Abstract

Apparatus for cleansing endoscopes, comprises a holder device, a cylindrical cleaning container, time control means for placing said holder device under timed control, a rotatable mounting for said holder device, said holder device being arranged for directing the barrel of the endoscope to be cleaned towards the interior of said cleaning container, said cleaning container being provided, for a substantial part of its length and around its circumference, with first nozzles which are connectable to a hot water line and which are orientated radially and/or at an angle to the axis of the container, with at least one succeeding circumferential series of second nozzles which are connectable to a pressurized container for containing a disinfecting liquid, and following these, with at least one further circumferential series of third nozzles to which compressed air can be applied. The cleaning container has a controllable return line to said pressurized container and an outlet having a controlled valve. The supply to the nozzles and the operation of the return line and of said outlet of said cleaning container are controllable from a central point by means of selectable programmes.

Claims

1. Apparatus for cleaning endoscopes comprising a container having a first set of nozzles connected to a source of water, a second set of nozzles connected to a source of disinfecting liquid, and a third set of nozzles connected to a source of compressed air, control valves respectively interposed between each source and the related nozzles, a rotatable mount positioned above the container and adapted to suspend the endoscope, a vertically movable support supporting the mount so that on downward movement the suspended endoscope is submerged in whilst on subsequent upward movement the endoscope emerges from the container, motor means respectively for moving the support and rotating the mount, and control means for selectively operating the motors and the valves.

2. Apparatus according to claim 1 wherein a filter and a water softener are connected between said water source and the first set of nozzles.

3. Apparatus according to claim 1, wherein said container includes at its underside an ultrasonic vibrator operable from an ultrasonic generator which is associated therewith and controlled by said control means as part of a cleaning program.

4. Apparatus according to claim 1 in which there is a return line from the container to the water source, the return line having a controllable valve therein, and in which there is an independent return line from the container to the source of disinfecting liquid, said independent return line also having a controllable valve therein.
