System and apparatus for evacuation of contaminated fluids from flexible hulled vessels
View Patent ↗A system for collection, containment, and disposal of contaminated fluids includes a flexible hulled containment vessel having at least one resilient deformable wall and a flow directing apparatus with a body that extends into the containment vessel during use, and an exterior portal that extends from the containment vessel in use. The flow directing apparatus provides fluid communication from an interior of the containment vessel while resisting collapse of the deformable wall during removal of contaminated fluid therefrom. A body of the flow directing apparatus includes side wall apertures spaced along a length thereof, sized to accommodate solids expected to be in the contaminated fluids. Bridge structures help resist collapse. A diameter of the body may be larger than a diameter of the exterior portal, which may further resist collapse. The containment vessel may be foldable for transport or storage.
1. A system for collection, containment, and disposal of contaminated fluids, the system comprising:
a flexible hulled containment vessel having at least one resilient deformable wall which forms an interior compartment of the containment vessel, the containment vessel including a port to provide access between the interior compartment and an exterior of the containment vessel;
a coupler positioned about the port that provides detachable but sealing fluid coupling to evacuate a stream of contaminated fluid from within the containment vessel;
a flow directing apparatus having a body having a proximal end, a distal end, a passage extending between the proximal and distal ends, the body having an exterior opening at the proximal end, and at least two apertures sequentially spaced along the body toward the distal end relative to the proximal end with a bridge formed between successive ones of the apertures, the apertures each dimensioned to receive solids found in the contaminated fluids, the body having an outer perimeter sized to be received through the port into the interior compartment of the containment vessel, a portion of the flow directing apparatus sized and configured to detachably sealingly couple to the coupler when at least a portion of the body is positioned through the port into the interior compartment of the containment vessel; and
an exterior portal coupled to the body proximate the proximal end of the body to provide fluid passage therebetween, the exterior portal having a vacuum hose coupler which provides selectively releasable coupling to a sewage vacuum truck hose, wherein the exterior portal has a first diameter and the body has a second diameter, the second diameter greater than the first diameter.

5. The system of claim 1 , further comprising:
a thermally insulating material disposed over at least a portion of the resilient deformable wall of the containment vessel.
6. A system for collection, containment, and disposal of contaminated fluids, the system comprising:
a flexible hulled containment vessel having at least one resilient deformable wall which forms an interior compartment of the containment vessel, the containment vessel including a port to provide access between the interior compartment and an exterior of the containment vessel;
a coupler positioned about the port that provides detachable but sealing fluid coupling means, for evacuating to evacuate a stream of contaminated fluid from within the containment vessel; and
a flow directing apparatus having a body having a proximal end, a distal end, a passage extending between the proximal and distal ends, the body having an exterior opening at the proximal end and an interior opening proximate the distal end, and at least two apertures sequentially spaced along the body toward the distal end relative to the proximal end with a bridge formed between successive ones of the apertures, the apertures each dimensioned to receive solids found in the contaminated fluids, the body having an outer perimeter sized to be received through the port into the interior compartment of the containment vessel, a portion of the flow directing apparatus sized and configured to detachably sealingly couple to the coupler when at least a portion of the body is positioned through the port into the interior compartment of the containment vessel, wherein the interior opening is coincident with a distal most one of the apertures.
7. A system for collection, containment, and disposal of contaminated fluids, the system comprising:
a flexible hulled containment vessel having at least one resilient deformable wall which forms an interior compartment of the containment vessel, the containment vessel including a port to provide access between the interior compartment and an exterior of the containment vessel;
a coupler positioned about the port that provides detachable but sealing fluid coupling to evacuate a stream of contaminated fluid from within the containment vessel;
a flow directing apparatus having a body having a proximal end, a distal end, a passage extending between the proximal and distal ends, the body having an exterior opening at the proximal end, and at least two apertures sequentially spaced along the body toward the distal end relative to the proximal end with a bridge formed between successive ones of the apertures, the apertures each dimensioned to receive solids found in the contaminated fluids, the body having an outer perimeter sized to be received through the port into the interior compartment of the containment vessel, a portion of the flow directing apparatus sized and configured to detachably sealingly couple to the coupler when at least a portion of the body is positioned through the port into the interior compartment of the containment vessel; and
at least one heater element physically and thermally coupled to the resilient deformable wall of the containment vessel.
8. The system of claim 7 , further comprising:
an electrical cable electrically coupled to the at least one heater element.
9. The system of claim 7 , further comprising:
a thermally insulating material disposed over the at least one heater element.
10. The system of claim 1 wherein a length of the body between the proximal and the distal ends is less than 30 inches.
11. A flow directing system for use with a flexible hulled containment vessel from having an interior compartment to receive, contain and dispose of contaminated fluids, the flow directing apparatus comprising:
an exterior portal located exterior to the interior compartment in use, the exterior portal having a vacuum hose coupler sized and configured to provide selectively releasable coupling to a sewage vacuum truck hose; and
a body having a proximal end, a distal end, a passage extending between the proximal and distal ends, the body having an exterior opening at the proximal end, and at least two apertures sequentially spaced along the body toward the distal end relative to the proximal end with at least one bridge that extends between successive ones of the apertures, the apertures each dimensioned to receive solids found in the contaminated fluids, the body having an outer perimeter sized to be received through a port into the interior compartment of the containment vessel in use, the passage of the body fluidly coupled to the exterior portal,
wherein the exterior portal has a first diameter and the body has a second diameter, the second diameter greater than the first diameter.
12. The system of claim 11 wherein the apertures are circumferentially aligned with one another about a principal axis of the body.
