[Figure 7] FIG. 4 is a block diagram showing the configuration of a portable breathalyzer according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. However, the components described in the embodiment are merely examples and are not intended to limit the scope of the present invention.

[0013] (First embodiment) FIG. 1 is a block diagram showing the configuration of a portable breathalyzer according to a first embodiment of the present invention. 1, the portable breathalyzer 1 has a detector body 10 and a head unit 20 that is detachably attached to the detector body 10. The detector body 10 has a second control unit 11, a second output unit 12, an operation unit 13, and a terminal 14. The head unit 20 has a first control unit 21, a first output unit 22, an alcohol sensor 23, and a terminal 24. When the head unit 20 is attached to the detector body 10, the terminal 14 and the terminal 24 are connected.

[0014] The first output unit 22 outputs information. The alcohol sensor 23 detects the alcohol concentration in the breath of the subject. For example, a semiconductor gas sensor can be used as the alcohol sensor 23. The expiration date of the semiconductor gas sensor is, for example, about one year in terms of the number of days of use and about 1000 times in terms of the number of uses. The first output unit 22 may include a terminal 24. The first control unit 21 counts the number of times or the number of days of use of the alcohol sensor 23. The number of days of use is the number of days that have passed since the start date of use of the alcohol sensor 23. In response to a request to confirm the usage level of the alcohol sensor 23, the first control unit 21 causes the first output unit 22 to output sensor management information including the count value of the number of times or the number of days of use and identification information of the head unit 20.

[0015] According to the above configuration, the number of days or number of times the alcohol sensor 23 has been used can be managed for each head unit, based on the sensor management information output from the first output unit 22. For example, when the head unit 20 is replaced with another head unit 20, the sensor management information of the other head unit 20 can be identified based on the identification information of the head unit. In addition, since the head unit 20 is replaceable, the operating costs of the portable breathalyzer 1 can be reduced.

[0016] The first output unit 22 may have a first display unit that displays a count value of the number of uses or the number of days of use. This allows the user to judge the life of the alcohol sensor 23 from the count value displayed on the first display unit. Furthermore, the first control unit 21 may cause the first display unit to display a message prompting the user to replace the head unit 20 when the count value of the number of uses or the number of days of use reaches a predetermined value. This allows the user to recognize the timing of replacing the head unit based on the message displayed on the first display unit.

[0017] Furthermore, the first output unit 22 may have a first communication unit capable of communicating with an external device, and the sensor management information may be transmitted from the first communication unit to the external device. This allows the sensor management information from the head unit 20 to be managed by an external device (for example, a mobile terminal or a server) even when the head unit 20 is detached from the detector body 10. The operation unit 13 allows information to be input, and includes operation buttons and the like for operating the portable breathalyzer 1. With the head unit 20 attached to the detector body 10, the first control unit 21 can receive a request to confirm the usage level of the alcohol sensor 23 via the operation unit 13. The first control unit 21 can also receive a request to confirm the usage level of the alcohol sensor 23 from an external device via the first communication unit.

[0018] The second output unit 12 outputs information. The second control unit 11 receives sensor management information from the first control unit 21, and outputs the sensor management information from the second output unit 12. Based on the sensor management information output from the second output unit 22, the number of days of use and the number of times of use of the alcohol sensor 23 can be managed for each head unit. The second output unit 12 may have a second display unit that displays a count value of the number of uses or the number of days of use. This allows the user to judge the life of the alcohol sensor 23 from the count value displayed on the second display unit. In addition, the second control unit 11 may cause the second display unit to display a message prompting the user to replace the head unit 20 when the count value of the number of uses or the number of days of use reaches a predetermined value. This allows the user to recognize the timing of replacing the head unit based on the message displayed on the second display unit.

[0019] The second output unit 12 may also have a second communication unit capable of communicating with an external device, and the sensor management information may be transmitted from the second communication unit to the external device. This allows the sensor management information from the detector main body 10 to be managed by an external device (for example, a mobile terminal or a server). The detector main body 10 may have a temperature sensor that detects the body surface temperature. In this case, the second control unit 11 may cause the second output unit 12 to output measurement data including the subject's identification information, the alcohol concentration detection value of the subject detected by the alcohol sensor 23, and the body surface temperature detection value of the subject detected by the temperature sensor. This makes it possible to collectively manage the measurement data of the subject in an external device (e.g., a mobile terminal or a server). The subject's identification information can be inputted by the operation unit 13.

