Description

  The present invention relates to an endoscope cleaning machine that automatically cleans an endoscope. Specifically, the endoscope can be easily loaded into a cleaning tank, and the burden on an operator who performs the endoscope cleaning operation is reduced. The present invention relates to an endoscope cleaning machine that can be greatly reduced.

As is well known, an endoscope is inserted into a living body such as a human body and used for diagnosis and treatment of organs, collection of specimens, and the like.
As is well known, an endoscope basically includes an insertion portion to be inserted into the human body, an operation portion for operating the endoscope such as operation of the insertion portion and air supply / water supply, an air supply source and suction. A connector (LG (Light Guide) connector) connected to a pump or the like, and a universal cord (supply hose) connecting the connector, the operation unit, and the insertion unit are configured.

An endoscope is used repeatedly in common with a plurality of patients. Therefore, after use, it is necessary to perform thorough hygiene management and thoroughly clean each time it is used in order to completely prevent infection of bacteria through the endoscope.
For this reason, various endoscope cleaning machines for automatically cleaning an endoscope have been put into practical use.

As a typical configuration of an endoscope cleaning machine, an endoscope having a cleaning tank and a long tubular cleaning tube communicating with the cleaning tank as shown in Patent Document 1 and Patent Document 2 Mirror washing machines are known.
In this endoscope cleaning machine, the insertion section of a thin and long endoscope is stored in a cleaning tube, and the operation section of the endoscope, connector (connector section), and universal cord (universal cord section) are used as a cleaning tank. The endoscope is cleaned, for example, by circulating a cleaning solution or a disinfecting solution through a path including a cleaning tank and a cleaning tube (or disinfecting the disinfecting solution only).

In addition, as another configuration of the endoscope cleaning machine, as shown in Patent Document 3, it does not have a cleaning tube that accommodates the insertion portion of the endoscope, and the operation portion, the connector, the insertion portion, In addition, an endoscope cleaner having a configuration in which a universal cord is accommodated to perform cleaning is known.
In this endoscope cleaning machine, as shown in Patent Document 3, the insertion portion of the endoscope and the universal cord are accommodated in a cleaning tank in a state of being wound in an arc shape or a spiral shape. The endoscope is cleaned by circulating a cleaning solution and a disinfecting solution through the path including the tank and a path including the cleaning tube (or only the immersion of the disinfecting solution).

  However, these conventional endoscope cleaners have the problem that it takes time and effort to load (set) the endoscope.

In an endoscope cleaning machine having a cleaning tube that accommodates an insertion portion of an endoscope, as shown in Patent Literature 1 and Patent Literature 2, a long insertion portion is accommodated in a small space to reduce the size of the apparatus. In order to achieve this, the washing tube is often helical. However, it takes time and effort to insert the insertion portion into the spiral cleaning tube, and workability is poor.
In addition, an endoscope cleaning machine that does not have a cleaning tube but also stores an endoscope insertion portion in a cleaning tank and performs cleaning takes time and effort to wind the insertion portion and the universal cord. That is, since both are long tubular objects, it is necessary to perform winding while taking a so-called curl, but both the insertion portion and the universal cord have a certain amount of stiffness, so The work of winding while taking is heavy and takes time and effort.

  In addition, both of them need to continue to have the heaviest operating part and connector until the end of the set.

In an endoscope cleaning machine having a cleaning tube, it is usually a procedure to store the operation unit and the connector in the cleaning tank after the insertion portion of the endoscope is first stored in the cleaning tube. And you need to have a connector to the end.
In endoscope cleaning, there are internal forceps channels (forceps tubes) for inserting forceps and air / water channels (air / water tubes) for air and water for camera cleaning. It is necessary to clean the inside of each channel of the endoscope. For this purpose, a port for connecting each channel of the endoscope and a supply means for the cleaning liquid of the endoscope cleaning machine, etc., in the cleaning tank of the endoscope cleaning machine, in order to flow the cleaning liquid etc. inside the channel. (Connecting means) is provided. Here, the forceps hole connected to the port of the endoscope washing machine, the mouthpiece of the suction / air supply / water supply (connector between the endoscope, the vacuum pump, the water supply source, and the air supply source) Located on the connector. Therefore, in order to suitably connect the endoscope cleaning machine to the port, the insertion portion or the like is wound so that the operation portion and the connector are positioned upward in a state where the endoscope is accommodated in the cleaning tank. After all, it is necessary to have a heavy operating part and connector to the end.

  An object of the present invention is to solve the above-mentioned problems of the prior art, and to greatly reduce the burden on the operator who performs the cleaning, thereby enabling the endoscope to be set quickly and easily. It is to provide a mirror cleaning air.

  In order to achieve the above object, an endoscope cleaning machine according to the present invention is an endoscope cleaning machine for cleaning an endoscope, a cleaning tank for storing the endoscope to be cleaned, and a lid of the cleaning tank The endoscope cleaning machine is characterized in that it has a body, the cleaning tank is long, and the bottom surface is inclined in the longitudinal direction.

