A device having a control unit for cooling and heating a user's body is known (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 2006-102020

  However, as there are hot and cold people, there is a difference in how the temperature is felt even at the same temperature. In conventional systems, the adjusted body temperature is a comfortable temperature for the user. There is a problem that it is not always.

  Then, an object of this invention is to provide the body temperature control system which can adjust a user's body temperature to the temperature comfortable for a user.

  The body temperature regulation system of the present invention executes an autonomic nerve state measuring unit that measures a dominant state of a sympathetic nerve and a parasympathetic nerve among user's autonomic nerves, and performs at least one of heating and cooling operations on the user A body temperature adjustment operation unit, and a control unit that causes the body temperature adjustment operation unit to execute the operation when the sympathetic nerve is measured to be dominant by the autonomic nerve state measurement unit. .

  When humans feel hot or cold, sympathetic nerves are dominant among autonomic nerves due to stress. The inventor of the present application has invented a body temperature regulation system that can cope with different ways of feeling the temperature by paying attention to this phenomenon. In other words, the body temperature regulation system of the present invention does not execute the operation for regulating the body temperature of the user based only on the objective criterion of temperature as in the prior art, but depends on the user that the sympathetic nerve is dominant. Since it is executed according to the standard, the user's body temperature can be adjusted to a temperature comfortable for the user.

  In addition, the body temperature regulation operation unit of the body temperature regulation system of the present invention is capable of executing both warming and cooling operations for the user, and the control unit warms and cools the user. After allowing the body temperature adjustment operation unit to perform one of the cooling operations, when the sympathetic nerve continues to be measured by the autonomic nerve state measurement unit for a predetermined time, it is added to the user. It is preferable to cause the body temperature adjusting operation unit to execute the other operation of temperature and cooling.

  If the user's sympathetic nerve continues to dominate for a predetermined time even if one of the heating and cooling operations is performed on the user, for example, the user may feel that it is hot. There is a possibility that it was warmed or cooled even though the user felt it was cold. In such a case, the body temperature regulation system of the present invention switches between the heating operation for the user and the cooling operation for the user, so that the body temperature of the user is adjusted to a temperature more comfortable for the user. Can do.

  The body temperature regulation system of the present invention includes a body temperature measurement unit that measures the body temperature of the user, and the control unit is measured by the autonomic nerve state measurement unit that the sympathetic nerve is dominant. In addition, it is preferable that the body temperature adjustment operation unit performs the operation based on the body temperature measured by the body temperature measurement unit.

  It can be estimated based on the user's body temperature whether the user's sympathetic nerve is dominant because the user feels hot or whether the user's sympathetic nerve is dominant because the user feels cold. it can. For example, when the user's body temperature is rising and the user's sympathetic nerve is dominant, it can be estimated that the user feels hot. The body temperature regulation system of the present invention performs the operation for regulating the user's body temperature based on not only the sympathetic dominant state but also the body temperature of the user, so that the body temperature of the user is further improved for the user. Can be adjusted to a comfortable temperature.

  In addition, the body temperature regulation system of the present invention includes a sweating state measurement unit that measures the sweating state of the user, and the control unit is measured by the autonomic nerve state measurement unit that the sympathetic nerve is dominant. It is preferable to cause the body temperature adjustment operation unit to execute the operation based on the sweating state measured by the sweating state measurement unit.

  Estimate whether the user's sympathetic nerve was dominant because the user felt hot, or whether the user's sympathetic nerve was dominant because the user felt cold based on the user's sweating state Can do. For example, when the user is sweating and the user's sympathetic nerve is dominant, it can be estimated that the user feels hot. The body temperature regulation system of the present invention performs the operation for regulating the body temperature of the user based on not only the dominant state of the sympathetic nerve but also the sweating state of the user. Furthermore, it can be adjusted to a comfortable temperature.

  In addition, the body temperature regulation system of the present invention includes a movement measurement unit that measures the movement of the user, and the body temperature adjustment operation unit can execute a cooling operation on the user, and the control When the movement measuring unit measures that the user is lying down and stops, the autonomic nerve state measuring unit determines that the sympathetic nerve is dominant. On the other hand, it is preferable to cause the body temperature adjusting operation unit to perform a cooling operation.

  It is known that when a human enters sleep, the body temperature is released to lower the deep body temperature. For this reason, humans can easily sleep by being slightly cooled from the outside, and can take good sleep. The thermoregulatory system of the present invention determines that the user is going to sleep because the user is lying down and is sympathetic among the user's autonomic nerves when the user is going to sleep. When the nerve is dominant, that is, when the user is not relaxed, a cooling operation is performed on the user. Therefore, the body temperature regulation system of the present invention can guide the user to sleep by adjusting the body temperature of the user who is going to sleep to a temperature comfortable for the user.

