Description

  The present invention relates to a biological risk evaluation apparatus that evaluates the risk of developing heat stroke or dehydration in a living body.

  In elderly people, dry mouth may cause a feeling of dryness due to a decrease in the central nervous system of the thirst. It is feared that elderly people have a reduced function of temperature regulation and cause dehydration not only on hot days due to insufficient water intake but also when the temperature changes drastically. In addition, since the Olympics are scheduled to be held in Tokyo in the hot season of 2020, there are concerns about not only dehydration but also the onset of heat stroke. Under such circumstances, a heatstroke warning device has been proposed that warns the user of the risk of developing heatstroke by monitoring changes in the deep body temperature of the user. The heat stroke alarm device has an external shape that can be held by the user's external auditory canal and auricle by integrating an earplug part inserted into the external auditory canal and a main body case located facing the auricle. The earplug part incorporates a tympanic temperature sensor for measuring deep body temperature, and the main body case evaluates thermal strain based on deep body temperature information from the eardrum temperature sensor, and issues a heat stroke alarm according to the evaluation. The device was built-in (see, for example, Patent Document 1).

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The biological risk evaluation apparatus 1 will be described with reference to FIG. The biological risk evaluation apparatus 1 measures at least one of the temperature sensation of the living body or the degree of transpiration of water from the surface of the living body, and based on the measured temperature sensation of the living body or the degree of transpiration of water from the living body surface. The risk of developing heat stroke or dehydration is evaluated. Specifically, the biological risk evaluation apparatus 1 includes at least a measurement unit 10 and an evaluation unit 20. The living body means the whole living thing, and includes not only humans but also animals. In addition, the degree of transpiration of water from the surface of a living body means the degree of transpiration of water that is transpirated through sweat glands (that is, sweat) and the degree of transpiration of water that evaporates from the skin and mucous membranes. It includes any degree of excretion. Moreover, as a transpiration | evaporation degree, the amount of transpiration | evaporation of the water per unit area of the biological body surface is mentioned, for example. Hereinafter, the transpiration degree of moisture from the surface of the living body is simply referred to as the transpiration degree.

  The measurement unit 10 measures the temperature sensation of the living body and the degree of transpiration. Specifically, the measurement unit 10 includes a temperature sensation measurement unit 11 and a transpiration degree measurement unit 16. The temperature sensation measuring unit 11 measures a temperature sensation of a living body, and includes, for example, a heat donating unit 12, a temperature detecting unit 13, and a sensory action detecting unit 14.

  The heat donating unit 12 applies heat or cold to a predetermined part of the living body. When the heat donating unit 12 applies heat to a predetermined part of the living body, the predetermined part of the living body is heated. When the heat donating unit 12 applies cold to a predetermined part of the living body, the predetermined part of the living body is cooled. The heat supply unit 12 is controlled by a control unit related to heat supply (not shown), and the temperature changes as described above. And the heat | fever provision part 12 has the temperature change part 12a. The temperature change part 12a gives a temperature change to a predetermined part of the living body. Examples of the temperature change mode include a temperature rise due to heat (heating, etc.) and a temperature drop due to heat (cooling, endotherm, etc.).

  Examples of the heat donating unit 12 include a temperature transmission mechanism using a Peltier element (hereinafter referred to as a Peltier element temperature transmission mechanism). An example of the temperature transmission mechanism is a mechanism in which a radiating fin and a heater are brought into contact with one side of the Peltier element and a radiating member is brought into contact with the other side of the Peltier element. The heat transfer direction of the Peltier element is controlled by the Peltier element control unit. When warm heat is generated from the heat dissipation member, the heater is turned on, and the heat of the heater is transferred to the heat dissipation member through the Peltier element. When cold heat is generated from the heat radiating member, the heater is turned off, and the heat of the heat radiating member is transferred to the heat radiating fin through the Peltier element. In addition, the aspect of the heat | fever provision part 12 is not limited to this, The thing which can give another temperature change may be sufficient.

  The biological risk evaluation apparatus 1 may be configured so that the temperature change condition in the temperature change unit 12a can be set. In this case, a temperature setting unit 19a and a temperature gradient setting unit 19b are separately provided. The temperature setting unit 19a sets a start temperature when a temperature change is given to a predetermined part of the living body among the temperature change conditions. As the start temperature, for example, a temperature in the vicinity of a human body temperature (for example, 36 ° C.) can be mentioned. Moreover, the temperature setting part 19a may be able to set the upper limit temperature (for example, 42 degreeC) or the lower limit temperature (for example, 20 degreeC) of a temperature change among temperature change conditions. If the upper limit temperature of the temperature change in the temperature changing unit 12a can be set in the vicinity of the temperature at which a low temperature burn is given to the living body, the risk of causing the low temperature burn to the measuring target living body can be reduced. The temperature gradient setting unit 19b sets a gradient in which the temperature changes when a temperature change is applied to a predetermined part of the living body, among the temperature change conditions. As an example of the gradient in which the temperature changes, an example in which the temperature is raised or lowered by 1 ° C. every 3 seconds is given as an example. However, the temperature is not limited thereto, and other temperature changing modes may be used. The temperature changing unit 12a operates according to these settings.

  The temperature detecting unit 13 detects a temperature at or near a predetermined part of the living body to which the temperature change is given by the temperature changing unit 12a, or a temperature at or near a predetermined part of the heat donating unit 12. Examples of the temperature detection unit 13 include a temperature sensor using a thermistor or the like. However, the temperature detection unit 13 is not limited to this and may be capable of detecting other temperatures. In the following description of the biological risk evaluation apparatus 1, the temperature detected by the temperature detection unit 13 will be described as being a temperature at or near a predetermined part of the living body to which the temperature change is given by the temperature change unit 12a. However, what replaced this with the temperature of the predetermined part of the heat | fever provision part 12, or its vicinity is also contained in this invention.

  Examples of the predetermined part of the living body include, for example, the forearm part and the upper arm part in the case of a human being, but are not limited thereto, and other parts (eg, legs, feet, abdomen, chest, back, etc.) There may be. In addition, examples of the predetermined part of the living body include parts corresponding to human forearms and upper arms according to human beings other than humans, but are not limited thereto, and other parts (for example, It may be a part corresponding to a human leg, foot, belly, chest, back, or the like.

  Moreover, it is preferable that the part of the living body that gives the temperature change in the temperature changing unit 12a and the part of the living body that detects the temperature in the temperature detecting unit 13 are substantially the same position or the vicinity as described above. It is not limited, and it may be in a remote position.

  The sensory action detection unit 14 detects a sensory action indicating that the living body senses a temperature change. When a living body senses a temperature change, for example, when a temperature rise change is given to a predetermined part of the living body, the living body senses a temperature change when the living body becomes hot at a temperature in the process of the temperature rise change. Further, when a temperature decrease change is given to a living body, the living body senses a temperature change when the living body becomes cold at a temperature where the temperature decrease change process is performed. Hereinafter, the sense that the living body is heated due to a temperature rise or the skin sensation due to stimulation at a temperature higher than the body temperature is referred to as warm sense. Moreover, the sense that the living body has become cold caused by a decrease in temperature or the sensation that occurs at a temperature lower than the body temperature is called cold sensation. Further, the temperature sensation includes both the above-described warm sense and cold sense. The sensory motion detection unit 14 detects the motion of the living body when the living body senses warm or cold as described above.

  The sensory motion detection unit 14 includes, for example, one provided with a living body support unit that comes into contact with a part of the living body. In this case, the sensory action detection unit 14 can be configured to detect as a sensory action when a part where the living body is in contact with the living body support part is moved away from the living body support part. An example of such a sensory movement detection unit 14 is a configuration using a press switch, a contact sensor, or the like. When the living body presses the push switch or the living body senses a temperature change while the living body is in contact with the contact sensor, a sensory action is detected when the living body support portion of the living body is separated from the push switch or the contact sensor. Moreover, you may make the sensory action detection part 14 detect as sensory action, when a biological body contacts the biological support part or presses the biological support part. In this case, for example, the sensory motion detection unit 14 may be configured by a switch that a person holds and operates. When the sensory motion detection unit 14 is configured by a switch that a person operates with a hand, when a person senses a temperature change, the sensory motion is detected by operating the switch that the person operates with a hand. .

