Description

Technical Field

[0001] This invention relates to the field of oral treatment equipment technology, specifically to a sterilized comprehensive oral treatment device. Background Technology

[0002] In the field of oral healthcare, comprehensive dental treatment equipment is a core tool for conducting diagnosis and treatment, and its performance directly affects treatment safety, patient comfort, and treatment efficiency. However, existing comprehensive dental treatment equipment has gradually revealed several shortcomings during long-term use, making it difficult to meet the clinical demands for high safety and high comfort. These shortcomings are specifically manifested in the following aspects: Regarding the supply of water and air, the high-pressure air source (to drive the handpiece) and sterile water source (for rinsing and cooling) required for dental handpieces are mostly provided by independent devices (such as separate air compressors and water purifiers). This results in large equipment footprints and complex piping, increasing the difficulty of treatment space layout and making it prone to air and water leaks due to poor sealing at pipe connections. Furthermore, the maintenance cost of independent systems is high. Secondly, some devices only use single-stage filtration for air purification (e.g., only removing large particulate impurities), without deep treatment of oil mist, moisture, and microorganisms in the compressed air. This can easily lead to wear on the dental handpiece turbine components (oil mist contamination) or cross-infection due to microbial residue. In addition, the lack of an air storage and pressure stabilization structure means that frequent start-stop of the air compressor can cause fluctuations in air source pressure, affecting the stability of handpiece operation (e.g., fluctuating speed), and consequently affecting treatment accuracy. Existing water treatment methods mostly employ "single-stage filtration + single sterilization." Modes (such as activated carbon filtration only or ultraviolet sterilization only) are insufficient to completely remove heavy metals, microbial spores and other contaminants from tap water, resulting in a low rate of sterile water compliance. At the same time, most water storage devices are single-tank designs, which can easily lead to water outages when changing or replenishing water, causing treatment interruptions. Some devices use chemically synthesized disinfectant solutions (such as high-concentration sodium hypochlorite), which pose a risk of residual disinfectant and can irritate the patient's oral mucosa.

[0003] Regarding treatment safety, the air intake structure of the dental cabinets is mostly cylindrical, lacking anti-pollution design. External dust and water droplets can easily enter the cabinet directly, contaminating air purification and water treatment components and shortening the equipment's lifespan. The air outlets lack noise reduction treatment, and the noise generated by the fan operation and airflow far exceeds the ≤55dB quiet standard for dental treatment rooms, easily causing patient anxiety and affecting the treatment experience. Furthermore, the connection between the dental handpiece and tubing lacks an anti-backflow structure, allowing saliva and blood from the mouth to flow back along the tubing after treatment, contaminating the air and water system and increasing the risk of cross-infection. The lack of patient vital sign monitoring means that when patients experience sudden increases in blood pressure or abnormal heart rate due to tension or pain, doctors may not be able to detect it in time, easily leading to medical safety accidents. Dental chairs are mostly fixed support structures, unable to adjust their support shape according to the patient's body shape (such as height, weight, and waist curve), easily causing neck, shoulder, and lower back fatigue during prolonged treatment, resulting in poor comfort.

[0004] In terms of operation and control, the existing equipment relies on independent instruments for monitoring air and water flow and pressure, which require manual inspection one by one and cannot be centrally monitored and controlled; the electromagnetic control valves are decentralized, which is cumbersome to operate and makes it difficult to achieve precise matching of air and water parameters (such as the synchronization of the mobile phone operation and the flushing water flow), affecting the treatment efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a sterilization-based comprehensive oral treatment device that has achieved multi-dimensional technological improvements.

[0006] This invention is achieved through the following technical solution: a sterile oral comprehensive treatment device, including a dental chair, a treatment table on one side of the dental chair, a dental handpiece mounted on the treatment table, and an integrated air-water purification box that provides a high-pressure air source and sterile water for the dental handpiece. The integrated air-water purification box includes an externally enclosed box body, an air purification system and a water treatment system installed inside the box body, an air compressor fixedly installed in the lower part of the box body, and an air outlet pipe of the air compressor connected to the air purification system. The air purification system connects the purified compressed air to the water treatment system and the dental handpiece respectively through an air supply pipe, serving as the power source for the water treatment system to output purified water, and the power source and air source for the operation of the dental handpiece. The water supply pipe of the water treatment system extends out of the box body and connects to the dental handpiece, providing a clean water source for the dental handpiece. An air inlet pipe for supplying air to the box body and an air outlet for outputting air from the box body are also provided in the upper part of the box body.

[0007] The working principle of this technical solution is to achieve the aseptic operation requirements of dental handpieces through an integrated air-water purification box. The air compressor in the integrated air-water purification box generates initial compressed air, serving as the power and air source for the entire system. This compressed air first enters the air purification system to remove impurities, moisture, and microorganisms, achieving aseptic standards. The purified compressed air is output in two paths: one path directly connects to the dental handpiece, serving as the power and air source for its high-speed operation; the other path is delivered to the water treatment system, providing pressure for the output of purified water. The water treatment system connects to an external water source and treats the water into sterile water through processes such as filtration and sterilization. Using the compressed air from the air purification system as power, the sterile water is pressurized and delivered to the dental handpiece through a water pipe, meeting the rinsing and cooling requirements during treatment. The air inlet pipe at the top of the box supplies clean air into the box, while the outlet simultaneously discharges air from the box, forming an air circulation system. This prevents the air inside the box from becoming damp and breeding microorganisms, while also providing a stable working environment for components such as the air compressor and purification system, preventing damage from moisture.

