Description

Technical Field

[0001] The present invention relates to the technical field of air purification and germ sterilization, and in particular to an intelligent system for air purification and germ sterilization in a ward. Background Art

[0002] As a key place for patients to receive treatment and rehabilitation, the quality of the air in the ward has a vital impact on the patient's recovery and the health of medical staff. In the specific environment of the ward, multiple factors are intertwined, resulting in severe challenges to air quality.

[0003] First, patients themselves are often carriers of germs. Due to illness, patients’ body resistance is reduced, becoming a potential source of germ breeding and spread. For example, patients with respiratory diseases release a large number of germs into the air during daily activities such as breathing, coughing, and sneezing, such as influenza virus and pneumococcus. These germs are suspended in the air and can easily be inhaled by other patients or medical staff, causing cross infection.

[0004] Secondly, there is a frequent flow of people in the ward. Medical staff need to frequently go in and out of the ward to diagnose, treat and care for patients, and the patients' families also come to visit. The large number of people coming in and out not only brings in pathogens from the external environment, but also increases air disturbance, causing the originally settled pathogens to be suspended in the air again, further increasing the risk of pathogen transmission.

[0005] Furthermore, the ward space is relatively closed. In order to ensure the stability and privacy of the patient treatment environment, the ward is usually kept relatively closed. Although this is conducive to the control of environmental parameters such as temperature and humidity, it also leads to poor air circulation. Fresh air is difficult to enter fully, and dirty air cannot be discharged in time, causing pollutants such as germs, odors, dust, and volatile organic compounds (VOCs) in the air to gradually accumulate, and the air quality continues to deteriorate.

[0006] At present, there are many drawbacks in the methods and equipment used for air purification and germ elimination in wards. The working principle of traditional air purifiers is mainly based on simple filter filtration. Although they can intercept some larger particles of dust and hair, they have very limited removal effects on tiny germs and gaseous harmful pollutants, such as formaldehyde, benzene and other volatile organic compounds. The particle size of germs is usually at the micron or even nanometer level, which can easily penetrate ordinary filters and continue to spread in the air.

[0007] Spraying chemicals is a common method of disinfecting germs. By spraying chemical disinfectants into the air or on the surface of objects, germs can be killed to a certain extent. However, the use of chemical agents has many hidden dangers. On the one hand, the residue of the agent will cause potential harm to human health, especially for patients with low immunity, which may cause allergic reactions, respiratory irritation and other problems. On the other hand, long-term and frequent use of chemical agents will cause bacteria to develop drug resistance, reduce the effectiveness of disinfection, and make future prevention and control work more difficult.

[0008] Ultraviolet disinfection lamps are also one of the commonly used disinfection equipment. They achieve the purpose of sterilization by emitting ultraviolet rays to destroy the DNA structure of bacteria. However, ultraviolet disinfection lamps need to be used in an unmanned environment, which greatly limits their use time and scenarios. Wards are places where patients stay for 24 hours. It is impossible to keep ultraviolet disinfection lamps on when patients are present, thus failing to meet the ward's all-weather air purification and germ disinfection needs.

[0009] In addition, most existing purification and disinfection equipment lacks intelligent control capabilities. They often operate in a fixed mode and cannot automatically adjust the working mode in real time according to the actual air quality and germ concentration in the ward. For example, when the germ concentration is low, the equipment still operates at a high intensity, resulting in energy waste and equipment loss; and when the air quality deteriorates sharply, the equipment cannot increase the purification and disinfection efforts in time, resulting in poor purification and disinfection effects.

[0010] To sum up, it is urgent to develop an air purification and germ disinfection system that can adapt to the complex environment of the ward and integrates efficient purification, precise disinfection, and intelligent control to meet the strict requirements of modern medical environments for air quality and protect the health of patients and medical staff. Summary of the invention

[0011] In order to solve the above problems, especially to address the deficiencies in the prior art, the present invention provides an intelligent system for ward air purification and germ disinfection that can solve the above problems.

[0022] A further solution of the present invention is that the series of high-precision sensors include a pathogen concentration sensor, a particulate matter sensor, and a volatile organic compound sensor. The pathogen concentration sensor uses fluorescent quantitative PCR technology or immunofluorescence technology to detect the concentration of pathogens in the air, the particulate matter sensor measures the particulate matter content through the laser scattering principle, and the volatile organic compound sensor uses a semiconductor gas sensitive element to detect the VOC concentration.

[0023] A further solution of the present invention is that the filter unit includes a primary filter screen, the primary filter screen is connected to a high-efficiency air filter, and the high-efficiency air filter is connected to an activated carbon filter screen.

[0024] A further solution of the present invention is that the pathogen disinfecting unit includes an ultraviolet disinfection device, a plasma disinfection device, and a photocatalytic disinfection device, and the ultraviolet disinfection device is connected to the photocatalytic disinfection device through the plasma disinfection device.

[0025] A further solution of the present invention is that the ultraviolet disinfection device includes a first ventilation duct, a plurality of groups of evenly distributed deep ultraviolet LED lamps are connected to the first ventilation duct, the plasma disinfection device includes a second ventilation duct connected to the first ventilation duct, a plasma discharger is connected to the second ventilation duct, and the photocatalytic disinfection device includes a third ventilation duct connected to the second ventilation duct, a photocatalyst box and an ultraviolet irradiation lamp corresponding to the photocatalyst box are connected to the third ventilation duct.

[0026] A further solution of the present invention is that the air circulation unit includes a fourth ventilation duct connected to the third ventilation duct, and the fourth ventilation duct is connected to a high-performance fan.

[0027] A further solution of the present invention is that the alarm module is an audible and visual alarm.

[0028] A further solution of the present invention is that the central control module is based on a high-performance microprocessor and is equipped with an intelligent algorithm developed based on big data analysis and machine learning algorithms, and the central control module is connected to a hospital information system.

[0029] A further solution of the present invention is that the data storage and analysis module includes a large-capacity storage device, and the large-capacity storage device is connected to the intelligent analysis module.

