Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a water irrigation auxiliary device for a dental treatment table. Background Technology

[0002] Dental treatment units are core equipment in modern dental care, equipped with complex water supply systems to provide water for the instruments. However, this water system has long been plagued by serious microbial contamination, posing a significant potential risk of cross-infection during dental treatment.

[0003] Contamination in the dental unit waterline (DUWL) primarily originates from biofilm. Because the water pipes are typically long and narrow, and the water flow is stagnant during breaks in use, an environment conducive to bacterial attachment and proliferation is created. Bacteria adhere to the pipe walls and secrete extracellular polymers, forming a biofilm. Once formed, this biofilm is extremely difficult to remove completely and continuously releases free bacteria into the water flow. When dentists use treatment instruments, this highly contaminated water comes into direct contact with the patient's oral tissues, especially during invasive procedures such as tooth extractions and periodontal treatments, greatly increasing the risk of infection.

[0004] In existing technologies, to control DUWL contamination, the water system is typically flushed before and after each treatment session. However, this method relies heavily on the water pressure of the municipal water supply network, which often lacks sufficient flow rate and velocity to effectively shear and scour the firmly attached biofilm. This is especially true for the slender internal tubing of instruments such as handpieces and scalers connected to the end of the dental chair, where routine flushing is almost ineffective.

[0005] Therefore, existing methods cannot effectively and thoroughly solve the problem of biofilm contamination in the water channels of dental treatment units. There is an urgent need for a water channel rinsing auxiliary device capable of active, powerful, and targeted flushing, and linked to the operating status of the treatment unit, to control bacterial growth at its source. Summary of the Invention

[0006] The purpose of this invention is to address the problems existing in the prior art by providing an auxiliary device for rinsing the water system of a dental treatment unit. This device uses an independent water storage bottle to supply water, avoiding initial contamination from direct use of municipal tap water. Compared to existing technologies that rely on natural liquid flow for water delivery, this device uses compressed air for pressurized rinsing, more effectively flushing away biofilm and plaque adhering to the water pipe walls. Simultaneously, the water storage bottle facilitates the injection of disinfectant, enabling regular disinfection of the entire water system, thereby effectively reducing biofilm contamination and controlling the risk of cross-infection. This invention also achieves automatic control of the water supply to the dental treatment unit through sensor and controller linkage, which not only facilitates operation but, more importantly, allows for zoned rinsing of different water branches, ensuring rinsing effectiveness while conserving resources.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Both ends of each connector are provided with annular elastic elements.

[0012] Furthermore, the connecting member includes a bearing, the inner wall of the bearing of the two connecting members is respectively fixed to the outer wall of the air inlet pipe and the water outlet pipe, the outer wall of the bearing is fixed to a sleeve, and the inner wall of the two sleeves is respectively threaded to the outer wall of the air inlet mounting member and the water outlet mounting member.

[0013] Furthermore, an annular groove is formed on the outer wall of the sleeve, and the annular elastic elements of the two protective mechanisms near the end of the connector are respectively embedded in the two grooves.

[0014] Furthermore, the portion of the protective mechanism embedded in the groove is limited by a limiting rope.

[0015] Furthermore, an annular groove 1 is formed on the outer wall of the air intake mounting component, and the annular elastic element of the protection mechanism installed on the air intake mounting component near one end of the air intake mounting component is embedded in the groove 1; an annular groove 2 is formed on the outer wall of the water outlet mounting component, and the annular elastic element of the protection mechanism installed on the water outlet mounting component near one end of the water outlet mounting component is embedded in the groove 2.

