Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance notification device having a notification function necessary for maintenance of various devices and an endoscope cleaning device equipped with this notification device.

[0002]

2. Description of the Related Art In various types of equipment, generally, maintenance such as maintenance and management is performed by exchanging parts and the like that have been consumed due to the life of the equipment or by cleaning. For example, in a cleaning device for an endoscope, its maintenance is achieved by replacing a disinfectant solution, disinfecting the inside of the device, cleaning a filter, replacing an ultraviolet ray unit, and the like. The maintenance of such a cleaning device is mainly performed to maintain the hygiene of the device, and some maintenance items (for example, replacement of the UV unit) are stopped due to abnormalities or parts for convenience of the user. There is a notification function that encourages the replacement of the.

[0003]

However, since such a notification function notifies one maintenance item on a one-off basis, the user has to perform maintenance each time. For example, there are multiple parts that are about to be replaced,
Even if the notification prompting the replacement is sporadically made in a short period of time, the user cannot collectively replace the plurality of parts by the notification that is made on a one-off basis.
Therefore, the number of maintenance work is increased and the burden on the user is large.

Further, such a notification urges the replacement of only the consumables that have reached the end of their life, and even if the consumables have reached the end of their life, unless they are at the stage of the life in which the need for replacement is urged. Since it was not announced, in other words, it was not possible to know the extent of consumption of the consumables and the replacement time, so that planned maintenance could not be performed.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to perform a maintenance work systematically and efficiently perform a plurality of maintenance items collectively. The object is to provide a maintenance notification device that can be used.

[0006]

In order to solve the above-mentioned problems, the maintenance notification device of the present invention is a maintenance notification device for notifying the required time for maintenance of each mechanism in a device having a plurality of mechanisms requiring maintenance. In the device, for each of the plurality of mechanisms, detection means for detecting that they have reached a first level requiring maintenance and that they have reached a second level requiring maintenance in the near future. In response to the detection means detecting that any one of the plurality of mechanisms has reached the first level, the mechanism that has reached the first level is notified and at that time the second level is notified. It also has a notifying means for notifying other mechanisms that have reached. Further, the notification means includes storage means for storing a mechanism that has reached the second level among the plurality of mechanisms, and the storage means together with the notification for the mechanism that has reached the first level at the time of the notification. The notification to the mechanism that has reached the second level stored in is collectively made. Further, the present invention does not provide an endoscope cleaning device equipped with such a maintenance notification device.

[0007]

Not only is its life announced when one mechanism of the device reaches a first level that requires maintenance, but another mechanism has reached a second level that requires immediate maintenance. Since the notification is also made at this time, unlike the conventional method in which only one maintenance item is notified on a one-off basis, the user needs the item to be collectively maintained before the notification time when the life of the mechanism is recognized. Be informed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of the present invention. FIG. 1B shows a schematic configuration of an endoscope cleaning device 2 including the maintenance notification device 1 (see FIG. 3) of this embodiment.

The endoscope cleaning apparatus 2 has a cleaning tank 10 in which an endoscope (not shown) as an object to be cleaned is set.
Further, the cleaning tank 10 is supplied with cleaning water from the tap 12 of the water supply and a disinfecting liquid from the disinfecting tank 14 by the pipe configuration described below.

That is, the tap 12 of the water supply is connected to the cleaning water conduit 16 of the endoscope cleaning device 2, and the cleaning water conduit 1 is also connected.
Reference numeral 6 is connected to a water supply tank 22 provided in the endoscope cleaning device 2. An ultraviolet unit 18 and a water supply valve 20 are sequentially installed in the wash water pipe line 16 upstream of the water supply tank 22. Although not shown in FIG. 2, the faucet 12
The washing water conduit 16 between the UV unit and the UV unit 18 is shown in FIG.
As shown in, a separator 45 and a water softener 46 are sequentially interposed. It should be noted that the ultraviolet unit 18 is a small-sized unit, and can be provided externally to the endoscope cleaning device 2.

The washing water pipe 16 is bifurcated from the water supply tank 22, and one branched pipe 16a is connected to the injection nozzle 24 provided in the washing tank 10 via the first washing pump 23. It is connected. Injection nozzle 24
Has its injection port directed to an endoscope (not shown) set in the cleaning tank 10, and injects cleaning water toward the outer surface of the endoscope while being rotated by the rotating mechanism 27. Further, the other branch conduit 16b of the cleaning water conduit 16 is connected to a cleaning water inlet 32 provided in the cleaning tank 10 via a second cleaning pump 29 and a filter 30.

