  • STORAGE SYSTEM AND METHOD FOR STORING AND TRANSPORTING MEDICAMENT
    Publication number: 20230172808
    Abstract: A storage system for storing a drug includes a container, at least one passive cooling system, and an active cooling system. The container includes an interior volume to accommodate at least one drug. The at least one passive cooling system is disposed within the container and includes a phase change material. The active cooling system is operably coupled with the container and, when in an operational mode, maintains a desired temperature within the interior volume of the container.
