Abstract

Claims (16)

1. A cryogenic storage device, comprising:

a dewar for storing or transporting cryogenic material, the dewar having an inner surface and a first transition area and a second transition area on the inner surface;

a protective barrier positioned within the inner surface of the dewar and configured to prevent contact between cryogenic material stored within the protective barrier and the inner surface of the dewar, the protective barrier having a protective liner that has a first row of one or more tabs that snap into the first transition area and a second row of one or more tabs that snap into the second transition area, the protective liner having a base positioned at a bottom of the protective liner, the base having a plurality of rigid and concentric protrusions to form a shape of the protective liner, the plurality of rigid and concentric protrusions each being shaped in concentric circles; and

an accessory holder positioned within the protective liner and configured to accommodate a plurality of accessories.

2. The cryogenic storage device of claim 1 , wherein the protective barrier has one or more dimples, wherein the accessory holder is configured to snap or fasten to the one or more dimples to prevent accidental removal of the accessory holder.

3. The cryogenic storage device of claim 1 , wherein the first row of the one or more tabs are positioned on a perimeter of the protective liner, wherein the protective liner has a temperature sensor channel on a side of the protective liner and that is configured to guide a temperature sensor lead wire.

4. The cryogenic storage device of claim 3 , wherein the protective liner is a disposable liner.

5. The cryogenic storage device of claim 3 , wherein the temperature sensor channel is configured to protect the temperature sensor lead wire from abrasion when the cryogenic material is loaded into or unloaded out of the protective liner.

6. The cryogenic storage device of claim 3 , wherein the protective liner is collapsible.

7. The cryogenic storage device of claim 3 , wherein the first transition area is positioned between a neck tube and a payload area of the dewar and the second transition area is positioned within the neck tube or a top of the dewar.

8. The cryogenic storage device of claim 1 , wherein the base is configured to interlock with the accessory holder that is configured to accommodate the plurality of accessories.

9. A cryogenic storage device, comprising:

a dewar for storing or transporting cryogenic material, the dewar having an inner surface and a first transition area and a second transition area on the inner surface;

a protective barrier positioned within the inner surface of the dewar and configured to prevent contact between cryogenic material stored within the protective barrier and the inner surface of the dewar, the protective barrier having a protective liner, the protective liner having a base positioned at a bottom of the protective liner, the base having a plurality of rigid and concentric protrusions to form a shape of the protective liner, the plurality of rigid and concentric protrusions each being shaped in concentric circles; and

an accessory holder positioned within the protective liner and configured to accommodate a plurality of accessories.

10. The cryogenic storage device of claim 9 , wherein the protective liner has a temperature sensor channel on a side of the protective liner and that is configured to guide a temperature sensor lead wire.
