Description

  The present invention relates to an information presentation system, and more particularly to an information presentation system that presents information useful for the business to users such as nurses, caregivers, and factory workers.

  A user who is busy or cannot tolerate mistakes, such as a nurse, may not be able to respond to the information presentation (or the contents of the information) even if the information useful or necessary for the work is presented. ， Present information presentation may be wasted. In addition, if information is presented when the user is performing a task requiring concentration, the user may be upset by the information presentation or disturb the concentration. There is a risk of inducing user mistakes. Therefore, it is very important in presenting information to consider the situation of the user who receives information.

Therefore, for example, Patent Document 1 proposes a technique for presenting information in consideration of the user's situation. The technique of Patent Document 1 is an erroneous operation alarm system that gives an alarm (that is, presents information) when an operator is about to perform an erroneous operation, and monitors the operator's work status when giving an alarm. Based on the monitor information obtained in this way, it is determined whether or not an alarm can be given to the worker. And when giving a warning affects an operator's work, it is made not to give a warning.
JP 2006-215680 A [G06F 17/60]

  However, in the technique of Patent Document 1, when it is determined that the worker cannot be warned, the warning is not given, that is, the information is not transmitted unless the erroneous work leads to a serious accident. ing. Therefore, in the technique of Patent Document 1, information to be transmitted may not be appropriately transmitted to the user.

  Therefore, a main object of the present invention is to provide a novel information presentation system.

  Another object of the present invention is to provide an information presentation system capable of presenting information to a user at an appropriate timing and reliably transmitting information.

  The present invention employs the following configuration in order to solve the above problems. Note that reference numerals in parentheses and supplementary explanations indicate correspondence with embodiments described later in order to help understanding of the present invention, and do not limit the present invention.

  1st invention is detected by the user selection means which selects the user who should present information when the information to present occurs, the situation detection means which detects the situation of the user selected by the user selection means, and the situation detection means When it is determined that the information can be presented to the user by the presentation judging means for judging whether or not the information can be presented to the user based on the user's situation and the content of the information Information presentation means for presenting information to the user, standby means for waiting for a predetermined time when it is determined that the information cannot be presented to the user by the presentation judgment means, and for the user during the standby by the standby means It is an information presentation system provided with a retry means for retrying determination processing for determining whether or not information can be presented at least once.

  In the first invention, the information presentation system (10) is applied to, for example, a hospital and presents useful information to a user (nurse) who works there. The user selection means (12, 34, S3) selects a user who should present information. The presentation determination means (12, 26, S23) is a user situation detected by the situation detection means (12, 28, 30, 32, S21), for example, the user's work situation (work load or busyness), and information to be presented. Whether or not it is in a state in which information can be presented to the user is determined based on the content (urgency) of the user. When the information can be presented to the user, the information presenting means (12, 16, S33) visually displays the information, for example. Even when it is determined that the information cannot be presented to the user when the information to be presented is generated, the standby means (12, 34, S25, S27) waits for a predetermined time, The determination process for determining whether or not information can be presented to the user is retried by the retry means (12, 26, S23). When information can be presented to the user, information is presented by the information presenting means.

  According to the first invention, even when it is determined that information to be presented cannot be presented to the user when the information to be presented is generated, the information can be presented to the user after waiting for a predetermined time. See how it changes to state. Since the information is presented when the information can be presented, the information can be presented at an appropriate timing for the user, and the information can be reliably transmitted.

  The second invention is dependent on the first invention and further comprises a situation change judging means for judging whether or not the user's situation detected by the situation detecting means has changed, and the situation change judgment during standby by the waiting means. When it is determined by the means that the situation of the user has changed, the retry means retry the determination process.

  In the second invention, a situation change judging means (12, S29) is further provided, and whether or not the user situation detected by the situation detecting means (12, 28, 30) has changed, for example, the user's business is changed. Determine whether or not. For example, when there is a change in the user's business, determination processing by the retry means (12, 26, S23) is executed at that time. Therefore, the determination process by the retry means is performed at an appropriate timing, and the processing load can be reduced.

  The third invention is dependent on the first or second invention, and when it is determined that the information can be presented to the user by the retry means even if the waiting means waits for a predetermined time, the user selection The means selects other users to present information.

  In the third invention, if the information cannot be presented even after waiting for a predetermined time, another user is selected and information is presented to the other user. For example, in the case of a user who cooperates with multiple people like a nurse, even if information cannot be presented to the main user who should present the information, By presenting, the instruction (business) included in the information is surely executed by another user.

  According to the third invention, even when information cannot be presented to the main user who should present the information, information can be transmitted more reliably because other users are selected and presented. it can.

  The fourth invention is dependent on any one of the first to third inventions, further comprising response determination means for determining whether or not there is an acknowledgment from the user when the information is presented by the information presentation means, and the user The selecting means selects another user who should present information when the response determining means determines that there is no positive response.

  In the fourth aspect of the invention, response determination means (12, S35) is further provided, and whether or not there is an acknowledgment (Ack) from the user when information is presented by the information presentation means (12, 16, S33). to decide. That is, it is confirmed that information is transmitted to the user or that the user can execute an instruction (work) included in the information. If there is no positive response from the user, another user is selected and information is presented to the other user.