[0020] Next, an information management system using the portable breathalyzer 1 will be described. Fig. 2 is a block diagram showing an example of an information management system. Referring to Fig. 2, the information management system includes the above-mentioned portable breathalyzer 1, a mobile terminal 3, and a server 40. The mobile terminal 3 operates in cooperation with the portable breathalyzer 1. The mobile terminal 3 is, for example, a smartphone or a tablet terminal. The mobile terminal 3 has a control unit 31, communication units 32 and 33, a memory unit 34, a display unit 35, an operation unit 36, and a camera unit 37. The control unit 31 is composed of a computer such as a CPU (Central Processing Unit). The memory unit 34 stores programs and data. The operation unit 36 ​​allows information to be input, and includes operation buttons for operating the mobile terminal 3.

[0021] The communication unit 32 is capable of communicating with the portable breathalyzer 1. For example, the communication unit 32 performs short-range wireless communication such as Bluetooth with the second output unit 12 shown in FIG. 1. The communication unit 33 is capable of communicating with the server 4. For example, the portable terminal 3 and the server 4 are placed on a network such as the Internet, and the communication unit 33 can access the server 4 via the network. The camera unit 37 is an example of an acquisition unit that acquires biological information of the subject.

[0022] The control unit 31 acquires sensor management information including a count value of the number of times the alcohol sensor has been used or the number of days it has been used and identification information of the head unit 20 from the portable breathalyzer 1 in response to an input operation of the operation unit 36. The control unit 31 transmits the sensor management information to the server 4, and the server 4 stores the sensor management information. The control unit 31 also acquires measurement data of the subject from the portable breathalyzer 1, and stores the measurement data in the server 4 in association with the biological information of the subject acquired by the camera unit 37. Biometric information is information specific to a living organism, such as face or fingerprint. In this embodiment, information indicating facial features extracted from image data of the subject's face captured by the camera unit 37 is used as the biometric information. Image data for authentication of the subject's face is stored in advance in the memory unit 34. The control unit 31 compares the image data of the subject's face captured by the camera unit 37 with the image data for authentication stored in the memory unit 34, and starts measurement of the portable breathalyzer 1 when the facial features match.

[0023] According to the above information management system, the sensor management information of the multiple head units 20 can be collectively managed on the server 4. For example, in an operation mode in which alcohol checks are performed by having multiple subjects each carry a portable breathalyzer 1, the sensor management information of the head unit 20 of each portable breathalyzer 1 can be collectively managed on the server 4. Also, in an operation mode in which multiple head units 20 are used for one portable breathalyzer 1, the sensor management information of each head unit 20 can be collectively managed on the server 4. In either mode, the measurement data of the subjects can be collectively managed on the server 4. In addition, authentication using biometric information (such as facial recognition) can also be used to prevent impersonation.

[0024] The above-mentioned processes performed by the control unit 31 (for example, a series of processes related to sensor management information, measurement data, and biological information) may be realized by a computer executing a program in which the process contents are described as procedures. The program may be provided to the mobile terminal 3 using a portable recording medium such as a Universal Serial Bus (USB) memory. The program may also be provided to the mobile terminal 3 via a network such as the Internet.

[0025] Second embodiment Figures 3, 4 and 5 are schematic diagrams showing the external appearance of a portable breathalyzer according to a second embodiment of the present invention. Figure 3 is a front view. Figure 4(a) is a perspective view showing the front and right side. Figure 4(b) is a perspective view showing the back and left side. Figure 5 is a perspective view showing the state in which the head unit is removed from the detector main body. 3 to 5, the portable breathalyzer 2 has a detector body 40 and a head unit 50 that is detachably attached to the detector body 40. The detector body 40 has a display unit 41, a power button 42, an alcohol measurement button 43, a temperature measurement button 44, lock buttons 45a and 45b, an indicator 46, a temperature sensor 47, a charging port 48, and a terminal 49. The head unit 50 has a blow port 51, a blow hole 52, a lock button 53, and a terminal 54.

[0026] The display unit 41 displays various information related to the operation of the portable breathalyzer 2. The power button 42 is a button for turning the power on / off. The alcohol measurement button 43 is a button for starting an alcohol measurement. The temperature sensor 47 detects the body surface temperature of the subject. The temperature measurement button 44 is a button for starting measurement of the body surface temperature. The indicator 46 displays the operation mode of the portable breathalyzer 2. For example, the indicator 46 can display various operation modes such as an alcohol measurement mode and a temperature measurement mode. The charging port 48 is for charging a secondary battery (e.g., a lithium battery) built into the portable breathalyzer 2. For example, a USB Type C connector can be used as the charging port 48.

[0027] The lock buttons 45a and 45b are buttons for fixing the head unit 50 to the detector body 40, and the head unit 50 can be removed from the detector body 40 by pressing both of them at the same time. A terminal 49 is provided on the portion of the detector body 40 where the head unit 50 is attached. With the head unit 50 attached to the detector body 40, the terminal 49 of the detector body 40 and the terminal 54 of the head unit 50 are connected. With the terminal 49 and the terminal 54 connected, asynchronous serial communication, for example, UART (Universal Asynchronous Receiver Transmitter) communication, is performed between the detector body 40 and the head unit 50. For example, a USB Type C connector can be used as the terminals 49 and 54.

