Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an endoscope cleaning and disinfecting apparatus for cleaning and disinfecting an endoscope.

[0002]

2. Description of the Related Art Conventionally, endoscopes have been widely used for examination and treatment of body cavities, and air, water,
Various pipes for performing suction and the like are incorporated.
Then, in order to prevent infection and the like, each time the endoscope is used, the outer surface and the inner conduit are washed and disinfected.

[0003] In cleaning and disinfecting such endoscopes, generally,
An endoscope cleaning and disinfecting device is used. In the washing and disinfecting using the endoscope washing and disinfecting apparatus, usually, a washing step using washing water and a disinfecting step using a disinfecting solution are sequentially performed, and then a rinsing step using tap water or the like is performed.

In the washing step, for example, washing water and a detergent are supplied into a washing tank in which an endoscope is set, and a washing liquid (washing water + detergent) in the washing tank is circulated through a circulation path to perform washing. The liquid is ejected from the liquid outlet onto the outer surface of the endoscope at a high pressure. On the other hand, the cleaning liquid is circulated through another circulation path and sent to the internal conduit of the endoscope. By such a flow of the cleaning liquid, large dirt, soft dirt, light dirt, and the like adhered to the endoscope are washed away.

When ultrasonic cleaning is performed after such cleaning with a cleaning liquid, conventionally, the used cleaning liquid is provided in the cleaning tank as it is without being discharged from the cleaning tank. The diaphragm has been operated. That is, in the conventional ultrasonic cleaning, in a state where the endoscope is immersed in a cleaning solution containing a detergent, hard dirt adhered to the endoscope due to ultrasonic vibration emitted from the diaphragm or a complicated shape of the endoscope. Dirt and the like adhering to the part are strongly removed. Then, when the above cleaning step is completed, the cleaning liquid containing the detergent is discharged from the cleaning tank for the first time, and then the disinfection step is performed.

[0006]

By the way, the action of the detergent is very effective in securing the cleaning property. Therefore, as described above, when a detergent is used at the time of ultrasonic cleaning, that is, when ultrasonic cleaning is performed with the endoscope immersed in a cleaning solution containing the detergent, the chemical action of the detergent and It goes without saying that the synergistic effect with the ultrasonic power improves the cleaning power as compared with cleaning using only ultrasonic waves without using a detergent.

[0007] However, when the chemical action of the detergent is excessively applied to the endoscope, there is a concern that the durability of the endoscope may be affected. This is especially true when the chemical action of the detergent and the ultrasonic force are simultaneously applied to the endoscope.

The present invention has been made in view of the above circumstances, and an object of the present invention is to obtain a high cleaning power by using both a cleaning power by a detergent and a cleaning power by an ultrasonic wave. An object of the present invention is to provide an endoscope cleaning / disinfecting apparatus which does not affect the endoscope resistance.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an endoscope cleaning and disinfecting apparatus having a cleaning tank for cleaning and disinfecting an endoscope housed in the cleaning tank. After cleaning the endoscope in the cleaning tank with the cleaning liquid containing, the cleaning liquid is discharged at least partially from the cleaning tank, and a cleaning liquid containing no detergent is supplied into the cleaning tank,
Thereafter, the endoscope in the cleaning tank is cleaned by ultrasonic waves.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show one embodiment of the present invention. As shown in FIG. 1, the endoscope cleaning / disinfecting apparatus 1 includes a cleaning tank 2 in which an endoscope 20 to be cleaned is set. Cleaning water is supplied to the cleaning tank 2 from a water supply source (not shown) via a water supply pipe 3. A water supply valve 4 for controlling the amount of water supply is provided in the middle of the water supply pipe 3.

The cleaning tank 2 is supplied with a detergent from a detergent tank 5 through a detergent supply line 6. An on-off valve 7 is interposed in the middle of the detergent supply pipe 6.

A diaphragm 8 is provided at the bottom of the cleaning tank 2. The diaphragm 8 has, for example, a Langevin type ultrasonic vibrator attached to the bottom surface thereof, and can oscillate ultrasonic vibrations in the cleaning solution stored in the cleaning tank 2.

A drainage port is provided at the bottom of the washing tank 2, and the drainage port is connected to the drainage line 1 via an on-off valve 9.
0 is connected. A drainage pump 11 is provided in the middle of the drainage line 10, and the suction operation of the drainage pump 11 allows the cleaning liquid and the like in the cleaning tank 2 to be actively sucked and discharged to the outside. I have.

