Abstract

An endoscope reprocessor includes: a filtering tool including: a main body portion provided with a channel connecting a lead-in portion and a lead-out portion; a filter portion provided in the channel; and a first check valve provided in the channel; a processing tank; a tank that stores a disinfecting liquid; a lead-out conduit that guides the fluid led out from the lead-out portion to the processing tank; a second check valve with a distal end connected to the lead-out conduit; a first conduit with a distal end connected to the second check valve and a proximal end connected to the tank; and an injection pump that transfers the disinfecting liquid in the tank from the proximal end toward the distal end of the first conduit.

First claim

What is claimed is:

1 . An endoscope reprocessor comprising:
a filtering tool comprising: a lead-in portion that leads in a fluid; a lead-out portion that leads out the fluid; a main body portion provided with a channel connecting the lead-in portion and the lead-out portion; a filter portion that is provided in the channel and filters the fluid flowing through the channel; and a first check valve that is provided between the filter portion and the lead-out portion in the channel and allows the fluid to pass only in a direction from the filter portion toward the lead-out portion; a processing tank that houses at least one of an endoscope and an endoscope accessory; a tank that stores a cleaning liquid or a disinfecting liquid; a lead-out conduit that is detachably connected to the lead-out portion of the filtering tool and guides the fluid led out from the lead-out portion to the processing tank; a second check valve with a distal end connected to the lead-out conduit, the second check valve allowing the fluid to pass only in a direction from a proximal end toward the distal end; a first conduit with a distal end connected to the second check valve and a proximal end connected to the tank; and an injection pump that transfers the cleaning liquid or the disinfecting liquid in the tank from the proximal end toward the distal end of the first conduit.

2 . The endoscope reprocessor according to claim 1 , further comprising
a third check valve that is provided in a section of the lead-out conduit from a distal end to a part connected with the second check valve and that allows the fluid to pass only in a direction from the lead-out portion toward the processing tank in the lead-out conduit.
