Freeze-free medicinal transport carriers
In some embodiments, a medicinal carrier device includes: one or more sections of thermal insulation positioned to form an internal space with an adjacent first side region and an adjacent second side region; a first panel including a first phase change material positioned within the first side region of the internal space, the first side region of a size and shape to firmly contain an integral number of portable cold packs in thermal contact with the first panel; and a second panel including a second phase change material positioned within the second side region of the internal space, the second side region of a size and shape to firmly contain an integral number of portable cold packs in thermal contact with the second panel.
1. A medicinal carrier device, comprising:
one or more sections of thermal insulation positioned to form an internal space of a volume and a size and shape to hold medicinals; and
at least one thermally conductive barrier fixed within the internal space to form an interior medicinal storage region on a first side of the at least one thermally conductive barrier and one or more external portable cold pack storage regions on a second side of the thermally conductive barrier, the at least one thermally conductive barrier formed from a solid material including phase change material microencapsulated within a thermally-conductive material,
wherein the at least one thermally conductive barrier has a heat capacity, volume and thermal conductivity sufficient to cool the volume of the internal space from an ambient temperature to between 2° C. and 10° C. without falling below 0.5° C. in less than 2 hours from a time point when all of the one or more external portable cold pack storage regions are filled with one or more portable cold packs of a temperature less than −10° C., and to maintain the volume of the internal space to between 0.5° C. and 10° C. for at least 30 hours from the time point; and
wherein the medical carrier device includes an opening between each of the one or more external portable cold pack storage regions and the interior medicinal storage region for removal and insertion of the one or more portable cold packs during use of the device.
2. The medicinal carrier device of claim 1 , wherein the phase change material microencapsulated within the thermally-conductive material comprises:
phase change material having a melting temperature of 6° C.
3. The medicinal carrier device of claim 1 , wherein the one or more portable cold packs equivalent to the volume of the one or more external portable cold pack storage regions comprises:
an integral number of cold packs of a standard size and shape for medicinal transport.
4. The medicinal carrier device of claim 1 , further comprising:
an insert for the medicinal carrier device, the insert of a size and shape to secure the position of the at least one thermally conductive barrier relative to the medicinal storage region.
5. The medicinal carrier device of claim 1 , wherein the one or more sections of thermal insulation form a rectangular structure, and the carrier includes a removable lid.
6. The medicinal carrier device of claim 1 , wherein the one or more sections of thermal insulation comprise:
insulated walls.
7. The medicinal carrier device of claim 1 , wherein the one or more external portable cold pack storage regions are of a size and shape to hold 0.6 L one or more portable cold packs.
8. The medicinal carrier device of claim 1 , wherein the one or more external portable cold pack storage regions are of a size and shape to hold 0.4 L one or more portable cold packs.
9. The medicinal carrier device of claim 1 , further comprising:
an exterior shell surrounding the one or more sections of thermal insulation.