[0008] To better realize the present invention, the air purification system further includes an air purification cylinder and an air storage cylinder. The air inlet of the air purification cylinder is connected to the air outlet pipe of the air compressor that outputs compressed air. The air purification cylinder is connected to the water treatment system through a first air supply pipe, using the purified air to provide power to the water treatment system to output purified water. The air purification cylinder is connected to the air storage cylinder through a second air supply pipe. The air storage cylinder receives and stores the purified air. The air storage cylinder outputs the stored purified air through a third air supply pipe. The third air supply pipe extends out of the housing and connects to the dental handpiece mounted on the treatment table, providing power and air source for the operation of the dental handpiece.

[0009] To better realize the present invention, the water treatment system further includes a filtration mechanism consisting of at least three filter elements connected in series, a dosing tank, a sterilization tank, and at least two water storage tanks; the inlet of the filtration mechanism is connected to an external tap water source via an inlet pipe, and the outlet of the filtration mechanism is connected to the bottom inlet of the sterilization tank via a first water supply pipe; the filtered water enters the sterilization tank from the bottom inlet via the first water supply pipe; the dosing tank is connected to the sterilization tank via a dosing pipe, and the dosing pipe is also equipped with a dosing device for... The disinfectant solution in the dosing tank is injected into the peristaltic pump in the sterilization tank; the water outlet at the top of the sterilization tank is connected to a number of second water pipes matching the number of water storage tanks, and each second water pipe is connected to the top of an independent water storage tank. The sterilized water in the sterilization tank enters the corresponding water storage tank through the water inlet at the top of the water storage tank via the second water pipe; each water storage tank is provided with an air inlet at the top connected to an air supply pipe, and the water outlet at the bottom is connected to a dental handpiece via a third water supply pipe extending out of the tank body to provide the dental handpiece with sterilized water.

[0010] To better realize the present invention, the disinfectant solution in the dosing tank is an aqueous solution of Jatropha curcas leaf extract. The disinfection and sterilization tank includes a tank body with an inlet at the bottom and an outlet at the top. At least one layer of metal sterilization mesh is also provided inside the tank body, which is placed between the inlet and outlet of the tank body. The metal sterilization mesh is made of at least one of copper and zinc, or a copper-zinc alloy. A disinfection and sterilization lamp capable of irradiating ultraviolet light onto the tank body is provided on the top of the tank body.

[0011] To better realize the present invention, an electrical mounting plate is further provided on the top of the box, and an integrated control circuit is installed on the electrical mounting plate. Each pipe inside the box is equipped with an electromagnetic control valve, and the electromagnetic control valves are electrically connected to the integrated control circuit. A control panel is also provided at the front end of the box. The control panel monitors the air and water flow and air pressure in the pipes through the integrated control circuit, combined with flow meters and pressure gauges, and feeds the data back to the control panel, thereby realizing the control of the electromagnetic control valves on all pipes.

[0012] To better realize the present invention, the air inlet pipe provided on the upper part of the box is a vertical curved pipe. One end of the air inlet pipe is installed on the upper part of the inner side of the box and communicates with the outside. The other end of the air inlet pipe is vertically open downward and communicates with the inside of the box. An exhaust fan that draws outside air into the box is also installed in the middle of the air inlet pipe. A screen is also provided at the inlet of the air inlet pipe.

[0013] To better realize the present invention, a silencer is further installed at the air outlet on the upper part of the housing.

[0014] To better realize the present invention, a pipe check valve is further provided at the end of the dental handpiece connected to the water pipe and the air pipe.

[0015] To better realize the present invention, the treatment table is further equipped with a life monitoring system. The life monitoring system can monitor the patient's vital signs parameters in real time and provide feedback to the doctor. When the patient's vital signs are unstable, it will issue an early warning and cut off the air and water supply to the dental handpiece, stopping the operation of the dental handpiece.

[0016] To better realize the present invention, the dental chair is further provided with multiple independently adjustable airbags, which are distributed in the backrest, seat cushion and headrest of the chair, and are used to change the support shape of the chair by adjusting the inflation volume of the airbags.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The present invention integrates an air compressor, an air purification system and a water treatment system into one unit through an air-water integrated purification box, replacing the traditional decentralized device, greatly reducing the equipment footprint and saving space compared to traditional equipment; at the same time, it simplifies the pipeline connection, requiring only 2-3 main pipes to connect the dental handpiece, reducing the risk of leakage, and centralized maintenance can reduce maintenance workload and cost; (2) In this invention, the air purification cylinder achieves deep purification of compressed air through multi-stage filtration and sterilization, removes oil mist and microorganisms, and avoids wear and cross-infection of the handpiece turbine; the air storage cylinder can store the purified compressed air, realize on-demand output, avoid pressure fluctuations caused by frequent start and stop of the compressor, ensure stable rotation speed of the dental handpiece, and improve treatment accuracy. (3) In this invention, the water treatment system adopts a filtration mechanism to achieve deep pretreatment of raw water, combined with Jatropha curcas leaf extract for natural disinfection without residue, and a synergistic sterilization mode with a metal sterilization mesh (copper / zinc / copper-zinc alloy) that releases metal ions to assist sterilization, increasing the sterilization rate to 99.999%, far exceeding the traditional single sterilization method, and the natural extract avoids chemical residue irritation; the backup design with at least two water storage tanks for alternating use can ensure a continuous supply of sterile water (each tank has a volume of 5L, which can meet 30 minutes of continuous treatment), completely solving the water shortage problem of the traditional single tank design; and the power for water delivery comes from the clean air provided by the air purification system, further avoiding contamination during the water treatment process, and achieving complete elimination of bacteria and other toxic and harmful substances; (4) The tube check valve at the end of the dental handpiece tube in this invention can effectively prevent oral secretions from flowing back along the tube, avoid air and water system contamination, and reduce the risk of cross-infection; the life monitoring system of the treatment table monitors the patient's heart rate, blood pressure and other vital signs in real time, and automatically warns and cuts off the air and water supply of the dental handpiece when abnormal, forcibly stopping the treatment, providing emergency protection for the patient's sudden condition (such as fainting, sudden rise in blood pressure) and improving the safety of diagnosis and treatment. (5) The integrated control circuit and control panel on the top of the box in this invention realize centralized monitoring and precise control of air and water flow and pressure. Furthermore, the dental handpiece foot switch is linked by the electromagnetic control valve.

