Description

Technical Field

[0001] The invention relates to the field of medical disinfection, and in particular to a water channel composite disinfection system and a disinfection method for a comprehensive oral treatment table. Background Art

[0002] The comprehensive oral treatment table is an important equipment for the diagnosis and treatment of dental diseases. Its water system is composed of narrow and slender pipes, which are prone to breed bacteria and form biofilms. The biofilm has a special structure and is difficult to remove by conventional means. It will enter the patient's mouth with water or be transmitted through aerosols, threatening the health of doctors and patients. Although my country has proposed waterway microbial standards, the actual pass rate is low. Surveys in many places have shown that bacterial contamination in pipeline water of various oral treatment institutions is still very serious.

[0003] In the prior art, the solutions include physical and chemical methods. Physical methods such as centralized pure water supply, filtration or anti-back-absorption equipment can only prevent foreign bacteria, but cannot solve the problem of old biofilm, and are prone to clogging and failure, with high maintenance costs. Chemical methods such as manual preparation of chlorine-containing disinfectants, installation of hypochlorous acid or ozone water disinfectors, etc., are cumbersome and have safety hazards. Chlorine-containing disinfectants will corrode pipelines if used for a long time. Installing disinfection equipment also has problems such as corrosion, odor, and unstable effect. There is a lack of equipment that can simultaneously solve the problem of old biofilm in pipelines and maintain daily sterile conditions. For this reason, the present invention provides a waterway composite disinfection system and disinfection method for a comprehensive oral treatment table. Summary of the invention

[0004] In order to make up for the shortcomings of existing technologies, physical methods can only prevent foreign bacteria, but cannot solve the problem of old biofilms, and are prone to clogging and failure, with high maintenance costs; chemical methods are cumbersome to manually configure and operate, and there are safety hazards, and chlorine-containing disinfectants will corrode pipelines if used for a long time; installing disinfection equipment also has problems such as corrosion, odor, and unstable effects; there is a lack of equipment that can simultaneously solve the problem of old biofilms in pipelines and maintain daily sterility.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a water channel composite disinfection system and disinfection method for a comprehensive oral treatment table described in the present invention comprises: Coarse filter, used for preliminary filtration of incoming municipal water supply to remove large particles of impurities in the water; A function switching button, which is arranged on the outside of the device and is used to switch the disinfection mode. The button has at least two states; The PCB central control board is used to control the operation of the entire disinfection system. It is electrically connected to the function switch button and coordinates the work of various components according to the button status; The disinfection mode unit is activated when the function switch button is in the first state, comprising: A strong acid disinfectant module, which includes a strong acid cleaning liquid storage tank, a one-way valve, a water outlet diaphragm pump and a pressure transmitter; the pressure transmitter is used to detect the water channel opening signal of the oral comprehensive treatment table and transmit it to the PCB central control board to control the water outlet diaphragm pump to pass the strong acid cleaning liquid into the oral comprehensive treatment table for pipeline cleaning, and a water stop valve is provided to prevent sewage from backflowing and contaminating the storage tank; The ozone water generator disinfection module includes a water flow switch, an ozone water generator, a check valve, a water outlet diaphragm pump and a pressure transmitter; when the water flow switch detects that water is flowing through, the central control PCB board supplies power to the ozone water generator to make it work and produce high-concentration ozone water of ≥30mg / L, and the check valve ensures that there is water in the ozone water generator; The hypochlorous acid generator disinfection module comprises a water flow switch, a hypochlorous acid generator, an electrolyte tank and a check valve; when the water flow switch detects that water is passing through, the central control panel allows the electrolyte in the electrolyte tank to enter the hypochlorous acid generator at a set flow rate to mix with municipal tap water and energize electrolysis to produce hypochlorous acid disinfectant, which enters the oral comprehensive treatment table through the check valve; The continuous antibacterial mode unit is activated when the function switch button is in the second state. It includes a solenoid valve, a circulating water tank, a high-pressure diaphragm pump, a plasma activated water generation module, a submersible pump, a water storage tank, a pressure transmitter and a water outlet diaphragm pump. It is used to generate plasma activated water to inhibit bacteria in the pipeline and for use in the comprehensive oral treatment table.

