Cleaning tools and associated methods for cleaning lumens of medical devices are provided. An embodiment of the cleaning tool comprises an elongated core, two scrubbers attached to the elongated core, and a wiper attached to the elongated core. The wiper is axially disposed between the two scrubbers. The cleaning tool may be used to clean the lumen prior to decontamination of the lumen.

A cleaning tool with a reservoir comprises an elongated handle attached to one end of a cleaning-head hub and an open cell liquid absorptive material, referred to as a squeeze sponge located within the cleaning-head hub. The cleaning tool has a reservoir for holding fluid within the cleaning-head hub and handle removable interchangeable scrubbing components for cleaning grills and griddles. The sponge holds the fluid and dispenses the cleaning liquid drawn from the reservoir to the heat tolerant liquid permeable material used for scrubbing. A mounting plate liquid barrier layer is disposed at a bottom of the reservoir. A plunger plate is disposed above the squeeze sponge and comprises a perimeter seal fitted to mesh against interior sides of the reservoir. A knob is coupled plunger plate above it. A vertical stabilizer rod is disposed within the interior of the reservoir and fitted to the plunger plate.

A method and apparatus for producing round brushes having bristles clamped between two wire portions of a folded wire, comprising a feed station and a subsequent finishing station, wherein in the feed station a wire is bent between two counter holders, and the feed station comprises a bristle feed device and a rotatable gripper adapted to grip the bent wire and twist it during the feed of bristles to anchor the bristles in the wire. In the finishing station, the twisted wire is held by a stationary gripper and further twisted by the rotatable gripper. The bristles are then cut on their outer side.

An infinity brush has a flaccid belt configured to define a lemniscate. A plurality of work-contacting segments protrude from and are carried by the flaccid belt. A mechanical drive rotates the flaccid belt. Various embodiments of the flaccid belt include a single lemniscate, a plurality of lemniscates, and various simulated lemniscates. In one embodiment, the infinity brush bristle includes non-cylindrical brush bristles with a longitudinal shaft having at least one diameter transition, while other bristles comprise beads of various oval, circular, and cylindrical geometries.

The present invention pertains to a method and apparatus for cleaning soot, creosote, and other materials adhered to the interior walls of a chimney using a mobile cleaning and vacuuming unit. The apparatus is comprised of a pressurized water delivery system, a vacuum system, a chimney cleaning attachment having a plurality of spray nozzles arranged radially about a central axis, and one or more extensions. The required length and corresponding number of extensions are attached to a pressurized water delivery system as needed to access the chimney interior. The chimney cleaning attachment is mechanically affixed to the free end of the extensions and the device is lowered into a chimney. The water delivery system delivers high pressured water to the nozzle abrade the undesirable material within the chimney. A vacuum system positioned near the base of the chimney removes the water and substances that are dislodged during the washing process.

An apparatus for manufacturing round brushes includes motor-driven driven rollers (22, 26) which on twisting of the wire halves urge wire to a rotating gripper (60). The wire material slides along diverters (52, 54).
