Abstract: A forward articulating cleaning and removal apparatus for cleaning a drainage structure. An example apparatus includes a housing to extend into a structure to be cleared and/or removed, through an open end of the structure to be cleared. The example apparatus also includes a distal edge formed on the housing to cut or loosen debris. At least one coil within the housing moves the cut or loosened debris away from the distal edge formed on the housing to a proximal end of the housing. A debris escape opening is formed in the proximal end of the housing. A stem at the proximal end of the housing is provided for connecting to a rotational power source to drive the housing. The example apparatus includes at least one cutting edge on the distal edge of the housing and/or the at least one coil within the housing.

Abstract: A furnace system includes a furnace and a preheater configured to preheat material before it enters the furnace. The system further includes a duct system including a mixing chamber disposed between the furnace and preheater. The duct system further includes an exhaust duct in fluid communication with an exhaust fluid outlet of the furnace and configured to vent fluid exhausted from the furnace. The exhaust duct is in fluid communication with the mixing chamber and configured to redirect a portion of the fluid exhausted from the furnace to the mixing chamber. The duct system further includes a preheater duct in fluid communication with the mixing chamber and a fluid inlet of the preheater and configured to direct fluid from the mixing chamber to the preheater. The system further includes a duct scraper configured for movement within the mixing chamber to move particulates from the mixing chamber into the exhaust duct.

Abstract: A hand-held, collapsible, self-adjusting mechanism, which is an improvement to the Spatula, for removing the remaining contents inside a plurality of containers. The device consists of three attached arms, two lower arms geared around their pivot ends to each other to keep their rotation symmetrical in relation to a drive arm, and pressurized with a double torsion spring to rotate towards said drive arm to apply pressure to a swiveling attachment receiver at the opposite end which makes contact with the inside walls of a container. The drive arm has a foldable crank arm assembly which allows you to quickly rotate and slide the mechanism in and out within a container with one hand while the other hand supports said container thus removing the contents from the walls of the container without difficulty or a mess.

Abstract: A luer cleaner (100) including a generally hollow body (112) having an open first end (104), a closed second end (106), and a longitudinal axis extending therethrough between the first end and the second end. The first end (104) is sized to receive therein a luer connector (190) proximal end and includes a plurality of bristles (134) extending generally toward the longitudinal axis sufficiently to engage the outer surfaces of the luer proximal end disposed therein. The second end comprises a compressible reservoir (166) containing a fluid (168), wherein, when the second end is compressed, the fluid is transmitted from the reservoir toward the first end through passageways to wet the luer proximal end. A method for cleaning luer connectors is also disclosed.

Abstract: A method for cleaning interior surfaces of a header region of a hemodialyzer includes steps of: introducing an insertion device having an end portion and a shaft through a hemodialyzer plug port so that the end portion of the insertion device is within the header region; rotating the shaft at a speed sufficient to generate mechanical stresses for the removal of contaminants from interior surfaces of the header region; removing the insertion device from the header region; and rinsing and flushing away the removed contaminants from the header region. An apparatus and an insertion device for cleaning a header region of a hemodialyzer are disclosed.

Abstract: The present invention provides a reaction chamber cleaning apparatus comprising a chamber, a blade apparatus comprising at least one annular mounting member, at least four scraping blades attached peripherally about the annular mounting member, and a reciprocal movement unit for rotating said scraping blade(s) circumferentially back and forth along the interior surface of said chamber to scrape the interior surface of said chamber; said reaction chamber cleaning apparatus also comprising a vortex unit comprising a generally conical outer shell attached to and extending downwardly from the top plate top plate, and a liquid inlet arranged in relation to the outer shell to tangentially introduce liquid into the outer shell, thereby forming a laminar sheet of fluid on the inner surface of the outer shell; said vortex unit further comprising a baffle and a concentric chamber bounded by the outer surface of the baffle, the inner surface of the outer shell, and the bottom surface of the top plate.
