This device is equipped with a passageway for air/water supply, suction, and forceps that communicates with the channel of the insertion section. Needs to be cleaned and disinfected.

Conventionally, this fiberscope cleaning and disinfecting device has a cleaning and disinfecting tank that can accommodate the fiberscope, and while stirring the cleaning and disinfecting solution stored in this cleaning and disinfecting solution tank, it also stirs the cleaning and disinfecting solution stored in the cleaning and disinfecting solution tank and cleans each passage of the fiberscope in the solution tank. Also known is a fiberscope that circulates a cleaning and disinfecting solution so that the inside and outside of the insertion section of the fiberscope can be cleaned and disinfected all at once.

(Means for solving the problem) However, in the case of the conventional washing and disinfecting device mentioned above,
Cleaning and disinfection is performed with the fiberscope placed horizontally, which not only requires a large cleaning area, but also complicates the connecting structure and circulation path for the cleaning disinfectant to the fiberscope insertion section and forceps opening, making the connection work difficult. There were problems in that it was time-consuming and the entire device became large and expensive.

In addition, a large amount (approx.
There were problems such as it being uneconomical because it was necessary for the

The present invention was developed in view of these conventional problems.The device has a simple structure, is relatively easy to use, and can be effectively used with a small amount of cleaning and disinfecting liquid (approximately 200 c.c. to 500 c.c.). It is an object of the present invention to provide a cleaning and disinfecting device for a fiberscope that can be cleaned and disinfected and can be installed even in a narrow place.

(Means for Solving the Problems) The technical means of the present invention for achieving the above objects will be explained with reference to FIG. 1 showing an embodiment. The tip of the operating section 2 of the fiberscope 1 is removably inserted and supported on the upper opening edge, and the fiberscope 1
The insertion part 3 of the pump 11 is immersed in the cleaning disinfectant liquid in the vertical pipe 9, and the pipe 12 on the suction port 11a side of the pump 11 is connected to the lower end of the vertical pipe 9 via the on-off valve 10, and the discharge of the pump 11 is This device is characterized in that the pipe 13 on the outlet 11b side is connected and communicated with the forceps port 7 of the fiberscope 1.

(Function) According to the present invention having the above configuration, when the on-off valve 10 is opened and the pump 11 is driven, the vertical pipe 9
The cleaning and disinfecting solution inside is led to the suction port 11a of the pump 11 through the valve 10, and then
from the outlet 11b of the fiberscope 1 through the piping 13 to the forceps port 7 of the fiberscope 1, from the forceps port 7, through the suction/forceps passage of the insertion section 3, and from the tip of the insertion section 3 to the vertical tube 9. This cycle is repeated and circulated. Then, the inside of the insertion section 3 is cleaned and disinfected.

Moreover, when using it, it can be installed without taking up much space by simply fixing and supporting the vertically long vertical tube 9, for example, along the support of a stand or a desk, and it can also be easily moved. Furthermore, the fiberscope 1 can be easily installed by simply inserting and locking the tip of the operating section 2 into the upper end opening of the vertical tube 9, and the vertical tube 9 is large enough to accommodate the insertion section 3 of the fiberscope 1. Therefore, only a relatively small amount of cleaning and disinfecting solution is needed for one cleaning and disinfection, and cleaning and disinfection can be carried out efficiently and economically.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a medical fiberscope, and as is well known, the distal end 2a of the operating section 2 is formed into a tapered shape. Part 3
has been extended. An optical fiber 4 is inserted into the tube of the insertion section 3, and an air/water supply passage 5 and a suction/forceps passage 6 are formed respectively, and the lower ends of these passages 5 and 6 are connected to the insertion section. It is opened at the lower end of 3. 7 is the operation part 2
The suction/forceps passage 6 is communicated with a forceps port provided in the holder.

The device of the present invention for cleaning and disinfecting the fiberscope 1 configured as described above is equipped with a long vertical cleaning and disinfecting solution storage tube 9 made of a straight tube made of transparent synthetic resin or glass with open upper and lower ends. A female thread 9a is formed at the lower end opening of the tube 9.
A male threaded portion 10 provided at the upper end of the on-off valve 10
a are screwed together in a fluid-tight manner. This opening/closing valve 10 is a lock-type valve that is opened and closed by a lock 10c provided in a valve housing 10b, and the outlet side of the valve 10 and the electric pump 11
A flexible first pipe 12 such as a hose is removably connected between the suction ports 11a. Furthermore,
The discharge port 11b of the electric pump 11, the forceps port 7 of the fiberscope 1, and both ends of a flexible second pipe 13 such as a hose are connected to each other in a detachable manner.

In the above configuration, the length of the vertical tube 9 is determined by the length of the insertion portion 3 of the fiberscope 1 inserted into the vertical tube 9.
The inner diameter is set to such an extent that the intermediate portion of the tapered tip 2a of the operating section 2 is fitted and locked, and when the fiberscope 1 is inserted into the vertical tube 9. The circumferential surface of the intermediate portion of the tapered tip portion 2a is supported by the upper opening edge of the vertical tube 9, and the insertion portion 3 is attached in a suspended state within the vertical tube 9.

When cleaning and disinfecting the fiberscope 1, the vertical tube 9 is fixedly supported in an upright position at an appropriate height on the support 14a using a stand 14 or the like, and the pump is placed at an appropriate place on the floor or the like. 11 is installed, and first and second pipes are installed between the suction port 11a of the pump 11 and the valve 10 provided at the lower end of the vertical pipe 9, and between the discharge port 11b of the pump 11 and the forceps port 7 of the fiberscope 1, respectively. 12 and 13 and further inject the cleaning disinfectant into the vertical tube 9 up to the vicinity of the upper end, then insert the tapered tip 2a of the operating section 2 of the fiberscope 1 into the upper opening edge of the vertical tube 9. By inserting and supporting the insertion portion 3 into the cleaning and disinfecting solution, a circulation path for the cleaning and disinfecting solution contained in the vertical tube 9 is formed.

Next, when the valve 10 is opened and the pump 11 is driven, the cleaning disinfectant in the vertical pipe 9 flows into the forceps port 7 of the fiberscope 1 through the pipes 12 and 13, and into the suction/forceps passage 6 of the insertion section 3. After flowing through and cleaning and disinfecting the inside of the passage 6, the cleaning and disinfecting solution is returned from the tip of the insertion section 3 to the vertical tube 9, thereby cleaning and disinfecting the inside and outside of the insertion section 3.

In the above embodiment, the valve 10 is attached to the lower end of the vertical pipe 9, but it may be provided on the first pipe 12 side.