  Moreover, it is preferable that the body temperature regulation system of this invention is portable by the said user.

  With this configuration, the body temperature regulation system of the present invention can regulate the user's body temperature to a temperature comfortable for the user even when the user moves.

  The body temperature regulation system of the present invention can regulate a user's body temperature to a temperature comfortable for the user.

It has. The neck cooling / warming portion 31 is formed in a substantially U shape so as to be attached to the neck 92 of the user 90, and a plurality of U-shaped portions 31b having a surface 31a on the inner side and a plurality of outer surfaces on the U-shaped portion 31b. And a Peltier element 31c, which is a square block attached individually. In addition, the main body device 30 includes a tube 32 that is closely attached to a surface of the Peltier element 31c of the neck cooling / warming portion 31 opposite to the U-shaped portion 31b and circulates water therein, and a neck The power supply cable 33 connected to the Peltier element 31c of the partial cooling / warming part 31, the casing 34 connected to the tube 32 and the cable 33, the power supply cable 35 connected to the casing 34, and the cable And a housing 36 to which 35 is connected.

The Peltier element 31c is arranged in the neck cooling / warming part 31 so that one of the surface in contact with the U-shaped portion 31b and the surface in contact with the tube 32 generates heat and the other absorbs heat. When the surface of the Peltier element 31c that contacts the U-shaped portion 31b generates heat, the U-shaped portion 31b transmits the heat generated by the Peltier element 31c to the entire circumference of the neck portion 92 of the user 90, whereby the user 90 It is designed to perform heating. Further, when the surface of the Peltier element 31c that contacts the U-shaped portion 31b absorbs heat, the U-shaped portion 31b transmits the heat of the entire circumference of the neck portion 92 of the user 90 to the Peltier element 31c, whereby the user 90 Cooling is to be performed. The housing 34 and the housing 36 are attached to a belt 93 (see FIG. 1) worn by the user 90. A radiator (not shown) for cooling the water inside the tube 32 is accommodated in the housing 34.

  FIG. 5 is a block diagram illustrating a configuration of the main body device 30.

  As shown in FIG. 5, the main body device 30 includes the above-described Peltier element 31c constituting a neck cooling / heating unit 31 (see FIG. 4), a fan 34a for cooling the above-described radiator, and a tube 32 (see FIG. 4). ), A control unit 36a for controlling the entire apparatus, a storage unit 36b storing a program executed by the control unit 36a, and the sensor device 20 (FIG. 1). (See FIG. 3). The receiving unit 36c wirelessly receives the data transmitted by the transmitting unit 22d (see FIG. 3). The fan 34a and the pump 34b are accommodated in the housing 34 (see FIG. 4). The control unit 36a is configured by a CPU or the like. The storage unit 36b is configured by a ROM or the like.

  In addition, when the temperature of the inner surface 31a of the neck cooling / warming portion 31 is lowered by the Peltier element 31c, the temperature of the surface in contact with the tube 32 of the Peltier element 31c increases. Here, the controller 36a supplies voltage to the fan 34a and the pump 34b when the temperature of the inner surface 31a of the neck cooling / heating unit 31 is lowered. Accordingly, the water inside the tube 32 is circulated by the pump 34b between the surface of the Peltier element 31c that contacts the tube 32 and the above-described radiator. As a result, the heat generated on the surface of the Peltier element 31c that contacts the tube 32 is absorbed by the water inside the tube 32 from the surface of the Peltier element 31c that contacts the tube 32, and then the radiator from the water inside the tube 32 The air is discharged to the outside air by the fan 34a.

  Further, when the temperature of the inner surface 31a of the neck cooling / warming portion 31 is raised by the Peltier element 31c, the temperature of the surface in contact with the tube 32 of the Peltier element 31c is lowered. Here, when the temperature of the inner surface 31a of the neck cooling / heating unit 31 is raised, the control unit 36a supplies a voltage to the fan 34a and the pump 34b. Accordingly, the water inside the tube 32 is circulated by the pump 34b between the surface of the Peltier element 31c that contacts the tube 32 and the above-described radiator. As a result, the heat of the outside air is absorbed by the water inside the tube 32 through the radiator by the fan 34a and then released from the water inside the tube 32 to the surface of the Peltier element 31c that contacts the tube 32. Therefore, the neck cooling / warming part 31 can efficiently warm the neck 92 of the user 90 by the inner surface 31a.

  Next, the operation of the body temperature regulation system 10 (see FIG. 1) will be described.

