FIGS. A sweating amount measurement patch 10 is shown. The sweating amount measurement patch 10 is provided with a first film 12 coated with a pressure-sensitive adhesive 11 that forms an adhesive portion on one side of a transparent film, and the material thereof is made of a flexible and transparent synthetic resin. For example, polyolefin such as polyester is used. The first film 12 is cut into, for example, an oval shape that is long in one direction, and both end portions 12b and 12c in the longitudinal direction are provided in a semicircular shape.

  The surface 12a of the first film 12 is subjected to predetermined printing. By this printing, a long and thin rectangular display unit 14 along a center line parallel to the longitudinal direction of the first film 12 is provided in a colorless and transparent manner. One end 14a in the longitudinal direction of the display unit 14 is located slightly closer to the one end 12b than the longitudinal center of the first film 12, and the other end 14b of the display unit 14 is the first film. 12 near the end 12c. An opaque non-display portion 16 is formed around the display portion 14 by printing. The non-display portion 16 is provided with scales 18 at predetermined intervals along one side edge portion parallel to the longitudinal direction of the display portion 14. Here, the scale 18 is provided with “25”, “50”, “75”, and “100” at equal intervals toward the end 14 b, with the end 14 a of the display unit 14 being “0”. On the side of the non-display portion 16 opposite to the scale 18 with the display portion 14 in between, a unit of site sweating amount is printed. This is a unit indicating the amount of perspiration per skin area facing an opening 26 on the back side described later. A character such as “hydration” may be provided in the middle of the scale 18.

  A sweat adsorbent 20 having a larger area than the display unit 14 is provided on the back surface 12 d of the first film 12 so as to face the display unit 14. The sweat adsorbent 20 is made of a fibrous material that is highly hygroscopic and absorbs sweat and easily penetrates, and is, for example, a filter paper or a hydrophilic nonwoven fabric. The color former 22 is uniformly attached to the outer surface of the sweat adsorbent 20 via a binder or the like.

Here, the color former 22 is preferably at least one selected from edible pigments, acid dyes, basic dyes, direct dyes, acid mordant dyes, and reactive dyes. For example, commercially available Blue No. 1, Blue No. 4, Blue No. 404, Yellow No. 4, Red No. 102 and the like. Examples of the acid dye include Cyanol Red NBR, Brilliant Scarlet 3B, Acid Fast Orange SG, Amaranth, Acid Rhodamine B, Eosin G, Acid Milling Red RS, Alizarin Direct Blue AGG, Indigo Carmine Blue G, Acid Milling Cyanine 5R. . Examples of the basic dye include cation red 6B, cation pink FG, crystal violet, and methylene blue B. Direct dyes are, for example, Cyanol Light Red F5B, Direct Fast Scarlet 4BS, Benzoparpurin 4B, Direct Fast Orange S, Direct Rojurin Red B, Chlorunch Fast Red 6BLL, Syria Thread 4B, Serious Splash Red Violet RL, Serious Splash Violet BL, direct sky blue 5B.

Examples of reactive dyes include Reacton Red 2B-F, Procion Rubin BS, Cibacron Violet F2R-A, and Procion Brilliant Blue RS. One or more water-soluble dyes are blended in the ink.

  As the binder, for example, dextrin which is a water-soluble fine powder is used. For example, the color former 22 is mixed with dextrin and applied to the sweat adsorbent 20. The color former 22 is colored by dissolving in sweat and is an irreversible color change.

  A second film 24 is provided on the back surface 12 d of the first film 12 so as to cover the sweat adsorbent 20. The second film 24 is attached with the adhesive 11 of the first film 12 such that the adhesive 25 is applied to one side of the transparent film, and the adhesive 25 is stacked on the opposite side of the first film 12. The second film 24 is provided with an opening 26, from which the second film 24 is cut out, facing the end 14 a of the display unit 14. The sweat adsorbent 20 is exposed inside the opening 26. The pressure-sensitive adhesive 25 of the second film 24 is provided with a material that is reliably affixed to the skin and does not easily peel off even when sweating.

  The sweating amount measurement patch 10 is affixed to a release sheet 28 having the same shape as or larger than that of the first film 12. It is attached so as to be peelable by the adhesive force of the adhesive 25 of the sweating amount measurement patch 10. A plurality of identical sweating amount measurement patches 10 may be attached to one large release sheet 28. The sweating amount measurement patch 10 to which the release sheet 28 is attached is packaged and sealed in a bag such as a resin film.

