Description

Technical Field

[0001] The invention relates to a temperature continuity detector and a heat stroke detector. Background Art

[0002] A heat stroke warning sticker has been proposed, in which a part of the material becomes transparent when the temperature reaches a predetermined temperature or higher, so that a "warning display" of the underlying layer can be visually recognized (see Patent Document 1). In addition, these constitute a part of this specification by reference.

[0004] Patent Literature

[0005] Patent Document 1: Patent Publication No. 2018-179685 Summary of the invention

[0006] Problems to be solved by the invention

[0007] Generally speaking, regarding the mechanism of heat stroke, it is important to detect that the deep body temperature has become higher than a specified temperature. Therefore, heat stroke cannot be immediately determined just because the surface temperature temporarily or instantly becomes higher than a specified temperature. Therefore, the heat stroke warning sticker described in Patent Document 1 is insufficient as a method for accurately determining whether heat stroke has occurred.

[0008] In addition, the heat stroke warning sticker described in Patent Document 1 will also display a "warning display" when the temperature exceeds the detection temperature for a moment due to temporary and accidental reasons (for example, temporarily being near a certain heat source, temporarily entering or passing through a space with a high temperature, etc.). Moreover, it is impossible to confirm that the "warning display" is a false detection (for example, a "warning display" appears when you are temporarily near a certain heat source, but it is judged to be a temporary false detection. However, if you have entered a state of heat stroke before this, your perception and the actual state of the organism are different, which is dangerous).

[0009] This not only makes it impossible to make an accurate determination due to the nature of the product, but also causes a problem in that it is difficult to confirm that an erroneous detection has occurred from the viewpoint of safety.

[0010] Therefore, an object of the present invention is to solve this problem.

[0011] Means for solving problems

[0012] According to the present invention, a temperature continuity detector can be obtained, which detects at least one of the following situations: the situation where the fever detection object is at a predetermined temperature for a predetermined time, or the temperature above the predetermined temperature for a predetermined time, wherein:

[0013] The temperature continuity detector includes a sensor unit having a temperature-sensitive material that undergoes a predetermined change in response to the predetermined temperature and a heat-conductive material that conducts the heat generated by the detection object to the temperature-sensitive material over the predetermined time.

[0014] In addition, according to the present invention, a heat stroke detector can be obtained, which detects at least one of the following situations: a situation where a biological body is at a predetermined temperature for a predetermined time, or a temperature above the predetermined temperature for a predetermined time, wherein:

[0015] The heat stroke detector includes a sensor unit having a temperature-sensitive material that undergoes a predetermined change in response to a temperature equal to or higher than the predetermined temperature, and a heat-conductive material that conducts the heat generated by the living body to the temperature-sensitive material over the predetermined time.

[0082] <Details of Implementation Method>

[0083] Hereinafter, the structure of the heat stroke detector as an embodiment of the temperature continuity detector of the present invention will be described with reference to the accompanying drawings. In addition, in order to prevent repeated description, the same or related reference numerals are sometimes marked on the same components and detailed description is omitted.

[0084] <Summary>

[0085] The heat stroke detector of the embodiment of the present invention detects at least one of the following situations: the temperature of the wearing part of the body is a predetermined temperature for a predetermined time, or the temperature is above the predetermined temperature for a predetermined time. In other words, it detects that the temperature of the wearing part is maintained within the temperature range above the predetermined temperature for a predetermined time (in other words, the temperature of the wearing part does not become below the predetermined temperature within the predetermined time).

[0086] Generally, in order to detect heat stroke, it is necessary to detect that the deep body temperature is higher than a predetermined temperature for a predetermined time. However, it is not realistic to continuously insert a temperature sensor deep into a living body.

[0087] On the other hand, it is inaccurate to regard the body surface temperature, which is easily changed by the influence of the external environment, as the temperature of the deep body temperature. Therefore, the heat stroke detector of this embodiment detects the situation that the temperature of the wearing part of the body is a specified temperature for a specified time. In this way, it is possible to accurately detect whether the person wearing the heat stroke detector has heat stroke. That is, the heat stroke detector of this embodiment does not detect and notify the user that the body surface has reached a certain temperature, but detects and notifies the user when the body surface temperature reaches a certain temperature or a specified time has passed after it has reached a certain temperature or above.