[0030] A further solution of the present invention is that the large-capacity storage device is a high-performance hard disk array or a cloud storage service, and the intelligent analysis module is an analysis module that uses advanced data analysis algorithms, and the data analysis algorithms include but are not limited to data mining, statistical analysis and machine learning algorithms.

[0031] Beneficial effects of the present invention:

[0032] 1. The present invention can efficiently purify and disinfect:

[0033] Comprehensive removal of pollutants: The system integrates multi-layer composite filtration technology with a variety of advanced germ disinfecting technologies. The filtration unit can intercept large dust particles, fine particles, and absorb harmful gases and odors in turn through the primary filter, high-efficiency air filter and activated carbon filter, and comprehensively purify solid and some gaseous pollutants in the air. The germ disinfecting unit combines ultraviolet disinfection, plasma disinfection and photocatalytic disinfection technology to kill germs in all directions from different mechanisms of action. It can effectively remove various common germs in the air of wards, such as Escherichia coli, Staphylococcus aureus, influenza virus, etc., greatly reducing the risk of cross-infection and providing patients with a clean and healthy breathing environment.

[0034] Synergistic effect improves effect: The air circulation unit enables the air to form an effective circulation within the system, ensuring that the air can fully pass through the filtration and disinfection units. The units work together to significantly improve the purification and disinfection efficiency. Compared with a single technology or equipment, it can more thoroughly improve the air quality in the ward.

[0035] 2. The present invention can intelligently control:

[0036] Real-time adaptive adjustment: The central control module is based on a high-performance microprocessor and is equipped with an intelligent algorithm developed based on big data analysis and machine learning algorithms. It can receive and deeply analyze a large amount of data from the air detection module in real time, accurately judge the air quality and degree of pathogen contamination in the ward based on preset thresholds and complex models, and then dynamically and intelligently adjust the working mode of the purification and disinfection execution module. For example, when the concentration of pathogens is detected to be increased, the disinfection intensity is automatically increased; when the concentration of particulate matter increases, the filtering intensity is increased, so as to achieve real-time adaptive adjustment of purification and disinfection work, and effectively respond to the ever-changing air quality conditions in the ward.

[0037] Optimized utilization of resources: This intelligent control avoids the waste of resources caused by the fixed mode operation of traditional equipment. When the air quality is good, the system automatically reduces the operating power to reduce energy consumption and unnecessary wear and tear of equipment; when the air quality deteriorates, the purification and disinfection functions are enhanced in time to ensure the effect. It not only improves the efficiency of resource utilization, but also extends the service life of equipment and reduces the long-term use cost of the hospital.

[0038] 3. The present invention can monitor and alarm in real time:

[0039] Timely detection of abnormalities: The air detection module is equipped with high-precision pathogen concentration sensors, particulate matter sensors and volatile organic compound sensors, which can monitor the air quality parameters in the ward in real time and accurately, collecting data every 1 minute. High-frequency data collection ensures that subtle changes in air quality are captured in a timely manner. Once key parameters such as pathogen concentration, particulate matter concentration or VOC concentration are detected to exceed the set safety range, the sound and light alarm of the alarm module will immediately send out a strong sound and light signal, and the alarm information can be pushed to the medical staff's mobile terminal to ensure that the medical staff will be aware of the abnormal air quality at the first time.

[0040] Ensure health and safety: Real-time monitoring and rapid alarm mechanisms provide strong protection for the health and safety of medical staff and patients. Medical staff can take timely measures based on alarm information, such as strengthening ward cleaning and disinfection, isolating and observing patients, etc., to effectively prevent the spread of germs and avoid health risks caused by air quality problems.

[0041] 4. The present invention has data support and optimization:

[0042] In-depth data analysis: The data storage and analysis module uses large-capacity storage devices to store a large amount of air quality data for a long time, and uses advanced data analysis algorithms such as data mining, statistical analysis, and machine learning algorithms through the intelligent analysis module to conduct in-depth analysis of historical data. It can discover the trend of air quality changes, the laws of pathogen growth and spread, and the potential relationship between various factors, providing a scientific basis for hospital infection prevention and control.

[0043] Continuously optimize the system: Based on the data analysis results, the hospital can optimize the operating parameters of the purification and disinfection system in a targeted manner, such as adjusting the disinfection time and intensity, optimizing the filtering strategy, etc., to improve the system operation effect. At the same time, it also helps the hospital to formulate more forward-looking prevention and control measures, prevent the spread of germs in advance, continuously improve the ward air quality management system, and continuously improve the ward air quality.

DETAILED DESCRIPTION

[0053] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Example 1

[0055] like Figure 1 to Figure 2 As shown, an intelligent system for ward air purification and germ elimination includes:

[0056] Air detection module 1, which is designed to comprehensively and accurately monitor the air quality in the ward in real time;

[0057] Purification and disinfection execution module 2, which can realize efficient air purification and germ disinfection functions;

[0058] Alarm module 3, which can activate a full range of alarm mechanisms;

[0059] Central control module 4, which is responsible for receiving a large amount of real-time data from the air detection module, and using intelligent algorithms to conduct in-depth analysis, and sending corresponding control instructions to the purification and disinfection execution module and the intelligent alarm module, dynamically adjusting the purification and disinfection working mode and starting the alarm function;

[0060] Data storage and analysis module 5, which can store, manage and deeply analyze the massive data generated during the operation of the system;

[0061] The air detection module 1, the purification and disinfection execution module 2, the alarm module 3, and the data storage and analysis module 5 are respectively connected to the central control module 4;

[0062] The air detection module 1 contains a series of high-precision sensors;

[0063] The purification and disinfection execution module 2 includes a filter unit 201 , a germ disinfection unit 202 , and an air circulation unit 203 . The filter unit 201 is connected to the air circulation unit 203 via the germ disinfection unit 202 .

[0064] like Figure 3 As shown, a series of high-precision sensors include a pathogen concentration sensor 101, a particle sensor 102, and a volatile organic compound sensor 103. The pathogen concentration sensor 101 uses fluorescent quantitative PCR technology or immunofluorescence technology to detect the concentration of pathogens in the air, the particle sensor 102 measures the particle content through the laser scattering principle, and the volatile organic compound sensor 103 uses a semiconductor gas sensor to detect the VOC concentration.

