Description

Technical Field

[0001] This invention relates to the field of dental examination instrument disinfection technology, specifically to a dental examination instrument disinfection device and its disinfection method. Background Technology

[0002] Oral examination instruments are indispensable tools in dental treatment. They are precisely designed and have diverse functions. Common instruments include mouth mirrors, probes, forceps, and cannulas. The mouth mirror is a tubular extension with a reflective surface that helps doctors observe hidden areas of the teeth. The probe is long and thin like a tube, with one blunt end and one sharp end, used to detect the depth of cavities and the condition of periodontal pockets. Forceps are used to pick up items such as cotton balls and pills. Cannulas are used to position and protect the probe. These instruments are mostly made of stainless steel, which is sturdy, durable, and easy to sterilize. During the examination, doctors will flexibly select instruments according to needs and conduct a comprehensive assessment of oral health through meticulous operation, providing an accurate basis for subsequent treatment and ensuring a safe and effective treatment process.

[0003] After use, dental examination instruments usually need to be disinfected and cleaned. The current disinfection and cleaning method mainly involves adding disinfectant to an ultrasonic cleaning tank. The cavitation effect can not only effectively disinfect the instruments but also remove fine dirt. Since traditional ultrasonic disinfection equipment usually does not have a rinsing function, after disinfection and cleaning, professionals need to remove the disinfection basket from the disinfection cleaning tank and then manually rinse it repeatedly to avoid disinfectant residue. The operation process is relatively cumbersome and inconvenient. We propose a dental examination instrument disinfection device and its disinfection method. Summary of the Invention

[0006] Preferably, a first sliding rod is fixedly installed on the inner side of the mounting shell, one end of the movable seat is slidably connected to the outer side of the first sliding rod, and sliding sleeves are symmetrically fixedly installed on both sides of the movable seat. One end of the assembly frame slides through the sliding sleeves, a slot is opened on the inner side of the connecting frame, and insert blocks are fixedly installed on both sides of the disinfection basket. The insert blocks and the slots are connected by insertion.

[0007] A disinfection method for a dental examination instrument disinfection device, comprising the following specific steps: S1: First, lay the oral examination instruments flat on the slanted mesh plate of the sterilization basket, while the controlled examination instruments are placed separately on the placement rack. Depending on the length of the tubes, use the pull block to pull the lever, so that the movable plate connected to the lever slides and compresses the second spring. At the same time, the movable plate causes the stop block to separate from the placement rack. Then, move the transfer case to the appropriate position and release the pull block. The stop block will then be clamped on the placement rack under the reset action of the second spring. At this time, all the controlled instruments can be adjusted to a horizontal row for easy subsequent cleaning. S2: Then, insert the disinfection basket into the connecting frame, and then use the limiting rod to rotate on the limiting shaft so that the limiting rod is locked in the mating groove of the disinfection basket mating block; S3: Subsequently, the output end of the second motor of the longitudinal component drives the second screw to rotate between the bracket and the movable seat, so that the movable rod connected to the outer thread of the second screw drives the assembly frame to slide upward. At the same time, the assembly frame raises the disinfection basket to a certain height through the connecting frame. Then, the output end of the first motor of the transverse component drives the first screw to rotate, so that the movable seat connected to the outer thread of the first screw slides towards the ultrasonic disinfection tank until the disinfection basket is above the ultrasonic disinfection tank. Then, the longitudinal component moves down, so that the disinfection basket is immersed in the disinfectant for disinfection and cleaning. S3: During the movement of the moving seat, the contact rod on the moving seat contacts the trigger rod, and at the same time, the limiting block connected to the trigger rod slides in the inner groove and compresses the first spring. The limiting block drives the dovetail block to slide in the dovetail groove. At the same time, the rack on the dovetail block meshes with the transmission gear, and the gear and the second connecting shaft are connected, so that the connecting rod rotates 90 degrees on the shaft frame through the first connecting shaft and the second connecting shaft, and is directly above the ultrasonic disinfection tank. S4: After disinfection and cleaning are completed, the longitudinal component rises to the appropriate position so that the pipe head of the inclined flushing pipe corresponds to the control instrument port on the inclined mesh plate. At this time, the inclined flushing pipe and the nozzle are connected to the rinsing water, which can easily clean the control instruments and other instruments in the disinfection basket. S5: After rinsing, the output end of the third motor in the mounting hole on the connecting rod drives the support plate to flip through the support block. Then, the fan in the through hole and the electric heating mesh on the corresponding side of the support plate are started, which can facilitate the rapid drying and dehydration of the instruments in the disinfection basket. S6: After dehydration, the longitudinal component moves upward again, and then passes the transverse component away from the ultrasonic disinfection tank. After the contact rod and trigger rod on the moving seat move away from each other, the output end of the third motor drives the support plate to flip back. At the same time, under the action of the first spring, the rack moves in the opposite direction. The rack meshes with the gear, which also causes the connecting rod to flip back to its original position on the shaft frame. S7: After the disinfection basket returns to the connection point between the cabinet and the connecting frame, flip the limit rod away from the mating groove of the mating block, and it can be taken out. At this time, the disinfection and cleaning are completed.

