Description

  The present invention relates to, for example, a notification system and a notification method for notifying of the degree of risk of infection by a pathogen such as a virus contained in the air.

  A pathogen such as a virus contained in the air is collected, and the concentration of the pathogen contained in the air is measured by, for example, fluorescence spectroscopy, surface enhanced Raman scattering spectroscopy, or the like.

  Conventionally, optical measurement techniques such as fluorescence spectroscopy and surface-enhanced Raman scattering have been used for various applications. For example, techniques for measuring the concentration of pathogens such as bacteria and fungi in air using fluorescence spectroscopy Are disclosed (see, for example, Patent Document 1). The use of fluorescence spectroscopy makes the concentration of pathogens in the air unnecessary for consumables such as reagents, test strips and enzymes, and also the storage safety of these consumables and the problem of disposal after use The quantitative measurement can be performed without the problems such as the complicated operation causing the error and the interference by other components.

  As a surface-enhanced Raman spectroscopy measurement method, a surface-enhanced Raman scattering consisting of a nanometer-sized structure formed of a noble metal, such as a Raman-active substance such as an antibody that specifically captures a virus or the like forming a stoichiometric relationship with an analyte Discloses a technique for measuring surface enhanced Raman scattering generated by an enhanced electric field generated by localized surface plasmons generated on the nanostructures by coexisting on a substrate that generates . According to the present technology, surface-enhanced Raman scattering can be excited with high efficiency using the wavelength of light in the near infrared region, and is analyzed by Raman spectroscopy in the near infrared region by exciting with light in the near infrared region This makes it possible to improve the specificity and selectivity in the detection of the analyte by eliminating the influence of light absorption and fluorescence of contaminants in the matrix containing the analyte.

  Hereinafter, embodiments of the present invention will be described in detail.

Embodiment 1
FIG. 1 is a block diagram showing a schematic configuration of informing apparatus 100 according to Embodiment 1 of the present invention.

  The notification device 100 includes a virus concentration calculating unit 101 that calculates a virus concentration in a predetermined area, a time calculating unit 102 that calculates a time when a user exists in the predetermined area (for example, a user's stay time), and the virus concentration The virus exposure calculation means 103 for calculating the virus exposure of the user from the output of the calculation means 101 and the output of the time calculation means, the storage means 104 for storing the threshold of the virus exposure, and the virus exposure calculation A control unit 105 that determines that the output of the means 103 is equal to or more than the threshold stored in the storage means (for example, indicates a value greater than the threshold), and the user according to the output of the control unit And notification means 106 for notifying.

  The notification unit 106 may notify the user, for example, when the output of the virus exposure amount calculation unit 103 is equal to or greater than a threshold as a result of the determination by the control unit.

  Alternatively, the notification unit 106 may notify the user that the output of the virus exposure amount calculation unit 103 is smaller than a threshold as a result of determination by the control unit, for example.

  The virus concentration calculation means 101 comprises a virus detection means 107 for detecting a virus in a predetermined area, and an input means 108 for inputting the size of the predetermined area. The size of the predetermined area may be input by the user before use by the input unit 108, or may be set in advance.

  The virus detection unit 107 detects a virus and measures the amount of virus in a predetermined area.

  The virus concentration calculation means 101 can calculate the virus concentration of the predetermined area from the output of the virus detection means 107 and the output of the input means 108 (for example, the size of the predetermined area inputted by the input means 108).

  Here, in the present embodiment, as long as the virus detection unit 107 is a technology capable of specifically detecting a virus, known technology can be used without particular limitation. For example, a technique of detecting viruses in the air using surface enhanced Raman scattering, and a technique of measuring the concentration of pathogens such as bacteria and fungi in the air using fluorescence spectroscopy can be used.

  Here, it is desirable that the predetermined area is indoor or indoor. The predetermined area may be an outdoor predetermined place or the like.

  When a virus is present in the air of a predetermined area, the amount of virus taken by the user changes depending on the length of stay time of the user in the predetermined area.

  The time calculation means 102 includes a user detection means 109 for detecting a user in a predetermined area (for example, detecting that a user is present in the predetermined area).

  When the user detection unit 109 detects that the user is staying in the predetermined area, the time calculation unit 102 determines, based on the output of the user detection unit 109, the presence time of the user in the predetermined area (for example, the stay time) Measure).

  Here, in the present embodiment, the time calculation means 102 uses, for example, a clock function that outputs time information and a timer that measures the time when the user stayed in a predetermined area in conjunction with the detection of the user detection means 109. ing. Also, the user detection unit 109 uses, for example, an infrared sensor that detects infrared radiation emitted by the user.