  Next, a method of using the sweating amount measurement patch 10 of this embodiment will be described. First, the release sheet 28 is peeled off from the sweating amount measurement patch 10 to expose the adhesive 25. And the sweating amount measurement patch 10 is affixed on the measurement site | part of a test subject's body. The measurement site is preferably inside the forearm, for example. The amount of sweat at this site indicates an average value of the amount of sweat from each site of the whole body, and the amount of sweat of the whole body can be examined by examining the amount of sweat per unit area. When the sweating amount measurement patch 10 is affixed to the subject and left to stand, sweat secreted from the skin of a certain area facing the opening 26 of the sweating measurement patch 10 enters from the opening 26 and the sweat adsorbent 20. To be absorbed. It permeates into the sweat adsorbent 20 in proportion to the amount of sweat, and permeates widely semi-quantitatively by the chromatographic principle. The color former 22 of the sweat adsorbent 20 dissolves and develops color due to the absorbed sweat. The color of the color former 22 is visually recognized from the display unit 14, and “0” on the scale 18 of the display unit 14 is colored first closest to the opening 26. When the amount of sweat increases and the amount of sweat absorbed by the sweat adsorbent 20 increases, sweat permeates and diffuses along the longitudinal direction of the sweat adsorbent 20 to spread the color. The color of the color former 22 is visually recognized from the display unit 14, and the scale 18 at the end of the developed color is read to confirm the sweating amount at the site.

  According to the sweating amount measurement patch 10 of this embodiment, the sweating amount of the whole body can be measured semi-quantitatively by a simple operation that is simply put on the inside of the subject's forearm and left to stand. The structure of the sweating amount measurement patch 10 is simple and inexpensive, and can be used easily and can be disposable. The sweating measurement patch 10 is about 1 g and is thin and lightweight, so there is no sense of incongruity. Various sports such as soccer, baseball, basketball and golf, and outdoor work during the day such as construction / civil engineering and garden work. The amount of sweating can be measured while doing. Further, since the adhesive 25 of the sweating amount measurement patch 10 is made of a material that does not easily peel off even when sweating, the sweating amount can be used as a weight loss check in a sauna or athletic gym. In terms of medical care, it is possible to easily confirm symptoms of dehydration and anhidrosis, and to obtain treatment guidelines such as measurement of night sweats. Since the display unit 14 is provided with a scale 18, anyone can easily read the site sweating amount, and the whole body sweating amount can be calculated using the site sweating amount.

  Thereby, the amount of water loss of the whole body can be known from the amount of sweating, and it can be used as a measure of replenishment of water and a break as a countermeasure against heat stroke. For example, it is possible to obtain a standard for hydration with a sports drink or the like for every sweat amount of 200 to 300 g of whole body sweat amount. If it is a heat stroke countermeasure, it is preferable to replenish the lost water amount for every 150 to 200 g of perspiration. To measure the amount of sweat accurately, it is time-consuming to measure the weight by removing the clothing before and after exercise and adjusting the amount of ingested water and discharged urine from the difference in weight, but measuring the amount of sweat According to the patch 10, the measurement can be easily performed. The color former 22 of the sweating amount measurement patch 10 has an irreversible color change, and the sweating amount can be recorded as it is.

  Children with short stature are close to the ground, so the temperature is high and special attention is required. In addition, infants and the elderly are prone to dehydration, it is difficult to maintain moisture in the body, and fine hydration is required during activities. Therefore, by using this sweating amount measurement patch, water is appropriately replenished according to the sweating amount in sports or the like, which leads to prevention of heat stroke and reduction of fatigue after exercise. For example, in volleyball, the ball touches the forearm, so measurement with the upper arm is preferable, and the pasting location may be changed as appropriate.

  In the sweating amount measurement patch 10 of this embodiment, the scale 18 may be other than the above, and as shown in FIG. 3, “0” to “1000” are provided at 200 intervals, and the unit is the whole body sweating amount (g / 60 kg). ). The whole body sweat amount is a conversion of the site sweat amount, and the whole body sweat amount can be measured immediately in an intense sport of 1 to 2 hours. The maximum amount of sweat from the entire body is 700 to 900 g, and it is possible to know how much sweat was applied to the entire body.

