ABSTRACT:
An apparatus for transporting and preserving perishable test samples, comprising: a pair of substantially flat leaf members foldably connected to one another; membranes disposed on each of the leaf members over a substantial portion thereof, forming reservoirs; a latent refrigerant disposed in the reservoir; and, at least one strip for gripping and holding the leaf members together to surround and cushion the test sample, and hold the test sample in heat exchanging relationship with the reservoirs, whereby upon activation of the latent refrigerant the test samples may be safely transported and preserved in a chilled environment. The leaf members and the membranes may be flat except for portions corresponding in shape to the test samples, the portions forming a pocket for receiving a test sample. The pocket may be formed by a holding strap disposed over one of the reservoirs. The leaf members may alternatively bear a clip member for holding the test sample.
A method for transporting and preserving perishable test samples, comprising the steps of: providing at least one of a pair of substantially flat leaf members, foldably connected to one another, with an integrally formed reservoir over a substantial portion thereof; filling the reservoir with a latent refrigerant; and, after a perishable test sample has been taken, activating the latent refrigerant; and, surrounding and cushioning the test sample with the reservoir and holding the test sample in heat exchanging relationship therewith, by closing the leaf members together over the test samples, whereby the test sample may be safely transported and preserved in a chilled environment.