  The control unit 22a (see FIG. 3) of the sensor device 20 (see FIG. 3) transmits data measured by the electrocardiograph 22c (see FIG. 3) while the sensor device 20 is powered on. 22d (see FIG. 3) continues to be transmitted wirelessly to the main unit 30 (see FIG. 5). Then, the control unit 36a (see FIG. 5) of the main body device 30 receives the data transmitted by the transmission unit 22d of the sensor device 20 while the power of the main body device 30 is turned on, as shown in FIG. Keeps receiving wirelessly. It should be noted that these communications may be performed intermittently, and how long the communication is repeated depends on the design.

  FIG. 6 is a flowchart of the operation of the body temperature regulation system 10 (see FIG. 1).

  6, the control unit 36a (see FIG. 5) of the main body device 30 (see FIG. 5) receives the electrocardiograph 22c (see FIG. 3) received by the receiving unit 36c (see FIG. 5). Based on the measured data, it is determined whether or not the sympathetic nerve among the autonomic nerves of the user 90 (see FIG. 1) is in a dominant state for a predetermined time (step S61). Thus, the electrocardiograph 22c and the control unit 36a measure the dominant state of the sympathetic nerve and the parasympathetic nerve among the autonomic nerves of the user 90, and constitute the autonomic nerve state measuring unit of the present invention. ing.

  Here, a method for determining whether or not the sympathetic nerve is dominant in the autonomic nerve will be described. This method is a known method using an electrocardiogram. The control unit 36a performs frequency analysis on the fluctuation of the RR interval of the heartbeat based on the electrocardiogram which is measurement data of the electrocardiograph 22c, and the low frequency component LF mainly reflecting the sympathetic nerve and the high frequency mainly reflecting the parasympathetic nerve. The component HF is obtained, and if the ratio LF / HF ratio is larger than a predetermined value, it is determined that the sympathetic nerve is dominant in the autonomic nerve.

  If the control unit 36a determines in step S61 that the sympathetic nerve of the autonomic nerves is not in the dominant state for a predetermined time, the control unit 36a performs the process of step S61 again. On the other hand, when the control unit 36a determines in step S61 that the sympathetic nerve in the autonomic nerve is in the dominant state for a predetermined time, the control state of the voltage supplied to the Peltier element 31c (see FIG. 5) is the warming state. It is determined whether or not (step S62). Here, the warming state is controlled so that the temperature of the inner surface 31a (see FIG. 4) of the temperature changing unit 31 (see FIG. 4) becomes a predetermined temperature higher than the average human deep body temperature. It is the state that was done.

  When the control unit 36a determines in step S62 that the control state of the voltage supplied to the Peltier element 31c is the heating state, the control unit 36a sets the control state of the voltage supplied to the Peltier element 31c to the cooling state (step S63), and then performs the step again. The process of S61 is performed. Here, the cooling state is a state in which the temperature of the inner surface 31a of the temperature changing unit 31 is controlled to be a predetermined temperature lower than the average human deep body temperature. As described above, the control unit 36a causes the cervical cooling / warming unit 31 to perform heating when the sympathetic nerve of the user 90 continues to be dominant for a predetermined time after the cervical cooling / warming unit 31 performs heating. To cool down.

  If the control unit 36a determines in step S62 that the control state of the voltage supplied to the Peltier element 31c is not the heating state, the control unit 36a sets the control state of the voltage supplied to the Peltier element 31c to the heating state (step S64), and again. The process of step S61 is performed. As described above, the control unit 36a causes the cervical cooling / heating unit 31 to perform cooling when the sympathetic nerve of the user 90 continues to be dominant for a predetermined time after the cervical cooling / heating unit 31 performs cooling. Heating is executed.

  It is conceivable that the human body reacts with delay to the operation of the body temperature regulation system 10. For example, it may be considered that it takes some time until the state of the autonomic nerve changes after the control unit 36a changes the temperature of the inner surface 31a of the neck cooling / heating unit 31. Therefore, the control unit 36a may insert an appropriate waiting time when returning to the process of step S61 again immediately after the process of step S63, or when returning to step S61 again immediately after the process of step S64. May be.

  As described above, the body temperature regulation system 10 does not perform heating or cooling only by an objective criterion of temperature as in the past, but by a criterion depending on the user 90 that the sympathetic nerve is dominant. Since warming or cooling is performed, the deep body temperature of the user 90 can be adjusted to a temperature comfortable for the user 90.

  Even if the user 90 performs one of heating and cooling, when the sympathetic nerve of the user 90 continues to be dominant for a predetermined time, for example, the user 90 feels hot but is heated Or the user 90 felt that it was cold but cooled. In such a case, the body temperature adjustment system 10 switches between heating and cooling, so that the deep body temperature of the user 90 can be adjusted to a temperature that is more comfortable for the user 90.

