Description

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

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 (LG flexible portion) that connects 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.
Therefore, various endoscope cleaning / disinfecting apparatuses for automatically cleaning an endoscope have been put into practical use.

  As an example, the endoscope cleaning / disinfecting apparatus winds the insertion portion of the endoscope and the universal cord as disclosed in Patent Document 1, and stores the endoscope in the cleaning tank. There is known an apparatus for cleaning an endoscope by circulating a cleaning solution or a disinfecting solution through a path including the disinfecting solution (or immersing the disinfecting solution only).

Such an endoscope cleaning / disinfecting apparatus generally includes a cleaning process for cleaning an endoscope with a cleaning liquid, or further rinsing with tap water, a disinfection process for disinfecting an endoscope with a disinfecting liquid, and a water tap. The endoscope is cleaned by rinsing the endoscope with water or the like to remove the disinfectant and the like.

  Incidentally, as described above, the endoscope cleaning / disinfecting apparatus generally performs the cleaning process, the disinfection process, and the rinsing process to clean the endoscope. Here, the processing liquid (cleaning liquid, disinfecting liquid, tap water) used in each process is drained from the cleaning tank by gravity drop or a drainage pump after completion of each process. However, the treatment liquid remains in the endoscope only by discharging the treatment liquid from the washing tank by gravity drop or a drainage pump. Various problems may occur depending on the treatment liquid remaining in these endoscopes.

  For example, tap water used for rinsing remains in the endoscope after the cleaning process. The remaining tap water is mixed in the disinfecting liquid introduced into the cleaning tank in the disinfecting process that is the next process of the cleaning process, thereby diluting the disinfecting liquid. Usually, the disinfectant is collected after disinfection and used to disinfect a predetermined number of endoscopes. However, since the disinfection ability of a disinfectant decreases when it is diluted, the disinfectant disinfects quickly when the residual amount of rinse water is large, and if the degree of dilution is large, it must be replaced without being collected. Occurs. Therefore, the consumption of the disinfectant increases, leading to an increase in running cost.

The disinfectant remains in the endoscope after the disinfection process. The remaining disinfecting solution is not collected and is drained together with tap water used for rinsing in the rinsing step that is the next step of the disinfecting step. For this reason, the amount of the disinfectant collected every time cleaning is reduced, and it becomes necessary to add the disinfectant. For this reason, the consumption of the disinfectant increases, which leads to an increase in running cost.
If the disinfectant remains in the endoscope, when the operator removes the endoscope from the endoscope cleaning / disinfecting device, the operator touches the disinfectant or its volatile components, and the remaining amount of disinfectant When there are many, there is a possibility that the operator may suffer from adverse effects such as irritating odor and toxicity due to the disinfectant. Furthermore, if any disinfecting liquid remains in the endoscope, the patient may suffer from adverse effects such as irritating odor and toxicity due to the disinfecting liquid during the inspection with the endoscope.

  Tap water remains in the endoscope after the rinsing process. Although the endoscope is taken out from the endoscope cleaning / disinfecting apparatus after the rinsing process, tap water remains in the endoscope and cannot be used again as it is. Therefore, it is necessary to dry the endoscope. Such a drying operation is performed by wiping the tap water of the endoscope by an operator and drying the endoscope. Therefore, it takes time and labor to wipe off moisture. Furthermore, when the endoscope is dried, there is a possibility that various germs may propagate due to the presence of tap water remaining in the endoscope, which may cause a problem in terms of hygiene.

  Furthermore, if tap water remaining in the endoscope falls into the cleaning tank of the endoscope cleaning / disinfecting device, residual water will be present in the cleaning tank when the device is not in use, thereby There is also a risk of miscellaneous bacteria breeding.

  An object of the present invention is to eliminate the problems of the prior art described above. In an endoscope cleaning / disinfecting apparatus that performs cleaning / disinfection of an endoscope by performing a cleaning process, a disinfection process, and a rinsing process, An object of the present invention is to provide an endoscope cleaning / disinfecting apparatus capable of reducing the amount of processing liquid remaining in an endoscope after finishing the process and draining the processing liquid from the cleaning tank.

  In order to solve the above-described problems, the present invention provides an endoscope cleaning system including a cleaning tank, a holding unit that is housed in the cleaning tank and holds an endoscope, and a vibrating unit that vibrates the holding unit. A disinfection device is provided.