Disinfectant line 3 extending from the disinfectant tank 14.
Reference numeral 4 is connected to an antiseptic solution inlet 36 provided in the cleaning tank 10 with a liquid feed pump 33 and a filter 35 interposed therebetween. A discharge port 42 is provided at the bottom of the cleaning layer 10, and a discharge pipe 38 extending from the discharge port 42 is connected to a switching valve 39 via a filter 37. Further, the switching valve 39 has a return conduit 43 leading to the disinfectant tank.
Is connected to a discharge pipe 40 in which a suction pump 41 is interposed, and the switching valve 39 is switched by a control signal from a control circuit (not shown) to discharge the discharge pipe 38 and the discharge pipe 40. It can be connected to any of the return lines 43.

By the way, the method of sterilizing water from the faucet 12 by ultraviolet rays is more advantageous than the method of sterilizing with a sterilizing filter in the following points. That is, when a sterilizing filter is used, a water pressure of such a degree that the water flows out of the water pipe through the tap is not enough for the water to pass through the sterilizing filter, and it is necessary to increase the water pressure by a pressurizing means such as a pump. Therefore, not only a space for arranging the pump is required, but also a structure capable of withstanding high pressure is required because high-pressure water is sent, which makes the structure of the device complicated and expensive. In addition, the filter is clogged, and the filter must be replaced regularly. On the other hand, the method of sterilizing water with ultraviolet rays does not have such drawbacks. Therefore, in this embodiment, the ultraviolet unit 18 is adopted as the sterilization mechanism of the endoscope cleaning device 2.

Next, the ultraviolet unit 18 will be described. As shown in FIG. 4A, the ultraviolet unit 18 has a cylindrical housing 58 made of high-grade stainless steel. A sterilization lamp 50 is arranged in the center of the housing 58. Sterilization lamp 5 that causes ultraviolet rays
0 is connected to the electronic control unit 60 (see FIG. 3) of the maintenance notification device 1 built in the endoscope cleaning device 2 or provided separately. Also, this sterilization lamp 50
Is a low-pressure mercury discharge lamp, which has the strongest sterilizing power among ultraviolet lamps.

A quartz tube 5 is provided on the outer surface of the sterilization lamp 50.
1 is covered, and the quartz tube 51 prevents direct contact between the sterilization lamp 50 and water. Also, this keeps the external atmosphere of the sterilization lamp at a constant temperature. The UV unit 18 has a time counter or 254 nm to check its operating efficiency.
A device (not shown) for measuring the wavelength of ultraviolet rays is provided. The ultraviolet unit 18 is operated by turning on the main switch 56 (see FIG. 3) of the endoscope cleaning device 2. Further, this ultraviolet unit 18 has a bacterial reduction rate (RF) of 10 ⁶ That is all. This value is RF =
(Number of bacteria before using UV unit (in 500 ml of water))
/ (Bacteria count after using UV unit (water 500 ml
Medium)).

Further, the cleaning water pipe line 16 from the ultraviolet unit 18 to the water supply tank 22 is shortened to prevent recontamination of sterilized water. The ultraviolet unit 10 is arranged inside the endoscope cleaning apparatus 2 in such a manner that the sterilization lamp 50 can be easily replaced. The ultraviolet unit 18 is provided with drainage equipment. This is to allow the remaining water in the unit to be drained before the quartz tube 51 is removed.

By providing the ultraviolet unit 18 on the upstream side of the water supply tank 22, the cleaning water is sterilized by the ultraviolet unit 18 before being supplied to the water supply tank 22.
Ultraviolet ray unit 1 from faucet 12 through washing water line 16
The washing water sent into the housing 8 is exposed to the ultraviolet rays from the sterilization lamp 50 while flowing along the flow path 55 in the housing 58. In this case, the ultraviolet unit 18 is arranged at a position where it is constantly filled with cleaning water.

In order to improve the sterilization efficiency, the ultraviolet unit 18 may be constructed as shown in FIG. 4 (b). That is, the ultraviolet unit may be formed in a state in which two of the structures shown in FIG. 4A are connected.

In the endoscope cleaning apparatus 2 having the above structure, the water leak of the endoscope is first detected. In this, an endoscope in which gas is sealed up to a constant pressure is set in the cleaning tank 10, and the cleaning tank 1 is passed through a branch pipe line 16b of the cleaning water pipe line 16.
The endoscope is immersed in the washing water by injecting the washing water into the inside of the endoscope, and the endoscope is observed by visually observing how the enclosed gas inside the endoscope becomes bubbles and is generated from the outer surface. It detects the perforations on the outer surface. In this case, the injection of water into the cleaning tank 10 is stopped when the water level rises to a certain height by a float switch (not shown).

If it is confirmed that the outer surface of the endoscope is not punctured, then the cleaning step is performed. In this cleaning process, tap water from the faucet 12 is decelerated by the separator 45 for safety and then softened by the water softener to enter the ultraviolet unit 18. The cleaning water sterilized by the ultraviolet unit 18 is stored in the water supply tank 22 via the water supply valve 20.
The washing water stored in the water supply tank 22 is washed by the washing pump 23.
Is ejected from the nozzle 24 toward the endoscope set in the cleaning tank 10.

