FOR: BLOOD COLLECTION ASSEMBLY
BACKGROUND OF THE I~YE~TION
1. Field of the In~ention This invention relates to barrier coatings and barrier labels for providing an effective barrier against gas and water permeability for containers, especially plastic evacuated blood collection tubes.
FOR: BLOOD COLLECTION ASSEMBLY
BACKGROUND OF THE I~YE~TION
1. Field of the In~ention This invention relates to barrier coatings and barrier labels for providing an effective barrier against gas and water permeability for containers, especially plastic evacuated blood collection tubes.
2. Description of the Related Art With the increased emphasis on the use of plastic medical products, a special need exists for improving the barrier properties of articles made of polymers.
Such medical products that would derive a considerable benefit from improving their barrier properties include, but are not limited to, collection tubes and particularly those used for blood collection.
Blood collection tubes require certain pérformance standards to be acceptable for use in medical applications. Such performance standards include the ability to maintain greater than about 90% original draw volume over a one year period, to be radiation sterilizable and to be noninterfering in tests and analysis.
A critical performance standard of the blood collection tube is the draw volume retention. Draw volume retention depends on the existence of a partial - . , . . ~
- . . : , - :
. .
210027~
vacuum, or reduced pressure, inside the tube. The draw volume changes in direct proportion to the change in vacuum (reduced pressure~. Therefore, draw volume retention is dependent on good vacuum retention.
For example, it is important to maintain the vacuum over a period of time in order to provide appropriate storage life for those tubes prior to their being used. That is, it is important for the vacuum level to be maintained for a period of time prior to the time when a technician or a nurse uses the tube for collecting a blood sample.
Radiation sterilizable means that after the tube is exposed to certain levels of radiation in the sterilization process, there is substantially no change in optical or mechanical and functional properties.
Noninterference in performance of a tube's specifications means that the materials of the tube, such as glass or plastic materials do not interfere with testing and analysis that is typically performed on blood in the tube. Such tests include but are not limited to, hematology, blood chemistry, blood typing, toxicology analysis ~nd therapeutic drug monitoring.
Furthermore, the tube must be capable of being subjected to automated machinery such as centrifuges.
Therefore, a need exists to improve the barrier properties of articles made of polymers and in particular plastic evacuated blood collection tubes wherein such improvement does not obscure the contents ;~ of the articles, certain performance standards would be able to be met and the article would be effective and usable in medical applications.

SUMMARY O~ IE INV~TION
The present invention is a plastic composite container coated with a barrier composition or barrier label disposed over an outer surface of the composite container. That is, a barrier composition is coated over the previously formed plastic container or a barrier label coated with a barrier composition is disposed over the outer surface of the composite container. Such a barrier composition or barrier label improves the barrier properties of plastic containers, does not obscure the contents of the plastic containers and extends the shelf-life of plastic containers, especially plastic evacuated blood collection devices.
A desirable barrier composition which can be disposed over a plastic container or a barrier label, preferably comprises a diamond composition. A diamond composition may be applied either to an interior surface portion or to an exterior surface portion of the container or label.
Desirably, the barrier label may be placed or formed around the container and then adhered to the container by methods such as, but not limited to, an adhesive layer, heating the barrier label and container to a temperature sufficient to cause the barrier label to heat-shrink onto the container or by expanding the container into the barrier label by blow molding.
Desirably the barrier label of the present invention is a polymer film with a diamond composition coating.
Preferably, the diamond composition provides a transparent, translucent or colorless appearance and may have printed matter applied thereon.
Such medical products that would derive a considerable benefit from improving their barrier properties include, but are not limited to, collection tubes and particularly those used for blood collection.

SUMMARY O~ IE INV~TION
The present invention is a plastic composite container coated with a barrier composition or barrier label disposed over an outer surface of the composite container. That is, a barrier composition is coated over the previously formed plastic container or a barrier label coated with a barrier composition is disposed over the outer surface of the composite container. Such a barrier composition or barrier label improves the barrier properties of plastic containers, does not obscure the contents of the plastic containers and extends the shelf-life of plastic containers, especially plastic evacuated blood collection devices.
A desirable barrier composition which can be disposed over a plastic container or a barrier label, preferably comprises a diamond composition. A diamond composition may be applied either to an interior surface portion or to an exterior surface portion of the container or label.
Desirably, the barrier label may be placed or formed around the container and then adhered to the container by methods such as, but not limited to, an adhesive layer, heating the barrier label and container to a temperature sufficient to cause the barrier label to heat-shrink onto the container or by expanding the container into the barrier label by blow molding.