[0008] Compared with the prior art, the beneficial effects of the present invention are: This invention facilitates the transport of the disinfection basket before and after disinfection through the design of the transverse and longitudinal components. The fixing component on the longitudinal component facilitates the installation of the disinfection basket. The cooperation between the transverse and flipping components allows the rotating component to flip during movement, enabling the operating component to spray, rinse, and dry the instruments in the disinfection basket above the ultrasonic disinfection tank. Simultaneously, when the transverse component moves away from the flipping component, it can automatically store the operating component on one side of the inner wall of the cabinet, without affecting the daily maintenance of the ultrasonic disinfection tank. Furthermore, by setting a placement rack on the inclined mesh plate of the disinfection basket and using limiting components, it is easy to adjust one end of different sizes of controlled instruments to the same level, facilitating the rinsing of the inner wall of the controlled instruments by the inclined jet of the ultrasonic disinfection tank. This process can complete the entire disinfection and rinsing of oral examination instruments without manual intervention, thus greatly facilitating the operation and use by oral healthcare personnel.

Insert blocks 17 are fixedly installed on both sides of the disinfection basket 2. The insert blocks 17 and the slots 16 are inserted and connected. The first sliding rod 8 installed in the mounting shell 501 allows the movable seat 504 to slide easily in the mounting shell 501. The sliding sleeves 7 on both sides of the movable seat 504 allow the upper end of the assembly frame 605 to slide vertically up and down on the outside of the movable seat 504. The insert blocks 17 on the disinfection basket 2 can be easily inserted into the slots 16 on the connecting frame 606.

[0015] The specific implementation method of this embodiment is as follows: After the disinfection basket 2 containing the instruments is placed on the connecting frame 606, the output end of the second motor 603 drives the second screw 602 to rotate between the bracket 601 and the movable seat 504, so that the movable rod 604 connected to the outer side of the second screw 602 drives the assembly frame 605 to slide upward. At the same time, the assembly frame 605 raises the disinfection basket 2 to a certain height through the connecting frame 606. Then, the output end of the first motor 502 of the transverse member 5 drives the first screw 503 to rotate, so that the movable seat 504 connected to the outer side of the first screw 503 slides towards the ultrasonic disinfection tank 13 until the disinfection basket 2 is above the ultrasonic disinfection tank 13. Then, the longitudinal member 6 moves down, so that the disinfection basket 2 is immersed in the disinfectant for disinfection and cleaning. Example 2

[0016] Please see Figures 3-4 This invention provides a technical solution: a disinfection device for oral examination instruments. This invention makes corresponding improvements to the technical problems mentioned in the background art.

A stop block 186 is fixedly installed on one side of the movable plate 187. The stop block 186 is movably connected to the inner side of the placement rack 4, utilizing the pull block 183. Pulling the lever 184 causes the movable plate 187 connected to the lever 184 to slide and compress the second spring 185. At the same time, the movable plate 187 causes the stop block 186 to separate from the placement rack 4. At this time, after moving the transfer case 181 to the appropriate position, the lever 183 is released, so that the stop block 186 is clamped on the placement rack 4 under the reset action of the second spring 185. At this time, all the controlled instruments can be adjusted to a horizontal row for easy subsequent cleaning. Both the placement rack 4 and the stop block 186 have several holes, allowing disinfectant to penetrate into the placement surface of the controlled instruments. The V-groove design of the placement rack 4 can limit the controlled instruments and prevent them from shifting during rinsing. The clamping surface of the stop block 186 is also compatible with the V-groove design of the placement rack 4 for easy clamping and limiting.

[0017] The specific implementation method of this embodiment is as follows: The oral examination instruments are laid flat on the inclined mesh plate 3 of the disinfection basket 2, while the controlled examination instruments are placed separately on the placement rack 4. According to the different lengths of the tubes, the pull block 183 is used to pull the pull rod 184, so that the movable plate 187 connected to the pull rod 184 slides and compresses the second spring 185. At the same time, the movable plate 187 drives the stop block 186 to separate from the placement rack 4. At this time, after moving the transfer shell 181 to the appropriate position, the pull block 183 is released, so that the stop block 186 is clamped on the placement rack 4 under the reset action of the second spring 185. At this time, one end of all the controlled instruments can be adjusted to be in a horizontal row for easy subsequent cleaning. Then, the disinfection basket 2 is inserted into the connecting rack 606, and then the limiting rod 154 is rotated on the limiting shaft 153 so that the limiting rod 154 is locked in the mating groove 152 of the mating block 151 of the disinfection basket 2.