Although FIG. 1 does not show a disinfecting solution tank and pipes necessary for performing the disinfecting process for simplicity, a specific means for performing cleaning and disinfecting is an endoscope cleaning. Needless to say, it is provided in the disinfection device 1.

Next, the operation of the endoscope cleaning / disinfecting apparatus 2 having the above configuration will be described. First, the used endoscope 20 is set in the cleaning tank 2. Thereafter, various operations such as washing, disinfection, rinsing, and air supply are automatically performed by operating various operation switches (not shown). FIG. 2 shows a timing chart of the operation of various driving elements in the cleaning process.

In the cleaning step, first, the water supply valve 4 is opened,
For example, cleaning water from a water supply source such as tap water is supplied into the cleaning tank 2 via a water supply pipe 3. At this time, the on-off valve 7 is also opened, and the detergent (concentrate) in the detergent tank 5 is supplied to the detergent supply line 6.
Is supplied into the cleaning tank 2 through the cleaning tank 2. Therefore, the cleaning tank 2 stores a practical concentration of the cleaning liquid which is a mixture of the cleaning water and the detergent.

When a predetermined amount of the cleaning liquid is stored in the cleaning tank 2, the water supply valve 4 and the on-off valve 7 are closed, and in this state, the immersion cleaning in which the endoscope 20 is immersed in the cleaning liquid for a predetermined time is performed. Done.

When the chemical cleaning power of the detergent is sufficiently applied, the immersion cleaning is completed, and then the cleaning liquid is discharged. That is, the on-off valve 9 of the drain port is opened and the drain pump 11 is driven (ON), so that the detergent in the cleaning tank 2 is discharged to the outside via the drain pipe 10.

When the detergent liquid in the cleaning tank 2 is discharged to the outside, the water supply valve 4 is opened again, and the cleaning water is supplied into the cleaning tank 2 through the water supply line 3. At this time, no detergent is supplied into the cleaning tank 2.

When a predetermined amount of cleaning water is supplied into the cleaning tank 2, the water supply valve 4 is closed and the diaphragm 8 is driven (O).
N), and ultrasonic cleaning is performed. In this ultrasonic cleaning, hard dirt adhered to the endoscope 20 and dirt adhered to a complicated shape portion of the endoscope 20 are strongly removed by ultrasonic vibration emitted from the diaphragm 8.

When the above-described cleaning process is completed, subsequently, various processes such as disinfection, rinsing, and air supply are performed. As described above, the endoscope cleaning / disinfecting apparatus 1 of this embodiment
Is that the endoscope 20 is washed (immersion washing) with a washing solution containing a detergent, the used washing solution is once discharged from the washing tank 2, and then ultrasonic cleaning is performed with washing water containing no detergent. ing. Therefore, the chemical cleaning power of the detergent does not excessively act on the endoscope 20 due to the synergistic effect of the ultrasonic force, and the chemical action of the detergent and the ultrasonic force are simultaneously applied to the endoscope 20 to thereby prevent the endoscope 20 from being chemically damaged. It is possible to solve the problem of endoscope endurance degradation that is concerned. In addition, since the endoscope 20 is cleaned by using the chemical cleaning power of the detergent and the physical cleaning power of the ultrasonic wave together (not simultaneously, but in tandem), a high cleaning power can be obtained.

In this embodiment, almost all the cleaning liquid is discharged from the cleaning tank 2 after the immersion cleaning, but the amount of the cleaning liquid to be discharged from the cleaning tank 2 before the ultrasonic cleaning depends on the amount of the endoscope. As long as the resistance and the cleaning effect can be balanced, the amount may be such that the detergent concentration is reduced. That is, before the ultrasonic cleaning, a certain amount of the cleaning liquid is discharged from the cleaning tank 2,
A shortage substantially corresponding to the discharged amount may be supplemented through the water supply line 3. For example, if half of the cleaning liquid is discharged from the cleaning tank 2 before the ultrasonic cleaning and the shortage thereof is supplied with water, the ultrasonic cleaning can be performed at a detergent concentration of 1/2 that of the immersion cleaning. According to this, the chemical cleaning power of the detergent is not excessively applied to the endoscope 20, that is,
As long as the resistance of the endoscope is not affected, a high cleaning power can be obtained by a synergistic effect of the chemical action of the detergent and the ultrasonic force.

Further, in this embodiment, the detergent is supplied from the detergent tank 5 to the cleaning tank 2 through the detergent supply line 6, but the user may directly supply the detergent to the cleaning tank 2. good.