[0030] The technical solution of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Example 1:

[0032] Please see Figure 1-9 A water rinsing auxiliary device for a dental treatment unit includes a water storage bottle 2 and water pipes. The water storage bottle 2 is connected to the dental treatment unit via the water pipes. The water storage bottle 2 is also connected to an air supply pipe. An air inlet pipe 311 is installed at one end of the air supply pipe and extends into the water storage bottle 2. The end of the air supply pipe away from the water storage bottle 2 is connected to an air compressor 3. The water pipes include a main pipe 41, and a mouthwash station water supply pipe 42 and a dental chair tail line 43, which are respectively connected to the main pipe 41. The air supply pipe, the main pipe 41, and the mouthwash station water supply pipe 42 are connected to the main pipe 41. Both the oral cavity water supply pipe 42 and the dental chair tail line 43 are equipped with valves for controlling opening and closing. The main pipe 41 is connected to the water outlet pipe 411 at the end near the water storage bottle 2. The water outlet pipe 411 extends into the bottom of the water storage bottle 2. The instrument table 13 is installed on the dental treatment table. The controller is installed on the instrument table 13. Several dental treatment instruments are installed on the instrument table 13. The dental chair tail line 43 includes different water branches, each branch connecting to a different dental treatment instrument. The air compressor, several valves, and several dental treatment instruments are all electrically connected to the controller.

[0033] In one embodiment, the dental treatment device includes a scaler, a handpiece, and a three-way gun. A controller controls the opening and closing of the water channel branches of the scaler, handpiece, and three-way gun. Sensors are provided on the scaler, handpiece, and three-way gun. When the scaler, handpiece, and three-way gun are picked up from the instrument table 13, the controller opens the water channel branches of the scaler, handpiece, and three-way gun. When the scaler, handpiece, and three-way gun are placed on the instrument table 13, the controller closes the water channel branches of the scaler, handpiece, and three-way gun.

[0034] It should be noted that a mouthwash stand body 12 is also installed on the dental treatment table, and the water supply pipe of the mouthwash stand body 12 is connected to the mouthwash stand water supply pipe 42.

[0035] It should be noted that the top of the body 21 of the water storage bottle 2 is provided with a water inlet 211, which is used to fill the water storage bottle 2 with water. The water inlet 211 is closed when the water storage bottle 2 is in use, and the closing method is not limited. In one embodiment, a sealing solution is provided by using a water bottle cap and a threaded connection between the cap and the water storage bottle 2. It should also be noted that all equipment used in the medical device has undergone medical sterilization. The medical sterilization methods are existing technologies well known to those skilled in the art and will not be described in detail here.

[0036] The device provided by this invention uses an air compressor 3 to compress air, which then pumps pure water or disinfectant from a water storage bottle 2 into the water pipe, thereby achieving dental cleaning and water pipe flushing.

[0037] In actual use, the water storage bottle 2 is pre-filled with purified water or disinfectant. The controller opens the valve on the gas supply pipeline (i.e., the air inlet valve of the water storage bottle) and starts the air compressor 3. Compressed air enters the top space inside the water storage bottle 2 through the air inlet pipe 311. Under the action of air pressure, the liquid in the water storage bottle 2 is forced out through the water outlet pipe 411 that extends into the bottom of the water storage bottle 2 and enters the main pipeline 41.

[0038] When dental cleaning or water pipe cleaning is required for the mouthwash stand body 12, the controller controls the opening of the valve of the main pipe 41 (i.e., the water outlet valve of the water storage bottle) and the valve of the mouthwash stand water supply pipe 42 (i.e., the mouthwash stand water supply valve). The liquid enters the mouthwash stand water supply pipe 42 through the main pipe 41 and then enters the mouthwash stand body 12.

[0039] The mouthwash station itself is a product of existing technology, including a mouthwash station faucet and a sink. The mouthwash station faucet is connected to the mouthwash station water supply pipe 42, and the sink is connected to the medical wastewater pipe, which will not be described in detail here.

[0040] When dental cleaning or water pipe cleaning of the dental treatment instrument is required, the controller opens the valve of the main pipe 41 (i.e., the water outlet valve of the storage bottle) and the valve of the dental chair tail line 43 (i.e., the water supply valve of the dental chair tail line), allowing liquid to enter the dental chair tail line 43. The dental chair tail line 43 is divided into different water branches, which are connected to the scaler, handpiece, and three-way nozzle, respectively. The controller determines the connection status of the scaler, handpiece, and three-way nozzle to the instrument table 13 based on the sensors, and controls the opening and closing of the water branches of the scaler, handpiece, and three-way nozzle to the instrument table 13 accordingly. When the operator picks up the dental treatment instrument from the instrument table 13, the sensor sends a signal to the controller, which automatically opens the valve of the corresponding water branch of the dental treatment instrument to provide water; when the dental treatment instrument is placed back on the instrument table 13, the controller closes the corresponding water branch valve to stop the water supply.

