Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for purifying a dental drainage liquid and a drainage liquid suction pipe for discharging the same, and a cleaning method therefor, and in particular, to an excellent bactericidal action for dental drainage liquid, The present invention relates to a technique capable of extremely efficiently purifying the dental drainage liquid and the drainage liquid suction pipe with a good cleaning action on the drainage liquid suction pipe.

2. Description of the Related Art Generally, in dental practice, water sprayed into the oral cavity, such as when the patient's teeth are scraped, saliva of the patient, etc., is passed through a suction pipe through a suction pipe by a predetermined suction device. While being inhaled together with air from the inside, examination and treatment are being performed, but in the drainage of the water jet and saliva that are inhaled from the oral cavity of this patient, the patient's blood etc. are mixed. For this reason, such drainage liquid has become infectious industrial waste that may contain infectious pathogenic bacteria, which has been particularly problematic in recent years.

Therefore, it is necessary that the drainage aspirated from the oral cavity of such a dental patient, so-called dental drainage, is discharged to the outside after sterilizing the microorganisms such as pathogenic bacteria contained therein. is there.

However, since such dental drainage does not occur so much in a clinical setting,
At present, they are discharged as they are without any treatment.

On the other hand, in a suction pipe through which such dental drainage is circulated and drained, that is, a drainage suction pipe, the inner wall of the suction pipe contains proteins and proteins contained in saliva and blood mixed in the drainage. It is inevitable that lipids and the like will adhere and that the amount of adhesion will gradually increase as the flow rate of the drainage increases.

Therefore, even in the drainage suction pipe, the clogging of the pipe due to the protein or the like attached to the inner wall and the growth of the microorganisms such as pathogenic bacteria contained in the dental drainage in the pipe are prevented or suppressed. Although it is desirable to perform a cleaning process for removing such proteins and the like from the standpoints of cleaning, etc., in reality, such a cleaning process for the drainage suction pipe is rarely performed.

[0007] As described above, at the clinical site of dentistry,
Dental drainage and drainage suction pipes are rarely subjected to purification treatment by sterilization or cleaning, let alone a special system for purifying those dental drainage liquids and drainage suction pipes. The reality is that it has not been introduced.

Of course, without introducing such a purification system, for example, if a predetermined disinfectant is put into the dental drainage, or if a predetermined cleaning agent is allowed to flow into the drainage suction pipe. It is possible to sterilize the dental drainage liquid and wash the drainage liquid suction pipe to purify them. However, in that case, first, a predetermined germicide and a cleaning agent are separately prepared, and then,
Every time the sterilization process of the dental drainage liquid and the cleaning process of the drainage suction pipe are performed, the work of supplying the sterilizing agent and the cleaning agent to the dental drainage liquid and the drainage suction pipe must be performed. In addition, an extra work load is imposed to clean the dental drainage liquid and the drainage suction pipe.

[0009]

Here, the present invention has been made in view of the above circumstances, and the problem to be solved is to sterilize dental drainage liquid and to drain the drainage liquid. By cleaning the suction pipe, both the dental drainage liquid and the drainage liquid suction pipe can be effectively purified, and the cleaning process of the dental drainage liquid and the drainage liquid suction pipe is unnecessary. It is an object of the present invention to provide a cleaning system for a dental drainage liquid and a drainage liquid suction pipe that can be efficiently implemented without requiring a heavy work load. Another object of the present invention is to provide a method by which the dental drainage liquid and drainage suction pipe can be advantageously purified.

[0010]

In the present invention, in order to solve such a problem, in dental treatment,
A system for purifying drainage that is sucked together with air from the patient's oral cavity on a medical examination table by a suction device, and a suction pipe that guides the drainage from the patient's oral cavity to the suction device side (a) By electrolyzing an electrolytic solution obtained by dissolving chloride in water, a strongly acidic ionized water having a pH of 2.7 or less, an oxidation-reduction potential of 1000 mV or more and effective chlorine is contained on the anode side. While generating strong alkaline ionized water rich in hydroxyl ions on the cathode side, and (b) guiding the strongly acidic ionized water from the anode side of the strong electrolytic water generating means, and A strong acid that introduces the strongly acidic ionized water that has been introduced into the discharge flow path on the upstream side of the discharge flow path, including the suction pipe, through which the waste liquid flows out, relative to the discharge port to the outside in the discharge flow direction. Sex io (C) The strong alkaline ionized water is introduced from the cathode side of the strongly electrolyzed water producing means, and the strongly acidic ionized water is introduced into the discharge flow path by the strongly acidic ionized water introducing means. If not, on the upstream side in the drainage outflow direction of the suction pipe,
A strong alkaline ionized water introducing means for introducing the guided strong alkaline ionized water into the suction pipe, and the strongly acidic ionized water introduced into the discharge flow path flows out through the discharge flow path. By mixing in the drainage,
While sterilizing and purifying the drainage liquid, the strong alkaline ionized water introduced into the suction pipe is circulated in the suction pipe, thereby cleaning and purifying the suction pipe. What has been done is the feature.