(Second Embodiment)
First, the configuration of the body temperature regulation system according to the second embodiment of the present invention will be described.

  The configuration of the body temperature regulation system according to the present embodiment is the body temperature regulation system 10 according to the first embodiment (see FIG. 1) except for the configuration of the sensor device 20 (see FIG. 7) described below. Therefore, the same components as those of the body temperature regulation system 10 are denoted by the same reference numerals as those of the body temperature regulation system 10 and detailed description thereof is omitted.

  FIG. 7 is a block diagram showing a configuration of the sensor device 20 of the body temperature regulation system according to the present embodiment.

  As shown in FIG. 7, the configuration of the sensor device 20 according to the present embodiment includes a thermometer 122a as a body temperature measuring unit that measures the body surface temperature of the body temperature of the user 90, and the body temperature according to the first embodiment. The sensor device 20 (see FIG. 3) of the adjustment system 10 (see FIG. 1) has the same configuration as that provided in the housing 22 (see FIG. 2).

  Next, the operation of the body temperature regulation system according to the present embodiment will be described.

  The control unit 22a (see FIG. 7) of the sensor device 20 (see FIG. 7) is configured such that the electrocardiograph 22c (see FIG. 7) and the thermometer 122a (see FIG. 7) while the sensor device 20 is powered on. ) Is transmitted wirelessly to the main unit 30 (see FIG. 5) by the transmitter 22d (see FIG. 7). Then, the control unit 36a (see FIG. 5) of the main body device 30 receives the data transmitted by the transmission unit 22d of the sensor device 20 while the power of the main body device 30 is turned on, as shown in FIG. Keeps receiving wirelessly. It should be noted that these communications may be performed intermittently, and how long the communication is repeated depends on the design.

  FIG. 8 is a flowchart of the operation of the body temperature regulation system according to the present embodiment.

  As shown in FIG. 8, the controller 36a (see FIG. 5) of the main body device 30 (see FIG. 5) receives the electrocardiograph 22c (see FIG. 7) received by the receiving unit 36c (see FIG. 5). Based on the measured data, it is determined whether or not the sympathetic nerve is dominant among the autonomic nerves of the user 90 (see FIG. 1) (step S161).

  When the control unit 36a determines in step S161 that the sympathetic nerve is not in the dominant state among the autonomic nerves, the control unit 36a performs the process of step S161 again. On the other hand, if the control unit 36a determines in step S161 that the sympathetic nerve is dominant among the autonomic nerves, based on the measurement data of the thermometer 122a (see FIG. 7) received by the reception unit 36c, the control unit 36a It is determined whether the body surface temperature is rising (step S162).

  When the control unit 36a determines in step S162 that the body surface temperature of the user 90 is rising, the control unit 36a controls the voltage supplied to the Peltier element 31c (see FIG. 5), and the inner surface of the neck cooling / heating unit 31. The temperature of 31a is lowered (step S163), and the process of step S161 is performed again. As described above, the control unit 36a cools the cervical cooling / heating unit 31 based on the body surface temperature of the user 90 measured by the thermometer 122a when it is measured that the sympathetic nerve of the user 90 is dominant. It is supposed to be executed.

  When the controller 36a determines in step S162 that the body surface temperature of the user 90 has not increased, the controller 36a controls the voltage supplied to the Peltier element 31c to increase the temperature of the inner surface 31a of the neck cooling / heating unit 31. (Step S164), the process of step S161 is performed again. As described above, the control unit 36a warms the cervical cooling / warming unit 31 based on the body surface temperature of the user 90 measured by the thermometer 122a when the sympathetic nerve of the user 90 is measured to be dominant. Is supposed to be executed.

  In the above, after determining in step S161 that the sympathetic nerve is dominant among the autonomic nerves, the control unit 36a determines whether the inner surface of the cervical cooling / warming part 31 depends on whether the body surface temperature of the user 90 has increased. Although the temperature of the surface 31a is controlled, it may be controlled by other methods. For example, the control unit 36a determines that the sympathetic nerve is dominant in the autonomic nerve in step S161, and then the inner surface 31a of the cervical cooling / heating unit 31 when the body surface temperature of the user 90 is rising. When the body surface temperature of the user 90 is decreasing, the temperature of the inner surface 31a of the neck cooling / warming part 31 is increased and the body surface temperature of the user 90 is not changed. The temperature of the inner surface 31 a of the neck cooling / heating unit 31 may not be changed. In addition, the control unit 36a does not control the temperature of the inner surface 31a of the neck cooling / warming part 31 by the change in the body surface temperature of the user 90, but the neck cooling / warming part 31 by the body surface temperature of the user 90 itself. The temperature of the inner surface 31a may be controlled. For example, after determining in step S161 that the sympathetic nerve is dominant among the autonomic nerves, the control unit 36a has an inner side of the neck cooling / warming part 31 when the body surface temperature of the user 90 is higher than a predetermined temperature. The temperature of the surface 31a of the user 90 is lowered, and when the body surface temperature of the user 90 is lower than the predetermined temperature, the temperature of the surface 31a inside the neck cooling / warming part 31 is increased, The temperature of the inner surface 31a of the neck cooling / warming part 31 may not be changed when the temperature is a predetermined temperature.

