Description

EXAMINATION SYSTEM AND EXAMINATION APPARATUS FOR EXHALATION

The following description relates to the examination system and the exhalation examination apparatus.

Respiratory diseases such as colds, sore throats, and pneumonia are diseases that are expressed by transmission of bacteria and viruses to the respiratory tract. After being expressed, the bacteria or virus proliferates in the nose or throat and leaks out through coughing and runny nose. Such bacteria or viruses multiply by themselves after infection in the human body and develop after an incubation period. Therefore, if the diagnosis fails at an early stage, it may cause great social confusion. In order to prevent highly contagious respiratory diseases, prompt and accurate diagnosis is essential. In addition, there is a need for a separate detection device to determine whether an asymptomatic person is identified during the incubation period or whether an infection is present when using indoor multi-use facilities. In vitro diagnostic tools that detect bacteria and viruses in real time are being developed in the field, but RT-PCR, a conventional in vitro diagnostic tool, has an accuracy of more than 95% in that it directly checks the genetic material, but the equipment required for this is expensive and requires several hours for diagnosis. It requires abnormalities and requires professionally trained inspectors. In addition, in the case of the immune antigen test, which is a rapid diagnostic kit, it takes 15 to 90 minutes to diagnose the result and can be used easily by the general public.

In order to quickly measure floating bacteria and viruses, equipment capable of detecting biological particles in the field in real time is being developed. However, in order to accurately determine the biological particles of the monitoring equipment being developed, it is necessary to minimize the influence of the external environment and to control non-living particles such as water vapor generated during respiration.

For example, there is an increasing need to apply these technologies to various detection/alarm devices in preparation for biochemical warfare, such as automatic chemical alarms or portable chemical agent detection equipment designated as defense materials according to the needs of national defense.
Chinese Patent Laid-Open Publication No. 109528184 (published on March 29, 2019) discloses a chamber including a component analysis device included in respiration.

The above-mentioned background art is possessed or acquired by the inventor in the process of derivation of the present invention, and cannot necessarily be said to be a known technology disclosed to the general public prior to the filing of the present invention.

1 is a diagram illustrating an examination system according to an exemplary embodiment.

Referring to FIG. 1 , the examination system 1 may directly and simply collect an organism or virus included in exhaled breath and detect it in real time to quickly and simply diagnose the sample. In addition, the examination system 1 may improve examination accuracy through pre-processing while excluding the influence of external air. For example, the examination system 1 may include a chamber assembly 11 , an exhalation examination apparatus 12 , a temperature-humidity control apparatus 13 , and a pump 14 .

The chamber assembly 11 may have a structure in which external air is blocked and air circulates inside the chamber assembly 11 . For example, it may be formed as a double wall and have a structure in which air circulates between the inside of the double wall and the wall of the double wall. The chamber assembly 11 may include an outer chamber 111 , an inner chamber 112 , and an opening/closing unit (not shown).

The outer chamber 111 may block the flow of air outside the chamber assembly 11 .

The inner chamber 112 may be disposed inside the outer chamber 111 . The inner chamber 112 may accommodate the examiner 2 and the exhalation examination device 12 . The inner chamber 112 may include a first circulation unit 1121 and a second circulation unit 1122 .

The first circulation unit 1121 may introduce air from the outside of the inner chamber. For example, the first circulation unit 1121 is located on the upper wall of the inner chamber 112 so that the upper air of the inner chamber 112 flows into the inner chamber 112 through the upper wall. can According to this structure, it is possible to reduce the problem that bacteria and viruses located relatively close to the ground are introduced into the inner chamber 112 . The first circulation unit 1121 may include a suction fan and a filtering unit.

The suction fan may introduce air from the outside of the inner chamber 112 .

The filtering unit may remove foreign substances from the air introduced through the suction fan. For example, the filtering unit may be located below the suction fan above the inner chamber 112 . According to the filtering unit, by removing foreign substances and fine particles, it is possible to reduce the problem that the examination result is distorted by the material flowing into the inner chamber 112 from the outside of the inner chamber 112 . The filtering unit may include a filter insertion groove formed in an upper wall of the inner chamber 112 , a filter inserted into the filter insertion groove, and a mounting lever capable of fixing or releasing the filter.

