James Gauger - Highland Park IL, US

International Classification:

B65D 88/22
B65D 37/00

B65D 81/18

US Classification:

383 613, 2065243, 2065244, 383103, 383111

Abstract:

An isolation apparatus for transporting and storing objects or human remains. The apparatus is formed of a flexible, foldable, opaque, generally box-like enclosure fabricated of a fiber reinforced plastic film, and welded together to form a sealed, air-tight and/or liquid-tight enclosure. A gas and liquid sealing zipper is positioned along three of four sides of the enclosure, thereby allowing the apparatus to open in a clamshell or suitcase-like manner, for easy access to the interior of the enclosure. An NBC and/or a CBRN filter can be mounted to the apparatus to allow for release of pressure from within the enclosure. An interior liner made of chemical protective fabric can be placed within the enclosure for additional chemical containment. This apparatus eliminates or significantly reduces the size and number of cracks, crevices and/or other voids into which contaminated materials can enter, for example by positioning, sizing and/or structuring welds to extend completely to an edge of the isolation apparatus, and/or by welding materials together entirely around one or more peripheries.

Abstract:

An isolation apparatus for the transport of a patient who is potentially infectious, who has been subjected to chemical or biological agents or who is threatened by chemical/biological attack. The invention comprises a transparent or semi-transparent, generally tubular enclosure, having two opposite ends. Secured to each of the two opposite ends of this transparent or semi-transparent, tubular enclosure are a pair of end walls. At least one semi-rigid support band extends around a portion of the outer periphery of the generally tubular enclosure. A base mat assembly, comprising at least a first flexible, flat sheet having a top side and a bottom side, is also a part of the invention. The top side of this first flat sheet is secured to the generally tubular enclosure. The bottom side of this sheet is secured to at least one reinforcing strap.