[0041] The device provided by this invention uses an independent water storage bottle 2 to supply water, avoiding the initial pollution caused by directly using municipal tap water. Compared with the existing technology that relies on the natural flow of liquid for water delivery, this device uses compressed air for pressurized flushing, which more effectively washes away the biofilm and bacterial plaque attached to the water pipe wall. At the same time, the water storage bottle 2 provided by this device facilitates the injection of disinfectant, thereby regularly disinfecting the entire water pipeline, effectively reducing biofilm pollution in the water pipeline and controlling the risk of cross-infection.

[0042] This invention also achieves automatic control of the water supply for the dental treatment instrument through the linkage of sensors and controllers. This not only facilitates operation but, more importantly, enables zoned rinsing of different water branches, ensuring rinsing effectiveness while saving resources.

[0043] A liquid level sensor is installed inside the water storage bottle 2. An overflow valve 212 is provided on the water storage bottle 2. The overflow valve 212 is connected to the water storage bottle 2. The height inside the water storage bottle 2 is lower than that of the air inlet pipe 311.

[0044] During normal operation, the air compressor 3 starts, and compressed air enters the top space of the water storage bottle 2 through the air inlet pipe 311. The liquid level in the water storage bottle 2 is lower than the inlet of the air inlet pipe 311. The air inlet pipe 311 only delivers gas and does not come into contact with the liquid. Under the action of air pressure, the liquid in the water storage bottle 2 is forced out from the bottom outlet pipe 411. When the liquid level in the water storage bottle 2 rises abnormally, since the position of the overflow valve 212 is lower than the air inlet pipe 311, the liquid level first submerges the overflow valve 212. The liquid level sensor detects the abnormal liquid level, and the controller opens the overflow valve 212. The liquid or gas-liquid mixture is discharged from the overflow valve 212, preventing the liquid level from continuing to rise to the height of the air inlet pipe 311.

[0045] This device ensures that when the liquid level exceeds the set value, the liquid is discharged through the overflow valve 212, preventing liquid from flowing back into the air intake pipe 311 and the air compressor 3, by setting the height of the overflow valve 212 to be lower than that of the air intake pipe 311.

[0046] Example 2:

[0047] Please see Figure 1-9 According to Embodiment 1, a water rinsing auxiliary device for a dental treatment table includes a water storage bottle 2 comprising a bottle body 21. An air inlet mounting component 22 and a water outlet mounting component 23 are installed on the top of the bottle body 21. An air inlet 221 is provided on the air inlet mounting component 22, and an air inlet pipe 311 extends into the bottle body 21 by inserting into the air inlet 221. A water outlet 231 is provided on the water outlet mounting component 23, and a water outlet pipe 411 extends into the bottle body 21 by inserting into the water outlet 231. The outer walls of the air inlet pipe 311 and the water outlet pipe 411 are slidably connected to the inner walls of the air inlet 221 and the water outlet 231, respectively.

[0048] The design of the outer walls of the air inlet pipe 311 and the water outlet pipe 411 slidingly connected to the inner walls of the air inlet 221 and the water outlet 231 respectively allows the air supply pipe and the main pipe 41 to be detachably connected to the air inlet mounting component 22 and the water outlet mounting component 23, thus facilitating the separate handling of the water storage bottle 2 after disassembly. At the same time, this device can choose to use multiple water storage bottles 2 to store water together. After the flushing fluid in the water storage bottle 2 in use is used up, other water storage bottles 2 can be quickly replaced, avoiding the need to frequently add flushing fluid to the water storage bottle 2 during medical treatment.

