[0023] The present application relates to chamber systems.

[0024] The chamber system according to the present application can be a device that can be used in studies on the effects of pollutants on organisms.

[0025] Figure 1 is a structural diagram of a chamber system according to an embodiment of the present application.

[0026] The chamber system according to the present application includes: a chamber 100 , a supply unit 200 , a monitoring unit 300 , and an analyzing unit 400 .

[0027] Chamber 100 has a space for accommodating an organism. The organisms are not limited to bacteria, insects, animals, plants, etc., but may also include human skin tissue or organ tissue that can respond to external stimuli. Chamber 100 can be designed to an appropriate size based on the size of the organism.

[0028] Furthermore, the chamber 100 can be made of or coated with a material that is low in contaminants and reactivity. The material can be, for example, Teflon.

[0029] The chamber 100 may include a heater for supplying heat to the receiving space, a dehumidifier for removing moisture from the receiving space, and a temperature and humidity controller for controlling the operation of the heater and the dehumidifier to adjust the temperature and humidity of the receiving space. In addition, the chamber 100 may further include a lighting device.

[0030] In addition, the chamber 100 may be provided with an alarm device for detecting excessive temperature changes or gas leaks and notifying the outside world.

[0031] Furthermore, in order to facilitate observation of the accommodation space from the outside, the chamber 100 may be made of a transparent material or be provided with a transparent window.

[0032] Supply unit 200 supplies sample aerosol to the organism within the containment space. Supply unit 200 is the sample aerosol supply unit. In the present invention, sample aerosol refers to solid particles, liquid particles (also known as liquid particles), or composite particles of liquid and solid particles enriched in the air.

[0033] In the present invention, the sample aerosol may refer to aerosols generated in daily environments (eg, aerosols generated during cooking) to specific environments (eg, aerosols generated during welding), and may also refer to aerosols produced by copying.

[0034] The supply unit 200 can supply sample aerosol to the organism in the containing space through a mechanical atomizer, a nebulizer, an impinger, a mechanical sprayer, an ultrasonic sprayer, an electrostatic sprayer, or a pneumatic dust dispenser.

[0035] The supply unit 200 may include a supply quantity adjustment unit for adjusting the supply quantity of the sample aerosol. The supply quantity adjustment unit may control the concentration of the sample aerosol in the receiving space by adjusting the supply quantity of the sample aerosol.

[0036] Furthermore, the supply unit 200 can adjust the frequency of sample aerosol supply. For example, the supply unit 200 can supply sample aerosol a certain number of times within a period of time. By adjusting the sample aerosol supply frequency, the analysis unit 400 can help determine the impact of acute, subchronic, and chronic exposure to sample aerosol on the pro- or anti-functional health of an organism.

[0037] The monitoring unit 300 monitors changes in the movement or image of the organism before and after the sample aerosol is supplied. For example, the monitoring unit 300 may include a camera for imaging the organism and a storage unit for storing images captured by the camera. The camera can be a high-resolution camera, an infrared camera, or other types of cameras. In particular, an infrared camera can determine changes in the organism's body temperature.

[0038] In addition, the monitoring unit 300 includes various markers for detecting changes in the movement, heart rate, respiratory rate, body temperature, etc. of the living body, and the markers can be attached to the living body.

[0039] The monitoring unit 300 may monitor behavioral changes of the organism before and after exposure to the sample aerosol, or monitor changes in body temperature, shape, or color of a surface portion of the organism.

[0040] For example, the monitoring unit 300 can use a heat map to monitor behavioral changes of an organism. Specifically, the monitoring unit (300) can convert a room into a 2D or 3D map to generate a virtual map, and display the movement path of the organism or the time it stays at a specific location in the generated virtual map to monitor behavioral changes of the organism.

[0041] For example, the monitoring unit 300 can work in conjunction with a cloud-based system to allow users to remotely access and analyze data. In this way, users can confirm the progress of the experiment anytime and anywhere and take immediate action if necessary.