  The transpiration degree measurement unit 16 measures the transpiration degree, and includes, for example, a covering unit 17 and a moisture amount detection unit 18.

  The covering portion 17 covers at least a part of the living body in a substantially sealed state. As the covering portion 17, for example, a member that has an opening and can cover the living body portion in a substantially sealed state when the opening portion is brought into contact with a predetermined portion of the living body is assumed.

  The water content detection unit 18 detects the water content in the space between the covering unit 17 and the living body. Examples of the moisture amount detection unit 18 include a capacitance type moisture detection sensor. However, the moisture amount detection unit 18 is not limited to this, and may be capable of detecting other moisture amounts. For example, the moisture amount detection unit 18 may be provided inside the coating unit 17.

  The evaluation unit 20 evaluates the risk of developing heat stroke or dehydration based on at least one of the temperature sensation or the degree of transpiration of the living body, and includes a sensory temperature acquisition unit 21, a water content acquisition unit 22, Evaluation index deriving means 23. The sensory temperature acquisition means 21 acquires the temperature detected by the temperature detector 13 as the sensory temperature when the sensory action detector 14 detects a sensory action. The sensory temperature refers to a temperature at which a temperature change such as a living body is hot or cold is felt. The moisture content acquisition means 22 acquires the moisture content detected by the moisture content detector 18.

  The evaluation index deriving unit 23 derives an evaluation index indicating the degree of risk of developing heat stroke or dehydration. The evaluation index deriving unit 23 derives an evaluation index indicating the degree of the risk of developing heat stroke or dehydration, based on the sensory temperature acquired by the sensory temperature acquiring unit 21 and the water amount acquired by the water amount acquiring unit 22. Based on both or one of them.

  The evaluation unit 20 can be mainly composed of a CPU, a ROM, a RAM, a storage device such as a flash memory, and an input device such as a button. The sensory temperature acquisition means 21, the moisture content acquisition means 22, and the evaluation index derivation means 23 can be realized by the CPU executing various programs.

  The display unit 30 displays an evaluation index indicating the degree of heat stroke or dehydration risk derived by the evaluation index deriving unit 23. Examples of the display mode of the evaluation index in the display unit 30 include various modes such as display with specific numbers and display with five-level evaluation. In addition, the aspect which is not contained in the evaluation part 20 as shown in FIG. 1 may be sufficient as the display part 30, and the aspect contained in the evaluation part 20 integrally with the evaluation part 20 may be sufficient as it.

  According to the biological risk evaluation apparatus 1, an evaluation index indicating the degree of onset risk of heat stroke or dehydration in the measurement target living body can be derived from the measurement result measured by the measurement unit 10, so It is possible to grasp how much risk of the onset of the disease. Thereby, even in a hot situation, it can act to prevent the onset of heat stroke or dehydration.

  Next, with reference to FIG. 2 and FIG. 3, the biological risk evaluation apparatus 2 which actualized the biological risk evaluation apparatus 1 is demonstrated. In addition, about the part corresponding to the biological risk evaluation apparatus 1, the name and code | symbol similar to the name and code | symbol used with the biological risk evaluation apparatus 1 are used. In the following description, human beings will be mainly described, but the present invention can be appropriately applied to living organisms other than human beings.

  The biological risk evaluation apparatus 2 includes a measurement unit 10, an evaluation unit 20, a display unit 30, and a housing 40. The housing 40 accommodates the measurement unit 10, the evaluation unit 20, and the display unit 30. The housing 40 includes a living body support unit 41 that comes into contact with a part of the living body.

  As shown in FIG. 3, it is preferable to place the front side (front elbow part, front upper arm part) of the arm such as the forearm part 92 among the arms of the measurement subject 90 on the living body support part 41. This is because the skin on the front side of the arm is thinner than the back side of the arm, and the temperature sensation is easily transmitted. However, the present invention is not limited to this, and the living body support portion 41 may be provided with the rear side of the arm (rear elbow portion, rear upper arm portion) and other parts including the rear forearm portion 91 and the like. Good. Moreover, the shape of the biological support part 41 is preferably an aspect in which, for example, the front side of the arm or the rear side part of the arm is curved so that the front side of the arm or the rear side of the arm can be comfortably placed.

  The temperature sensation measuring unit 11 (heat donating unit 12, temperature detecting unit 13, sensory action detecting unit 14) in the measuring unit 10 is provided in the living body support unit 41 as shown in FIG.

Further, when the measurement subject 90 places the forearm portion 92 on the living body support portion 41, the thermistor is provided in the living body support portion 41 in such a manner that the temperature of the forearm portion 92 can be measured. Further, when the measurement subject 90 places the forearm portion 92 on the living body support portion 41, the push switch is provided in the living body support portion 41 in such a manner that the pressure switch contacts the forearm portion 92. Further, the push switch is provided in the living body support unit 41 in a state in which the pressing switch can reciprocate from the surface of the living body support unit 41 in the out-of-plane direction by an urging force. And in the initial state in which no external force is applied, the push switch is in a state of protruding outward in the out-of-plane direction on the surface of the biological support portion 41 by the biasing force. Therefore, when the measurement subject 90 places the forearm portion 92 on the living body support portion 41, the pressing switch slides inward in the out-of-plane direction and is pushed into the living body support portion 41.

  When measuring the temperature sensation of the measurement subject 90 in the above state, for example, the temperature of the Peltier element is increased. When the temperature change is sensed when the measurement subject 90 is heated by the Peltier element, the forearm portion 92 is separated from the living body support portion 41. When the forearm portion 92 is separated from the living body support portion 41, the push switch slides and protrudes outward from the surface of the living body support portion 41 by the biasing force. When the push switch is in this state, the sensory action of the measurement subject 90 is detected.

  Moreover, when measuring the cold sensation of the measurement subject 90 in the above state, for example, the temperature of the Peltier element is lowered. When the measurement subject 90 feels a change in temperature when the measurement subject 90 is cooled by the Peltier element, the measurement subject 90 moves the forearm portion 92 away from the living body support portion 41. When the forearm portion 92 is moved away from the living body support portion 41 (away from the living body support portion 41), the pressing switch slides and protrudes outward from the surface of the living body support portion 41 by the urging force. When the push switch is in this state, the sensory action of the measurement subject 90 is detected.

  With the above configuration, the temperature sensation measurement unit 11 can measure the temperature sensation simply by placing a predetermined part such as the forearm portion 92 of the measurement subject 90 on the living body support unit 41. Easy. In addition, when it is hot or cold, the operation of separating a predetermined part such as the forearm 92 from the living body support unit 41 can be performed by conditional reflection, so that it is easy to measure the temperature sensation of the person 90 to be measured. Can be done.

  On the other hand, when the sensory motion detection unit 14 is configured by a switch that is operated by a person with a hand, the sensory operation of the measurement subject 90 is detected by the measurement subject 90 operating the switch. In such a configuration, the sensory action is detected after the measurement subject 90 recognizes the heat and coldness.

  In addition, a moisture amount detection unit (not shown) provided inside the covering unit 17 in the biological risk evaluation apparatus 2 is connected to the evaluation unit 20 accommodated in the housing 40 through the wiring 16a.

As the display unit 30 in the biological risk evaluation apparatus 2, a temperature display unit 31, a transpiration degree display unit 32, and an onset risk stage evaluation display unit 33 are provided. The temperature display unit 31 displays, for example, the temperature detected by the temperature detection unit 13 when a sensory action is detected. The transpiration degree display unit 32 displays, for example, the transpiration degree of the living body measured by the transpiration degree measurement unit 16.

