  • Patent number: 8182744
    Abstract: Systems and methods to reduce bioburden on at least a portion of a fluid transfer port include supplying a dose of radiation to the portion in optical communication with at least one source of radiation. In an illustrative example, a medical container, such as a vial or IV bag, receives a dose of ultraviolet (UV) energy substantially at a predetermined region of a fluid transfer site. In some examples, such a sanitization process may precede a fluid transfer operation in which a fluid is transferred into or out of the medical container by passing through the sanitized region. Such fluid transfers may be used in automated or semi-automated pharmaceutical processes, such as drug reconstitution. Various embodiments may further include one or more seal assemblies, each seal assembly having an aperture through which the radiation dose is supplied from the source to a controlled region on the fluid transfer port.
