Description

[0001] APPARATUS AND METHOD FOR PROVIDING STERILIZING WATER FOR DENTAL TREATMENTS [0002]

More particularly, the present invention relates to a new dental disinfection and disinfection water supply apparatus and method capable of directly generating sterilized disinfectant water at an appropriate concentration as dental water without any separate mixing process .

A large amount of wash water is needed to clean the patient's mouth during the procedure and instruments normally used for dental treatment. In order to limit the number of bacteria per ml of dental water, it is necessary to sterilize and disinfect the dental water and prevent contamination by mixing the sterilizing disinfectant with the dental water. There was a demand.

In order to meet such a demand, there have been proposed apparatuses for mixing a medical sterilizing agent such as hypochlorous acid with water in a proper amount and supplying the water as a dental water. For example, Korean Patent Laid-Open No. 10-2016-0031163 (published on March 22, 2016) discloses a medical hypochlorous acid mixed system using wastewater resistance. According to this system, for example, a hypochlorous acid storage tank for storing hypochlorous acid having a concentration of about 30 ppm is provided, and on the other hand, a main pipeline for supplying water (raw water) to a dental treatment unit in a water purifier or the like is provided. Hypochlorous acid pumped from the hypochlorous acid reservoir is mixed with the raw water that flows constantly through the main pipeline and then provided as a dental treatment unit. It aims at uniformly adjusting the mixing ratio of raw water and hypochlorous acid by using wastewater resistance, and finally, to provide dental water having a hypochlorous acid concentration of about 4 ppm.

However, the conventional system described above is an apparatus for providing a sterilized disinfected water containing hypochlorous acid at a desired low concentration by once producing a relatively high concentration of hypochlorous acid and diluting it with water. However, considering the actual use of dental water for intermittently spraying a small amount of sterilized disinfectant water, in such a system, it is difficult to precisely adjust the mixing ratio of hypochlorous acid water and water in order to obtain a desired concentration, It is inefficient because it is difficult to obtain a desired low concentration of sterilized disinfectant and it is uneconomical because complicated instruments for producing and mixing are required. Therefore, there is still a need for an apparatus that provides an effective and economically appropriate concentration of hypochlorous acid sanitizing disinfectant as a dental water.

To be readily understood by those skilled in the art of marine technology.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view illustrating the appearance of a dental sterilizing water supply device according to an embodiment of the present invention; FIG.

1, there is illustrated a dental sterilizing and sterilizing water supply device 100 including a housing 101 having a generally rectangular parallelepiped shape and a door 102 for opening and closing a face of the housing 101. The illustrated apparatus 100 includes a control unit 110 disposed on the door 102 side, a power supply 120 and a transfer unit 170 disposed on the upper portion of the housing 101, And includes a generating unit 130 and a storage unit 150.

The control unit 110 is a part including a processor or a controller for controlling each part of the apparatus, and can be positioned, for example, adjacent to an outflow nozzle of a dental unit chair. The control unit 110 is provided with an input button such as a power switch that the user operates to turn on / off the power of the sterilizing water supply device 100, an LED (light emitting diode) And can be connected to a display means. While the power supply 120 may be, for example, a SMPS (switched mode power supply).

The generating unit 130 generates hypochlorous acid water having a concentration of about 1 to 5 ppm, for example. The storage unit 150 temporarily stores the hypochlorous acid number generated by the generation unit 130. The transfer unit 170 transfers the hypochlorous acid water from the storage unit 150 to a use place such as an outflow nozzle of a dental unit chair.

FIG. 3 is a schematic block diagram of a dental sterilizing water supplying apparatus according to an embodiment of the present invention. FIG. 4 is a schematic block diagram illustrating a detailed configuration of a generator of a dental sterilizing and disinfecting water supply device according to an embodiment of the present invention; FIG. 4 is a schematic block diagram illustrating a configuration .

2, the dental sterilizing water supply device 200 includes a control unit 210, a generating unit 230, a storage unit 250, and a transfer unit 270.

The control unit 210 is a processor or a controller unit that controls each part. The device 200 also includes a power supply, such as a SMPS, for supplying operating power to the respective parts, although not shown in the figure.

The generation unit 230 generates a hypochlorous acid number of a predetermined concentration. The generation unit 230 includes an electrolytic cell that generates an hypochlorous acid by receiving an electrolyte (for example, hydrochloric acid) from the electrolyte tank 232 and electrolyzing it. The hypochlorous acid generated in the electrolytic bath is absorbed by the water introduced from the raw water source 236 through the inflow pipe 234, so that hypochlorous acid water having a predetermined concentration can be generated. The generated hypochlorous acid water is transferred to the storage unit 250.

The generator 230 and the electrolyte tank 232 may be formed as one module to facilitate maintenance, and an example thereof is shown in FIG. 4 according to the present invention. 4, the module-shaped generator 330 includes an electrolytic tank 331, an electrolytic pump 332, a check valve 333, an electrolytic bath 334, an electrolytic power supply 335, a flow rate sensor 337 And a solenoid valve 338. The solenoid valve 338 is a solenoid valve.