  In such an endoscope cleaning machine of the present invention, the lid opens and closes the cleaning tank by swinging around a fulcrum, and the fulcrum is provided on the lower bottom side of the cleaning tank. It is preferable that positioning means for the endoscope is provided in the cleaning tank on the upper side of the bottom surface of the cleaning tank, and further, operating means is provided on the upper side of the bottom surface of the cleaning tank. Moreover, it is preferable that the lid body has a region inclined in the same direction as the bottom surface of the cleaning tank when closed, on the side facing the bottom surface of the cleaning tank, and the lid body is transparent. Preferably, the cleaning tank accommodates and cleans one endoscope, and a plurality of the cleaning tanks are arranged in a direction perpendicular to the longitudinal direction of the cleaning tank. It is preferable.

According to the endoscope cleaning machine of the present invention which is long and has a cleaning tank whose bottom surface is inclined, it is possible to easily and quickly set an endoscope without placing a heavy burden on the operator.
When carrying an endoscope, it is often the case that the insertion part or universal cord is folded in half (or zigzag-folded) with the operation part and connector in one hand and the bending part such as the insertion part in the other. .
Therefore, according to the endoscope cleaning machine of the present invention having a long cleaning tank, it can be quickly and easily stored in the cleaning tank without being wound around the insertion portion or the like. A scope can be set. In addition, since the bottom surface of the washing tank is inclined, the endoscope can be inserted into the washing tank by dropping it using gravity, so that it can be quickly and easily inserted into the washing tank properly with less force. A scope can be set. In particular, if the operation is performed from the upper side of the inclined bottom surface and the operation unit and the connector are mounted on the upper side, the insertion unit and the like are inserted into the cleaning tank so as to drop the weight. Since an operation unit and a connector that are present may be placed on the bottom surface on the front side of the cleaning tank, the endoscope can be set in the cleaning tank very quickly and easily.

  Hereinafter, the endoscope washing machine of the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.

FIG. 1 shows a schematic diagram of an example of an endoscope cleaner according to the present invention. 1A is a perspective view, and FIG. 1B is a side view. FIG. 2 shows a schematic top view of the endoscope cleaning machine (a lid 20 to be described later is omitted).
An endoscope cleaning machine 10 (hereinafter referred to as a cleaning machine 10) shown in FIG. 1 is an apparatus that automatically cleans an endoscope 50. The cleaning machine 10 includes two cleaning tanks (hereinafter referred to as a cleaning tank 14 collectively), which are a first cleaning tank 14a and a second cleaning tank 14b, as cleaning tanks that house the endoscope 50 and perform cleaning. The two endoscopes 50 can be cleaned simultaneously and asynchronously (independently).

As will be described in detail later, as shown in FIG. 6, the cleaning machine 10 has three tanks, a cleaning liquid tank 100, a disinfecting liquid tank 102, and an alcohol tank 104. Further, the cleaning machine 10 includes a cleaning liquid pump 106, a disinfecting liquid pump 108, an alcohol pump 110, and the like. In other words, the cleaning machine 10 has two cleaning tanks, a first cleaning tank 14a and a second cleaning tank 14b, and is a device that can clean two endoscopes 50 simultaneously and asynchronously. A tank for storing the processing liquid and a pump for supplying the processing liquid are shared by the two cleaning tanks 14.
In addition, a piping system as shown in FIG. 6 is formed in the cleaning machine 10 in order to clean the endoscope with a cleaning liquid, a disinfecting liquid, or the like.
These will be described in detail later.

  In the cleaning machine 10, the first cleaning tank 14a and the second cleaning tank 14b accommodate the endoscope 50, and are cleaned with the cleaning liquid (cleaning process), rinsed with tap water (rinsing process after cleaning), disinfecting liquid. The endoscope 50 is cleaned by performing four steps of disinfection (disinfection step) by rinsing and rinsing with tap water (rinsing step after disinfection).

The endoscope cleaning machine of the present invention may be configured to accommodate a plurality of endoscopes 50 such as two in one cleaning tank, and may be capable of simultaneously cleaning a plurality of endoscopes. When a plurality of endoscopes 50 are accommodated in one cleaning tank, the endoscopes 50 may overlap each other and the cleaning performance may be deteriorated. Therefore, it is preferable that the endoscope cleaning machine of the present invention has a configuration in which one endoscope is accommodated in one cleaning tank for cleaning.
Moreover, although the washing machine 10 of the example of illustration has the two washing tanks 14, this invention is not limited to this, You may have only one washing tank, Or 3 or more washing | cleaning It may have a tank 14. Furthermore, in the cleaning machine of the present invention, the arrangement direction of the cleaning tanks 14 is not limited to the short direction of the illustrated example, and a plurality of cleaning tanks 14 may be arranged in the longitudinal direction.

  In the illustrated latent image machine 10, the first cleaning tank 14 a and the second cleaning tank 14 b have exactly the same configuration, so the same members are denoted by the same reference numerals, and the following description will be given as the cleaning tank 14. .

  As described above, the cleaning tank 14 (the first cleaning tank 14 a and the second cleaning tank 14 b) accommodates and cleans the endoscope 50, and the upper surface is opened and closed by the lid body 20.

