[Embodiment 1]
Hereinafter, one embodiment of the present disclosure will be described in detail.

<Structure of fittings>
2001 and 2002 of FIG. 2 are plan views showing an example of the fitting 2 when the fitting 2 is viewed from the inside. 2003 of FIG. 2 is a cross-sectional view taken along the line AA in 2002 of FIG. 2002 of FIG. 2 shows a state in which the portion of the fitting 2 provided with the storage portion 21 is folded back. The inside (back side) of the fitting 2 is the side that comes into contact with the dog when the fitting 2 is attached to the dog, and the outside (front side) of the fitting 2 is the side that does not come into contact with the dog. ..

As shown in 2001 to 2003 of FIG. 2, the attachment 2 is attached to a dog, and includes an electrode structure 1, a lead wire 3, a storage portion 21, and a button 22.

The fitting 2 is, for example, a band-shaped member that can be wrapped around the body of a dog. The material of the fitting 2 is, for example, a washable material (eg, cloth). In this case, the dog's sebum, body hair, etc. adhering to the attachment 2 can be easily washed away. If this point is not taken into consideration, various materials can be used as the material of the fitting 2, including a non-washable material.

With the fitting 2 wrapped around the dog, the first end portion provided with the storage portion 21 and the second end portion not provided with the storage portion 21 are removably connected. For example, a hook-and-loop fastener is provided on the inner portion of the first end portion and the outer portion of the second end portion. By connecting the first end and the second end on the back of the dog, the measuring device 4 is arranged on the back of the dog, and the electrode structure 1 is brought into contact with the chest side of the dog. As described above, the fitting 2 can be attached to the dog. That is, the electrode structure 1 is arranged at a position where the electrode 11 of the fitting 2 comes into contact with the chest side of the dog when the fitting 2 is attached to the dog.

A material having flexibility (stretchability) is used for at least a part of the fitting 2. In this case, since the fitting 2 can be fitted regardless of the body shape (posture) of the dog, the electrode structure 1 can be pressed against the chest side of the dog with an appropriate force to be brought into close contact with the dog. When the pressing force is too strong, the force can be reduced by extending the surface of the mounting tool 2 that covers the electrode structure 1.

By using a flexible material for the fitting 2 and providing hook-and-loop fasteners at the first end and the second end, the first end and the second end (that is, the back of the dog). The tightening force of the fitting 2 on the dog can be adjusted. The hook-and-loop fastener is installed in the girth direction of the dog with a length of a predetermined length or more, for example, 1 cm or more. The length around the waist of the fitting 2 can be adjusted and the tightening force can be changed depending on the fastening position where the hook-and-loop fastener is fastened. The first end and the second end may be provided with a member capable of adjusting the tightening force, and examples of the member include a buckle, a belt, a button, a string, or a band in addition to the hook-and-loop fastener. ..

Note that the fitting 2 does not necessarily have to be a band-shaped member, and may be wear that can be worn through the forefoot, for example. Further, the storage portion 21 is provided at the first end portion, but the present invention is not limited to this, and one electrode structure 1 may be provided at the first end portion and the other electrode structure 1 may be provided at the second end portion. Absent. In this case, the first and second ends are connected near the chest side of the dog. When the fitting 2 is attached to the dog, if the electrode structure 1 is arranged on the fitting 2 so as to abut on the chest side of the dog, the electrode structure 1 and the storage are stored at any position of the fitting 2. The section 21 may be provided.

In addition, as the attachment 2, there are a plurality of types of attachments having different sizes (lengths) so as to be able to cope with various dog types or physical disparities in order to ensure close contact with the dog when attached. It may be prepared. In this case, it is not always necessary to use a flexible material for the fitting 2.

As described above, the electrode structure 1 is provided on the fitting 2 so as to abut on the chest side of the dog. The electrode structure 1 includes an electrode 11 that is electrically connected to the measuring device 4 and is brought into contact with the dog's body surface (measurement site on the chest side). The measurement site is the surface of the body (hair-cutting portion) where the hair is shaved on the chest side, and is the portion where the electrode 11 is in contact. By setting the hair-cutting portion as the measurement portion in this way, the accuracy with which the electrode 11 contacts the measurement portion can be improved, and the contact resistance between the electrode 11 and the measurement portion can be reduced. The specific structure of the electrode structure 1 will be described later.