Thus, the terms "first" and "second" are limited to descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly including one or more of the feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example 1: The main structure of this embodiment is as follows: Figures 1-3 As shown, the dental chair includes a dental chair 1, a treatment table 2 is provided on one side of the dental chair, a dental handpiece 3 is installed on the treatment table 2, and an integrated air-water purification box 4 that provides a high-pressure air source and sterile water for the dental handpiece 3. The structure of the integrated air-water purification box 4 is as follows. Figure 2 As shown, the device includes an externally enclosed housing 41. An air purification system 42 and a water treatment system 43 are installed inside the housing 41. An air compressor 44 is fixedly installed in the lower part of the housing 41. The air compressor 44's compressed air outlet pipe is connected to the air purification system 42. The air purification system 42 transmits purified compressed air through air pipes to the water treatment system 43 and the dental handpiece 3, respectively, serving as the power source for the water treatment system 43 to output purified water and for the dental handpiece 3 to operate. The water supply pipe of the water treatment system 43 extends out of the housing 41 and connects to the dental handpiece 3, providing a clean water source for the dental handpiece 3. An air inlet pipe 45 for supplying air to the housing 41 and an air outlet for outputting air from the housing 41 are also provided on the upper inner side of the housing 41.

[0024] The specific implementation process is as follows: the dental chair 1 is placed in the center of the treatment area, the treatment table 2 is fixed on one side of the dental chair and used to place the dental handpiece 3 and other instruments. The air-water integrated purification box 4 is installed on the floor next to the treatment table to avoid occupying the treatment operation space. The box body 41 is made of 304 stainless steel to ensure airtightness and corrosion resistance.

[0025] The air compressor 44 is an oil-free, silent air compressor with an exhaust pressure set at 0.7MPa~0.8MPa. It is installed at the bottom of the housing, with anti-vibration pads added to reduce noise. The air purification system 42 receives the high-pressure air from the air compressor 44 and purifies and disinfects it. The purified high-pressure air is used as the power source for the water treatment system 43 to output purified water, as well as for the operation of the dental handpiece 3. The water treatment system 43 receives tap water, filters and disinfects it, and uses the clean air provided by the air purification system 42 as power to ultimately provide clean water for the dental handpiece 3. The air supply pipe is made of food-grade PU tubing, and the water supply pipe is made of food-grade PE tubing.

[0026] The bottom of the housing 41 has four lifting seats 49 and casters 410 with brakes at its four corners. The lifting seats 49 are for securing the housing 41 of the integrated air-water purification box 4, and the casters 410 are for facilitating the movement of the entire integrated air-water purification box 4. In actual use, the lifting seats 49 are raised first, and then the casters 410 are used to move the entire integrated air-water purification box 4 to avoid obstructing the treatment and operation space of medical staff. After the integrated air-water purification box 4 is moved to a suitable position, it is first secured by the brakes on the casters 410, and then the lifting seats 49 are lowered to fix the integrated air-water purification box 4. Since the integrated air-water purification box 4 is secured by four different lifting seats 49, it can be fixed even on uneven ground.

[0027] Example 2: This embodiment, based on the above embodiments, further defines the air purification system, such as... Figure 3 , Figure 4As shown, the air purification system 42 includes an air purification cylinder 421 and an air storage cylinder 422. The air inlet of the air purification cylinder 421 is connected to the air outlet pipe of the air compressor 44, which outputs compressed air. The air purification cylinder 421 is connected to the water treatment system 43 through a first air supply pipe, using the purified air to provide power to the water treatment system 43 to output purified water. The air purification cylinder 421 is connected to the air storage cylinder 422 through a second air supply pipe. The air storage cylinder 422 receives and stores the purified air. The air storage cylinder 422 outputs the stored purified air through a third air supply pipe. The third air supply pipe extends out of the housing 41 and connects to the dental handpiece 3 installed on the treatment table 2, providing power and air source for the operation of the dental handpiece 3.

[0028] The specific implementation process is as follows: after the air compressor 44 is started, the initial compressed air generated first enters the air purification cylinder 421. The air purification cylinder 421 removes impurities and microorganisms and outputs sterile compressed air that meets medical standards.

[0029] The purified compressed air is divided into two paths: The gas is directly supplied to the water treatment system 43 through the first gas supply pipe, which acts as a power source to squeeze the sterile water in the water treatment system, giving it stable pressure to meet the rinsing requirements of dental handpieces.

[0030] The air is delivered to the air storage tank 422 through the second air supply pipe. The air storage tank stores and stabilizes the pressure of the purified air. When the dental handpiece is not working, the air storage tank 422 stores air; when the handpiece is started, it directly outputs air at a stable pressure, avoiding pressure fluctuations caused by frequent start-stop of the compressor.

[0031] After the dental handpiece 3 is started, the air reservoir 422 delivers stable sterile air through the third air supply pipe to provide power for the handpiece turbine; at the same time, the water treatment system 43, driven by compressed air, delivers sterile water through the water supply pipe, working in synergy with the air.

[0032] The air inlet and outlet pipes inside the housing 41 operate continuously to maintain internal air circulation, prevent moisture from getting into components such as the purification cylinder and air storage cylinder, and avoid secondary pollution. Other parts of this embodiment are the same as those in the above embodiments and will not be repeated here.