[0065] The advantages of the above settings are:

[0066] Accurately detect germs

[0067] High sensitivity and specificity: The pathogen concentration sensor 101 uses fluorescent quantitative PCR technology or immunofluorescence technology, which has extremely high sensitivity and specificity for pathogen detection. Fluorescent quantitative PCR technology can accurately identify and quantify extremely small amounts of pathogens by amplifying and detecting specific nucleic acid sequences of pathogens, even if the concentration of pathogens in the air is extremely low. Immunofluorescence technology is based on the specific combination of antigens and antibodies, and uses fluorescent markers to intuitively display the presence and number of pathogens. It can accurately detect specific pathogens, such as Escherichia coli, Staphylococcus aureus, influenza virus, etc., and promptly discover potential sources of infection, buying time for preventing and controlling the spread of pathogens.

[0068] Fast and accurate: These two technologies have fast detection speeds and can produce results of pathogen concentration in a short time, providing a basis for medical staff to quickly judge the status of pathogen contamination in the ward so that timely measures can be taken to prevent the spread of pathogens.

[0069] Efficient detection of particulate matter

[0070] Accurately measure particle size and content: Based on the principle of laser scattering, the particle sensor 102 can not only detect the content of particles in the air, but also accurately measure the distribution of particles of different sizes. In the ward environment, it is very important to understand the concentration of particles of different sizes, because particles of different sizes have different effects on patients' health. For example, fine particles such as PM2.5 are more likely to enter the deep part of the human respiratory system and cause greater harm. Through accurate measurement, the potential threat of particles to the patient's respiratory tract can be evaluated.

[0071] Real-time monitoring of changes: This principle enables the sensor to monitor the dynamic changes of particulate matter content in real time, and promptly capture the fluctuations in particulate matter concentration caused by factors such as personnel activities and ventilation in the ward, providing real-time data support for the central control module 4 to adjust the purification strategy in a timely manner.

[0072] Sensitive detection of volatile organic compounds

[0073] Highly sensitive detection of harmful gases: Volatile organic compound sensor 103 uses semiconductor gas sensors and is highly sensitive to VOCs in the air. VOCs contain a variety of harmful gases, such as formaldehyde and benzene, and long-term exposure can harm the health of patients and medical staff. Semiconductor gas sensors can quickly sense the presence of these harmful gases and convert their concentration changes into electrical signal outputs, accurately detecting VOC concentrations and ensuring that the air quality in the ward meets health standards.

[0074] Adapt to complex environments: Semiconductor gas sensors have good stability and can work stably in the complex and changeable environment of the ward. They can adapt to changes in environmental factors such as temperature and humidity, continuously and reliably detect VOC concentrations, and provide accurate VOC data for the ward air purification and germ disinfection intelligent system.

[0075] Comprehensive assessment of air quality

[0076] Multi-dimensional data support: The three sensors detect germs, particulate matter and volatile organic compounds respectively, and comprehensively reflect the air quality status of the ward from different dimensions. These data are combined to provide rich information for the central control module 4, so that it can more accurately evaluate the air quality and formulate more scientific and reasonable purification and disinfection strategies. For example, when the concentration of germs is high and accompanied by high concentrations of VOCs, the disinfection and air purification efforts can be strengthened, and targeted measures can be taken to deal with harmful gases.

[0077] Prevent potential risks in advance: Through comprehensive testing, various potential risks that may affect patients' health, such as the risk of pathogen transmission and respiratory irritation, can be discovered in advance, helping medical staff to take preventive measures in advance to ensure the health and safety of patients and medical staff.

[0078] like Figure 4 As shown, the filter unit 201 includes a primary filter 2011 , the primary filter 2011 is connected to a high efficiency air filter 2012 , and the high efficiency air filter 2012 is connected to an activated carbon filter 2013 .

[0079] The advantages of the above settings are:

[0080] Gradual filtration to improve efficiency

[0081] Large particle pre-filtration: The primary filter 2011 is the first line of defense for the filtration unit, and can effectively intercept large particles of impurities, such as dust, hair, and dandruff. This not only prevents these large particles from entering the subsequent filters, reduces the burden on the high-efficiency air filter and activated carbon filter, but also extends their service life. At the same time, the rapid filtration of large particles by the primary filter 2011 allows the air to enter the subsequent filtration link more smoothly, ensuring the efficiency of the entire filtration process.

[0082] Fine particle filtration: The high-efficiency air filter 2012 is immediately connected to the primary filter 2011, and the filtration efficiency of particles larger than 0.3 microns can reach more than 99.97%. After the preliminary filtration of the primary filter 2011, the air entering the HEPA mainly contains fine particles. With its special fiber structure and manufacturing process, HEPA can efficiently capture these fine particles, such as PM2.5, etc., greatly reducing the content of suspended particles in the air, providing patients with clean air and reducing the risk of respiratory diseases.

[0083] Functional complementation, comprehensive purification

[0084] Adsorption of odor and harmful gases: The activated carbon filter 2013 is connected to the high-efficiency air filter 2012, and is mainly responsible for adsorbing odors and harmful volatile organic compounds such as formaldehyde and benzene in the air. Although the air filtered by the first two levels of filters has a significant reduction in particulate matter, it may still contain odors and harmful gases. The rich pore structure of the activated carbon filter 2013 gives it a strong adsorption capacity, which can effectively remove these odors and harmful gases, further improve the smell and chemical composition of the air, and create a fresh and healthy breathing environment for the ward.

[0085] Blocking the spread of germs: Some germs may attach to particulate matter or harmful gases to spread. The filtering of particulate matter by the primary filter 2011 and the high-efficiency air filter 2012, and the adsorption of harmful gases by the activated carbon filter 2013, block the transmission carriers of germs to a certain extent, reduce the probability of germs spreading in the air, and enhance the prevention and control capabilities of the entire purification system against germs.

[0086] Ensure stable operation of the system

[0087] Reduce equipment loss: The primary filter 2011 and the high-efficiency air filter 2012 effectively filter particulate matter, reducing the wear of particulate matter on air circulation equipment such as fans. At the same time, it also prevents the activated carbon filter 2013 from being blocked by particulate matter and affecting the adsorption effect, thereby extending the service life of the entire purification and disinfection system and reducing equipment maintenance costs.

