A cleaning device is configured to access and remove fluid from and dry a moat region defined by a hub of a medical connector, thereby minimizing the potential for bacterial growth in the hub. The cleaning device takes the form of an absorbent block which can be inserted into the moat by extending about a central male fitting and into a gap between the male fitting and the inner wall of a female hub of the medical connector. In a preferred embodiment of the invention, the block takes the form of a tubular cylinder particularly configured for use on ENFit medical connectors wherein the absorptive feature of the cleaning device can be employed alone or in combination with another cleaning tool used to first remove any existing dried and caked solution in the hub before removing residual cleaning fluid from the moat.

A pipe scraper (1) comprising: a housing (2) comprising a bore (21) having a centre axis and an open end (24) that allows access to the bore (21), the bore (21) being shaped to receive into its open end (24) at least a portion of each of two pipes (19, 20) of an assembly of two concentric pipes (19, 20), wherein the assembly of two concentric pipes (19, 20) comprises a pipe (19) having a smaller diameter, and a pipe (20) having a larger diameter, and the end of the pipe (20) having the larger diameter is separated from the end of the pipe (19) having the smaller diameter by a distance along the central axis of the assembly; a first scraper tool assembly 9, 10, 11, 16) secured to the housing (2), configured to urge a first scraper tool (9) radially inwards, and positioned at a first radial distance from the centre axis of the bore (21), and at a first axial distance from the open end (24) of the bore (21); a second scraper tool assembly (13, 14, 15, 17) secured to the housing (2), configured to urge a second scraper tool (13) radially inwards, and positioned at a second radial distance from the centre axis of the bore (21), and at a second axial distance from the open end (24) of the bore (21), wherein the first radial distance is smaller than the second radial distance, and the first axial distance is larger than the second axial distance; and a transmission means (4) to allow torque to be delivered to the housing (2) to cause rotation of the housing (2) about the centre axis of the bore (21); wherein the first scraper tool (9) is configured so that rotation of the housing (2) will cause the first scraper tool (9) to scrape portions of a pipe (20) that are in contact with the first scraper tool (9), and wherein the second scraper tool (13) is configured so that rotation of the housing (2) will cause the second scraper tool (13) to scrape portions of a pipe (19) that are in contact with the second scraper tool (13).

Methods and apparatus are provided for washing pipette tips, including the inside and outside of the pipette tip. Pipette wash devices comprise a main body comprising a wash chamber, a liquid channel, a gas channel, and a nozzle cavity, and a nozzle for providing a washing mist is positioned in the nozzle cavity and fluidically connected with the liquid channel and the gas channel. Methods of washing a pipette tip include inserting a pipette tip in a wash chamber; spraying a mist on an outside surface of the pipette tip; and blowing pressurized air or inert gas on the outside surface of the pipette tip, thereby washing and drying the pipette. Methods of washing a pipette tip also include passing one or more series of liquid slugs separated by gaseous gaps through the inside of the pipette tip.

The present disclosure relates generally to the field of medical devices and medical device accessories. In particular, the present disclosure relates to a tool or accessory for cleaning a medical device. For example, the tool or accessory may clean a fluid delivery lumen of an endoscopic submucosal dissection (ESD) knife. The tool or accessory may include a housing with a first portion of an elongate member secured within a first portion of the housing and a second portion of the elongate member extending into a chamber of the housing.

A cleaning tool for insertion device includes a first fluid supply conduit, a second fluid supply conduit, a first cap component, and a second cap component, wherein a first discharge port and a third discharge port are disposed at positions where a discharging direction of fluid discharged from the first discharge port and a discharging direction of fluid discharged from the third discharge port are parallel or coaxial to each other in a vertical direction of a distal end portion of an insertion device, and a second discharge port and a fourth discharge port are disposed at positions where a discharging direction of fluid discharged from the second discharge port and a discharging direction of fluid discharged from the fourth discharge port are parallel or coaxial to each other in a lateral direction of the distal end portion of the insertion device.

A thread cleaner comprising an elongated body with a drive end and an open end, with an abrasive section, a scraper section, and a brush section at the open end, the scraper section intermediate the abrasive section and the brush section, the scraper section, and brush sections oriented to apply radial scraping and brushing force to an elongated workpiece positioned in alignment with the thread cleaner's central axis, and the abrasive section oriented to apply abrasive force perpendicular to the thread cleaner's central axis to a surface workpiece.

A faucet cleaning assembly includes a pouch which has an inner layer and an outer layer. The inner layer is comprised of a fluid impermeable material defining an interior of the pouch thereby facilitating the interior of the pouch to contain an acidic solution. The pouch is positionable around a faucet thereby facilitating the acidic solution to dissolve mineral deposits on the faucet. A band is integrated into the pouch and a drawstring is integrated into the band. The band is collapsible when the drawstring is tightened for retaining the pouch on the faucet. A lock is slidably disposed on the drawstring to retain the drawstring in a tightened condition for retaining the band around the faucet.

A method of using an ultrasonic system includes positioning at least one component to a ultrasonic system, the ultrasonic system including: an ultrasonic device, comprising a plurality of ultrasonic transducers coupled to a flexible body; a power supply coupled to the ultrasonic device; a fluid vessel configured to supply fluid to the at least one component; and a waste vessel configured to collect the fluid supplied to the ultrasonic device from the fluid vessel. The method includes applying, via the power supply, a current to a plurality of ultrasonic transducers to dislodge a plurality of contaminants from the at least one component. The method includes flushing, via fluid from the fluid vessel, the plurality of contaminants dislodged from the at least one component.