Here, it is preferable that the vibration means gives vibration to the holding means during or after draining the processing liquid from the cleaning tank.

When no vibration is applied (when non-vibration occurs), the support member 240, the vibration mechanism 210, and the rack 15a can be moved up and down together. When vibration is applied to the rack 15a, the space between the support member 240 and the rack 15a can be increased. Can generate relative vibration.
Furthermore, by providing the elevating drive mechanism 16a and the vibration mechanism 210 separately, the rack 15a can be vibrated while the rack 15a is raised and lowered.

In conventional endoscope cleaning and disinfecting devices, the processing liquid (cleaning liquid, disinfecting liquid, tap water) used in each cleaning process remains in the endoscope after draining the processing liquid, and remains in these endoscopes. Various problems may occur depending on the treated liquid. That is, for example, diluting the disinfecting solution due to residual rinse water before the disinfecting process, reducing the amount of recovered disinfecting solution due to the remaining disinfecting solution, and leaving the disinfecting solution after the completion of all cleaning and disinfecting steps to the operator or patient. There were some problems such as influence and propagation of miscellaneous bacteria due to rinsing water remaining after completion of all processes.
However, the endoscope cleaning / disinfecting apparatus 10 of the present invention has the vibration mechanism 210, and after finishing each process of cleaning the endoscope 70 and draining the processing liquid from the cleaning tank 14a, the rack 15a is vibrated. It can be vibrated by the mechanism 210. With such a configuration, the amount of processing liquid remaining in the endoscope 70 and the rack 15a can be reduced, and problems caused by the processing liquid remaining in the endoscope 70 and the rack 15a can be suppressed.

The rotational speed of the pinned cam 218 is not particularly limited as long as the processing liquid remaining in the endoscope 70 and the rack 15a can be removed, and may vary depending on the type and shape of the endoscope 70 to be cleaned, the cleaning process, and the like. Accordingly, it may be determined appropriately.
The position where the vibration mechanism 210 is provided is not particularly limited as long as the rack 15a holding the endoscope 70 can be stably vibrated, and can be attached to an arbitrary position of the rack 15a.

In the present embodiment, the rack 15a is pulled downward in the vertical direction by the spring 214, but an elastic member other than the spring may be used as long as the rack 15a can be urged downward. For example, an air cylinder or an oil cylinder may be used.
In the present embodiment, when the vibration mechanism 210 is not operated, the folded portion 240c of the support member 240 and the support bar 26 of the rack 15a come into contact with each other, and the support member 240 supports the rack 15a. When 210 is not operated, a gap may be provided between the folded portion 240 c and the support bar 26, and the support member 240 may support the rack 15 a via the spring 214.

  In the elevating drive mechanism 16a disposed on the left side of the rack 15a in FIG. 2, the wire 28 is connected to a support member 240 (elevation transmission unit) that constitutes the vibration means of the rack 15a, and elevates the support member 240. Thus, the rack 15a supported by the support member 240 is moved up and down. On the other hand, in the lift drive mechanism 16a disposed on the right side of the rack 15a in FIG. 2, the wire 28 is connected to the support rod 26 of the rack 15a, and the rack 15a is lifted and lowered directly.

  The two lift drive mechanisms 16a and 16a differ in that the wires 28 and 28 are connected to the support member 240 or the support rod 26, but the basic mechanism of the lift drive is the same. In the following description, the elevation drive mechanism 16a disposed on the left side of the paper surface in FIGS. 2 and 3 will be mainly described on behalf of both, and only the differences will be described with respect to the right elevation drive mechanism 16a.

The guide 24 is a rail-shaped member that is disposed to face the side surface of the rack 15a.
The support rods 26 and 26 are rod members that are fixed to the lower side of the plate portion of the rack 15a and protrude in the horizontal direction from the rack 15a. In the lifting drive mechanism 16a on the left side in FIG. 2, the support rod 26 is supported from below by the support member 240 via the spring 214 when the vibration mechanism 210 is operated, and directly when the vibration mechanism 210 is not operated. In the support member 240, a part of the columnar portion 240 a is inserted into the rail of the guide 24. Further, in the lifting drive mechanism 16 a on the right side in FIG. 2, the support rod 26 has its tip (projecting end) inserted into the rail of the guide 24.
The support rods 27 and 27 are arranged above the support rod 26 and spaced apart from the support rod 26 by a predetermined distance.