  Further, the control unit 36a does not continue to lower the temperature of the inner surface 31a of the neck cooling / warming part 31 every time it is determined in step S162 that the body surface temperature of the user 90 is rising, but to a predetermined temperature. When the temperature reaches, the temperature of the inner surface 31a of the neck cooling / warming part 31 may be stopped. Similarly, the controller 36a does not continue to raise the temperature of the inner surface 31a of the neck cooling / warming part 31 every time it is determined in step S162 that the body surface temperature of the user 90 has not risen, but a predetermined temperature. When the temperature reaches the temperature, the temperature of the inner surface 31a of the neck cooling / warming part 31 may be stopped.

  In addition, the control unit 36a does not decrease the temperature of the inner surface 31a of the neck cooling / heating unit 31 step by step every time it is determined in step S162 that the body surface temperature of the user 90 is rising. The temperature of the inner surface 31a of the cooling / warming portion 31 may be maintained at a constant temperature lower than the average human deep body temperature. Similarly, every time the controller 36a determines in step S162 that the body surface temperature of the user 90 has not increased, the controller 36a does not increase the temperature of the inner surface 31a of the neck cooling / warming part 31 step by step. The temperature of the inner surface 31a of the partial cooling / warming portion 31 may be maintained at a constant temperature higher than the average human deep body temperature.

  Further, it is conceivable that the human body reacts with a delay to the operation of the body temperature regulation system according to the present embodiment. For example, it may be considered that it takes some time until the state of the autonomic nerve changes after the control unit 36a changes the temperature of the inner surface 31a of the neck cooling / heating unit 31. Therefore, the control unit 36a allows an appropriate waiting time when returning to the process of step S161 again immediately after the process of step S163 or when returning to the process of step S161 again immediately after the process of step S164. May be.

  As described above, the body temperature regulation system according to the present embodiment does not perform heating or cooling only by an objective standard of temperature as in the conventional case, but the user that sympathetic nerve is dominant. Since heating or cooling is performed according to the 90th criterion, the deep body temperature of the user 90 can be adjusted to a temperature comfortable for the user 90.

  Whether the sympathetic nerve of the user 90 is dominant because the user 90 feels hot or the sympathetic nerve of the user 90 is dominant because the user 90 feels cold is the body surface temperature of the user 90 Can be estimated. For example, when the body surface temperature of the user 90 is rising and the sympathetic nerve of the user 90 is dominant, it can be estimated that the user 90 feels hot. Since the body temperature regulation system according to the present embodiment performs heating or cooling based on not only the sympathetic nerve dominant state but also the body surface temperature of the user 90, the deep body temperature of the user 90 is determined by the user 90. The temperature can be adjusted to a more comfortable temperature for the user.

  In the present embodiment, the thermometer 122a is housed inside the housing 22, but of course, the thermometer 122a may be provided outside the housing 22 as a separate body.

  Further, in the present embodiment, the thermometer 122a measures the body surface temperature of the user 90, but may measure the deep body temperature of the user 90. When the thermometer 122a measures the deep body temperature of the user 90, the control unit 36a determines in step S162 whether or not the deep body temperature of the user 90 is rising based on the measurement data of the thermometer 122a. If it is determined in step S162 that the deep body temperature of the user 90 is rising, the process of step S163 is executed. If it is determined in step S162 that the deep body temperature of the user 90 is not rising, the process of step S164 is executed. To do.

(Third embodiment)
First, the configuration of the body temperature regulation system according to the third embodiment of the present invention will be described.

  The configuration of the body temperature regulation system according to the present embodiment is the body temperature regulation system 10 according to the first embodiment (see FIG. 1) except for the configuration of the sensor device 20 (see FIG. 9) described below. Therefore, the same components as those of the body temperature regulation system 10 are denoted by the same reference numerals as those of the body temperature regulation system 10 and detailed description thereof is omitted.