  The onset risk stage evaluation display unit 33 externally displays the onset risk of heat stroke and dehydration derived by the evaluation unit 20 as a stage evaluation. As an external display mode, for example, a mode in which only the corresponding stage evaluation part is lit using an LED or the like can be mentioned. As shown in FIG. 2, the onset risk stage evaluation display unit 33 evaluates the onset risk of heat stroke and dehydration by five levels based on facial expressions, but is not limited to this.

May be displayed. As an evaluation index of the risk of developing heat stroke, for example, a numerical value indicating a ratio indicating the possibility of the risk of developing heat stroke is given as an example. The numerical value indicating the ratio of the risk of developing heat stroke is, for example, both the sensory temperature acquired by the sensory temperature acquisition means and / or the water content acquired by the water content acquisition means. As an example, it is assumed that the function is derived by a predetermined function expression using as a variable. Moreover, as an evaluation index of the onset risk of other heat strokes, for example, those expressed by a five-step evaluation of A to E can be mentioned.

  Although not shown in FIG. 2, a display for displaying an evaluation index of the risk of developing dehydration may be added to the display unit 30 or provided instead of the onset risk stage evaluation display unit 33.

  As shown in FIG. 4, the fixing portion 163 includes a sandwiching member 166 that is formed in a substantially U shape together with the sealed space forming member 162. The sandwiching movable member 169 in the sandwiching member 166 can be slid along the arrow direction in FIG. 4 so as to open and close the U-shaped opening by a slide moving mechanism (not shown). Therefore, as shown in FIG. 4, if the arm or the like of the measurement subject 90 is arranged in the U-shaped opening, the sealed space forming member 162 can be fixed to the arm or the like of the measurement subject 90 by the clamping member 166.

  For example, as shown in FIG. 5, the fixing portion 163 can fix the sealed space forming member 162 to the forearm portion 94 of the measurement subject 90. The opening 165 of the sealed space forming member 162 is brought into contact with the forearm 92 and the movable movable member 169 is slid in the direction of the arrow shown in FIG. The member 162 can be fixed. When the sealed space forming member 162 is fixed to the arm, the position where the sealed space forming member 162 is fixed is preferably the upper arm rather than the forearm as it gets older. This is because the part closer to the trunk tends to sweat as you get older.

  As described above, the fixing portion 163 has a mode in which the sealed space forming member 162 is fixed to a predetermined part of the living body by sandwiching the predetermined part of the living body together with the sealed space forming member 162, or a rubber wound around the arm. Although the thing which fixes the sealed space formation member 162 to the predetermined site | part of a biological body with a band is mentioned, It is not limited to this, If the sealed space formation member 162 can be fixed to the predetermined site | part of a biological body Any mode may be used. Thereby, the predetermined site | part of a biological body can be coat | covered in a substantially sealed state.

  If the attachment position of the covering portion 17 in the living body is, for example, the upper arm portion and the forearm portion is placed on the living body support portion 41 provided with the temperature sensation measuring portion 11, as shown in FIG. These measurements can be performed simultaneously.

  The moisture amount detection unit 18 is provided at any position on the inner peripheral wall of the sealed space forming member 162. The moisture amount detection unit 18 is assumed to be, for example, a capacitance type moisture detection sensor as an example, but is not limited to this, and may be another moisture detection sensor.

  If the transpiration degree measuring unit 16 is configured as described above, a substantially sealed space can be easily formed in a part of a biological arm or the like as shown in FIG. And if the water | moisture content detection part 18 detects the water | moisture content transpired from the biological body surface in substantially sealed space, the transpiration | evaporation degree of the measuring subject 90 can be measured.

  Next, an example of the operation of the biological risk evaluation apparatus 2 will be described with reference to FIG. First, the temperature setting unit 19a requests setting of the start temperature of the temperature changing unit 12a (Peltier element temperature transmission mechanism) (S101). When the setting of the start temperature of the temperature change unit 12a is completed, the temperature change unit 12a (Peltier element temperature transmission mechanism) rises to the set start temperature (S102). In step S101, the temperature setting unit 19a may further request the upper limit temperature or the lower limit temperature of the temperature change.

  When the temperature changing unit 12a (Peltier element temperature transmission mechanism) rises to the set start temperature, the temperature gradient setting unit 19b requests setting of the temperature gradient of the temperature changing unit 12a (Peltier element temperature transmission mechanism) (S103). ). Here, for example, a temperature gradient in the case of a temperature rise and a temperature gradient in the case of a temperature drop are set with respect to the temperature changing unit 12a (Peltier element temperature transmission mechanism). Here, both temperature gradients may be set, or only one of the temperature gradients may be set. The temperature gradient can be set to increase or decrease by 1 ° C. (m> 0) every 5 seconds (n> 0), for example.

  When both temperature gradients are set as described above, the temperature changing unit 12a (Peltier element temperature transmission mechanism) next increases the temperature from the start temperature or decreases the temperature from the start temperature. Is requested (S104). If only one of the settings is performed in step S103, the process in step S104 may not be performed.

  When step S104 is completed, the temperature changing unit 12a (Peltier element temperature transmission mechanism) requests measurement start relating to the sensory temperature (S105). When the measurement starts, the temperature changing unit 12a (Peltier element temperature transmission mechanism) increases or decreases in temperature according to the above setting. Note that the measurement subject 90 (see FIG. 3) may place the forearm portion 92 on the living body support portion 41 at any time as long as the sensory temperature measurement is started (step S105). That is, the timing may be any time from before step S101 to the start of measurement related to the sensory temperature in step S105.

  Here, until the sensory motion is detected by the sensory motion detection unit 14 (S106), the temperature changing unit 12a (Peltier element temperature transmission mechanism) continuously increases or decreases the temperature according to the above setting. When the sensory motion is detected by the sensory motion detector 14, the sensory temperature acquisition means 21 acquires the temperature detected by the temperature detector 13 when the sensory motion is detected as the sensory temperature (S107). If a sensory action related to one of the temperature rise and the temperature drop is detected, the measurement start of the other of the temperature rise and the temperature drop is requested thereafter, as in the process shown in step S105. It may be. Then, sensory motion detection similar to the processing shown in step S106 is performed.

  Next, the water content detection unit 18 requests the start of measurement related to the degree of transpiration (S108). At this time, the measurement subject sets the covering portion 17 on the arm or the like as shown in FIGS. 4 and 5 before the start of measurement related to the degree of transpiration. Then, for example, when the measurement subject presses the measurement start button 34 shown in FIG. 2, the moisture amount detection unit 18 starts measurement, and detection of the moisture amount in the sealed space forming member 162 is started.

  Here, the moisture content acquisition means 22 acquires, for example, the moisture content (humidity) in the sealed space forming member 162 immediately after pressing the measurement start button 34 from the moisture content detection unit 18 as the start moisture content (S109). Next, the moisture content acquisition unit 22 acquires the moisture content (humidity) in the sealed space forming member 162 from the moisture content detection unit 18 after a predetermined time has elapsed (S110). The moisture content acquisition means 22 calculates the degree of transpiration of the measurement subject based on the difference between the moisture content in the sealed space forming member 162 and the starting moisture content. Here, an example of calculating the degree of transpiration will be described with reference to FIG. The degree of transpiration is, for example, as shown in FIG. 7, where the area 95 of the living body 90 covered with the sealed space forming member 162 is A, and the amount of moisture evaporated within the sealed space forming member 162 within a predetermined time is S. Is represented by S / A. As described above, the transpiration degree measuring unit 16 measures the transpiration degree. The evaluation index deriving unit 23 derives an evaluation index indicating the degree of the risk of developing heat stroke or dehydration based on either or both of the sensory temperature measurement and the degree of transpiration (S112).

