The physiological information detection unit 3 is a part that detects physiological information such as the number of blinks of the user and the heart rate. The physiological information detection unit 3 outputs various detected physiological information to the sleep control unit 2.

  The sleep control unit 2 is connected to an alarm receiving unit 4 that receives an alarm (warning). The alarm receiving unit 4 is a part that receives an alarm notifying an emergency from an emergency center or the like that receives the 119th report by performing communication control with the outside. The alarm received by the alarm receiver 4 includes a variety of information. For example, the emergency transport alarm notified to the sleep control device 1 installed in an emergency hospital includes the patient status and the current ambulance status. Includes location. The alarm receiving unit 4 outputs the received information to the sleep control unit 2.

  In addition, a stimulus imparting device 5 is connected to the sleep control unit 2. The stimulus imparting device 5 is a device that imparts a physical stimulus to the user. Examples of the stimulus imparting device 5 include a speaker that imparts an auditory stimulus by sound, and a light emitting unit that imparts a visual stimulus by light. Examples of the stimulus given to the user by the stimulus applying device 5 include an arousal stimulus, a maintenance stimulus, and a wakefulness stimulus. Examples of the awakening stimulus include a visual stimulus such as flash light from a light emitting device, and an auditory stimulus such as music reproduction at a sound pressure exceeding a sensory threshold (for example, about 60 to 80 dB with white noise). Examples of the arousal stimulus include a perceptual stimulus such as room temperature adjustment suitable for sleep, a tactile stimulus by massage, and an auditory stimulus such as music reproduction suitable for sleep. Examples of the maintenance stimulus include continuous application of faint light and faint vibration, and auditory stimulus that repeatedly reproduces a sound of a predetermined sound pressure level (for example, about 55 dB for pink noise) for a period of 30 seconds.

  The sleep control unit 2 is a device that provides and controls a sleep pattern corresponding to the sleepiness level to the user and awakens the user when receiving an alarm. The sleep control unit 2 includes a sleepiness level detection unit 6, a sleep depth determination unit 7, a sleep pattern selection unit 8, a sleep depth comparison unit 9, a sleep pattern application stimulus control unit 10, and an emergency application stimulus control unit 11. It is equipped with.

  The sleepiness level detection unit 6 is a part that detects the current sleepiness level of the user based on various physiological information detected by the physiological information detection unit 3. The sleepiness level detection unit 6 detects the sleepiness level according to the number of blinks and the heart rate of the physiological information detected by the physiological information detection unit 3, and outputs the detected sleepiness level to the sleep pattern selection unit 8. As shown in FIG. 2, the sleepiness level is classified into six levels 1 to 6 from mild to severe according to the severity of sleepiness. In this embodiment, the sleepiness degree 1-2 is defined as extremely mild sleepiness, the sleepiness degree 3-5 is defined as mild sleepiness, and the sleepiness degree 6 is defined as severe sleepiness that requires recovery from fatigue.

  The sleep depth determination unit 7 is a part that determines the sleep depth of the user during sleep (hereinafter referred to as “current sleep depth”). The sleep depth determination unit 7 determines the current sleep depth of the user based on the heart rate detected by the physiological information detection unit 3. The sleep depth determination unit 7 outputs the determined current sleep depth to the sleep depth comparison unit 9.

  The sleep pattern selection unit 8 is a part that selects one sleep pattern corresponding to the sleepiness level detected by the sleepiness level detection unit 6 and sets it as a sleep method to be controlled. Information about the sleep pattern selected and set by the sleep pattern selection unit 8 is output to the sleep depth comparison unit 9 and the sleep pattern application stimulus control unit 10.

  The sleep pattern selected and set by the sleep pattern selection unit 8 includes a plurality of sleep patterns P1 to P4 corresponding to the sleepiness level. As shown in FIG. 2, the sleep patterns P1 to P4 correspond to sleep patterns P1 to P3 corresponding to sleepiness levels 3 to 5 which are mild sleepiness and sleep patterns P4 corresponding to sleepiness level 6 which is severe sleepiness. And classified.

  The sleep patterns P1 to P3 are sleep patterns in which the user's sleep depth is maintained for a certain period of time at a sleep depth 2, which is a shallow sleep that allows the user to sleep. That is, as shown in FIG. 2, the sleep pattern P1 is a sleep pattern corresponding to the sleepiness degree 3, and the sleep maintenance time T1 maintained at the sleep depth 2 is, for example, about 5 minutes. The sleep pattern P2 is a sleep pattern corresponding to the sleepiness level 4, and the sleep maintenance time T2 maintained at the sleep depth 2 is, for example, about 10 minutes. The sleep pattern P3 is a sleep pattern corresponding to sleepiness level 5, and the sleep maintenance time T3 maintained at the sleep depth 2 is, for example, about 30 minutes.