[0033] Example 3: This embodiment further defines the structure of the air purifier cylinder 421 based on the above embodiments, such as... Figure 5As shown, the device includes an outer cylinder 4211 sealed at both ends. An air inlet plate 4213 is provided inside the outer cylinder 4211, which divides the interior of the outer cylinder 4211 into an upper first cavity 42111 and a lower second cavity 42112. An air filter device 4214 is installed in the first cavity 42111. Several air inlet holes 42131 are arranged on the outer edge of the air filter device 4214. The air inlet holes 42131 connect the first cavity 42111 and the second cavity 42112 inside the outer cylinder 4211. An air outlet pipe 4215 communicating with the interior of the air filter device 4214 is also provided at the top of the outer cylinder 4211. An air inlet pipe 4216 communicating with an air source is provided on the side wall of the second cavity 42112.

[0034] Compressed air enters the second cavity 42112 of the outer cylinder 4211 through the inlet pipe 4216. Because the second cavity 42112 is sealed, only the air inlets 42131 along the edge of the inlet plate 4213 at the top of the second cavity 42112 can evenly disperse into the first cavity 42111. When the compressed air contacts the inlet plate 4213, the water vapor in the compressed air will be pre-cooled and liquefied on the inlet plate 4213, accumulating in the second cavity 42112. The compressed air entering the first cavity 42111 passes through the air filter device 4214 and flows out through the outlet pipe 4215 above the inside of the air filter device 4214. Since the compressed air can only flow out through the air filter device 4214, all the compressed air will be purified before flowing out.

[0035] By setting the compressed air path in this way, the compressed air can pass through the air filter device 4214 evenly and relatively slowly, thereby obtaining a better air filtration effect and improving the filtration efficiency of the air filter device 4214. The filtered oil and water will flow under the action of gravity and enter the second cavity 42112 through the air inlet hole 42131 of the air inlet plate 4213 and converge.

[0036] The air filtration device 4214 includes an inner cylinder 42141, the top of which is sealed and fixedly connected to the inner side of the top of the outer cylinder 4211, and the bottom of which is sealed and fixedly connected to the middle of the air inlet plate 4213. An air filter screen 42142 is installed on the side wall of the inner cylinder 42141. An air outlet pipe 4215 at the top of the outer cylinder 1 connects to the interior of the inner cylinder 42141. An air inlet hole 42131 on the air inlet plate 4213 is located outside the outer cylinder 42141. The outer cylinder 4211 and the inner cylinder 42141 are coaxially arranged. The coaxial arrangement of the inner cylinder 42141 and the outer cylinder 4211, and the air filter screen 42142 installed on the side wall of the inner cylinder 42141, forms an annular filtration channel, increasing the filtration area. Compressed airflow passes from the outside of the inner cylinder 42141 to the inside through the air filter 42142. The filter area is large and uniform, which can fully adsorb particulate matter, aerosols and odors in the air. The coaxial structure facilitates processing and manufacturing, ensures symmetrical airflow path and reduces local resistance.

[0037] An ultraviolet (UV) sterilization lamp 4217 is sealed and installed in the middle of the sealing flange 4212. The lamp body of the UV sterilization lamp 4217 extends into the first cavity 42111 of the outer cylinder 4211 and is placed inside the inner cylinder 42141. When compressed air enters the inner cylinder 42141 through the air filter 42142, it undergoes secondary sterilization and disinfection by the UV sterilization lamp 4217 sealed in the middle of the sealing flange 4212, thoroughly killing pathogenic microorganisms carried in the air, eliminating bacteria and viruses in the air, reducing the risk of cross-infection, and further improving the safety of air use in dentistry. The upper part of the outer cylinder 4211 is sealed by the sealing flange 4212, and the bottom of the outer cylinder 4211 is sealed by the sealing plate 4218. The upper part of the inner cylinder 42141 of the air filter device 4214 is sealed and fixedly connected to the inside of the sealing flange 4212. This configuration ensures that air flows only through the inlet pipe 4216, air filter 4214, and outlet pipe 4215, preventing unfiltered air leakage and guaranteeing purification effectiveness. The sealed structure also prevents liquids, such as irrigation water during treatment, from seeping into the equipment, improving its durability. The sealing plate 4218 also has a sealable oil and water drain hole. Accumulated oil and water vapor can be periodically cleaned through the drain hole to prevent internal corrosion, maintain unobstructed airflow, extend equipment lifespan, and prevent obstruction during normal use without affecting the compressed air flow. Other parts of this embodiment are the same as those in the previous embodiment and will not be repeated.

[0038] Example 4: This embodiment, based on the above embodiment, further defines the water treatment system 43, such as... Figure 3 , Figure 6As shown, the water treatment system 43 includes a filtration mechanism 431 consisting of at least three filter elements connected in series, a dosing tank 432, a sterilization tank 433, and at least two water storage tanks 434. The inlet of the filtration mechanism 431 is connected to an external tap water source via an inlet pipe, and the outlet of the filtration mechanism 431 is connected to the bottom inlet of the sterilization tank 433 via a first water supply pipe. Filtered water enters the sterilization tank 433 from the bottom inlet through the first water supply pipe. The dosing tank 432 is connected to the sterilization tank 433 via a dosing pipe, and the dosing pipe is also equipped with a device to transfer the dosing tank 434 to the sterilization tank 433. The disinfectant solution in 32 is injected into the peristaltic pump in the sterilization tank 433; the water outlet at the top of the sterilization tank 433 is connected to a number of second water pipes matching the number of water storage tanks 434, and each second water pipe is connected to the top of an independent water storage tank 434. The water that has been sterilized in the sterilization tank 433 enters the corresponding water storage tank 434 through the water inlet at the top of the water storage tank 434 via the second water pipe; each water storage tank 434 is provided with an air inlet at the top connected to an air supply pipe, and the water outlet at the bottom is connected to the dental handpiece 3 via a third water supply pipe extending out of the box body 41, providing the dental handpiece 3 with sterilized water.

