Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a disinfection cabinet for oral instruments. Background Art

[0002] Oral instruments play an important role in dental treatment. These instruments include probes, curettes, tooth extraction forceps, dental tweezers, dental hammers and chisels, root canal files, dental curettes, etc. Since oral instruments are in direct contact with the patient's oral tissue, they must go through a strict disinfection procedure to kill possible pathogenic microorganisms to ensure the safety and health of the patient.

[0003] Oral instrument sterilizers are mainly divided into ultraviolet sterilizers, ozone sterilizers, and high-temperature steam sterilizers according to different sterilization principles. Among them, high-temperature steam sterilizers use the bactericidal effect of high-temperature steam to sterilize oral instruments at high temperature and high pressure. It has the advantages of reliable sterilization effect and wide application range. However, it is necessary to pay attention to the temperature and pressure of the steam, as well as the high temperature resistance of the instruments.

[0004] When disinfecting oral instruments, you need to first clean the oral instruments to be disinfected, remove surface stains and residues, and then place them in the disinfection cabinet according to the specified placement. Then, according to the type of disinfection cabinet and the material of the oral instruments, select the appropriate disinfection program. For example, for ultraviolet disinfection cabinets, you can select appropriate irradiation time and intensity; for ozone disinfection cabinets, you can select appropriate ozone concentration and disinfection time; for high-temperature steam disinfection cabinets, you can select appropriate temperature and pressure, then turn on the power, press the power button, and start the disinfection program. Finally, after the disinfection is completed, you need to wait for the disinfection cabinet to cool down before taking out the instruments. When taking out the instruments, you need to pay attention to personal protection, wear gloves and other protective equipment, and avoid direct contact with high temperatures or harmful gases.

[0005] At present, when the existing technology is used to disinfect oral instruments, it is usually necessary to first soak the oral instruments in a cleaning agent to clean the surface dirt, then rinse them with running water, and finally sterilize them with pressure steam. However, soaking, rinsing and sterilization require personnel to operate in different equipment respectively, and the oral instruments need to be manually transferred multiple times, which is time-consuming and labor-intensive, and thus easily affects the efficiency of oral instrument disinfection. Therefore, it does not meet the existing needs. In this regard, we propose a disinfection cabinet for oral instruments. Summary of the invention

One ends of the two spray pipes 180 are respectively fixedly connected to the two first thread sleeves 183. A bellows 184 is arranged on the inner wall of the cabinet 100. The bellows 184 can be extended or shortened. The two ends of the bellows 184 are respectively connected to the other ends of the two spray pipes 180, and the middle part of the bellows 184 is connected to the flushing pipe 170.

[0040] A first gear 185 is rotatably provided on the inner wall of the cabinet 100, and a first rack 186 is fixedly installed on the outer side of the basket 140. The first rack 186 is gap-engaged with the first gear 185. Pulleys 187 are fixedly provided on the middle part of the first screw rod 182 and on the side of the first gear 185, respectively. The pulley 187 located on the side of the first gear 185 is coaxially arranged with the first gear 185, and a belt 188 is commonly sleeved between the two pulleys 187.

[0041] In this embodiment: the oral instruments are placed in the basket 140, and the winch 146 unwinds the traction rope 145 to drive the basket 140 to rise and fall. The basket 140 carrying the oral instruments descends under the action of gravity. During this process, the basket 140 first descends to the lower end of the spray pipe 180 through the gap between the two spray pipes 180, and then the first rack 186 is meshed with the first gear 185, so that the first gear 185 drives the pulley 187 on its side to rotate, and then the first screw rod 182 is rotated through the cooperation between the two pulleys 187 and the belt 188, and the first screw rod 182 is used in cooperation with the first wire sleeve 183, so that the two first wire sleeves 183 are close to each other, thereby driving the two spray pipes 180 to approach each other and be located above the basket 140, and the basket 140 descends to the bottom of the cabinet 100; The regulating valve 151 is turned to make the water inlet pipe 110 communicate with the soaking pipe 160 through the connecting hole 152, so that the cleaning liquid enters the bottom of the cabinet 100, and the oral instruments in the basket 140 are soaked and cleaned. After the soaking is completed, the cleaning liquid is discharged through the water outlet pipe 120, and the regulating valve 151 is turned again to make the water inlet pipe 110 communicate with the spray pipe 180 through the connecting hole 152, so that the clean water is sprayed on the oral instruments through the nozzle 181 on the spray pipe 180, and the residual cleaning liquid thereon is rinsed. Finally, the basket 140 carries the oral instruments up to the upper end of the cabinet 100, and the oral instruments are discharged through the steam pipe 130. Oral instruments are sterilized by spraying high-temperature and high-pressure steam. In summary, the immersion, rinsing and steam sterilization of oral instruments are centralized and integrated, and the manual operation and transfer process are reduced, thereby improving the efficiency of oral instrument disinfection, and solving as much as possible the problem that when oral instruments are sterilized in the prior art, it is usually necessary to first immerse the oral instruments in a cleaning agent to clean the dirt on the surface, then rinse with running water, and finally sterilize with pressure steam. However, the immersion, rinsing and sterilization require personnel to operate in different equipment respectively, and the oral instruments need to be manually transferred multiple times, which is time-consuming and labor-intensive, thus easily affecting the disinfection efficiency of the oral instruments.