  On the other hand, the sleep pattern P4 is a sleep pattern using a natural sleep rhythm. As shown in FIG. 2, in the sleep pattern P <b> 4, the sleep depth of the user is increased to the sleep depth 4 using a natural sleep rhythm, and is temporarily maintained at the sleep depth 4. Then, after being maintained at the sleep depth 4, the user is awakened when the sleep becomes shallow until the sleep depth 2. In addition, in the nap in an emergency organization, since it is necessary to respond quickly to an emergency situation, it is preferable to select the sleep patterns P1 to P3 without selecting the sleep pattern P4.

  The sleep depth comparison unit 9 compares the sleep depth (hereinafter referred to as “target sleep depth”) in the sleep pattern selected and set by the sleep pattern selection unit 8 with the current sleep depth determined by the sleep depth determination unit 7. And it is a part which outputs the comparison signal about the difference to the sleep pattern provision stimulation control part 10. FIG.

  The sleep pattern imparting stimulus control unit 10 is a part that drives and controls the stimulus imparting device 5.

  When the comparison signal from the sleep depth comparison unit 9 is input, the sleep pattern application stimulus control unit 10 provides the user with any one of the awakening stimulus, the maintenance stimulus, and the wakefulness stimulus according to the comparison signal. The drive of the stimulus applying device 5 is controlled. That is, when the sleep pattern imparting stimulus control unit 10 receives a comparison signal from the sleep depth comparison unit 9 that the current sleep depth is greater than the target sleep depth, that is, the sleep that is targeted by the user's sleep depth When it is deeper than the depth of the device, the stimulating device 5 is operated to give the user a wake-up stimulus that reduces the sleep depth of the user. When the sleep pattern imparting stimulus control unit 10 receives a comparison signal from the sleep depth comparison unit 9 that the current sleep depth is smaller than the target sleep depth, that is, the sleep depth of the user is the target. When it is shallower than the depth of sleep, the stimulating device 5 is operated to give the user a wakefulness stimulus that increases the sleep depth of the user. The sleep pattern imparting stimulus control unit 10 receives a comparison signal from the sleep depth comparison unit 9 that the current sleep depth and the target sleep depth are the same, that is, the sleep depth of the user is the target. When the sleep depth is equal to the sleep depth, the stimulus applying device 5 is operated to apply a maintenance stimulus for maintaining the user's sleep depth to the user.

  On the other hand, when the sleep pattern selected and set by the sleep pattern selection unit 8 is completed, the sleep pattern imparting stimulus control unit 10 drives and controls the stimulus imparting device 5 so as to impart the arousal stimulus to the user. That is, when the sleep pattern P1 to P3 is selected and set by the sleep pattern selection unit 8, the sleep pattern imparting stimulus control unit 10 has elapsed time after starting the sleep pattern exceeds the sleep maintenance time of the sleep pattern. Then, the stimulus imparting device 5 is driven and controlled so as to impart an arousal stimulus to the user, and the user is awakened. In addition, when the sleep pattern application stimulus control unit 10 determines that the sleep pattern P4 is selected and set by the sleep pattern selection unit 8 and the sleep depth determination unit 7 determines that the user's sleep has become shallower to the sleep depth 2, the awakening stimulus The stimulus applying device 5 is driven and controlled so as to give the user awaken the user.

  The emergency giving stimulus control unit 11 is a part that drives and controls the stimulus applying device 5 so as to give an awakening stimulus to the user when the alarm receiving unit 4 receives the warning. If the emergency receiving stimulus control unit 11 needs to take an emergency response as soon as an alarm is notified, such as a fire department, the alert receiving unit 4 receives the alert immediately after receiving the alarm. The stimulus applying device 5 can be driven and controlled so as to be applied to the device, and a predetermined holding time (predetermined time) elapses when an emergency response is not always required even when an alarm is notified, such as an emergency hospital. Later, it is possible to drive and control the stimulating device 5 so as to apply a wake-up stimulus to the user.