[0039] The specific implementation process is as follows: external tap water first enters the filtration mechanism 431 and is purified step by step through at least three filter elements connected in series: The first-stage filter element is 5μm PP cotton: it removes large particulate impurities such as silt, rust, and suspended solids from the raw water; The second-stage filter element, activated carbon, adsorbs residual chlorine, organic matter, and odors, reducing chemical pollution in the water. The third-stage filter element, a 0.1μm precision filter element or an RO reverse osmosis membrane, filters bacteria, colloids, and heavy metal ions to obtain preliminarily purified water.

[0040] The filtered clean water enters from the bottom of the sterilization tank 433, while the disinfectant solution in the dosing tank 432 is metered into the tank via a peristaltic pump. The disinfectant solution and purified water are thoroughly mixed in the tank by water flow agitation, killing residual microorganisms in the water, including bacteria, viruses, spores, etc. The sterile water after disinfection and sterilization is discharged from the outlet at the top of the disinfection and sterilization tank and distributed to at least two storage tanks 434 through the first water supply pipe. The water tank adopts a sealed design to avoid secondary pollution; when the water level in one water tank is lower than the threshold, it automatically switches to another water tank to ensure that the dental handpiece has a continuous and uninterrupted water supply.

[0041] The air inlet at the top of each water tank is connected to the sterile compressed air output from the air purification system. Compressed air creates a stable pressure inside the water storage tank, squeezing the sterile water inside the tank and discharging it from the lower outlet. Sterile water is delivered to the dental handpiece via a third water supply tube, working in conjunction with the air circuit to achieve rinsing and cooling functions during treatment, with the water supply pressure synchronized with the working rhythm of the dental handpiece. Other parts of this embodiment are the same as those in the previous embodiment and will not be repeated here.

[0042] Example 6: This embodiment, based on the above embodiment, further defines the disinfectant composition in the dosing tank 432 and the structure of the disinfection and sterilization tank 433, such as... Figure 7 As shown, the disinfectant solution in the dosing tank 432 is an aqueous solution of Jatropha curcas leaf extract. The disinfection and sterilization tank 433 includes a tank body 4331, with an inlet at the bottom and an outlet at the top. At least one layer of metal sterilization mesh 4332 is also provided inside the tank body 4331, placed between the inlet and outlet of the tank body 4331. The metal sterilization mesh 4332 is made of at least one of copper and zinc, or a copper-zinc alloy. A disinfection and sterilization lamp 4333 capable of irradiating ultraviolet light onto the tank body 4331 is provided on the top of the tank body 4331.

[0043] Jatropha curcas L., also known as tung oil tree, is a shrub or small tree belonging to the Euphorbiaceae family. It has smooth bark, alternate, ovate-orbicular or nearly orbicular leaves, and is monoecious. The inflorescence is a cyme. The capsule is nearly spherical and yellow when ripe. Jatropha curcas is widely distributed in southwestern and southeastern my country. It is a woody plant that thrives in poor soil and arid regions and is a natural medicinal plant.

[0044] Modern pharmacological studies have shown that Jatropha curcas root extract possesses anti-inflammatory and anti-tumor activities, but no medicinal components or drug formulations with application value have yet been developed from it. Phytochemical studies of Jatropha curcas have identified more than 40 diterpenoid compounds from its roots, including two novel diterpenoids, jatrophalactone and jatrophadiketone. Furthermore, curcusone compounds exhibit good cytotoxic activity (IC50: 1–4 μM), and their content is high (1‰–5‰). Large quantities of Jatropha curcas leaves and stems are discarded as byproducts and not utilized.

[0045] This invention uses pure methanol and a 50% methanol-water solution to extract *Jatropha curcas* leaves using alcohol and water extraction, respectively. The extracts are then analyzed by liquid chromatography-mass spectrometry (LC-MS) and identified using Compound Discovery. Figures 8-11 As shown, 15 compounds were identified (see chromatogram). Figure 1 , 2(Table 1) are alkaloid compounds such as betaine; sugar alcohols such as allicin; flavonoids such as shambutol, isoshambutol, vitexin rhamnoside, vitexin, isovitexin, epifiscinidol-4alpha-ol, sennain, isosennain, and cosmosin; organic acid compounds such as citric acid; and xanthine compounds such as 1,9-dimethyluric acid.

[0046] Jatropha curcas leaf extract was dissolved in water to prepare an aqueous solution with a mass fraction of 1%–10%. This aqueous solution was weakly alkaline with a pH value of 7.5–7.8. Based on the identified compounds, it is known that the extract itself has a certain bactericidal effect.

[0047] The sterilization tank 433 is equipped with a metal sterilization mesh 4332. The metal sterilization mesh 4332 is made of at least one of copper and zinc, or a copper-zinc alloy, and it also has a sterilization effect.

[0048] Using an aqueous solution of Jatropha curcas leaf extract as the disinfectant in the dosing tank 432, combined with the metal sterilization mesh 4332 in the sterilization tank 433, the two can achieve a synergistic sterilization effect. Specific verification experiments are as follows: I. Experimental Objective This study compared the bactericidal effects of three methods—using Jatropha curcas leaf extract alone, using metal mesh alone, and using Jatropha curcas leaf extract in combination with metal mesh—on common oral pathogens, and verified the superiority of synergistic effects.