  In addition, the sweating amount measurement patch 10 of this embodiment can design the shape of the display part 14 freely. For example, as shown in FIG. 4, a circular display unit 30 is provided in a colorless and transparent manner on a center line parallel to the longitudinal direction of the first film 12. A plurality of display units 30 having the same shape are provided at equal intervals along the center line of the first film 12, and seven display units 30 are provided here. A non-opaque non-display portion 16 is formed around the display portion 30 by printing. On the back surface 12 d of the first film 12, a single sweat adsorbent 20 that is long in one direction is provided facing the seven display units 30, and a second film 24 is provided to cover the sweat adsorbent 20. ing. The second film 24 is provided with an opening 26 from which the second film 24 is cut out at a portion facing the display unit 30 closest to the end 12 b of the first film 12. The sweating amount measurement patch 10 can also measure the sweating amount easily and easily. Since the display part 30 is the same circular shape and is provided independently, the color of the color former 22 is easily visible. In addition, the shape of the display unit 30 may be a square or some mark other than a circle, and any number may be provided, and scales or characters may be printed around the display unit 30.

  In addition to the above, the color former of the present invention may be a water-soluble dye such as a water-based ink. In this case, the color former may be printed on a backing paper such as a filter paper as a sweat adsorbent with an inkjet printer or the like, and is easy to manufacture. .

  Furthermore, the color former is not particularly limited as long as it absorbs sweat and develops a visible color, and it may be visible by changing the light transmissivity and refractive index without changing itself. For example, the color former of the display portion is a sweating layer in which a high refractive index colored layer different from this hue is provided on the ground color of the colored layer so that the ground color can be observed by increasing the light transmission by permeation of sweat. A quantity measuring patch may be used. The display unit is provided with a layer containing a white pigment such as white carbon on a bright ground color such as red or blue, and the white color changes to a bright ground color such as red or blue by permeation of sweat. It is.

  Moreover, the following are preferable as the color former for the sweat amount measurement patch suitable for measuring a minute amount of sweat. For example, a sweat absorbent material impregnated with a pH indicator that changes color with sweat may be used. As the pH indicator, methyl red, bromothymol blue thymol blue and the like are preferable. The color changes from acidic to neutral due to permeation of sweat. In addition, the color former may be cobalt chloride, and the sweat absorbent may be cobalt chloride impregnated filter paper. In this case, the evaporated sweat can be accurately detected and displayed.

The sweating amount measuring patch having these structures is suitable for measuring a minute amount of sweating of 10 mg / cm ² or less because it reacts with a small amount of sweat and has a fast discoloration rate.

In addition, a sweating amount measurement patch provided with both a water-soluble color former and a chemical color former may be used. A chemical color former such as cobalt chloride reacts with a small amount of sweat, so it is preferable for a small amount of sweat, but not suitable for a large amount of sweat. On the other hand, the water-soluble color former is suitable for a large amount of perspiration, but a small amount of perspiration of 10 mg / cm ² or less tends to develop color slowly. Therefore, by combining both color formers, a sweating amount measuring patch suitable for measuring a trace amount to a large amount of sweat can be obtained.

  In this case, the plurality of openings and the sweat adsorbent may be independently attached to the second film, and the amount of sweat adsorbed on each sweat adsorbent may be different, and the color former provided on the sweat adsorbent is as described above. Different types or amounts may be used. Accordingly, the amount of sweating can be measured regardless of whether the amount of sweat is large or small, and it is possible to cope with a large amount of sweating with high sensitivity.

  In addition, the sweat amount measurement patch of the present invention may be a wristwatch shape or a wristband shape in addition to the adhesive bandage shape made of a transparent film, and it is difficult to peel off even by intense movement by making a wristwatch shape or a wristband shape. Installed securely. The color former is provided only on the part facing the opening, in addition to the one provided on the sweat adsorbent, so that the sweat adsorbent diffuses as the amount of sweat adsorbed increases. It may be measured. Furthermore, the sweating amount measurement patch is not limited to the above structure, and may be one in which a pressure-sensitive adhesive is uniformly attached to the back surface in a state where a sweat adsorbent is superimposed on a transparent film.

  The color former may be provided on the first film side surface of the sweat adsorbent. In this case, it is preferable to provide a colorless and opaque thin cover that absorbs water so that the color of the sweat adsorbent cannot be seen from the display portion.