The electrode 11 is for detecting a signal indicating a dog's electrocardiogram as biological information. However, the electrode 11 may detect biological information other than the electrocardiogram of the dog. The area of the electrode 11 may be any size that can be detected accurately biometric information is for example 0.25 cm ² or more and 900 cm ² or less. Further, as shown in 1001 of FIG. 1, the electrode 11 has a rectangular shape when viewed from the outer surface 11a (see 1002 of FIG. 1) side (when viewed in a plan view). However, the shape of the electrode 11 when viewed in a plan view may be any shape such as a circle. Further, the two electrodes 11 are provided on the fitting 2 so that the adjacent sides are substantially parallel to each other (in the same direction), but the adjacent sides are provided so as to be in different directions from each other. You may.

The electrode 11 has a structure (eg, a porous structure having minute holes) inside, which allows water supplied from the water supply material 122 (see FIG. 1) to pass through. That is, a hole for passing the above-mentioned moisture is formed inside the electrode 11. As a result, the water retained by the water supply material 122 can be supplied to the measurement site through the electrode 11. As will be described later, by supplying water to the electrode 11 or the measurement site, the contact resistance between the electrode 11 and the measurement site can be reduced, so that the measurement accuracy can be improved. As the water content, a liquid having a certain amount or more of electrolyte, such as tap water and salt water, is used. As the water content, it is desirable to use a liquid having a conductivity of 100 μS / cm or more. Examples of the material of the electrode 11 having the above structure include a conductive cloth. If the electrode 11 has the above structure, the material of the electrode 11 is not limited to the conductive cloth, but is a conductive material such as a metal, a conductive polymer, or a conductive carbon. It may be. The timing for supplying water to the water supply material 122 may be appropriately set by the user who uses the measuring device 4. The water supply material 122 may be dry during the time when the measuring device 4 is not used for the measurement.

When, for example, a conductive cloth is used as the material of the electrode 11, the electrode 11 has flexibility. In this case, when the fitting 2 is attached to the dog, even if the fitting 2 is curved according to the body shape of the dog, the shape of the electrode 11 can be changed according to the curvature. Therefore, it is possible to reduce the possibility that the measurement site is damaged by the electrode 11 coming into contact with the measurement site.

As described above, in order to reduce the contact resistance between the electrode 11 and the measurement site, the hair at the measurement site and its surroundings is shaved. At this time, using a shaving fitting that has substantially the same shape as the fitting 2 and has an opening formed at a position corresponding to the position where the electrode 11 is arranged in the fitting 2, the measurement site and the measuring portion The hair around it may be shaved. By using the shaving tool, it is possible to accurately and easily shave the measurement site to which the electrode 11 abuts and the body hair around the measurement site. Further, when a plurality of types of fittings 2 having different sizes depending on the type of dog and the like are prepared, a shaving fitting may be prepared for each size of the fitting 2. In this case, it is possible to shave the body hair accurately and easily according to the plurality of types of wearing tools 2.

The lead wire 3 is a signal line that electrically connects the measuring device 4 connected to the button 22 and the two electrodes 11. Specifically, one end of the lead wire 3 is electrically connected to the electrode 11, and the other end is electrically connected to the button 22. As a result, the lead wire 3 outputs a signal indicating the electrocardiogram of the dog detected by the two electrodes 11 to the measuring device 4.

The measuring device 4 is an electronic device that measures the electrocardiogram of a dog. The measuring device 4 is housed in the storage unit 21 and is electrically connected to a button 22 (a button having conductivity) provided in the storage unit 21. A lead wire 3 connected to each of the two electrodes 11 is connected to each of the two buttons 22. Therefore, by electrically connecting the measuring device 4 to the button 22, it is possible to process a signal indicating the dog's electrocardiogram obtained from the dog. The measuring device 4 may be a device that transmits the processed signal to an external analysis device, or may be a device that also has a function of analyzing the signal. The measuring device 4 measures the electrocardiogram of the dog by detecting the potential difference between the respective electrodes 11.