In the cleaning machine 10 of the present invention, as shown in FIG. 1, the cleaning tank 14 has a long shape (planar (upper surface) shape).
In this cleaning machine 10, the endoscope 50 usually has an insertion portion 52 and a universal cord 54 folded in half (in the case of a long endoscope, it is folded in a folded manner) as shown in FIG. The washing tank 14 is placed on the bottom surface (floor surface) 22 so as to accommodate one endoscope 50. As shown in FIG. , Inclined in the longitudinal direction of the cleaning tank 14.
In FIG. 1 and FIG. 2, although omitted to clearly show the configuration of the present invention, each channel of the endoscope 50 such as a forceps channel and an air / water supply channel (its channel) A port for connecting a base and a connecting portion), an introduction port for introducing a treatment liquid such as cleaning water into the cleaning tank 14, and the like are provided. These will be described in detail later.

Moreover, in the washing machine 10, the cover body 20 opens and closes the washing tank 14 (the upper surface) by rotating around the fulcrum 24 as shown in FIG. 1 (B).
Here, as a preferable configuration, the cleaning machine 10 of the illustrated example is provided with a fulcrum (rotating shaft) 24 for opening and closing the lid 20 on the lower side of the inclined bottom surface 22. That is, in the cleaning machine 10, the lid body 20 is rotated so that the upper end of the inclined bottom surface 22 moves up and down to open and close the cleaning tank 14. Further, an operation panel 26 for operating the cleaning machine 10, an endoscope cleaning start button 28, a foot pedal 30 for opening and closing the lid 20 (a pedal 30a for the first cleaning tank 14a and a second cleaning tank 14b). The operation means used for regular cleaning in the cleaning machine 10 such as the foot pedal 30b) is also the upper (upper end) side of the bottom surface 22 of the cleaning tank 14 (preferably near the end of the upper side of the cleaning machine 10, and (Or end face on the upper side).
That is, as a preferred embodiment, the cleaning machine 10 is on the upper side of the inclined bottom surface 22 of the cleaning tank 14 and is the side (front surface) for opening and closing the lid 20 and performing each operation of cleaning the endoscope 50.

  In the present invention, the upper side of the longitudinal center of the bottom surface 22 is the upper side, and the lower side of the center is the lower side.

The endoscope cleaning machine of the present invention is not limited to such a front side bottom surface being the upper part, and the cleaning tank may be configured such that the front side (operation side) bottom surface is the lower part. Good.
Further, the opening and closing of the lid is not limited to being performed in the longitudinal direction of the cleaning tank, and may be a term for opening and closing the lid in the short direction of the cleaning tank. In this case, the end side in the short direction may be used as a side (front surface) for performing various operations.
Further, the lid is not limited to a configuration that rotates around a fulcrum and opens and closes, and may be a sliding lid (shutter). In this case, when the shutter opens and closes in the longitudinal direction of the cleaning tank, it is preferable that the shutter opens from the upper side of the bottom surface of the cleaning tank. Similarly, this side is the side where various operations are performed. (Front surface) is preferable.

  The cleaning machine 10 of the present invention has a configuration in which the cleaning tank 14 is long and the bottom surface is inclined in the longitudinal direction. The endoscope 50 can be easily and quickly accommodated in a predetermined position of the cleaning tank 14.

As described above, an endoscope cleaning machine having a cleaning tube that accommodates the insertion portion (internal insertion portion) 52 of the endoscope 50 as shown in Patent Document 1 and Patent Document 2 is inserted into this cleaning tube. It takes time and effort to insert the portion 52, and as shown in Patent Document 3, the insertion portion 52 of the endoscope 50 and the universal cord (supply cord) 54 are wound without having a washing tube. In the endoscope cleaning machine accommodated in the cleaning tank, it takes time and effort to wind the insertion portion and the like. Further, in both cases, the operator needs to have a heavy operating portion 56 and a connector (LG (Light Guide) connector) 58 to the end.
That is, in the conventional endoscope cleaning machine, it takes time and effort to set the endoscope at a predetermined position such as a cleaning tank, and the burden on the operator is large.

Here, as described above, normally, when the endoscope 50 is carried, the insertion portion 52 and the universal cord 54 are folded in two (long) so that the endoscope 50 does not come into contact with the floor surface or the like. In the case of an endoscope, it is folded), and the operation part 56 and the connector 58 are held in one hand, and the insertion part 52 and the universal cord 54 are bent (or the vicinity thereof). , Often carry an endoscope.
Therefore, according to the cleaning machine 10 of the present invention having the long cleaning tank 14, like the conventional endoscope cleaning machine, the insertion part 52 of the endoscope 50 or the like can be wound or spirally cleaned. The endoscope 50 can be quickly and easily set in the cleaning tank 14 while the endoscope 50 is being carried around without performing troublesome operations such as insertion of the endoscope. In addition, since the bottom surface 22 of the cleaning tank 14 is inclined, the endoscope 50 can be inserted into the cleaning tank 14 from the side of the folded end by using gravity. And the endoscope 50 can be appropriately set in the cleaning tank 14 with a small force. Furthermore, although the cleaning tank 14 is long, the horizontal distance is shortened because the bottom surface 22 is inclined. Therefore, even if the operator is small and the hand is short, the endoscope 50 can be set easily.
In particular, like the cleaning machine 10 in the illustrated example, the upper side of the inclined bottom surface 22 is set as the front surface, and the operation is performed from this side, and the operation unit 56 and the connector 58 are mounted on the upper side. If the configuration is such that the endoscope 50 is set, the insertion portion 52 and the universal cord 54 are inserted into the cleaning tank 14 so as to drop, and the heavy operation portion 56 and connector 58 are placed on the bottom surface 22 on the near side. Therefore, the endoscope 50 can be set in the cleaning tank 14 very quickly and easily.

