes means forming aligned and opposed cavities in said flange and plug portions of said stopper body to define a diaphragm portion of said stopper body therebetween.
Claim 5
Dependent Claim 45 words
The combination of claim 1 wherein the largest outside diameter of said flange portion of said stopper body exceeds the largest outside diameter of said blood collection tube proximate said open end of said tube by a factor of from about 1.6 to about 1.8.
Claim 6
Dependent Claim 53 words
The combination of claim 1 wherein the outer diameter of said tube is about 10 millimeters and the largest outer diameter of said flange portion of said stopper body is from about 16.8 to about 17.8 millimeters, and the inside diameter of the holder is from about 16.9 millimeters to about 18.3 millimeters.
Claim 7
Dependent Claim 145 words
In combination, an open blood collection tube, a stopper for closing the tube, and a holder for receiving the stopper and tube, comprising: a tubular holder body having an open end and having a hollow needle extending axially from an opposite end of said holder body toward said open end of said holder body, a hollow elongated blood collection tube having an open end, and a stopper body having flange and plug portions, said plug portion of said stopper body sealably positioned within said open end of said blood collection tube, and the largest outside diameter of said flange portion of said stopper body being less than the inside diameter of said holder body, and said flange portion being greater than the largest outside diameter of the blood collection tube portion proximate said open end of said tube by a factor of at least 1.4.
Claim 8
Dependent Claim 145 words
In combination, an open blood collection tube, a stopper for closing the tube, and a holder for receiving the stopper and tube, comprising: a tubular holder body having an open end and having a hollow needle extending axially from an opposite end of said holder body toward said open end of said holder body, a hollow elongated blood collection tube having an open end, and a stopper body having flange and plug portions, said plug portion of said stopper body sealably positioned within said open end of said blood collection tube, and the largest outside diameter of said flange portion of said stopper body being less than the inside diameter of said holder body, and said flange portion being greater than the largest outside diameter of the blood collection tube portion proximate said open end of said tube by a factor of at least 1.4.
Claim 9
Dependent Claim 40 words