[0042] The analysis unit 400 analyzes the biological correlation between the sample aerosol and the organism based on the monitoring results. The biological correlation may include various analysis objects such as physiological reactions, genetic changes, and biochemical reactions.

[0043] The analysis unit 400 can analyze the patterns of movement changes or image changes of the organism before and after exposure to the sample aerosol, and accurately analyze the impact of the particle size, type, chemical properties, exposure time, etc. of the sample aerosol on the behavior, growth, health status, etc. of the organism from the pattern analysis.

[0044] In addition, the analysis unit 400 can analyze the effects of the sample aerosol on pro-functional or anti-functional health.

[0045] For example, the analysis unit 400 can analyze acute, subchronic, and chronic diseases of an organism caused by exposure to the sample aerosol. Examples of the diseases include respiratory diseases, cardiovascular diseases, cerebrovascular diseases, lung diseases, endocrine diseases, blood diseases, liver diseases, obesity, mental illnesses, urinary system diseases, genital diseases, neurological diseases, autoimmune diseases, genetic diseases, skin diseases, eye diseases, periodontal diseases, and behavioral disorders.

[0046] The analysis unit 400 may perform analysis by applying a learning algorithm based on deep learning.

[0047] In addition, the analysis unit 400 can analyze the influence on the behavior, growth, health status, etc. of the organism based on the concentration of the sample aerosol.

[0048] In addition, the analysis unit 400 may analyze the influence on the behavior, growth, health status, etc. of the organism according to the supply frequency of the sample aerosol.

[0049] In one example, the sample aerosol may include at least one of the following particles: solid particles, liquid particles, and composite particles of liquid particles and solid particles. The sample aerosol may contain a rich amount of the above particles in the air.

[0050] Solid particles may include metal particles or non-metal particles. Examples of metal particles include iron particles, aluminum particles, and lead particles, and examples of non-metal particles include silicon dioxide particles, latex particles, and carbon-based particles.

[0051] Liquid particles may include, for example, organic compounds, inorganic compounds, or mixtures thereof. Examples of organic compounds include alcohols, ketones, esters, etc., and examples of inorganic compounds include sodium hydroxide, potassium hydroxide, sulfuric acid, etc.

[0052] As an example, liquid particles can include various natural substances found in daily life or their imitations. Imitations are artificially manufactured substances that resemble natural substances. For example, liquid particles can include oil droplets such as oil mist produced during cooking, volatile organic compound droplets formed by condensation after evaporation of volatile organic compounds, and water-soluble droplets formed by condensation of water-soluble substances such as nitrogen oxides and sulfur oxides in the air and dissolving in water.

[0053] In addition, the composite particles can have a core-shell structure in which liquid particles surround solid particles.

[0054] In a specific example, the supply unit 200 may include a first supply unit 210 supplying a first sample aerosol including solid particles, a second supply unit 220 supplying a second sample aerosol including liquid particles, and a third supply unit 230 supplying a third sample aerosol including composite particles.

[0055] In one example, the supply unit 200 may include a manufacturing unit for manufacturing a sample aerosol. The manufacturing unit may be a separate device from the supply unit 200 or integrated with the supply unit 200. If the manufacturing unit and the supply unit 200 are integrated, the sample aerosol may be manufactured on a single device and then supplied to the organism within the containment space.

[0056] The first supply unit 210 may include a first manufacturing unit 210 that manufactures a first sample aerosol including solid particles, the second supply unit 220 may include a second manufacturing unit 220 that manufactures a second sample aerosol including liquid particles, and the third supply unit 230 may include a third manufacturing unit 230 that manufactures a third sample aerosol including composite particles. The first manufacturing unit 210 may include a spark spray device, the second manufacturing unit 220 may include a micronizer or an atomizer, and the third manufacturing unit 230 may include a spark spray device, a micronizer, or an atomizer.

