[0013] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the present disclosure, there was a technology that presented the necessity of infection control in a space, such as Patent Document 1. Incidentally, in a hospital, an examination room and a waiting room may be adjacent to each other. In this case, when an airflow is generated from the waiting room toward the examination room, an airflow is generated in the examination room from the waiting room toward the doctor, so that the doctor who examines in the examination room may be infected with a disease of a patient or a sick animal waiting in the waiting room. In addition, in a hospital, a waiting room and a reception room may be adjacent to each other. Similarly, in this case, when an airflow is generated from the waiting room toward the reception room, a medical worker in the reception room may be infected with a disease of a patient or a sick animal waiting in the waiting room. In this way, in a hospital, there is a risk that a medical worker may be infected with a disease depending on the airflow situation in an adjacent space, so that there has been a demand for medical workers in the hospital to grasp the airflow situation in the space where they are engaged in medical care. This is because if medical staff at a hospital can understand the airflow conditions in the space where they are practicing medicine, they can practice medicine with peace of mind, and when infection control measures are necessary, they can understand that. However, the inventors discovered a problem in that Patent Document 1 does not take into account the airflow conditions in adjacent spaces when presenting the need for infection control measures, and therefore cannot meet the above demand, and have come to constitute the subject of the present disclosure in order to solve this problem. Therefore, the present disclosure provides an information output system for hospitals, an information output method for hospitals, and a program that enable medical staff at hospitals to provide medical care with peace of mind and to understand that infection control measures are necessary when infection control measures are necessary.

[0014] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially the same configurations may be omitted. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

The information output system 1000 is a system for a hospital H. The hospital H in this embodiment is an institution that provides medical care to a patient P, and does not matter if it is a facility that accommodates a patient P. In other words, the hospital H in this embodiment may be an institution that provides medical care to outpatients, or an institution that provides medical care to outpatients and inpatients.

The third terminal device 8 is connected to the communication device 6, and communicates with the server device 7 connected to the network NW via the communication device 6. The information output system 1000 may include a plurality of third terminal devices 8.

[0028] The information output system 1000 includes a differential pressure sensor 9 that detects the difference between the air pressure in the examination room ER and the air pressure in the waiting room WR (hereinafter, referred to as "differential pressure"). The information output system 1000 of this embodiment includes a plurality of differential pressure sensors 9. In this embodiment, a differential pressure sensor 9 is provided for each examination room ER. The differential pressure sensor 9 includes a first air pressure sensor 91 and a second air pressure sensor 92. The first air pressure sensor 91 is disposed in the examination room ER and detects the air pressure in the examination room ER. The first air pressure sensor 91 is disposed around the exhaust port EP of the door DR. The second air pressure sensor 92 is disposed in the waiting room WR and detects the air pressure in the waiting room WR. The second air pressure sensor 92 is disposed around the exhaust port EP of the door DR leading to and from the examination room ER where the paired first air pressure sensor 91 is disposed. The detection method of the first air pressure sensor 91 and the second air pressure sensor 92 is not limited to a specific method, and may be, for example, a piezoresistance method, a film formation method, or a capacitance method.

[0029] The differential pressure sensor 9 is connected to the communication device 6 for communication, and communicates with the server device 7 connected to the network NW via the communication device 6. The differential pressure sensor 9 detects the differential pressure at a predetermined period, and transmits the first upload data D1 to the server device 7 each time the sensor detects the differential pressure. The first upload data D1 records a sensor ID (Identification) that uniquely identifies the differential pressure sensor 9, and the differential pressure that is the detection result. The differential pressure sensor 9 in this embodiment detects the differential pressure with respect to the air pressure in the examination room ER. Therefore, if the differential pressure detected by the differential pressure sensor 9 is a positive value, the air pressure in the examination room ER is higher than the air pressure in the waiting room WR, and if the differential pressure detected by the differential pressure sensor 9 is a negative value, the air pressure in the examination room ER is lower than the air pressure in the waiting room WR. The value of the differential pressure is expressed in hectopascals.

The ventilation device 10 may also include a filter that collects dust, fine particles, virus droplets, aerosols, etc.

[0031] The ventilation device 10 is communicatively connected to the communication device 6 and communicates with the server device 7 via the communication device 6. The ventilation device 10 of this embodiment periodically transmits second upload data D2 to the server device 7. The second upload data D2 records a device ID that uniquely identifies the ventilation device 10 and a status indicating whether the ventilation device 10 is on (operating) or off (stopped operating).

[0032] The information output system 1000 includes a server device 7 .