That is, in the purification system for the dental drainage and drainage suction pipe according to the present invention, the pH is 2.7 or less, the oxidation-reduction potential is 1000 mV or more, and effective chlorine is contained. Since strong acidic ionized water is mixed in the dental drainage solution, a dental drainage solution in which such strongly acidic ionized water is mixed is a solution of pathogenic bacteria, etc. at pH and redox potential. The dental effluent has a value exceeding the survival limit of microorganisms, and effective dental chlorine that exhibits excellent bactericidal activity against microorganisms is contained in the dental effluent. In this, microorganisms such as pathogenic bacteria can be surely killed, and thus dental effluent can be effectively sterilized. Moreover, in such a purification system, since strongly alkaline ionized water rich in hydroxyl ions is allowed to flow in the drainage suction pipe,
Proteins, lipids, etc. adhered to the inner wall of the drainage suction pipe can be advantageously brought into contact with the strongly alkaline ionized water, whereby they can be effectively separated from the inner wall of the pipe and removed. As a result, the drainage suction pipe can be washed extremely well.

Further, in the purification system according to the present invention, as described above, the strong acidic ionized water exhibiting an excellent bactericidal action on the dental drainage liquid and the excellent cleaning power for the drainage liquid suction pipe are exhibited. The strong alkaline ionized water to be electrolyzed is, in the strong electrolyzed water producing means, only by electrolyzing an electrolytic solution in which chloride is dissolved in water, and it is possible to easily and easily form an anode side and a cathode side by one operation. Since they can be generated at the same time, it is possible to eliminate the need to separately prepare a disinfectant for sterilizing dental drainage, a cleaning agent for cleaning drainage suction pipes, etc. In addition, such strongly acidic ionized water and strongly alkaline ionized water are guided from the strongly electrolyzed water producing means by the strongly acidic ionized water introducing means and the strongly alkaline ionized water introducing means, and are discharged in the discharge flow path. When Since it can be introduced into the liquid suction pipe, respectively, strong acidic ionized water as a bactericide can be mixed into the dental drainage liquid without any special work, and a cleaning agent can be added. As a result, strong alkaline ionized water can be circulated in the drainage suction pipe.

Therefore, in the purification system for the dental drainage liquid and the drainage suction pipe according to the present invention, both the dental drainage liquid and the drainage suction pipe can be effectively and surely purified. Moreover, such a cleaning process of the dental drainage liquid and the drainage liquid suction pipe can be carried out extremely efficiently without requiring an extra work load.

Thus, in the dental drainage and drainage suction pipe purification system according to the present invention, both the dental drainage liquid and the drainage suction pipe can be effectively purified. The sterilization treatment of the dental effluent can be carried out in a state in which the protein or the like which inhibits the sterilizing action of the strongly acidic ionized water on the dental effluent is well removed from the drainage suction pipe, whereby the dental effluent can be treated The sterilization against can be performed more effectively.

Further, in the purification system for the dental drainage and drainage suction pipe according to the present invention, when the strongly acidic ionized water is not introduced into the discharge flow path by the strongly acidic ionized water introducing means. Since the strong alkaline ionized water is introduced into the drainage suction pipe by the strong alkaline ionized water introducing means, the strong acidic ionized water and the strong alkaline ionized water are discharged in the discharge flow path. Or, it can be avoided as much as possible to mix and neutralize in the drainage suction pipe, whereby the sterilizing action of the dental drainage liquid by the strongly acidic ionized water and the drainage liquid by the strongly alkaline ionized water. The cleaning action of the suction pipe can be performed more sufficiently and reliably.

Further, in the purification system for the dental drainage liquid and the drainage liquid suction pipe according to the present invention, the strong acidic ionized water having an excellent bactericidal action for the dental drainage liquid and the drainage liquid suction pipe are provided. Strong alkaline ionized water that exerts good detergency, as is generally known, is irradiated with light,
It has the property of easily neutralizing pH and oxidation-reduction potential by being brought into contact with organic substances, and effective chlorine contained in strongly acidic ionized water is surely consumed by the bactericidal action against dental drainage. Because it is a thing,
Unlike the case of sterilizing and cleaning dental drainage and drainage suction pipes using various chemicals, the occurrence of secondary pollution and persistence problems can be advantageously avoided, and strong electrolysis As the electrolytic solution electrolyzed in the water generating means,
As long as a non-toxic chloride aqueous solution is used, the safety of the strongly acidic ionized water and the strongly alkaline ionized water produced by such electrolysis to the human body can be advantageously secured, and the strongly acidic ionized water and the strongly alkaline ionized water can be secured. The handling of water can be enhanced very advantageously.