  In the above description, the sensory temperature measurement, the transpiration degree measurement, and the evaluation index derivation process are described as being performed in the order of the sensory temperature measurement, the transpiration degree measurement, and the evaluation index derivation process. It is not something. That is, the measurement related to the sensory temperature, the measurement related to the transpiration degree, and the evaluation index derivation process may be performed, for example, in the order of the measurement related to the transpiration degree, the measurement related to the sensory temperature, and the evaluation index derivation process. Measurements relating to sensory temperature, measurement relating to transpiration degree may be performed independently, or measurements relating to sensory temperature, measurement relating to transpiration degree in various other order. Those subjected to the evaluation index derivation process are also included in the scope of the present invention.

  Next, a display mode indicating the degree of heat stroke or dehydration risk evaluated by the evaluation unit 20 will be described with reference to FIG. As described above, the evaluation index indicating the degree of heat stroke onset risk is either or both of the sensory temperature acquired by the sensory temperature acquisition unit 21 and the water content acquired by the water content acquisition unit 22. Derived based on one. The evaluation index indicating the degree of dehydration risk is the same as the evaluation index indicating the heat stroke risk. The display mode of the evaluation index indicating the degree of the onset risk of the heat stroke and dehydration thus derived includes various modes.

  As a display mode indicating the degree of the onset risk of heat stroke or dehydration evaluated by the evaluation unit 20, for example, a mode represented by a facial expression display 35 as shown in FIG. In this case, the evaluation index indicating the degree of heat stroke risk is divided into five levels. The face display 350 has, for example, a heat stroke onset risk of 0 to 20 (%), the face display 351 has, for example, a heat stroke onset risk of 20 to 40 (%), and the face display 352 has, for example, heat stroke onset. The risk is 40 to 60 (%), the face display 353 is, for example, the heat stroke onset risk is 60 to 80 (%), and the face display 354 is, for example, the heat stroke onset risk is 80 (%) or more.

  It should be noted that the display may be divided into five stages other than the face display. Moreover, although the above was a 5 step | level display, it is not limited to this, The display below 5 steps | paragraphs or the display of 5 steps | paragraphs or more may be sufficient.

  Moreover, as a display mode indicating the degree of the onset risk of heat stroke or dehydration evaluated by the evaluation unit 20, for example, a mode represented by a numerical ratio display as shown in FIG.

Next, a specific evaluation mode of an evaluation index indicating the degree of risk of developing heat stroke or dehydration will be described. The inventor of the present application conducted a test relating to temperature sensation using the biological risk evaluation apparatus 2. The starting temperature in the Peltier device was 36 ° C., and the temperature gradient was raised and lowered by 1 ° C. every 5 (seconds). The test subjects regarding the temperature sensation are male A in the early 40s, male B in the early 50s, and male C in the late 50s. The results are shown in Table 1. The heat recognition data in Table 1 represents the temperature related to the sensation that sensed a temperature change when it became hot, and the cold recognition data in Table 1 represents the temperature related to the sensation that felt a temperature change when it got cold.

  According to Table 1, it was 40.5 ° C. that the temperature change was felt when male A in the early 40s became hot. It was 43.3 ° C. that the temperature change was felt when male B in the early 50s became hot. It was 42.3 ° C when male C in the late 50s became aware of the temperature change. On the other hand, according to Table 1, it was 32.6 ° C. that the temperature change was felt when male A in the early 40s got cold. It was 30.3 ° C. that the temperature change was felt when male B in the early 50s got cold. It was 23.0 ° C. that the temperature change was felt when male C in the late 50s got cold.

  In general, it is said that when a person has a temperature higher than 43 ° C., the persistent warm sensation becomes a painful thermal sensation, and at a skin temperature of 15 ° C. or less, the persistent cold sensation becomes a painful cold sensation. Male B in his early 50s felt that the temperature change when he got hot was 43.3 ° C, and he felt the temperature change when he got hot at the temperature at which he felt a thermal pain sensation. It is done. Male C in his late 50s felt the temperature change when he got hot at 42.3 ° C, and he felt the temperature change when he got hot near the temperature at which he felt a thermal pain sensation. it is conceivable that. On the other hand, male A in the early 40s felt the temperature change when he got hot at 40.5 ° C., which is 2.5 ° C. or lower than the temperature at which he feels thermal pain. Therefore, male A in the early 40s is considered to have a warm sense within a normal range.

  Among temperature sensations, temperature sensation is considered to be particularly related to the risk of developing heat stroke. That is, if the sense of temperature is dull, there is a high possibility that the body temperature has risen when it is felt hot in a hot environment. If the sense of temperature is normal, measures such as cooling the body can be taken before the body temperature rises as described above. Therefore, it is considered that the degree of warm sense can be used as an element for determining the risk of developing heat stroke.

  Considering the above, male A in the early 40s is not at high risk of developing heat stroke, but male C in the late 50s and male B in the early 50s are considered to have a relatively high risk of developing heat stroke. . In particular, male C in his late 50s exceeds 43 ° C., which is a temperature related to thermal pain sensation, and attention is required regarding the onset of heat stroke.

  When the evaluation unit 20 performs the evaluation as described above, for example, the evaluation unit 20 learns the temperature related to the temperature sensation among the temperature sensations from the safe range to the dangerous range in five stages. Classify. For example, the temperature related to the sense of temperature is 40 ° C. or less (safe range), 40 ° C. to 40.5 ° C. (somewhat safe range), 40.5 ° C. to 41 ° C. (low risk range), 41 ° C. to 41.5 ° C. As an example, a division such as (range in the risk level), 42 ° C. or higher (range in the high risk level) is assumed. For example, the evaluation unit 20 derives an evaluation index indicating the degree of heat stroke onset risk by applying the temperature related to temperature sensation, which is a measurement result of the biological risk evaluation apparatus 2, to the above criteria.

  Also, looking at the cold recognition data in Table 1, it was 23.0 ° C that the temperature change was felt at 23.0 ° C in the early 50s male B, compared to male A in the early 40s and male C in the late 50s. Is also particularly low. For this reason, it is considered that the temperature sensation of male B in the early 50s is duller than that of male C in the late 50s when temperature sensation and cold sensation are combined. Therefore, the male B in the early 50s has a lower temperature sensation than the male C in the late 50s, and therefore, for example, the risk of developing heat stroke may be determined to be higher than the male C in the late 50s.

  As described above, the evaluation index indicating the degree of heat stroke onset risk based on the thermal recognition data on the temperature related to the temperature sense may be corrected using the cold recognition data on the temperature related to the cold sense. According to this, it is possible to derive an evaluation index indicating the degree of heat stroke onset risk using both the heat recognition data related to the temperature related to the temperature perception in Table 1 and the cold recognition data related to the temperature related to the cold perception in Table 1. .

  Furthermore, heat stroke is said to be a factor in the onset of increased body temperature due to dehydration. Here, if the degree of transpiration is measured by the transpiration degree measurement unit of the present invention and data on the degree of transpiration is further added, it is considered that the evaluation index indicating the degree of heat stroke risk can be comprehensively determined. . That is, if the degree of transpiration is large, it can be corrected to increase the risk of developing heat stroke, and if the degree of transpiration is small, it can be corrected to decrease the risk of developing heat stroke.

  Next, dehydration will be described. Dehydration is caused by a lack of water intake relative to water loss. Data regarding the degree of transpiration is important in determining the risk of developing dehydration, and the risk of developing dehydration can be determined based on the data regarding the degree of transpiration. That is, when the degree of transpiration is large, it is considered that the amount of water loss of the measurement subject is large, so the degree of risk of dehydration is large. On the other hand, if the degree of transpiration is small, it is considered that the amount of water loss of the measurement subject is small, so the degree of risk of dehydration is small.