The measuring device 4 includes, for example, a battery, an electrocardiographic signal processing circuit, and a microcomputer for performing the above-mentioned signal processing and / or analysis. The electrocardiographic signal processing circuit and the microcomputer are mounted on a substrate that can be electrically connected to the button 22, for example. The measuring device 4 may also have an acceleration sensor or a temperature / humidity sensor mounted on the substrate. When the measuring device 4 has a function of transmitting the processed signal to an external analyzer, the measuring device 4 includes, for example, a communication module equipped with an antenna (eg, a BLE (Bluetooth (registered trademark) Low Energy) module). Is also good. In this case, the measuring device 4 can transmit the processed signal to an external analysis device by the BLE module.

Further, the biological information to be measured by the measuring device 4 is not limited to the electrocardiogram, and may be any such as heartbeat, body temperature, and blood glucose level. In this case, the measuring device 4 may be provided with a signal processing circuit capable of measuring various biological information.

The storage unit 21 is a bag-shaped member that stores the measuring device 4 inside. In other words, the storage unit 21 forms a space for accommodating the measuring device 4. The storage portion 21 is outside the fitting 2 and is provided at the first end of the fitting 2. The storage portion 21 is arranged on the back side of the dog when the fitting 2 is attached to the dog. By arranging the storage portion 21 on the back side of the dog, it is possible to reduce the possibility that the dog will destroy the storage portion 21 or the stored measuring device 4 by the paws or mouth. Further, when the measuring device 4 is damaged, the possibility that the dog is injured by the broken pieces of the measuring device 4 can be reduced. If this point is not taken into consideration, the storage portion 21 may be provided at any position of the fitting 2 as described above. Further, the storage portion 21 may be provided with a lid portion for preventing the stored measuring device 4 from jumping out.

The button 22 is for electrically connecting the lead wire 3 and the measuring device 4. The button 22 is made of a conductive material. As the material, for example, Ni-plated stainless steel or the like is used. The material of the button 22 may be a material such as a metal, a conductive polymer, or a conductive carbon. Further, the button 22 may be a non-conductive button whose surface is covered with a material such as metal, a conductive polymer, or a conductive carbon. The button 22 is provided on the portion of the mounting tool 2 where the storage portion 21 is provided.

<Structure of electrode structure>
FIG. 1 is a diagram showing a configuration example of the electrode structure 1. 1001 in FIG. 1 is a plan view of the electrode structure 1, and 1002 in FIG. 1 is a cross-sectional view of the electrode structure 1. The electrode structure 1 includes an electrode 11 that comes into contact with a measurement site (body surface on the chest side) and an electrode holding portion 12 that holds the electrode 11. The electrode structure 1 has flexibility as a whole. That is, each member constituting the electrode structure 1 described later has flexibility. As a result, the shape of the electrode structure 1 can be changed according to the curvature of the fitting 2 regardless of the body shape of the dog. Therefore, the electrode 11 can be brought into close contact with the measurement site. The electrode structure 1 may have a shape in which the surface on which the electrode 11 is provided is curved with the electrode 11 as the apex. In this case, the electrode structure 1 can be easily brought into close contact with the measurement site.

As shown in FIG. 1, the electrode 11 is electrically connected to the measuring device 4 by being connected to the conducting wire 3. As shown in 1002 of FIG. 1, the lead wire 3 is connected to the inner surface 11b of the electrode 11 opposite to the outer surface (surface) 11a in contact with the measurement site.

