Description

Sterilization method of treatment tool for dental hospital

The present invention relates to a method for sterilizing various treatment tools used in a dental hospital, and more particularly, to a method for sterilizing treatment tools for a dental hospital that can effectively sterilize an object through ultrasonic sterilization and ozone water sterilization.

Since therapeutic tools used in dental hospitals are used by several people, except for disposables, there is a high risk of infecting fatal diseases such as hepatitis or AIDS, so they must be sterilized after use. In particular, sterilization treatment is more important because burs or scalers used for tooth preparation or polishing are inevitably stained with blood as well as microstructure of the patient's teeth or saliva when grinding teeth.

Among various equipment for sterilization of dental tools, autoclave has a principle of sterilizing microorganisms with saturated steam at high temperature and high pressure. The sterilization time of an object using an autoclave varies depending on the case, but is not short as about 20 to 30 minutes.

Since the treatment tool cannot be used while the autoclave is in operation, hospitals with many patients are equipped with multiple sets of treatment tools and are operating. In other words, several handpieces or various treatment tools are provided and used alternately.

However, in the case of small dental hospitals, since they cannot have many rather expensive handpieces, the operating time of the autoclave is often set short. Disinfection is carried out only formally. However, in hospitals that do not have autoclave equipment, tools that are essential for sterilization are only disinfected by ultrasonic disinfection or wiping with alcohol swabs.

1 is a block diagram illustrating the overall structure of a treatment tool sterilization apparatus for reference prior to a description of a treatment tool sterilization method for a dental hospital according to an embodiment of the present invention.

As shown, the treatment tool sterilizer 10 includes a sterilization tank 20, a fresh water supply unit 37, an ozone water supply unit 50, an ultrasonic generator 31, a drain unit 22, a heater 33, and a control unit. 35 , a circulation pump 24 , a dryer 25 , a gas discharge unit 27 , a collection unit 29 , a stainless steel basket 41 , and a support tray 43 .

The sterilization tank 20 is made of a container 21 and a sealing cover 23 and takes the shape of a square box. The sterilization tank 20 may be made of stainless steel. The container 21 provides a receiving space 21a open to the top. The sterilization process for the object to be sterilized is performed inside the accommodation space 21a. The sealing cover 23 is covered so as to be able to open and close on the upper part of the container 21 to seal the accommodation space 21a. If necessary, a silicone or rubber seal may be applied between the container 21 and the sealing cover 23 .

In addition, a dryer 25 is mounted on the sealing cover 23 . The dryer 25 is composed of a drying heater 25a and a switch 25b, and serves to dry the sterilization object left in the container 21 after draining fresh or ozone water. Evaporating the water on the surface of the object to be sterilized. When the drying heater 25a operates, the gas discharge unit 27 also operates at the same time to discharge the moisture inside. The type of the drying heater 25a capable of drying the sterilization object can be variously changed.

The switch 25b is a manual switch that operates the drying heater 25a. The drying heater 25a can be turned on and off automatically by the control unit 35, but can also be operated through the switch 25b.

The sterilization object includes a gripping tool 45 and a bur 47 as a treatment tool that has been used once. The gripping tool 45 includes a mirror, a curette, a scaler, tweezers, an explorer, and the like that a doctor holds and uses by hand. The gripping tool 45 has a length enough to be gripped by hand, and is sterilized while being put in the stainless steel basket 41 . The stainless steel basket 41 is a basket made of stainless steel, takes the form of a net, and has a handle 41a for easy transport. The size or shape of the stainless steel basket 41 may be varied.

In addition, the burr 47 is a grinding tip that is inserted into the head of the pneumatic handpiece. For the convenience of sterilization, the bur 47 may be sterilized while being inserted into the burr block 48 . The support tray 43 supports the burr block 48 so that the burr block 48 does not contact the bottom surface of the container 21 . The support tray 43 is also made of stainless steel and takes the form of a mesh.

The gas discharge unit 27 discharges the gas generated in the accommodation space 21a to the outside of the sterilization tank 20 and guides it to the collection unit 29 . For example, oxygen generated by heating ozone water, which will be described later, or moisture inside the accommodation space 21a during drying is discharged. The gas discharge unit 27 may be a vacuum pump or an exhaust fan.

The collecting unit 29 appropriately processes and exhausts the gas discharged from the sterilization tank 20 . For example, if ozone is detected in the captured gas, the gas is heated by itself to completely remove the ozone and then discharged into the air.

The fresh water supply unit 37 supplies the purified water to the inside of the sterilization tank 20 and is connected to the sterilization tank 20 through the fresh water supply pipe 37a. The fresh water supply from the fresh water supply unit 37 is controlled by the control unit 35 . That is, the timing or supply flow rate of fresh water supply is controlled through the control unit 35 .