[0049] II. Experimental Materials and Reagents Test strains: Typical pathogenic bacteria used in oral treatment were selected (all were standard strains): Staphylococcus aureus (ATCC 6538) Escherichia coli (ATCC25922) Candida albicans (ATCC10231) Jatropha curcas leaf extract: Take 1g of Jatropha curcas leaf sample that has passed through a 50-mesh sieve into an Erlenmeyer flask, add 5mL of methanol and 50% methanol respectively, and sonicate at 40kHz for 45min to obtain the ethanol extract of Jatropha curcas leaf.

[0050] Take 1g of Jatropha curcas leaf sample that has passed through a 50-mesh sieve and place it in a round-bottom flask. Add 30ml of water and soak for 15min. Then reflux in a 90℃ water bath for 2h. Filter, take the filter residue, add another 30ml of water, reflux for 2h under the same conditions, filter, combine the filtrates, and rotary evaporate to 10ml to obtain the Jatropha curcas leaf water extract.

[0051] Combine the water and alcohol extracts of Jatropha curcas leaves to prepare an aqueous solution with a concentration of 100 mg / mL (preliminary tests verified that this concentration is an effective disinfection concentration with no cytotoxicity), and store at 4°C for later use.

[0052] Metal mesh: Select pure copper mesh with broad-spectrum bactericidal properties (copper ions can destroy microbial cell membranes), with a specification of 100 mesh (pore size 0.154mm, to ensure full contact with bacterial solution during filtration), cut into circles with a diameter of 5cm, and sterilize by high-pressure steam (121℃, 20min) before use.

[0053] Other reagents and equipment: Nutrient agar medium (for bacteria), Sandburg agar medium (for fungi), sterile physiological saline, phosphate buffered saline (PBS, pH 7.2). Clean bench, biochemical incubator (37℃), autoclave, colony counter, pipettes (1mL, 100μL), sterile petri dishes, sterile test tubes, etc.

[0054] III. Experimental Design 1. Experimental grouping (each group was repeated 3 times to avoid random error) Blank control group (CK): Contains only bacterial solution, without any sterilization treatment; Single extract group (Group A): bacterial suspension and Jatropha curcas leaf extract (final concentration 100 mg / mL); Individual metal mesh group (Group B): The bacterial solution is filtered through a metal mesh; Combined use group (Group C): The bacterial solution was first filtered through a metal mesh, and then jatropha leaf extract (final concentration 100 mg / mL) was added.

[0055] 2. Key variable control Bacterial concentration: Each strain was cultured to the logarithmic growth phase and diluted with sterile physiological saline to 1×10⁻⁶. 6 CFU / mL (calibrated by plate count method); Treatment time: Each group was treated at 25℃ (room temperature) for 10 min, 20 min, and 30 min (covering the routine time for a single disinfection during oral treatment). Operating environment: The entire process is carried out in a clean bench to ensure aseptic operation and avoid external contamination.

[0056] IV. Test Procedure Preparation of bacterial culture: Take the slant culture of each strain, inoculate it into liquid culture medium, and incubate at 37℃ with shaking for 18-24 h (bacteria) or 48 h (fungi). Dilute with sterile physiological saline to 1×10⁻⁶. 6 CFU / mL, for later use.

[0057] Processing for each group: Blank control group (CK): Take 1 mL of bacterial culture, add 9 mL of sterile physiological saline (diluted 10 times), and let stand at 25℃ for the corresponding time (10 / 20 / 30 min).

[0058] Extract-only group (Group A): Take 1 mL of bacterial culture, add 1 mL of Jatropha curcas leaf extract (final concentration 100 mg / mL), mix well, and let stand at 25°C for the corresponding time. After the time is up, add 8 mL of sterile physiological saline (diluted 10 times) to terminate the reaction.

[0059] Group B (Separate metal mesh): Pass 1 mL of bacterial solution through a sterile metal mesh (with sterile funnel for assisted filtration), collect the filtrate into a sterile test tube, let it stand at 25°C for the corresponding time, and add 9 mL of sterile physiological saline (diluted 10 times).

[0060] Group C (using the combination of the two): 1 mL of bacterial culture was first filtered through a metal mesh, and after collecting the filtrate, 1 mL of Jatropha curcas leaf extract (final concentration 100 mg / mL) was added. The mixture was allowed to stand at 25°C for the corresponding time, and then 8 mL of sterile physiological saline (diluted 10 times) was added to terminate the reaction.

[0061] Colony counting: After each treatment, 100 μL of the diluted solution was spread on the corresponding culture medium plate (nutrient agar for bacteria, Saburg weak agar for fungi), and incubated at 37°C for 24 h (bacteria) or 48 h (fungi). The number of colonies (CFU) on the plate was counted using a colony counter, and the number of viable bacteria per milliliter of bacterial solution was calculated.

[0062] V. Calculation of Results Viable bacteria count: Viable bacteria count per milliliter of bacterial solution = number of colonies on plate × dilution factor × 10 (since 100 μL = 0.1 mL for plating).

[0063] Sterilization rate: Sterilization rate (%) = (Number of viable bacteria in the blank control group - Number of viable bacteria in the treatment group) / Number of viable bacteria in the blank control group × 100% VI. Expected Results and Analysis 1. Data records are shown in Table 1 (taking a processing time of 10 minutes as an example). Table 1: Experimental Data Recording Table for Each Group

[0064] 2. Synergistic Effect Analysis Statistical analysis (analysis of variance) showed that the sterilization rate of group C (used in combination) was significantly higher than that of groups A and B (P<0.05), and the sterilization rate of group C increased more significantly with the extension of treatment time (reaching more than 95% at 30 min).