  When the evaluation unit 20 performs the evaluation as described above, for example, the transpiration degree is classified into five levels from a safe range to a dangerous range according to the above description of classification into five levels of temperature sensation regarding the evaluation unit 20. To do. For example, the evaluation unit 20 derives an evaluation index indicating the degree of dehydration risk by applying the transpiration degree, which is a measurement result of the transpiration degree measurement unit, to the above five-stage criteria.

  Further, in the determination of the degree of risk of developing dehydration, heat recognition data on the temperature related to the above temperature sense and cold recognition data on the temperature related to the cold sense may be included. For example, if the sense of temperature is dull, the outside temperature may be hot, but it may not feel hot. Even in this case, the body temperature rises, but sweating proceeds because appropriate measures such as cooling the body cannot be taken. As a result, the amount of water loss increases. The mechanism as described above may cause dehydration. Therefore, it is useful to make corrections in consideration of the thermal recognition data related to the above-mentioned temperature sensation in the determination of the risk of developing dehydration. It is also useful to make corrections as described above using cold recognition data on the temperature related to cold sensation in determining the risk of developing dehydration.

  In addition, the determination of the degree of heat stroke or dehydration risk may be made based on the heat recognition data related to temperature sensation, the cold recognition data related to temperature related to cold sensation, and the degree of transpiration. You may carry out based on any one or the combination of two. Moreover, the classification into the five levels of the temperature related to the temperature sensation and the cold sensation in the temperature sensation and the classification into the five levels of the transpiration degree are examples, and may be further subdivided. It may be a mode of classification.

  In addition, in the above, the biological risk evaluation apparatus includes a part related to temperature sensation (temperature sensation measurement unit, temperature setting unit, temperature gradient setting unit, sensory temperature acquisition unit), and a part related to transpiration degree (transpiration degree measurement unit, moisture content acquisition). However, the present invention is not limited to such a configuration. That is, the biological risk evaluation apparatus may be configured to include any one of a part related to temperature sensation and a part related to the degree of transpiration. In addition, the measurement start temperature, the upper limit temperature of the temperature change, the lower limit temperature of the temperature change, and the temperature gradient use fixed values, and the temperature setting unit and the temperature gradient setting unit are omitted in the biological risk evaluation apparatus among the parts related to the temperature sensation. May be.

  Next, the biological risk evaluation apparatus 3 will be described with reference to FIGS. The biological risk evaluation apparatus 3 has a configuration similar to that of the biological risk evaluation apparatus 1, and the same name and code are used for those having similar functions. As shown in FIG. 9, the difference between the two is the function of the temperature sensation measurement units 11 and 100 and the function of the evaluation units 20 and 24 corresponding thereto. In addition, a body temperature measurement unit 120 is added to the measurement unit 10 a of the biological risk evaluation apparatus 3. Hereinafter, the above points will be mainly described.

  Similar to the temperature sensation measurement unit 11, the temperature sensation measurement unit 100 in the biological risk evaluation apparatus 3 measures the temperature sensation of the living body. For example, the heat donation unit 101, the temperature detection unit 103, and the sensory action detection are performed. Unit 104 and temperature sensation measurement control unit 110.

  The heat donating unit 101 gives warm or cold heat to a predetermined part of the living body, and has a constant temperature donating unit 102. The constant temperature donating unit 102 continuously gives a substantially constant temperature to a predetermined part of the living body. The substantially constant temperature is given to a predetermined part of the living body by the constant temperature providing unit 102 for a predetermined time.

  In the heat donating unit 101, a temperature change unit (not shown) changes the temperature of a predetermined part of the living body to a predetermined temperature, and then the constant temperature donating unit 102 supplies a substantially constant temperature to the predetermined part of the living body. Is given for a predetermined time. Note that the substantially constant temperature does not have to be a strict constant temperature, and may vary somewhat. Moreover, as for predetermined time, 1 minute is mentioned as an example, for example.

  The heat donating unit 101 has a heat radiating member (not shown) at a portion that comes into contact with a predetermined part of the living body. Hot or cold heat is emitted through the heat dissipation member. When heat is emitted through the heat radiating member, a predetermined part of the living body that contacts the heat radiating member is heated. When cold heat is emitted through the heat radiating member, a predetermined part of the living body that contacts the heat radiating member is cooled.

  For example, as shown in FIG. 10, the heat donating unit 101 determines a predetermined amount of the living body by a temperature changing unit from the start of measurement of the temperature sensation of the living body (0 seconds) to about 42 degrees (not shown) in about 10 to 15 seconds. Then, a temperature change is applied to this part, and thereafter, a constant temperature state at about 40 degrees is continuously applied to a predetermined part of the living body by the constant temperature supply unit 102 for one minute. Further, the heat donating unit 101 changes the temperature of a predetermined part of the living body by a temperature changing unit (not shown) from about 10 to 15 seconds from the start of measurement of the temperature sensation of the living body to about 20 degrees (not shown). After that, the constant temperature supply unit 102 operates to continuously give a predetermined temperature of about 20 degrees to a predetermined part of the living body for 30 seconds. The above operation of the heat donating unit 101 is an example, and the time and temperature may be other values.

  An example of the heat supply unit 101 is a temperature transmission mechanism using a Peltier element. An example of the temperature transmission mechanism is a mechanism in which a radiating fin and a heater are brought into contact with one side of the Peltier element and a radiating member is brought into contact with the other side of the Peltier element. The heat transfer direction of the Peltier element is controlled by the Peltier element control unit. When warm heat is generated from the heat dissipation member, the heater is turned on, and the heat of the heater is transferred to the heat dissipation member through the Peltier element. When cold heat is generated from the heat radiating member, the heater is turned off, and the heat of the heat radiating member is transferred to the heat radiating fin through the Peltier element.

  The temperature detection unit 103 detects a temperature at or near a predetermined part of the living body to which heat or cold is given by the heat donating unit 101, or a temperature at or near a predetermined part (for example, a heat radiating member) of the heat donating unit 101. It is to detect. In the following, a predetermined part of the living body to which warm heat or cold is given by the heat donating unit 101 or the vicinity thereof will be referred to as “predetermined part of the living body”. In addition, a predetermined portion (for example, a heat radiating member) of the heat donating unit 101 or the vicinity thereof is referred to as a “heat radiating member or the like”. Examples of the temperature detection unit 103 include a temperature sensor using a thermistor and the like. However, the temperature detection unit 103 is not limited to this, and may be one that can detect other temperatures.

  The sensory action detection unit 104 is the same as the sensory action detection unit 14, but is preferably configured by a spontaneous pressing type switch that is spontaneously pressed to detect a sensory action. In the biological risk evaluation apparatus 3, a substantially constant temperature is continuously given to a predetermined part of the measurement subject. Then, in the biological risk evaluation apparatus 3, when the spontaneous pressing switch is spontaneously pressed in the process of reaching a substantially constant temperature or immediately after reaching the substantially constant temperature, the temperature sensation of the measurement subject is Treated as normal. On the other hand, in the biological risk evaluation apparatus 3, if the spontaneous pressing switch is not yet pressed even after elapse of, for example, 40 seconds after reaching a substantially constant temperature, the temperature sensation of the measurement subject is treated as not normal.

  In this way, in the biological risk evaluation apparatus 3, since the temperature sensation of the measurement subject is evaluated at the timing when the switch is pressed, the sensory motion detection unit 104 immediately senses the temperature change as the sensory motion detection unit 104. Spontaneous push-type switches that can transmit are preferred. Among the experiments of the inventor, it is clear that the voluntary push-type switch is more likely to transmit the sensory action immediately after the subject of measurement senses the temperature change than the push switch in the biological risk assessment devices 1 and 2. there were. For this reason, it is preferable that the sensory action detection unit 104 is configured by a spontaneous pressing switch that is spontaneously pressed to detect a sensory action.