  By doing this, based on the output of the first infrared sensor from the initial state of the notification device 100, the timer starts measuring the time during which the user stays in the predetermined area, and the infrared sensor does not detect the user in the predetermined area When outputting that, the timer ends the measurement of the time when the user stays in the predetermined area.

  By doing this, it is possible to measure the staying time of the user.

  Furthermore, the time calculation means 102 can prepare for the next measurement by returning to the initial state when the measurement of the time when the user stays in the predetermined area is finished.

  Here, the user detection unit 109 can be used as long as it can detect the presence of a user. For example, various sensors such as an ultrasonic sensor, a laser light reflection sensor, a photoelectric tube, and a capacitance sensor can be used.

  Preferably, the user detected by the user detection means is a person. The user may be an animal other than a human.

  The notification device 100 according to the first embodiment includes a virus exposure amount calculation unit 103, a storage unit 104, a control unit 105, and a notification unit 106.

  The virus exposure amount calculation means 103 calculates the virus exposure amount of the user by multiplying the output of the virus concentration calculation means 101 and the output of the time calculation means 102 by the known amount of air sucked by the user per unit time. At this time, the control unit 105 determines whether the calculated virus exposure amount is equal to or more than the threshold value stored in the storage unit 104 based on the user's virus exposure threshold value stored in advance in the storage unit 104. to decide. At this time, if the calculated virus exposure amount is equal to or more than the threshold value, the control unit 105 transmits a signal equal to or more than the threshold value to the notifying unit 106 as a signal, and the notifying unit 106 notifies the user.

  This can indicate that there is a high risk of infection with the virus.

  Here, the amount of air sucked by the user per unit time, which is a value necessary for calculation in the virus exposure amount calculation means, is 6 L per minute on average at rest, and the user's virus stored in advance in the storage means The exposure threshold may be set on the basis of the infectivity titer of a virus that is at risk of infecting about 50% of people.

  Here, in the present embodiment, the notification unit 106 is configured of an LED display, and blinks the LED display to notify the user of the risk of infection. Here, the notification means 106 can be used if it is a technology that can notify the user of the danger. For example, an alarm generator or the like can be used which notifies of a danger by the sound of a blinking fluorescent lamp or a buzzer.

  FIG. 2 is a flowchart of a notification method according to Embodiment 1 of the present invention.

  That is, the notification method according to the first embodiment includes a virus concentration calculating step of calculating the virus concentration in a predetermined region, a time calculating step of calculating a time when a user exists in the predetermined region, and the virus concentration calculating step. The calculation result of the virus exposure amount calculation step for calculating the virus exposure amount of the user from the calculation result of the time calculation step and the calculation result in the time calculation step and the calculation result in the virus And a notification step of notifying the user according to the determination result of the determination step.

  This can inform the user that there is a high risk of being infected with a virus.

  In the determination step, when the calculation result in the virus exposure amount calculation step is equal to or more than a preset threshold value, the user may be notified in the notification step.

  Alternatively, when it is determined in the determination step that the calculation result in the virus exposure amount calculation step is smaller than a preset threshold value, the notification step indicates that the calculation result in the virus exposure amount calculation step is smaller than the threshold value. May be informed to the user.

  As shown in FIG. 2, the notification method may further include a virus detection step of detecting a virus in a predetermined area, and an input step in which the size of the predetermined area is input.

  At this time, the virus concentration calculation step may calculate the virus concentration of the predetermined region from the detection result of the virus detection step and the input result of the input step.

  Note that, as shown in FIG. 2, the notification method may further include a user detection step of detecting a user in a predetermined area.

  At this time, the time calculation process may calculate the presence time of the user in the predetermined area based on the detection result of the user detection process.

  Note that, as shown in FIG. 2, the notification method may further include a storage step of storing the threshold value of the virus exposure amount in a storage means of the notification device or the like.

In a more specific example, the virus detection unit 107 detects the amount of virus in a predetermined area, and the virus concentration is calculated from the result and the size of the predetermined area input in advance. The user detection means detects the user who is in the predetermined area, and the time measurement means linked to the user detection calculates the stay time of the user. The exposure amount of the virus is calculated from the calculated virus concentration and the staying time, and it is judged whether or not the calculated value is equal to or more than the threshold of the virus exposure amount for the user stored in advance. If the threshold value is equal to or higher than the threshold value, the notification unit 106 notifies the user (for example, the LED blinks to notify).

  In addition, it becomes possible to monitor the risk to the virus infection continuously if the calculation of the virus exposure amount is carried out at a certain constant time and it is determined whether or not the threshold value is exceeded each time.

  Alternatively, if it is determined in the determination step that the calculation result in the virus exposure amount calculation step is smaller than a preset threshold value, the process may return to the virus exposure amount calculation step and repeat again.