The electrolyte tank 331 stores an electrolyte such as hydrochloric acid. The electrolyte in the electrolyte tank 331 is supplied to the electrolytic bath 334 by the operation of the electrolytic pump 332. A check valve 333 is provided between the electrolyte pump 332 and the electrolytic bath 334 to prevent the electrolyte from flowing backward.

The electrolytic cell 334 generates hypochlorous acid by electrolyzing the electrolyte using the electrode to which the power supplied from the electrolytic power source 335 is applied. The generated hypochlorous acid is generated as hypochlorous acid water having a predetermined concentration by being absorbed by the water flowing at a constant flow rate through the piping provided with the solenoid valve 338 and the flow rate sensor 337, The flow rate sensor 334 allows the user to sense whether the water flowing into the electrolytic bath 334 is excessive or excessive. When the water flowing into the electrolytic bath 334 is insufficient, a hypochlorous acid water having a higher concentration than the desired concentration is generated, so that an alarm device for alerting the user to the hypochlorous acid water can be added. On the other hand, when the electrolyte supplied to the electrolytic bath 334 is excessive, the electric current supplied to electrolyze the electrolytic bath 334 increases. Therefore, even when the electric current applied to the electrolytic bath 334 is excessive, an alarm device for alerting the user to the electric current may be added.

Particularly, according to the present invention, the generator 330 is configured to be capable of generating hypochlorous acid at a concentration of about 1 to 5 mg / L through current control applied to the electrolytic bath 334. To this end, the electrolytic power supply 335 supplied to the small electrolytic bath 334 is controlled by the control unit 210 (see FIG. 2) to a low current value. A small amount of electrolyte needs to be continuously introduced into the electrolytic bath 334 in order to stably produce low-concentration hypochlorous acid. For this purpose, the electrolyte pump 332 is preferably driven in accordance with the pulse signal.

Table 1 below shows the physical properties when hypochlorous acid water is produced continuously for 1 hour at a production amount of 100 L / Hr using 3% of hydrochloric acid for food addition as an electrolyte in an apparatus constructed according to an example of the present invention .

The set current value (A) Driving time / pulse value
(millisec) Current current value (A) Average concentration of hypochlorous acid (mg / L) Upper limit Ha Han 0.8 100        0.9 0.75 2.5 200 1.0 0.78 2.8 300 1.18 0.75 3.8 400 1.3 0.75 5.2 One 100 1.15 0.95 3.5 200 1.2 0.9 3.9 300 1.4 0.95 4 400 1.45 0.98 5.5 1.2 100 1.25 One 4.5 200 1.4 1.05 5 300 1.55 One 6.5 400 1.6 1.08 7

As can be seen from Table 1, when the low concentration hypochlorous acid water in the range of 1 to 5 mg / L was produced, the driving time for the pulse signal of the electrolyte pump was most stable at 100 ms. It can be seen that the variation range of the current value t in the electrolytic cell is the smallest. It can be seen that the electrolysis should proceed in the range of 0.8 ~ 1.0 A in order to produce low concentration of hypochlorous acid water with sterilizing power. Furthermore, hypochlorous acid was produced at an excess concentration above 1.2 A.

In this example, a hypochlorous acid number of 3.5 to 4 mg / L was generated at 100 L (liter) per hour at a set current value of 1.0 A, and the electrolyte was consumed at 18 mL / Hr. The capacity of the applied electrolytic cell was small enough to produce hypochlorous acid water of 100 ~ 120L / Hr.

On the other hand, the electrolytic cell was able to discharge the chlorine gas by ventilation fan, and all structures surrounding the electrolytic cell were treated with a stainless steel cover and acid paint to prevent corrosion.

Referring to FIG. 2 again, the storage unit 250 receives hypochlorous acid water from the generator 230 and stores the hypochlorous acid water therein. For example, the storage unit 250 may be a 10 L capacity PVC-made container. In particular, according to the present invention, the storage unit 250 includes a sensor (for example, a water level sensor) for sensing the amount of stored hypochlorous acid water, and the operation of the generating unit 230 may be automatically controlled according to the sensed value .

In the illustrated example, the storage unit 250 is provided with a level sensor 252, 254 for sensing the level of stored hypochlorous acid water and a safety sensor 256. The operation of automatically controlling the generator 230 by the sensed values of the water level sensors 252 and 254 and the safety sensor 256 is shown in detail in Fig.

Referring to FIG. 3, the storage unit 250 is provided with a high water level sensor 252 for sensing a predetermined high water level, a low water level sensor 254 for sensing a predetermined low water level, and a low- And a safety sensor 256 for sensing a dangerous level of danger. The sensing values of these sensors are transmitted to the control unit 210.