[0028] The blowing port 51 and the blowing port 52 are for performing an alcohol measurement. In this embodiment, both blowing and straw-type measurements are possible. In the blowing type measurement, the blowing port 51 and the blowing port 52 are used. The subject blows into the blowing port 51 to detect the alcohol concentration in the breath. On the other hand, in the straw-type measurement, a straw built into the head unit 50 is used. Fig. 6 is a schematic diagram showing the straw portion. By pressing the lock button 53, the lid 56 of the head unit 50 opens, and the straw 55 built into the head unit 50 appears. The subject injects breath into the straw 55, and the alcohol concentration in the breath is detected. The straw 55 is replaceable.

[0029] Next, the configuration relating to the control of the portable breathalyzer 2 will be specifically described. FIG. 7 is a block diagram showing a configuration related to the control of the portable breathalyzer 2. As shown in FIG. 7, the head unit 50 has a control unit 60, a memory unit 61, an alcohol sensor 62, a microphone 63, a flow path 64, and a timer 65 in addition to the configuration shown in FIG. 3 to FIG. 6. The blowing port 51 and the blowing port 52 are connected by a flow path 64, and the alcohol sensor 62 and the microphone 63 are provided in this flow path 64. Although not shown, the straw 55 shown in FIG. 6 also communicates with the flow path 64. The alcohol sensor 62 is the same as the alcohol sensor 23 described in the first embodiment. The microphone 63 detects the sound of blowing into the mouth 51 or the straw 55 (the sound generated when air flows through the flow path 64).

[0030] The storage unit 61 is made of a semiconductor memory or the like (preferably a non-volatile memory) and is capable of holding various information related to the operation of the head unit 50. For example, identification information of the head unit 50, information related to the number of times the alcohol sensor 62 has been used, the number of days of use, and the expiration date, and display data including measurement data are stored in the storage unit 61. The control unit 60 is made of an MCU (Micro Controller Unit) and controls the operation of each part of the head unit 50. The control unit 60 corresponds to the first control unit 21 described in the first embodiment. The timer 65 is an example of a time measurement means that counts the number of days of use of the alcohol sensor 62.

[0031] The detector main body 40 has a control unit 70, a storage unit 71, a communication unit 72, a secondary battery 73, and a speaker 74 in addition to the configuration shown in FIG. 3 to FIG. 6. The control unit 70 is made of an MCU and controls the operation of each unit of the portable breathalyzer 2. The control unit 70 corresponds to the second control unit 11 described in the first embodiment. The storage unit 71 is made of a semiconductor memory or the like and can hold various information related to the operation of the portable breathalyzer 2. For example, the identification information of the detector main body 40, sensor management information, and display data including measurement data are stored in the storage unit 71. The secondary battery 73 can be charged through the charging port 48. The speaker 74 can output various patterns of sound signals indicating, for example, operation modes and warnings. The communication unit 72 performs short-distance wireless communication such as Bluetooth with an external device (a mobile terminal such as a smartphone).

[0032] The subject can take an alcohol test and a temperature measurement using the portable breathalyzer 2. The operations of the alcohol test and the temperature measurement will be described below.

[0033] <Alcohol check> When the alcohol measurement button 43 is pressed, the operation mode transitions to the alcohol measurement mode. In the alcohol measurement mode, the control unit 70 sends a command signal to the control unit 60 to activate the alcohol sensor 62, and the control unit 60 activates the alcohol sensor 62 according to the command signal. The control unit 70 causes the speaker 74 to output an acoustic signal indicating the alcohol measurement mode, and then displays information indicating that measurement preparation is complete on the display unit 41. If the user blows into the blow hole 51 within a predetermined time after the display indicating that measurement preparation is complete, the alcohol sensor 62 detects the alcohol concentration contained in the breath. The control unit 60 sends the alcohol concentration detection value detected by the alcohol sensor 62 to the control unit 70. The control unit 70 displays the alcohol concentration detection value on the display unit 41 and stores it in the memory unit 71.

[0034] The control unit 60 determines whether or not breath has been blown into the blowing port 51 continuously for a predetermined time based on the output of the microphone 63. If breath has not been blown into the blowing port 51 continuously for the predetermined time, the control unit 60 sends a command signal indicating an error to the control unit 70, and the control unit 70 displays information indicating the error on the display unit 41 in accordance with the command signal. In addition, the control unit 70 can display information indicating an abnormality on the display unit 41 when the alcohol concentration detection value is higher than the threshold value, and can display information indicating normality on the display unit 41 when the alcohol concentration detection value is equal to or lower than the threshold value. Furthermore, the control unit 70 can cause the communication unit 72 to transmit the alcohol concentration detection value detected by the alcohol sensor 62 to an external device.