  The endoscope cleaning / disinfecting apparatus 10 is basically configured as described above.

  Next, an example of the operation of cleaning the endoscope 70 by the cleaning / disinfecting apparatus 10 will be described. In the following description, the cleaning tank 14a is also representative, but the endoscope 70 can also be cleaned in the same manner in the 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 lid 20a is opened, and the rack 15a is raised to the stop position of the rack 15a by the lifting drive mechanism 16a.

Each tube channel is connected.
In addition, what is necessary is just to perform the connection with each channel of each channel of the endoscope 70 by the well-known means currently performed with the endoscope washing machine using a connector, a connecting pipe, etc.

When the installation of the endoscope 70 on the rack 15a is completed, the rack 15a is lowered by the elevating drive mechanism 16a and set in the cleaning tank 14a.
Thereafter, when an instruction to start cleaning is input, the cleaning / disinfecting apparatus 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 water supply line 164 passes through the water supply pipe 163a, and the water supply port 136a passes through the cleaning tank 14a. A predetermined amount of tap water is introduced inside (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 (cleaning liquid introduction).

In the cleaning / disinfecting apparatus 10, a water leakage detection step described later may be performed as necessary after the tap water is introduced in the cleaning step (between the tap water introduction and the cleaning liquid introduction).
Moreover, when not performing 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 cleaning tank 14a, the valve 162a is opened to drive the circulation pump 182a. For example, the valve 150a connected to the forceps raising port 124a and the forceps port 126a are connected. The valve 152a, the valve 154a connected to the air / water supply port 128a, and the valve 156a connected to the suction port 130a are sequentially opened for a predetermined time one by one.

When the channel cleaning is completed, the valve 180a corresponding to the water supply port 136a is opened to drive the circulation pump 182a.
Thus, the cleaning liquid in the cleaning tank 14a is circulated outside the endoscope 70, and the outside of the endoscope 70 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 cleaning tank 14 is drained (cleaning drain).
When all of the cleaning liquid in the 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 to connect to the forceps raising port 124a. The valve 150a 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.

Next, the endoscope 70 is rinsed with tap water.
The rinsing of the endoscope 70 with tap water is basically performed in the same manner as the cleaning of the endoscope 70 with the cleaning liquid except that the cleaning liquid is not introduced into the 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 cleaning tank 14a (introduction of tap water).
When a predetermined amount of tap water is introduced into the cleaning tank 14a, the valve 162a is opened, the circulation pump 182a is driven, and the valves 150a, 152a, 154a, and 156a are sequentially opened one by one. Then, each channel of the endoscope 70 is rinsed with tap water in the same manner as the channel cleaning, and then the valve 180a is opened to drive the circulation pump 182a. Rinse the exterior of the endoscope 70 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 is driven, the valve 150a, the valve 152a, the valve 154a, and the valve 156a are sequentially opened one by one to supply air in the same manner as the cleaning air supply, and the cleaning process ends.

  When the washing process is completed, the rack 15a is vibrated by the vibration mechanism 210 to drain tap water. By doing in this way, the quantity which the tap water used by the rinse in the washing | cleaning process remains in the endoscope 70 and the rack 15a can be reduced significantly, and disinfection liquid is diluted in the following disinfection process. Can be suppressed.

  In this embodiment, the cleaning of the endoscope 70 with the cleaning liquid and the rinsing of the endoscope 70 with tap water are performed as one process, but the cleaning of the endoscope 70 with the cleaning liquid and the tap water are performed. The rinsing of the endoscope 70 with water may be a separate process. That is, in the present embodiment, the endoscope 70 is cleaned in the order of the cleaning process → the disinfection process → the rinse process, but the cleaning process → the rinse process after the cleaning → the disinfection process → the rinse process after the disinfection. The endoscope 70 may be cleaned.

After draining tap water, a disinfection process is then performed.
In the disinfection 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 cleaning tank 14a (disinfecting liquid introduction).

