ず洗浄，消毒していた。[Prior Art] As is well known, in addition to light guides and image guides that mainly consist of optical fiber bundles, there are many types of conduit-forming devices that are named according to their purpose, such as air supply, water supply, suction, etc. The endoscope, which has a built-in channel and is currently highly praised for its functionality and effectiveness as a medical device, can be used to observe, test, and inspect the inside of the body cavity by inserting its insertion part into the body cavity. Since it is used not only for diagnosis but also for treatment, from a hygienic standpoint, not only the outside surface but also the inside of the various pipes must be cleaned and disinfected each time it is used. was.

施の兆をみせはじめてきた。 The method of cleaning and disinfecting was to immerse the control unit in a cleaning and disinfecting solution, which was considered to be the simplest and most effective method. Since it is extremely difficult to completely clean and disinfect the inside of each conduit formed by each long and thin channel that reaches the insertion site through the tube, it is necessary to directly pressurize cleaning and disinfecting liquid into each conduit one by one. This method was also used, but it was troublesome and involved a lot of time loss.
A valve body with a leak hole is removed from the body of a cylindrical valve body such as a switching valve for water supply or an on-off valve for suction, and is fixed to a bridge between the upper end openings of both cylindrical valve body bodies, which is referred to as a plug body with a communication passage, etc. Using adapters for cleaning and disinfecting various pipes, various pipes are communicated with both cylindrical valve casing bodies, and all pipes inside can be simultaneously cleaned with cleaning and disinfecting liquid, etc., which is press-fitted from one place. , methods of disinfection have been proposed and are beginning to show signs of implementation.

For cleaning and disinfection, a connecting short pipe section is attached and fixed to a bridge between the tops of the bottomed cylindrical valve housing bodies of air and water supply switching valves, suction on-off valves, etc. The inner circumferential surface of the connecting short pipe part in the adapter for the cylindrical valve casing is connected to the tapered connecting beak part of the gas pumping device for pumping gas into each pipe line connected to the cylindrical valve housing body. ．． It is characterized by a tapered opening that becomes larger toward the opening end that can be fitted and fixed in an airtight manner.

効率良く、しかも確実に行なわれることとなる。[Function] Cleaning of various ducts in the endoscope according to the present invention,
Because the disinfection adapter has the above-mentioned configuration, it is difficult to operate it when cleaning and disinfecting the inside of each conduit built into the endoscope that is used for air supply, water supply, and suction. Remove the valve bodies with leak holes of air and water supply switching valves, suction on-off valves, etc. that are installed close to the valve body, and bend the cylindrical pipe part appropriately to the upper end opening of each cylindrical valve housing body. Adjust the spacing and install the connecting short pipe parts, and attach and fix the cleaning and disinfection adapter of this invention to the bridge between both upper end openings, and connect various pipes for air supply, water supply, suction, etc. As with conventional endoscopes of this type, a device for pumping cleaning and disinfecting liquid was attached to the forceps introduction port of the forceps insertion conduit to which the suction conduit was connected. By force-feeding a cleaning liquid or a disinfectant, various pipes for different purposes can be simultaneously cleaned and disinfected, or cleaned after disinfection, etc., efficiently and reliably.

と払拭排出せしめることとなる。 After cleaning or disinfecting, remove the cleaning/disinfecting adapter from the upper opening of one cylindrical valve housing body, and insert the tapered taper of the gas pump into the tapered opening of the removed cleaning/disinfecting adapter. If you insert and attach the articulated pressure-feeding beak tube and operate the gas-feeder to force-feed gas, the contact area will be widened by both tapers, and water and airtightness will be maintained well. The gas pressure-fed into the other cylindrical valve housing body is forced to flow at a substantially uniform flow rate through a conduit of approximately the same diameter connected to the other cylindrical valve housing body, without leaking;
All of the cleaning liquid and disinfectant that have adhered and accumulated within this conduit are wiped and discharged out of the conduit, that is, out of the endoscope.

Reattach it to the main body of the casing, and do the same as above.
This is used to wipe away cleaning liquid or disinfectant that has accumulated in the cylindrical valve housing body and the conduit connected to it, which often has a different diameter than the above-mentioned conduit. .

出されることとなる。 Therefore, as shown in FIGS. 5 and 6, the forceps inlet 9 is equipped with a forceps plug for keeping water and airtight, and one end of the cleaning/disinfecting adapter B according to the present invention is provided. Separately remove the parts from the air supply/water supply switching valve 10 or the suction on/off valve 40, and insert them into the tapered opening 105 of the connecting short pipe part 101 at the removed end as a gas pressure feeder. If you use a syringe that has aspirated clean gas and insert and attach the tapered beak tube of the syringe, which corresponds to the tapered connecting beak tube, water,
The possibility of maintaining airtightness increases, and if clean gas is sent under pressure to the air supply pipe 20 and water supply pipe 30 of each valve 10, 40, and the suction pipe 50 of a separate system, Unlike the case where all the pipes 20, 30, and 50 are forced to be fed at the same time, the number of outlets is reduced, so the pumping pressure is higher and the flow rate is faster.
The cleaning liquid or disinfectant liquid that had been stuck and retained inside the pipe 20, 30, and 50 is completely wiped away.