  According to the fourth invention, even when information is presented to the user, when there is no positive response from the user, information is presented to other users, so that information can be transmitted more reliably. . Moreover, it can confirm that the instruction | indication contained in the information is performed.

  A fifth invention is dependent on any one of the first to fourth inventions, and the information presenting means includes notifying means capable of notifying the user that information is being presented by a plurality of methods, and provides information to the user. A notification method selection unit that selects a notification method according to the user's situation detected by the situation detection unit when presenting, and the notification unit displays information to the user by the notification method selected by the notification method selection unit; Notify that there is.

  In the fifth invention, the information presenting means (12, 16, S33) includes notifying means capable of notifying that there is information presenting by a plurality of methods such as a method using vibration, sound and light. Further, notification information selection means (12, 16, S31) is further included, and an appropriate notification method is selected according to the user's situation including the surrounding situation.

  According to the fifth aspect of the invention, the user is notified that there is information presentation by a notification method appropriate to the situation at that time, so that information can be transmitted more reliably.

  According to the present invention, even when it is determined that information to be presented cannot be presented to the user at the time when the information to be presented is generated, the information can be presented to the user by waiting for a predetermined time. Watch how it doesn't change. Since the information is presented when the information can be presented, the information can be presented at an appropriate timing for the user, and the information can be reliably transmitted.

  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  Referring to FIG. 1, an information presentation system (hereinafter simply referred to as “system”) 10 according to an embodiment of the present invention includes a server 12, and is applied to a hospital, for example, and a nurse (user) working there. Provide useful information (advice) at an appropriate time.

  The server 12 is connected to a plurality of nurse terminals (hereinafter simply referred to as “terminals”) 16, a plurality of passage sensors 18, and a plurality of repeaters 20 via a wired or wireless communication line (network) 14. . The terminal 16 is a portable terminal such as a PDA or PHS, and is assigned to each nurse. The passage sensor 18 is a light receiving device that receives infrared rays, and is disposed at the entrance and exit of each room such as a corridor in a ward that accommodates inpatients, an examination room, an operating room, a toilet, a staircase, a hospital room, and a nurse's office. The The repeater 20 is a portable terminal such as a PDA or a portable computer, and is assigned to each nurse.

  FIG. 2 is a block diagram showing a specific configuration of the server 12. Although not shown in FIG. 1, a monitor device 22 is connected to the server 12. The monitor device 22 includes, for example, sensors such as a plurality of objective sensors, a plurality of sound collecting microphones (sound sensors), and a plurality of video cameras (image sensors). Although not shown in the drawings, in this embodiment, the plurality of objective sensors include a thermometer, a sphygmomanometer, a syringe, a drip syringe (injector), a blood collection test tube, a medical container such as a urinalysis cup. It is installed in the takeout part (entrance / exit) of the (hangar), the key of the storage box (hangar), the nurse call terminal, etc., and detects the presence or absence of use (removal) of those medical devices. However, identification information such as electronic tag information (RF-ID) or barcode is added to these medical instruments, and the presence or absence of use is detected by reading the electronic tag information and barcode. It may be.

  A plurality of sound collecting microphones are installed in a corridor and a hospital room (bed or the vicinity thereof) in a ward that accommodates hospitalized patients, and collects ambient sounds. In addition to the microphones, multiple video cameras are installed in hallways and hospital rooms, as well as in nurse stations, etc., and take pictures of nurses who perform nursing work. To do. Nursing services include interviews, temperature measurements, pressure measurements, injections, medications, infusions, discharge guidance, and so on.

  Although omitted in FIG. 1, six databases (DB) are connected to the server 12. Specifically, a nurse attribute DB 24, a knowledge DB 26, a nursing situation DB 28, a place DB 30, a schedule DB 32, and an advice DB 34 are connected to the server 12.

  The nurse attribute DB 24 records nurse attribute information for each nurse. Specifically, in association with each nurse's identification information (nurse ID), such as the nurse's name, department, group, age, gender, years of service, patient in charge, and equipment in charge of management, etc. Attribute information is stored as appropriate.

  In the knowledge DB 26, a work content recognition dictionary (template) for recognizing the work content performed by the nurse at that time, for example, from the monitor information from the repeater 20 (details will be described later) or the monitor device 22 acquired by the server 12. ) And various recognition dictionaries such as a work process recognition dictionary (template) for determining whether the process (procedure) performed by the nurse is correct or incorrect at that time. Also, in the knowledge DB 26, whether the information should be presented to the nurse by comparing the status of the nurse and the contents of the information presented to the nurse (urgency level), that is, presenting the information to the nurse Determination criterion data for determining whether or not it is possible is registered in advance.

  In the nursing status DB 28, information on the current working status of the nurse is recorded for each nurse. Specifically, information on the nurse's work status, including the nursing work currently being performed by the nurse and the progress status thereof, identified based on the monitor information from the repeater 20 and the monitor device 22, is provided for each nurse. It is written at any time in association with the identification information. Therefore, by referring to the nursing situation DB 28, the server 12 can recognize the current working situation (work load, busyness) of each nurse in real time.