[0057] In the present invention, the first to third supply parts and the first to third manufacturing parts are respectively understood as integrated equipment and represented by the same symbols, but are not limited to this. The first to third supply parts and the first to third manufacturing parts can be different equipment separated from each other.

[0058] In addition, the first to third manufacturing units 210, 220, and 230 may include a gas supply device for supplying gas such as air, and the particles manufactured in the first to third manufacturing units 210, 220, and 230 may be mixed with the gas supplied from the gas supply device to be manufactured in the form of aerosol.

[0059] In the third production unit 230 , solid particles produced by spark blasting may be combined with liquid particles generated by a micronizer or an atomizer to form composite particles.

[0060] In addition, the third manufacturing unit 230 may include a photoirradiation device that can irradiate the composite particles with light, thereby increasing the bonding force between the components of the composite particles and inducing stiffening of the composite particles.

[0061] The spark ejection device can produce metal nanoparticles from a metal electrode using spark discharge. "Spark discharge" refers to a high-frequency discharge method performed in kV-mA mode at normal pressure. Furthermore, the term "nano" in this application may refer to a size in nanometer (nm) units, for example, a size of 1 to 1000 nm, but is not limited thereto. Furthermore, the term "nanoparticle" in this application may refer to particles having an average diameter in nanometer (nm) units, for example, a particle having an average diameter of 1 to 1000 nm, but is not limited thereto.

[0062] The spark eruption device may include, for example, a discharge unit, an AC power supply unit, and an AC power supply control unit.

[0063] The discharge section is where spark discharge generates metal nanoparticles. The discharge section includes a pair of metal electrodes spaced apart by a predetermined distance. The pair of metal electrodes may be spaced apart to form a gap. For example, in the discharge section, the high temperature generated locally between the metal electrodes by spark discharge can generate metal nanoparticles.

[0064] The metal material constituting the metal electrode is not particularly limited as long as it is a conductive substance. For example, the metal electrode can include one or more selected from the group consisting of aluminum, antimony, tin, bismuth, carbon nanotubes, cerium, copper, cobalt, fullerene, POSS (Polyhedral OligomericSilsesquioxane), graphene, iron, magnesium, manganese, lead, gold, silver, nickel, silicon, titanium, yttrium, zinc and zirconium.

[0065] In addition, the metal nanoparticles generated from the metal electrodes can react with the oxygen gas passing between the metal electrodes to be denatured into oxides. For example, the types of metal nanoparticles generated between the metal electrodes can include one or more selected from the group consisting of aluminum, antimony, tin, bismuth, carbon nanotubes, cerium, copper, cobalt, fullerene, POSS (Polyhedral Oligomeric Silsesquioxane), graphene, iron, magnesium, manganese, lead, gold, silver, nickel, silicon, titanium, yttrium, zinc, zirconium, and their oxides.

[0066] The AC power supply unit can be the part that applies AC power or electricity to the metal electrode. The AC power supply unit can apply AC power to the metal electrode in the form of a pulse signal. Applying AC power as described above, unlike a DC power supply, eliminates the need for a separate frequency-variable circuit, offering the advantage of easily controlling the frequency.

[0067] The frequency and voltage of the AC power generated by the AC power supply unit can be controlled by the AC power supply control unit. The AC power supply control unit controls the frequency and voltage of the AC power applied to the metal electrode within a certain range, thereby supplying a constant AC current to the metal electrode.

[0068] In the AC power supply control unit, the frequency of the AC power supply can be controlled to be above 20 kHz, for example, above 30 kHz or above 40 kHz. The upper limit of the frequency is not particularly limited, for example, it can be below 1 MHz.

[0069] In addition, in the AC power control unit, the voltage of the AC power can be controlled within 2.2 to 5.0 kV, for example, 2.5 kV to 4.5 kV, 2.2 kV to 3.5 kV, 3.0 kV to 4.0 kV, or 3.5 kV to 5.0 kV, but is not limited thereto.