The ozone water supply unit 50 dissolves ozone in fresh water provided from the outside to make ozone water, and serves to supply the generated ozone water to the sterilization tank 20 . As is known, ozone has a very strong sterilization ability, so when it is applied to a sterilization object in a dissolved state in water, various bacteria attached to the sterilization object, for example, E. coli, Shigella, Typhoid, meningitis, Sterilizes staphylococcus, staphylococcus, salmonella, cold virus, hepatitis, etc. in a short time.

The ozone water supply unit 50 includes a pressurized pump 51 for pressurizing fresh water provided from the outside, an ozone generator 53 for generating ozone, a mixer 52 for mixing ozone with fresh water transferred by the pressurized pump, and a mixer. and a bubble generator 60 that passes through fresh water and ozone and forms bubbles to increase the concentration of ozone dissolved in fresh water. The supply of ozone water through the ozone water supply unit 50 is also controlled by the control unit 35 . A description of the ozone water supply unit 50 will be described later with reference to FIGS. 2 to 6 .

The ultrasonic generator 31 transmits ultrasonic energy to the fresh water in a state in which fresh water is filled in the sterilization tank 20 , and serves to sterilize the sterilization object immersed in the fresh water by ultrasonic waves. The vibration energy of the ultrasonic wave applied to the fresh water not only sterilizes the bacteria attached to the surface of the gripping tool 45 or the bur 47, but also separates foreign substances embedded in the minute gaps on the surface of the bur 47. As long as this function can be performed, the installation position of the ultrasonic generator 31 can be changed as needed.

The drain part 22 discharges used water in the sterilization tank 20, and has a drain pipe 22a and a drain valve 22b. The drain valve 22b is opened and closed by the controller 35 . Used water means water that has been sterilized by ultrasonic waves and water that has been sterilized by ozone.

The heater 33 is a heating element fixed to the lower part of the sterilization tank 20, that is, the bottom surface of the bottom part 21b, and heats the ozone water after ozone sterilization is completed. The reason for heating the ozone water is to remove the ozone component that has completed its mission in the ozone water. When ozonated water is heated, the ozone inside the ozonized water is decomposed and turned into oxygen, leaving water. The remaining water is drained through the drain unit 22 , and oxygen is exhausted through the gas discharge unit 27 .

The heating temperature of the heater 33 may be adjusted as needed by the controller 35 . For example, heat of about 30°C may be output to decompose ozone, or fresh water may be boiled to heat and sterilize a sterilization object.

The circulation pump 24 stirs the fresh water or ozone water accommodated in the accommodation space 21a to induce the fresh water or ozone water to be in a uniform state, as well as, if necessary, to form a strong water flow to form a strong water flow, such as bacteria or bone It allows foreign substances such as tissue to be separated from the sterilization object more quickly.

2 is a block diagram showing the configuration of the ozone water supply unit 50 shown in FIG. 1 , and FIG. 3 is a partially cut-away cross-sectional view showing the internal structure of the bubble generator 60 of FIG. 2 . In addition, FIG. 4 is an exploded perspective view of the bubble generator of FIG. 3 , and FIG. 5 is a view for explaining the operating principle of the bubble generating cartridge shown in FIG. 4 . FIG. 6 is a view of a state viewed from the direction A of FIG. 5 .

The ozone water supply unit 50 plays a basic role of injecting and mixing ozone into fresh water provided from the outside, dissolving ozone in fresh water, and supplying ozone-dissolved ozone water to the sterilization tank 20 . Ozone water is water in which ozone is dissolved and has the sterilizing power of ozone as it is. In particular, it is possible to increase the concentration of ozone dissolved in fresh water by allowing fresh water and ozone to pass through to form microbubbles.

As shown, the ozone water supply unit 50 includes a pressure pump 51 , an ozone generator 53 , a mixer 52 , and a bubble generator 60 .

The pressure pump 51 pressurizes the provided fresh water to the bubble generator 60 side. As shown in FIG. 5, a plurality of Teflon bodies 75 having micropores 75a are mounted in series inside the bubble generator 60, so that ozone water can pass through the micropores at a high speed. is to pressurize

The ozone generator 53 is an equipment for silently discharging clean dry air or oxygen. It is known that ozone is produced by discharging oxygen. The ozone obtained through the discharge meets with water in the mixer 52 and begins to dissolve in the water. Ozone is not 100% dissolved in the mixer 52, but is almost completely dissolved while passing through the bubble generator 60 in a gaseous state.

