Abstract

Abstract This invention relates to a closed system specimen collection container. The collection container is designed to collect, transport and transfer the liquid specimen into a non-evacuated tube through an integrated valve component. This device has no sharp needles and utilizes a blunt cannula component on a test tube. The operation of the device consists of the steps of collecting a specimen into the container and attaching a cap in permanent locking and leak resistant attachment. The cap may be a snap-on or threaded lock. The specimen may then be immediately transported to a laboratory in the container where the specimen can be transferred into a tube for analysis. Alternatively, the specimen may then be immediately transferred into a non-evacuated tube through the integrated valve by a passive means. This technique is accomplished by inserting the blunt cannula attached to the tube into the bottom of the container and interfacing with the integrated valve component. The valve is pierced by the blunt cannula on the tube allowing passive transfer of the specimen without the user coming in contact with the liquid. Gravity allows liquid to transfer automatically. The filled test tube is then pulled off of the container and a second tube may be filled at that time if desired. The container may then be discarded for proper disposal. The integrated valve is a self-sealing valve which allows the user to obtain multiple tube samples without the risk of leaks or spills from the container.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 141 words
A closed system specimen collection container comprising: a container comprising a bottom, an open top, and side walls extending from said bottom to said open top, said bottom comprising a center point, an integrated valve a circular top surface and a bottom surface, said top surface inclined and having an aperture located at a point that is the lowest gravitational point on said top surface; said integrated valve protruding from said bottom surface and offset from the center point of said bottom, said valve in fluid communication with said aperture and allowing multiple sampling such that said valve is opened when said valve is punctured and said valve is closed when the puncture is removed; and a lid disposed around said open top and having a recessed area forming a vent, said vent for allowing air to permeate from said container.
Claim 2
Dependent Claim 141 words
A closed system specimen collection container comprising: a container comprising a bottom, an open top, and side walls extending from said bottom to said open top, said bottom comprising a center point, an integrated valve a circular top surface and a bottom surface, said top surface inclined and having an aperture located at a point that is the lowest gravitational point on said top surface; said integrated valve protruding from said bottom surface and offset from the center point of said bottom, said valve in fluid communication with said aperture and allowing multiple sampling such that said valve is opened when said valve is punctured and said valve is closed when the puncture is removed; and a lid disposed around said open top and having a recessed area forming a vent, said vent for allowing air to permeate from said container.
Claim 3
Dependent Claim 40 words
The specimen collection container of claim 1 , further comprising a circular extension portion connected to said bottom and extending distally downward, said circular extension portion having a substantially planar bottom for said container to stand unassisted on flat surfaces.
Claim 4
Dependent Claim 24 words
The specimen collection container of claim 2 , wherein said circular extension portion further having a hemi-spherical recess for allowing access to said valve.
Claim 5
Dependent Claim 28 words
The specimen collection container of claim 1 , wherein said bottom further comprises an annular protective flap surrounding said valve for reducing splatter when the valve is pierced.
Claim 6
Dependent Claim 56 words
The specimen collection container of claim 1 , wherein said side walls include at least one external protrusion and said lid includes at least one internal protrusion such that when said lid is connected by said internal protrusion to said external protrusion, a permanent and leak-resistant connection is formed between said lid and said side walls.
Claim 7
Dependent Claim 29 words
The specimen collection container of claim 1 , wherein said valve includes a conical inlet for providing audible and tactile confirmation of the opening of said valve when pierced.
Claim 8
Dependent Claim 34 words
The specimen collection container of claim 1 , wherein said side walls and said lid further comprise an array of ribs for gripping said lid during locking of said lid on said side walls.
Claim 9
Dependent Claim 59 words
The specimen collection container of claim 1 , further comprising a test tube having a closed bottom, an open top, cylindrical side walls extending therebetween, and a stopper attached to said open top, said stopper having a piercing member for attaching said test tube to said valve such that the container is in fluid communication with said test tube.
Claim 10
Dependent Claim 43 words
The specimen collection container of claim 1 , wherein said vent of said lid is offset from the center point of said lid, and said lid further includes an air-permeable lid cover disposed thereon, said lid cover allows air flow from said membrane.