In addition, as is well known, since the strongly acidic ionic water produced by the electrolysis as described above contains a relatively large amount of active oxygen, the purification system according to the present invention It can be expected that the action of such active oxygen exerts an even more excellent bactericidal activity against dental drainage.

BEST MODE FOR CARRYING OUT THE INVENTION In order to more specifically clarify the present invention, some embodiments of the present invention will be described in detail below with reference to the drawings.

First, FIG. 1 schematically shows a purification system for a dental drainage liquid and a drainage liquid suction pipe having a structure according to the present invention. As is clear from FIG. 1, the purification system is configured such that a strong electrolyzed water producing apparatus 10 as a strong electrolyzed water producing means is connected to a drainage suction pipe 14 by a strong electrolyzed water introducing means 12. Has been done.

More specifically, the strong electrolyzed water producing apparatus 10 constituting such a purification system includes a producing apparatus main body 16, a salt water supply tank 18, a strongly acidic ionized water storage tank 20,
And a strong alkaline ionized water storage tank 22. The salt water supply tank 18 and the generator main body 16 are connected by the saline supply pipes 24, 24, and the strongly acidic ionized water storage tank 20 is provided. The strong alkaline ionized water storage tank 22 and the generator main body 16 are connected by strong electrolytic water outflow pipes 25, 25, respectively.

Further, as is clear from FIG. 2, the generator main body 16 has the same structure as the conventional one, and the electrolytic cell 26 having a predetermined volume is partitioned by the diaphragm 28 in the central portion. Thus, two reaction chambers are formed inside and configured. An anode 30 is arranged on one side of the two reaction chambers, and a cathode 32 is arranged on the other side, and one side is an anode side reaction chamber 34, while the other side is a cathode side reaction chamber 36. It is said that.
Further, in the anode side reaction chamber 34 and the cathode side reaction chamber 36, saline solution supply pipes 24, 24 extending from the saline solution supply tank 18 are attached to the upper side, and the lower side is provided with Strongly acidic ionized water storage tank 2
0 and strong electrolyzed water outflow pipes 25, 25 extending toward the strong alkaline ionized water storage tank 22 are attached (see FIG. 1). In addition, 37 and 37 are lead wires for energizing the anode 30 and the cathode 32.

Further, although not shown, the salt water supply tank 18 is adapted to guide a predetermined amount of water such as tap water, and also to supply salt as an electrolyte in accordance with the amount of the introduced water. By supplying a predetermined amount, an electrolytic solution made of a saline solution having a predetermined concentration is generated in the tank 18 and is stored. Also,
The strongly acidic ionized water storage tank 20 and the strongly alkaline ionized water storage tank 22 are the electrolytic cell 2 in the generator body 16.
6 has a much larger volume than the anode side reaction chamber 34 and the cathode side reaction chamber 36, respectively.

Thus, in the strong electrolyzed water producing apparatus 10, the saline solution as the electrolytic solution produced in the saline solution supply tank 18 is supplied to the producing apparatus main body 16 through the saline solution supply pipes 24, 24. The electrodes 30 and 32 are supplied to the anode-side reaction chamber 34 and the cathode-side reaction chamber 36 of the electrolytic cell 26 and are arranged in the reaction chambers 34 and 36, respectively.
By energizing each of the reaction chambers 34 and 36,
The supplied saline solution is electrolyzed to generate strongly acidic ionized water in the anode side reaction chamber 34, and at the same time, strongly alkaline ionized water is generated in the cathode side reaction chamber 36. Has become. Then, the strongly acidic ionized water and the strongly alkaline ionized water generated in the reaction chambers 34, 36 of the generator main body 16 flow out from the reaction chambers 34, 36 through the strong electrolytic water outflow pipes 25, 25. Therefore, the strong acid ion water storage tank 20 and the strong alkaline ion water storage tank 22 can store water separately.

Here, in particular, as the strong electrolyzed water generator 10, a strong electrolyzed water generator 10 which can give a large electric power to the electrodes 30, 32 arranged in the reaction chambers 34, 36 of the generator main body 16 is used. As a result, in the anode side reaction chamber 34 of the generator main body 16, the pH and the redox potential exceeding the survival limit of the microorganism, such as pH of 2.7 or lower and redox potential of 1000 mV or higher, are set. A strong acidic ionized water containing active chlorine and active oxygen in a relatively large amount (specifically, effective chlorine is about 5 to 60 ppm) is generated, which has excellent bactericidal activity against microorganisms. On the other hand, in the cathode side reaction chamber 36, strong alkaline ionized water having a pH of 11 or more and an oxidation-reduction potential of -800 mV or less and excellent in deproteinization action and degreasing action is generated. It has become the jar. Further, as described above, the strongly acidic ionized water storage tank 20 and the strongly alkaline ionized water storage tank 22 have a larger volume than the anode side reaction chamber 34 and the cathode side reaction chamber 36 of the generator main body 16. Until the storage capacity of the strongly acidic ionized water and the strongly alkaline ionized water in the respective water storage tanks 20 and 22 is reached, the strongly acidic ionized water and the strongly alkaline ionized water are electrolyzed in the reaction chambers 34 and 36 as described above. The generation of water is carried out continuously.