P-2518 21~0~
Plastic tubes or barrier labels coated with the diamond composition are able to maintain far better vacuum retention and draw volume retention than previous tubes comprised of polymer compositions and blends thereof without a barrier coating or label. In addition, the coated or labeled tube's water barrier properties would be significantly improved since diamond coatings are substantially non-polar. Notably is the clarity of the diamond composition, its durability to substantially withstand resistance to impact, abrasion and scratches.
Suitable films to be coated for use as barrier labels according to the present invention include, but are not limited to polypropylene films, low and high density polyethylene films and polyvinylchloride films.
Printing may be placed on the barrier composition or label which is to be used on the container of ~ interest. For example, a product identification, bar code, brand name, company logo, lot number, expiration date and other data and information may all be included on the label surface. Moreover, a matte finish or a corona discharged surface may be developed on the outer surface of the barrier composition so as to make the surface appropriate for writing additional information on the label. Furthermore, another pressure sensitive adhesive label may be placed over the outer surface of the barrier label so as to accommodate various hospital over-labels, for example.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a typical blood collection tube with a stopper.
FIG. 2 is a longitudi ~ 2t~i~nal view Or the tube of FIG. 1 taken along line 2-2.
FIG. 3 is a longitudinal sectional view of a tube-shaped container similar to the tube of FIG.
without a stopper.
FIG. 4 is a longitudinal sectional view of a tube-shaped container similar to the tube of FIG. 1 with a stopper.
DETAILED DESCRIPTION
Referring to the drawings in which like reference characters refer to like parts throughout the several views thereof, FIGS. 1 and 2 show a typical blood collection tube 10, having an open end 16, a closed end 18 and stopper 14 which includes a lower annular portion or skirt 15 which extends into and presses against the inside walls 12 of the tube for maintaining stopper 14 in place. FIG. 2 schematically illustrates that there are three mechanisms for a change in vacuum in a blood collection tube: ~A) gas permeation through the stopper material; (B) gas permeation through the tube material and (C) leak at the closure-tube interface. Therefore, when there is substantially no gas permeation and no leak, there is good vacuum retention and good draw volume retention.
FIG. 3 shows the preferred embodiment of the invention, a plastic tube coated with a diamond composition or covered by a diamond coated barrier label. The preferred embodiment includes many components which are substantially identical to the components of FIGS. 1 and 2. Accordingly, similar - . . .
- - - . -P-2518 210~27~
components performing similar functions will be numbered identically to those components of FIGS. 1 and 2, except that a suffix "a" will be used to identify those components in FIG. 3.
Referring now to FIG. 3, the preferred embodiment of the invention, collection tube assembly 20 comprises a plastic tube lOa, having an open end 16a and a closed end 18a. A coating comprising a diamond composition or diamond coated barrier label 25 extends over a substantial portion of the length of the tube which is upon the outer surface of the tube with the exception of open end 16a and closed end 18a thereof.
FIG. 4 illustrates an alternate embodiment of the invention, wherein collection tube assembly 40 comprises stopper 48 in place for closing open end 41 of tube 42. As can be seen, stopper 48 includes an annular upper portion 50 which extends over the top edge of tube 42. Stopper 48 includes a lower annular portion or skirt 49 which extends into and presses against the inside walls of tube 42 for maintaining stopper 48 in place and also, defines a well 52 which, in turn, defines a septum portion 53 ~5 for receiving a cannula therethrough. Thus, the user, once receiving a container such as that shown in FIG. 4 with a sample contained therein, may insert a cannula through septum 53 for receiving part or all of the contents in tube 42 to perform various tests on a sample.
.
Covering a substantial portion of the length of the tube is a coating comprising a diamond composition or diamond coated barrier label 45. The coating or barrier label 45 covers substantially most of the tube ~ r P-2518 2~Q027~
with the exception of open end 41 thereof. FIG. 4 differs from the embodiment in FIG. 3 in that the tube may be evacuated with the simultaneous placement of stopper 48 therein after the application of a diamond coating or diamond coated barrier label 45 thereover the tube. Alternatively, the diamond coating or diamond coated barrier label may be applied to the tube before it has been evacuated.
10An alternate embodiment of the invention also includes a coating or label incorporating both the upper portion of the stopper, as well as the entire container - tube. Such an embodiment may be utilized, for example, for sealing the container with the stopper in place.
Once a sample has been placed in the tube, the sample cannot be tampered with by removal of the stopper.
Additionally, serrations could be included at the tube, stopper interface. The serrations may be registered so that it can be determined if the sealed container has been tampered with.
It will be understood by practitioners-in-the-art, such tubes may contain reagents in the form of additives or coatings on the inner wall of the tube.
A coating comprising a diamond composition forms a clear or translucent barrier. Therefore, the contents of a plastic tube coated with a coating comprising a diamond composition are visable to the observer at the same time identifying information may be displayed o~er the diamond film after it is applied to the plastic tube.
A coating comprising a diamond composition may be formed on a substrate by radio frequency discharge, direct or dual ion beam depos~tion, sputtering or plasma .