[0066] The first management DB 712 is a database for managing the detection results of the differential pressure sensor 9, and has a record R1 for each examination room ER. The record R1 includes an examination room ID that uniquely identifies the examination room ER, the sensor ID of the differential pressure sensor 9, and the first upload data D1.

[0067] The second management DB 713 is a database for managing the status of the ventilation device 10, and has a record R2 for each ventilation device 10. The record R2 has the device ID of the ventilation device 10, the second upload data D2, and the examination room ID of the examination room ER to be ventilated by the ventilation device 10. The record R2 has one or more examination room IDs.

[0068] The third management DB 714 is a database for managing communication data for communicating with the output device 4, and has a record R3 for each examination room ER. Record R3 includes an examination room ID, indicator light communication data, first terminal communication data, and second terminal communication data. The indicator light communication data is data for communicating with the indicator light 1, and an example of this is a predetermined address. The first terminal communication data is data for communicating with the first terminal device 2, and an example of the data is a predetermined address. The second terminal communication data is data for communicating with the second terminal device 3, and an example of this is a predetermined address.

[0069] In addition, the first terminal communication data and the second terminal communication data corresponding to the examination room ID in record R3 are appropriately updated at a predetermined timing so as to become the communication data of the terminal device 5 used by doctor D who examines in the examination room ER.

[0070] The server communication unit 71 includes communication hardware such as a communication circuit, and communicates with the output device 4, the third terminal device 8, the differential pressure sensor 9, and the ventilator 10 under the control of the server control device 70. The communication standard of the server communication unit 71 may be a wireless communication standard or a wired communication standard.

[0071] The server processor 700 reads and executes a control program 711 stored in the server memory 710 to function as a server communication control unit 701, an update unit 702, a first determination unit 703, a second determination unit 704, and an estimation unit 705.

[0072] The server communication control unit 701 communicates with the output device 4, the third terminal device 8, the differential pressure sensor 9, and the ventilation device 10 via the server communication unit 71.

[0073] The update unit 702 updates the contents of record R1. When the server communication control unit 701 receives first upload data D1, the update unit 702 identifies record R2 of the sensor ID included in the received first upload data D1 from the first management DB 712. Then, the update unit 702 updates the first upload data D1 of the identified record R2 to the received first upload data D1. The update unit 702 updates the contents of record R2. When the server communication control unit 701 receives second upload data D2, the update unit 702 identifies record R2 of the device ID included in the received second upload data D2 from the second management DB 713. Then, the update unit 702 updates the second upload data D2 of the identified record R2 to the received second upload data D2.

[0074] The first determination unit 703 determines whether the examination room ER is at a positive pressure or a negative pressure relative to the waiting room WR. That is, the first determination unit 703 determines whether the examination room ER is at a higher pressure or a lower pressure than the waiting room WR. The first determination unit 703 reads the first upload data D1 for each examination room ER from the first management DB 712, and performs a determination based on the read first upload data D1. If the detection result of the differential pressure sensor 9 recorded in the read first upload data D1 is a positive value, the first determination unit 703 determines that the examination room ER is at a positive pressure relative to the waiting room WR, that is, the examination room ER is at a higher pressure than the waiting room WR. If the detection result of the differential pressure sensor 9 recorded in the read first upload data D1 is a negative value, the first determination unit 703 determines that the examination room ER is at a negative pressure relative to the waiting room WR, that is, the examination room ER is at a lower pressure than the waiting room WR.

[0075] The second determination unit 704 determines whether the ventilator 10 is operating or stopped. The second determination unit 704 reads the second upload data D2 from the second management DB 713, and makes a determination based on the read second upload data D2. If the status recorded in the read second upload data D2 indicates that the ventilator 10 is on, the second determination unit 704 determines that the ventilator 10 is operating. On the other hand, if the status recorded in the read second upload data D2 indicates that the ventilator 10 is off, the second determination unit 704 determines that the ventilator 10 is stopped.

[0076] The estimation unit 705 estimates the wind speed in the predetermined area SAR. The predetermined area SAR is an area in the examination room ER between the patient P and the doctor D. More specifically, the predetermined area SAR is an area between the first seat CR1 and the second seat CR2. The estimation unit 705 estimates the wind speed in the predetermined area SER based on the detection result of the differential pressure sensor 9 recorded in the first upload data D1. The estimation unit 705 estimates the wind speed in the predetermined area SER by referring to a table. This table is data in which the differential pressure and the wind speed are associated in a matrix form, and is stored in the server memory 710. The correspondence relationship between the differential pressure and the wind speed in this table is determined in advance by prior testing or simulation. The estimation unit 705 estimates the wind speed in the predetermined area SER by acquiring the wind speed associated with the differential pressure indicated by the detection result of the differential pressure sensor 9 from the table.

