Abstract
A protection system is provided for the transfer of toxic liquid from a bulk container through a first conduit to a connector for a delivery device such as a dosage syringe. A second conduit connects the connector to a waste receptacle. The first and second conduits penetrate the closed end of a flexible barrier bag. The bag is initially retracted from the bulk container to allow manipulation of the bulk container. The bag is subsequently extended over and sealed around the bulk container and waste receptacle to protect the health care provider during liquid transfer to the deliver device.
Claims12
A protection system adopted for use with a container from which a hazardous liquid can be removed, said system comprising:
- conduit means for being connected to, and extending from, said container to define a flow path for said liquid from said container to a discharge location exterior of the container;
- and
- a flexible barrier that is impervious to said liquid and that is penetrated by, and sealed to, said conduit means for accommodating (1) an initial arrangement in a retracted orientation permitting access to, and manipulation of, at least a portion of said conduit means and container, and (2) a subsequent arrangement, in an extended orientation enveloping said portion of said conduit means and the connected container.
A protection system adopted for use with a container from which a hazardous liquid can be removed, said system comprising:
- connecting means for being connected to said container to establish fluid communication between the exterior of the container and the liquid inside the container;
- a conduit extending from said connecting means to define a flow path for said liquid from said connecting means to a discharge location exterior of the container;
- and
- a flexible barrier penetrated by said conduit, said barrier being sealed about the periphery of said conduit at the penetration and being impervious to said liquid, said barrier accommodating an initial arrangement in a retracted orientation permitting access to, and manipulation of, at least a portion of said connecting means and container, and said barrier accommodating a subsequent arrangement in an extended orientation for defining an enclosure around said portion of said connecting means and the connected container.