[0088] Optimize air circulation: This hierarchical filtration setting allows the air to maintain a relatively stable and smooth flow rate and direction when passing through the filter unit. The primary filter 2011 initially organizes the airflow, the high-efficiency air filter 2012 further stabilizes the airflow, and the activated carbon filter 2013 absorbs harmful gases while ensuring the air circulation, ensuring that the purified air can be evenly and efficiently delivered back to various areas of the ward.

[0089] like Figure 5 As shown, the germ sterilization unit 202 includes an ultraviolet sterilization device 2021, a plasma sterilization device 2022, and a photocatalytic sterilization device 2023, and the ultraviolet sterilization device 2021 is connected to the photocatalytic sterilization device 2023 through the plasma sterilization device 2022.

[0090] The advantages of the above settings are:

[0091] Multiple disinfection mechanisms work together to improve the sterilization effect

[0092] Ultraviolet rays destroy the genetic material of germs: The ultraviolet disinfection device 2021 emits ultraviolet rays of a specific wavelength, which can directly act on the DNA or RNA of germs, destroy the structure of their genetic material, and make the germs lose their ability to reproduce and survive. This disinfection method has a significant effect on most germs and can inhibit the spread of germs from the root.

[0093] Plasma destroys the structure of bacteria: The plasma generated by the plasma disinfection device 2022 contains a large number of highly active particles. When these particles come into contact with bacteria, they can destroy the cell membrane and protein structure of the bacteria, causing the bacteria to die. Combined with ultraviolet disinfection, it strikes bacteria from different levels, increasing the comprehensiveness and thoroughness of disinfection.

[0094] Photocatalytic oxidation to decompose germs: The photocatalytic disinfection device 2023 uses the strong oxidizing substances produced by photocatalysts under ultraviolet light to non-selectively decompose germs and organic pollutants, converting them into harmless substances such as carbon dioxide and water. This can not only disinfect germs, but also further purify the residual organic pollutants in the air, and cooperate with the first two disinfection methods to achieve deep purification of germs and pollutants.

[0095] Adapt to the characteristics of different pathogens and expand the scope of disinfection

[0096] Complementary advantages for different pathogens: Different pathogens have different sensitivities to different disinfection methods. For example, some viruses may be more sensitive to ultraviolet rays, while some bacteria may be more susceptible to the destructive effects of plasma. The combination of three disinfection devices can adapt to the characteristics of a variety of pathogens, expand the disinfection range of various pathogens, and ensure that common pathogens in ward air, such as Escherichia coli, Staphylococcus aureus, influenza virus, etc., can be effectively killed.

[0097] Dealing with pathogen mutations: In a medical environment, pathogens may mutate, and a single disinfection method may become ineffective due to pathogen mutations. However, the coexistence of multiple disinfection mechanisms can still disinfect the pathogens through different modes of action even if the pathogens mutate to a certain extent, thus improving the system's ability to deal with pathogen mutations and ensuring the stability of the disinfection effect.

[0098] Improve air purification efficiency and optimize environmental quality

[0099] Continuous air purification: The three disinfection devices are connected in sequence, so that the air is continuously disinfected and purified in different ways during the flow. The air is first disinfected by ultraviolet rays, then by plasma, and finally by photocatalysis. In this continuous process, germs and pollutants are continuously removed, which improves the efficiency of air purification and ensures that the air delivered reaches a higher degree of cleanliness.

[0100] Reduce secondary pollution: The photocatalytic disinfection device can not only decompose the bacteria, but also treat the organic pollutants in the air, thus avoiding the secondary pollution caused by the debris or substances released after the bacteria are killed. At the same time, the active particles generated during the plasma disinfection process also help to decompose the harmful gases in the air, further optimizing the air quality of the ward.

[0101] Enhance system stability and reliability

[0102] Disperse equipment pressure: Distribute the disinfection tasks to three different devices. Each device only needs to focus on the disinfection mechanism it is good at, which reduces the workload of a single device, reduces the probability of equipment failure due to long-term high-load operation, and improves the stability and reliability of the entire germ disinfection unit.

[0103] Mutual backup protection: In actual operation, if one of the disinfection devices fails, the other two devices can still continue to play a certain disinfection role, providing basic safety protection for the ward air, and will not cause the entire disinfection system to fail completely, ensuring that the system can maintain a certain pathogen prevention and control capability under various circumstances.

[0104] like Figure 5 As shown, the ultraviolet disinfection device 2021 includes a first ventilation pipe 20211, in which a plurality of groups of evenly distributed deep ultraviolet LED lamps 20212 are connected, the plasma disinfection device 2022 includes a second ventilation pipe 20221 connected to the first ventilation pipe 20211, in which a plasma discharger 20222 is connected, and the photocatalytic disinfection device 2023 includes a third ventilation pipe 20231 connected to the second ventilation pipe 20221, in which a photocatalyst box 20232 and an ultraviolet irradiation lamp 20233 corresponding to the photocatalyst box 20232 are connected.

[0105] The advantages of the above settings are:

[0106] Enhanced disinfection effect

[0107] Uniform ultraviolet coverage: The ultraviolet disinfection device 2021 is equipped with multiple groups of evenly distributed deep ultraviolet LED lamps 20212 in the first ventilation duct 20211, which can ensure that all parts of the air can be fully exposed to ultraviolet rays when passing through the ventilation duct, causing comprehensive damage to the DNA or RNA of pathogens, effectively killing pathogens in the air, and greatly improving the effect and range of ultraviolet disinfection.

[0108] Progressive disinfection synergy: The air after ultraviolet disinfection directly enters the second ventilation pipe 20221 of the plasma disinfection device 2022. The plasma generated by the plasma discharger 20222 can further destroy the cell membrane and protein structure of the bacteria. This progressive disinfection setting greatly increases the probability of killing the bacteria after continuous attacks by different mechanisms of action. Subsequently, the air enters the photocatalytic disinfection device 2023, and the light emitted by the ultraviolet irradiation lamp 20233 excites the photocatalyst in the photocatalyst box 20232 to produce strong oxidizing substances, which again decompose the bacteria and residual organic pollutants. The three layers of disinfection work closely together, significantly enhancing the overall disinfection effect.