[0088] In order to realize such a viewpoint, the heat stroke detector of this embodiment is configured to provide an intermediate material between the contact part that contacts the skin and the temperature sensing part. According to such a structure, the skin temperature (body surface temperature) takes a predetermined time to pass through the intermediate material and be transmitted to the temperature sensing part, so at least it can be detected that the skin temperature is a predetermined temperature within a predetermined time when the temperature sensing material responds.

[0089] In addition, existing technologies may also issue a notification when a certain temperature is reached instantly, and will also detect situations with a low risk of heat stroke.

[0090] <Structure>

[0091] (First Embodiment)

[0092] like Figure 1 As shown, the heat stroke detector 10 of this embodiment is configured to be wearable on the wrist of the user. The heat stroke detector 10 includes a sensor unit 100 and is worn on the wrist via a fixing unit 400 .

[0093] Reference Figure 1 and Figure 2 , the structure of the heat stroke detector 10 of this embodiment will be described in more detail. Figure 2 Observed from the direction of P Figure 1 The cross-sectional view of the heat stroke detector 10 is shown in FIG. Figure 2 As shown, the heat stroke detector 10 includes a sensor unit 100, a heat insulating unit 300, and a fixing unit.

[0094] The sensor unit 100 includes: a temperature-sensitive material 110 that undergoes a specified change in response to a specified temperature; a heat-conductive material 120 that transfers the temperature of the skin (detection object) 20 to the temperature-sensitive material over a specified period of time; and a uniform heat-conductive material 130 that contacts the skin 20 and transfers the temperature of the skin 20 to the heat-conductive material in a substantially uniform manner.

[0095] The temperature-sensitive material 110 undergoes visually recognizable changes above a predetermined temperature. As the structure of the temperature-sensitive material, powders, liquids, sheets, etc. whose colors change reversibly (or irreversibly) according to temperature changes can be applied. For example, it can be composed of thermochromic ink, synthetic resins containing thermochromic compositions, etc., but is not limited to this. For example, a substance composed of a leucochromic pigment, a color-developing substance, and a color-changing temperature regulator can be used. In addition, in the case where the temperature-sensitive material is a powder, a method of mixing with a thermoplastic resin or microencapsulation can also be adopted. In addition, microorganisms that emit bioluminescence can also be used.

[0096] The visually recognizable changes of the temperature-sensitive material 110 include not only changes in the color tone of the temperature-sensitive material, but also changes in brightness or chroma. For example, if the initial color is achromatic, it can also change from black to white in a non-step manner as the temperature rises. If the initial color is high chroma, it can also gradually change from dark to light as the temperature rises. In addition, the temperature-sensitive material can also be partially used so that the pattern can be visually recognized by appearing or disappearing according to the temperature change.

[0097] The heat conductive material 120 functions as a spacer material and has a thickness that allows the temperature of the skin 20 to be transferred to the temperature sensitive material 110 over a predetermined time. The thickness of the heat conductive material (the size in the Z-axis direction in the figure) is appropriately selected depending on what material is used for the heat conductive material and how long the predetermined time (time difference) is set.

[0098] The thermally conductive material of this embodiment can be either metal or non-metal, and can be selected from a variety of materials. For example, a gas layer, a vacuum layer, a foamed resin, a resin, wood, cork, etc. can be used, but it is not limited to this. If the thermal conductivity is too high, the above-mentioned time difference cannot be effectively generated. In other words, the thermally conductive material preferably has a certain degree of thermal resistance. The appropriate thermal conductivity of the thermally conductive material is preferably greater than 0.01 (W / m·K) and less than 1 (W / m·K), but it is not limited to this.