Moreover, the sensitivity of the sweating amount measurement patch can be variously adjusted by combining the area of the opening for absorbing sweat and the sweat absorption capacity of the sweat adsorbent. That is, by measuring the amount of perspiration per minute of 0 to 10 mg / cm ² by measuring the opening for sweat absorption, for example, 10 mm × 10 mm, and the sweat absorbing capacity of the sweat adsorbent is 100 mg or less. A patch for measuring the amount of sweating can be obtained. Further, by setting the opening for absorbing sweat to 8 mm × 6 mm and the sweat absorbing capacity of the sweat adsorbent to 500 mg, the perspiration amount per hour can be measured in a large amount of 10 to 150 mg / cm ^2. A quantitative patch is obtained.

The perspiration amount was measured by the perspiration amount measurement patch of the present invention, and compared with the perspiration amount by a perspiration meter (integrator). The test subject was a woman (28 years old, height 164 cm, weight 48 kg). A sweat measurement patch was applied to the upper arm of the test subject. After about 30 minutes, the scale of the sweat test patch showed 20 mg / cm ² . The perspiration meter (accumulator) measured at the same time was 18.5 mg / cm ² , and the perspiration amount measurement patch showed a value close to that of the perspiration meter.

  The amount of sweating was measured with the patch for measuring the amount of sweating of this invention and compared with the amount of sweating of the whole body calculated from the change in body weight. The test subject was a male (age 32, height 176 cm, weight 71 kg), affixed to the inner side of the test subject's forearm, and ran for about 30 minutes on the road at an external temperature of 30 ° C. During this period, the perspiration amount indicated by the perspiration amount measurement patch was converted to a weight of 71 kg and indicated 200 scales. On the other hand, the weight loss during this period was 260 g.

  It is difficult to accurately calculate the whole-body sweat amount of the whole body from the sweat amount of a part of the body, depending on the surface property of the skin, the body weight, and other factors. Therefore, in order to more accurately measure the amount of sweating, the relationship between the site sweating amount at the site where the sweat test patch was applied and the whole body sweating amount was examined.

First, the coefficient k = B / A is obtained. Here, A is a scale of the whole body sweat amount of the sweat amount measurement patch, and B is a weight loss amount (g). Here, a method for measuring B will be described. First, measure the weight without wearing clothes, then apply a sweating measurement patch to a part of the body, for example, inside the upper arm, perform sports for a certain period of time, then measure the weight without wearing clothes again . As a result, the weight before the sport was 65.55 kg, the weight after the sport was 65.10 kg, and the whole body sweat amount shown by the sweat amount measurement patch was 400. This
k = (65550−65100) /400=1.125
It becomes.

By using this calculated k, it is possible to measure the whole body sweating amount only by applying the sweating amount measuring patch. For example, when the scale of the sweating amount measurement patch is 350, the sweating amount of the whole body is as follows.
Sweating amount = 350 × 1.125 = 394
Therefore, the sweating amount of the whole body is 394 g as a result of correction. If not corrected, it is determined to be 350 g.

A sweating measurement patch was applied to the inner side of the forearm of a man (34 years old, weight 63.0 kg, height 180 cm) to measure the amount of sweating, and compared with the amount of whole body sweating calculated from the change in body weight. The measurement was performed by running on a road with an outside temperature of 31 ° C. for 30 minutes by bicycle. The amount of sweat on the inner side of the forearm during this period is 39.7 ± 2.6 mg / cm ² in terms of the amount of sweat per unit area on the inner side of the forearm (cumulative amount). Indicates a 340 scale. On the other hand, the weight loss during this period was 350 g.
Therefore, the coefficient k is as follows.
k = 350/340 = 1.029

  The amount of sweating was measured with a sweating amount measurement patch and compared with the amount of whole body sweating calculated from the change in body weight. The test subject was a male (54 years old, height 165 cm, weight 66 kg), affixed to the inner side of the subject's forearm, and played golf at an outside air temperature of 30 to 34 ° C. for about 4 hours. Meanwhile, 500 g of soft drink was ingested. The perspiration amount indicated by the perspiration amount measurement patch was 530 in terms of 66 kg body weight. On the other hand, the weight loss during this period was 550 g after correcting the weight of the drinking water, and it was found that the sweat amount measurement patch showed a value close to the sweat amount calculated from the weight loss.