When the cleaning process is completed, the disinfection process is subsequently performed. In this disinfection process, the disinfectant solution in the disinfectant solution tank 14 is injected into the cleaning tank 10 via the disinfection pump 33 and the filter 35. The disinfectant solution is sufficiently immersed in the endoscope and stored in the cleaning tank 10 for a certain period of time, and then recovered through the return line 43 to the disinfectant solution tank 14 via the filter 37 and the switching valve 39. Then, the rinsing step is performed by the same operation as the cleaning step. As a maintenance, the inside of the endoscope cleaning device 2 is disinfected. This is because after emptying the water supply tank 22, the disinfectant solution is injected into the water supply tank 22, and a drain hose and a water supply hose (not shown).
And disinfect by running a disinfectant solution through the pipe where water was flowing. Further, frequent ON / OFF of the main switch 56 reduces the life of the sterilization lamp 50 and is not recommended.

Next, the maintenance notification device 1 built in the endoscope cleaning device 2 or provided as a separate body will be described. As shown in FIG. 3, the maintenance notification device 1 has an electronic control device 60. As shown in the figure, the electronic control unit 60 is a consumable item (mechanism) requiring maintenance.
Ultraviolet unit 18 as a filter, filters 30, 35,
37, the consumption level of the disinfectant solution and the contamination level of the endoscope cleaning device 2 are detected, and the detection information is used to replace the ultraviolet unit 18 or the disinfectant solution or clean the filters 30, 35, 37 via the operation panel 61. -It is provided as a notice to promote replacement and disinfection of the endoscope cleaning device 2.

The detection by the electronic control unit 60 is performed as follows, for example. That is, the ultraviolet unit 1
In No. 8, when the sterilization lamp 50 exceeds its life (10
(Including resistance up to% over), a notice prompting replacement of the sterilization lamp 50 is given. The operating time until the sterilization lamp 50 reaches the end of its life is recorded by another built-in counter unit. The operation time is defined as the time when the main switch 56 of the endoscope cleaning device 2 is ON. Of course, the consumption level of the sterilization lamp 50 is also determined by the operating time. Further, when the operating time exceeds a certain range, a notice is given to urge the quartz tube 51 to be cleaned. The life of the sterilization lamp 50 can also be detected by a time counter for checking the operation efficiency of the ultraviolet unit 18 or a device for measuring the ultraviolet wavelength of 254 nm (neither is shown).

The electronic control unit 60 always self-checks its operating state and automatically stops the use of the cleaning / disinfecting apparatus 2 when a failure occurs. Further, when the sterilization lamp 50 exceeds its life, processing is performed by the notification means described later, but as another method, the driving of the cleaning / disinfecting apparatus 2 is automatically stopped by the life of the sterilization lamp 50. You can

On the other hand, the consumption level of the filter 30 is detected as follows, for example. That is, the cleaning tank 10
The injection of washing water into the filter is stopped when the water level rises to a certain height by a float switch (not shown), and the contamination of the filter 30 is detected by measuring the injection time. In addition, it is also possible to detect the consumption level of the filter 30 by measuring the flow rate of cleaning water injected into the cleaning tank 10 per unit time using a flow rate sensor.

Similarly, the consumption level of the filter 35 is
Cleaning tank 1 from the disinfectant tank 14 via the disinfection pump 33
It is detected by measuring the time until the disinfectant solution injected into the container 0 rises to a certain height by the float switch.

The cleaning water and the disinfectant solution in the cleaning tank 10 are drained from the outlet 42, and the time until the cleaning water and the disinfectant solution are removed from the cleaning tank 10 at the time of this draining is measured with a float switch. Thus, the dirt on the filter 37 is detected.

Further, the disinfectant solution is provided with a means for measuring the concentration in the disinfectant tank, the consumption level is determined based on the change in the concentration detected by this means, and the disinfectant solution is notified when the replacement time is reached. An announcement is made.

Further, a work switch used only for the disinfection work in the endoscope cleaning device 2 is provided, and the means for recording the time and the number of times the work switch is used promotes the disinfection in the endoscope cleaning device 2. Announcement is made. That is,
Notification is given when the work switch has been used infrequently or a considerable period of time has passed since the previous disinfection work.

Next, the notification means for urging the replacement of the expendables detected as described above or the disinfection of the endoscope cleaning device 2 will be described with reference to FIG. The electronic control device 60 of the maintenance notification device 1 determines that the consumption level of the consumable item that needs to be maintained requires maintenance based on the information obtained by the above-described detection unit.
Function to judge that the level has been reached, namely, disinfectant exchange, internal disinfection of the device 2, filters 30, 35, 3
The function to judge the necessity of cleaning / replacement of 7 and replacement of the ultraviolet unit 18 (the above is called maintenance item) (second stage B) and the consumption level (second level) which will reach the end of life in the near future are reached. It has a function (first step A) of judging that. Then, when the consumption level of the consumable item requiring maintenance reaches the first level requiring maintenance, the first notice (life notice E in the figure) notifying the life of the consumable item and the consumable item will be issued soon. A second notification (display F in the figure) for notifying that the second level requiring maintenance is reached is provided.