[0099] More specifically, the thermal conductive material 120 of the present embodiment may also be made of a thermoplastic resin. The thermoplastic resin may be appropriately selected from polyethylene resin, polyester resin, polypropylene resin, polystyrene resin, acrylic resin, styrene butadiene resin, styrene butadiene acrylonitrile resin, acrylic styrene resin, ethylene acrylic resin, styrene isoprene resin, polyurethane resin, polyester resin, polycarbonate resin, nylon resin, ethylene vinyl acetate resin, polyacetal resin, and vinyl chloride resin, but is not limited thereto.

[0100] In addition, from the viewpoint of processability and thermal conductivity, the thermally conductive material is preferably an engineering resin.

[0101] The uniform thermally conductive material 130 is disposed at a position in contact with the skin 20. The uniform thermally conductive material 130 is used to conduct the temperature of the skin 20 to the thermally conductive material 120 in a substantially uniform manner. The uniform thermally conductive material of the present embodiment may be either metal or non-metal, and may be selected from a variety of materials. However, if the thermal conductivity is too low, the heat conduction to the thermally conductive material will be uneven, which is not preferred. In other words, the uniform thermally conductive material preferably has a thermal conductivity above a certain level. The appropriate thermal conductivity of the thermally conductive material is preferably a thermal conductivity at 25°C (W / m·°C) of 70 or more, but is not limited thereto.

[0102] The uniform heat conductive material of the present embodiment can be appropriately selected from stainless steel, aluminum, platinum, iron, nickel, brass-gold, copper, silver, or alloys thereof, but is not limited thereto.

[0103] In addition, from the viewpoints of cost, processability, and corrosion resistance, the uniform heat conductive material is particularly preferably aluminum (foil).

[0104] The heat insulating part 300 is provided for heat insulation so that heat other than the temperature of the skin 20 is not transferred to the temperature sensing material 110, the heat conducting material 120, and the uniform heat conducting material 130. As shown in the figure, the heat insulating part 300 is provided in a manner covering the temperature sensing material 110, the heat conducting material 120, and the uniform heat conducting material 130. Thus, the sensor part 100 can accurately detect only the body temperature.

[0105] The heat insulating part 300 of this embodiment may also be made of thermoplastic resin. In addition, it may be a gas layer, vacuum, carbon dioxide, air, helium, argon, or other materials. The thermoplastic resin may be appropriately selected from polyethylene resin, polyester resin, polypropylene resin, polystyrene resin, acrylic resin, styrene butadiene resin, styrene butadiene acrylonitrile resin, acrylic styrene resin, ethylene acrylic resin, styrene isoprene resin, polyurethane resin, polyester resin, polycarbonate resin, nylon resin, ethylene vinyl acetate resin, polyacetal resin, and vinyl chloride resin, but is not limited thereto.

[0106] In addition, from the viewpoint of heat insulation performance, vacuum is particularly preferred. In addition, it can also be integrally formed with the fixing part 400 described later (that is, the fixing part 400 also serves as the heat insulation part 300). In this case, the material of the heat insulation part 300 can also be the same material as the fixing part 400.

[0107] The fixing part 400 fixes the sensor part 100 and the heat insulating part 300 at a predetermined position of the user's wrist. Thus, the uniform heat conducting part 130 can be kept in contact with the user's skin 20. In addition, as described above, a part of the fixing part may be used as the heat insulating part 300.

[0108] The fixing part 400 of this embodiment may also be made of thermoplastic resin. The thermoplastic resin may be appropriately selected from rubber resin, silicone resin, and nylon resin, but is not limited thereto.

[0109] According to the above structure, the temperature T of the skin surface is as follows: Figure 2 As shown by the arrows in FIG. 1 , the temperature T is transferred through the uniform heat conductive material 130 and the heat conductive material 120 and reaches the temperature sensitive material 110. Then, the temperature T takes a certain time to advance in the heat conductive material 120 and is transferred to the temperature sensitive material 110. Therefore, according to the embodiment of the present invention, it is possible to detect that the skin temperature has been at a certain temperature for a certain period of time.

[0110] (Second Embodiment)

[0111] Reference Figures 3 to 7 A second embodiment of the present invention will be described. A sensor unit 100 of a heat stroke detector according to this embodiment includes a temperature sensitive material 110 and a heat conductive material 120 .

