Description

Dental Care Tool Sterilization Device {DENTAL CARE TOOL STERILIZING DEVICE}

The present invention relates to a dental treatment tool sterilization apparatus capable of sterilizing the dental treatment tool individually in real time within a short time without separate spatial and time constraints.

Hospitals are equipped with facilities to diagnose patients and treat them accordingly. Among various hospitals, dental hospitals prevent, diagnose, and treat diseases and abnormal conditions of the maxillofacial region, including teeth, surrounding tissues, and oral cavity. In particular, dental clinics need attention to hygiene because there are many tools that enter the patient's mouth and make direct contact with body fluids.

Dental clinics typically use dental care tools called handpieces to check or treat a patient's mouth. In this case, the handpiece is equipped with a tool tip such as a bur, which is used for cutting teeth dentin, cleaning of the treatment area, saliva collection, and the like.

Conventional handpieces have been stored mainly in the cradles of unit chairs combined with patient chairs and treatment tools. Such handpieces are more likely to get blood and / or saliva in the treatment of patients and must be sterilized in several stages after use. However, the conventional medical tool sterilization method includes a plasma or high pressure steam handpiece sterilization device in a separate sterilization place, and the medical tool is separated from the air tube by a sterilization site equipped with a plasma or high pressure steam handpiece sterilization device. Must be transported to, the sterilizer must be replenished with purified water or gas, there is a problem that takes an average of 30 minutes to 3 hours once for sufficient sterilization. Accordingly, the conventional handpiece sterilization apparatus did not have sufficient conditions for sterilization in real time before patient treatment.

That is, the conventional handpiece cannot be sterilized in real time by the plasma type or high pressure steam handpiece sterilization device at a distance from the unit chair, and is often washed with alcohol. Therefore, the conventional handpiece is very likely to cause cross-infection of transferring various germs to other patients through the blood remaining after exposure to the fluid of one patient.

1 to 4, the dental medical tool sterilization apparatus 10 according to the present invention is a sterilization head for individually sterilizing the dental medical tool 20 (hereinafter, “medical tool”) together with the patient's medical treatment. 100 and the mounting case 200 is included.

First, the sterilization head 100 sterilizes the treatment tool 20 mounted inside the holder case 200 in the first direction by radiating the first ultraviolet light L1 downward according to the switching signal. The sterilization head 100 includes a power supply unit 110, a switching unit 120, a control unit 130, a first light source unit 140, and a light source protection unit 150.

The power supply unit 110 supplies operating power to components of the sterilization head 100 and the mounting case 200 including the switching unit 120, the control unit 130, and the first light source unit 140.

The switching unit 120 transmits a power control command to the control unit 130 so that the power of the power supply unit 110 is applied according to the ON / OFF operation. In addition, the switching unit 120 generates a switching signal in response to the pressing signal of the mounting case 200, and transmits the switching signal to the control unit 130.

The controller 130 receives the power control command according to the ON / OFF operation of the switching unit 120 to apply the power of the power supply unit 110. In addition, the controller 130 controls the power to be supplied from the power supply unit 110 to the first light source unit 140 according to the switching signal of the switching unit 120. In addition, the controller 130 controls power to be supplied from the power supply unit 110 to the second light source unit 230 of the mounting case 200 according to the switching signal of the switching unit 120. That is, the control unit 130 applies the power of the power supply unit 110 according to the power control command of the switching unit 120, the first and second light source unit 140, 230 corresponding to the switching signal of the switching unit 120 Control so that the applied power is supplied. Of course, the controller 130 may change the design as much as the power is supplied to the first and second light source units 140 and 230 without the switching signal according to the transmission of the pressure signal.

The first light source unit 140 is a UV-Light-Emitting Diode (LED) of type C, and is disposed under the sterilization head 100 according to a switching signal of the switching unit 120. ) Here, UV-C type means the wavelength of 200 nm-280 nm area | region in the wavelength range of UV LED. The UV-C type LED reacts with microorganisms of the treatment tool 20 at high energy to act as a sterilizing agent to destroy the DNA of the microorganisms. In other words, the first light source unit 140 may sterilize various germs in the blood remaining after exposure to the body fluid of any one patient. In addition, the first light source unit 140 may emit the first ultraviolet light L1 to the lower portion of the sterilization head 100, that is, the mounting case 200 at a conical radial angle of 120 degrees. However, the first light source unit 140 may generate some shadows in which the first ultraviolet light L1 does not shine between the limited radiation angle and the treatment tool 20. In addition, assuming that the distance to the bottom surface of the mounting case 200 is, for example, 65 mm, the first light source unit 140 may have a UV-C irradiation dose that is capable of sterilizing all bacteria such as Escherichia coli, Pseudomonas aeruginosa, and mutants. The output intensity of the first light source unit 140 may be adjusted to have energy and time.

The light source protection part 150 is formed in the form of a lens having a constant thickness on the coupling portion where the lower portion of the sterilization head 100 and the upper portion of the mounting case 200 are coupled. In addition, the light source protection unit 150 is positioned below the sterilization head 100 to cover the first light source unit 140 above the light source protection unit 150. That is, the light source protection unit 150 may protect the upper portion of the sterilization head 100 including the first light source unit 140 from being directly rubbed with the treatment tool 20 mounted on the mounting case 200. The light source protection unit 150 may be made of, for example, quartz made of silicon or silicon dioxide, which may transmit the first ultraviolet light L1. In addition, the light source protection unit 150 made of quartz may be positioned at a distance within a maximum of 10 mm from the first light source unit 140 to increase the transmittance of the first ultraviolet light L1.

