A sample tube is washed by inserting a suction tube from an open end of the sample tube having a closed end, and circulating washing liquid supplied from an upper side of the closed end of the sample tube over an exterior and in an interior of the sample tube to suck and discharge the liquid through the suction tube. The sample tube is washed by providing a holder for holding the sample tube in a manner that the open end of the sample tube having a closed end, the suction tube of which upper end...

A method for cleaning a plurality of drainpipes installed in a movable equipment by causing a flow of a cleaning solution through the drainpipes includes the steps of connecting provisional pipes to the plurality of drainpipes, feeding a cleaning solution into the provisional pipes and the drainpipes, and applying negative pressure suction force to the provisional pipes and the drainpipes to cause a flow of the cleaning solution in the opposite direction to a drain direction in normal use, to th...

An ultrasonic cleaning method for cleaning the interior surfaces of tubes. The method uses an ultrasonic generator and reflector each coupled to opposing ends of the open-ended, fluid-filled tube. Fluid-tight couplings seal the reflector and generator to the tube, preventing leakage of fluid from the interior of the tube. The reflector and generator are operatively connected to actuators, whereby the distance between them can be varied. When the distance is changed, the frequency of the sound wa...

A tip cleaning accessory for enhancement in the utility of rigid endoscopic instruments is hereinafter disclosed. This accessory includes a complimentary tubular member adapted for use with a rigid endoscope. The endoscope contemplated for use with such an accessory includes a handset or handle, a rigid tubular shaft, having a plurality of functional channels adapted for acceptance of at least two fiber optic bundles, the first bundle for illuminating the operative field and a second bundle for ...

Disclosed are systems and methods for removing stubborn contaminants, aluminum fluoride and aluminum chloride in particular, from components of semiconductor-processing equipment. One embodiment forces steam through small holes in a gas distribution plate to remove build up on the interior walls of the holes. A cleaning fixture disposed between the steam source and the gas distribution plate delivers the steam at increased pressures. The gas distribution plate can be immersed in water during cle...

There is a disclosed a cleaning for a medical instrument, including a nozzle main body detachably to a surgical ultrasonic treatment instrument including a channel, and the nozzle main body includes a water supply port opened in a position connected to the channel, when mounted in the surgical ultrasonic treatment instrument.

A permanently mounted tank cleaning apparatus cleans interior surfaces of a bulk milk storage tank using a plurality of cleaning cycles, each cycle characterized by a separate cleaning step. The tank includes a device for dispersing fluid against the interior surfaces of the tank and an outlet proximate its bottom interior surface. A pump is fixedly associated with the dispersing device by a conduit and pumps fluid to the dispersing device through the conduit. A three-way valve assembly is fixed...

A pipeline cleaning and renovating method of the present invention comprises introduction of abrasive particulates by pressurized air through the pipelines to remove the incrustation adhering to the inner surface of the pipelines. Water or other liquids are introduced into the pipelines to generate or increase a moisture content in a flow of the pressurized air. The air flow through the pipelines is controlled to induce a substantially helical flow pattern such that a substantial amount of abras...

The present invention relates to a device and a method for cleaning teat cups (21) in a milking machine. It comprises a teat cup holding rack (1) having a teat cup (21) connected to a milk line (11), teat cup cleaning device (25) with cleaning fluid supply device such as a nozzle (41) and teat cup storing (19', 19"), milk line actuator (9, 53, 55) for retracting the milk line (11) until the teat cup (21) is positioned upside down and in contact with the teat cup storing device (19', 19"); and te...

A connector for use with a lumen device during the cleaning and sterilization of devices is provided. The connector provides fluid communication between a fluid source and the device. In particular, during the cleaning and sterilization cycle, the connection between the connector and the device does not produce occluded areas at the point of connection where the connector is sealably attached to the device.