[0019] The specific implementation of this embodiment is as follows: When the contact rod 505 on the movable seat 504 contacts the trigger rod 905, the limiting block 909 connected to the trigger rod 905 slides in the inner groove 907 and compresses the first spring 908. The limiting block 909 drives the dovetail block 903 to slide in the dovetail groove 904. At the same time, the rack 902 on the dovetail block 903 meshes with the transmission gear 901. The gear 901 is connected to the second connecting shaft 104, so that the connecting rod 103 flips on the shaft frame 101 through the first connecting shaft 102 and the second connecting shaft 104, so that it is directly above the ultrasonic disinfection tank 13. When disinfection... After cleaning, the longitudinal component 6 rises to the appropriate position so that the pipe head of the inclined flushing pipe 14 corresponds to the control instrument port at the placement rack 4 on the inclined mesh plate 3. At this time, the inclined flushing pipe 14 and the nozzle 121 are connected to the rinsing water, which can easily clean the control instruments and other instruments in the disinfection basket 2. After rinsing, the output end of the third motor 112 in the mounting hole 111 on the connecting rod 103 drives the support plate 115 to flip through the support block 114. Then, the fan 123 in the through hole 122 and the electric heating mesh 124 on the corresponding side of the support plate 115 are started, which can easily dry and dehydrate the instruments in the disinfection basket 2. A disinfection method for a dental examination instrument disinfection device, comprising the following specific steps: S1: First, place the oral examination instruments flat on the slanted mesh plate 3 of the sterilization basket 2, while the controlled examination instruments are placed separately on the placement rack 4. According to the different lengths of the tubes, use the pull block 183 to pull the pull rod 184, so that the movable plate 187 connected to the pull rod 184 slides and compresses the second spring 185. At the same time, the movable plate 187 drives the stop block 186 to separate from the placement rack 4. At this time, move the transfer shell 181 to the appropriate position and then release the pull block 183. The stop block 186 will be clamped on the placement rack 4 under the reset action of the second spring 185. At this time, the limit of one end of all the controlled instruments can be adjusted to be in a horizontal row for easy subsequent cleaning. S2: Then, insert the disinfection basket 2 into the connecting frame 606, and then use the limiting rod 154 to rotate on the limiting shaft 153 so that the limiting rod 154 is locked in the mating groove 152 of the mating block 151 of the disinfection basket 2. S3: Subsequently, the output end of the second motor 603 of the longitudinal member 6 drives the second screw 602 to rotate between the bracket 601 and the movable seat 504, so that the movable rod 604 connected to the outer side of the second screw 602 drives the assembly frame 605 to slide upward. At the same time, the assembly frame 605 raises the disinfection basket 2 to a certain height through the connecting frame 606. Immediately afterwards, the output end of the first motor 502 of the transverse member 5 drives the first screw 503 to rotate, so that the movable seat 504 connected to the outer side of the first screw 503 slides towards the ultrasonic disinfection tank 13 until the disinfection basket 2 is above the ultrasonic disinfection tank 13. Then, the longitudinal member 6 moves down, so that the disinfection basket 2 is immersed in the disinfectant for disinfection and cleaning. S3: During the movement of the movable seat 504, the contact rod 505 on the movable seat 504 contacts the trigger rod 905. At the same time, the limiting block 909 connected to the trigger rod 905 slides in the inner groove 907 and compresses the first spring 908. The limiting block 909 drives the dovetail block 903 to slide in the dovetail groove 904. At the same time, the rack 902 on the dovetail block 903 meshes with the transmission gear 901. The gear 901 is connected to the second connecting shaft 104, so that the connecting rod 103 rotates 90 degrees on the shaft frame 101 through the first connecting shaft 102 and the second connecting shaft 104, and is directly above the ultrasonic disinfection tank 13. S4: After disinfection and cleaning are completed, the longitudinal component 6 rises to the appropriate position so that the pipe head of the inclined flushing pipe 14 corresponds to the control instrument port at the placement rack 4 on the inclined mesh plate 3. At this time, the inclined flushing pipe 14 and the nozzle 121 are connected to the rinsing water, which can easily clean the control instruments and other instruments in the disinfection basket 2. S5: After rinsing, the output end of the third motor 112 in the mounting hole 111 on the connecting rod 103 drives the support plate 115 to flip through the support block 114. Then, the fan 123 in the through hole 122 and the electric heating net 124 on the corresponding side of the support plate 115 are started, which can facilitate the rapid drying and dehydration of the instruments in the disinfection basket 2. S6: After dehydration is completed, the longitudinal member 6 moves upward again, and then moves away from the ultrasonic disinfection tank 13 via the transverse member 5. After the contact rod 505 and trigger rod 905 on the moving seat 504 move away from each other, the output end of the third motor 112 drives the support plate 115 to flip back. At the same time, under the action of the first spring 908, the rack 902 moves in the opposite direction. The rack 902 meshes with the gear 901, which also causes the connecting rod 103 to flip back to its original position on the shaft frame 101. S7: After the disinfection basket 2 returns to the connection point between the cabinet 1 and the connecting frame 606, flip the limit rod 154 away from the mating groove 152 of the mating block 151, and it can be taken out. At this time, the disinfection and cleaning are completed.