For example, when the full water level sensor 252 detects the full water level, the detection signal is transmitted to the control unit 210. The high water level detection signal may mean that there is no need to generate hypochlorous acid water any more because the hypochlorous acid water is full in the storage part 250. Upon receipt of the full water level detection signal, the control unit 210 may control the generation unit 230 to automatically stop the hypochlorous acid water generation operation without intervention of the user.

On the other hand, if the low-level sensor 254 senses the low level, the detection signal is also transmitted to the controller 210. The low-level sensing signal may mean that it is necessary to fill the storage unit 250 by generating hypochlorous acid water because the hypochlorous acid water is almost used in the storage unit 250. Upon receipt of the low level sensing signal, the control unit 210 controls the generating unit 230 to automatically start the hypochlorous acid water generating operation even if the user does not intervene.

Further, if the safety sensor 256 senses the danger level, the detection signal is also transmitted to the control unit 210. The dangerous level sensing signal may indicate that it is impossible to transfer the hypochlorous acid water from the storage unit 250 to the use place because the hypochlorous acid water is insufficient in the storage unit 250. [ The control unit 210 controls the bypass valve 238 to directly supply the raw water from the raw water source 236 to the destination of use (for example, an outflow nozzle of the dental unit chair) through the bypass pipe 290 Can be controlled. Accordingly, when hypochlorous acid water can not be supplied, raw water such as tap water or purified water can be temporarily supplied until the supply can be resumed again.

Referring again to FIG. 2, the transfer unit 270 transfers the hypochlorous acid water stored in the storage unit 250 to a use site (for example, an outflow nozzle of a dental unit chair).

The transfer unit 270 includes a transfer pipe 272 for connecting the outflow nozzle of the dental unit chair from the storage unit 250, a nitrogen tank 274 for keeping the pressure in the transfer pipe 272 constant, a transfer pipe 272, And a feed pump 278 for feeding the hypochlorous acid water in the reservoir 250 to the outflow nozzle through the feed pump.

For example, when the outflow nozzle of the dental unit chair is opened, the pressure of the nitrogen tank 274 is reduced, and accordingly, the feed pump 278 is operated by the pressure switch 276. The transfer pump 278 may be, for example, a diaphragm pump. In general, the diaphragm pump sucks fluid through a suction valve during downward motion and discharges fluid through an outlet valve during upward motion. Therefore, the transfer pump 278 can suck the hypochlorous acid water from the storage part 250 side in the transfer pipe 272 and discharge it to the outflow nozzle side. On the other hand, for example, when the outflow nozzle of the dental unit chair is closed, the pressure of the nitrogen tank 274 rises and the feed pump 278 is stopped by the pressure switch 276.

The pressure inside the transfer pipe 272 is kept constant by using the nitrogen tank 274 and the pressure switch 276 and the pressure of the pressure inside the transfer pipe 272 is detected by sensing the pressure change inside the transfer pipe 272, The hypochlorous acid water in the storage unit 250 can be smoothly transferred to the outflow nozzle of the dental unit chair.

The longer the length of the pipe between the nitrogen tank 274 and the pressure switch 276 is, the more the channeling phenomenon of the pressure in the transfer pipe 272 can be minimized. Therefore, a piping structure considering this is preferable. Further, it is preferable to apply a corrosion-resistant material such as a fluororesin material to all the piping of the transfer unit 270. In addition, the fitting structure for connecting pipes can adopt a one-touch fitting structure for easy maintenance and installation.

5 is a flow chart illustrating the steps of a dental sterilizing water supply method according to an embodiment of the present invention.

Referring to FIG. 5, the flow of the dirty sterilizing water supply method 500 is illustrated. First, as described above, a hypochlorous acid water of, for example, 1 to 5 ppm can be generated in the generation unit of the dental sterilizing water supply apparatus according to the embodiment of the present invention (502). The hypochlorous acid water producing step generates a hypochlorous acid water having a desired concentration by adjusting the current value applied to the electrolytic cell which generates hypochlorous acid by electrolysis, in particular, by charging the electrolytic solution. The thus generated hypochlorous acid water is stored in the storage unit (504).

The hypochlorous acid water transfer pump then operates (508) if the outflow nozzle of the dental unit chair is opened (for example, 506), for example, for the purpose of disinfecting the patient's mouth for dental care. On the other hand, if the outflow nozzle is closed (NO in 506), the hypochlorous acid water transfer pump stops operating (510).

The storage level of hypochlorous acid water stored in the storage is always sensed by the sensor (512). If the sensed water level is a high water level (514 example), the hypochlorous acid water production is stopped (516). If the sensed water level is low (YES in 518), hypochlorous acid water production is initiated (504). On the other hand, if the detected water level is the danger level (YES in 520), the supply of hypochlorous acid water is stopped and the raw water is supplied to the water outlet nozzle (522).

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course, fall within the scope of the present invention.