[0112] like Figure 3 As shown, the sensor portion 100 is directly attached to the skin 20 . Figure 3 The heat stroke detector shown includes one sensor unit 100 .

[0113] like Figure 4 As shown in FIG. 1 , the heat stroke detector may also include a plurality of sensor units. That is, the heat stroke detector may also include a sensor unit 100 and a sub-sensor unit 200. The sensor unit 100 may be applied to Figure 3 The sub-sensor unit 200 of the present embodiment includes a temperature-sensitive material 210 and a heat-conductive material 220. The heat-conductive material 220 is the same material as the heat-conductive material 120, but its thickness is different. That is, the heat from the skin 20 is transferred to the temperature-sensitive material 210 before it is transferred to the temperature-sensitive material 110. According to the heat stroke detector of the present embodiment, the sub-sensor unit 200 can detect before the sensor unit 100 detects, so the sub-sensor unit 200 can realize a function as a prior warning. By confirming the change in the color of the sub-sensor unit 200, etc., the user can know in advance that he is gradually getting heatstroke, so he can move more safely. In addition, the thickness and material of the heat-conductive material 220 can be changed according to when the prior warning is given.

[0114] In addition, if Figure 5 As shown, if the thermal conductivity of the thermal conductive material 220 is different from that of the thermal conductive material 120, it can also be the same thickness as that of the thermal conductive material 120. That is, as long as the above-mentioned function as a prior warning can be achieved by setting the thermal conductivity to be different. For the same reason, the thermal conductive material 220 can also be different from the thermal conductive material 120 in terms of thermal conductivity and thickness.

[0115] Figure 6 The heat stroke detector shown also includes a plurality of sensor units. However, the structure of the sub-sensor unit 200 is different. The sub-sensor unit 100 only includes a temperature-sensitive material 210. According to this structure, heat stroke can be warned in advance more quickly simply by reducing the number of components.

[0116] Figure 7 The heat stroke detector shown in the figure has two sets of sensor units 100 and sub-sensor units 200. The structure of the sensor units 100 and 100a and the structure of the sub-sensor units 210 and 210a are similar to Figure 5 The structure shown is the same, but the response temperature of the temperature sensitive material 110a and the temperature sensitive material 210a is different from that of the temperature sensitive material 110 and the temperature sensitive material 210. In this way, by providing a plurality of sensor units and sub-sensor unit groups, the sensor unit group that responds first can be used as an advance warning function.

[0117] (Third Embodiment)

[0118] Reference Figures 8 to 11 A third embodiment of the present invention will be described. The sensor unit 100 of the heat stroke detector of this embodiment includes a temperature sensitive material 110 , a heat conductive material 120 , and a uniform heat conductive material 130 .

[0119] like Figure 8 As shown, the sensor part 100 is directly attached to the skin 20. The uniform thermal conductive material 130 is in contact with the skin 20. Figure 8 The heat stroke detector shown is composed of one sensor unit 100 .

[0120] like Fig. 9 As shown in FIG. 1 , the heat stroke detector may also include a plurality of sensor units. That is, the heat stroke detector may also include a sensor unit 100 and a sub-sensor unit 200. The sensor unit 100 may be applied to Figure 8 The sub-sensor unit 200 of the present embodiment is provided with a temperature-sensitive material 210, a heat-conducting material 220 and a uniform heat-conducting material 230. The heat-conducting material 220 is the same material as the heat-conducting material 120, but its thickness is different. In addition, similarly to the above-mentioned subject matter, if the heat-conducting material 220 has a different thermal conductivity from the heat-conducting material 120, it can also be the same thickness as the heat-conducting material 120, or it can be a different thermal conductivity from the heat-conducting material 120 and a different thickness. That is, the heat from the skin 20 is transferred to the temperature-sensitive material 210 before being transferred to the temperature-sensitive material 110. According to the heat stroke detector of the present embodiment, the sub-sensor unit 200 can detect before the sensor unit 100 detects, so the sub-sensor unit 200 can realize the function of serving as a prior warning. By confirming the change of the color of the sub-sensor unit 200, the user can know in advance that he is gradually getting heat stroke, so he can move more safely. In addition, the thickness and material of the heat-conducting material 220 can be changed according to when the prior warning is made.