  In the place DB 30, the current position (position information) of the nurse is recorded for each nurse. As will be described in detail later, the current position of the nurse is specified based on the detection information from the passage sensor 18 and is recorded in time series. Further, in the location DB 30, not only the position information of nurses but also the position information of doctors and patients, and further, medical instruments (things) are stored as appropriate. Since these pieces of position information are also updated as needed, the server 12 can recognize the current positions of the nurses and patients in real time by referring to the place DB 30.

  In the schedule DB 32, a schedule (worksheet) for the nurse's daily work is recorded for each nurse. In this schedule, the nursing work to be performed for the patient in charge of each nurse, the scheduled time (reminder information) for executing the nursing work, and the like are described. Nurses perform nursing work according to the worksheet, but if nursing work occurs that is not in the original worksheet, such as when a patient is requested to perform sudden nursing work, There are frequent cases where work does not proceed (start or end). In such a case, the worksheet is appropriately corrected automatically based on monitor information from the monitor device 20 or based on change information input by the nurse using the terminal 16 or the like. Therefore, the server 12 can recognize that information to be presented to the nurse has occurred (that is, there is reminder information to be presented at that time) with reference to the schedule DB 32. In the schedule DB 32, schedules for the entire hospital or departments, for example, reservation times for medical instruments and people (doctors and nurses) (time when movement of people is reserved for surgery, examinations, etc.) are appropriately selected. Described.

  The advice DB 34 stores information related to presentation information (advice) to be presented to the nurse. Although details will be described later, in the advice DB 34, when information to be presented is generated, conditions for selecting (searching) a nurse (presentation destination) to present the information, and the selected nurse For example, a trial time which is a time to try to present information is stored.

  The server 12 has a clock circuit 12a therein. The clock circuit 12a measures the date and time. In this embodiment, the server 12 refers to the clock circuit 12a, gives a time stamp to the nursing work currently being performed by the nurse and information on its progress, and moves the location of the nurse, medical equipment, and the like. A time stamp is added to the information, and it is determined whether it is the start time or end time of the nursing work described in the schedule.

  FIG. 3 is a block diagram showing an electrical configuration of the terminal 16. Referring to FIG. 3, terminal 16 includes a CPU 40, and memory 42, key switch 44, LCD driver 46, motor driver 50, wireless LAN 54 and amplifier 56 are connected to CPU 40. An LCD 48 is connected to the LCD driver 46, a vibration motor 52 is connected to the motor driver 50, and a speaker 58 is connected to the amplifier 56.

  As described above, when PHS is used as the terminal 16, a call (telephone) function is further added.

  The CPU 40 governs overall control of the terminal 16. The memory 42 includes a ROM and a RAM. In this embodiment, the terminal 16 mainly functions as an information presentation device, and the ROM stores a program for information presentation (information presentation program) and data necessary for information presentation (image data, sound data). ing. The RAM is used as a storage area, a work area, and a buffer area for the CPU 40.

  In this embodiment, programs and data necessary for presenting information are stored in the ROM, but may be downloaded from the server 12. In this way, the capacity of the ROM can be reduced.

  The key switch 44 is a variety of keys or buttons (switches) such as a cursor key such as a numeric keypad and a cross key and a selection key, and is used to input instructions from the nurse. The LCD driver 46 is a driving device for the LCD 48, and displays an image on the LCD 48 in accordance with an instruction from the CPU 40. In this embodiment, an information presentation screen 210 (see FIGS. 9 and 10) as will be described later is displayed on the LCD 48. The motor driver 50 is a driving device for the vibration motor 52, and drives the vibration motor 52 in accordance with an instruction from the CPU 40 to vibrate the terminal 16. The sound data (sound, voice or music) from the CPU 40 is converted into an analog sound (sound) signal, amplified by the amplifier 56, and output from the speaker 58.

  The wireless LAN 54 transmits an instruction input (command) input by the nurse using the key switch 44 to the server 12 via the network 14 in accordance with an instruction from the CPU 40. Although detailed description is omitted, since the server 12 manages the wireless LAN MAC address of the terminal 16 in association with the nurse ID, the user (nurse) of the terminal 16 that is communicating with the server 12 Can be recognized on the side. However, the nurse ID may be stored in the memory 42 (ROM), and the nurse ID may be transmitted to the server 12 together with the command. In addition, the wireless LAN 54 receives information (information related to screen display) transmitted from the server 12 and gives it to the CPU 40.

  As shown in FIG. 4, the passage sensor 18 includes a first light receiving module 72 and a second light receiving module 74. The first light receiving module 72 and the second light receiving module 74 are mounted on different side surfaces above the gate. Further, in the case 180 placed on the gate, components (CPU 70, RAM 76, wireless LAN 78: see FIG. 6) other than the light receiving modules (72, 74) of the passage sensor 18 are incorporated. However, the gates are only shown for easy understanding. Normally, the entrances and exits of rooms such as nurse stations, examination rooms, hospital rooms, corridors and corridors (crossroads, T-junctions, etc.), corridors The passage sensor 18 is installed at a key point such as a connecting portion with the stairs. If necessary, it may be installed at the gate of the elevator.