  FIG. 9 is a block diagram showing a configuration of the sensor device 20 of the body temperature regulation system according to the present embodiment.

  As shown in FIG. 9, the configuration of the sensor device 20 according to the present embodiment includes a hygrometer 222a as a sweating state measurement unit for measuring the sweating state of the user 90, and a body temperature according to the first embodiment. The sensor device 20 (see FIG. 3) of the adjustment system 10 (see FIG. 1) has the same configuration as that provided in the housing 22 (see FIG. 2).

  Next, the operation of the body temperature regulation system according to the present embodiment will be described.

  The control unit 22a (see FIG. 9) of the sensor device 20 (see FIG. 9) is configured such that the electrocardiograph 22c (see FIG. 9) and the hygrometer 222a (see FIG. 9) while the sensor device 20 is powered on. .) Is continuously transmitted to the main unit 30 (see FIG. 5) by the transmitter 22d (see FIG. 9). Then, the control unit 36a (see FIG. 5) of the main body device 30 receives the data transmitted by the transmission unit 22d of the sensor device 20 while the power of the main body device 30 is turned on, as shown in FIG. Keeps receiving wirelessly. It should be noted that these communications may be performed intermittently, and how long the communication is repeated depends on the design.

  FIG. 10 is a flowchart of the operation of the body temperature regulation system according to the present embodiment.

  As shown in FIG. 10, the controller 36a (see FIG. 5) of the main body device 30 (see FIG. 5) receives the electrocardiograph 22c (see FIG. 9) received by the receiving unit 36c (see FIG. 5). Based on the measured data, it is determined whether or not the sympathetic nerve is dominant among the autonomic nerves of the user 90 (see FIG. 1) (step S261).

  If the control unit 36a determines in step S261 that the sympathetic nerve is not in the dominant state among the autonomic nerves, the control unit 36a performs the process of step S261 again. On the other hand, when the control unit 36a determines in step S261 that the sympathetic nerve is dominant among the autonomic nerves, based on the measurement data of the hygrometer 222a (see FIG. 9) received by the reception unit 36c, the user 90 Whether or not is sweating is determined (step S262).

  When the control unit 36a determines that the user 90 is sweating in step S262, the control unit 36a controls the voltage supplied to the Peltier element 31c (see FIG. 5) to control the temperature of the inner surface 31a of the neck cooling / heating unit 31. (Step S263), and the process of step S261 is performed again. As described above, when the sympathetic nerve of the user 90 is measured, the control unit 36a causes the cervical cooling / heating unit 31 to perform cooling based on the sweating state measured by the hygrometer 222a. It has become.

  When determining in step S262 that the user 90 is not sweating, the control unit 36a controls the voltage supplied to the Peltier element 31c to increase the temperature of the inner surface 31a of the neck cooling / heating unit 31 (step S264). Then, the process of step S261 is performed again. As described above, the control unit 36a causes the cervical cooling / heating unit 31 to perform heating based on the sweating state measured by the hygrometer 222a when the sympathetic nerve of the user 90 is measured to be dominant. It has become.

  When the control unit 36a reaches the predetermined temperature instead of continuously lowering the temperature of the inner surface 31a of the neck cooling / heating unit 31 every time it is determined in step S262 that the user 90 is sweating, The lowering of the temperature of the inner surface 31a of the neck cooling / heating portion 31 may be stopped. Similarly, the control unit 36a does not continue to raise the temperature of the inner surface 31a of the neck cooling / warming unit 31 every time it is determined in step S262 that the user 90 is not sweating, but reaches a predetermined temperature. Alternatively, the temperature of the inner surface 31a of the neck cooling / warming part 31 may be stopped from being raised.

  In addition, the control unit 36a does not decrease the temperature of the inner surface 31a of the neck cooling / warming unit 31 step by step every time it is determined in step S262 that the user 90 is sweating. The temperature of the inner surface 31a may be maintained at a constant temperature lower than the average human deep body temperature. Similarly, the controller 36a does not increase the temperature of the inner surface 31a of the neck cooling / warming part 31 step by step every time it is determined in step S262 that the user 90 is not sweating, but the neck cooling / warming part 31. The inner surface 31a may be maintained at a constant temperature higher than the average human deep body temperature.

  Further, it is conceivable that the human body reacts with a delay to the operation of the body temperature regulation system according to the present embodiment. For example, it may be considered that it takes some time until the state of the autonomic nerve changes after the control unit 36a changes the temperature of the inner surface 31a of the neck cooling / heating unit 31. Therefore, the control unit 36a allows an appropriate waiting time when returning to the process of step S261 again immediately after the process of step S263 or when returning to the process of step S261 again immediately after the process of step S264. May be.