Moreover, the faster the flow rate of the water flow, the faster the speed of driving the feeding screw 198 to rotate, so that the amount of added enzyme increases with the increase of water flow, so that the enzyme and clean water are installed in a certain ratio to prepare a cleaning solution of suitable concentration; After the soaking is completed, the cleaning liquid is discharged from the water outlet pipe 120, and the rotary drum 216 is rotated by hand. Through the meshing of the second gear 220 and the third gear 222, the third gear 222 drives the regulating valve 151 to rotate through the plug shaft 221, so that the end of the connecting hole 152 is connected with the flushing pipe 170, and the soaking pipe 160 is closed. At the same time, the rotating rotary drum 216 cooperates with the threaded rod 215 to make the threaded rod 215 pull the first wedge block 211 to move backward, and the first wedge block 211 and the two second wedge blocks 211 and 222 are connected. The coordinated use of the wedge blocks 212 enables the two second wedge blocks 212 to drive the two clamping pieces 217 to approach each other to clamp and fix the shaft 193, thereby preventing the shaft 193 from rotating, and making the feeding screw 198 stationary, so that clean water can be injected into the spray pipe 180 through the flushing pipe 170, and the oral instruments can be sprayed and rinsed through the nozzle 181. In summary, it is convenient to inject cleaning liquid or clean water into the cabinet 100 in a timely manner, so as to facilitate the rapid soaking and rinsing of the oral instruments, thereby further improving the efficiency of disinfection of the oral instruments.

[0048] Embodiment 3: This embodiment aims to solve the problem that the high-temperature and high-pressure steam sprayed from the steam pipe 130 diffuses in the inner cavity of the entire cabinet 100, which easily causes insufficient steam temperature and pressure, thereby easily affecting the disinfection effect of oral instruments. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 2 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13The inner wall of the cabinet 100 is also rotatably provided with a second screw rod 230, and the second screw rod 230 is the same as the first screw rod 182. Similarly, the outer side of the second screw rod 230 is respectively threadedly connected with two second thread sleeves 231, and the outer sides of the two second thread sleeves 231 are fixedly installed with support rods 232, and the ends of the support rods 232 are slidably inserted on the inner wall of the cabinet 100, and a blocking plate 233 is provided between the inner wall of the cabinet 100 and the adjacent support rods 232. The blocking plates 233 are all configured as accordion-type folding and retractable plates, that is, accordion plates similar to folding fans, which are formed by repeatedly folding a flat thin plate and can be stretched and compressed. The accordion plate is a multifunctional plate material with multiple properties such as sound insulation, sealing, fire prevention and retraction. The accordion plate is a commonly used prior art product and will not be described in detail here. One end of the blocking plate 233 is fixedly connected to the inner wall of the cabinet 100, and the other end of the blocking plate 233 is fixedly connected to the support rod 232.

[0049] See Fig. 9 and Fig.10 When the basket 140 is located above the baffle plate 233, the two support rods 232 approach each other and collide with each other, unfolding the baffle plate 233 so that the baffle plate 233 divides the space inside the cabinet 100 into two independent spaces, and the steam inlet end of the steam pipe 130 is connected to the upper part of the cabinet 100; when the basket 140 is located below the baffle plate 233 and the spray pipe 180, the two support rods 232 move away from each other and retract into the inner wall of the cabinet 100, compressing the baffle plate 233, releasing the separation effect of the baffle plate 233, and the end of the flushing pipe 170 is connected to the lower part of the cabinet 100, and the water outlet pipe 120 is connected to the bottom of the cabinet 100.

[0050] See Fig.13 A fourth gear 234 is fixedly installed at the end of the second screw rod 230, a second rack 235 is fixedly installed on the outside of the hook 143, the second rack 235 is intermittently meshed with the fourth gear 234, a slide 236 is fixedly installed on the outside of the first wire sleeve 183 and the second wire sleeve 231, a groove body for use with the slide 236 is opened on the inner side of the cabinet 100, and the slide 236 is slidably inserted in the groove body on the inner side of the cabinet 100.

[0051] In this embodiment: when the hook 143 descends together with the basket 140 and the slider 141, the hook 143 drives the second rack 235 to descend close to the fourth gear 234, and then the second rack 235 and the fourth gear 234 begin to mesh. At the same time, a sufficient distance is still maintained between the bottom of the basket 140 and the blocking plate 233. The second rack 235 and the fourth gear 234 are meshed to drive the second screw rod 230 to rotate. Through the cooperation of the second screw rod 230 and the second wire sleeve 231, the second wire sleeve 231 drives the support rod 232 to move away from each other, so that the blocking plate 233 is retracted into the side wall of the cabinet 100 to avoid hindering the descent of the basket 140. When the basket 140 rises from the bottom of the cabinet 100, similarly to the above, the second rack 235 and the fourth gear 234 are meshed again, and the second screw rod 230 and the second screw sleeve 231 are used in coordination, so that the blocking plate 233 is unfolded, so that when the basket 140 is located in the upper part of the cabinet 100, the blocking plate 233 separates the cabinet 100 into two independent spaces, the upper and lower spaces, so that the high-temperature and high-pressure steam sprayed from the steam pipe 130 is concentrated in the upper inner cavity of the cabinet 100, so that the steam maintains a sufficient temperature and pressure, thereby improving the disinfection effect on the oral instruments in the basket 140.