In the present embodiment, the immersion cleaning is performed in the first half of the cleaning step, but the present invention is not limited to this. For example, as shown in FIG.
The washing with flowing liquid in which the washing liquid in the washing tank 2 is circulated by the circulation pump 14 interposed in the circulation path 13 may be performed in the first half of the washing step (before the ultrasonic washing). Of course,
After the immersion cleaning and the flowing liquid cleaning are used in combination, the operation may be shifted to ultrasonic cleaning.

As washing performed before the ultrasonic washing, shower washing may be considered in addition to immersion washing and flowing liquid washing. FIG. 4 shows a configuration for performing shower cleaning. As shown, a water supply pipe 3 having a water supply valve 4 and a detergent supply pipe 6 having an on-off valve 7 and connected to a detergent tank 5 are connected to a water supply tank 21. As a result, the cleaning liquid having a practical concentration, which is a mixture of the cleaning water and the detergent, is stored in the water supply tank 21. Also,
An injection nozzle 24 is provided at the end of a pipe 23 extending from the water supply tank 21, and a cleaning liquid in the water supply tank 21 is supplied from the injection nozzle 24 to the cleaning tank 2 by an injection pump 22 provided in the pipe 23. It is designed to be sprayed toward an endoscope. Shower cleaning performed by such a configuration has a higher cleaning power than immersion cleaning.

The immersion washing, the flow washing, and the shower washing, which are performed before the ultrasonic cleaning, may be performed a plurality of times alone or in combination.
That is, for example, immersion washing → discharge of washing liquid → immersion washing →
A mode such as cleaning liquid discharge → ultrasonic cleaning or a mode of shower cleaning → cleaning liquid discharge → flow liquid cleaning → cleaning liquid discharge → ultrasonic cleaning may be considered. As described above, by performing various kinds of cleaning with the cleaning liquid a plurality of times before the ultrasonic cleaning, the cleaning power can be further increased, and the effect of removing dirt floating in the cleaning liquid increases by increasing the number of times of drainage. .

By the way, in the conventional endoscope cleaning / disinfecting apparatus, the user can arbitrarily change the cleaning time according to the use condition of the cleaning object and the degree of dirt. However, when the amount to be washed is large or when the stain is severe, the stain may not be removed even if the washing time is simply extended. Further, in a facility where the endoscope is frequently used, it is difficult to extend the cleaning time. Therefore, hereinafter, an endoscope cleaning / disinfecting apparatus in which at least the cleaning power can be arbitrarily changed according to the amount of the cleaning substance and the degree of dirt will be described.

Such an endoscope cleaning / disinfecting apparatus is shown in FIG. In the cleaning step by the endoscope cleaning / disinfecting apparatus 30, first, the cleaning water supplied from the water tap 31 is
Water is supplied from a water inlet 36 to a cleaning tank 37 via a water supply valve 32, a water supply filter 34, and a block 35. In this case, the water supply valve 32 controls the supply of the washing water, and the water supply filter 34 has a function of capturing bacteria in the washing water.

When the washing tank 37 is filled with a predetermined amount of washing water, the float valve 38 is turned on, and in this state, the flowing liquid pump 39 and the CH (channel washing) pump 40 operate. As a result, the flow liquid pump 3 through the circulation port 41
The washing water sucked into the nozzle 9 is jetted from the flowing liquid port 42 to the washing tank 37, and the outer surface of the endoscope 43 is washed by the water flow and the water pressure. Further, the washing water sucked by the CH pump 40 is sent from the tube connector 46 to the channel of the endoscope 43 connected to the tube connector 46 via the mixing block 44 and the CH valve 45. . Thus, the channel of the endoscope 43 is washed.

As shown in the drawing, since the pipe branching from the mixing block 44 communicates with the cleaning case 47 and the nozzle 48, the accessories of the endoscope 43 housed in the cleaning case 47 are cleaned. Then, the inner surface of the top cover 49 and the wall surface of the cleaning tank 37 are cleaned by the cleaning liquid ejected from the nozzle 48. A vibrator 50 is provided at the bottom of the cleaning tank 37 so that ultrasonic cleaning can be performed by the vibrator 50.

In the apparatus 30, when the washing is completed, the switching valve 51 is switched to the drain side and the drain pump 5
2 operates, and the cleaning liquid in the cleaning tank 37 is drained out of the apparatus. At this time, the air pump 54 is driven,
Air is sent from the tube connector 46 through the air filter 53 into the channel (channel) of the endoscope 43 to remove water.

The water supply pressure range when the endoscope 43 is connected to the tube connector 46 and the washing is performed depends on the endoscope 1.
It differs between the case of books and the case of multiple books. This range is stored in the apparatus in advance by study. Therefore, the cleaning tank 3
The number of the endoscopes 43 set to 7 can be determined by the pressure sensor 57 during liquid feeding.

