Abstract:
A packaging for transporting diagnostic specimens, comprising:a flexible, air tight, liquid impervious inner bladder for receiving a diagnostic specimen, the inner bladder capable of being sealed; and a flexible, air permeable, liquid permeable containment envelope comprising a first end and a second end, the first end further comprising a cavity and the second end further comprising a pocket, wherein the first end may be placed in the pocket of the second end creating a friction fit to seal the containment envelope allowing the diagnostic specimen to be transported and stored in conditions below âˆ’20Â° C. for extended periods of time without risking the integrity of the packaging; wherein the cavity of the containment envelope is smaller than the fully expanded inner bladder creating a pressure differential, the inner bladder being placed in compression inside the cavity of the containment envelope whereby the containment envelope remains dimensionally stable at a maximum intended pressure differential.