[0070] By controlling the frequency and voltage of the AC power supply applied to the metal electrode within the above range, even if spark discharge (rather than arc discharge) is used to produce inorganic particles, the diameter of the inorganic particles produced from the inorganic electrode can be kept in nanometers, while maximizing the amount of inorganic particles produced per hour.

[0071] Furthermore, the spark ignition device may include a DC power supply rather than an AC power supply.

[0072] In one example, the first to third supply parts 210 , 220 , and 230 (or the first to third manufacturing parts) may be connected to each other in series or in parallel.

[0073] For example, in the case of a serial connection, the sample aerosols produced in the first to third supply units 210, 220, 230 (or the first to third production units) can be applied to layer-by-layer compounding, and in the case of a parallel connection, the sample aerosols generated in each supply unit can be applied to random condensation.

[0074] The chamber system according to the present invention can produce sample aerosols by imitating aerosols generated in daily environments (such as aerosols generated during cooking) to specific environments (such as aerosols generated during welding) through the first to third production parts 210, 220, and 230.

[0075] In one example, the system may further include a pollutant supply unit 500 configured to supply gaseous pollutants to the organisms in the accommodation space.

[0076] The analysis unit 400 can analyze the effects of gaseous pollutants on the behavior, growth, and health of the organism based on changes in the organism's movements or images before and after the gaseous pollutants are supplied. Furthermore, the analysis unit 400 can analyze the effects of the sample aerosol and the gaseous pollutants on the behavior, growth, and health of the organism when both are supplied.

[0077] For example, gaseous pollutants may include one or more selected from the group consisting of carbon dioxide, formaldehyde, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, volatile organic compounds, aromatic hydrocarbons, methyl chloride, vinyl chloride, ammonia, ozone, naphthalene and radon, but are not limited thereto and may include various well-known gaseous pollutants.

[0078] In particular, carbon monoxide and nitrogen dioxide are suitable for studying atmospheric pollution in busy cities, while formaldehyde and volatile organic compounds are primarily used for indoor air quality studies. Radon can be used to study human exposure when released from building materials in the case of indoor air quality, or from soil in the case of atmospheric pollution.

[0079] Furthermore, the present invention may include a data storage unit that stores the monitoring results and analysis results as data. Through the data stored in the data storage unit, the user can understand the reaction of the organism exposed to the sample aerosol and take immediate follow-up actions.

[0080] In a specific example, the system may further include a bioaerosol supply unit configured to supply bioaerosol to the organisms in the accommodation space. Bioaerosol refers to air-rich viruses, bacteria, fungi, pollen, and the like.

[0081] In order to prevent the bioaerosol from being damaged, the bioaerosol can be supplied by using a vibrating grid atomization.

[0082] In another example, a sensor 600 may be included to measure the air quality of the storage space. Examples of sensor 600 include temperature sensors, humidity sensors, carbon dioxide sensors, dust sensors, and gas sensors. The results of sensor 600 can be transmitted to monitoring unit 300 in real time. Users can not only confirm changes in the movement or image of the organism, but also confirm changes in the air quality within the storage space in real time, helping them understand the correlation between the sample aerosol and air quality.

[0083] In a specific example, the chamber 100 includes a ventilation fan 700 that supplies external air to the accommodating space and exhausts the internal air of the accommodating space to the outside, and a control unit 800 that controls the operation of at least one of the ventilation fan 700, the supply unit 200, and the pollutant supply unit 500 based on the measurement results of the sensor 600.

[0084] The room system according to the present invention may further include a filter unit for purifying the internal air exhausted from the ventilation fan 700. The filter unit may include an air filter. The air filter may selectively remove specific gases. Since the performance of the air filter may deteriorate over time, an alarm unit may be provided to notify the user of the filter replacement period.

[0085] For example, the control unit 800 may include a first mode in which at least one of the ventilation fan 700, the supply unit 200, and the pollutant supply unit 500 is turned on (ON) when the measurement result of the sensor 600 exceeds a set reference value, and a second mode in which at least one of the ventilation fan 700, the supply unit 200, and the pollutant supply unit 500 is turned off (OFF) when the measurement result of the sensor 600 does not exceed the set reference value.