In addition, by having the long cleaning tank 14, if the cleaning tank 14 is arranged in a direction orthogonal to the longitudinal direction (hereinafter referred to as the width direction), the apparatus does not become so large.
That is, according to the present invention, it is not necessary to house a plurality of endoscopes 50 in one washing tank (that is, one endoscope 50 is washed with one washing tank 14), and the plurality of endoscopes 50 The washing machine 10 capable of simultaneously processing the endoscope 50 can be easily realized in a small space (floor area), and a large number of endoscopes 50 can be efficiently washed even in a narrow room.

Furthermore, as for the washing machine 10 of the example of illustration, as a preferable aspect, the front surface of the washing machine 10 is concave as shown in FIG.
As described above, the cleaning machine 10 sets the endoscope 50 so that the endoscope 50 is dropped into the long cleaning tank 14 from the front to the back with the endoscope 50 folded. When performing such operations, humans often bend their knees unconsciously. Therefore, like the cleaning machine 10 in the illustrated example, by making the front surface concave, it is possible to suitably prevent the front surface of the cleaning machine 10 from interfering with the operation of bending the knee, with better operability. The endoscope 50 can be set in the cleaning machine 10.
The concave shape of the front surface of the washing machine 10 is not particularly limited, but according to the study of the present inventor, the amount of the dent (the most concave surface from the foremost plane when assuming no dent) A concave shape in which the distance to (position) is about 40 to 60 cm and the height from the installation surface of the apparatus to the most recessed position is about 40 to 70 cm is preferable. Is preferred. In the cleaning machine 10 of the present invention, since the front surface is concave in the vertical direction, a suitable effect can be obtained, so the horizontal direction may be the same surface.

In the present invention, the inclination of the bottom surface 22 of the cleaning tank 14 is not particularly limited, but according to the study by the present inventors, the vertical height between the upper end portion and the lower end portion of the bottom surface 22 in the longitudinal direction is not limited. The difference is preferably about 20 to 40 cm, and particularly preferably about 29 to 35 cm.
By setting the inclination of the bottom surface 22 of the cleaning tank 14 as described above, the effect of the inclination of the bottom surface 22 is expressed more suitably, and the endoscope 50 is set in the cleaning tank 14. Can be performed more easily and quickly.

In the present invention, the shape of the bottom surface 22 of the cleaning tank 14 is not limited to a flat plate, but the bottom surface 22 of the cleaning tank 14 is inclined in one direction, and preferably has a height difference in the vertical direction. It has only to be inclined.
For example, as schematically shown in FIG. 3 (A), a plurality of flat plates having different angles may be provided, such as areas having different inclinations (angles with respect to the horizontal direction).
Further, the bottom surface 22 is not limited to a planar shape, and may be a curved surface having an upwardly convex shape (outcurl) as schematically shown in FIG. 3B, or schematically shown in FIG. As shown specifically, an upwardly concave (incurl) curved surface may be used. In addition, when the bottom surface 22 is a curved surface, the curvature may be constant over the entire area in the tilt direction, or may have regions with different curvatures, or may have a wavy shape. The bottom surface 22 may be a combination of a flat surface and a curved surface.
Further, the bottom surface 22 of the cleaning tank 14 is, for example, as shown schematically in FIG. 3D, a return portion (pit) for improving drainage from the cleaning tank 14 in the vicinity of the lower end. ). In this case, the bottom surface 22 of the cleaning tank 14 is substantially up to the lowest portion z that forms the return portion.

As described above, in the cleaning machine of the present invention, the endoscope 50 is set (stored in a predetermined position) in the cleaning tank 14 so as to be placed on the bottom surface 22.
Here, on the bottom surface 22 of the cleaning tank 14 (the bottom surface 22 is preferable, but the inner surface of the cleaning tank 14 is also acceptable), the operation unit 56 of the endoscope 50, the connector 58, the universal cord 54, the insertion unit 52, and the like. It is preferable to have positioning means for positioning. In particular, as described above, in the present invention, the operation portion 56 and the connector 58 of the endoscope 50 are positioned on the upper side of the bottom surface 22, and the insertion portion 52 and the universal cord 54 are dropped into the cleaning tank 14. Since it is preferable to set the endoscope 50, it is preferable to have positioning means for the operation portion 56 of the endoscope 50 and the connector 58 on the bottom 22 on the upper side (same as above).

In the cleaning layer 14 in the illustrated example, the operation unit 56 that engages with the operation unit 56 of the endoscope 50 so as to stand on the bottom surface 22 on the upper side and falls due to the inclination of the bottom surface 22 is viewed from below. The engaging member 34 (34a and 34b) that supports and positions, and the engaging member that similarly engages with the connector 58 and supports and positions the connector 58 to be dropped due to the inclination of the bottom surface 22 from below. 36 (36a and 36b). Therefore, the endoscope 50 is positioned at the predetermined position of the cleaning machine 10, that is, the cleaning tank 14 (bottom surface 22), with the operation portion 56 positioned by the engaging member 34 and the connector 58 positioned by the engaging member 36. .
By having such an endoscope positioning means, the endoscope 50 can be appropriately set in the cleaning machine 10 (cleaning tank 14) more easily and quickly.