[0121] Fig.10 The heat stroke detector shown also includes a plurality of sensor units. However, the structure of the sub-sensor unit 200 is different. The sub-sensor unit 100 only includes a temperature-sensitive material 210. According to this structure, heat stroke can be warned in advance more quickly simply by reducing the number of components.

[0122] Fig.11 The heat stroke detector shown in the figure has two sets of sensor units 100 and sub-sensor units 210. The structure of the sensor units 100 and 100a and the structure of the sub-sensor units 210 and 210a are similar to Fig. 9 The structure shown is the same, but the response temperature of the temperature sensitive material 110a and the temperature sensitive material 210a is different from that of the temperature sensitive material 110 and the temperature sensitive material 210. In this way, by providing a plurality of sensor units and sub-sensor unit groups, the sensor unit group that responds first can be used as an advance warning function.

[0123] (Fourth Embodiment)

[0124] Reference Figures 12 to 15 A fourth embodiment of the present invention will be described. The sensor unit 100 of the heat stroke detector of this embodiment includes a temperature sensitive material 110 , a heat conductive material 120 , and a heat insulating unit 300 .

[0125] like Fig.12 As shown, the sensor unit 100 is directly attached to the skin 20. The thermal conductive material 120 is in contact with the skin 20. The heat stroke detector includes one sensor unit 100.

[0126] like Fig.13 As shown in FIG. 1 , the heat stroke detector may also include a plurality of sensor units. That is, the heat stroke detector may also include a sensor unit 100 and a sub-sensor unit 200. The sensor unit 100 may be applied to Fig.12 The sub-sensor unit 200 of the present embodiment is provided with a temperature-sensitive material 210, a heat-conducting material 220 and a heat-insulating unit 300. The heat-conducting material 220 is the same material as the heat-conducting material 120, but its thickness is different. In addition, similarly to the above-mentioned subject matter, if the heat-conducting material 220 has a different thermal conductivity from the heat-conducting material 120, it can also be the same thickness as the heat-conducting material 120, or it can be a different thermal conductivity from the heat-conducting material 120 and a different thickness. That is, the heat from the skin 20 is transferred to the temperature-sensitive material 210 before being transferred to the temperature-sensitive material 110. According to the heat stroke detector of the present embodiment, the sub-sensor unit 200 can detect before the sensor unit 100 detects, so the sub-sensor unit 200 can realize the function of serving as a prior warning. By confirming the change of the color of the sub-sensor unit 200, the user can know in advance that he is gradually getting heat stroke, so he can move more safely. In addition, the thickness and material of the heat-conducting material 220 can be changed according to when the prior warning is made.

[0127] Fig.14 The heat stroke detector shown also includes a plurality of sensor units. However, the structure of the sub-sensor unit 200 is different. The sub-sensor unit 100 only includes a temperature-sensitive material 210 and a heat insulator 300. According to this structure, heat stroke can be warned in advance more quickly simply by reducing the number of components.

[0128] Fig.15 The heat stroke detector shown in the figure has two sets of sensor units 100 and sub-sensor units 200. The structure of the sensor units 100 and 100a and the structure of the sub-sensor units 210 and 210a are similar to Fig.14The structure shown is the same, but the response temperature of the temperature sensitive material 110a and the temperature sensitive material 210a is different from that of the temperature sensitive material 110 and the temperature sensitive material 210. In this way, by providing a plurality of sensor units and sub-sensor unit groups, the sensor unit group that responds first can be used as an advance warning function.

[0129] (Fifth Embodiment)

[0130] Reference Figures 16 to 19 A fifth embodiment of the present invention will be described. The sensor unit 100 of the heat stroke detector of this embodiment includes a temperature sensitive material 110 , a heat conductive material 120 , and a fixing unit 400 .