  In addition, as shown in FIG. 5, a transmitter 80 that transmits an infrared signal is attached to each nurse's head. For example, the transmitter 80 is fixed to a nurse cap or hair using a fixing device such as a clip. The infrared signal transmitted from the transmitter 80 is, for example, an 8-bit fixed pattern (nurse ID).

  FIG. 6 is a block diagram showing an electrical configuration of the passage sensor 18. With reference to FIG. 6, the passage sensor 18 includes a CPU 70, and a first light receiving module 72, a second light receiving module 74, a RAM 76, and a wireless LAN 78 are connected to the CPU 70. Each of the light receiving modules (72, 74, etc.) of each passing sensor 18 is assigned unique identification information (light receiving module ID). Each light receiving module (72, 74, etc.) detects an infrared signal (nurse ID) from the transmitter 80 (see FIG. 5). For example, when receiving the nurse ID, the light receiving module (72, 74) gives the received nurse ID to the CPU. The CPU 70 adds the light receiving module ID of the light receiving module (72, 74) that has received the nurse ID to the nurse ID and stores (temporarily stores) it in the RAM 76, and then, via the wireless LAN 78 and the network 14, Send to server 12.

  When the server 12 receives the nurse ID to which the light receiving module ID is added, the server 12 registers the location corresponding to the received light receiving module ID in the location DB 30 as the current location of the nurse indicated by the nurse ID. At this time, the server 12 refers to the clock circuit 12a and gives a time stamp to the information on the current position (place) of the nurse.

  FIG. 7 is a block diagram showing an electrical configuration of the repeater 20. Referring to FIG. 7, repeater 20 includes a CPU 90. Connected to the CPU 90 are a memory 92, an encoder 94, a non-contact sensor 98, an acceleration sensor 100, a wireless LAN 102, and the like. The memory 92 functions as a work memory or a buffer memory and is used by the CPU 90. A pin microphone 96 is connected to the encoder 94, and the encoder 94 modulates an audio signal input from the pin microphone 96 into compressed audio data such as MP3 (hereinafter simply referred to as “audio data”) and inputs the result to the CPU 90. In this way, the audio signal is compression-modulated in order to reduce the amount of use of the memory 92 and to reduce the amount of data transmitted via the wireless LAN 102. For example, the nurse inputs the contents of nursing work to be started or ended through voice through the pin microphone 96. Therefore, the server 12 can know the nursing work started or ended by the nurse by analyzing the voice.

  In FIG. 7, a plurality of acceleration sensors 100 a, 100 b, 100 c, and 100 d (see FIG. 5) are comprehensively shown as the acceleration sensor 100 for simplicity.

  Here, as can be seen with reference to FIG. 5, each nurse (each user) is equipped with the terminal 16 and the repeater 20 in addition to the transmitter 80 described above. The terminal 16 is worn on, for example, a nurse's wrist. Although detailed illustration is omitted, the wristwatch is worn so that the LCD 48 of the terminal 16 can be seen, and the wristwatch is worn using a fixing device such as a band.

  In the repeater 20, circuit components (see FIG. 7) other than the pin microphone 96, the non-contact sensor 98, and the acceleration sensor 100 (100a, 100b, 100c, 100d) are accommodated in a box (housing) 200. Is attached to the waist (belt portion) of the nurse.

  The pin microphone 96 is attached near the neck of the nurse's clothes (white coat). Further, the non-contact sensor 98 is housed in a pen-type case so as to be inserted into the breast pocket of the nurse's lab coat. However, in FIG. 5, a pen-shaped case is shown outside the breast pocket for easy understanding.

  Further, the acceleration sensor 100 is attached to the nurse's hands (both arms), chest and waist. In this embodiment, the acceleration sensor 100a is attached to the right arm, the acceleration sensor 100b is attached to the left arm, the acceleration sensor 100c is attached to the chest, and the acceleration sensor 100d is attached to the waist. However, in FIG. 5, each acceleration sensor 100 is described outside the lab coat for easy understanding, but each acceleration sensor 100 is actually used by using an appropriate fixing device such as a rubber band. It is fixed to the arm etc. inside the lab coat.

  Although not shown in FIG. 5, the non-contact sensor 98 and each acceleration sensor 100 are electrically connected to the CPU 90 in the box 200 using connection lines, and the pin microphone 96 is connected to the inside of the box 200 using connection lines. The encoder 94 is electrically connected. However, you may make it connect by short-distance radio | wireless like Bluetooth, without using a connection line. That is, it is only necessary to be electrically connected.

  The pin microphone 96 used in this embodiment has directivity. This is to protect the patient's privacy by detecting only the voice of the nurse wearing the pin microphone 96.

  Further, a pyroelectric sensor can be used as the non-contact sensor 98, and the CPU 90 turns on / off the pin microphone 96 in accordance with an input from the non-contact sensor 98. In this embodiment, when the nurse raises and lowers his / her hand twice in front of the non-contact sensor 98, that is, the pyroelectric sensor, the detection signal is input to the CPU 90. In response, the CPU 90 turns on the pin microphone 96, Thereafter, when the nurse raises and lowers his / her hand twice in front of the pyroelectric sensor, the pin microphone 96 is turned off. However, the CPU 90 is configured to turn off the pin microphone 96 even when a predetermined time (10 seconds) has elapsed without depending on the operation of the nurse.

