  • Patent number: 10588500
    Abstract: An endoscope reprocessing tool includes: a connection portion configured to be connected with a fluid outlet provided on a bottom face of a reprocessing basin of an endoscope reprocessor; a direction changing portion configured to change a flow direction of fluid discharged from the fluid outlet from a direction against a gravity direction to a direction crossing the gravity direction; a discharge portion configured to discharge the fluid direction-changed by the direction changing portion in the direction crossing the gravity direction; and a positioning portion configured to position a distal end portion of an endoscope so that the discharge portion and a recess portion provided on the distal end portion face each other.

  • Publication number: 20110005556
    Abstract: A cleaning/disinfecting tube allows an opening portion provided in an object to be cleaned accommodated in a cleaning tank of an endoscope cleaning/disinfecting apparatus to communicate with a liquid delivery connector which is provided in the endoscope cleaning/disinfecting apparatus and through which a liquid is supplied. The cleaning/disinfecting tube includes a tube connector section to be connected to the opening portion and a holding portion that engages with the object to be cleaned with a gap therebetween and constrains the movement of the tube connector section in a direction away from the opening portion when the tube connector section is connected to the opening portion.