That is, the heat stroke detector may also include a sensor unit 100 and a sub-sensor unit 200. These sensor units are formed so as to be included in the fixing unit 400. The sensor unit 100 can be applied to Fig.16 The sub-sensor unit 200 of the present embodiment is provided with a temperature-sensitive material 210 and a heat-conducting material 220. The heat-conducting material 220 is the same material as the heat-conducting material 120, but its thickness is different. In addition, similarly to the above-mentioned subject matter, if the heat-conducting material 220 has a different thermal conductivity from the heat-conducting material 120, it can also be the same thickness as the heat-conducting material 120, or it can be a different thermal conductivity from the heat-conducting material 120 and a different thickness. That is, the heat from the skin 20 is transferred to the temperature-sensitive material 210 before being transferred to the temperature-sensitive material 110. According to the heat stroke detector of the present embodiment, the sub-sensor unit 200 can detect before the sensor unit 100 detects, so the sub-sensor unit 200 can realize the function of serving as a prior warning. By confirming the change of the color of the sub-sensor unit 200, the user can know in advance that he is gradually getting heat stroke, so he can move more safely. In addition, the thickness and material of the heat-conducting material 220 can be changed according to when the prior warning is made.

[0133] Fig.18 The heat stroke detector shown also includes a plurality of sensor units. However, the structure of the sub-sensor unit 200 is different. The sub-sensor unit 100 only includes a temperature-sensitive material 210. According to this structure, heat stroke can be warned in advance more quickly simply by reducing the number of components.

[0134] Fig.19The heat stroke detector shown in the figure has two sets of sensor units 100 and sub-sensor units 200. The structure of the sensor units 100 and 100a and the structure of the sub-sensor units 210 and 210a are similar to Fig.17 The structure shown is the same, but the response temperature of the temperature sensitive material 110a and the temperature sensitive material 210a is different from that of the temperature sensitive material 110 and the temperature sensitive material 210. In this way, by providing a plurality of sensor units and sub-sensor unit groups, the sensor unit group that responds first can be used as an advance warning function.

[0135] like Fig. 20 As shown in FIG. 1 , both the sensor unit 100 and the sub-sensor unit 200 are provided on the fixing unit 400 and can be visually recognized. Fig.21 As shown, a set of three (or more) sensor units 100, 100a, 100b and sub-sensor units 200a, 200b, 200c may be provided.

[0136] The heat stroke detector of the embodiment described above applies the temperature continuous detector of the present invention to the human body, but the industrial application of the present invention is not limited to this. Fig. 22 As shown in FIG. 1 , the sensor unit 100 may be attached to a device that is intended to detect a situation where the device has been operating at a certain temperature for a certain period of time (thermal runaway, etc.). Fig.23 As shown, it can also be used to confirm whether plants, etc. are above a specified temperature. In this case, it can also be directly set in a flowerpot, soil, etc.

[0137] In addition, if Fig.24 As shown, it can also be applied to the human body. For example, the temperature continuity detector 10 can be installed not only on the wrist, but also on the surface of the ankle, waist, neck, etc. to detect heat stroke.

[0138] In the above-mentioned embodiments of the present invention, as the structure of the sensor part (and the sub-sensor part), a combination of a temperature-sensitive material, a heat-conductive material, a uniform heat-conductive material, a heat-insulating part, and a part of the fixing part is described, but the present invention is not limited to this. For example, with respect to the sensor part, it can be only a temperature-sensitive material and a heat-conductive material (structure 1-1), or it can be a temperature-sensitive material, a heat-conductive material, and a uniform heat-conductive material (structure 1-2). In addition, with respect to the sub-sensor part, it can be only a temperature-sensitive material (structure 2-1), or it can be a temperature-sensitive material and a heat-conductive material (structure 2-2), or it can be a temperature-sensitive material, a heat-conductive material, and a uniform heat-conductive material (structure 2-3). With respect to the sensor part, it can be only a sensor part, or it can be a combination of a sensor part and a sub-sensor part (a combination of their number). In addition, a heat-insulating part, a fixing part, or both can be combined.

[0139] The above embodiments are merely illustrative for easy understanding of the present invention and are not intended to limit the present invention. The present invention can be modified and improved within the scope of the present invention, and the present invention naturally includes equivalent forms.