  The acceleration sensor 100 is, for example, a multi-axis (3-axis) acceleration sensor, has a sampling frequency of 200 Hz, and can measure acceleration up to ± 3 G (G is gravity). In the repeater 20, acceleration data (acceleration data) detected by the acceleration sensor 100 is supplied to the CPU 90. The CPU 90 stores (temporarily stores) the acceleration data from the acceleration sensor 100 in the memory 92, and the acceleration data for the predetermined time is transmitted to the server via the wireless LAN 102 and the network 14 every predetermined time (for example, 10 seconds). 12 to send. As described above, since the work content recognition dictionary is stored in the knowledge DB 26, the dictionary data and the acceleration data (monitor information) transmitted from the repeater 20 are compared by a known DP matching method or the like. By doing so, it is possible to identify the contents of the nursing work being performed.

  It should be noted that another sensor such as a gyro sensor, an illuminance sensor, or a temperature sensor can be used instead of or in addition to the acceleration sensor 100. When another sensor is used, the output of the other sensor is transmitted to the server 12.

  The system 10 (server 12) having such a configuration includes reminder information stored in the schedule DB 32, monitor information from the repeater 20 and the monitor device 22 (in other words, information appropriately updated to the nursing situation DB 28, etc.), When the information to be presented to the nurse is detected from the input information entered by the nurse and the like, the nurse to be presented with the information is selected and presented.

  Information presented to nurses includes, for example, notifications of tasks (operations) that nurses should perform, notifications of notifications when nurses do the wrong procedure (including missing procedures), There are things that notify that the patient's condition has suddenly changed, and those that notify a call from another nurse.

  The nurse to be selected is determined according to the information to be presented. As will be described later, in this embodiment, the condition of the presentation destination is stored in advance in association with the information (message). A nurse who falls under is selected.

  When a nurse is selected, information is presented to the selected nurse. Specifically, the server 12 refers to the nursing situation DB 28 and recognizes the current working situation (work load) of the selected nurse. Then, the workload of the nurse is compared with the information content (urgency level), and it is determined whether information should be presented to the nurse at the present time. That is, it is determined whether or not the information can be presented to the nurse when the information to be presented occurs. Such a determination can be made based on the determination reference data stored in the knowledge DB 26.

  For example, when a nurse is taking care of a patient whose condition has suddenly changed, if information indicating that another patient's infusion has been completed occurs, it is determined that the information cannot be presented (information cannot be presented). Is done. In addition, for example, when information indicating that a meeting starts after 5 minutes occurs when an infusion is being performed on a patient, it is determined that information cannot be presented. In this way, when a nurse is working with a high degree of urgency, working with a work that does not allow mistakes, or busy, when information that is not so urgent is generated, If the nurse cannot respond to the information even if it is presented, it is determined that the information cannot be presented.

  Here, nurses have a lot of work to do, and the work often changes in a short time. That is, the state where information can be presented and the state where information cannot be presented often change in a short time. Therefore, in this embodiment, when information to be presented occurs, even if it is determined that the information cannot be presented to the selected nurse, it waits for a predetermined time, I try to see if the situation changes. During standby, information is presented when information can be presented to the nurse. For example, when it is detected that the nurse's business has been changed with reference to the nursing situation DB 28 during standby, whether or not information can be presented to the nurse at the time of the business change. It is good to judge again. Thus, the nurse can receive information at an appropriate timing, and can reliably present information to the nurse who should present the information. That is, information can be presented to the nurse when the nurse is ready for the information. In addition, the work load on the nurse may be reduced when the work is changed, so by re-determining whether the nurse can present information at that time, Judgment processing can be performed at an appropriate timing, and useless judgment processing can be reduced.

  Further, in this embodiment, even when waiting for a predetermined time, when information cannot be presented to the first selected nurse (first presentation destination) (an acknowledgment (Ack ) Is included), other nurses (second presentation destination) are selected to present information. Since nurses' work is characterized by the cooperation of multiple people, even if information cannot be presented to the main nurse who should present the information, information is presented to other nurses. By doing so, instructions (business) included in the information are surely executed by other nurses. That is, information can be transmitted more reliably. In the same way as the first presentation destination, it is determined whether information can be presented to the selected nurse as well as the second presentation destination. You may wait and see if the status of the nurse changes during the wait. However, as a second presentation destination, a nurse with a space may be selected in advance, and information presentation may be executed as it is.

  Further, in this embodiment, the notification method is changed in accordance with the nurse's situation (including the surrounding situation), and the nurse is notified that information is presented by the optimum notification method. For example, in the vicinity of a hospital room at night, instead of notifying with sound from the speaker 58 of the terminal 16, the fact that the terminal 16 is vibrated by the vibration motor 52 is notified that information is being presented. In a situation (place) where there is no restriction on the notification method, it is preferable to notify that there is information presentation by a notification method set according to each nurse's preference. Some nurses are more likely to recognize auditory notifications such as voice, others are easier to recognize tactile notifications such as vibration, and visual notifications such as blinking light. This is because some are easier to recognize. Thus, it is possible to notify the nurse that there is information presentation more reliably, and the information presentation can be executed reliably.