[0006] Preferably, the function switching button is a push button, which starts the disinfection mode unit when pressed, and starts the continuous antibacterial mode unit when not pressed.

[0007] Preferably, the water flow switch is a capacitive flow switch, an ultrasonic flow switch or an impeller flow switch, which is used to detect water flow conditions to control the operation of related disinfection modules.

[0008] Preferably, the check valve is a swing check valve or a spring check valve, which is used to ensure the presence of water in a specific disinfection module and reduce the risk of damage to the equipment due to water backflow.

[0009] Preferably, in the continuous antibacterial mode unit, when the water storage tank feeds back a signal to the central control PCB that it is not full, the solenoid valve is opened to allow municipal water to enter; when the circulating water tank feeds a signal to the PCB central control board that the water tank is full, the solenoid valve is closed to stop water intake, and at the same time, the high-pressure diaphragm pump and the high-voltage power supply start working; when the set time is reached, the high-pressure diaphragm pump and the high-voltage power supply are turned off, and the submersible pump starts working; when the circulating water tank gives a signal that the water tank is empty or the water storage tank gives a signal that the water tank is full, the submersible pump is turned off; when the pressure transmitter detects that the pipeline pressure reaches the set pressure, it gives a signal to the PCB central control board to release water, and the water outlet diaphragm pump is turned on to pump water out of the water storage tank for use on the comprehensive oral treatment table.

[0010] Preferably, in the disinfection mode unit, each disinfection module can work individually or in combination according to actual needs to cope with different degrees of biofilm contamination, and during the working process, the disinfection effect can be monitored in real time, such as by detecting the bacterial content or biofilm residue in the water after disinfection, and adjusting the disinfection parameters to improve the removal effect of old biofilm.

[0011] Preferably, the plasma activated water generated by the continuous antibacterial mode unit can maintain relatively stable antibacterial performance during the use of the oral comprehensive treatment table, and is not affected by external environmental factors (such as temperature, light, etc.) to a certain extent. The antibacterial effect on the pipeline is sustainable to a certain extent, and can inhibit the bacteria from growing again to form biofilm to a certain extent. At the same time, the plasma activated water has less corrosive effect on various components of the oral comprehensive treatment table (such as metal components, plastic components, etc.), reducing the risk of equipment damage due to water backflow.

[0012] Preferably, the system can automatically record operating data during operation, including disinfection mode switching time, working hours of each component, water quality monitoring data, etc., to facilitate subsequent query and analysis for equipment maintenance, performance optimization and troubleshooting, and can transmit data to a remote monitoring platform through a wireless communication module to achieve remote monitoring and management.

The plasma activated water generated by the continuous antibacterial mode unit purifies municipal tap water while inhibiting bacteria inside the pipeline, and has a certain antibacterial effect on oral pathogens such as Candida albicans in the patient's mouth. During the water supply process, according to the water demand of different oral treatment operations (such as teeth cleaning, filling, tooth extraction, etc.), the supply volume and supply pressure of plasma activated water are reasonably controlled to ensure the smooth progress of the treatment process; S4: Continuously monitor the water quality and equipment operating status at the same time.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] The municipal water supply is introduced into the disinfection machine, and after passing through the coarse-effect filter, it enters different disinfection modules according to needs, and the water with disinfection effect is produced and enters the oral comprehensive treatment table through the water valve to disinfect the pipeline.

[0030] There is a function switch button on the outside of the device. When the "mode switch button" is pressed, it is in ozone disinfection mode, which can generate ozone water with high concentration of ozone water; when it is not pressed, it is in continuous antibacterial mode, which can generate non-toxic, harmless, plasma-activated water with antibacterial properties. Both modes of the device are controlled by the PCB central control board.