[0109] Air purification process optimization

[0110] Continuous air flow path: The first ventilation pipe 20211, the second ventilation pipe 20221 and the third ventilation pipe 20231 are connected in sequence, providing a smooth and continuous purification path for the air. The air does not need to be complicatedly turned or redistributed during the flow process, which reduces energy loss and air flow turbulence, ensures that the air can pass through each disinfection device in sequence at a stable flow rate and flow rate, and improves the purification efficiency.

[0111] Efficient space utilization: Each disinfection device is set up based on the ventilation pipe, with a compact structure, and realizes the integration of multiple disinfection technologies in a limited space. This design not only meets the ward’s demand for small equipment space, but also ensures the orderly implementation of different disinfection functions and optimizes the spatial layout of the equipment.

[0112] The equipment operates stably and reliably

[0113] Modular design facilitates maintenance: Each disinfection device is relatively independent and interconnected to form a modular structure. When a device fails, it is easy to repair or replace it separately without affecting the normal operation of other devices. For example, if the deep ultraviolet LED lamp 20212 is damaged, it can be directly repaired or replaced in the first ventilation duct 20211 without interfering with the work of the plasma disinfection device 2022 and the photocatalytic disinfection device 2023, reducing maintenance costs and difficulties and improving the operational stability of the entire system.

[0114] Targeted component configuration: Corresponding disinfection components are configured in each ventilation duct in a targeted manner, such as setting a plasma discharger 20222 in the second ventilation duct 20221, and setting a photocatalyst box 20232 and an ultraviolet lamp 20233 in the third ventilation duct 20231. This precise configuration enables each component to perform at its best in its appropriate environment, ensuring the reliability and stability of the equipment operation.

[0115] like Figure 6As shown, the air circulation unit 203 includes a fourth ventilation pipe 2031 connected to the third ventilation pipe 20231 , and the fourth ventilation pipe 2031 is connected to a high-performance fan 2032 .

[0116] The advantages of the above settings are:

[0117] Ensure effective air circulation

[0118] Providing strong power: The high-performance fan 2032 provides stable and strong power for air circulation, which can promote the rapid flow of air in the ward and form a continuous and effective circulation. This allows the clean air that has been purified and disinfected to be quickly transported to every corner of the ward, while the polluted air is promptly introduced into the purification and disinfection unit, ensuring the efficient air purification and germ disinfection process. In a relatively closed space such as a ward, good air circulation can avoid large differences in local air quality and provide patients with an overall healthy breathing environment.

[0119] Maintaining air circulation stability: The connection design between the fan and the ventilation pipe ensures the stability of the air during the circulation process. The fourth ventilation pipe 2031 is smoothly connected to the third ventilation pipe 20231, which reduces the resistance and turbulence of air flow, allowing the air to flow smoothly along the predetermined path and evenly return to the ward after passing through the purification and disinfection unit. This stable air circulation helps to improve the working efficiency of the purification and disinfection system and ensure that the entire system can operate continuously and stably.

[0120] Improve purification and disinfection efficiency

[0121] Fully utilize the purification and disinfection unit: The setting of the air circulation unit 203 allows the air to fully contact the filter unit 201 and the germ disinfection unit 202. Through continuous circulation, more air can pass through the primary filter 2011, the high-efficiency air filter 2012, the activated carbon filter 2013, the ultraviolet disinfection device 2021, the plasma disinfection device 2022 and the photocatalytic disinfection device 2023 within a certain period of time, so that these purification and disinfection equipment can fully play their role and improve the removal effect of germs, particulate matter and harmful gases. For example, air that may originally take a long time to purify can complete the purification process faster under the action of efficient air circulation, thereby improving the overall purification and disinfection efficiency.

[0122] Accelerate the purification process: Rapid air circulation shortens the time that air stays in the ward, reducing the chances of germs spreading and growing in the air. At the same time, timely delivery of purified air back to the ward can also improve the air quality in the ward more quickly, providing patients with more timely health protection. In the case of high germ concentrations, efficient air circulation can quickly reduce the concentration of germs in the air, effectively preventing the spread and diffusion of germs.

[0123] Enhance system adaptability

[0124] Adapt to different ward environments: The high-performance fan 2032 can flexibly adjust the wind speed according to the size, layout and actual needs of the ward. For wards with larger areas, the fan power can be increased to ensure that the air can be effectively circulated to every corner; for smaller wards, the power can be appropriately reduced to reduce energy consumption while ensuring the air circulation effect. This flexibility enables the air circulation unit 203 to adapt to ward environments of different types and sizes, improving the versatility and adaptability of the entire purification and disinfection system.

[0125] Responding to different air quality conditions: When the air detection module 1 detects that the air quality in the ward is poor, such as high pathogen concentration, particulate matter concentration or VOC concentration, the central control module 4 can adjust the speed of the high-performance fan 2032 to speed up the air circulation speed, so that the purification and disinfection unit can process the air more frequently, thereby more effectively responding to changes in air quality and ensuring that the air quality in the ward is always good.

[0126] The alarm module 3 is an audible and visual alarm.

[0127] The advantages of the above settings are:

[0128] Intuitive and eye-catching, timely reminder

[0129] Visual and auditory dual stimulation: The sound and light alarm can attract the attention of medical staff at the first time by emitting strong flashing light and loud sound. In the complex environment of the ward, medical staff may be busy with multiple tasks at the same time. A simple sound alarm may be masked by the surrounding noise, and a simple light alarm may be ignored due to the obstruction of vision. The sound and light alarm combines the two. Whether it is day or night, no matter where the medical staff is in the ward, they can easily detect the alarm, ensuring that they can respond to abnormal air quality in time.

[0130] Quickly locate abnormalities: Strong flashing lights and loud sounds can help medical staff quickly locate the ward where the alarm is issued. In large places such as hospitals, when multiple wards may have various situations at the same time, sound and light alarms can allow medical staff to quickly determine the problem, save time in finding the source of the abnormality, and take appropriate measures in a timely manner.