In the present embodiment, as shown in 1001 of FIG. 1, the electrode 11 and the lead wire 3 are fixed so as to be in contact with each other in a surface. Reference numeral Ar in FIG. 1 indicates a contact region between the electrode 11 and the lead wire 3. In the present embodiment, the conducting wire 3 is a cloth having conductivity like the electrode 11, and is made of the same material as the electrode 11 (eg, silver-plated thread). Further, the lead wire 3 has a length (eg, several tens of cm) that allows the button 22 (see FIG. 2) and the electrode 11 to be connected, and has a surface contact with the inner surface 11b of the electrode 11. It is strip-shaped with a width (eg, several cm). After the end of the lead wire 3 is brought into contact with the inner surface 11b of the electrode 11, the electrode 11 and the lead wire 3 are fixed (crimped, closely attached) by sewing with a thread of the same material. As a result, the electrode 11 and the lead wire 3 can be electrically connected in a state where the resistance generated by the contact between the electrode 11 and the lead wire 3 is reduced.

It is not always necessary to connect the electrode 11 and the lead wire 3 using threads of the same material, and the electrodes 11 and the lead wire 3 may be connected using threads of different materials, or may be bonded using an adhesive or the like. Further, the conducting wire 3 does not necessarily have to be a cloth having conductivity of the same material as the electrode 11, and may be a cloth having conductivity of a different material, and is not a cloth having conductivity but a metal wire ( Example: cable), conductive polymer, conductive tape, etc. may be used. Further, the electrode 11 and the lead wire 3 may be a common member (the electrode 11 and the lead wire 3 may be integrally formed).

However, the resistance value due to the contact between the electrode 11 and the lead wire 3 is reduced to such a size that the electrode 11 and the lead wire 3 are electrically connected. Therefore, regardless of the material or shape of the electrode 11 and the lead wire 3 and the material (eg, thread, adhesive) for connecting the electrode 11 and the lead wire 3, the electrode 11 and the lead wire 3 are attached to the fitting 2. It is firmly fixed so that the lead wire 3 does not come off from the electrode 11 by use. Further, the electrode 11 and the lead wire 3 are connected at the connecting portion so as to be equal to or less than the resistance value per unit length of the electrode 11 or less than or equal to the resistance value per unit length of the lead wire 3.

In the present embodiment, the electrode holding portion 12 includes a storage material 121, a water supply material 122, a waterproof material 123, and an elastic material 124. As shown in 1002 of FIG. 1, in the electrode structure 1 of the present embodiment, the electrodes 11, the water supply material 122, the waterproof material 123, and the elastic material 124 are arranged in this order from the side that comes into contact with the measurement site. Forming a structure.

The storage material 121 stores the water supply material 122, the waterproof material 123, and the elastic material 124 inside. The material of the storage material 121 is not particularly limited, but is, for example, cloth. In this case, the electrode 11 can be fixed to the storage material 121 by sewing the periphery of the electrode 11 to the storage material 121 with a thread. In addition, it is easy to secure the air permeability inside the storage material 121. Therefore, for example, after washing the fitting 2, the storage material 121 and the members stored inside the storage material 121 can be efficiently dried. If this point is not taken into consideration, any material may be used for the storage material 121.

Further, a through hole is formed in a part of the storage material 121 (the side portion in the example of FIG. 1). The lead wire 3 connected to the electrode 11 is taken out to the outside of the storage material 121 through the through hole. In addition, outside the storage material 121, a shield material 31 is provided around the lead wires 3 so that the lead wires 3 taken out from each of the two electrodes 11 are not electrically connected to each other. On the other hand, inside the storage material 121, it is not always necessary to provide the shield material 31 around the lead wire 3.

Further, the bottom of the storage material 121 may be detachably connected to the fitting 2. For example, a hook-and-loop fastener is provided at the bottom of the storage material 121 and the portion of the fitting 2 to which the electrode structure 1 is connected. Thereby, the position of the electrode structure 1 in the fitting 2 can be easily changed.