  Further, in this embodiment, when information cannot be presented to both the first presentation destination and the second presentation destination (including the case where there is no positive response (Ack) from the nurse even when the information is presented). In this case, information is presented on a monitor installed in the nurse station. Normally, all nurses stop by the nurse station during their working hours, so that information that has not been presented is reliably confirmed. Then, the main nurse (first presentation destination) who should present the information, or the nurse in hand, can perform the work reliably. However, when information cannot be presented to the second presentation destination, the presentation destination 3, the presentation destination 4, and other nurses may be selected as appropriate. In addition, if there is work to be performed that could not be performed during working hours (within the shift), instead of presenting the information on the monitor installed at the nurse station or presenting it, the person responsible for the next shift (leader) ) May be presented with information. For example, when a nurse says that there is a story and a nurse is busy at that time, if the nurse responds that “later”, it is often forgotten in the nursing setting. is there. Even in such a case, if the person in charge is presented with information indicating that the patient's request is not met at the next shift, the patient can be surely visited.

  More specific description will be given below. As described above, the advice DB 34 connected to the server 12 stores information related to the presentation information presented to the nurse for each information. For example, as shown in FIG. 8, the first presentation destination, the first trial time, the second presentation destination, the second trial time, the completion condition, the message content, and the emergency are associated with the identification information (information ID) of the information. The degree is memorized. In the column of the first presentation destination, conditions for searching (selecting) the first presentation destination are described. Here, the first presentation destination refers to the main nurse to whom the information is to be presented. In this embodiment, a specific one who has performed nursing work as the basis of the information is selected. In the first trial time column, a time to try to present information to the first presentation destination is described. In the second presentation destination field, conditions for searching (selecting) the second presentation destination are described. Here, the second presentation destination refers to a nurse who transfers information when information cannot be presented to the first presentation destination or when there is no affirmative response even when information is presented. In this case, a plurality of people who mainly meet the conditions are selected. In the second trial time column, a time to try to present information to the second presentation destination is described.

  In the completion condition column, a condition for determining that the information presentation has been completed is described. In this embodiment, the same completion condition is set for the first presentation destination and the second presentation destination, but different completion conditions are set for the first presentation destination and the second presentation destination. You can also. In the message content column, data (text data, document file, etc.) for indicating the specific content of information presentation in characters is described. In the urgent level column, the urgency level of this information is described in a plurality of stages (in this embodiment, three levels of high, medium, and low).

  For example, in the example of FIG. 8, the information whose information ID is m1 indicates that the drip of the patient A in the room x is finished. In this case, the condition of the first presentation destination that conveys the information is the nurse who performed the infusion, the first trial time is 3 minutes, and the condition of the second presentation destination is near the infusion patient A. It is a nurse and the second trial time is found to be 1 minute. The information completion condition is when the information is presented to the first presentation destination or the second presentation destination and the acknowledgment (Ack) is confirmed. Further, a message such as “Room x, Infusion patient A, Infusion end time” is presented as the message content, and it can be seen that the urgency of the information is “medium”. Note that the message content is only an example. For example, if the room where the infusion patient is located and the nurse's current position are separated, the time until the nurse reaches the room where the infusion patient is present is taken into account. Then, a message is appropriately created, such as “Room x, Infusion patient A, 10 minutes before the end of infusion”.

  In addition, the information whose information ID is m2 is to transmit a warning when an abnormality is detected from the heart rate measuring device of the patient B in the y room. In this case, the condition of the first presentation destination for transmitting the information is the nurse in charge of the patient B, the first trial time is 10 seconds, and the condition of the second presentation destination is three persons from the vicinity of the patient B. It is understood that the second trial time is 10 minutes. The information completion condition is when the information is presented to the first presentation destination or the second presentation destination and the acknowledgment (Ack) is confirmed. Furthermore, a sentence such as “Warning from room y, patient B, heart rate measuring device” is presented as the message content, and it can be seen that the urgency of the information is “high”. However, as in this example, in the case of information that is related to the patient's life and without any delay, the information presentation to the first presentation destination is omitted and the information presentation to the second presentation destination is omitted. It may be executed immediately. In this example, the second trial time is 10 minutes, but the second trial time is unlimited until the acknowledgment from the nurse is confirmed, so that information can be communicated to someone without fail. Good.

  9 and 10 show examples of the information presentation screen 210 displayed on the LCD 48 by the terminal 16 that has received the information from the server 12. The information presentation screen 210 disappears after each trial time.

  Referring to FIG. 9, information presentation screen 210 includes message content 212, urgency 214, unread display 216, reception time 218, unread message count 220, unprocessed message count 222, unprocessed display 224, and confirmation button 226. Etc. are displayed as appropriate. The message content 212 displays the content of information in characters (symbols or pictures may be used), and the urgency 214 indicates the urgency of the currently displayed information. The unread display 216 indicates that the currently displayed information is in an unread state, that is, information in which the confirmation button 226 has not been selected by the nurse (the information has not been confirmed). The reception time 218 indicates the time (date and time) when the displayed information is received.