[0131] Simple, reliable and cost-effective

[0132] Simple structure and easy maintenance: The structure of the sound and light alarm is relatively simple, and its main components are the light-emitting device and the sound-emitting device. Compared with some complex alarm devices, the probability of failure is lower. Daily maintenance is also relatively convenient. You only need to regularly check whether the light is flashing normally and whether the sound is clear and loud. If there is a problem, just replace the corresponding parts, which reduces maintenance costs and technical difficulties.

[0133] Low cost: The manufacturing cost of the sound and light alarm is relatively low. While meeting the alarm needs of the ward air purification and germ disinfection intelligent system, it will not bring excessive equipment procurement costs to the hospital. For places like hospitals that require a large number of related equipment, choosing cost-effective sound and light alarms can help control the overall budget.

[0134] Wide applicability and compatibility

[0135] Adaptable to various environments: The sound and light alarm can work normally under various environmental conditions, whether it is a ward with large temperature and humidity changes, or near medical equipment with certain electromagnetic interference, it can stably send out alarm signals. It has strong adaptability to the environment, ensuring that the alarm function can be reliably played in different ward environments.

[0136] Easy to integrate into the system: The sound and light alarm can be easily integrated with the entire intelligent system. It can receive the alarm instructions sent by the central control module, respond in time, and work together with other modules of the system to form a complete air monitoring and alarm system to ensure the efficient operation of the ward air quality monitoring and response mechanism.

[0137] The central control module 4 is based on a high-performance microprocessor and is equipped with intelligent algorithms developed based on big data analysis and machine learning algorithms. The central control module 4 is connected to the hospital information system.

[0138] The advantages of the above settings are:

[0139] Intelligent and accurate decision-making

[0140] In-depth data analysis: With a high-performance microprocessor as the core, it has powerful data processing capabilities and can quickly receive and process a large amount of real-time data from the air detection module. The intelligent algorithm developed based on big data analysis and machine learning algorithms can conduct in-depth mining and analysis of these data. For example, by analyzing the correlation between multi-dimensional data such as pathogen concentration, particulate matter concentration, and volatile organic compound concentration, as well as their changing trends over time, the air quality status and degree of pathogen pollution in the ward can be accurately judged, providing a scientific basis for subsequent decision-making.

[0141] Intelligent dynamic control: Based on the results of data analysis, the intelligent algorithm can adjust the working mode of the purification and disinfection execution module in real time. When the concentration of pathogens increases, the disinfection intensity is automatically increased, such as increasing the working time of the ultraviolet disinfection device and increasing the power of the plasma disinfection device; when the air quality is good, the equipment operation intensity is reduced to achieve energy saving and consumption reduction. This intelligent dynamic control enables the system to be flexibly adjusted according to actual conditions to ensure that it always operates in the best state, improve the purification and disinfection effect, and optimize resource utilization efficiency.

[0142] Improving the level of medical informationization

[0143] Information interconnection: The central control module is connected to the hospital information system, realizing the interconnection of ward air quality data with the overall hospital information. Medical staff can view the real-time data of ward air quality anytime and anywhere through the hospital internal network or mobile terminals, without having to check on-site in the ward, which improves work efficiency. At the same time, these data can also provide reference for the overall management and decision-making of the hospital, such as reasonably arranging the use of wards and adjusting the protective measures for medical staff.

[0144] Assisting medical decision-making: Air quality data combined with other medical information in the hospital can help doctors understand the patient's treatment environment more comprehensively and provide a reference for diagnosis and treatment. For example, when it is found that the air quality in a ward is continuously poor and the patient's condition is abnormal, the doctor can consider the impact of air quality factors on the patient's condition and adjust the treatment plan. In addition, the long-term accumulation of air quality data can also be used to study the relationship between air quality and patient recovery, providing data support for improving the hospital's medical quality.

[0145] System optimization and continuous improvement

[0146] Predictive maintenance: Through long-term analysis of system operation data, machine learning algorithms can predict possible equipment failures. For example, based on the operation time, working intensity and performance data of related components of the purification and disinfection equipment, potential failure hazards can be discovered in advance, and maintenance personnel can be reminded to perform maintenance or replace components in a timely manner to avoid sudden equipment failures that affect the air quality in the ward, ensure the stable operation of the system, and reduce maintenance costs.

[0147] Optimize prevention and control strategies: Big data analysis can help hospitals summarize the air quality changes and pathogen transmission characteristics of wards in different seasons and departments. Based on these rules, hospitals can formulate more targeted infection prevention and control strategies and take preventive measures in advance, such as strengthening the disinfection of specific wards during the high-incidence season of pathogens, optimizing ward ventilation plans, etc., to continuously improve the level of hospital infection prevention and control.

[0148] like Figure 7As shown, the data storage and analysis module 5 includes a large-capacity storage device 501 , and the large-capacity storage device 501 is connected to an intelligent analysis module 502 .

[0149] The advantages of the above settings are:

[0150] Long-term stable data storage

[0151] Massive data carrying: The large-capacity storage device 501 can meet the massive data storage requirements generated by the long-term operation of the system. The data such as the pathogen concentration, particulate matter content, and volatile organic matter concentration monitored in real time by the air detection module 1, as well as the operating status data of the purification and disinfection execution module 2, need to be stored for a long time. Whether it is a high-performance hard disk array or a cloud storage service, the large-capacity storage device 501 has a strong storage capacity to ensure that data is not lost, providing rich data resources for subsequent analysis and research.

[0152] Data security and reliability: High-performance hard disk arrays usually have redundant designs, such as RAID technology, which can ensure data integrity and availability when some hard disks fail. Cloud storage services have professional data centers and backup mechanisms, providing multiple data backup and disaster recovery solutions to prevent data loss due to natural disasters, hardware failures and other unexpected situations. This provides a strong guarantee for the safe storage of system data, allowing hospitals to safely accumulate and use this data for a long time.