The water supply material 122 supplies water to the electrode 11 or the measurement site. The water supply material 122 can retain water, and when the electrode 11 is in contact with an animal, the water is supplied to the body surface of the animal with which the electrode 11 or the electrode 11 is in contact. .. The water supply material 122 is arranged so as to overlap the electrode 11. The water supply material 122 has a water absorption holding function capable of holding water for a predetermined time, and a water supply function capable of supplying water to the electrode 11 or the measurement site when the attachment 2 is attached to the dog. The predetermined time is, for example, at least one electrocardiographic measurement time (eg, 5 minutes or more and 250 hours or less). The water supply material 122 has, for example, a porous structure or a structure similar to the porous structure, and is formed of a material capable of retaining water absorption within the structure. Examples of the material include a woven fabric having a water-absorbing function, a non-woven fabric or a mixed non-woven fabric, a water-absorbing polymer using a polymer material, cotton or a sponge. The water-absorbing polymer may be a polymer having humidity control property, moisture absorption / release property, and high water absorption property. The polymer includes, for example, at least one selected from the group consisting of polyester fibers, bamboo fibers, acrylic fibers, aclite fibers, cupra fibers, nylon fibers and polyurethane fibers. Further, the water supply material 122 has a size and a thickness sufficient to realize the water supply holding function. The water supply material 122 preferably contains a porous body. The porous body preferably contains voids having a diameter of 0.38 nm or more and 1 mm or less, and has a porosity of 1% or more and 99% or less. The porous body preferably comprises at least one selected from the group consisting of sponge, cotton, woven fabric and non-woven fabric.

(Measuring method of void diameter and porosity)
A 30 mm square square is cut out from the porous body to be measured and used as a sample. The diameter and porosity of the voids are measured by observing the surface of the sample with a scanning electron microscope (SEM) or the like. The observation magnification of the SEM is appropriately adjusted according to the size of the void, and then photographs are taken at three different positions on the sample surface. Binarize the photograph taken and display the holes on the sample surface in black.

For the photograph of the surface of the sample that has been binarized, the analysis software (Image-ProPlus) is used to calculate the equivalent circle diameter for 2000 arbitrarily selected voids, and the average value is taken as the diameter of the voids. To do.

In addition, the area of the void portion is measured using analysis software (Image-ProPlus) for the photograph of the surface of the sample that has been binarized. The area of the voids measured in this way is divided by the area of the sample surface shown in the photograph, and the average of the above three locations is taken as the porosity of the porous body.

In the present embodiment, water is supplied to the water supply material 122 through the electrode 11 or the storage material 121 using a dropper, a spray, or the like. The amount of water retained in the water supply material 122 at one time (the amount of water that can be retained by the water supply material 122) is, for example, several cc (eg: 1 cc or more and 3 cc or less, or 1 cc or more and 10 cc or less). As a result, the water supply material 122 can retain water for the predetermined time.

By providing the water supply material 122, water can be supplied to the electrode 11, so that water can be supplied to the measurement site through the electrode 11. Further, by providing the water supply material 122, it is possible to supply water from the periphery of the electrode 11 to the measurement site. As a result, water can be supplied to the contact portion between the electrode 11 and the measurement site. Therefore, the contact resistance generated in the contact portion can be reduced. Further, since the water supply material 122 can retain water for a predetermined time, for example, by being formed of the above material, the retained water is brought into contact with the water supply material 122 for a predetermined time at least when measuring the electrocardiogram. Can be supplied to parts. Therefore, since the signal from the electrode 11 can be continuously and stably supplied to the measuring device 4, stable (long-term continuous) electrocardiographic measurement by the measuring device 4 becomes possible. In addition, stable electrocardiographic measurement is possible without preparing a member (eg, gel) for separately supplying water to the contact portion.

In particular, when the measurement target is an animal that does not sweat (eg dog), or when the electrocardiographic measurement is performed in an environment where the humidity is relatively low (eg winter), the water content of the contact portion is relatively high. Since it is small, the contact resistance tends to increase. Especially in the case of animals that do not sweat, it is difficult to stably measure the electrocardiogram because the measurement site dries quickly in the case of discontinuous hydration. By using the electrode structure 1 for the electrocardiographic measurement, as described above, water can be continuously and stably supplied to the contact portion, so that the electrocardiographic measurement of a sweat-free animal or the humidity is relatively low. Stable measurement is possible even for electrocardiographic measurement in a small environment. That is, the electrode structure 1 can be particularly effectively used when the measurement target is an animal that does not sweat, or when the electrocardiographic measurement is performed in an environment where the humidity is relatively low.