  The number of unread messages 220 indicates the number of information that has been unread and whose trial time has passed. The number of unprocessed messages 222 indicates the number of information that has not been accepted (acknowledged) by anyone selecting the confirmation button 226. That is, when the confirmation button 226 (for example, an OK button) indicating an affirmative response is selected by the nurse, the information is processed. In addition, for example, when information is presented to more nurses than the number of nurses actually required for work, if the number of nurses actually required for work is positively acknowledged, the information The information is processed in all the nurses' screens that present The unprocessed display 224 clearly indicates the urgency level of the unprocessed message by color (color). In FIG. 9, although the color is omitted, for example, information with high urgency is shown in red, information with medium urgency is shown in yellow, and information with low urgency is shown in blue. The process display 224 is color-coded according to the urgency of information. The unprocessed display 224 increases according to the number of unprocessed messages. For example, when there are two unprocessed messages, the two unprocessed displays 224 are color-coded according to the urgency of each information. Is displayed. This allows the nurse to easily recognize what level of urgency information remains unprocessed.

  The confirmation button 226 is a button for inputting a response (confirmation) to the information presented by the nurse. The confirmation button 226 is appropriately provided according to the information to be presented. As shown in FIG. 9, in the case of information notifying the end of infusion, for example, an OK button displayed as “OK” is provided. For example, when the OK button is selected by the operation of the key switch 44 of the terminal 16 by the nurse, a signal indicating that there is an acknowledgment (Ack) from the nurse is given from the terminal 16 to the server 12. On the other hand, when the trial time of the information passes without the OK button being selected, the server 12 determines that there is no acknowledgment.

  Also, as shown in Fig. 10, in the case of information that conveys a request for help from a busy nurse, "I will go immediately", "I will go within 5 minutes", "I can't take my hands off" A displayed confirmation button 226 is provided. For example, when the confirmation button 226 displayed as “I will go immediately” or “I will go within 5 minutes” is selected by the operation of the key switch 44 of the terminal 16 by the nurse, an affirmative response ( A signal is sent from the terminal 16 to the server 12 that there is an Ack). On the other hand, if the confirmation button 226 displayed as “cannot be released” is selected, or if the trial time of the information has passed without any confirmation button 226 being selected, the server 12 determines that there is no acknowledgment. Will be. Since the display other than the confirmation button 226 on the information presentation screen 210 shown in FIG. 10 is the same as that shown in FIG. 9, the description thereof is omitted.

  Below, an example of operation | movement of the above systems 10 is demonstrated according to a flowchart. Specifically, the server 12 shown in FIGS. 1 and 2 executes the entire process according to the flowchart shown in FIG. Referring to FIG. 11, when the operation starts, server 12 determines whether there is information to be presented in step S <b> 1. For example, referring to the reminder information described in the schedule DB 32, it is determined whether there is a nursing task whose start time is approaching, or the work procedure is determined based on the monitor information from the repeater 20, the monitor device 22, and the like. It is determined whether there is information to be presented by determining whether there is an erroneous nurse or whether there is a patient whose condition has suddenly changed. The determination in step S1 is repeated at regular intervals. Below, as a specific example, the case where the information that it is the infusion end time of the patient A is presented will be described.

  If “YES” in the step S1, that is, if information to be presented to the nurse is generated, the process proceeds to a step S3. In step S3, a first presentation destination of information is searched. That is, referring to the advice DB 34, a nurse is searched from the conditions described in the first presentation destination. In this embodiment, since the specific person (person in charge) who performed the nursing work that is the basis of the information is selected as the first presentation destination, the patient A is referred to the schedule DB 32 and the like. Select the nurse who instilled.

  In subsequent step S5, an information presentation trial process described later is executed on the nurse (first presentation destination) selected in step S3. In short, the information presentation trial process is a process for determining whether or not the completion condition is satisfied within the trial time. In this embodiment, the trial time and the completion condition are determined with reference to the advice DB 34.

  In a succeeding step S7, it is determined whether or not a completion condition is satisfied for the first presentation destination. If “YES” in the step S7, that is, if it is determined that the completion condition is satisfied in the information presentation trial process in the step S5, it is determined that the information is surely transmitted to the first presentation destination, and the entire process regarding the information is performed. Ends as is. On the other hand, if “NO” in the step S7, that is, if it is determined that the completion condition is not satisfied in the information presentation trial process in the step S5, the process proceeds to the step S9.

  In step S9, a second presentation destination of information is searched. Specifically, the nurse is searched from the condition described in the second presentation destination with reference to the advice DB 34. The nurse search in this case may be performed by a DB inquiry using SQL or the like for the nursing situation DB 28 and the place DB 30. In this system 10, the nurse's situation (including the work situation and the current position) is recorded in the nursing situation DB 28 and the place DB 30, and the record is updated as appropriate. Therefore, the second presentation destination is designated by the DB inquiry. Thus, a more flexible search can be performed. In this case, the nurse near the patient A is searched by the SQL sentence.

  In subsequent step S11, information presentation trial processing is executed for the nurse (second presentation destination) selected in step S9. The information presentation trial process in step S11 is the same as the information presentation trial process in step S5 except that the first presentation destination and the first trial time are the second presentation destination and the second trial time, respectively. Since there is, explanation is omitted.