The second circulation unit 1122 may discharge air inside the inner chamber 112 . For example, the second circulation unit 1122 may be located below the sidewall of the inner chamber 112 so that the air inside the inner chamber 112 is discharged to the outside. According to such a structure, it is possible to discharge bacteria and viruses located relatively close to the ground to the outside of the inner chamber 112 and reduce the problem of re-introduction.

The opening/closing part may be opened and closed so that the examiner 2 can enter or exit from the outside of the chamber assembly 11 .

As described above, according to the sealing structure of the chamber assembly 11 , it is possible to fundamentally block the inflow of contaminants into the chamber assembly 11 from the outside. In addition, the contaminants in the inner chamber 112 in which the inspector 2 is located are discharged into the space between the inner chamber 112 and the outer chamber 111 , Contaminants from the air introduced into the inner chamber 112 from the space in between may be filtered. Therefore, it is possible to effectively reduce the influence of the surrounding environment again after taking the sample.

The exhalation examination apparatus 12 may analyze and diagnose the components of the exhalation of the examiner 2 breathing in the chamber assembly 11 .

The exhalation examination device 12 is installed in the inner chamber 112, and directly collects the exhalation of the examiner 2 breathing in the inner chamber 112 from the nostril or mouth, and analyzes the components of the collected exhalation, can be diagnosed For example, the exhalation examination device 12 may include a nozzle unit 121 (FIG. 3), an intake unit 122 (FIG. 3), an exhaust unit 123 (FIG. 3), and an analysis unit 124 (FIG. 3). have.

The nozzle unit 121 may be fixed in close contact with the face of the examiner 2 . For example, in the nozzle unit 121 , the exhaust unit 123 may be connected to a portion 22 corresponding to the nostril of the examiner 2 . For example, the nozzle unit 121 may be provided in a shape that covers the nose and does not cover the mouth so that air discharged from the examiner's mouth does not flow into the exhaust unit 123 . In other words, the nozzle unit 121 may be mounted on the nose of the examiner 2 . On the other hand, unless otherwise stated, the nozzle unit 121 may be provided in the form of a general mask covering the nose and mouth of the examiner 2 together.

The intake unit 122 may deliver the air sucked by the nasal pressure of the examiner 2 to the nasal cavity. For example, the intake unit 122 may remove non-living substances in the air while the air inside the chamber assembly 11 is sucked by the examiner's nasal pressure. Although the intake unit 122 is not shown in FIG. 1 , the diagnostic system 1 may include the intake unit 122 . For example, when the inhalation unit 122 is included in the diagnosis system 1 of FIG. 1 , the nozzle unit 121 may be connected to the portion 21 corresponding to the nostril of the examiner 2 . can Also, the nozzle unit 121 may prevent air discharged from the examiner's mouth from being introduced into the intake unit 122 . That is, since the air filtered by the filtering unit of the chamber assembly 11 may be pre-processed again by the intake unit 122 , the accuracy of exhalation diagnosis may be improved. The intake unit 122 may include an intake pipe 1221 ( FIG. 3 ), a dehumidifying module 1222 ( FIG. 3 ), a filter module 1223 ( FIG. 3 ), and an intake valve 1224 ( FIG. 3 ).

The intake pipe 1221 may pass through the nozzle unit 121 and be inserted into the nostril 21 of the examiner 2 . For example, the end of the intake pipe 1221 is provided with an insert made of an elastic and flexible material, so that it can be inserted into the nostril 21 of the examiner 2 having various sizes, and once inserted, the intake pipe ( 1221) It can be attached to the surrounding area so that air does not leak.

Along the intake pipe 1221 , air outside the intake unit 122 , that is, in the inner chamber 112 , may move toward the nozzle unit 121 .