Note that various known means can be used as positioning means for each part of the endoscope 50 such as an operation part or a connector provided on the bottom surface 22 or the like.
As an example, a concave portion that loosely fits or houses a predetermined portion of the operation portion or the like, an engagement member that is fixedly engaged with each portion of the endoscope 50, and is about to fall along the inclination of the bottom surface 22 as in the illustrated example. A hook, an engaging member, and the like that are engaged with the operating portion 56 and the like to be supported from below are exemplified.

The positioning means may also serve as a fixing means for each part of the endoscope 50, or may have a fixing means for fixing each part of the endoscope 50 separately from the positioning means.
In addition, in order to smoothly accommodate the insertion portion 52 and the universal cord 54 in the cleaning tank 14, it is preferable that the bottom surface 22 has no protrusions other than these positioning means and fixing means.

As described above, in the cleaning machine 10 of the present invention, the cleaning tank 14 has a long shape (planar shape).
In the present invention, there is no particular limitation on the size x in the width direction (short direction) and the size y in the longitudinal direction of the cleaning tank 14 (the region in which the endoscope 50 is accommodated) (see FIG. 2). Therefore, the size of the cleaning tank 14 may be appropriately determined according to the type of the endoscope 60 to be cleaned. Here, in the present invention, the long washing tank 14 preferably has a size x in the width direction of 40 cm or less, particularly about 20 to 40 cm, and a ratio of the size in the longitudinal direction to the width direction (longitudinal direction / The ratio of the width direction (y / x) is 2 or more, particularly 4 or more.
According to the study by the present inventors, since the cleaning tank 14 has the long shape as described above, most of the endoscopes 50 currently used can be easily and easily cleaned. Can be accommodated, and even when a plurality of cleaning tanks 14 are provided, it is possible to suitably prevent useless enlargement of the cleaning machine 10.

In the endoscope cleaning machine of the present invention, the shape of the cleaning tank is not limited to a rectangle as shown in the illustrated example, and may be, for example, a trapezoid as shown in FIG. The shape as shown in 4 (B) (so-called tall shape) may be used.
In the present invention, various shapes can be used as the shape of the cleaning tank. As an example, the size of the cleaning tank can be changed depending on the shape of the cleaning tank as shown by the dotted line in FIG. Assuming a minimum rectangle inscribed in, the long side direction of this rectangle is the longitudinal direction of the cleaning tank, and the length of the long side of this rectangle is the size y in the longitudinal direction of the cleaning tank, the short side of this rectangle What is necessary is just to let length be the size x of the width direction of a washing tank.

Further, the height of the cleaning tank 14 (height of the upper end (basket) of the cleaning tank 14) is not particularly limited, but is preferably about 60 to 100 cm, particularly about 70 to 90 cm.
According to the study by the present inventors, when the height of the cleaning tank 14 is in the above range, when the various operations are performed with the longitudinal direction of the cleaning tank 14 as the front surface, even a small operator, The endoscope 50 can be set in the cleaning machine 10 without difficulty.

In the cleaning machine 10 of the present invention, the shape of the lid 20 of the cleaning tank 14 is not particularly limited, and the cleaning tank 14 (inside the tank) can be closed, preferably substantially airtight (particularly preferably airtight). If it exists, the thing of various structures and shapes according to the shape of the washing tank 14 can be utilized.
In the cleaning machine 10 shown in the drawing, the lid 20 is opened and closed by a foot pedal 30 provided on the front side of the cleaning machine 10 as in various endoscope cleaning machines. The lid 20 can be opened and closed by the foot pedal 30 by using known means used in various endoscope washing machines.

Here, in the present invention, the lid body 20 is not a simple plate, but is the same as the bottom surface 22 when closed on the side facing the bottom surface 22 of the cleaning tank 14 (hereinafter referred to as the bottom surface of the lid body 20). It is preferable to have a region inclined in the direction.
The region inclined in the same direction as the bottom surface 22 formed on the lower surface of the lid body 20 is formed so as to be parallel or substantially parallel to the bottom surface 22 when the lid body 20 is closed, as shown in FIG. It is preferable to do this.

As a matter of course, considering the running cost of the cleaning machine 10 and environmental pollution, the amount of processing liquid such as cleaning liquid, disinfecting liquid, and rinsing water used for cleaning the endoscope 50 is small. Is preferred.
In order to perform the cleaning properly, it is necessary to immerse the entire endoscope 50 in the processing liquid. Here, as described above, in the cleaning machine 10 of the present invention, the bottom surface 22 of the cleaning tank 14 is inclined, and the endoscope 50 is accommodated in the cleaning tank 14 so as to be placed on the bottom surface 22. . Therefore, in order to immerse all the endoscopes 50 in the processing liquid, it is necessary to fill the cleaning tank 14 with the processing liquid up to the highest position of the endoscope 50 accommodated in the cleaning tank 14.