When a predetermined amount of the disinfectant is introduced into the cleaning tank 14a, disinfection in each channel of the endoscope 70 is performed in the same manner as the above-described channel cleaning.
That is, the valve 162a is opened to drive the circulation pump 182a, and the valve 150a, the valve 152a, the valve 154a, and the valve 156a connected to the ports that connect the channels of the endoscope 70 one by one, Sequentially open for a predetermined time.
Thus, the disinfecting liquid in the cleaning tank 14a is circulated through each channel in the endoscope 70, and each channel of the endoscope 70 is disinfected with the disinfecting liquid (channel disinfection).

When the channel disinfection is completed, disinfection outside the endoscope 70 is performed in the same manner as in the above-described external water cleaning.
That is, the valve 180a corresponding to the water supply port 136a is opened and the circulation pump 182a is driven to circulate the disinfecting liquid in the cleaning tank 14a outside the endoscope 70, and the outside of the endoscope 70 by the cleaning liquid. Disinfect (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 / disinfecting apparatus 10 in the illustrated example, a pump or the like is not used for collecting 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 cleaning tank 14 is collected in the disinfecting liquid tank 102, air is supplied to each channel of the endoscope 70 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. Thereby, air is sent from the forceps raising port 124a, the forceps port 126a, the air / water supply port 128a, and the suction port 130a to each channel of the endoscope 70, and the disinfecting liquid remaining in the channel is supplied to the endoscope 70. (Disinfection air supply).

  When the disinfection process is completed, the rack 15a is vibrated by the vibration mechanism 210, and the disinfectant is drained. By doing in this way, it can suppress that the disinfection liquid used in the disinfection process remains in the endoscope 70 and the rack 15a, and can reduce that the collect | recovered disinfectant liquid is reduced. Further, it is possible to prevent the operator and the patient undergoing the examination by the endoscope 70 from suffering bad influences such as the irritating odor and toxicity caused by the disinfecting liquid remaining in the endoscope 70 and the rack 15a.

The draining of the disinfectant solution is thus completed, and then a rinsing process is performed.
The rinsing process is basically performed in the same manner as the rinsing in the cleaning process.
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 cleaning tank 14a (introduction of tap water).
When the tap water introduction is completed, the valve 162a is opened to drive the circulation pump 182a, and the valve 150a, the valve 152a, the valve 154a, and the valve 156a are sequentially opened for a predetermined time one by one. Rinse each channel of the endoscope 70 with the channel rinse. Next, the valve 180a is opened to drive the circulation pump 182a, and the outside of the endoscope 70 is rinsed with tap water to rinse with external flowing 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 ends.

  When the rinsing process is completed, the rack 15a is vibrated by the vibration mechanism 210 to drain the tap water. By doing in this way, it can suppress that the tap water used in the rinse process remains in the endoscope 70 and the rack 15a, and can simplify the operation | work which wipes off the water | moisture content of the endoscope 70. FIG. Furthermore, when the endoscope 70 is dried, it is possible to suppress the propagation of germs due to moisture remaining in the endoscope 70. Moreover, when moisture remains in the rack 15a, it is possible to prevent germs from breeding in the cleaning tank 14a when the cleaning / disinfecting apparatus 10 is not used.

  When the rinsing process is completed, the cleaning of the endoscope 70 by the cleaning / disinfecting apparatus 10 is completed, and the operator is notified that the cleaning of the endoscope 70 has been completed, for example, by display display or generation of a warning sound.

  As described above, the cleaning / disinfecting apparatus 10 shares many items such as a tank and a pump with the cleaning tank 14a and the cleaning tank 14b. Since both the line 164 and the drainage line 194 have independent piping systems, it is possible to simultaneously perform the same process or simultaneously perform different processes (asynchronous processes in both tanks).

  In the cleaning / disinfecting apparatus 10, the endoscope 70 is basically cleaned as described above, but the cleaning / disinfecting apparatus 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 70 after cleaning can be performed.
When performing the alcohol flush, after the cleaning is finished, the valve 158a is opened, the alcohol pump 110 is driven, 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 70 to discharge alcohol and to dry by air supply.
At this time, the rack 15a may be vibrated by the vibrating means (vibrating mechanism 210) to drain the alcohol.
Further, the drain outlet 144a, the valve 190a and the valve 192 are opened, and the drain pump 118 is driven to drain the alcohol discharged into the cleaning tank 14a.