[0031] The main disinfection module of the disinfection mode can be Figure 1 The strong acid disinfectant module shown, Figure 2 The ozone water generator disinfection module shown can also be Figure 3 The hypochlorous acid generator disinfection module shown in the figure; when the main disinfection module is a strong acid cleaning fluid, such as Figure 1 The disinfection part shown includes a strong acid cleaning liquid storage tank, a one-way valve, a water outlet diaphragm pump and a pressure transmitter. When the pressure transmitter detects that the water circuit of the oral comprehensive treatment table is open, it transmits a signal to the PCB central control board to open the water outlet diaphragm pump to pass the strong acid cleaning liquid into the oral comprehensive treatment table for pipeline cleaning. The water stop valve prevents the sewage after cleaning from flowing back and contaminating the storage tank; when the main disinfection module is an ozone water generator, such as Figure 2The disinfection part shown includes a water flow switch, an ozone water generator, a check valve, a water outlet diaphragm pump, and a pressure transmitter; the water flow switch includes a capacitive flow switch, an ultrasonic flow switch, an impeller flow switch, etc.; its main function is to detect whether water is flowing; when water flows, the central control PCB board supplies power to the ozone water generator to make it work; when no water flows, the power supply is stopped to prevent the ozone water generator from being dry-burned and damaged; the ozone water generator is the core component for the production of ozone water, which can be a catalytic electrolysis ozone water generator or a PEM membrane electrolysis ozone water generator; it produces high-concentration ozone water of ≥30 mg / L to remove stubborn and old biofilms; the specific structure and working principle of the ozone water generator belong to the prior art in this technical field, and the present invention has not improved it, so it will not be repeated; the check valve can be a swing type, a spring type, etc., and its main function is to ensure that there is water in the ozone water generator and extend the service life of the equipment; when the main disinfection module is a hypochlorous acid generator, such as Figure 3 The disinfection part shown includes a water flow switch, a hypochlorous acid generator, an electrolyte tank, and a check valve; when the water flow switch detects that water is fed back to the PCB central control board, the central control board allows the electrolyte in the electrolyte tank to enter the hypochlorous acid generator at a set flow rate and mix with municipal tap water, and after power is turned on and electrolyzed, hypochlorous acid disinfectant is generated, which enters the oral comprehensive treatment table through the check valve; the specific structure and working principle of the hypochlorous acid generator belong to the prior art in this technical field, and the present invention does not improve it, so it will not be repeated.

[0032] The continuous antibacterial mode includes a solenoid valve, a circulating water tank, a high-pressure diaphragm pump, a plasma activated water generating module, a submersible pump, a water storage tank, a pressure transmitter, and a water outlet diaphragm pump; when the water storage tank feeds back a signal that it is not full to the central control PCB, the solenoid valve is opened to allow municipal water to be supplied; when the circulating water tank sends a signal that the water tank is full to the PCB central control board, the solenoid valve is closed to stop the water supply, and at the same time, the high-pressure diaphragm pump and the high-voltage power supply start working; when the set time is reached, the high-pressure diaphragm pump and the high-voltage power supply are turned off, the submersible pump starts working, and when the circulating water tank sends a signal that the water tank is empty or the water storage tank sends a signal that the water tank is full, the submersible pump is turned off; when the pressure transmitter detects that the pipeline pressure reaches the set pressure, it sends a water discharge signal to the PCB central control board, and opens the water outlet diaphragm pump to pump water out of the water storage tank for use on the oral comprehensive treatment table.

[0033] All processes of this device are controlled by the PCB central control board. The user only needs to operate the mode switching button on the side of the device; the specific signal output module and signal input module are controlled by Figure 4 shown.

[0034] The present invention also relates to a method for using the system, which specifically includes the following steps: when the device is installed for the first time and connected to a comprehensive oral treatment table, the device is first switched to a disinfection mode, the water inlet and all treatment table outlets are opened, and the device enters the operating state 2 minutes later and starts timing for 30 minutes when the highest concentration is reached, and the pipeline is repeatedly flushed.

[0035] Then switch the equipment to continuous antibacterial mode, open all water outlets of the treatment table and flush the pipelines until the outlet water is plasma-activated water.

[0036] Finally, the continuous antibacterial mode is used continuously for water supply in daily diagnosis and treatment.

[0037] The use of the above water supply method is different from the traditional oral comprehensive treatment unit water disinfection method, which requires regular use of high-concentration disinfectant water to disinfect the pipes and cannot guarantee that the pipes are in a sterile state during a disinfection cycle. It is also different from other disinfection equipment that requires daily pipe flushing and requires manual operation. As long as the equipment is in normal use, it can achieve fully automatic, all-weather antibacterial treatment of the pipes, and can continuously ensure that the total number of colonies in the water outlet of the pipes meets the oral comprehensive treatment unit water microbial standards to a certain extent.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