However, in many regions in the cleaning tank 14 (the region where the endoscope 50 is accommodated), the endoscope 50 does not exist in the upper space, particularly in the lower region, that is, this space is a useless space. In this sense, the treatment liquid in this region is an unnecessary treatment liquid. In particular, a large wasted space exists in the upper part of the lower region of the inclined bottom surface 22.
In the cleaning machine 10 of the illustrated example, the cleaning liquid is prepared using tap water and a stock solution of the cleaning liquid for each cleaning, and is discarded every time, so that a large amount of unnecessary cleaning liquid is used. turn into. In addition, the disinfecting solution is usually reused a predetermined number of times, but in recent years, the disinfecting solution is discarded every time for the purpose of more advanced hygiene management and more reliable infection prevention. In many cases, it is desired to clean the endoscope 50. In this case, too, a large amount of unnecessary disinfectant is used.

On the other hand, as shown in FIG. 1, the bottom surface of the lid body 20 is inclined in the same direction as the bottom surface 22, that is, the bottom surface side of the lid body 20 is in the same direction as the bottom surface 22. By having a shape like an inclined convex shape (having a convex portion), it is possible to fill a useless space where the endoscope 50 above the cleaning tank 14 does not exist with the lid 20.
Therefore, by having such a configuration, it is possible to clean the endoscope 50 with a small amount of processing liquid, and the cleaning machine 10 having excellent running cost and environmental performance that does not use unnecessary processing liquid. realizable. In particular, as in the illustrated example, it is preferable that the lid 20 has a region parallel or substantially parallel to the bottom surface 22 on the lower surface, so that the lid 20 can more preferably fill a useless space.

It is preferable that a region of the lower surface of the lid 20 that is inclined in the same direction as the bottom surface 22 is provided at least in a region on the lower side of the inclined bottom surface 22, and in particular, the endoscope 50 is located at a predetermined position of the cleaning tank 14. In the set state, it is preferable to have an inclined area of the lower surface of the lid 20 above the area where only the insertion portion of the endoscope 50 and the universal cord exist.
Further, in order to suitably reduce the amount of the processing liquid, the inclined region of the lower surface of the lid body 20 is within a range that does not come into contact with the endoscope 50 set in the cleaning tank 14, as much as possible. Of course, the lower surface is preferably close to the bottom surface 22. Furthermore, in order to suitably reduce the amount of the processing liquid, it is of course preferable that the region inclined in the same direction as the bottom surface 22 of the lower surface of the lid 20 is preferably as large as possible in the width direction. In the width direction of 14 (inside thereof), it is preferable that the convex portion, which is a region inclined in the same direction as the bottom surface, be sized to fit or loosely fit into the inner wall surface of the cleaning tank 14.

The lid 20 can be formed of various materials as long as it has sufficient resistance to a treatment liquid such as a cleaning liquid or a disinfecting liquid. Here, it is preferable that the lid 20 is transparent and allows the operator to visually observe the inside of the cleaning tank 14 with the lid of the cleaning tank 14 covered.
As will be described later, the cleaning machine 10 can perform a water leak test for confirming that each channel of the endoscope 50 is free of damage such as holes. Here, as will be described later, the preferable timing of the water leakage inspection is, for example, setting the endoscope 50 to be cleaned in the cleaning machine 10 (cleaning tank 14) and supplying tap water for performing the cleaning process to the cleaning tank 14. At the time of introduction, the water leakage test is performed by pressurizing each channel of the endoscope 50 from the outside with air and confirming whether bubbles are generated from the distal end of the insertion portion. Therefore, by making the lid 20 transparent, the endoscope 50 can be set for cleaning, and a water leak test can be performed while the lid 20 is closed. Moreover, the state of the endoscope 50 can be confirmed even during cleaning by making the lid 30 transparent.

The washing machine 10 of the present invention preferably has an IC tag reader (IC tag reading means). In particular, when the endoscope 50 is positioned on the bottom surface 22 of the cleaning tank 14 and the operation unit is positioned above the bottom surface 22 and the endoscope 50 is set in the cleaning tank 14. Is preferred.
In recent years, in order to manage the cleaning history and inspection history of the endoscope 50, an IC tag in which the identification information of the endoscope 50 is recorded may be attached to the endoscope 50. As described above, when the IC tag is attached to the endoscope 50, the IC tag is often attached to the operation unit 56. However, when the cleaning tank 14 has positioning means for the endoscope 50, the operation unit 56, that is, The IC tag is also located in a predetermined area in the cleaning tank 14 (cleaning machine 10).
Therefore, by providing an IC tag reader in the cleaning machine 10 according to the position of the positioning means of the operation unit 56 of the endoscope 50, it is particularly necessary to hold the IC tag of the endoscope 50 over the IC tag reader. Exchange information.

In the present invention, the attachment position of the IC tag reader is not particularly limited, and may be set as appropriate according to the position of the positioning means of the operation unit 56 of the endoscope 50, but is preferably attached to the lid body 20. .

It is preferable to set the endoscope 50. Therefore, by providing the IC tag reader on the lid 20 of the cleaning tank 14, the information of the IC tag attached to the endoscope 50 can be read reliably. Recently, it is conceivable that the operator also carries the IC tag and manages the information of the operator who cleaned the endoscope 50. However, by providing an IC tag reader on the lid 20, the endoscope 50 is provided. At the time of cleaning operation, the operator's IC tag can be brought close to the IC tag reader, and the operator's IC tag can be read without performing operations such as holding the IC tag.