[0077] The estimation method of the estimation unit 705 is not limited to the method of referring to a table. The estimation unit 705 may estimate the wind speed corresponding to the detection result of the differential pressure sensor 9 using an algorithm that is determined in advance by a prior test or simulation. The estimation unit 705 may also estimate the wind speed corresponding to the detection result of the differential pressure sensor 9 using a learning model that has machine-learned the relationship between the differential pressure and the wind speed.

The operation shown in FIG. 6 is executed for each examination room ER.

[0081] The server device 7 starts the operation of the flowchart FA when a predetermined trigger occurs. Examples of the predetermined trigger include the passage of a predetermined period, or the update of the first upload data D1 managed by the first management DB 712.

[0082] The first determination unit 703 reads out records R1, R2, and R3 having the same examination room ID from the first management DB 712, the second management DB 713, and the third management DB 714 (step SA1).

[0083] Next, the first determination unit 703 determines whether the examination room ER is at a positive pressure or a negative pressure with respect to the waiting room WR, based on the first upload data D1 of the record R1 read in step SA1 (step SA2).

[0084] If the first judgment unit 703 judges that the examination room ER is at positive pressure relative to the waiting room WR (step SA2: positive pressure), the estimation unit 705 estimates the wind speed in the specified area SER based on the first upload data D1 of the record R1 read in step SA1 (step SA3).

[0085] Next, the server communication control unit 701 transmits the first display data to the terminal device 5 (step SA4).

[0086] Next, the server communication control unit 701 transmits the first turn-on instruction data to the indicator light 1 (step SA5). The first turn-on instruction data is data instructing the indicator light 1 to turn on the indicator light 1 to indicate that the airflow conditions in the examination room ER are normal. In step SA5, the server communication control unit 701 transmits the first turn-on instruction data based on the indicator light communication data of record R3 read in step SA1.

[0087] Returning to the explanation of step SA2, if the first judgment unit 703 judges that the examination room ER is at negative pressure relative to the waiting room WR (step SA1: negative pressure), the second judgment unit 704 judges whether the ventilation device 10 is on or off based on the second upload data D2 of the record R2 read in step SA1 (step SA6).

[0088] Next, the server communication control unit 701 transmits second display data to the terminal device 5 (step SA7).

In step SA7, the server communication control unit 701 transmits second turn-on instruction data based on the first terminal communication data and the second terminal communication data of record R3 read out in step SA1.

[0089] Next, the server communication control unit 701 transmits second turn-on instruction data to the indicator light 1 (step SA8). The second turn-on instruction data is data instructing the indicator light 1 to turn on the indicator light 1 to indicate that the airflow condition in the examination room ER is abnormal. In step SA8, the server communication control unit 701 transmits the second turn-on instruction data based on the indicator light communication data of record R3 read in step SA1.

[0090] As shown in the flowchart FB, the application executing unit 501 receives the first display data or the second display data from the server device 7 (step SB1).

[0091] Next, the application executing unit 501 displays the first screen G1 or the second screen G2 (step SB2). More specifically, if the first application executing unit 201 receives the first display data in step SB1, it displays the first screen G1 on the touch panel 22, and if the first application executing unit 201 receives the second display data in step SB1, it displays the second screen G2 on the touch panel 22.

[0093] The first screen G1 has positive pressure information J2. The positive pressure information J2 is information indicating that the air pressure in the examination room ER is higher than the air pressure in the waiting room WR, in other words, the examination room ER is at a positive pressure relative to the waiting room WR. In FIG. 7, the symbol string "Room pressure ○ Positive pressure" is the positive pressure information J2.

[0094] The first screen G1 has wind speed information J3. The wind speed information J3 is information that indicates the wind speed in the specified area SER. In FIG. 7, the symbol string "Wind speed ○ 0.2 m / sec" is the wind speed information J3. The wind speed information J3 includes an alert regarding the wind speed in the specified area SER if the wind speed in the specified area SER is equal to or lower than a specified value. For example, the first screen G1 in this case has wind speed information J3 that includes an "X" symbol instead of an "○" symbol as an alert regarding the wind speed in the specified area SER. The wind speed information J3 is an example of "information about wind speed."

