Abstract

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.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 117 words
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.
Claim 2
Dependent Claim 117 words
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.
Claim 3
Dependent Claim 47 words
The protection system in accordance with claim 1 said conduit means includes a first connecting means for being connected to said container, a first conduit extending from said first connecting means, and a second connecting means on the said first conduit for being connected to a syringe.
Claim 4
Dependent Claim 40 words
The protection system in accordance with claim 1 in which said flexible barrier comprises thermoplastic material having a generally tubular configuration that is closed at one end sealed about said conduit means and that is open at the other end.
Claim 5
Dependent Claim 28 words
The protection system in accordance with claim 3 further including a releasable sealing means at the open end of said tubular configuration for sealing closed the open end.
Claim 6
Dependent Claim 48 words
The protection system in accordance with claim 1 in which said conduit means includes a first conduit; said system further includes a second conduit connected at one end to said first conduit; and said system further includes a receptacle connected to said second conduit in fluid communication therewith.
Claim 7
Dependent Claim 30 words
The protection system in accordance with claim 1 further including a receptacle in fluid communication with said conduit means, said receptacle being integral with said conduit means and flexible barrier.
Claim 8
Dependent Claim 54 words
The protection system in accordance with claim 6 in which said flexible barrier comprises thermoplastic film having a generally tubular configuration and said receptacle is carried on an exterior surface of the tubular configuration when said barrier is arranged in said extended orientation enveloping said portion of said conduit means and the connected container.
Claim 9
Dependent Claim 47 words
The protection system in accordance with claim 6 in which said receptacle is disposed relative to said barrier for being located within, and enclosed by, said barrier when said barrier is arranged in said extended orientation enveloping said portion of said conduit means and the connected container.
Claim 10
Dependent Claim 66 words
The protection system in accordance with claim 1 in which said conduit means includes a connecting means for being connected to said container, a flexible conduit connected to said connecting means, and a distal end terminating in a discharge location exterior of the container; and said system further includes a one-way, non-return valve in said flexible conduit to prevent flow of liquid back into said container.
Claim 11
Dependent Claim 150 words
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.
Claim 12
Dependent Claim 150 words
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.
Claim 13
Dependent Claim 37 words
The protection system in accordance with claim 10 in which said connecting means includes a hollow spike adapted to penetrate a seal on said container and includes a clip for holding said hollow spike and container together.
Claim 14
Dependent Claim 26 words
The protection system in accordance with claim 10 further including a discharge valve on the distal end of said conduit for accommodating connection to a syringe.