In the cleaning machine 10, the endoscope 50 is basically cleaned in the order of a cleaning process using a cleaning liquid → a rinsing process → a disinfection process using a disinfecting liquid → a rinsing process.
Hereinafter, an example of the operation of cleaning the endoscope 50 by the cleaning machine 10 will be described. In the following description, the first cleaning tank 14a is also representative, but the endoscope can also be cleaned in the same manner in the second cleaning tank 14b. Further, in the following description, all the valves are closed except for the valve described as open in the description of each process in each process, even if not specifically described, and other than the pump described as drive, All are stopped.

First, the operating portion 56 is positioned by the engaging means 34 and the connector 56 is positioned by the engaging means 36, and the endoscope 50 is set at a predetermined position in the first cleaning tank 14a by the operator. The forceps rise channel of the endoscope 50 is connected to the port 124a, the forceps channel to the forceps port 126a, the air / water supply channel to the air / water supply port 128a, and the suction tube channel to the suction port 130a. .
In addition, what is necessary is just to perform the connection with each channel and each channel of the endoscope 50 by the well-known means currently performed with the endoscope washing machine using a connector, a connecting pipe, etc. FIG.

When the setting of the endoscope 50 is completed and an instruction to start cleaning is input, the cleaning machine 10 first performs a cleaning process.
First, the pressure reducing valve 168 and the first valve 170 of the water supply line 164 and the valve 180a connected to the water supply port 136a are opened, the first cleaning is performed from the water supply port 136a via the water supply line 163a. A predetermined amount of tap water is introduced into the tank 14a (introduction of tap water).
When a predetermined amount of tap water is introduced, the valve 176a connected to the cleaning liquid port 132a is opened, the cleaning liquid pump 106 is driven, and the cleaning liquid is supplied from the cleaning liquid tank 100 to the cleaning liquid port 132a. A predetermined amount of cleaning liquid is supplied (introducing cleaning liquid).

In addition, in the washing machine 10, after the tap water is introduced in the cleaning process (between the tap water introduction and the cleaning liquid introduction), a water leakage detection process described later may be performed as necessary.
Moreover, when not implementing a water leak detection process, you may perform introduction of a tap water, and introduction | transduction of a washing | cleaning liquid in parallel.

When a predetermined amount of tap water and cleaning liquid are introduced into the first cleaning tank 14a, the valve 162a is opened to drive the circulation pump 182, and for example, the valve 150a and forceps port 126a connected to the forceps raising port 124a. The valve 152a connected to the air supply / water supply port 128a and the valve 156a connected to the suction port 130a are sequentially opened for a predetermined time one by one. The valve opening time may be the same or different at each port.
Accordingly, the cleaning liquid in the first cleaning tank 14a is circulated through each channel of the endoscope 50, and each channel of the endoscope 50 is sequentially cleaned with the cleaning water (channel cleaning).

When the channel cleaning is completed, the valve 180a corresponding to the water supply port 136a is opened and the circulation pump 182 is driven.
Accordingly, the cleaning liquid in the first cleaning tank 14a is circulated outside the endoscope 50, and the outside of the endoscope 50 is cleaned with cleaning water (external flowing water cleaning).

When the external running water cleaning is performed for a predetermined time, the valve 190a and the valve 192 are opened, the drain pump 118 is driven, and the cleaning liquid in the first cleaning tank 14 is drained (cleaning drain).
When all the cleaning liquid in the first cleaning tank 14 is drained, the valve 190a and the valve 192 remain open, and the valve 160a is opened to drive the second air pump 116 and connected to the forceps raising port 124a. The valve 150a, the valve 152a connected to the forceps port 126a, the valve 154a connected to the air / water supply port 128a, and the valve 156a connected to the suction port 130a are sequentially opened one by one.
As a result, air is sequentially fed from the forceps raising port 124a, the forceps port 126a, the air / water feeding port 128a, and the suction port 130a to each channel of the endoscope 50, and the cleaning liquid remaining in the channel is endoscopically viewed. Drain from the mirror (clean air supply).

The cleaning process is thus completed, and then a rinsing process after cleaning is performed.
The rinsing process after cleaning is basically performed in the same manner as the cleaning process except that the cleaning liquid is not introduced into the first cleaning tank 14.
That is, first, the pressure reducing valve 168, the first valve 170, and the valve 180a are opened to introduce a predetermined amount of tap water into the first cleaning tank 14a (introduction of tap water).
After introducing a predetermined amount of tap water into the first cleaning tank 14a, the valve 162a is opened, the circulation pump 182 is driven, and the valve 150a, the valve 152a, the valve 154a, and the valve 156a are one by one. In the same manner as channel cleaning, the channels of the endoscope 50 are sequentially rinsed with tap water, and then rinsed with tap water. Then, the valve 180a is opened and the circulation pump 182 is driven to In the same manner as in running water cleaning, external running water rinsing is performed by rinsing the exterior of the endoscope 50 with tap water.
When the external running water rinsing is completed, the valve 190a and the valve 192 are opened, the drainage pump 118 is driven, and the drainage in the rinsing process is performed in the same manner as the cleaning drainage, and then the valve 160a is opened and the second air pump 116, the valve 150a, the valve 152a, the valve 154a, and the valve 156a are sequentially opened one by one, and air is supplied in the rinsing process in the same manner as the cleaning air supply. finish.