Further, as shown in FIG. 1, the drain suction pipe 14 also has the same structure as the conventional one. That is, the suction pipe 14 as a whole extends from the suction device 38 side toward a plurality of (here, two) medical examination tables 40, and a book that extends from the suction device 38 side by a predetermined length. It is composed of a tube 42 and a plurality of (here, two) branch tubes 44 extending from the main tube 42 toward the plurality of medical tables 40. The drainage suction pipe 14 is conventionally used at the end of the main pipe 42 on the suction device 38 side to separate the air and the drainage that are sucked together from the oral cavity. While being connected to a separator 46 having a structure similar to that of the one described above, the distal end portion of each branch pipe 44 on the side of the medical examination table 40 is inside the medical examination table 40.
It is connected to a suction hose 47 having a nozzle that is inserted directly into the patient's mouth.

Thus, in the drainage suction pipe 14, by operating the suction device 38, saliva or jet water sucked by the suction hoses 47 from the oral cavity of the patient on each medical examination table 40. Dental effluent such as air and air are sucked into the main pipe 42 through each branch pipe 44, further circulated in the main pipe 42 toward the suction device 38 side, and guided into the separator 46. It has become. Then, the air guided through the drainage suction pipe 14 and the dental drainage are separated in the separator 46, and the air is sucked from the separator 46 through the exhaust pipe 45.
8 is discharged to the separator drainage pipe 4
It is designed to be discharged to the outside through 8. As is clear from this, in the present embodiment, the drainage suction pipe 14, the separator 46, and the separator drainage pipe 48 constitute a drainage channel 49 for flowing out the dental drainage liquid to the outside. Is there.

On the other hand, the strong electrolyzed water introducing means 12 for connecting the drainage suction pipe 14 having such a structure and the strong electrolyzed water producing apparatus 10 to each other stores strongly acidic ionized water in the strongly electrolyzed water producing apparatus 10. A strongly acidic ionized water introduction pipe 50 and a strongly alkaline ionized water introduction pipe 52 extending from the tank 20 and the strongly alkaline ionized water storage tank 22, respectively;
A plurality (here, two) of switching devices 54 to which the respective introduction pipes 50 and 52 are respectively connected, and a plurality (here, a plurality of switching devices 54 that are respectively connected to the plurality of branch pipes 44 of the suction pipe 14). 2) connecting pipe 5
6 and are configured.

Further, the strongly acidic ionized water introducing pipe 50 is
Strongly acidic ionized water storage tank 20 of strong electrolyzed water generator 10
A strong acid ionized water introduction main pipe 58 extending from the lower side of the drainage suction pipe 14 and arranged along the suction main pipe 42 of the drainage suction pipe 14, and a plurality of switching devices 54 from the main pipe 58. And a plurality of (two in this case) strongly acidic ionized water introducing subpipes 60 extending toward each other and connected thereto. Further, the strong alkaline ionized water introduction pipe 52, like the strongly acidic ionized water introduction pipe 50, is a main for strong alkaline ionized water introduction extending from the lower side of the strong alkaline ionized water storage tank 22 of the strong electrolyzed water producing apparatus 10. It comprises a pipe 62 and a plurality of (here, two) sub-pipes 64 for introducing strongly alkaline ionized water, which extend from the main pipe 62 toward the plurality of switching devices 54 and are connected thereto. Although not explicitly shown in FIG. 1, each sub-pipe 6 of such a strongly acidic ionized water introduction pipe 50 and a strongly alkaline ionized water introduction pipe 52.
Reference numerals 0 and 64 denote connection pipes 56 connected to the branch pipes 44 of the drainage suction pipe 14 inside the switching devices 54.
It is connected to.

Although not shown, each switching device 54 also has a switching valve therein, and the switching valve connects the connecting portion of the strongly acidic ionized water introducing subpipe 60 to the connecting pipe 56. The first switching position in which the connection portion of the strongly alkaline ionized water introducing subpipe 64 to the connecting pipe 56 is closed in a fluid-tight manner while being opened, and conversely, the connecting pipe 56 of the strongly acidic ionized water introducing subpipe 60 To the connection pipe 56 of the strongly alkaline ionized water introduction sub-pipe 64 while closing the connection to the connection pipe 5 in a fluid-tight manner, and further to connect the sub-pipes 60 and 64 to the second switching position.
It is designed such that it can be switched to a third switching position in which both the connections for 6 are closed fluid-tightly.