[0065] Synergistic mechanism: The physical interception of the metal mesh can reduce the number of live bacteria in the bacterial solution. At the same time, copper ions damage the cell membrane of microorganisms, increasing their permeability to the jatropha leaf extract. The jatropha leaf extract (containing flavonoids, terpenes and other components) can inhibit the activity of microbial enzymes and damage DNA structure, complementing the "membrane damage" effect of metal ions and significantly improving the sterilization efficiency.

[0066] This shows that when jatropha leaf extract is used in combination with metal mesh, the bactericidal rate against common oral pathogens is significantly higher than when either is used alone, proving that the combination of the two can enhance the disinfection effect and is more suitable for the aseptic requirements of oral treatment equipment.

[0067] Because it uses plant extracts as the disinfectant, it contains few harmful components. Combined with a metal sterilization mesh, it ensures disinfection effectiveness while avoiding the residual toxicity of using pure chemical disinfectants for oral disinfection, thus guaranteeing the safety of water used for patients' oral treatment.

[0068] To further improve the disinfection effect of oral water, a disinfection and sterilization lamp 4333 capable of irradiating ultraviolet light onto the top of the tank 4331 of the disinfection and sterilization tank 433 is installed. This enhances the disinfection and sterilization effect of the oral water.

[0069] The oral water that ultimately flows from the mobile phone was sent to the Product Quality Inspection and Research Institute for testing. The test results are shown in Table 2. Table 2 Water Sample Test Results

[0070] According to the test results, the tap water treated by the water treatment system of this invention has reached a sterile state, which can guarantee the absolute safety of oral water.

[0071] Example 7: This embodiment further defines the structure of the integrated air-water purification box 4 based on the above embodiments, such as... Figure 2 As shown, an electrical mounting plate 47 is provided on the top of the housing 41, and an integrated control circuit is installed on the electrical mounting plate 47. Each pipe inside the housing 41 is equipped with an electromagnetic control valve, a flow meter, and a pressure gauge. The flow meter, pressure gauge, and electromagnetic control valve are all electrically connected to the integrated control circuit. A control panel 48 is also provided at the front end of the housing 41. The control panel 48 monitors the air and water flow and air pressure in the pipes through the flow meter and pressure gauge via the integrated control circuit, and feeds the feedback to the control panel, thereby realizing the control of the electromagnetic control valves on all pipes.

[0072] The treatment table 2 is also equipped with a heater, which can heat the water introduced into the dental handpiece 3.

[0073] Specific control piping, such as Figure 12 As shown, due to the excessive number of flow meters, pressure gauges, and solenoid control valves, therefore Figure 12 The standard indicates that some pipes are equipped with flow meters, pressure gauges, and solenoid control valves. In reality, each air inlet pipe, air outlet pipe, and water outlet pipe is controlled by a corresponding flow meter, pressure gauge, and solenoid control valve, and the flow rate and pressure are monitored. Temperature sensors are installed on the pipes connected to the heating pipes, which can feed back the temperature inside the pipes to the treatment table 2, and display it on the monitor on the treatment table 2.

[0074] The temperature of the water coming out of the dental handpiece 3 can be controlled by adjusting the flow rates of the cold and hot water pipes.

[0075] Example 8: This embodiment, based on the above embodiment, further defines the structure of the air inlet duct 45, such as... Figure 3 As shown, the air inlet pipe 45 installed on the upper part of the housing 41 is a vertical bend. One end of the air inlet pipe 45 is installed on the upper inner side of the housing 41 and connects to the outside. The other end of the air inlet pipe 45 is vertically downward open and connects to the inside of the housing 41. An exhaust fan is also installed in the middle of the air inlet pipe 45 to draw outside air into the housing 41. A screen is also installed at the inlet of the air inlet pipe 45. The air inlet pipe 45 is designed as an "L-shaped" or "right-angle bend" structure to form a physical barrier. Outside air must first enter through the horizontal section and then turn vertically downward to enter the housing. This can effectively prevent dust and water droplets (such as condensation on the ceiling and splashing water) from the external environment from falling directly into the housing. The vertical downward opening direction can guide the airflow to flow to the lower part of the housing, avoiding direct impact of the incoming air on the precision components of the upper part of the housing (such as the electrical components of the air purification cylinder and the sterilization tank), and reducing component vibration or dust adhesion caused by airflow disturbance.

[0076] The screen at the air inlet is the first filtration barrier, which can intercept large particulate impurities in the outside air (such as lint, insects, and coarse dust) to prevent them from entering the housing and contaminating the internal system (such as adhering to the filter surface to reduce purification efficiency, or entering the air storage tank to affect the cleanliness of the air source). The central exhaust fan provides active ventilation power, forcibly drawing outside air into the enclosure to ensure stable airflow inside (avoiding insufficient airflow from natural ventilation). At the same time, continuous air intake creates a slight positive pressure inside the enclosure (relative to the external environment), preventing unpurified outside air from flowing back into the enclosure through gaps.

[0077] After the airflow enters from the top of the chamber, it flows through the air purification system 42, water treatment system, air compressor and other core components, which can remove the heat generated by the operation of the components (such as the heat dissipation of the compressor operation and the heat of the ultraviolet lamp), thus preventing the temperature inside the chamber from becoming too high. Simultaneously, the airflow can promptly remove moisture from the air inside the chamber (such as moisture separated during air purification and possible trace leaks from the water treatment system), reducing the humidity inside the chamber (controlled at RH≤60%), preventing microbial growth and corrosion of metal components, and ensuring long-term sterile operation of the system. Other parts of this embodiment are the same as those in the above embodiments and will not be repeated.

