  • Container for storing and shipping needle cartridges
    Patent number: 6472675
    Abstract: A container for storing and transporting needle cartridges containing radioactive materials used for medical procedures is disclosed. Such needle cartridges may include a radioactive shielding material which contains a portion of the radioactivity emitted by the radioactive material. The container of the present invention has an upper portion and a lower portion, and at least one of the portions includes a radiation shielding material, such as lead, steel or other appropriate shielding materials. Needle cartridges containing radioactive material are placed within the container for storage and shipping. The container secures the needle cartridges against lateral movement within the container to protect them from breakage or release of the radioactive materials contained in the needle cartridges. The radiation shielding material of the lower portion of the container may cooperate with the radiation shielding material of the device to container more of the emitted radiation that is contained by the device alone.