[0095] The first screen G1 also has a normal state image SG. The normal state image SG is an image indicating that the airflow situation in the examination room ER is normal, that is, an image indicating that the examination room ER is at a positive pressure relative to the waiting room WR. The normal state image SG includes an examination room image ERG indicating the examination room ER, a first airflow image KG1, a second airflow image KG2, and a third airflow image KG3.

[0096] The examination room image ERG shows the examination room ER viewed from a specific viewpoint.

The first airflow image KG1 is superimposed on the examination room image ERG to show the airflow flowing from the air intake port AI through the exhaust port EP and out into the waiting room WR.

[0098] The second airflow image KG2 is an image showing an airflow from the doctor D to the patient P. The size of the second airflow image KG2 may be a size according to the magnitude of the wind speed in the predetermined area SER estimated by the estimation unit 705, or may be a fixed size. In FIG. 7, an image of an arrow is given as an example of the second airflow image KG2, but the second airflow image KG2 may be an image shown by lines and dots, similar to the first airflow image KG1. The second airflow image KG2 is displayed superimposed on the examination room image ERG, between the doctor D and the patient P shown in the examination room image ERG.

[0099] The third airflow image KG3 is an image showing the airflow of the exhaled breath of the patient P. The third airflow image KG3 shows the airflow moving from the patient P to the doctor D and being pushed back toward the patient P on the way without reaching the doctor D. The third airflow image KG3 is displayed superimposed on the examination room image ERG, between the patient P and the doctor D shown in the examination room image ERG.

[0100] When the application execution unit 501 receives the first display data in step SB1, it generates a first screen G1 based on the received first display data as follows, and displays the generated first screen G1.

[0101] The application executing unit 501 generates normality information J1. Furthermore, the application executing unit 501 generates positive pressure information J2. The application executor 501 also determines whether the wind speed in the specified area SER recorded in the received first display data is equal to or less than a specified value. If the application executor 501 determines that the wind speed is equal to or less than the specified value, the application executor 501 generates wind speed information J3 that includes an alert and indicates the wind speed recorded in the first display data. On the other hand, if the application executor 501 determines that the wind speed is greater than the specified value, the application executor 501 generates wind speed information J3 that does not include an alert and indicates the wind speed recorded in the first display data. Furthermore, the application executing unit 501 generates a normal state image SG. Note that image data of the normal state image SG may be downloaded when the display application 511 is installed, or may be included in the first display data. Then, the application executing unit 501 generates a first screen G1 including the generated normality information J1, positive pressure information J2, wind speed information J3, and normal state image SG.

[0102] FIG. 8 is a diagram showing an example of the second screen G2. The second screen G2 has abnormality information J4 indicating that the airflow condition in the examination room ER is abnormal.

[0103] The second screen G2 has confirmation prompt information J5. The confirmation prompt information J5 is information indicating the cause of the abnormality in the airflow condition in the examination room ER and a prompt to confirm the cause. In Fig. 8, the confirmation prompt information J5 is a character string saying "Please check that the ventilation is running and that the windows and doors are open." Note that the cause of the abnormality that the confirmation prompt information J5 prompts to confirm is not limited to the cause shown in Fig. 8, and may further or instead include other causes such as a breakdown of the ventilation device 10 or a clogged filter provided in the ventilation device 10.

[0104] The second screen G2 has operation prompt information J6 when the ventilation device 10 is off. The operation prompt information J6 is information that prompts the user to operate the ventilation device 10. In Fig. 8, the character string "Ventilation appears to be off. Please turn ventilation on" is the operation prompt information J6.

[0105] The second screen G2 has an abnormality image IG. The abnormality image IG is an image showing that the airflow situation in the examination room ER is abnormal, that is, an image showing that the examination room ER is under negative pressure relative to the waiting room WR. The abnormality image IG includes an examination room image ERG and a fourth airflow image KG4.

[0106] The fourth airflow image KG4 is an image showing the airflow from the patient P to the doctor D. In Fig. 8, an image of an arrow is given as an example of the fourth airflow image KG4, but the fourth airflow image KG4 may be an image shown by lines and dots, similar to the first airflow image KG1. The fourth airflow image KG4 is displayed superimposed on the examination room image ERG.

[0107] When the application execution unit 501 receives the second display data in step SB1, the application execution unit 501 generates the second screen G2 based on the received second display data as follows, and displays the generated second screen G2.