In particular, in such a switching device 54, the switching of the switching valve to the above-mentioned three switching positions can be automatically performed in conjunction with the operating state of the suction device 38. Has become. That is, the switching valve is switched to the first switching position while the suction device 38 is operating, and is switched to the third switching position when the suction device 38 is stopped. . And
After a lapse of a predetermined time from that state, the switching valve is switched to the second switching position for a certain time, and then the switching valve is switched to the third switching position again. Further, when the suction device 38 is operated again, the switching valve returns to the first switching position, and the switching position is maintained while the suction device 38 is operating. Is there. In addition, such a switching device 5
The automatic switching of the switching valve in 4 according to the operating condition of the suction device 38 is performed by, for example, a delay relay switch or a timer switch electrically connected to the operation / stop switch of the suction device 38 with respect to the switching device 54. It will be realized by incorporating etc.

Thus, in the strong electrolyzed water introducing means 12, the suction device 38 is operated, and the dental drainage liquid is sucked from the oral cavity of the patient through each branch pipe 44 of the drainage suction pipe 14. Meanwhile, the strongly acidic ionized water stored in the strongly acidic ionized water storage tank 20 of the strong electrolyzed water producing device 10 is stored in the strongly acidic ionized water main pipe 58 for introduction of strongly acidic ionized water. The sub-pipe 60, the switching devices 54, and the connecting pipes 56 are circulated in this order to be introduced into the branch pipes 44 of the drainage suction pipe 14, and the suction device 38 is stopped. At the same time as the suction of the dental drainage liquid from the patient's mouth is stopped, the introduction of such strongly acidic ionized water into each branch pipe 44 of the drainage liquid suction pipe 14 is stopped at that time. From the strong alkaline ionized water storage tank 22 of the strong electrolyzed water generating device 10 after a predetermined time has elapsed, the strong alkaline ionized water stored therein is stored in the strong alkaline ionized water main pipe 62 → Sub pipe 64 for introducing strong alkaline ionized water →
The switching operation 54 and the connecting pipes 56 are circulated in this order and introduced into the branch pipes 44 of the drainage suction pipe 14.

As a result, the strongly acidic ionized water is mixed in the dental drainage liquid in the drainage suction pipe 14, and together with the drainage liquid, the pipe 14 is sucked into the suction device 38 side (separator 46 side). ), And when the dental drainage liquid and the strongly acidic ionized water are not allowed to flow through the drainage suction pipe 14, only the strongly alkaline ionized water is discharged. , Inside the pipe 14,
It is designed to be distributed in the same direction as above.

As is clear from this, in the present embodiment, the strong electrolyzed water introducing means 12 has both the function of the strongly acidic ion water introducing means and the function of the strongly alkaline ion water introducing means. That is, in other words, the strong electrolyzed water introducing means 12 constitutes a strongly acidic ion water introducing means and a strong alkaline ion water introducing means.

As described above, in the purification system for the dental drainage and drainage suction pipes according to the present embodiment, the anode 30 simply arranged in the electrolytic cell 26 of the strong electrolyzed water producing apparatus 10 is used.
By simply energizing the cathode 32 and the cathode 32, the inside of the reaction chamber 34 on the anode side and the reaction chamber 36 on the cathode side of the electrode tank 26 have a pH and a redox potential exceeding the survival limit of the microorganism, and the microorganism Strongly acidic ionized water containing a large amount of effective chlorine and active oxygen that exerts excellent bactericidal activity against strong alkaline ionized water excellent in deproteinization and degreasing action can be easily and continuously produced. Then, by the strong electrolyzed water introducing means 12, such strongly acidic ionized water is allowed to flow through the dental drainage only while the dental drainage is being sucked from the oral cavity of the patient. It is automatically introduced into the pipe 14 so as to be mixed with the dental drainage liquid in the pipe 14, and the strong alkaline ionized water is drained when the dental drainage liquid is not sucked. Inside the liquid suction pipe 14 Automatically be caused to introduction, and than adapted to be caused to flow through the tubing 14,
Thereby, the dental drainage can be performed without any preparation work of the germicide for the dental drainage and the cleaning agent for the drain suction pipe, and the supply of the germicide and the cleaning agent into the drain suction pipe 14. The sterilization process for the liquid and the cleaning process for the drainage suction pipe can be performed easily and reliably.

Therefore, in the purification system for the dental drainage liquid and the drainage suction pipe according to the present embodiment, the cleaning process of the dental drainage liquid and the drainage suction pipe is extremely performed without imposing an extra work load. It can be done efficiently and reliably.