  The cleaning / disinfecting apparatus 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 134a is opened, the disinfecting liquid pump 108 is driven, and a predetermined amount of disinfecting liquid is introduced into the cleaning tank 14a.
Next, the valve 190a connected to the drain port 144a, the bypass valve 196, the pressure reducing valve 168, the first valve 170, the valve 180a connected to the water supply port 136a are opened, the drain pump 118 is driven, and the water supply line 164 and A disinfectant solution is circulated through a route including the drainage line 194.

In the cleaning / disinfecting apparatus 10 of the illustrated example, as a preferable example, when the self-disinfection is completed, the disinfecting liquid in the apparatus is discharged and the new disinfecting liquid tank 102 is filled.
That is, when the disinfecting liquid is circulated for a predetermined time in a path including the water supply line 164 and the drainage line 194, the valve 190a and the valve 192 are opened, the drainage pump 118 is driven, and the disinfecting liquid is discharged. Further, the valve 178a is opened, the disinfecting liquid pump 108 is driven, and all the disinfecting liquid remaining in the disinfecting liquid tank 102 is put into the cleaning tank 14a and discharged. At this time, the rack 15a may be simultaneously vibrated by the vibration means (the vibration mechanism 210) to drain the disinfectant solution.
When all the disinfecting liquid in the cleaning / disinfecting apparatus 10 is discharged, the pressure reducing valve 168, the first valve 170, and the second valve 172 are opened, and a predetermined amount of tap water is poured into the disinfecting liquid tank 102. Next, the disinfectant bottle B is attached to the two attachment portions 102A by the operator. The disinfecting liquid is introduced into the disinfecting liquid tank 102 by its own weight, for example, and the disinfecting liquid tank 102 is filled with a new disinfecting liquid.

Further, as described above, in the cleaning / disinfecting apparatus 10, if necessary, after introducing tap water in the cleaning process, water leakage detection is performed to detect damage to each channel of the endoscope 70, perforations, and the like. May be.
When the water leakage detection step is performed, when the endoscope 70 to be cleaned is set in the cleaning tank 12a, an air port 138a (138b), a water pressure detection pressure port provided in the endoscope 70, and Connect. When the introduction of tap water in the cleaning process is completed, the first air pump 114 is driven to open the pressure reducing valve 186 and the valve 184a. When the value measured by the pressure gauge 188a reaches a predetermined pressure, the driving of the first air pump 114 is stopped. This stop is preferably automatically performed in response to a signal from the pressure gauge 188a to the first air pump 114 according to the pressure measurement result.
When the pressurization is completed, it is visually confirmed that bubbles are emerging from the endoscope 70. If bubbles are present, any channel of the endoscope 70 may be leaking. Therefore, the cleaning of the endoscope 70 is stopped at this point. Alternatively, when the pressure measured by the pressure gauge 188a falls below a predetermined value within a predetermined time, any channel of the endoscope 70 may be leaked. The cleaning of the endoscope 70 is stopped. In addition, the pressure gauge 188a may issue a warning that any channel of the endoscope 70 is leaking when the pressure becomes a predetermined value or less.

In this embodiment, the rack 15a is vibrated by the vibration mechanism 210 after the cleaning process, the disinfection process, and the rinsing process, and the processing liquid is drained. However, the timing at which the rack 15a is vibrated by the vibration mechanism 210 is determined here. It is not limited. For example, the treatment liquid may be drained by the vibration mechanism 210 after any one of the cleaning process, the sterilization process, and the rinsing process, and after the cleaning process, the sterilization process, and the rinsing process. The processing liquid may be drained by the vibration mechanism 210 after any two of the steps.
That is, draining can be performed after completion of an arbitrary process among the processes.

Further, the treatment liquid may be drained by the vibration mechanism 210 even after each process is finished, that is, after the treatment liquid is drained, and while the treatment liquid is drained in each process.
However, in order to reduce the amount of the treatment liquid remaining in the endoscope 70 and the rack 15a, it is preferable that the treatment liquid is drained by the vibration mechanism 210 at least after the drainage of the treatment liquid is completed.