[0108] The application executing unit 501 generates anomaly information J4. The application execution unit 501 also generates confirmation prompt information J5. Furthermore, when the determination result of the second determination unit 704 recorded in the received second display data indicates that the ventilation device 10 is off, the application executor 501 generates operation prompt information J6. On the other hand, when the determination result of the second determination unit 704 recorded in the received second display data indicates that the ventilation device 10 is on, the application executor 501 does not generate operation prompt information J6. Furthermore, the application executing unit 501 generates an abnormality image IG. Note that image data of the abnormality image IG may be downloaded when the display application 511 is installed, or may be included in the second display data. If the application executing unit 501 has not generated the action prompt information J6, it generates the second screen G2 including the generated anomaly information J4, confirmation prompt information J5, and anomaly image IG. On the other hand, if the application executing unit 501 has generated the action prompt information J6, it generates the generated anomaly information J4, confirmation prompt information J5, action prompt information J6, and anomaly image IG.

[0109] Returning to the explanation of FIG. 6, as shown in the flow chart FC, the indicating lamp communication control section 101 receives the first turn-on instruction data or the second turn-on instruction data from the server device 7 (step SC1).

[0110] Next, the lighting control unit 102 turns on the light 13 in the first or second lighting state (step SB2). The first lighting state indicates that the airflow situation in the examination room ER is normal, for example, a green lighting state. The second lighting state indicates that the airflow situation in the examination room ER is abnormal, for example, a red lighting state.

[0111] In step SB2, if the first lighting instruction data is received in step SC1, the lighting control unit 102 performs the first lighting. Also, in step SB2, if the second lighting instruction data is received in step SC1, the lighting control unit 102 performs the second lighting.

[0112] As described above, when the examination room ER is at a positive pressure relative to the waiting room WR, the output device 4 outputs information that the airflow conditions in the examination room ER are normal. This allows the doctor D who examines patients in the examination room ER to know that the airflow conditions in the examination room ER are normal, that is, that the risk of infection from the patient P waiting in the waiting room WR is low. Therefore, the doctor D who examines patients in the examination room ER can examine them in the examination room ER with peace of mind. Furthermore, when the examination room ER is at negative pressure relative to the waiting room WR, the output device 4 outputs a message indicating that the airflow conditions in the examination room ER are abnormal. This allows doctor D, who is examining a patient in the examination room ER, to know that the airflow conditions in the examination room ER are abnormal, that is, that there is a high risk of infection from patient P waiting in the waiting room WR and that infection control measures are necessary. Therefore, doctor D, who is examining a patient in the examination room ER, can know that infection control measures are necessary if they are necessary in the examination room ER.

[0113] [1-2-2. Operation of the server device and the third terminal device] First, the operations of the server device 7 and the third terminal device 8 will be described.

[0114] Fig. 9 is a diagram showing the operations of the server device 7 and the third terminal device 8. In Fig. 9, a flowchart FD shows the operations of the server device 7, and a flowchart FE shows the operations of the third terminal device 8. Note that the operations shown in Fig. 9 are executed for each examination room ER, and are performed in parallel with the operations shown in Fig. 6.

[0115] In the flowchart shown in FIG. 9, the same steps as those in the flowchart shown in FIG. 6 are denoted by the same reference numerals, and detailed description thereof will be omitted where appropriate.

[0116] The server device 7 starts the operation of the flowchart FD when a predetermined trigger occurs. This predetermined trigger is the same trigger as the trigger that starts the operation of the flowchart FA.

[0117] When the first determination unit 703 determines that the examination room ER is at a positive pressure relative to the waiting room WR (step SA2: positive pressure), the server communication control unit 701 transmits third display data to the third terminal device 8 (step SD1). The third display data is data related to the display of the third screen G3, and records the examination room ID of the record read out in step SA1 and the fact that the examination room ER is at a positive pressure relative to the waiting room WR.

[0118] In step SD1, the server communication control unit 701 transmits the third display data to the third terminal device 8 based on the third terminal communication data for communicating with the third terminal device 8. The third terminal communication data is, for example, an address, and is stored in the server memory 710.

[0119] On the other hand, if the first determination unit 703 determines that the examination room ER is at negative pressure relative to the waiting room WR (step SA2: negative pressure), the server communication control unit 701 transmits fourth display data to the third terminal device 8 (step SD2). The third display data is data related to the display of the third screen G3, and records the examination room ID of the record read out in step SA1 and the fact that the examination room ER is at negative pressure relative to the waiting room WR.

[0120] In step SD2, the server communication control section 701 transmits the fourth display data to the third terminal device 8 based on third terminal communication data for communicating with the third terminal device 8.