  As described above, the body temperature regulation system according to the present embodiment does not perform heating or cooling only by an objective standard of temperature as in the conventional case, but the user that sympathetic nerve is dominant. Since heating or cooling is performed according to the 90th criterion, the deep body temperature of the user 90 can be adjusted to a temperature comfortable for the user 90.

  Whether the sympathetic nerve of the user 90 is dominant because the user 90 feels hot or whether the sympathetic nerve of the user 90 is dominant because the user 90 feels cold is in the sweating state of the user 90. Can be estimated. For example, when the user 90 is sweating and the sympathetic nerve of the user 90 is dominant, it can be estimated that the user 90 feels hot. The body temperature regulation system according to the present embodiment performs heating or cooling based not only on the dominant state of the sympathetic nerve but also on the sweating state of the user 90, so that the deep body temperature of the user 90 is given to the user 90. Furthermore, it can be adjusted to a comfortable temperature.

  In the present embodiment, the hygrometer 222 a is housed inside the housing 22, but of course, it may be provided outside the housing 22 as a separate body from the housing 22.

  In each of the above-described embodiments, the body temperature regulation system can perform heating and cooling for the user 90, but can perform only one of heating and cooling for the user 90. It may be. For example, when only cooling can be performed on the user 90, the body temperature regulation system is suitable for being used by the user 90 on a day when the user 90 feels hot. When user becomes dominant, the user 90 may be cooled.

(Fourth embodiment)
First, the structure of the body temperature regulation system which concerns on the 4th Embodiment of this invention is demonstrated.

  The configuration of the body temperature regulation system according to the present embodiment is the body temperature regulation system 10 according to the first embodiment (see FIG. 1) except for the configuration of the sensor device 20 (see FIG. 11) described below. Therefore, the same components as those of the body temperature regulation system 10 are denoted by the same reference numerals as those of the body temperature regulation system 10 and detailed description thereof is omitted.

  FIG. 11 is a block diagram showing a configuration of the sensor device 20 of the body temperature regulation system according to the present embodiment.

  As shown in FIG. 11, the configuration of the sensor device 20 according to the present embodiment includes a three-dimensional acceleration sensor 322a as a motion measuring unit that measures the movement of the user 90, and a body temperature regulation system according to the first embodiment. 10 (see FIG. 1) has the same configuration as the sensor device 20 (see FIG. 3) provided inside the housing 22 (see FIG. 2).

  Next, the operation of the body temperature regulation system according to the present embodiment will be described.

  The control unit 22a (see FIG. 11) of the sensor device 20 (see FIG. 11) is connected to the electrocardiograph 22c (see FIG. 11) and the three-dimensional acceleration sensor 322a (see FIG. 11) while the sensor device 20 is powered on. 11) is continuously transmitted to the main unit 30 (see FIG. 5) by the transmitter 22d (see FIG. 11). Then, the control unit 36a (see FIG. 5) of the main body device 30 receives the data transmitted by the transmission unit 22d of the sensor device 20 while the power of the main body device 30 is turned on, as shown in FIG. Keeps receiving wirelessly. It should be noted that these communications may be performed intermittently, and how long the communication is repeated depends on the design.

  FIG. 12 is a flowchart of the operation of the body temperature regulation system according to the present embodiment.

  As shown in FIG. 12, the control unit 36a (see FIG. 5) of the main body device 30 (see FIG. 5) receives the three-dimensional acceleration sensor 322a (see FIG. 11) received by the receiving unit 36c (see FIG. 5). ) Is determined whether or not the user 90 (see FIG. 1) lies down and stops (step S361).

  If it is determined in step S361 that the user 90 is not lying down or the user 90 is not stopped, the control unit 36a performs the process of step S361 again. On the other hand, when the control unit 36a determines in step S361 that the user 90 is lying down and stopped, the user 90 is based on the measurement data of the electrocardiograph 22c (see FIG. 11) received by the receiving unit 36c. It is determined whether the sympathetic nerve is in the dominant state among the autonomic nerves (step S362).

  If the control unit 36a determines in step S362 that the sympathetic nerve is not in the dominant state among the autonomic nerves, the control unit 36a performs the process of step S361 again. On the other hand, when the control unit 36a determines in step S362 that the sympathetic nerve is dominant among the autonomic nerves, the control unit 36a controls the voltage supplied to the Peltier element 31c (see FIG. 5) to control the inside of the neck cooling / heating unit 31. The temperature of the surface 31a is lowered (step S363), and the process of step S361 is performed again. As described above, when the three-dimensional acceleration sensor 322a measures that the user 90 is lying down and stopped, the control unit 36a determines that the sympathetic nerve of the user 90 is dominant. The partial cooling / heating unit 31 is allowed to perform cooling.