The bubble generator 60 passes the fresh water in a mixed state of ozone gas and forms bubbles, thereby increasing the concentration of ozone dissolved in the fresh water to produce high-concentration ozone water.

3 and 4 , the bubble generator 60 includes a housing 61 , a bubble generating cartridge 70 , and a sealing cap 62 . The housing 61 has a space portion 61a for accommodating the bubble generating cartridge 70, a cap fixing portion 61b on one side, and a hose connection portion 61c on the other side. The cap fixing part 61b is a part to which the sealing cap 62 is coupled, and the hose connection part 61c is a part to which the hose 64 directed to the sterilization tank 20 is screwed together.

The sealing cap 62 seals the bubble generating cartridge 70 in a state coupled to the housing 61 . A hose connection portion (62b) is also provided in the central portion of the sealing cap (62). The hose connection part 62b is a part where the hose 63 connecting the mixer 52 and the bubble generating cartridge 70 is screwed together.

The bubble generating cartridge 70 is a pair of holding cases 71 that are coupled to each other to take the shape of a cylinder, three Teflon bodies 75 disposed inside the holding case 71, and upstream of the Teflon bodies 75 It includes a filter 73 installed on the side.

Each holding case 71 is a semi-cylindrical member, and has a filter mounting groove (71a) and three Teflon body mounting grooves (71b) on the inner peripheral surface. The filter mounting groove (71a) is a groove into which the filter (73) is fitted, and the Teflon body mounting groove (71b) is a groove into which the Teflon body (75) is fitted.

Between the filter mounting groove (71a) and the Teflon body mounting groove (71b) and between each Teflon body mounting groove (71b), a gap maintaining part (71c) is located. The gap maintaining portion 71c is a ring-shaped protrusion naturally made by forming the filter mounting groove 71a and the Teflon mounting groove 71b, and provides a decompression zone 76b between the adjacent Teflon bodies 75. . The decompression zone 76b passes through the micropores 75a of the Teflon body 75 and is a space in which compressed water instantaneously expands, and a description thereof will be given later.

The filter 73 passes the ozone water flowing into the bubble generator 60 and filters out fine contaminants. Since the raw material of ozone water is fresh water, there are no pollutants, but it is applied as a preventative measure. Naturally, the filter 73 may be omitted.

The Teflon body 75 is a disk-shaped member having a certain diameter and thickness, and three are arranged in series. The Teflon body 75 is, of course, manufactured by processing a Teflon material. The number of applications of the Teflon body 75 may vary as needed. For example, only one may be applied, or ten may be installed. However, as it goes downstream, the inner diameter of the micropores 75a should gradually increase.

In addition, a plurality of micropores (75a) are formed in each Teflon body (75). The micropores 75a are through passages extending in parallel in the thickness direction of the Teflon body 75 and allow ozone water to pass therein. In particular, the inner diameter D1 of the micropore 75a of the upstream Teflon body 75, the inner diameter D2 of the micropore 75a of the intermediate Teflon body 75, and the inner diameter D3 of the micropore 75a of the downstream Teflon body are different from each other. . The inner diameter size is D1<D2<D3. For example, D1 may be 0.10 mm, D2 may be 0.15 mm, and D3 may be 0.20 mm.

In the bubble generating cartridge 70 having the above configuration, when ozone water flows into the inlet 76a side, the ozone water passes through the filter 73 and then flows into the micropores 75a of the first Teflon body 75. compressed under high pressure. Since the total flow cross-sectional area of the micropores 75a is much smaller than the flow cross-sectional area of the inlet 76a, and the ozone water is continuously pressurized by the pressurization pump 51, the flow rate and pressure of the ozone water are inevitably increased. In addition, gaseous ozone molecules that have not yet been dissolved are pressed toward the water molecules while passing through the micropores and dissolved.

The pressure of ozone water passing through the first Teflon body 75 is greatly reduced as soon as it enters the decompression zone 75b, and the compressed gaseous ozone expands and bubbles. Bubbles collide with water to burst and disappear, and sometimes they meet other bubbles to enlarge and continue to dissolve in water.

The ozone water in the decompression zone 75b passes through the Teflon body 75 located in the middle, then the decompression zone 76b and the third Teflon body 75 in sequence, and the ozone is completely dissolved by the above principle. It goes to the sterilization tank 20 through the outlet part 76c in the state.

As a result, the ozone concentration in the fresh water is increased by the bubble generating cartridge 70 . Of course, as the concentration of ozone increases, the sterilization power increases.