Further, in the purification system for the dental drainage and drainage suction pipe according to the present embodiment, the strongly acidic ionized water and the strongly alkaline ionized water are sucked into the drainage by the strong electrolytic water introducing means 12. Since it is adapted to be introduced into the pipe 14 from each branch pipe 44 of the pipe 14, the drain suction pipe 14 can be not only well cleaned over substantially the entire length, but can also be cleaned together with the dental drain. The inner wall of the pipe 14
It can be sterilized over almost the entire length, and the growth of microorganisms such as pathogenic bacteria contained in the drainage in the pipe 14 can be effectively prevented.

Furthermore, in such a purification system,
Depending on the operating state of the suction device 38, the strong electrolyzed water introducing means 1
Since the supply and the stop of the strongly acidic ion water and the strongly alkaline ion water into the drainage suction pipe 14 by 2 are automatically performed, the strongly acidic ion water and the strongly alkaline ion water are drained. The supply amount into the liquid suction pipe 14 depends on the suction amount of the dental drainage liquid from the oral cavity of the patient.
The amount can be increased or decreased as appropriate, whereby the sterilization process of the dental drainage liquid and the cleaning process of the drainage suction pipe 14 can be more reliably performed.

Furthermore, in the purification system for the dental drainage liquid and the drainage liquid suction pipe according to this embodiment, both the sterilization process of the dental drainage liquid and the cleaning process of the drainage liquid suction pipe 14 are performed well. Therefore, the sterilization treatment of the dental effluent can be carried out in a state where the protein or the like attached to the pipe 14 and inhibiting the sterilization action of the strongly acidic ionized water on the dental effluent is effectively removed. Therefore, the sterilization process for the dental drainage liquid can be performed more reliably.

In the purification system for the dental drainage and drainage suction pipes according to this embodiment, the strongly acidic ionized water and the strongly alkaline ionized water are supplied to the drainage suctioning pipe 14 at a predetermined level. Since the strong acidic ion water and the strong alkaline ion water are mixed in the drainage suction pipe 14 and neutralized, they are carried out separately at a time interval of. This can be avoided as much as possible, whereby the sterilizing action of the dental drainage liquid by the strongly acidic ionized water and the cleaning action of the drainage suction pipe 14 by the strongly alkaline ionized water are more sufficiently and surely performed. It can be done.

Further, as is generally known, the strongly acidic ionic water and the strongly alkaline ionic water obtained by the electrolysis method as in the present embodiment are exposed to light and contact with organic matter to cause pH and oxidation. It has the property that the reduction potential is easily neutralized, and the available chlorine contained in strongly acidic ionized water is surely consumed by the bactericidal action against microorganisms. Unlike the case of performing sterilization or cleaning of the liquid or drainage suction pipe 14, in the purification system according to the present embodiment, it is possible to advantageously avoid the occurrence of secondary pollution and residual problems.

Further, in the system for purifying the dental drainage liquid and the drainage suction pipe according to this embodiment, saline is used as the electrolytic solution electrolyzed in the strong electrolyzed water producing apparatus 10. Therefore, the safety of the strongly acidic ionized water and the strongly alkaline ionized water produced by such electrolysis to the human body can be advantageously ensured, and the handling ability for the strongly acidic ionized water and the strongly alkaline ionized water can be effectively enhanced. To get.

Further, in such strongly acidic ionized water,
As described above, since the active oxygen is contained in a large amount, the sterilizing power against the dental drainage of the strongly acidic ion water can be improved more effectively.

By the way, in the cleaning system for the dental drainage and drainage suction pipe shown in the first embodiment,
The strong electrolyzed water introducing means 12 is a branch pipe 4 of the drainage suction pipe 14.
4, the strongly acidic ionized water and the strongly alkaline ionized water can be introduced from the strongly electrolyzed water introducing means 12 through the branch pipes 44 into the main pipe 42 of the drainage suction pipe 14. However, the strong electrolyzed water introducing means 12 is
It is also possible to connect it to the main pipe 42 of the drainage suction pipe 14 so that the strongly acidic ionized water and the strongly alkaline ionized water can be directly introduced into the main pipe 42.

Specifically, for example, as shown in FIG. 3, unlike the first embodiment, the strong electrolyzed water introducing means 12 is for introducing a strong acidic ionized water which is composed of one continuous pipe. The pipe 50 and the strong alkaline ionized water introducing pipe 52, one switching device 54, and one connecting pipe 56 have a simple structure, and one strong electrolyzed water introducing means 12 is connected. Pipe 56,
In the main pipe 42 of the drainage suction pipe 14, the end portion on the upstream side in the outflow direction of the dental drainage, that is, the branch pipe 44 extending from the main pipe 42, is located at the most upstream side in the outflow direction of the dental drainage. The connecting portion of the branch pipe 44 is directly connected. Note that, in FIG. 3, members and parts having the same structure as the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted. .