In the present embodiment, the amount of treatment liquid remaining in the endoscope 70 and the rack 15a is reduced by vibrating the rack 15a in the vertical direction by the vibration mechanism 210, but the direction in which the rack 15a is vibrated is not limited thereto.
For example, the spring 214 connects the side surface of the rack 15a and the surface (columnar portion 240a) facing the side surface of the rack 15a of the support member 240, and is opposite to the direction in which the spring 214 pulls the rack 15a by the cam 218 with pins. It is good also as giving the vibration of a horizontal direction to the rack 15a by pushing out the rack 15a to the side. Moreover, it is good also as giving a vibration in the diagonal direction. That is, the direction in which the vibration is applied to the rack 15a by the vibration mechanism 210 can be arbitrary.

  Although the vibration mechanism 210 is provided on the side surface side of the rack 15a, the position where the vibration mechanism 210 is provided is not limited thereto as long as vibration can be applied to the rack 15a. For example, it may be provided on the front surface or the back surface of the rack 15a.

  In the present embodiment, the vibration mechanism 210 includes the pin 212, the spring 214, the pin cam 218, and the motor 220. However, if the vibration can be applied to the rack 15a, the vibration mechanism is configured. Is not limited to this.

FIG. 9 shows a vibration mechanism 223 in another embodiment of the endoscope cleaning / disinfecting apparatus of the present invention. The vibration mechanism 223 is the same as the vibration mechanism 210 except that the pin-equipped cam 218 is changed to the cam 224. Therefore, the same members as those of the vibration mechanism 210 are denoted by the same reference numerals, and detailed description thereof is omitted.
As shown in FIG. 9, the vibration mechanism 223 includes a pin 212 attached to the rack 15a, a spring 214 provided between the support rod 26 of the rack 15a and the horizontal portion 240b of the support member 240, a cam 224, And a motor 220 (not shown) connected to the cam 224 via the shaft 222.

The cam 224 changes in length from the rotation shaft of the cam 224, and has a convex portion 224a having a long length from the rotation shaft. Further, like the cam 218 with a pin in the above-described embodiment, the cam 224 is connected to the motor 220 via the shaft 222 and engages with the pin 212 at the upper part thereof.

  For example, when the cam 224 is rotated in the direction (clockwise) indicated by the arrow in FIG. 9 by the motor 220 and the convex portion 224 a approaches the pin 212, the pin 212 gradually becomes vertical along the outer periphery of the cam 224. Pushed up in the direction. As in the case of the vibration mechanism 210 in FIG. 4, since the pin 212 is provided on the rack 15a, the pin 212 is pushed upward in the vertical direction, and the rack 15a is also pushed upward in the vertical direction.

When the cam 224 further rotates and the pin 212 moves away from the convex portion 224a, the rack 15a is pulled downward in the vertical direction by the spring 214. Therefore, the pin 212 gradually decreases in the vertical direction along the outer periphery of the cam 224. Pushed down.
When the cam 224 is rotated, the rack 15a repeats this up and down movement, so that the rack 15a can be vibrated. Even if such a vibration mechanism 223 is used, the rack 15a can be vibrated, and the amount of processing liquid remaining in the endoscope 70 and the rack 15a can be reduced.

  FIG. 10 shows a vibration mechanism 227 in another embodiment of the endoscope cleaning / disinfecting apparatus according to the present invention. The vibration mechanism 227 shown in FIG. 10 is attached between the solenoid 232, the movable iron core 234, the attachment member 236 attached to the tip of the movable iron core 234, the housing 238, and the housing 238 and the attachment member 236. And springs 228 and 230 that expand and contract in a direction parallel to the moving direction of the movable iron core 234.

The solenoid 232 generates a magnetic field by passing an electric current and acts as an electromagnet. A movable iron core 234 is provided inside the solenoid 232, and an attachment member 236 is disposed above the movable iron core 234. In addition, the solenoid 232 is disposed in the housing 238.
The attachment member 236 is provided on the upper part of the movable iron core 234, and the upper part is attached to the support bar 26.
The housing 238 is attached to the upper surface of the horizontal portion 240b of the support member 240 and houses the solenoid 232 therein. The housing 238 is provided with a hollow so that the movable iron core 234 and the mounting member 236 can move up and down.

One of the springs 228 and 230 is an elastic member that is connected to the housing 238 and the other is connected to the attachment member 236 to push up or pull the attachment member 236. The springs 228 and 230 push up the mounting member 236 so that the movable iron core 234 and the mounting member 236 do not fall downward when no current flows through the solenoid 232. Further, when the current is flowing through the solenoid 232, the mounting member 236 is pulled downward so that the movable iron core 234 and the mounting member 236 return to the position when the current is not flowing through the solenoid 232.
The springs 228 and 230 may be provided between the rack 15a and the support member 240 so as to expand and contract in parallel with the moving direction of the movable iron core 234.

