  • Hazardous material handling system and method
    Patent number: 7758560
    Abstract: A method and system for handling hazardous materials contained in a vial includes an isolation enclosure having an opening selectively sealable about the vial, a bag body portion, and a cap portion. A latching extraction element is attached to the cap portion and has a preceding engaging member to secure the vial to the isolation enclosure, an extraction member to be inserted into the vial and remove material therefrom, and a primary engaging member to secure the vial to the extraction member. A valve is mounted outside the isolation enclosure and controls the flow of fluid from the vial. An adaptor having a reseal member permits flow when coupled to the valve and restricts flow when uncoupled from the valve. Once uncoupled, the adaptor is removably associated with a second valve located remotely from the isolation enclosure, allowing fluid to pass into the second valve.