The dehumidification module 1222 may be disposed on one side of the intake pipe 1221 and may remove moisture contained in the moving air. By removing water vapor in the air, it is possible to reduce false diagnosis of bacteria and viruses caused by this. For example, the dehumidifying module 1222 may include a dehumidifying agent and a case accommodating the dehumidifying agent so as to operate without a separate power supply. For example, the dehumidification module 1222 may be located downstream of the filter module 1223 based on the air inflow direction. According to this arrangement, the dehumidifying efficiency can be further improved while maintaining the clean level of the dehumidifying agent during use.

The filter module 1223 may be disposed on one side of the intake pipe 1221 and filter fine substances in the moving air. For example, the fine material may include non-living particles, and by filtering the fine material, it is possible to reduce false diagnosis of bacteria and viruses.

The intake valve 1224 may control opening and closing of the intake pipe 1221 . For example, the intake valve 1224 may be a check valve that allows air to flow in only one direction from the outside toward the nozzle unit 121 . For example, it may be opened only when the atmospheric pressure between the nozzle part 121 and the face part of the examiner 2 is lower than atmospheric pressure. According to this configuration, since the exhalation of the examiner 2 can be completely transmitted to the analysis unit 124 through the exhaust unit 123, the efficiency of diagnosis can be improved.

The exhaust unit 123 may deliver the air discharged by the examiner 2 through breathing to the analysis unit 124 . For example, the exhaust unit 123 may buffer the temperature change of the air while the examiner 2 exhaled air moves to the analysis unit 124 . Meanwhile, the exhaust unit 123 may be detachably attached to the analysis unit 124 . According to such a structure, an uncontaminated sample can be collected by replacing the exhaust unit 123 when the inspector changes. For example, the exhaust unit 123 may include an exhaust pipe 1231 ( FIG. 3 ), a heater module 1232 ( FIG. 3 ), and an exhaust valve 1234 ( FIG. 3 ).

The exhaust pipe 1231 may pass through the nozzle unit 121 and be inserted into the nostril 21 of the examiner 2 . For example, the end of the intake pipe 1221 is provided with an elastic and flexible insert, so that it can be inserted into the nostril 22 of the examiner 2 having various sizes, and once inserted, the exhaust pipe 1231 ) can be attached to the periphery so that air does not leak. The exhaust pipe 1231 and the intake pipe 1221 may be respectively inserted into a pair of different nostrils 21 and 22 of the examiner.

The heater module 1232 is disposed on one side of the exhaust pipe 1231, and performs a function of heating so that water vapor contained in the exhaled breath moving in the exhaust pipe 1231 is not condensed, thereby preventing bacteria and viruses caused by non-living particles. It can reduce the diagnosis. For example, the heater module 1232 may help to secure a constant and reliable diagnosis result by constantly maintaining the temperature of the air delivered to the analysis unit 124 . For example, the heater module 1232 may control the temperature of the heater module 1232 in conjunction with the temperature-humidity control device 13 . For example, the temperature of the heater module 1232 may be controlled to be the same as the temperature of the indoor air controlled by the temperature/humidity control device 13 .

The exhaust valve 1234 may control opening and closing of the exhaust pipe 1231 . For example, the exhaust valve 1234 may be a check valve that allows air to flow in only one direction from the nozzle unit 121 toward the analysis unit 124 . For example, it may be opened only when the atmospheric pressure between the nozzle part 121 and the face part of the examiner 2 is higher than atmospheric pressure. According to this configuration, it is possible to prevent the air introduced into the analysis unit 124 from being discharged to the examiner 2, and it is possible to prevent the problem that the exhalation of the existing examiner enters the next examiner.

The analysis unit 124 may analyze the air delivered from the exhaust unit 123 . For example, the analysis unit 124 may detect and diagnose viruses as well as organisms such as bacteria included in the exhalation of the examiner 2 .

The temperature-humidity control device 13 may control the temperature and humidity inside the chamber assembly 11 . The temperature-humidity control device 13 is configured to prevent condensation in the intake pipe 1221 and the exhaust pipe 1231 depending on the temperature of the intake pipe 1221 and the exhaust pipe 1231 , the body temperature of the examiner 2 , the outside air temperature, and the like. To prevent this from occurring, temperature and humidity can be controlled. For example, the temperature-humidity control device 13 controls the temperature so that the internal temperature of the internal chamber 112 is equal to the average temperature of the exhalation of the examiner 2 , and by sufficiently increasing the temperature of the exhaust pipe 1231 , the examiner When the exhalation of (2) is in contact with the exhaust pipe 1231, it is possible to prevent the water vapor from being condensed.