  The temperature sensation measurement control unit 110 will be described with reference to FIG. The temperature sensation measurement control unit 110 controls measurement related to the temperature sensation of a living body, and includes, for example, a temperature determination unit 111, a temperature adjustment unit 112, and a measurement mode selection unit 113.

  The temperature determination unit 111 has a temperature detected by the temperature detection unit 103 (hereinafter referred to as a detection temperature) after the measurement of the temperature sensation of the living body is equal to or higher than the upper threshold temperature or lower than the lower threshold temperature. It is to determine whether there is. The temperature determination unit 111 is preferably configured to determine the temperature of the heat dissipation member or the like. Accordingly, a temperature detecting unit such as a heat radiating member (not shown) for detecting the temperature of the heat radiating member or the like is separately provided, and the temperature determination unit 111 performs the determination as described above based on the temperature detected by the temperature detecting unit such as the heat radiating member. You may go.

  When the temperature determination unit 111 determines that the detected temperature is equal to or higher than the upper limit threshold temperature, the temperature adjustment unit 112 cools the heat dissipation member 101a and the like to a predetermined temperature. Further, when the temperature determination unit 111 determines that the detected temperature is equal to or lower than the lower limit threshold temperature, the temperature adjustment unit 112 heats the heat dissipation member 101a and the like to a predetermined temperature. The temperature adjustment unit 112 is configured by any combination of a cooling fan, a heat radiation fin, a heater, and the like, for example. As the predetermined temperature, for example, the normal temperature of the measurement target portion of the measurement target person is given as an example. The temperature of the measurement target part of the measurement subject can be measured by a body temperature measurement unit 120 described later. In addition, the temperature of the measurement target portion of the measurement target person may be set in advance to be, for example, 36.5 degrees, 30 degrees, or the like.

  If comprised as mentioned above, since the temperature of the heat radiating member 101a etc. can be made into the normal temperature of a measurement object part of a measurement subject after completion of measurement of a measurement subject's temperature sense, the next temperature sense Measurement can be started quickly.

  The measurement mode selection unit 113 accepts and sets a selection of a temperature measurement mode that is a measurement mode of a temperature sensation related to a temperature sensation or a cold sense measurement mode that is a measurement mode of a temperature sensation related to a cold sensation. The heat donating unit 101 operates to give a temperature state corresponding to the measurement mode accepted by the measurement mode selection unit 113 to a predetermined part of the living body. The temperature state corresponding to the temperature measurement mode is, for example, a temperature in the vicinity of the target temperature with respect to the predetermined part of the living body after a temperature change is given to the predetermined part of the living body to be raised to the target temperature. It refers to a state in which a certain state is continuously given for a predetermined time. The temperature state according to the cold sense measurement mode is, for example, a temperature change that is lowered to a target temperature with respect to a predetermined part of the living body, and then the vicinity of the target temperature with respect to the predetermined part of the living body. The state in which a constant temperature state is continuously applied for a predetermined time.

  Further, the continuous measurement mode may be added to the selection target of the measurement mode selection unit 113. The continuous measurement mode refers to a mode in which a temperature sensation relating to cold sensation and a temperature sensation relating to warm sensation are continuously measured. In this case, the heat donating unit 101 operates so as to apply a temperature state corresponding to the continuous measurement mode to a predetermined part of the living body.

  Moreover, in the biological risk evaluation apparatus 3, as shown in FIG. 9, a body temperature measurement unit 120 is added to the measurement unit 10a. The body temperature measuring unit 120 measures the temperature (body temperature) of a predetermined part of the living body. The body temperature measurement unit 120 may be configured to include the correction unit 121.

  The correction unit 121 corrects the temperature of a predetermined part of the living body. In general, body temperature is measured in the armpit or mouth, and the latter half of 35 degrees to the latter half of 36 degrees is recognized as a normal body temperature. And body temperature changes with the site | parts of a biological body, for example, when body temperature is measured with a forearm, it will be 30 degree | times with normal body temperature. In order to match such body temperature with general body temperature recognition, the correction unit 121 is required. The body temperature may be a deep body temperature. The corrected body temperature is displayed on the display unit 30. The body temperature measurement unit 120 may be replaced with the temperature detection unit 13.

  The evaluation unit 24 in the biological risk evaluation apparatus 3 evaluates the risk of developing heat stroke or dehydration based on at least one of the temperature sensation and the degree of transpiration of the living body. Measuring means 26, body temperature acquisition means 27, water content acquisition means 28, and evaluation index derivation means 29 are provided.

  The sensory temperature acquisition unit 25 acquires the temperature detected by the temperature detector 103 when the sensory action detector 104 detects a sensory action as the sensory temperature. The time measuring unit 26 measures an elapsed time until the sensory action detection unit 104 detects a sensory action. As the starting point of the elapsed time, for example, when a measurement of the temperature sensation of the living body is started, when provision of a substantially constant temperature to the living body is started, or after a predetermined time has elapsed from the start of the measurement of the temperature sensation of the living body. The body temperature acquisition means 27 acquires the temperature of a predetermined part of the living body that is measured by the body temperature measurement unit 120 when the sensory action detection unit 104 detects a sensory action. The moisture content acquisition means 28 acquires the moisture content detected by the moisture content detector 18.

  The evaluation index deriving unit 29 derives an evaluation index indicating the degree of the onset risk of heat stroke or dehydration. The evaluation index deriving unit 29 derives the evaluation index indicating the degree of the onset risk of heat stroke or dehydration. 25, the elapsed time measured by the time measuring unit 26, the temperature of a predetermined part of the living body acquired by the body temperature acquiring unit 27, and the moisture amount acquired by the moisture amount acquiring unit 28. Based on at least one.

  Note that the evaluation index may be derived based on any of the above information. For example, the evaluation index is derived only from the sensory temperature, only the elapsed time, only the water content, only the sensory temperature and the elapsed time, only the sensory temperature and the water content, and only the elapsed time and the water content. May be. Then, the evaluation index may be derived by combining the above information with the temperature of a predetermined part of the living body acquired by the body temperature acquisition unit 27.

  Next, the biological risk evaluation apparatus 4 will be described with reference to FIGS. The biological risk evaluation apparatus 4 has the same internal functional blocks as the biological risk evaluation apparatus 3. In addition, since the thing similar to the biological risk evaluation apparatus 3 attaches | subjects the same code | symbol and has already demonstrated about them, the description is abbreviate | omitted. The biological risk evaluation apparatus 4 includes a measurement unit 10a including a temperature sensation measurement unit 100, a transpiration degree measurement unit 16, and a body temperature measurement unit 120, an evaluation unit 20, a display unit 130, and a holding unit 140.

  The heat donating unit 101 in the temperature sensation measuring unit 100 is configured by, for example, a Peltier element temperature transmission mechanism. The heat supply unit 101 is accommodated in a casing 141 described later. And the heat radiating member 101a in the Peltier element temperature transmission mechanism is disposed so as to slightly protrude from the ceiling surface 144 of the housing 141. The temperature detection unit 103 in the temperature sensation measurement unit 100 is not shown because it is housed inside the housing 141.

  The sensory action detection unit 104 in the temperature sensation measurement unit 100 is configured by a spontaneous pressing type switch, unlike the pressing switch in the biological risk evaluation apparatus 2. The spontaneous pressing switch constituting the sensory action detection unit 104 is disposed on the ceiling surface 146 of the casing 142 described later.

  The body temperature measurement unit 120 may be either a contact type or a non-contact type. The body temperature measurement unit 120 is housed in the housing 141. In the case of the contact-type body temperature measurement unit 120, the body temperature measurement unit 120 is arranged such that a portion that comes into contact with its own living body slightly protrudes from the ceiling surface 144 of the housing 141. In the case of the non-contact type body temperature measuring unit 120, the body temperature measuring unit 120 is arranged so that infrared light emitted from the living body can be received by its own light receiving unit (not shown) through the hole 144 a of the ceiling surface 144 of the housing 141. .