[0153] In-depth data analysis and mining

[0154] Discovering potential patterns: The intelligent analysis module 502 uses advanced data analysis algorithms, such as data mining, statistical analysis, and machine learning algorithms, to deeply analyze the historical data stored in the large-capacity device 501. Through analysis, potential patterns of changes in air quality can be discovered, such as the changing trend of pathogen concentration in different seasons and time periods, and the correlation with factors such as ward personnel flow and ventilation conditions. These patterns help hospitals take targeted measures in advance to prevent the spread of pathogens and the deterioration of air quality.

[0155] Evaluate system performance: By analyzing the operation data of the purification and disinfection execution module 2, the intelligent analysis module 502 can evaluate the operation effect of the system. For example, analyze the working efficiency of different filter units 201 and germ disinfection units 202 to determine whether the expected purification and disinfection indicators are achieved. According to the evaluation results, the system parameters can be adjusted in time or the equipment can be maintained and upgraded to ensure that the system always maintains the best operating state and improves the effect of air purification and germ disinfection.

[0156] Assist decision making and optimize management

[0157] Formulate scientific prevention and control strategies: Based on the results of data analysis, hospital managers can formulate more scientific and reasonable ward infection prevention and control strategies. For example, according to the air quality data of different wards and the risk assessment of pathogen transmission, human and material resources can be reasonably allocated to strengthen monitoring and disinfection of high-risk wards. At the same time, according to the data prediction results, corresponding protective materials and medicines can be reserved in advance to improve the ability to respond to emergencies.

[0158] Optimize resource allocation: The intelligent analysis module 502 can help hospitals optimize the resource allocation of the purification and disinfection system. By analyzing the air quality requirements for equipment operation in different time periods, the equipment operation time and intensity can be reasonably adjusted to avoid unnecessary energy consumption and equipment loss, thereby reducing operating costs. For example, at night when there are fewer people in the ward and the air quality is relatively good, the operating power of the purification and disinfection equipment can be appropriately reduced to achieve a balance between energy saving and efficient operation.

[0159] Supporting scientific research and quality improvement

[0160] Assisting medical research: The long-term accumulated air quality and pathogen data provide valuable materials for medical research. Researchers can use this data to study the relationship between ward environment and disease transmission and explore new prevention and control methods and technologies. For example, studying the transmission mechanism of specific pathogens under different air quality conditions can provide a theoretical basis for the development of more effective prevention and control measures.

[0161] Continuous quality improvement: The data support provided by the data storage and analysis module 5 helps the hospital to continuously improve the air quality management of wards. By regularly analyzing data, summarizing lessons learned, discovering deficiencies in the management process, and adjusting management methods and processes in a timely manner, the level of ward air quality management can be continuously improved to provide patients with a better quality and safer treatment environment.

[0162] A further solution of the present invention is that the large-capacity storage device 501 is a high-performance hard disk array or a cloud storage service, and the intelligent analysis module 502 is an analysis module that uses advanced data analysis algorithms, and the data analysis algorithms include but are not limited to data mining, statistical analysis and machine learning algorithms.

[0163] The advantages of the above settings are:

[0164] Advantages of Mass Storage Devices

[0165] High-performance hard disk array

[0166] High-speed reading and writing: The high-performance hard disk array uses multiple hard disks to work in parallel. Through RAID technology, the reading and writing speed of data can be significantly improved. In the ward air purification and germ disinfection intelligent system, the data generated by the air detection module 1 needs to be stored quickly, and the intelligent analysis module 502 also needs to read historical data quickly when performing data analysis. High-speed reading and writing capabilities ensure real-time storage and rapid call of data, ensuring efficient operation of the system.

[0167] Data redundancy and fault tolerance: RAID technology uses data redundancy mechanisms such as mirroring and parity checking to ensure that data will not be lost even if some hard disks fail. This is crucial for scenarios such as wards that require extremely high data integrity, ensuring the reliability of long-term stored air quality and equipment operation data, and providing a solid foundation for subsequent analysis and decision-making.

[0168] Local control and security: With data centers deployed locally in hospitals, hospitals can directly control data storage, and data security and privacy are more guaranteed. For sensitive data related to patient health, the security risks that may be caused by data transmission and storage in the cloud are reduced, meeting the strict requirements of the medical industry for data security.

[0169] Cloud storage services

[0170] Scalability: Cloud storage has unlimited expansion potential. As the number of wards increases and the amount of monitoring data increases, there is no need to worry about insufficient storage space. Hospitals can flexibly adjust storage capacity according to actual needs, avoiding the high cost and complex operations caused by hardware upgrades, ensuring that the system can operate stably in the long term and adapt to the future development of the hospital.

[0171] Cost-effectiveness: Compared with the hardware procurement, computer room construction, power consumption and personnel maintenance costs required to build and maintain local high-performance hard disk arrays, cloud storage services adopt a pay-as-you-go model, which greatly reduces the hospital's initial investment and operating costs. This low-cost storage solution is particularly attractive to medical institutions with limited budgets.

[0172] Data sharing and remote access: Medical staff and managers can access data stored in the cloud through the Internet anywhere with a network connection, which facilitates remote monitoring and management. Data can also be easily shared between different hospital campuses, promoting the integration and collaboration of medical resources and improving the overall efficiency of medical services.

[0173] Advantages of the intelligent analysis module

[0174] Data Mining Algorithms

[0175] Discover hidden patterns: Data mining algorithms can discover potential patterns and regularities from massive amounts of air quality and pathogen data. For example, they can discover the complex relationship between pathogen transmission and air quality factors in different seasons and ward types. This hidden information is crucial for developing targeted prevention and control strategies, helping hospitals prevent pathogen transmission in advance and optimize air purification and disinfection programs.

[0176] Anomaly detection: By learning from historical data, data mining algorithms can identify data points that do not conform to normal patterns, i.e. anomalies. For example, if a sudden surge in pathogen concentration or abnormal fluctuations in purification equipment operating parameters are detected in air quality data, early warnings can be issued in a timely manner, allowing hospitals to take prompt measures to prevent the spread of potential infection risks.

[0177] Statistical analysis algorithms

[0178] Quantification of data features: Statistical analysis algorithms can quantify air quality data and calculate statistical indicators such as mean, standard deviation, and correlation. Through these indicators, hospitals can clearly understand the overall status and changing trends of air quality and evaluate the effectiveness of the purification and disinfection system. For example, by comparing the mean values ​​of pathogen concentrations in different time periods, it can be determined whether prevention and control measures are effective.

