A washing tube of the present invention is a washing tube for supplying a washing and disinfecting fluid to an endoscope conduit of an endoscope placed in an endoscope washing and disinfecting apparatus, includes: a tube body, one end of which is connected to fluid supply sections of the endoscope washing and disinfecting apparatus for sending a fluid, a connector section disposed at the other end of the tube body and loosely and detachably fitted to a base of the endoscope conduit, a sealing member that is provided inside the connector section and comes into close contact with the base to keep the base and the connector section connected in a watertight manner, a valve body that moves forward by a liquid sending pressure of the supplied fluid and a biasing member provided inside the connector section for biasing the valve body backward.

Washing tube and endoscope washing and disinfecting apparatus

An endoscope washing and disinfecting apparatus includes: a connecting portion connected to a bending transmitting portion of an endoscope to transmit driving force; a distal end driving portion for transmitting the driving force to the bending transmitting portion through the connecting portion; a fluid supplying unit for supplying gas into an inner space of the endoscope; and a control unit for controlling a pressure detecting portion for detecting pressure in the inner space and the distal end driving portion to provide the bending portion with bending motion, and for determining occurrence or nonoccurrence of water leak in the endoscope by comparing the pressure detected by the pressure detecting portion and a preset threshold.

Endoscope washing and disinfecting apparatus and leak detection method performed by the apparatus

An endoscope cleaning/disinfecting apparatusaccording to the prevent invention includes an apparatus bodyincluding a cleaning tankfor storing an endoscope retaining trayin which an endoscopeis stored, a top coverprovided to the apparatus bodyand caused by a cover body opening/closing mechanism unit to rotationally move between an open-state stop position and a closed-state stop position, a wireless tagprovided to either one of the endoscope retaining trayand the endoscopestored in the endoscope retaining trayand transmitting information for identifying the type of the endoscope, a wireless receiver unitprovided to the apparatus bodyand receiving the information of the wireless tag, and a control unitprovided to the apparatus bodyand determining whether or not to cause an opening movement of the top coveron the basis of the information obtained by the wireless receiver unitto thereby control the rotational movement by the cover body opening/closing mechanism unit. Accordingly, cleaning and disinfection of the used endoscope can be hygienically and effectively performed.

Endoscope cleaning/disinfecting apparatus

An apparatus for washing and disinfecting an endoscope is provided. First and second chemicals and dilution water, which dilutes the chemicals to be used for disinfecting the endoscope, are charged into a tank. The tank includes a first portion, a second portion having an area of base smaller than that of the first portion, a first sensor detecting that the dilution water is charged into the first portion up to a first level, a second sensor detecting that the first chemical is charged into the second portion up to a second level, and a third sensor detecting that the second chemical is charged into the second portion up to a third level. A unit measures a first volume of the first chemical based on a result of the second sensor and measures a second volume of the second chemical based on results of the third sensor and the second sensor.

Apparatus for washing and disinfecting endoscope by using diluted chemicals

An endoscope washer disinfector washes and disinfects an endoscope with a mouth ring communicating with an endoscope duct. The washer disinfector comprises a washing disinfecting bath; a nozzle arranged with the bath, loaded into the mouth ring, and formed to supply fluid to the duct via the mouth ring; a tray on which the endoscope is mounted. In this washer disinfector, a bilateral positioning member positions the endoscope and the tray so that the mouth ring of the endoscope mounted on the tray is located at a given position on the tray; and a trilateral positioning member positions the washing disinfecting bath, the tray, and the endoscope so that, when the tray is loaded into the washing disinfecting bath, the mouth ring of the endoscope positioned at the given position on the tray by the bilateral positioning member is positioned at a position that is across is from the nozzle.
