PATENT OF THE WEEK– CRYOGENIC STORAGE BAG
The Cryogenic Storage Bag was invented by Philip H. Coelho on December 6, 2018 bearing patent number US20180343852A1.
Cryogenic storage systems have been used in the art to preserve various biological specimens including but not limited to cells, blood, and living tissue at low temperatures for sustained periods. When biological specimens, and in particular blood products are stored in these cryogenic storage systems it is common to store them in plastic storage bags/cryogenic freezing bags.
A cryogenic storage bag for preserving various biological specimens at low temperatures for sustained periods. The storage bag comprises a plurality of storage compartments and a plurality of frangible tabs. At least two of the plurality of frangible tabs connect each of the plurality of storage compartments to an adjacent storage compartment. Each of the plurality of frangible tabs includes at least one notch and a narrowest portion located equidistant from at least two adjacent storage compartments. The at least one notch connects to walls of the at least two adjacent storage compartments utilizing a joining portion of each of the plurality of frangible tabs. The plurality of frangible tabs enables separation of the plurality of storage compartments from one another at cryogenic temperatures while retaining an effective hermetic integrity to each of the plurality of storage compartments.