FIG. 6 is a view of the cleaning tank 37 as viewed from above. A metal plate 58 for mounting the vibrator 50 is provided at the bottom of the cleaning tank 37. The vibrators 50 are evenly arranged on the metal plate 58. In this case, when a plurality of endoscopes 43 are set, the transducer 50
a and the transducer 50b output, and when there is one endoscope 43, only the transducer 50a outputs.
Of course, the number and arrangement of the transducers may be changed according to the endoscope's durability.

The output values of the vibrator 50, the CH pump 40, the flowing liquid pump 39, and the air pump 54 change according to the value of the pressure sensor 57. For example, the pressure sensor 57 has a standard of ² kg / cm ² , and when the pressure is lower than this value, the output of the CH pump 40 becomes higher so as to reach this value. The output of the child 50 is also increased.

Further, the number of driven vibrators 50 and the position output thereof can be arbitrarily controlled by an operation panel (not shown).
The outputs of the H pump 40, the flowing liquid pump 39, and the air pump 54 can be changed. In addition, the operation panel that can be arbitrarily set is provided with a guideline of an output value according to the amount of the cleaning object and the degree of contamination.

FIG. 7 is an output diagram when the output setting of each cleaning function is switched. In this case, three setting modes are properly used. For example, the setting is a case where the amount of washing is small or there is almost no dirt, the setting is a case where the amount of washing is large or the dirt is heavy, and the setting is a case where the amount of the washing is large and the dirt is heavy. The output values are A for setting, B for setting, and C for setting. Of course, the output increases in the order of A <B <C. These output values are determined in advance by study.

The arrangement of the vibrator 50 is shown in FIG.
As shown in FIG. 5, each part of the endoscope 43 set in the cleaning tank 37 (the insertion portion 43a, the distal end portion 43b, the operation portion 43c,
The vibrator 50 is brought into contact with the connector portion 43d), and only the vibrator 50 located at a portion of the endoscope 43 to be cleaned (a portion at which the cleaning power is to be increased) is selectively operated by an operation panel (not shown). Is also good. In this case, the output value of the vibrator 50 is fed back so as to always maintain a set value so that the output value of the endoscope 43 does not change due to variation in setting of the endoscope 43 to the device or environmental conditions.

The washing step is performed as described above.
When the washing step is completed, a disinfection step is subsequently performed.
In this disinfecting process, the disinfecting solution in the disinfecting tank 55 is supplied from the water inlet 36 into the cleaning tank 37 by the disinfecting pump 56. A predetermined amount of disinfectant is filled in the cleaning tank 37, and the outer surface of the endoscope 43 is disinfected. Further, similarly to the cleaning step, the flowing liquid pump 39 and the CH pump 40 operate to disinfect the accessories, the inner surface of the top cover 49, and the like.

When the disinfection is completed, the switching valve 51 is switched to the disinfectant tank side, and the disinfectant in the washing tank 37 is collected by the disinfectant tank 55 by natural fall. When the disinfection process is completed, the same rinsing process as the washing process is performed.
An air supply process is performed for water removal. In the air supply step, the air pump 54 operates to supply air to the air filter 5.
Air is supplied into the channel of the endoscope 43 through the mixing block 44, the mixing block 44, and the tube connector 46. Thereafter, the washing and disinfection of the endoscope 43 is completed through a known process.

Although the apparatus for cleaning and disinfecting an endoscope has been described above, it is necessary to carry out processes such as cleaning, disinfection, and sterilization in order to reuse the medical treatment tool. . In that case, an automatic cleaning and disinfecting apparatus that performs the process before sterilization in a lump is considered to be very useful. However, there is currently no dedicated automatic device for cleaning and disinfecting a medical treatment tool at a time. Therefore, it is conceivable to divert the endoscope cleaning and disinfecting apparatus as described above. However, in view of the cost, the cleaning efficiency, and the like, it is desired that an automatic cleaning and disinfecting apparatus dedicated to the treatment tool should be developed.

The inventor of the present application discloses a compact and inexpensive automatic cleaning / disinfecting apparatus dedicated to a treatment tool.
FIG. 9 shows an automatic cleaning / disinfecting apparatus dedicated to such a treatment tool. As shown in FIG.
It has a cleaning tank 66 on which the treatment tool 62 is set. The cleaning tank 66 is supplied with cleaning water from a water supply source (not shown) via a water supply line 63.