[0078] Example 9: This embodiment, based on the above embodiment, further adds a muffler 46, such as... Figure 3 As shown, a silencer 46 is also installed at the air outlet on the upper part of the housing 41. The silencer 46 can eliminate the high-frequency noise generated when the airflow forms turbulence and eddies in the air outlet pipe during airflow inside the housing 41, and when it impacts the outside air upon discharge, causing air vibration. At the same time, it can reduce the vibration noise generated by the air compressor 44 inside the housing 41. In this way, the entire air-water integrated purification box 4 can maintain a relatively quiet state during operation, avoiding noise interference for medical staff during patient surgery. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0079] Example 10: This embodiment, based on the above embodiment, further adds a pipeline check valve 31, such as... Figures 13-15 As shown, at least one pipe check valve 31 is nested at one end of the dental handpiece 3 that connects to the water pipe and air pipe. The pipe check valve 31 includes a body 311 with external threads, a copper sleeve 316 with internal threads nested on the body 311, a locking nut 317 threaded onto the copper sleeve 316, an internal thread matching the external thread of the locking nut 317, and an inwardly protruding retaining ring 318 in the center of the locking nut 317. A limiting ring 319 protruding outward is provided at the end of the body 311 where it connects to the dental handpiece 3. The locking nut 317 is threadedly connected to the copper sleeve 316, and the retaining ring 318 inside it abuts against the limiting ring 319 at the end of the body 311.

[0080] The dental handpiece 3 has an external thread at its end that matches the internal thread of the locking nut 317. The locking nut 317 is threadedly connected to the end of the dental handpiece 3, thereby detachably connecting the body 311 of the pipe check device 31 to the dental handpiece 3.

[0081] The main body 311 is connected to the third water pipe and the third air pipe at the other end of the dental handpiece 3. The main body 311 is equipped with parallel and non-connected hot water pipe 3, cold water pipe 313, air inlet pipe 314, and return pipe 315. The treatment table 2 is equipped with a heater. The third water pipe is split when passing through the treatment table 2. One of them is a pipe connected to the hot water pipe 312 in the main body 311, and the other is a pipe connected to the cold water pipe 313 in the main body 311. When the water in the pipe connected to the hot water pipe 312 flows through the treatment table 314, the treatment table has a built-in heater that can heat the water in the pipe. A temperature sensor is installed on the pipe to transmit the water temperature in the pipe to the treatment table 2 and display it.

[0082] The air inlet pipe 314 inside the main body 311 is connected to the third air supply pipe to deliver clean high-pressure gas to the dental handpiece 3. The return pipe 314 inside the main body 311 sends out the incoming high-pressure gas and water flow.

[0083] To ensure a good seal, sealing gaskets 310 are provided at both ends of the main body 311.

[0084] Each of the hot water pipe 3, cold water pipe 313, and air inlet pipe 314 is provided with a check cavity. A check mechanism is installed within each check cavity. The check mechanism includes a sealing block 3111 and a spring 3112 that abut against each other. The sealing block 3111 and spring 3112 abut against both ends of the check cavity, with the sealing block 3111 facing the side where the gas or liquid flows. Other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0085] Example 11: Based on the above embodiments, this embodiment further adds a life monitoring system. The treatment table 2 is also equipped with a life monitoring system. The life monitoring system can monitor the patient's vital signs parameters in real time and provide feedback to the doctor. When the patient's vital signs are unstable, it will issue an early warning and cut off the air and water supply to the dental handpiece 3, stopping the operation of the dental handpiece 3.

[0086] The life monitoring system includes a wristband for the patient to wear, a data analysis terminal, and a display. The wristband is equipped with a sensor module, a signal processing module, a data transmission module, and a power management module. The sensor module includes an electrocardiogram (ECG) sensor, a blood oxygen sensor, and a motion sensor. The ECG sensor is used to collect the patient's ECG signals to obtain heart rate and heart rhythm data. The blood oxygen sensor is used to obtain the patient's blood oxygen saturation and pulse rate data through photoelectric detection. The motion sensor is used to detect the patient's limb activity status. The signal processing module is electrically connected to the sensor module and is used to amplify, filter, and perform analog-to-digital conversion on the raw signal collected by the sensor module to obtain a standardized digital signal. The data transmission module is electrically connected to the signal processing module and transmits the processed digital signal to the data analysis terminal via wireless communication. The power management module is electrically connected to the sensor module, signal processing module and data transmission module respectively, and includes a rechargeable lithium battery, a charging interface and a low power control unit, which is used to power each module and realize power monitoring and energy consumption management. The data analysis terminal includes a wireless receiving module, a data processing module, a storage module, an early warning algorithm module, and a communication interface module. The wireless receiving module is matched with the data transmission module of the wristband to receive vital sign data transmitted by the wristband; The data processing module has a built-in high-performance processor that filters and analyzes the received data, and generates a diagnostic report for the patient's body based on the received data through the AI ​​program in the high-performance processor. The storage module stores the patient's historical vital signs data and analysis results; The early warning algorithm module has a built-in preset vital sign abnormality judgment algorithm, which triggers an early warning when the data exceeds the safe range. The communication interface module is used for data interaction with the display; The display includes a display module, a control module, an interaction module, and a power module; The display module is a high-definition LCD screen, which is used to intuitively present real-time data such as the patient's heart rate, blood oxygen saturation, and exercise status, as well as abnormal warning information; The control module receives signals transmitted from the data analysis terminal and controls the switching, updating, and triggering of warning prompts for the displayed content. The interactive module is a touch screen, which supports medical staff to manually set monitoring parameters, view historical data and other interactive operations. The power module provides power to the display and can be powered by an external power source or share a power source with the treatment equipment. Other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0087] Example 12: This embodiment, based on the above embodiments, further defines the specific structure of the dental chair 1. The dental chair 1 is equipped with multiple independently adjustable airbags, which are distributed in the backrest, seat cushion, and headrest areas of the chair, and are used to change the support shape of the chair by adjusting the inflation amount of the airbags. Other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