[0086] The control unit 800 can adjust the speed of the ventilation fan 700, the amount of the sample aerosol supplied from the supply unit 200, and the amount of the gaseous pollutants supplied from the pollutant supply unit 500 through the first and second modes. The first mode can increase or decrease the speed of the ventilation fan 700, increase or decrease the amount of the gaseous pollutants supplied, and increase or decrease the amount of the sample aerosol supplied based on the extent to which the measurement result of the sensor 600 exceeds a set reference value.

[0087] The control unit 800 may include a user interface so that the user can directly control the operation of the ventilation fan 700. In this way, the user can adjust the environment of the accommodation space according to his or her research purpose.

[0088] In one example, the chamber 100 may include a collecting portion 900 for collecting a sample candidate group including at least one of a sample aerosol and a gaseous pollutant supplied to the receiving space.

[0089] The collecting part 900 may be installed in at least one of the front section and the rear section of the chamber 100. In addition, the collecting part 900 may collect the sample candidate group in a gas state or a liquid state.

[0090] The collection unit 900 can use various known devices that can be used for collecting gas or liquid without limitation, and examples thereof include a collection substrate, a gas bag sampler for gas collection, and a liquid phase device for liquid collection.

[0091] The analysis unit 400 can perform physical, chemical, and biological analyses on the sample aerosol and gaseous pollutants using the sample candidate group collected from the collection unit.

[0092] The following briefly describes a chamber system capable of studying the effects of a sample aerosol on a living organism with reference to the accompanying drawings.

[0093] Figure 2 and Figure 3 is a diagram useful for understanding a chamber system capable of studying the effects of a sample aerosol on animals.

[0094] In one embodiment, the behavioral patterns of living animals (P, such as lizards, mice, etc.) exposed to a sample aerosol were analyzed using the chamber system according to the present invention.

[0095] refer to Figure 2 , prepare a chamber 100 for accommodating the living animal P, and supply the sample aerosol S to the accommodating space of the chamber 100 through the supply unit 200. And, as Figure 3 As shown, the accommodation space of the chamber 100 is 2D-converted by the monitoring unit 300 , and the starting position A, the travel path B, and the arrival position C of the living animal P are displayed on the converted 2D map.

[0096] Furthermore, the monitoring unit 300 displays not only the position of the animal P but also the time spent at a specific position on the 2D map. For example, positions where the animal spent a relatively long time are indicated by light colors, while positions where the animal spent a relatively short time are indicated by dark colors.

[0097] In addition, the analysis unit 400 stores the movement patterns of the living animal P and analyzes whether the sample aerosol S is toxic based on the stored movement pattern tendencies. For example, the analysis unit 400 analyzes that sample aerosols showing similar movement pattern tendencies show similar toxicity.

[0098] Figure 4 and Figure 5 is a diagram useful for understanding a chamber system capable of studying the effects of a sample aerosol on plants.

[0099] In other examples, the growth patterns of plants exposed to a sample aerosol were analyzed using a chamber system according to the present invention.

[0101] First, if Figure 4 As shown in (a) in FIG. 1 , as a control group, a chamber 100 containing plants was prepared, and no sample aerosol was supplied to the chamber 100 .

[0102] As the experimental group, Figure 4 As shown in (b) of FIG. 1 , a chamber 100 for accommodating plants is prepared, and a sample aerosol S is supplied to the accommodating space of the chamber 100 through the supply unit 200. Figure 5 As shown, the monitoring unit 300 monitors the changes in leaf length, leaf width, and leaf area over time.

In addition, the analysis unit 400 stores Figure 5 The results are obtained and the sample aerosol S is analyzed to see whether it is toxic based on the tendency of the stored graph.

[0104] For example, the analysis unit 400 analyzes that sample aerosols showing similar pattern tendencies show similar toxicity.