FIG. 10 shows a state where no current is passed through the solenoid 232 in the vibration mechanism 227. Here, when a current is passed through the solenoid 232, the solenoid 232 is excited, a magnetic field is generated from the solenoid 232, and the solenoid 232 acts as an electromagnet.
The movable iron core 234 is attracted to the solenoid 232 by the magnetic field generated from the solenoid 232, and moves upward in FIG. Since the attachment member 236 is provided above the movable iron core 234, the attachment member 236 is also pushed upward as the movable iron core 234 moves. Further, since the attachment member 236 is attached to the support rod 26, the rack 15a is also pushed upward.

  When the current flowing through the solenoid 232 is cut off, the movable iron core 234 returns to the position where the current did not flow through the first solenoid 232 by its own weight and the springs 228 and 230, and the rack 15a also moves downward. Thus, in the vibration mechanism 227 of the present embodiment, the rack 15a can be vibrated up and down in the vertical direction by turning on and off the current flowing through the solenoid 232.

  In each of the above embodiments, in order to generate a relative vibration between the support member 240 and the rack 15a, the cam 218 with a pin, the cam 224, or the solenoid body (housing) in each vibration mechanism 210, 223, or 227. 238) is provided on the support member 240 side, and the mounting portion of the pin 212 or the movable iron core 234 is provided on the rack 15a side. However, the present invention is not limited to this. The cam 224 or the solenoid body (housing 238) may be provided on the rack 15a side, and the pin 212 or the movable iron core 234 may be provided on the support member 240 side.

  In the above embodiment, in order to vibrate the rack 15a, a vibration mechanism is provided separately from the lifting / lowering drive mechanism of the rack 15a to vibrate the rack 15a. However, the present invention is not limited to this, and the rack 15a The rack 15a may be vibrated using a motor that moves the rack up and down. That is, the rack 15a may be vibrated using the lifting drive mechanism. By doing in this way, it is not necessary to separately provide a vibration mechanism, and an increase in cost can be suppressed.

  In the above embodiment, the vibration means (vibration mechanism 210 and the support member 240) can be moved up and down together with the rack 15a by the lift drive mechanism 16a. However, the vibration mechanism is fixed in the cleaning tank and is not moved up and down. It is good. In this case, the support member is a member fixed to the inner wall of the cleaning tank or the cleaning tank, one end of the vibration mechanism is fixed to the support member, and the other end of the vibration mechanism is placed when the rack 15a is accommodated in the cleaning tank. May be configured to be connected to the rack 15a. For example, a pin can be provided on the rack 15a side, and a pin, an engagement cam, and a spring can be provided in the cleaning tank when the rack 15a is stored.

In addition, the vibration mechanism described in the above embodiment has the pins 212, the cams with pins 218, and the upper portions of the cams 224 (on the opposite side to the springs) in a state where the rack 15a to which the pins 212 are attached is pulled downward by the springs. The rack 15a is vibrated by the rotation of the cams 218 and 224. However, conversely, the pin 212 and the lower portions of the cams 218 and 224 (portions on the same side as the spring) are brought together with the rack 15a to which the pin 212 is attached pushed upward by a spring such as a compression spring. The rack 15a may be vibrated by engaging and rotating the cams 218 and 224.
Further, as in the above embodiment, the rack 15a may be vibrated by pushing the rack 15a downward instead of pushing the rack 15a upward by turning on and off the current flowing through the solenoid 232.

Next, still another embodiment of the present invention will be described.

The engaging members 312 (312a and 312b) are provided, and the endoscope is fixed in the horizontal direction.

  The vibration mechanism 308 vibrates the racks 306a and 306b in the vertical direction. As the vibration mechanism 308, the same vibration mechanism (vibration mechanisms 210, 223, and 227) as described above can be used. The vibration mechanism 308 is provided between the bottom surfaces of the cleaning tanks 302a and 302b and the racks 306a and 306b, and generates a relative vibration between the cleaning tanks 302a and 302b and the racks 306a and 306b.