Thus, in the present embodiment, while the suction device 38 is operated and the dental drainage liquid is sucked from the oral cavity of the patient through each branch pipe 44 of the drainage suction pipe 14, From the strongly acidic ionized water storage tank 20 of the strongly electrolyzed water producing apparatus 10, the strongly acidic ionized water is introduced into the strongly acidic ionized water introduction pipe 50 → the switching device 54 → the connecting pipe 56.
The main pipe 42 of the drainage suction pipe 14
It is introduced directly into the main pipe 42 so as to be mixed with the dental drainage liquid in the main pipe 42, and the suction device 38 is stopped so that the dental drainage liquid from the patient's oral cavity is stopped. When the suction of the liquid is stopped, the introduction of such strongly acidic ionized water into the main pipe 42 of the drainage suction pipe 14 is stopped, and after a lapse of a predetermined time from that time, a fixed time is passed. From the strong alkaline ionized water storage tank 22 of the strong electrolyzed water producing apparatus 10, strong alkaline ionized water is circulated in the order of strong alkaline ionized water introducing pipe 52 → connecting device 54 → connecting pipe 56, and drainage suction pipe. Introduced directly into the 14 mains 42,
It can be circulated in the main pipe 42. As is clear from this, even in the present embodiment, the strong electrolyzed water introducing means 12 is provided as in the first embodiment.
However, the strong acidic ionized water introducing means and the strong alkaline ionized water introducing means are combined, and by the strong electrolytic water introducing means 12, both the strongly acidic ionized water introducing means and the strong alkaline ionized water introducing means are combined. It is realized in an advantageous manner. Further, in the present embodiment, the extension pipe provided at the end portion on the upstream side in the drainage outflow direction of the main pipe 42 of the drainage suction pipe 14 is provided by the connection pipe 56 of the strong electrolyzed water introducing means 12. It is configured.

Therefore, in the purification system for the dental drainage liquid and the drainage suction pipe according to this embodiment, the same effects as those of the first embodiment can be advantageously enjoyed.

Especially, in such a purification system of this embodiment, since the strong electrolyzed water introducing means 12 has a simple structure, the structure of such a system is extremely advantageously simplified. That is, a special effect of being able to be performed can be achieved.

Next, in FIG. 4, unlike the above-mentioned two embodiments, a strong electrolyzed water introducing means for introducing the strongly acidic ionized water and the strongly alkaline ionized water into the discharge passage 49 and the drainage suction pipe 14. However, the strongly acidic ionized water introducing means 66 having an independent function of introducing the strongly acidic ionized water into the discharge channel 49.
And a strong alkaline ionized water introducing means 68 having an independent function of introducing strong alkaline ionized water into the drainage suction pipe 14 are shown.

As is clear from FIG. 4, in the purification system according to this embodiment, the strong acid ion water introducing means 66 is the strong acid ion water introducing pipe 50.
The switching device 54a and the connecting pipe 56, and the strongly alkaline ionized water introducing means 68 are composed of the strongly alkaline ionized water introducing pipe 52, the switching device 54b, and the connecting pipe 56, respectively. Further, in the strongly alkaline ionized water introducing means 68, the connection pipe 56 is directly connected to the main pipe 42 of the drainage suction pipe 14, while in the strongly acidic ionized water introducing means 66, The connection pipe 56 is connected to the separator 46 provided on the downstream side of the drainage suction pipe 14 in the drainage outflow direction.
Further, although not explicitly shown in the figure, the switching device 54a of the strongly acidic ionized water introducing means 66 is connected to the connecting portion between the strongly acidic ionized water introducing pipe 50 and the connecting pipe 56 while the suction device 38 is operating. Are configured to be opened, and when the suction device 38 is stopped, their connecting portions are fluid-tightly closed, and the strong alkaline ionized water introducing means 6 is provided.
The switching device 54b of No. 8 opens the connection portion of the strong alkaline ionized water introduction pipe 52 and the connection pipe 56 for a predetermined time after the suction device 38 stops and a predetermined time elapses.
During the other period, the connecting portions are configured to be fluid-tightly closed. Note that, in FIG. 4, members and parts having the same structures as those of the first and second embodiments are denoted by the same reference numerals as those of the embodiments in the drawing, and detailed description thereof is omitted. did.