[0179] Risk assessment: Use statistical analysis methods to assess the risk of pathogen transmission, establish risk models based on historical data, and predict possible air quality problems and pathogen transmission risks in the future, providing a scientific basis for hospitals to formulate response strategies in advance, reasonably allocate resources, and improve the initiative and effectiveness of prevention and control work.

[0180] Machine Learning Algorithms

[0181] Intelligent prediction: Machine learning algorithms can build prediction models by learning from a large amount of historical data to predict future changes in air quality and the spread of pathogens. For example, based on time series analysis, the future trend of pathogen concentration can be predicted to help hospitals prepare in advance, such as increasing the frequency of disinfection and stockpiling protective materials, to effectively respond to potential air quality crises.

[0182] Adaptive optimization: With the continuous influx of new data, the machine learning algorithm can automatically update the model and continuously optimize the analysis results. During the operation of the system, the control strategy of the purification and disinfection equipment is adjusted according to real-time data, so that the system can adapt to the dynamic changes of the ward environment, always maintain the best operating state, and improve the intelligent level of air purification and germ disinfection.

[0183] Working principle:

[0184] Real-time monitoring of air detection module 1: air detection module 1 includes pathogen concentration sensor 101, particle sensor 102 and volatile organic compound sensor. Pathogen concentration sensor 101 uses fluorescence quantitative PCR technology or immunofluorescence technology to detect nucleic acid or antigen of specific pathogens such as Escherichia coli, Staphylococcus aureus, influenza virus, etc. in the air, so as to accurately obtain the concentration of pathogens. Particle sensor 102 is based on the principle of laser scattering. When the laser irradiates the particles in the air, scattered light will be generated. By analyzing the intensity and angle of the scattered light, the particle size and number of the particles are calculated to measure the particle content. Volatile organic compound sensor 103 uses semiconductor gas sensors. When VOC exists in the air, the resistance of the gas sensor will change, and the concentration of VOC is determined by detecting the change in resistance. These sensors collect data every 1 minute and transmit real-time data to the central control module 4.

[0185] Intelligent analysis and decision-making of the central control module 4: The central control module 4 is based on a high-performance microprocessor and is equipped with an intelligent algorithm developed based on big data analysis and machine learning algorithms. After receiving the data from the air detection module 1, the intelligent algorithm compares and analyzes these real-time data with the preset threshold and the pathogen pollution degree assessment model. For example, when the pathogen concentration is higher than a certain threshold, and the particle concentration and VOC concentration are also beyond the normal range, it is judged that the air quality in the ward is poor and the degree of pathogen pollution is high. Based on this analysis result, the central control module 4 sends corresponding control instructions to the purification and disinfection execution module 2, such as adjusting the intensity, time and other parameters of purification and disinfection; at the same time, if the air quality is judged to be abnormal, it will also send instructions to the alarm module 3 to start the alarm. In addition, the central control module 4 is connected to the hospital information system, and medical staff can obtain ward air quality data in real time through the hospital internal network or mobile terminal, and remotely adjust the system operation parameters.

[0186] Purification and disinfection execution module 2 efficient operation:

[0187] Filter unit 201 purifies layer by layer: air first enters filter unit 201, and primary filter 2011 intercepts large dust particles, hair and other impurities, reducing the burden of subsequent filters. Then, the air passes through high-efficiency air filter 2012, which has a filtration efficiency of more than 99.97% for particles larger than 0.3 microns, and can effectively remove fine particles. Finally, activated carbon filter 2013 absorbs odors and harmful gases such as formaldehyde and benzene in the air, further improving air quality.

[0188] The germ disinfecting unit 202 uses multiple technologies in coordination: the filtered air enters the germ disinfecting unit 202, and the deep ultraviolet LED lamp in the ultraviolet disinfecting device 2021 emits ultraviolet rays with a wavelength of 200-280 nanometers, destroying the DNA or RNA structure of the germs, making them lose their ability to reproduce and survive. The plasma disinfecting device 2022 generates plasma through the plasma discharger 20222, and the active particles therein come into contact with the germs, destroying the cell membrane and protein structure of the germs to achieve sterilization. In the photocatalytic disinfecting device 2023, the ultraviolet irradiation lamp 20233 irradiates the photocatalyst in the photocatalyst box 20232, generating electron-hole pairs, which react with water and oxygen in the air to generate hydroxyl free radicals with strong oxidizing properties, decomposing germs and organic pollutants. These three disinfecting technologies cooperate with each other to kill germs in the air in all directions.

[0189] The air circulation unit 203 provides power and circulation: The high-performance fan 2032 of the air circulation unit 203 provides power for air flow, so that the air in the ward forms a circulation. The air flows in the air duct, passes through the filter unit 201 and the germ disinfecting unit 202, and is sent back to various areas of the ward through the fourth ventilation pipe 2031 to ensure uniform air quality in the ward. The guide plate in the air duct optimizes the air flow path, allowing the air to pass through each unit more evenly, thereby improving the purification and disinfecting efficiency.

[0190] Timely warning by alarm module 3: When the alarm module 3 receives the alarm command from the central control module 4, the sound and light alarm installed in a conspicuous position in the ward immediately sends out a strong sound and light signal to attract the attention of medical staff. At the same time, the alarm information is integrated with the hospital information system and pushed to the mobile terminals of medical staff, such as mobile phones and tablet computers, so that medical staff can understand the abnormal air quality in time and take corresponding measures.

[0191] The data storage and analysis module 5 provides support: The large-capacity storage device 501 of the data storage and analysis module 5 stores the air quality data transmitted by the air detection module 1 in real time. The intelligent analysis module 502 uses algorithms such as data mining, statistical analysis and machine learning to conduct in-depth analysis of historical data and generate air quality reports. By analyzing the data, the operating effect of the purification and disinfection system can be evaluated, the trend of air quality changes and the law of bacterial growth and transmission can be discovered, and strong data support can be provided for optimizing system operating parameters and formulating infection prevention and control strategies for hospitals.

[0192] The examples given in the present invention are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