  As shown in FIGS. 13A and 13B, the transpiration degree measurement unit 16 includes a covering unit 17 and a water content detection unit 18 as in the biological risk evaluation apparatus 1. The covering portion 17 is configured by a sealed space forming member 170. The sealed space forming member 170 has an opening 171. When the opening 171 is closed, the inside is substantially sealed. That is, when the opening 171 is brought into contact with a predetermined part of the living body, the sealed space forming member 170 covers the predetermined part of the living body in a substantially sealed state. Specifically, in the biological risk evaluation apparatus 4, the sealed space forming member 170 is constituted by, for example, a cup-shaped container member having an opening. The material of the sealed space forming member 170 is preferably a soft resin. An example of the soft resin is silicon rubber. The moisture amount detection unit 18 is the same as that described above and has already been described.

  The display unit 130 is substantially the same as the display unit 30 in the biological risk evaluation apparatus 2 shown in FIG. 2, and is provided so as to be visible from the ceiling surface 146 side of the housing 142.

  As shown in FIG. 12 (a), the holding unit 140 includes the temperature sensation measurement unit 100 and the transpiration degree measurement unit 16 so that the temperature sensation measurement unit 100 and the transpiration degree measurement unit 16 constituting the measurement unit 10a face each other. And hold. Hereinafter, a direction in which the temperature sensation measurement unit 100 and the transpiration degree measurement unit 16 are opposed to each other is referred to as an opposing direction (see arrow A). And the holding | maintenance part 140 is comprised by the housing | casing 141,142, the rocking | swiveling mechanism 150, and the relative movement mechanism 160, as shown to Fig.12 (a).

  The housing 141 accommodates and holds the temperature sensation measurement unit 100. And the housing | casing 141 functions as a support stand which supports the biological risk evaluation apparatus 4 whole. Specifically, the housing 141 is formed in, for example, a hollow substantially cylindrical shape, and one bottom surface forms the installation surface 143 and the other bottom surface forms the ceiling surface 144. Note that the housing 141 may have other shapes.

  Further, as shown in FIGS. 14A and 14B, a living body part (for example, the rear forearm portion 190) is placed on the ceiling surface 144 of the housing 141. The ceiling surface 144 is slightly curved so as to be recessed toward the installation surface 143 so that a living body part can be easily placed. Hereinafter, description will be made assuming that the rear forearm portion 190 is placed on the ceiling surface 144 of the housing 141.

  In addition, when the rear forearm portion 190 is placed on the ceiling surface 144, a predetermined portion (the heat radiating member 101 a) of the heat donating portion 101 is arranged from the ceiling surface 144 so that the rear forearm portion 190 can come into contact with the heat donating portion 101. It is arranged to protrude in the out-of-plane direction. Accordingly, when the rear forearm 190 is placed on the ceiling surface 144, the rear forearm 190 comes into contact with a predetermined portion (the heat radiation member 101a) of the heat donating unit 101.

  Returning again to FIG. The housing 142 accommodates and holds at least a part of the transpiration degree measurement unit 16. Further, the swing mechanism 150 is accommodated in the housing 142. As shown in FIGS. 12 and 13, the swing mechanism 150 has an axis F (refer to a one-dot chain line) in which the opening 171 faces the temperature sensation measuring unit 100 and extends in the facing direction and passes through the sealed space forming member 170. The sealed space forming member 170 is held in a state where the sealed space forming member 170 can be swung with an axis extending in a direction perpendicular to the swivel axis. Specifically, for example, as shown in FIG. 13, the sealed space forming member 170 has an axis G extending in a direction perpendicular to the axis F (an axis extending in a direction perpendicular to the paper surface) as an oscillation axis, It is held so that it can swing. The axis F is preferably a central axis extending in the depth direction of the sealed space forming member 170.

  There are various swing modes of the sealed space forming member 170. For example, the sealed space forming member 170 may be configured to have a plurality of swing shafts extending in a direction perpendicular to the axis F. In this case, the sealed space forming member 170 can swing in a plurality of directions.

  Further, the housing 142 has, for example, a hollow, substantially L-shaped shape as shown in FIGS. And the housing | casing 142 has the opening 142a in the substantially L-shaped end surface by the side of the temperature sense measurement part 100 of an opposing direction.

  Further, as shown in FIG. 13, the housing 142 is provided with an opening 145 at a position facing the ceiling surface 144. The sealed space forming member 170 protrudes from the opening 145 toward the temperature sensation measuring unit 100 in the facing direction, and is held so that its own opening 171 faces the ceiling surface 144.

  The relative movement mechanism 160 relatively moves the temperature sensation measurement unit 100 or the transpiration degree measurement unit 16 in the facing direction (see arrow A in FIG. 12A). Specifically, the housing 141 or the housing 142 is relatively moved in the facing direction by the relative movement mechanism 160. The relative movement mechanism 160 includes a relative movement restriction mechanism 161 and a restriction release mechanism 167.

  The relative movement restriction mechanism 161 allows the temperature sensation measurement unit 100 and the transpiration degree measurement unit 16 to move toward each other along the facing direction, and restricts the movement away from each other. For example, as shown in FIG. 12A, the relative movement restriction mechanism 161 includes a guide column 168 and a one-way movement restriction mechanism 164. The guide column 168 is connected to the housing 141 and extends toward the transpiration degree measuring unit 16 in the facing direction. A guide column 168 is inserted into the housing 142 through the opening 142a. The housing 142 is guided by the guide column 168 and is slidable in the opposite direction.

  The one-way movement restriction mechanism 164 allows the casing 142 to slide in the insertion direction side in the opposite direction along the guide column 168 and slides the casing 142 in the opposite direction to the insertion direction side in the opposite direction. It is a limitation. For example, as shown in FIG. 12B, the one-way movement restricting mechanism 164 includes a pair of guide rails 164b having a latch 164a having serrated irregularities, and engages with the latch 164a to move on the guide rail 164b. It can be configured by a sliding movable engaging member 164c.

  The latch 164a allows sliding movement of the engaging member 164c to one side in the length direction of the guide rail 164b (see arrow C), and allows sliding movement of the engaging member 164c to the other side in the length direction of the guide rail 164b. It has a sawtooth shape to limit. The engaging member 164c is connected to the guide column 168, for example. Further, the pair of guide rails 164b is coupled to the housing 142, for example.

  The restriction release mechanism 167 releases the restriction on the movement of the temperature sensation measurement unit 100 and the transpiration degree measurement unit 16 away from each other along the facing direction. When the restriction is released by the restriction release mechanism 167, the temperature sensation measurement unit 100 and the transpiration degree measurement unit 16 are allowed to move away from each other along the facing direction. As a restriction release mechanism 167 corresponding to the one-way movement restriction mechanism 164, for example, as shown in FIG. 12B, the guide rail 164b is perpendicular to the facing direction so that the latch 164a and the engagement member 164c are disengaged. A mechanism for moving in the direction (see arrow B) can be used.

  Next, a specific operation of the relative movement mechanism 160 will be described with reference to FIG. Assume that the rear forearm portion 190 is placed on the ceiling surface 144 of the housing 141 as the measurement subject's site, as shown in FIG. At this time, the rear forearm portion 190 contacts the heat radiating member 101 a of the heat donating portion 101. Further, when the casing 142 is moved toward the forearm 191 by the relative movement mechanism 160, the opening 171 of the sealed space forming member 170 comes into contact with the forearm 191 as shown in FIG. The opening 171 is closed by the forearm 191. Thereby, the inside of the sealed space forming member 170 is substantially sealed.

