A cleaning apparatus for cleaning of medical machine components of machines such as CPAP machines, nebulizers, PEEP machines, and the like is disclosed herein. The cleaning apparatus comprises a container body. A carousel is configured for placement within the container body. The carousel comprises a support structure. The carousel further comprises a helical ramp attached to the support structure and extending helically from an operative top end of the support structure to an operative bottom end of the support structure along a periphery of the support structure.

The present disclosure is a food injection needle cleaning system and method. The food injection needle cleaning system comprises a cleaning fluid tank coupled to high-pressure pump configured to pump cleaning fluid through at least one inlet, a channel, and at least one outlet of a food injection needle to dislodge and remove debris as well as sanitize the needle. The present disclosure comprises a high-pressure chamber configured to secure the food injection needle and seal around the needle such that fluid enters the needle through an inlet of the high-pressure chamber and exits the needle through a waste line.

A device for cleaning a handle, includes a handle including a gripping surface to be disinfected, an application member for applying a cleaning liquid to the gripping surface, and cleaning liquid supply including at least one reservoir for receiving cleaning liquid and distributing it to the application member. The application member includes at least one buffer reserve arranged in contact with the gripping surface. The device includes a unit for actuating the application member, including a driver configured to move the buffer reserve and/or the gripping surface relatively with respect to one another so as to apply cleaning liquid to substantially the entire gripping surface during this movement.

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.

A system for cleaning heat exchange tubes includes one or more cleaning robots that are assembled with the tubes. Each cleaning robot includes a housing having an opening extending therethrough for receiving one of the heat exchange tubes, a scraper blade extending into the opening of the housing, the scraper blade having an inner scraping edge that opposes the outer surface of one of the tubes, a wheel coupled with the housing for rolling over the outer surface of the tube, and a motor for driving rotation of the wheel to move the cleaning robot over the outer surface of the tube. The system includes a system controller with one or more microprocessors and one or more software programs for monitoring and controlling operation of the cleaning robots.

A method for cleaning a paint spray gun, which comprises a rotating atomization head to apply a coating material while rotating and an outer circumferential tube to cover the exterior of the rotating atomization head, has a cleaning solution application step for applying a cleaning solution to the external face of the outer circumferential tube, and a rotating atomization head rotation step for generating a rotational flow between the rotating atomization head and the outer circumferential tube by rotating the rotating atomization head. The cleaning solution flowing down the external face of the outer circumferential tube applied in the cleaning solution application step penetrates between the rotating atomization head and the outer circumferential tube by way of the rotational flow. Such method uses a small amount of cleaning solution for cleaning external and internal faces of the outer circumferential tube and the external face of a rotating atomization head.