As shown in FIG. 3 , the pump 14 directs the air inside the chamber assembly 11 toward the nostril of the examiner 2 , or directs the flow of exhalation of the examiner 2 toward the analysis unit 124 , as shown in FIG. 3 . can do. For example, the pump 14 may be disposed on one side of the exhalation examination device 12 to help form an air flow in the direction of the arrow shown in FIG. 3 . For example, the pump 14 may (i) be disposed on one side of the exhaust unit 123 or the analysis unit 124 to induce air inside the exhaust pipe 1231 to flow toward the analysis unit 124 . and (ii) it may be disposed in the intake unit 122 to induce air inside the intake pipe 1221 to flow toward the nozzle unit.

Figure 2 is a view showing the principle of the exhalation screening device, Figure 5 is an experimental result comparing the biological particle detection performance of the conventional aerodynamic particle size distribution analyzer (Aerodynamic Particle Sizer, APS) and the exhalation screening device, Figure 6 is the exhalation It is a result showing the scattering signal information of the settler analyzed using the checkup device, Figure 7 is a result showing the fluorescence signal information of the settlement person analyzed using the exhalation checkup device.

Referring to FIG. 2 , the analysis unit 124 may detect induced fluorescence-based biological particles. The analysis unit 124 may determine whether biological particles are included in the exhalation by detecting a scattering signal and a fluorescence signal obtained by irradiating light of a specific wavelength (eg, ultraviolet rays) and classifying them as biological particles or normal particles. have. For example, the analysis unit 124 measures the intensity of scattered light generated from the light source unit 1241 irradiating light of a specific wavelength (eg, ultraviolet light) and the particles included in the exhalation by the light irradiated from the light source unit 1241 . and a scattering signal detector 1243 that measures the fluorescence intensity generated from particles included in exhalation by the light irradiated from the light source unit 1241 , and a fluorescence signal detector 1242 that measures the intensity of the fluorescence.

The analysis unit 124 may detect the number of particles included in the exhalation according to whether a signal greater than or equal to a specific value is detected by the fluorescence signal detection unit 1242 or the scattering signal detection unit 1243 . In FIG. 3 , (a) is a fluorescence signal detected by the fluorescence signal detector 1242 , and (b) is a scattering signal detected by the scattering signal detector 1243 . At this time, when a signal of a specific value or more is simultaneously detected by the fluorescence signal detection unit 1242 and the scattering signal detection unit 1243, it is determined as a biological particle. have. By comparing the normal particle number and the biological particle number measured in this way with the scattering data and fluorescence data of a normal person as shown in FIGS. 7 and 8 , it is possible to quickly diagnose the possibility of bacterial infection of the examiner 2 .

The analysis unit 124 is capable of measuring not only biological particles but also small particles such as viruses. Referring to FIG. 5 , as compared with a conventional aerodynamic particle size distribution analyzer, the analysis unit 124 shows a result capable of measuring even particles having a smaller particle size. For example, the analysis unit 124 may measure particles of 0.5 μm or less.

Figure 3 is a view showing an exhalation check apparatus according to an embodiment.

FIG. 3 shows an examination system including only the exhalation examination device 12 without the chamber assembly 11 . When the exhalation examination device 12 is used alone, it is not necessary to provide the chamber assembly 11 , so it is possible to quickly and simply diagnose the exhalation of the examiner 2 . At this time, since the air is pre-treated by the intake unit 122, the influence of the outside air on the diagnosis result can be reduced.

Figure 4 shows the examination system including only one chamber 112 and the exhalation examination device 12, without the external chamber 111. When the chamber 112 is used alone, the temperature and humidity control device 12 may be disposed at the lower end of the first circulation unit 1121 . According to such a structure, temperature and humidity can be adjusted while air is introduced into the chamber 112 from the outside, and air having an appropriate temperature and humidity can circulate through the chamber 112 .