Mounting case 200 is coupled to the lower portion of the sterilization head (100). In addition, the mounting case 200 sterilizes the treatment tool 20 mounted therein in the second direction by radiating the second ultraviolet light L2 upwards according to the switching signal. The upper case of the mounting case 200 is formed in an open pipe shape, and the inner surface of the pipe-shaped body is coated with ultraviolet reflection or scattering paint, so that more ultraviolet rays can be irradiated to the treatment tool 20 inserted into the inside. . The pipe-shaped body has an upper opening, a lower opening, and an insertion hole 210 for entering and exiting the treatment tool 20, and a plurality of fixing pins 220 are disposed toward the inner center thereof. The second light source unit 230 is disposed at one side. The second light source unit 230 is preferably disposed at a height of 2/3 position from the bottom of the height of the mounting case 200. Insertion hole 210 is formed to a size such that the treatment tool 20 can be inserted into the lower portion of the mounting case 200, for example.

The plurality of fixing pins 220 may be disposed at positions facing the other sides of the mounting case 200. In addition, each of the fixing pins 220 is formed in the shape of an arch curved toward the center of the mounting case 200. The fixing pin 220 is preferably formed of an elastic, ultraviolet light transmitting material. When the treatment tool 20 is inserted through the insertion hole 210, the fixing pin 220 presses the circumference of the treatment tool 20 elastically so that the treatment tool 20 is provided inside the mounting case 200. Can be fixed to settle stably. On the other hand, the elastic material fixing pin 220 may be disposed at the end of the contact sensor to transmit a signal generated when contacting the treatment tool 20 to the switching unit 120 of the sterilization head (100). The switching unit 120 may determine whether the medical treatment tool 20 is mounted according to the contact sensor signal.

The second light source unit 230 is preferably disposed at a height of 2/3 from one side of the side of the mounting case 200, in particular, below the side height of the mounting case 200. The second light source unit 200 may be disposed closer to the mounting case 200 and closer to the head of the treatment tool 20 to be mounted. In addition, the second light source unit 230 is a UV-C type LED and emits the second ultraviolet light L2 toward the side of the mounting case 200 according to the switching signal of the switching unit 120. Here, UV-C type means the wavelength of 200 nm-280 nm area | regions of the wavelength range of UV LED similarly to a 1st light source part. The second light source unit 230 emits the second ultraviolet light L2 toward the head of the treatment tool 20 at the side of the mounting case 200 at a conical radial angle of 120 degrees, for example. Some shading generated between the limited radiation angle of 140 and the treatment tool 20 can be resolved. In addition, the second light source unit 230 forms an ultraviolet cross region C by the second ultraviolet light L2 in a direction perpendicular to the first ultraviolet light L1. By increasing the amount of radiation generated, the sterilizing power can be enhanced in the patient contact area of the medical tool 20. Like the first light source 140, it corresponds to a size capable of sterilizing all bacteria such as E. coli, Pseudomonas aeruginosa, and mutants. Assuming that the distance from the lower surface of the sterilization head 100 to the lower surface of the second light source 230 is, for example, 45 mm, the second light source unit 230 may sterilize all bacteria such as Escherichia coli, Pseudomonas aeruginosa, and mutants such as the first light source 140. UV-C energy (J / Cm ² ) can be adjusted to kill any bacteria by adjusting the size and time of the output.

And a silicon sheet 211 coupled to cover the insertion hole 210 of the bottom of the mounting case 200. The silicon sheet 211 has a through-hole formed to vary the diameter in the center, the through-hole is characterized in that it further comprises an elastic ring (212). The silicon sheet 211 is preferably coated with UV protection. The silicone sheet and the elastic ring 212 may be used to prevent ultraviolet rays from leaking to the outside. The elastic ring 212 may be formed of an elastic conductor whose resistance varies according to the degree of extension, and the switching signal may be generated by determining the entry and exit of the medical tool according to the resistance change of the elastic ring. Unlike conventional sterilizers, sterilization starts for 10 minutes as soon as it is placed on the handpiece to directly sterilize each handpiece while the air tube is connected without having to remove it from the handpiece holder.

Dental treatment tool sterilization device according to the present invention composed of a holding case 200 and the sterilization head 100 of the size corresponding to the treatment tool as described above to enable sterilization treatment of the treatment tool in real time directly in front of the patient during dental treatment. This can increase patient confidence in hygiene. In addition, the dental medical tool sterilization apparatus according to an embodiment of the present invention can be sterilized immediately at the treatment table without occupying a space for performing a separate sterilization, thereby helping to save space.

On the other hand, Figure 6 is a side cross-sectional view showing a dental treatment tool sterilization apparatus 10 'according to a second embodiment of the present invention. As shown, the mounting case 200 ′ is formed in a pipe shape having a size corresponding to the diameter and length of the dental treatment tool so that the dental treatment tool is mounted therein, and the upper and lower portions thereof are closed. The lower bottom surface has an insertion hole of a corresponding size to allow the dental care tool to enter and exit. The third light source part 250 is disposed on one side of the mounting case 200 ′ and emits third ultraviolet rays to the side. The second light source unit 230 is disposed on the other side of the mounting case facing the one side side on which the third light source unit 250 is disposed to emit the second ultraviolet light in a direction facing the third light source unit 250. As shown, the second light source unit 230 and the third light source unit 250 are different in height. The second light source unit 230 is disposed at a position 2/3 of the total height at the bottom surface of the mounting case 200, and the third light source unit 250 is the second light source unit 230. It is desirable to be placed at a higher position. The second light source part and the third light source part are arranged to face each other, that is, the heights are arranged to be offset, and each has a conical radial angle of 120 degrees, so that the shadows of each other are covered, and portions where the radial angles cross are inserted. Focused on the patient's contact area of the treatment tool 20 is a faster and more powerful sterilization is possible. It is preferable that the second light source part and the third light source part use the same UV-C LED as the above-described embodiment.