[0035] <Temperature check> When the temperature measurement button 44 is pressed, the operation mode transitions to the temperature measurement mode. In the temperature measurement mode, the control unit 70 activates the temperature sensor 47, causes the speaker 74 to output an acoustic signal indicating the temperature measurement mode, and displays information indicating that measurement preparation is complete on the display unit 41. When the temperature sensor 47 is brought close to the subject's forehead or the like, the temperature sensor 47 detects the body surface temperature. The control unit 70 displays the body surface temperature detection value detected by the temperature sensor 47 on the display unit 41 and stores it in the memory unit 71. When the detected body surface temperature value is lower than the first threshold, the control unit 70 displays information indicating that the body temperature is low on the display unit 41, and when the detected body surface temperature value is higher than the second threshold (> the first threshold), the control unit 70 displays information indicating that the body temperature is high on the display unit 41. The first threshold and the second threshold can be set appropriately. The control unit 70 can cause the communication unit 72 to transmit the body surface temperature detected by the temperature sensor 47 to an external device.

[0036] Next, management of the expiration date of the alcohol sensor 62 will be described. When the alcohol sensor 62 is activated for the first time, the control unit 60 obtains the activation date and time using the timer 65, and stores the date of start of use in the memory unit 61. Depending on whether the date of start of use is stored in the memory unit 61, it is possible to determine whether the alcohol sensor 62 has been activated for the first time. The control unit 60 counts the number of days that have passed since the start of use of the alcohol sensor 62, using the timer 65. The control unit 60 stores the count value in the memory unit 61 as the number of days of use. Furthermore, when the alcohol measurement button 43 is pressed to transition to the alcohol measurement mode and the alcohol sensor 62 detects an alcohol concentration in the subject's breath, the control unit 60 determines that the alcohol sensor 62 has been used once. The control unit 60 stores the current number of times the alcohol sensor 62 has been used in the memory unit 61. The control unit 60 increments the number of times it has been used by one each time the alcohol measurement button 43 is pressed and the alcohol sensor 62 detects an alcohol concentration.

[0037] In response to a request to confirm the usage level of the alcohol sensor, the control unit 60 generates sensor management information including the number of days of use, the number of times of use, and the identification information of the head unit 50 stored in the memory unit 61. For example, when the control unit 70 detects that a specific button has been pressed, it sends a command signal indicating a request to confirm the usage level to the control unit 60. The control unit 60 creates sensor management information at the timing of receiving the command signal, and sends the sensor management information to the control unit 70. The control unit 70 displays the sensor management information received from the control unit 60 on the display unit 41. The specific button may be a dedicated button, or may be used in combination with the power button 42 or the alcohol measurement button 43. The control unit 70 can also receive a usage level confirmation request from an external device via the communication unit 72 and send a command signal to the control unit 60. In this case, the control unit 70 transmits the sensor management information received from the control unit 60 from the communication unit 72 to the external device that has sent the usage level confirmation request.

[0038] When the head unit 50 is removed from the detector body 40, power supply from the detector body 40 to the head unit 50 is stopped, but the stored information is maintained in the memory unit 61. For example, information on the number of days and number of times the alcohol sensor 62 has been used immediately before power supply was stopped, and identification information of the head unit 50 are still maintained in the memory unit 61. It is also possible to connect the terminal 54 of the removed head unit 50 to an external device and retrieve the information stored in the memory unit 61. When the removed head unit 50 is attached to the detector body 40 again, power supply from the detector body 40 to the head unit 50 is resumed. After power supply is resumed, the control unit 60 in the head unit 50 starts counting from the number of days of use when power supply was stopped, which is stored in the memory unit 61. This makes it possible to accurately count the number of days of use even after power supply is resumed. Counting the number of times of use is also resumed from the number of times of use when power supply was stopped, which is stored in the memory unit 61. This makes it possible to accurately count the number of times of use.

[0039] In the portable breathalyzer 2 of this embodiment, as in the first embodiment, the number of days and number of times the alcohol sensor 62 has been used can be managed for each head unit, and the operating costs can be reduced. Furthermore, similarly to the first embodiment, the portable breathalyzer 2 of this embodiment can also perform information management in cooperation with a portable terminal such as a smartphone.

[0040] For example, in the information management system shown in Fig. 2, a portable breathalyzer 2 is used instead of the portable breathalyzer 1. Each of a number of subjects is provided with the portable breathalyzer 2 and the portable terminal 3 to perform an alcohol check and temperature measurement. In this case, the results of the alcohol check and temperature measurement for each subject can be collectively managed on the cloud server, and the expiration date of the alcohol sensor of each portable breathalyzer 2 can be collectively managed for each head part.
