Methods, packaging and apparatus for collection of biological samples
Methods, apparatus and compositions are disclosed for collection and transport of biological samples for testing and/or evaluation by a clinical laboratory. In particular, the disclosure relates to the self-collection of such samples by subjects providing the samples. Self-collection is necessary in some situations e.g. where a subject's religion prohibits being touched by a non-family member and subjects at great distance from medical facilities.
1. A packaging for a biological material comprising:
a flexible receptacle comprising a primary reclosable sealing means, the flexible receptacle containing a preservative and the biological material suspended or dissolved in the preservative, the preservative in direct contact with an inside surface of the flexible receptacle, the primary reclosable sealing means preventing flow of the preservative from the flexible receptacle when in a closed position;
a rigid reclosable support containing the flexible receptacle, wherein said support comprises one or more additional sealing means for said receptacle; and
wherein the one or more additional sealing means creates one or more pinch points in the flexible receptacle adjacent the primary reclosable sealing means, the one or more additional sealing means preventing flow of the preservative from the flexible receptacle.
2. The flexible receptacle of claim 1 wherein said primary reclosable sealing means comprises one of a press seal, a zipper seal, a screw seal, and a snap seal.
3. The packaging of claim 1 , wherein the one or more pinch points are configured to prevent failure of the primary reclosable sealing means of said flexible receptacle.
4. The packaging of claim 1 , wherein said preservative is in liquid or solid form, and wherein said one or more pinch points is located between a substantial portion of said preservative and said primary reclosable sealing means.
5. The packaging of claim 4 , wherein failure of the primary reclosable sealing means of said flexible receptacle is prevented by limiting forces from said preservative applied to said primary reclosable sealing means by blocking a portion of said preservative from interacting with said recloseable sealing means at said one or more pinch points.
6. The packaging of claim 1 further comprising a second reclosable support, said second reclosable support enclosing said reclosable support.
7. The packaging of claim 6 , wherein said second reclosable support further comprises provision for enclosing at least one of additional materials and supplies that are at least one of necessary and useful in the collection of said biological material.
8. A method of packaging a biological material, the method comprising:
collecting the biological material on a collection device;
inserting a preservative into a flexible receptacle, the flexible receptacle including a primary reclosable sealing means;
placing the collecting device in the flexible receptacle such that the biological material is suspended or dissolved in the preservative, and wherein an inside surface of the flexible receptacle is in direct contact with the preservative;
closing the primary reclosable sealing means such that the primary reclosable sealing means prevents flow of the preservative from the flexible receptacle;
placing the flexible receptacle in a rigid reclosable support, the rigid reclosable support including one or more additional sealing means;
closing the rigid reclosable support such that the primary reclosable sealing means of the flexible receptacle is located outside the rigid reclosable support; and
creating a pinch point in the flexible receptacle through the one or more additional sealing means of the rigid reclosable support, the one or more additional sealing means preventing flow of the preservative from the flexible receptacle.
9. The method of claims 8 , the method including the step of inserting the preservative as a liquid or solid into the flexible receptacle before closing the primary reclosable sealing means.
10. The method of claim 8 , wherein the pinch point in the flexible receptacle is adjacent the primary reclosable sealing means.
11. A packaging for a clinical sample comprising a suspension or solution of a biological material in a fluid, the packaging comprising:
a flexible receptacle comprising a primary reclosable sealing means, wherein the fluid of the clinical sample is in direct contact with an inside surface of the flexible receptacle, and wherein the primary reclosable sealing means prevents flow of the fluid from the flexible receptacle when in a closed position;
a rigid reclosable support containing the flexible receptacle, wherein said support comprises one or more additional sealing means for said receptacle; and
wherein the one or more additional sealing means creates one or more pinch points in the flexible receptacle adjacent the primary reclosable sealing means, the one or more additional sealing means preventing flow of the fluid from the flexible receptacle.