  In a succeeding step S13, it is determined whether or not a completion condition is satisfied for the second presentation destination. If “YES” in the step S13, that is, if it is determined that the completion condition is satisfied in the information presentation trial process in the step S11, it is determined that the information is surely transmitted to the second presentation destination, and the entire process related to the information is performed. Ends as is. On the other hand, if “NO” in the step S13, that is, if it is determined that the completion condition is not satisfied in the information presentation trial process in the step S11, the process proceeds to the step S15.

  In step S15, information is presented on the monitor. Specifically, a signal is transmitted to the monitor installed in the nurse station, and information is presented on the monitor. Then, the whole process regarding the information is terminated.

  FIG. 12 is a flowchart showing the information presentation trial process in step S5 shown in FIG. As shown in FIG. 12, when the server 12 starts the information presentation trial process, the server 12 acquires the latest work status of the first presentation destination in step S21. That is, referring to the nursing situation DB 28, the current workload and busy identification results of the first presentation destination are acquired.

  In a succeeding step S23, it is determined whether or not information can be presented. That is, the work status of the first presentation destination acquired in step S21 is compared with the urgency of the information to be presented, and it is determined whether or not the information can be presented to the first presentation destination. This determination is made by collating with the determination reference data stored in the knowledge DB 26.

  If “NO” in the step S23, that is, if it is determined that the information cannot be presented to the first presentation destination, the process proceeds to the step S25, and has the first trial time (for example, 3 minutes) passed? Judge whether or not. If “YES” in the step S25, that is, if the first trial time has passed without providing information, the process proceeds to a step S39 to determine that the completion condition is not satisfied, and to return to the entire process shown in FIG. To do.

  On the other hand, if “NO” in the step S25, that is, if the first trial time has not elapsed, the process waits for a predetermined time in the step S27 and determines whether or not the business of the first presentation destination has been changed in a step S29. To do. That is, during standby, the nursing status DB 28 is referred to and it is determined whether or not the status of the first presentation destination updated at any time has changed. If “YES” in the step S29, that is, if there is a change in the business of the first presentation destination, the process returns to the step S23 to retry the determination as to whether or not information can be presented to the first presentation destination. . On the other hand, if “NO” in the step S29, that is, if there is no change in the business of the first presentation destination, the process returns to the step S25.

  If “YES” in the step S23, that is, if it is determined that the information cannot be presented to the first presentation destination, the process proceeds to a step S31. In step S31, an information notification method is determined. Specifically, for example, considering the surrounding situation of the first presentation destination, it is determined whether there is a restriction on the notification method. If there is a restriction, the permitted notification method is selected. If there is no restriction, for example, a favorite notification method of the first presentation destination or a preset notification method is selected.

  In subsequent step S33, information is presented to the first presentation destination. Specifically, it is notified that there is information presentation by the notification method determined in step S31, and the information presentation screen 210 as shown in FIG. 9 is displayed on the LCD 48 of the terminal 16.

  In step S35, it is determined whether or not there is an affirmative response (Ack) from the first presentation destination. For example, it is determined whether or not a signal indicating that the confirmation button 226 (that is, the OK button) on the information presentation screen 210 has been selected by the user is received from the terminal 16. If “NO” in the step S35, that is, if there is no affirmative response from the first presentation destination, the process proceeds to a step S37 to determine whether or not the first trial time has elapsed. If “YES” in the step S37, that is, if the first trial time has passed without any acknowledgment from the first presentation destination even if information is presented to the first presentation destination, the process proceeds to the step S39 and is completed. It is determined that the condition is not satisfied, and the process returns to the entire process shown in FIG. On the other hand, if “NO” in the step S37, that is, if the first trial time has not elapsed, the process returns to the step S35.

  If “YES” in the step S35, that is, if there is an affirmative response from the first presentation destination, the process proceeds to a step S41, it is determined that the completion condition is satisfied, and the process returns to the entire process shown in FIG. To do.

  According to this embodiment, even when it is determined that information to be presented to the user (nurse) cannot be presented at the time when the information to be presented is generated, information is provided to the user by waiting for a predetermined time. To see if it ’s in a state where it can be presented. Since the information is presented when the information can be presented (that is, the timing is measured), the information can be presented at an appropriate timing for the user, and the information can be transmitted reliably.

  If information cannot be presented to the main user (first presentation destination) who should present information after waiting for a predetermined time, information is presented to another user (second presentation destination). Therefore, information can be transmitted more reliably.

  In the above-described embodiment, the system 10 is applied to a hospital and information is presented to a nurse who performs nursing work. However, the present invention is not limited to this. For example, the information can be presented to a doctor or a caregiver, or the information can be presented to a worker working there by applying to a general company or factory.

  In the above-described embodiment, information is presented by the portable terminal 16 such as PHS. However, the present invention is not limited to this, and is fixed to the environment (for example, a plurality of appropriate places where the user mainly performs business) Information may be presented by a monitor or the like installed in the computer.

  In the above-described embodiment, a specific one person is selected as the first presentation destination. However, the present invention is not limited to this, and a plurality of persons may be selected. Similarly, a specific one person may be selected as the second presentation destination, or a plurality of persons may be selected.