[0121] As shown in flowchart FE, the third application executing unit 801 receives the third display data or the fourth display data from the server device 7 (step SE1).

[0122] Next, the third application executing unit 801 changes the display content of the third screen G3 (step SE2).

[0123] Step SE2 will be described in detail while explaining the third screen G3. FIG. 10 is a diagram showing an example of the third screen G3.

[0124] The third screen G3 has a hospital image HG. The hospital image HG is an image that shows the inside of the hospital H as viewed from a specific viewpoint. In this embodiment, the inside of the hospital H shown in the hospital image HG of the third screen G3 includes a waiting room WR, a plurality of examination rooms ER, a reception room RE, and a room RO.

[0125] When the examination room ER is at a negative pressure relative to the waiting room WR, the third screen G3 displays an alert image AR superimposed on an area on the hospital image HG corresponding to the negative pressure examination room ER. The alert image AR is an image that warns about the airflow situation in the examination room ER. Note that the alert image AR shown in FIG. 3 is a combination of a speech bubble and an exclamation mark, but the picture of the alert image AR is not limited to this. On the other hand, when the examination room ER is at a positive pressure relative to the waiting room WR, the third screen G3 does not superimpose the alert image AR on the area corresponding to the examination room ER at a positive pressure.

[0126] In the hospital image HG, an area for displaying an alert image AR is set in an image region corresponding to each of a plurality of examination rooms ER. In the image data of the hospital image HG, a correspondence relationship between the area and the examination room ID is recorded for each area. When the third display data is received in step SE1, the third application executing unit 801 does not display the alert image AR in the area corresponding to the examination room ID recorded in the third display data. On the other hand, when the third application executing unit 801 receives the fourth display data in step SE2, it displays an alert image AR in the area corresponding to the examination room ID recorded in the fourth display data.

[0127] As described above, the third terminal device 8 displays the third screen G3 which shows a schematic diagram of the inside of the hospital H. When the examination room ER is at negative pressure relative to the waiting room WR, an alert image AR is displayed superimposed on the corresponding examination room ER on the third screen G3. This allows the medical staff HC of the hospital H to know the airflow conditions in each examination room ER. Therefore, the medical staff HC of the hospital H can easily know whether there is an examination room ER that requires infection control measures, and which examination room ER requires infection control measures.

[0128] [1-3. Effects, etc.] As described above, the information output system 1000 for hospital H includes a differential pressure sensor 9 that detects the difference between the air pressure in the examination room ER where doctor D performs the examination and the air pressure in the waiting room WR adjacent to the examination room ER where patient P waits, and an output device 4 used in hospital H. When the detection result of the differential pressure sensor 9 indicates that the pressure is higher in the examination room ER than in the waiting room WR, the output device 4 outputs that the airflow conditions in the examination room ER are normal. In addition, when the detection result of the differential pressure sensor 9 indicates that the pressure is lower in the examination room ER than in the waiting room WR, the output device 4 outputs that the airflow conditions in the examination room ER are abnormal.

[0129] According to this, in a situation where an air current is generated from the examination room ER toward the waiting room WR, Doctor D can know that the air current condition in the examination room ER is normal, so Doctor D can provide medical care with peace of mind. Also, in a situation where an air current is generated from the waiting room WR toward the examination room ER, Doctor D can know that infection control measures are necessary in the examination room ER. Therefore, Doctor D can provide medical care with peace of mind, and can know that infection control measures are necessary if necessary.

[0130] In the examination room ER, there are disposed a first seat CR1 where the patient P sits, and a second seat CR2 where the doctor D sits. The second seat CR2 is disposed at a position farther from the waiting room WR than the first seat CR1.

[0131] In an examination room ER with this layout, in a situation where air currents are generated from the waiting room WR toward the examination room ER, there is a higher risk of infection from the patient P. In this embodiment, if it is indicated that the pressure is higher in the examination room ER than in the waiting room WR, an output is issued indicating that the air current conditions in the examination room ER are normal, so that the doctor D can provide medical care with peace of mind even in a space with a higher risk of infection.

[0132] When the detection result of the differential pressure sensor 0 indicates that the pressure in the examination room ER is lower than that in the waiting room WR, the terminal device 5 outputs the reason why the airflow conditions in the examination room ER are abnormal and a prompt to confirm the reason.

[0133] This increases the likelihood that Doctor D will be able to quickly identify the cause of the abnormality. This allows Doctor D to quickly take infection control measures, thereby reducing the risk of infection in the ER.