When the rinsing process after cleaning is completed, a disinfection process is then performed.
In the disinfecting process, first, the valve 178a connected to the disinfecting liquid port 134a is opened, the disinfecting liquid pump 108 is driven, and a predetermined amount of disinfecting liquid is introduced into the first cleaning tank 14a (disinfecting liquid introduction).

When a predetermined amount of the disinfectant is introduced into the first cleaning tank 14a, disinfection in each channel of the endoscope 50 is performed in the same manner as the above-described channel cleaning.
That is, the valve 162a is opened to drive the circulation pump 182, and the valve 150a, the valve 152a, the valve 154a, and the valve 156a connected to the ports that connect the respective channels of the endoscope one by one sequentially. Open for a predetermined time.
Thereby, the disinfecting liquid in the first cleaning tank 14a is circulated through each channel in the endoscope 50, and each channel of the endoscope 50 is sequentially disinfected with the disinfecting liquid (channel disinfection).

When the channel disinfection is completed, disinfection outside the endoscope 50 is performed in the same manner as the above-described external running water cleaning.
That is, the valve 180a corresponding to the water supply port 136a is opened and the circulation pump 182 is driven to circulate the disinfecting liquid in the first cleaning tank 14a outside the endoscope 50, and the endoscope 50 is cleaned with the cleaning liquid. Perform external disinfection (external running water disinfection).

When external running water disinfection is performed for a predetermined time, the valve 198a connected to the discharge port 144a is opened, and the disinfecting liquid is returned to the disinfecting liquid tank 102 (disinfecting liquid recovery).
In the cleaning machine 10 shown in the drawing, a pump or the like is not used to collect the disinfecting liquid, and the disinfecting liquid is collected in the disinfecting liquid tank 102 by dropping due to its own weight.

When the disinfecting liquid in the first cleaning tank 14 is collected in the disinfecting liquid tank 102, air is supplied to each channel of the endoscope 50 in the same manner as the cleaning air supply.
That is, the valve 160a is opened to drive the second air pump 116, and the valves 150a, 152a, 154a, and 156a are sequentially opened one by one. As a result, air is sent to each channel of the endoscope 50 from the forceps raising port 124a, the forceps port 126a, the air / water supply port 128a, and the suction port 130a, and the disinfectant remaining in the channel is supplied to the endoscope 50. (Disinfection air supply).

The sterilization process is thus completed, and then a rinsing process after sterilization is performed.
The rinsing process after disinfection is basically performed in the same manner as the rinsing process after the cleaning.
That is, first, the pressure reducing valve 168, the valve 180a, and the first valve 170 are opened to introduce a predetermined amount of tap water into the first cleaning tank 14a (introduction of tap water).
When the tap water introduction is completed, the valve 162a is opened to drive the circulation pump 182, and the valve 150a, the valve 152a, the valve 154a, and the valve 156a are sequentially opened for a predetermined time one by one. To rinse the channels of the endoscope 50. Next, the valve 180a is opened and the circulation pump 182 is driven to rinse the outside of the endoscope 50 with tap water.
When the external water rinsing is completed, the valve 190a and the valve 192 are opened, and the drain pump 118 is driven to drain the rinsing process. Thereafter, the valve 160a is opened to drive the second air pump 116, and the valve 150a, the valve 152a, the valve 154a, and the valve 156a are sequentially opened one by one to supply air in the rinsing process. The rinsing process after the disinfection process ends.

  When the rinsing process after the disinfection process is finished, the washing of the endoscope 50 by the washing machine 10 is finished, and the operator is informed that the washing of the endoscope 50 is finished due to, for example, display display or generation of warning sound. To do.

  As described above, the washing machine 10 shares many items such as a tank and a pump with the first washing tank 14a and the second washing tank 14b. Since both the water supply line 164 and the drainage line 194 have independent piping systems, it is possible to perform the same process in both cleaning tanks 14 at the same time. ) Can also be performed.

  In the cleaning machine 10, the endoscope 50 is basically cleaned as described above, but the cleaning machine 10 can perform various processes in addition to such cleaning.

As an example, if necessary, an alcohol flush for promoting drying in each channel of the endoscope 50 after washing can be performed.
When performing the alcohol flush, after the cleaning is completed, the valve 158a is opened to drive the alcohol pump 110, and the valve 150a connected to the forceps raising port 124a, the valve 152a connected to the forceps port 126a, The valve 154a connected to the air / water supply port 128a and the valve 156a connected to the suction port 130a are sequentially opened one by one for a predetermined time.
Next, in the same manner as the air supply in each step, the valve 160a is opened to drive the second air pump 116, and the valve 150a, valve 152a, valve 154a, and valve 156a are sequentially opened one by one. Then, air is supplied into each channel of the endoscope 50 to discharge alcohol, and drying by air supply is performed.
Further, the drain port 144a, the valve 190a and the valve 192 are opened, and the drain pump 118 is driven to drain the alcohol discharged into the first cleaning tank 14a.

  The washing machine 10 can also perform self-disinfection by disinfecting the water supply line 164 and the drainage line 194 with a disinfectant.

In this self-disinfection step, first, the valve 178a connected to the disinfecting liquid port 136a is opened, the disinfecting liquid pump 108 is driven, and a predetermined amount of disinfecting liquid is introduced into the first cleaning tank 14a.