  As a result, the forearm 192 is sandwiched between the sealed space forming member 170 and the heat donating part 101 as shown in FIG. In such a state, the sensory temperature can be measured and the transpiration degree can be measured. In the biological risk evaluation apparatus 2, the state in which the sensory temperature can be measured and the state in which the transpiration degree can be measured are configured separately. However, in the biological risk evaluation apparatus 4, the state in which the sensory temperature can be measured and the transpiration degree are configured. The measurable state is integrally formed. As a result, the biological risk evaluation device 4 is less labor-intensive for measurement than the biological risk evaluation device 2.

Next, an example of the operation of the biological risk evaluation apparatuses 3 and 4 will be described with reference to FIGS. Assume that the rear forearm portion 190 is placed on the ceiling surface 144 of the housing 141 as the measurement subject's site, as shown in FIG. The housing 142 is moved to the forearm 191 by the relative movement mechanism 160. As a result, the forearm portion 192 of the measurement subject is sandwiched between the temperature sensation measurement unit 100 and the transpiration degree measurement unit 16. From this state, when the measurement start button 134 (see FIG. 12A) is pressed, measurement of the sensory temperature is started.

  When measurement of the sensory temperature is started, time measurement is started by the time measuring means 26 (S201). At the same time, a temperature change is given to the measurement subject's forearm 192 by a temperature change unit (not shown) (S202). In the process of temperature change, sensory motion detection unit 104 detects sensory motion (S203). For example, when a switch constituting the sensory action detection unit 104 is pressed, a sensory action is detected.

  Until the sensory motion is detected, the heat donating unit 101 continuously gives a temperature change to the measurement subject's forearm 192 by a temperature changing unit (not shown) toward the target temperature (S204). Examples of the target temperature include 40 degrees and 25 degrees. When the temperature given to the measurement subject's forearm 192 reaches the target temperature, the constant temperature providing unit 102 continuously gives a constant temperature to the living body (S204).

  When the sensory action is detected, the sensory temperature acquisition unit 25 acquires the temperature of the heat radiating member or the like (or the predetermined part of the living body) at the time of detection from the temperature detection unit 103 (S205). Further, when the sensory action is detected, the time measuring means 26 ends the time measurement at the time of detection (S206). When the sensory movement is detected, the body temperature acquisition unit 27 acquires the temperature of the rear forearm 190 of the measurement subject from the body temperature measurement unit 120 at the time of detection (S207).

  Note that the start of time measurement by the time measurement means 26 is not limited to step S201. For example, the time measurement by the time measuring means 26 starts after the heat supply unit 101 reaches the target temperature and the constant temperature supply unit 102 starts supplying a constant temperature to the rear forearm 190 of the measurement subject. It may be done.

  Next, a sweating amount measurement process is performed (S208). Note that the sweating amount measurement processing refers to processing from steps S108 to S111 in FIG. Since this has already been described, the description thereof is omitted.

  When the above processing is completed, the evaluation index deriving unit 29 measures the temperature of the heat radiating member or the like (or a predetermined part of the living body) when detecting the sensory action, the elapsed time until detection of the sensory action, and the body temperature when detecting the sensory action. An evaluation index indicating the degree of the onset risk of heat stroke or dehydration is derived based on either the temperature measured by the unit 120 and the degree of transpiration (S209).

  In addition, although the process regarding the temperature sensation in steps S201 to S207 and the sweating amount measurement process in step S208 are performed in the above order, the process is not limited to this, and the order may be reversed. Further, the process related to the temperature sensation and the sweating amount measurement process may be performed simultaneously.

  Next, the derivation of the evaluation index based on the temperature sensation will be described with reference to FIG. For example, when the measurement of the sensory temperature related to the sense of temperature is started, the temperature of the heat donating unit 101 rises. At this time, if a sensory action is detected between the elapsed time T and 0 to T1 (s), it is determined that the sense of temperature is abnormal. In addition, it is because the temperature of the heat | fever donation part 101 is below about 37.3 degree | times at 0-T1 (s).

  When a sensory action is detected when the elapsed time T is between T1 and T2 (s), it is determined that the sense of temperature is normal. This is because the temperature of the heat donating unit 101 is approximately 37.3 to 42 degrees at T1 to T2 (s).

  When sensory motion is detected between the elapsed time T and 0 to T2 (s), the time elapsed until detection of sensory motion is calculated in order to derive an evaluation index indicating the degree of onset risk of heat stroke or dehydration. It does not have to be referenced.

  When a sensory action is detected when the elapsed time T is between T2 and T3 (s), it is determined that the sense of temperature is abnormal as time elapses from T2. This is because at the time of T2 to T3 (s), the temperature of the heat donating unit 101 is about 40 degrees, and if the temperature sensation is normal, the sensory action should be detected as soon as it feels hot.

  As described above, an evaluation index indicating the degree of risk of developing heat stroke or dehydration is determined according to the state of warm sensation. The determination regarding the state of the sense of temperature includes not only the temperature of the heat donating unit 101 and the elapsed time until the sensory action is detected, but also the temperature (body temperature) of a predetermined part of the living body measured by the body temperature measuring unit 120. May be considered. For example, when a person having a body temperature higher than that of a normal person is a measurement subject, the temperature felt to be hot is considered to be higher than that of a normal person. Conversely, when a person having a lower body temperature than a normal person is a measurement subject, the temperature felt hot is considered to be lower than that of a normal person. In this case, it is preferable that an evaluation index indicating the state of warm sensation and the risk of developing heat stroke or dehydration be determined in consideration of this.

  Next, with reference to FIG. 17, the flow of processing at the end of measurement of the temperature sensation of the living body will be described. When the measurement of the temperature sensation of the living body is completed (S301), the temperature determination unit 111 next determines the temperature of the heat dissipation member and the like. The temperature of the heat radiating member and the like is detected by the temperature detection unit 103.

  In the temperature determination unit 111, it is determined whether or not the temperature of the heat radiating member is equal to or higher than an upper limit threshold (S302). When it is determined that the temperature of the heat radiating member is equal to or higher than the upper limit threshold, the heat radiating member or the like is cooled to a predetermined temperature by the temperature adjustment unit 112 (S303).

  If it is determined that the temperature of the heat radiating member is equal to or lower than the upper limit threshold, the temperature determination unit 111 determines whether the temperature of the heat radiating member is equal to or lower than the lower limit threshold (S304). When it is determined that the temperature of the heat radiating member or the like is equal to or lower than the lower limit threshold, the heat radiating member or the like is heated to a predetermined temperature by the temperature adjusting unit 112 (S305).

  Next, the biological risk evaluation apparatus 5 will be described with reference to FIGS. In addition, in the biological risk evaluation apparatus 5, the thing similar to the biological risk evaluation apparatuses 1-4 is attached | subjected the same code | symbol, and since it has already demonstrated about them, the description is abbreviate | omitted.

  The biological risk evaluation apparatus 5 is configured based on the transpiration degree measurement unit 16 in the biological risk evaluation apparatus 2 shown in FIGS. In the biological risk evaluation apparatus 5, the portion corresponding to the holding movable member 169 in the transpiration degree measurement unit 16 is replaced with a casing 169a that houses the temperature sensation measurement unit 100 (or the temperature sensation measurement unit 11), as shown in FIG. It is done. In the biological risk evaluation apparatus 5, control circuits constituting the evaluation units 20 and 24 (not shown) are accommodated in the housing 166 a constituting the clamping member 166. Further, as shown in FIG. 18, the display units 30 and 130 in the biological risk evaluation apparatus 5 are arranged in the housing 166a so as to be visible from the outside of the housing 166a. The biological risk evaluation apparatus 5 may be driven by an external power source or may be driven by an internal power source such as a battery housed inside.

  If the biological risk evaluation apparatus 5 is configured as described above, the biological risk evaluation apparatus 5 can be configured more compactly than the biological risk evaluation apparatuses 2 and 4.

    In addition, the biological risk evaluation apparatus of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.