[0134] The information output system 1000 for the hospital H includes a ventilator 10 that ventilates the examination room ER. When the detection result of the differential pressure sensor 9 indicates that the pressure in the examination room ER is lower than that in the waiting room WR and the ventilator 10 is stopped, the terminal device 5 further outputs a message urging the user to operate the ventilator 10.

[0135] This allows Doctor D to easily understand what infection control measures should be taken. Therefore, Doctor D can take infection control measures promptly, and the risk of infection in the ER can be further reduced.

[0136] When the detection result of the differential pressure sensor 9 indicates that the pressure is higher in the examination room ER than in the waiting room WR, the terminal device 5 displays on the display unit 52 a first airflow image KG1 indicating the airflow flowing from the examination room ER to the waiting room WR.

[0137] This allows Doctor D to intuitively understand that the risk of infection from patients in the waiting room WR is low. Therefore, Doctor D can provide medical care with greater peace of mind.

[0138] The terminal device 5 displays, on the display unit 52, a second airflow image KG2 showing the airflow from the doctor D to the patient P when the detection result of the differential pressure sensor 9 indicates that the pressure is higher in the examination room ER than in the waiting room WR.

[0139] This allows Doctor D to intuitively understand that the risk of infection from Patient P in the ER is low. Therefore, Doctor D can provide medical care with greater peace of mind.

[0140] The information output system 1000 for the hospital H includes an estimation unit 705 that estimates the wind speed in a predetermined area SER in the examination room ER based on the detection result of the differential pressure sensor 9. The predetermined area SER is an area between the doctor D and the patient P. The terminal device 5 outputs information related to the wind speed estimated by the estimation unit 705.

[0141] This allows Doctor D to intuitively understand how low the risk of infection from Patient P in the ER is. Therefore, Doctor D can provide medical care with greater peace of mind.

[0142] The information output system 1000 for the hospital H includes an estimation unit 705 that estimates the wind speed in a predetermined area SER in the examination room ER based on the detection result of the differential pressure sensor 9. The predetermined area SER is an area between a doctor D and a patient P. The terminal device 5 outputs an alert regarding the wind speed when the wind speed estimated by the estimation unit 705 is equal to or lower than a predetermined value.

[0143] This makes it possible to ascertain whether infection control measures are necessary from patient P in the ER examination room.

[0144] In the information output method for hospital H, when the detection result of the differential pressure sensor 9, which detects the difference between the air pressure in the examination room ER where doctor D performs the examination and the air pressure in the waiting room WR adjacent to the examination room ER where patient P waits, indicates that the pressure in the examination room ER is higher than that in the waiting room WR, the output device 4 used in hospital H outputs that the airflow conditions in the examination room ER are normal.In the information output method for hospital H, when the detection result of the differential pressure sensor 9 indicates that the pressure in the examination room ER is lower than that in the waiting room WR, the output device 4 outputs that the airflow conditions in the examination room ER are abnormal.

[0145] According to this, the same effects as those of the information output system 1000 for Hospital H described above can be achieved.

[0146] The display application 511 causes the terminal processor 500 of the terminal device 5 used in the hospital H to output a message indicating that the airflow conditions in the examination room ER are normal when the detection result of the differential pressure sensor 9 indicates that the pressure is higher in the examination room ER than in the waiting room WR, and causes the terminal processor 500 to output a message indicating that the airflow conditions in the examination room ER are abnormal when the detection result of the differential pressure sensor 9 indicates that the pressure is lower in the examination room ER than in the waiting room WR.

[0147] According to this, the same effects as those of the information output system 1000 for Hospital H described above can be achieved.

[0148] (Other embodiments) As described above, the above-mentioned first embodiment has been described as an example disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the above-mentioned first embodiment to create a new embodiment. Therefore, other embodiments will be exemplified below.

[0149] In the above-described embodiment, when the examination room ER is at negative pressure relative to the waiting room WR, an output is generated indicating that the airflow conditions in the examination room ER are abnormal. In another embodiment, when the examination room ER is at negative pressure relative to the waiting room WR for a predetermined period of time (e.g., 20 seconds) or more, an output indicating that the airflow conditions in the examination room ER are abnormal may be generated. This predetermined period is, for example, the opening time of the door DR required to enter and exit the examination room ER, and is determined in advance through prior testing or simulation. According to this other embodiment, it is possible to suppress erroneous detection by the differential pressure sensor 9 due to the opening of the door DR when entering and exiting the examination room ER, and to suppress erroneous output indicating that the airflow conditions in the examination room ER are abnormal.