  The predetermined holding time can be calculated based on the distance between the place where the alarm is transmitted and the place where the alarm is received. Consider a case where a doctor takes a nap using the sleep control device 1 in an emergency hospital. In this case, the doctor cannot treat the emergency patient at the emergency hospital until the emergency vehicle arrives at the emergency hospital. Therefore, the emergency vehicle arrives at the emergency hospital based on the distance between the location where the alarm was transmitted (the position of the emergency patient or emergency vehicle) and the location where the alarm was received (the emergency hospital using the sleep control device 1). The estimated time of arrival is estimated, and this estimated arrival time is set as a predetermined hold time.

  In this case, if the alarm received by the alarm receiver 4 includes information on the location where the alarm is transmitted, the information on the location where the alarm is transmitted can be acquired from the information included in the alarm. On the other hand, when the alarm received by the alarm receiving unit 4 does not include the information on the place where the alarm is transmitted, the information on the place where the alarm is transmitted can be acquired by the operation of the operator or the like.

  Further, the predetermined hold time can be calculated based on the time required for preparation of work after the user awakens. Consider a case where a doctor takes a nap using the sleep control device 1 in an emergency hospital. In this case, when the emergency vehicle arrives at the emergency hospital, it is preferable that the preparation for the medical action is completed, but a predetermined time is required for the preparation for the medical action. Therefore, by calculating the time required for preparation for medical practice, the preparation start time for medical practice is calculated from the scheduled time when the ambulance arrives at the emergency hospital, and from the time when the alarm is received to the preparation start time for medical practice. Time is defined as a predetermined holding time. In addition, medical content varies depending on the patient's condition, and the time required for preparation of medical practice varies depending on the medical content, so the relationship between the patient's state and medical content, the relationship between the medical content and time required for preparation, etc. It is preferable to obtain a database based on experiments and landscapes.

  In this case, when information such as the patient's condition is included in the alarm received by the alarm receiver 4, information regarding the patient's condition is acquired from the information included in the alarm, and the acquired information is stored in the database. By comparing, the time required to prepare for medical practice can be obtained. On the other hand, if the alarm received by the alarm receiver 4 does not include information such as the patient's condition, the time required for preparation for medical practice can be set by the operator's operation.

  Further, the predetermined hold time can be calculated based on the time required for the user to get up after receiving a wake-up stimulus. Consider a case where a doctor takes a nap using the sleep control device 1 in an emergency hospital. In this case, it is necessary that the doctor who performs the medical action is completely up when the emergency vehicle arrives at the emergency hospital. Therefore, by calculating backwards the time required for the user to get up after receiving a wake-up stimulus, the time for giving the wake-up stimulus to the doctor is calculated from the scheduled time when the ambulance arrives at the emergency hospital, and the alarm is issued. The time from the time of receiving “a” to the awakening stimulus application time is defined as a predetermined holding time. Since the time required for a user to get up after receiving a wake-up stimulus varies depending on the user's constitution, the time required to wake up after receiving a wake-up stimulus is determined for each user based on experiments and experiences. It is preferable to obtain a database.

  As described above, according to the sleep control device 1 according to the present embodiment, the user's sleep depth can be controlled. Therefore, for the user who takes a nap, the user is maintained by keeping a shallow sleep. It is possible to appropriately eliminate drowsiness and to suppress a decrease in response after awakening.

  Moreover, according to the sleep control device 1 according to the present embodiment, the sleep control device 1 can be awakened when an alarm is received even while the user is sleeping by controlling the sleep depth. It is possible to respond appropriately to emergencies that occur while using the device.

  Furthermore, when an alarm is received, an awakening stimulus is applied after a predetermined holding time has elapsed, so that an appropriate awakening time according to the user's constitution can be secured and more sleep maintenance time can be secured.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the sleep control device has been described as selecting and setting from the sleep patterns P1 to P4 to control the sleep depth of the user. However, the sleep pattern that is maintained only at the sleep depth 2 that is a shallow sleep. It is good also as what controls a user's sleep depth using only.

  Moreover, as shown in FIG. 3, you may provide the counter 12 in the sleep control apparatus 1 in order to count predetermined holding time. When the alarm receiving unit 4 receives an alarm, the counter 12 counts the predetermined holding time calculated by the emergency giving stimulus control unit 11, and the emergency giving stimulus control unit 11 has the counter 12 set the predetermined holding time. When the counting is finished, the stimulus imparting device 5 is driven and controlled so as to impart the arousal stimulus to the user.

  Moreover, the sleep control apparatus 1 may be equipped with the database which stores predetermined hold time. Thereby, the predetermined holding time can be calculated appropriately.