The treatment tool 62 is provided on the side wall of the cleaning tank 66.
A tube connector 78 is provided to which a tube 77 communicating with the internal conduit is connected. The tube connector 78 has a cleaning liquid supply line 7 leading to the cleaning liquid bottle 70.
2, an air supply line 83 communicating with the compressor 81 via the first switching valve 82, and a first supply line 86 connected to the disinfectant supply line 80 via the second switching valve 84. It is connected. The disinfecting solution supply line 80 communicates with the disinfecting solution bottle 71 containing the disinfecting solution, and the second switching valve 84 is connected to a second supply line 85 communicating with the cleaning tank 66.

The first switching valve 82 has a first pressurizing line 73 for supplying pressurized gas from the compressor 81 to the cleaning liquid bottle 70 and a disinfecting liquid bottle 71 for supplying pressurized gas from the compressor 81 to the cleaning liquid bottle 70. Is connected to a second pressurizing line 79 that supplies the pressure. An antiseptic solution collection line 74 is connected to an opening provided at the bottom of the cleaning tank 66 via an on-off valve 75, and the antiseptic solution collection line 74 communicates with the antiseptic solution bottle 71.

The treatment tool cleaning / disinfecting apparatus 60 having the above-described configuration is used.
When cleaning and disinfecting the treatment tool 62, the treatment tool 62 is first set in the cleaning bath 66, and the tube 77 communicating with the internal conduit of the treatment tool 62 is connected to the tube connector 78. Then, in this state, the water supply valve 4 is opened, and the cleaning water from a water supply source such as tap water is supplied into the cleaning tank 66 via the water supply line 63. At this time, a detergent may be supplied into the cleaning tank 66. Further, cleaning water is supplied into the cleaning liquid bottle 70 through the branch conduit 64 in advance, and the cleaning liquid bottle 70 is filled with the cleaning water.

When a certain amount of washing water is stored in the washing tank 66, the water supply valve 65 is closed, and the diaphragm 76 is driven. As a result, the outer surface of the treatment tool 62 is cleaned by ultrasonic waves for a certain period of time. At the same time, the first switching valve 82 is switched to the first pressurizing line 73 side, and pressurized gas from the compressor 81 is supplied to the cleaning liquid bottle 70 through the first pressurizing line 73. As a result, the cleaning water in the cleaning liquid bottle 70 is pushed out by the pressure of the pressurized gas, and is sent into the internal pipe of the treatment tool 62 via the cleaning liquid supply pipe 72. That is, the internal conduit of the treatment tool 62 is washed with the washing water.

When the above cleaning process is completed, the on-off valve 69
Is opened, and the washing water in the washing tank 66 is discharged through the drain pipe 68. Thereafter, the first switching valve 82 is switched to the second pressurizing line 79 side, and pressurized gas from the compressor 81 is supplied to the disinfecting liquid bottle 71 through the second pressurizing line 79. Thus, the disinfecting solution in the disinfecting solution bottle 71 is pushed out into the disinfecting solution supply pipe 80 by the pressure of the pressurized gas. At the beginning of the disinfection process, the second switching valve 8
4 is switched to the second supply line 85 side, so that the disinfectant flowing through the disinfectant supply line 80 is supplied into the cleaning tank 66. When a certain amount of disinfection is stored in the cleaning tank 66, the treatment tool 62 is immersed in the disinfecting solution.
That is, the treatment tool 62 is immersed and disinfected.

Also, while such immersion disinfection is being performed, the second switching valve 84 is switched to the first supply line 86 side, and the disinfectant flowing through the disinfectant supply line 80 is supplied to the treatment tool. It is fed into the internal conduit of 62. That is, the internal conduit of the treatment tool 62 is disinfected by the disinfecting solution. Of course,
The disinfecting liquid flowing through the disinfecting liquid supply pipe 80 flows into the internal pipe of the treatment tool 62 only through the first supply pipe 86,
The treatment tool 62 may be immersed in the disinfecting solution flowing into the cleaning tank 66 through the internal conduit.

When the above disinfection process is completed, the on-off valve 75 is opened, and the disinfectant in the cleaning tank 66 is returned to the disinfectant bottle 71 via the disinfectant recovery line 74. Thereafter, after a rinsing step similar to the washing step is performed, an air supply step for removing water is performed. In this air supply step, the first switching valve 82 is switched to the air supply line 83 side, and the pressurized gas from the compressor 81 is passed through the air supply line 83 to the treatment instrument 6.
2 to the internal pipeline. Thus, drainage of the internal conduit of the treatment tool 62 is performed.