[0150] In the embodiment described above, when the examination room ER is at a negative pressure relative to the waiting room WR and the ventilation device 10 is off, the abnormality information J4, the confirmation prompt information J5, and the action prompt information J6 are displayed. In another embodiment, the above may be configured to display only the action prompt information J6 when the examination room ER is at a negative pressure relative to the waiting room WR and the ventilation device 10 is off.

[0151] In the above embodiment, the hospital H that provides medical care to patients is exemplified as the "hospital", but the "hospital" is not limited to the hospital H that provides medical care to patients, and may be a veterinary hospital that provides medical care to sick animals. Note that sick animals refer to animals (excluding humans) that are suffering from an illness.

[0152] In the above-described embodiment, the examination room ER is exemplified as the "first space" and the waiting room WR is exemplified as the "second space". In other embodiments, the "first space" may be the reception room RE and the "second space" may be the waiting room WR. In other embodiments, the "first space" may be the first waiting room and the "second space" may be the second waiting room. The second waiting room is a waiting room WR exclusively for patients P with fever symptoms, and the first waiting room is a waiting room WR for patients P other than the patient P waiting in the second waiting room. According to this other embodiment, in a situation where an airflow is generated from the first waiting room to the second waiting room, the medical staff HC of the hospital H can know that the airflow situation in the first waiting room is normal. According to this other embodiment, in a situation where an airflow is generated from the second waiting room to the first waiting room, an alert is output about the airflow situation in the first waiting room, so that the medical staff HC of the hospital H can know that infection control is necessary in the first waiting room. Therefore, according to this other embodiment, it is easy to know whether infection control is necessary between patients P.

[0153] In the above-described embodiment, the differential pressure sensor 9 indirectly detects whether or not an airflow is generated from the examination room ER to the waiting room WR. In another embodiment, an airflow sensor or an anemometer may be used to detect whether or not an airflow is generated from the examination room ER to the waiting room WR. The information output system 1000 in this other embodiment is equipped with an airflow sensor or an anemometer instead of the differential pressure sensor 9. In addition, the output device 4 in this other embodiment outputs a message indicating that the airflow situation in the examination room ER is normal when the airflow sensor or anemometer detects that an airflow is generated from the examination room ER to the waiting room WR. In addition, the output device 4 in this other embodiment outputs a message indicating that the airflow situation in the examination room ER is abnormal when the airflow sensor or anemometer detects that an airflow is generated from the waiting room WR to the examination room ER.

[0154] The information output system 1000 of the above-mentioned embodiment is a system applied to the hospital H, but the facility to which the information output system 1000 is applied is not limited to the hospital H. The facility to which the information output system 1000 is applied may be a facility having an adjacent space, such as a nursing home for the elderly, a midwifery clinic, a pharmacy, or other medical institution, a store, or a food factory. For example, if the facility to which the information output system 1000 is applied is a food factory, the food factory has a storage space in which food is stored and a space adjacent to the storage space. The information output system 1000 applied to the food factory can contribute to preventing dust and dirt from flowing into the storage space by outputting the airflow status of the storage space as in the above-mentioned embodiment 1, and can also contribute to preventing mold and condensation from occurring in the storage space.

[0155] In the embodiment described above, the information output system 1000 is configured so that the indicator light 1 and the terminal device 5 exist as the output device 4. In other embodiments, the information output system 1000 may be configured so that there is only the terminal device 5 without the indicator light 1, or so that there is only the indicator light 1 without the terminal device 5.

[0156] The indicator light processor 100, the first terminal processor 200, the second terminal processor 300, the third terminal processor 800, and the server processor 700 may be configured by a single processor or by multiple processors. These processors may be hardware programmed to realize the corresponding functional units. That is, these processors may be configured by, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0157] The configuration of each part of the information output system 1000 shown in Figures 4 and 5 is an example, and the specific implementation form is not particularly limited. In other words, it is not necessarily necessary to implement hardware corresponding to each part individually, and it is also possible to implement a configuration in which one processor executes a program to realize the function of each part. Also, some of the functions realized by software in the above-mentioned embodiment may be hardware, or some of the functions realized by hardware may be software.

[0158] The step units of the operations shown in Figures 6 and 9 are divided according to the main processing contents in order to make the operations easier to understand, and the operation is not limited by the way in which the processing units are divided or the names of the processing units. The operations may be divided into more step units according to the processing contents. Furthermore, one step unit may be divided so as to include more processing. Furthermore, the order of the steps may be appropriately changed within a range that does not interfere with the purpose of this disclosure.

[0159] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents.