[0049] Both the air inlet mounting component 22 and the water outlet mounting component 23 have mounting threads on the upper part of their outer walls. Both the air inlet mounting component 22 and the water outlet mounting component 23 are connected to two different connectors 27 through the mounting threads. One end of each of the two connectors 27 is installed on the outer wall of each connector. The other end of each of the two protection mechanisms 24 is connected to the air inlet mounting component 22 and the water outlet mounting component 23 respectively. Both ends of the protection mechanism 24 are provided with annular elastic elements.

[0050] One end of each of the two protective mechanisms 24 is connected to the outer wall of the connector 27 via an annular elastic element, and the other end is connected to the air inlet mounting 22 or the water outlet mounting 23 via an annular elastic element, thereby forming a closed auxiliary connection between the connector 27 and the air inlet mounting 22 or the water outlet mounting 23.

[0051] The connector 27 includes a bearing 271. The inner walls of the bearings 271 of the two connectors 27 are respectively fixed to the outer walls of the air inlet pipe 311 and the water outlet pipe 411. The outer walls of the bearings 271 are both fixed to the sleeves 272. The inner walls of the two sleeves 272 are respectively threaded to the outer walls of the air inlet mounting component 22 and the water outlet mounting component 23.

[0052] The outer walls of the air inlet pipe 311 and the water outlet pipe 411 are fixed to the inner ring of the bearing 271. That is, the air inlet pipe 311 and the water outlet pipe 411 are integral with the inner ring of the bearing 271. The outer ring of the bearing 271 is fixed to the sleeve 272. The sleeve 272 has internal threads for connecting to the mounting threads on the air inlet mounting component 22 or the water outlet mounting component 23.

[0053] When it is necessary to connect the air inlet pipe 311 or the water outlet pipe 411 to the water storage bottle 2, the operator rotates the outer ring of the bearing 271 and the sleeve 272 to connect the connector 27 and the air inlet mounting component 22 or the water outlet mounting component 23, thereby avoiding the phenomenon of twisting and entanglement of the air transmission pipe or the main pipe 41 during the installation process.

[0054] An annular groove 273 is formed on the outer wall of the sleeve 272, and the annular elastic elements of the two protective mechanisms 24 near the end of the connector 27 are respectively embedded in the two grooves 273.

[0055] The annular elastic element at the end of the protective mechanism 24 is directly embedded in the annular groove 273 on the outer wall of the sleeve 272, so that the connection point of the protective mechanism 24 is installed at the groove 273, preventing the end of the protective mechanism 24 from sliding on the outer wall of the sleeve 272. The annular elastic element undergoes elastic deformation when embedded in the groove 273, and when installed in place, the elastic force of the annular elastic element makes it fit tightly in the groove 273.

[0056] The portion of the protective mechanism 24 embedded in the groove 273 is limited by the limiting rope 26.

[0057] The limiting rope 26 is wrapped around the groove 273, binding the annular elastic element at the end of the protection mechanism 24 into the groove 273, thereby improving the stability of the connection and preventing the protection mechanism 24 from accidentally falling off the connector 27.

[0058] An annular groove 222 is formed on the outer wall of the air intake mounting component 22, and the annular elastic element of the protective mechanism 24 installed on the air intake mounting component 22 near one end of the air intake mounting component 22 is embedded in the groove 222; an annular groove 232 is formed on the outer wall of the water outlet mounting component 23, and the annular elastic element of the protective mechanism 24 installed on the water outlet mounting component 23 near one end of the water outlet mounting component 23 is embedded in the groove 232.

[0059] The annular elastic element at the other end of the protective mechanism 24 is embedded in slot 222 or slot 232, so that the other connection point of the protective mechanism 24 is installed in slot 222 or slot 232, preventing the other end of the protective mechanism 24 from sliding on the outer wall of the air inlet mounting component 22 or the water outlet mounting component 23. The annular elastic element undergoes elastic deformation when embedded in slot 222 or slot 232. When installed in place, the elastic force of the annular elastic element makes it fit tightly in slot 222 or slot 232.

[0060] The portions of the two protective mechanisms 24 embedded in slot one 222 and slot two 232 are both limited by different retaining rings 25.

[0061] The retaining ring 25 confines the annular elastic element at the end of the protection mechanism 24 within the retaining groove 222 and the retaining groove 232, thereby improving the stability of the connection and preventing the protection mechanism 24 from accidentally falling off the air inlet mounting 22 or the water outlet mounting 23.