In this case, if there is a maintenance item that has reached the first stage A, the detection information is stored (D in the figure) and not notified alone. After that, when a certain maintenance item reaches the second stage B, that item is unconditionally displayed and notified (E in the figure) to notify the end of life. Furthermore, if there is a maintenance item that has reached the first stage at this stage, that item is also displayed (F in the figure).

As described above, the maintenance notification device 1 according to the present embodiment has the first notification (in the figure) for notifying the service life of the consumable when it reaches the first level requiring maintenance. Not only the life notification E) but also the second notification (display F in the figure) notifying that the consumable has reached the second level that needs to be maintained soon. Unlike the conventional method in which only items are announced on a one-off basis, the user can know the need for items to be collectively maintained before the notice time to recognize the life of consumables.
All the maintenance work to be performed in the near future can be carried out systematically and a plurality of maintenance items can be efficiently and collectively performed. Therefore, the number of maintenance work is reduced and the burden on the user is reduced.

FIG. 5 shows a second embodiment of the present invention. The maintenance notifying device of the present embodiment is the same as the first embodiment except that the notification means is different from that of the first embodiment, and therefore only the notification means will be described. The electronic control unit of the maintenance notification device of the present embodiment requires the maintenance based on the information obtained by the detection means similar to that of the first embodiment to determine the consumption level of the consumable item that needs to be maintained. The function to judge that the first level has been reached, that is, the necessity of the disinfectant replacement, the internal disinfection of the device 2, the cleaning / replacement of the filters 30, 35, 37, and the replacement of the ultraviolet unit 18 (maintenance item) is determined. Function (third stage B), function to determine that the wear level will reach the end of life in the near future (first stage A), and function to determine that life is about to expire (second stage C) It has and. Then, when the level of consumption of the consumable item that needs to be maintained reaches the level that requires maintenance, the first notice (operation stop G in the figure) that informs the service life of the consumable item, and the consumable item will be maintained soon. A second notice (display F in the figure) notifying that the wear level that needs to be reached and the wear level that requires maintenance in a short time has been reached, and the second notice at the time of the first notice Is also provided at the same time with a collective display I.

In this case, if there is a maintenance item that has reached the first stage A, the detection information is stored (D in the figure).
₁ ) Make sure you don't announce it alone. After that, when a certain maintenance item reaches the second stage C, it is unconditionally notified to notify the need for maintenance, and if there is an item reaching the first stage A, this is also displayed (Fig. Medium F). At this time, the information that has reached the second stage C is stored (D _{2 in the} figure). Further, when a certain maintenance item reaches the third stage B, the device 2 automatically stops (G in the figure), and the maintenance items reaching the first stage A and the second stage C are also displayed (see the figure). Medium I).

In the first embodiment, since the service life was simply announced, the maintenance could be neglected.
In the present embodiment, the notification of the time when the service life is to be notified is taken into consideration by taking into consideration the hygiene of the device and is notified by the abnormal stop of the device, so that reliable maintenance can be performed. Further, by dividing the stage before the notification of informing of the life into two, it becomes easier to grasp the current situation, and the maintenance can be performed more systematically than in the first embodiment. Furthermore, the maintenance effect can be enhanced by adding the configuration of the first embodiment and the configuration of the second embodiment.

FIG. 6 shows a third embodiment of the present invention. The maintenance notifying device of the present embodiment is the same as the first embodiment except that its notification means is different from that of the first embodiment, and therefore only the notification means will be described.

In each of the above-mentioned embodiments, the maintenance item which has reached the first stage A is not displayed alone, but in the maintenance notification device of this embodiment, the item to be maintained reaches the first stage. Even when there is only one, it is displayed by button operation (H in the figure) etc. (J in the figure)
And you can announce at any time. Therefore, more planned maintenance can be performed.

[0038]

As described above, the maintenance device according to the present invention is only required to notify the service life of the mechanism, which is a consumable item, when it reaches the first level requiring maintenance. In addition, since the mechanism also notifies that the mechanism has reached the second level that requires maintenance in the near future, unlike the conventional method in which only one maintenance item is notified on a one-off basis, the user can extend the life of the mechanism. Since it is possible to know the necessity of items to be collectively maintained before the notice time to be recognized, it is possible to efficiently perform a batch of a plurality of maintenance items by performing all planned maintenance work in a planned manner. Therefore, the number of maintenance work is reduced,
The burden on the user is reduced.