  When the control unit 36a reaches a predetermined temperature instead of continuously lowering the temperature of the inner surface 31a of the cervical cooling / heating unit 31 every time it is determined in step S362 that the sympathetic nerve is dominant among the autonomic nerves Alternatively, the lowering of the temperature of the inner surface 31a of the neck cooling / warming part 31 may be stopped.

  The controller 36a does not decrease the temperature of the inner surface 31a of the cervical cooling / warming part 31 step by step, but determines that the sympathetic nerve is dominant among the autonomic nerves in step S362. The temperature of the inner surface 31a of the part 31 may be maintained at a constant temperature lower than the average human deep body temperature.

  Further, it is conceivable that the human body reacts with a delay to the operation of the body temperature regulation system according to the present embodiment. For example, it may be considered that it takes some time until the state of the autonomic nerve changes after the control unit 36a changes the temperature of the inner surface 31a of the neck cooling / heating unit 31. Therefore, the control unit 36a may insert an appropriate waiting time when returning to the process of step S361 again immediately after the process of step S363.

  As described above, the body temperature regulation system according to the present embodiment does not perform cooling based only on the objective criterion of temperature as in the conventional case, but depends on the user 90 that the sympathetic nerve is dominant. Since cooling is performed based on the reference, the deep body temperature of the user 90 can be adjusted to a temperature comfortable for the user 90.

  It is known that when a human enters sleep, the body temperature is released to lower the deep body temperature. For this reason, humans can easily sleep by being slightly cooled from the outside, and can take good sleep. The body temperature regulation system according to the present embodiment determines that the user 90 is about to go to sleep because the user 90 is lying and stopped, and the user 90 is about to go to sleep. When the sympathetic nerve is dominant among the 90 autonomic nerves, that is, when the user 90 is not relaxed, a cooling operation is performed on the user 90. Therefore, the body temperature regulation system according to the present embodiment can guide the user 90 to sleep by adjusting the deep body temperature of the user 90 who is going to sleep to a temperature comfortable for the user 90. On the other hand, if this mechanism is used in reverse, it can be applied to wake-up guidance.

  In the present embodiment, the three-dimensional acceleration sensor 322a is housed inside the housing 22, but of course, it may be provided outside the housing 22 as a separate body.

  The control unit 36a controls the neck cooling / heating unit 31 based on the measurement result of the electrocardiograph 22c in the first embodiment, and the electrocardiograph 22c and the electrocardiograph 22c in the second embodiment. The neck cooling / warming part 31 is controlled based on the measurement result of the thermometer 122a, and the neck cooling / warming part 31 is controlled based on the measurement result of the electrocardiograph 22c and the hygrometer 222a in the third embodiment. In the fourth embodiment, the neck cooling / heating unit 31 is controlled based on the measurement results of the electrocardiograph 22c and the three-dimensional acceleration sensor 322a. Complex control combined with each other may be performed.

  Moreover, in each embodiment mentioned above, although the communication between the sensor apparatus 20 and the main body apparatus 30 is wireless communication, of course, wired communication may be sufficient.

  Moreover, in each embodiment mentioned above, the control part 36a judges based on an electrocardiogram whether the sympathetic nerve is the dominant state among autonomic nerves. However, the controller 36a may determine whether or not the sympathetic nerve is dominant among the autonomic nerves by a method other than the electrocardiogram. As a method for determining whether or not the sympathetic nerve is dominant among the autonomic nerves, for example, a method of analyzing blood pressure, skin electrical reflex, pupil diameter, and the like is known.

  Moreover, in each embodiment mentioned above, since the neck cooling / warming part 31 performs a heating and cooling with respect to the user's 90 neck 92, the deep body temperature of the user 90 is made easy. Can be changed. However, the body temperature adjustment operation unit of the present invention may have a configuration other than the neck cooling / warming unit 31 as long as the operation for adjusting the body temperature of the user 90 can be executed. For example, the body temperature adjustment operation unit may be clothes to which a cooling / heating device for adjusting the body temperature of the wearer is attached.

  Moreover, in each embodiment mentioned above, since the body temperature control system is portable by the user 90, even if the user 90 moves, the body temperature of the user 90 is made a comfortable temperature for the user 90. Can be adjusted. However, the body temperature regulation system may not be portable as long as an operation for regulating the body temperature of the user 90 can be executed. For example, when the user 90 is in the room, in the body temperature regulation system, an air conditioner installed in the room may constitute the body temperature regulation operation unit of the present invention.