[0062] Preferably, the retaining ring 25 is C-shaped and made of flexible material, so that the retaining ring 25 can be inserted or removed into the required position by means of deformation through its elastic opening and closing ability, so as to achieve quick loading and unloading. At the same time, the material's own elasticity is used to ensure tight fixation, making the operation convenient and the connection reliable.

[0063] The protection mechanism 24 includes a flexible element 243. The annular elastic elements at the upper and lower ends of the protection mechanism 24 are respectively an upper elastic ring 241 and a lower elastic ring 242. The upper elastic ring 241 and the lower elastic ring 242 are connected by the flexible element 243. The flexible element 243 is cylindrical, and the length of the flexible element 243 matches the length of the air inlet pipe 311 and the water outlet pipe 411.

[0064] In one embodiment, the flexible element 243 is made of a medical film and unfolds into a cylindrical shape.

[0065] In one embodiment, the upper elastic ring 241 and the lower elastic ring 242 are made of medical rubber bands.

[0066] When the water storage bottle is installed normally, the upper elastic rings 241 of the two protection mechanisms 24 are installed on the two connectors 27 respectively through the grooves 273 on the sleeve 272 and the limiting rope 26. The two lower elastic rings 242 are installed on the slots 222 and 232 of the air inlet and water outlet installation parts 22 and 233 respectively.

[0067] Taking the protection mechanism 24 connecting the air intake mounting component 22 as an example, since the connector 27 is tightly connected to the air intake mounting component 22 and the two are closest, the flexible component 243 is in a folded and retracted state at this time. The protection mechanism 24 connecting the water outlet mounting component 23 is similar.

[0068] When the water storage bottle 2 needs to be disassembled, taking the protective mechanism 24 connecting the air inlet mounting piece 22 as an example, the connector 27 is rotated to pull it off the air inlet mounting piece 22. The distance between the upper elastic ring 241 and the lower elastic ring 242 gradually increases, causing the flexible piece 243 to be stretched and unfolded from its folded state, forming a cylindrical protective shield. The upper elastic ring 241 at the upper end of the flexible piece 243 connects to the connector 27, and the lower elastic ring 242 at the lower end of the flexible piece 243 connects to the air inlet mounting piece 22, thereby forming a closed channel isolated from the external environment inside the protective mechanism 24. The pulled-out air inlet pipe 311 is located inside the unfolded flexible piece 243, avoiding any contact with the external environment. The protective mechanism 24 connecting the water outlet mounting piece 23 works similarly.

[0069] When installing a new water storage bottle 2, taking the protective mechanism 24 connecting the air inlet mounting piece 22 as an example, the air inlet pipe 311 is located inside the unfolded flexible part 243. The operator clamps the lower elastic ring 242 onto the air inlet mounting piece 22 of the water storage bottle 2 to be replaced, and then inserts the air inlet pipe 311 into the water storage bottle 2 through the air inlet 221 under the cover of the flexible part 243. The entire docking process is completed inside the flexible part 243, ensuring the sterility of the air inlet pipe 311. Tightening the connector 27 reduces the distance between the upper elastic ring 241 and the lower elastic ring 242, and the flexible part 243 is compressed back into a folded state. The protective mechanism 24 connecting the water outlet mounting piece 23 works similarly.

[0070] This invention, through the physical barrier formed by the unfolded flexible component 243, ensures that the air inlet pipe 311 and water outlet pipe 411, which are in direct contact with the liquid, do not come into contact with surrounding medical devices, patients, or operators during the entire replacement process of the water storage bottle 2. This directly prevents contaminants from entering the entire system pipeline and greatly reduces the risk of cross-infection caused by contamination of the medical water for patients.

[0071] The design of the protection mechanism 24 also avoids the cumbersome disinfection process of the air inlet pipe 311 and water outlet pipe 411 after each replacement of the water storage bottle 2, achieving plug-and-play functionality, minimizing the time cost and complexity of replacement operations, and making regular water system maintenance easier to perform.

[0072] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