7A to 7G are diagrams schematically showing a method for sterilizing treatment tools for a dental hospital according to an embodiment of the present invention, and FIG. 8 is a flowchart of a method for sterilizing treatment tools for a dental hospital according to an embodiment of the present invention.

As shown, the method for sterilizing treatment tools for a dental hospital according to this embodiment includes the in-place step 101, the sterilization close-closed step 103, the fresh water supply step 105, the ultrasonic output step 107, and the circulation pump operation. Step 109, the first drain step 111, the ozone water supply step 113, the circulation pump operation step 115, the heating step 117, the second drain step 119, the drying step 121, the sterilization tank It consists of an opening step 123 and an object pickup step 125 .

The positioning step 101 is a process of placing an object to be sterilized, that is, the gripping tool 45 and the burr 47, in the container 21 opened upward. At this time, the gripping tool 45 and the burr 47 are preferably placed in or supported by the stainless basket 41 or the support tray 43 . (See Fig. 7a).

The subsequent sterilization close sealing step 103 is a process of sealing the receiving space 21a of the container 21 by putting the sealing cover 23 on the container 21 on the upper part. It is also good to exhaust the air inside the accommodating space (21a) in a state in which the sealing cover 23 is attached to maintain a cleaner state.

The fresh water supply step 105 is a process of filling the sterilization tank 20 with fresh water by driving the fresh water supply unit 37 after the sealing of the sterilization tank 20 is completed by the sealing cover 23 . The water level of the fresh water is enough to completely lock the sterilization object, as shown in FIG. 7B.

The ultrasonic output step 107 is a step performed after the supply of fresh water is completed through the fresh water supply step 105, and is a process of applying ultrasonic energy to the fresh water by operating the ultrasonic generator 31 through the control unit 35. . The vibration energy of ultrasonic waves applied to the fresh water not only sterilizes bacteria, but also elutes hardened blood or living tissue embedded in the microscopic gap of the bur 47 and separates the bone tissue.

A circulation pump operation step 109 may be performed while the ultrasonic output step 107 is performed. When the circulation pump (24 in FIG. 1) is operated through the circulation pump operation step 109, the fresh water inside the sterilization tank 20 rotates along the water flow in a certain direction by the circulation pump and is mixed. The fresh water rotating inside the sterilization tank 20 prevents the fresh water around the object to be sterilized from stagnation. In other words, it is to prevent the dead body of bacteria from floating around the object to be sterilized.

The subsequent primary drain step 111 is a process in which the drain 22 is opened to drain used water to the outside. As mentioned above, the drain 22 is also controlled by the controller 35 . When the first drain step 111 is completed, the inside of the sterilization tank 20 is empty as shown in FIG. 7C .

In a state in which the sterilization tank 20 is empty, if more ultrasonic sterilization is required, the fresh water supply step 105 , the ultrasonic output step 107 , and the circulation pump operation step 109 may be repeated. However, if the ultrasonic sterilization has already been sufficiently performed, the ozone water supply step 113 is continued.

The ozone water supply step 113 is a process of shutting off the drain unit 22 and operating the ozone water supply unit 50 . When the ozone water supply unit 50 is operated, ozone water is supplied into the sterilization tank 20 . Ozone water itself has a strong sterilization power, so it completely sterilizes bacteria that may remain on the surface of the object to be sterilized. If necessary, as shown in FIG. 7D , the circulation pump operation step 115 may be performed even when the object to be sterilized is immersed in ozone water. When ozone water rotates along a water flow in a certain direction, ozone activity increases and sterilization efficiency can be improved.

When the sterilization using the ozone water is completed, the heating step 117 is performed. The heating step 117 is a process of heating the ozone water by operating the heater 33 . The heating temperature at this time is around 30℃. When ozone water is heated to the above temperature, ozone in the water vaporizes and changes into harmless oxygen.

In the heating step 117, it is preferable to operate the gas discharge unit 27 so that oxygen is discharged more rapidly from the ozone water. If all ozone components have been removed through the above process, the second drain step 119 is performed to empty the sterilization tank 20 .

The subsequent drying step 121 is a process of drying the water of the gripping tool 45 and the burr 47, which has been sterilized by operating the drying heater 25a, as shown in FIG. 7f. During the drying step 121, the gas discharge unit 27 is operated to discharge moisture. If sufficient drying has been performed through the drying step 121, the sterilization shell opening step 123 is performed. The sterilization shell opening step 123 is a process of turning off the drying heater 25a and opening the sealing cover 23 .

If the sealing cover 23 is opened, the object pickup step 125 of lifting the stainless basket 41 containing the gripping tool 45 and the support tray 43 on which the burr 47 is placed is performed, and all processes to finish

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