Thus, in the dental drainage and drainage suction pipe purification system according to the present embodiment, while the dental drainage is being sucked from the oral cavity of the patient, the strongly acidic ionized water is
From the strongly acidic ionized water storage tank 20 of the strong electrolyzed water producing apparatus 10 is introduced into the separator 46 through the strongly acidic ionized water introducing means 66 and mixed into the dental drainage liquid in the separator 46. Moreover, when the suction of the dental drainage liquid from the oral cavity of the patient is stopped, only the strong alkaline ionized water is discharged through the strong alkaline ionized water introducing means 68 for a certain period of time. By being introduced into the main pipe 42 of the liquid suction pipe 14, the liquid can be circulated in the main pipe 42.

Therefore, in the purification system according to the present embodiment, the same effects as those of the above-mentioned embodiment can be advantageously enjoyed, and the strongly acidic ionized water is introduced into the separator 46, where the dental treatment is performed. From the place where it is mixed with the drainage liquid, the dental drainage liquid and the strong acid are generated by the vortex flow of the air guided from the inside of the oral cavity of the patient through the drainage suction pipe 14 together with the drainage liquid in the separator 46. The mixing with the ionized water can be more effectively performed, and the sterilization of the dental effluent with the strongly acidic ionized water can be performed even more advantageously.

Further, in FIG. 5, unlike the third embodiment, a drainage storage tank 70 as drainage storage means is provided on the downstream side of the separator discharge pipe 48 extending from the separator 46 in the drainage discharge direction. A strongly acidic ionized water introducing means 66 is provided and connected to the drainage storage tank 70.

More specifically, the drainage storage tank 70 has a volume larger than that of the separator 46, and the dental drainage liquid introduced from the separator 46 through the separator discharge pipe 48 is stored therein. When the amount reaches a predetermined amount, it can be discharged to the outside through the drainage storage tank discharge pipe 72. That is, here, in the drainage suction pipe 14, the separator 46, the separator drainage pipe 48, the drainage reservoir 70, and the drainage reservoir drainage pipe 72, a drainage flow path that allows the dental drainage to flow out to the outside. 49 is configured. Then, the connection pipe 56 of the strongly acidic ionized water introducing means 66 having the same structure as that of the third embodiment is connected to the waste liquid storage tank 70 which constitutes such a discharge flow path 49.
Is connected. The strong alkaline ionized water introducing means 68 is the same as in the third embodiment.
It is connected to the main pipe 42 of the drainage suction pipe 14. Further, in FIG. 5 as well, the members and parts having the same structures as those of the first, second and third embodiments are denoted by the same reference numerals as those of the embodiments in FIG. The explanation is omitted.

Thus, in the dental drainage and drainage suction pipe purification system according to the present embodiment, while the dental drainage is being sucked from the oral cavity of the patient, the strongly acidic ionized water is
From the strongly acidic ionized water storage tank 20 of the strong electrolyzed water producing apparatus 10 is introduced into the drainage storage tank 70 through the strongly acidic ionized water introducing means 66, and inside the storage tank 70,
It is designed to be mixed with dental effluent, and when the suction of dental effluent from the patient's mouth is stopped, only strong alkaline ionized water remains strong alkaline for a certain period of time. The ionized water is introduced into the main pipe 42 of the drainage suction pipe 14 through the ionized water introducing means 68 to circulate in the main pipe 42.

Therefore, in the purification system according to the present embodiment, the same effects as those of the above-described embodiment can be advantageously enjoyed, and of course, the strongly acidic ionized water has a larger volume than the separator 46, and the waste liquid is stored. Since it is introduced into the tank 70 and mixed therein with the dental effluent, the contact time of the dental effluent with the strongly acidic ion water can be effectively lengthened, and the strongly acidic ion water is The sterilization of dental effluent by means of can be carried out more advantageously.

2, 68), strong alkaline ionized water is introduced into the drainage suction pipe 14, and when strong acidic ionized water is not introduced into the discharge flow path 49, the strong alkaline ionized water is Although it was designed to be introduced into the drainage suction pipe 14, the time until the strong alkaline ionized water is introduced after the suction device 38 is stopped, and the introduction time of the strong alkaline ionized water are The amount of the dental drainage liquid to be suctioned, for example, a scale thereof is appropriately determined according to the number of patients treated within a predetermined period.

Further, the structure for selectively introducing the strongly acidic ionic water and the strongly alkaline ionic water into the drainage suction pipe 14 and the drainage passage 49 is not limited to that in the above-mentioned embodiment. For example, when the waste liquid is introduced into the separator 46 or the waste liquid storage tank 70, the strong acidic ion water is introduced into the discharge passage 49 through the strong acidic ion water introducing means. On the other hand, the introduction of the strongly acidic ionized water is stopped when the drainage is discharged from the separator 46 and the drainage storage tank 70, and then the strongly alkaline ionized water is introduced through the strongly alkaline ionized water introducing means. It is also possible to introduce the above into the drainage suction pipe 14.