The water supply material 122 is arranged in the vicinity of the electrode 11, and in the present embodiment, the water supply material 122 is arranged at a position facing the inner surface 11b of the electrode 11. That is, the water supply material 122 is arranged below the electrode 11. By attaching the fitting 2 to the dog or by breathing the dog, a force is applied to the water supply material 122 in the direction from the electrode structure 1 toward the measurement site or in the opposite direction. In the present embodiment, since the electrode 11 and the water supply material 122 are provided along the direction thereof, water is supplied from the water supply material 122 to the electrode 11 by the above-mentioned force. Therefore, since the water supply material 122 is arranged at the above position, water can be efficiently supplied to the electrode 11.

Further, the storage material 121 is formed with an opening 121a at a position facing the electrode 11. Therefore, for example, when the fitting 2 is attached to the dog, the water supply material 122 and the inner surface 11b of the electrode 11 can be brought into direct contact with each other, so that water can be efficiently supplied to the electrode 11.

Note that the electrode structure 1 may have at least a water supply material 122 in order to continuously and stably supply water to the contact portion. The same applies not only to the first embodiment but also to the modified examples and other embodiments.

The waterproof material 123 functions as a water supply suppressing material that reduces the possibility that the water retained in the water supply material 122 is supplied to other than the electrode 11 or the measurement site. As a result, the water retained by the water supply material 122 can be diffused to a member existing in a place other than the above (example: a part other than the electrode 11 in the electrode structure 1, a body surface other than the measurement part, a fitting 2). The sex can be reduced. Therefore, water can be efficiently supplied from the water supply material 122 to the electrode 11 or the measurement site. Therefore, more stable water supply to the electrode 11 or the measurement site becomes possible. Examples of the waterproof material 123 include a waterproof material such as a waterproofed cloth or a sheet, or a breathable waterproof material.

The waterproof material 123 is arranged in the vicinity of the water supply material 122. Specifically, the waterproof material 123 is arranged on the side of the water supply material 122 opposite to the body surface with which the electrode structure 1 abuts. In the present embodiment, the waterproof material 123 is provided at a position adjacent to the water supply material 122 (at a position of the water supply material 122 opposite to the surface facing the electrode 11 and directly below the water supply material 122).

Note that the storage material 121 may be realized with a waterproof material. That is, the storage material 121 may function as the waterproof material 123. If the material of the storage material 121 is a material that absorbs water, the water content of the water supply material 122 may travel along the storage material 121 and move below it (eg, the elastic material 124 and the fitting 2). There is. By realizing the storage material 121 with a waterproof material, the possibility that such movement will occur can be reduced, so that the water supply from the water supply material 122 to the electrode 11 can be more efficiently supplied.

However, if the storage material 121 is made of a waterproof material, it will be difficult to ensure breathability. When the fitting 2 is washed and used, the inside of the storage material 121 becomes difficult to dry after washing. Therefore, from the viewpoint of hygiene, it is preferable that the storage material 121 is realized by a cloth or the like which is not waterproofed and whose breathability can be easily ensured. For example, in the storage material 121, the waterproof material may be used only in the portion facing the elastic material 124. Further, the waterproof material may be used on the entire surface of the mounting tool 2 or on the back surface of the electrode structure 1 (the surface facing the mounting tool 2). As a result, it is possible to reduce the possibility that water will flow out from the fitting 2 to the outside.

The elastic material 124 expands and contracts in the direction in which the electrode 11 comes into contact with the measurement site and in the opposite direction. That is, the elastic material 124 expands and contracts in the direction in which the force is applied. Further, the elastic material 124 is arranged on the side facing the inner surface 11b of the electrode 11, and expands and contracts in the above direction with the application of the above force. Therefore, since the thickness of the electrode structure 1 can be changed by applying the above force, the electrode 11 and the measurement site can be brought into close contact with each other with a certain force. Therefore, the measuring device 4 can accurately acquire the signal indicating the electrocardiogram from the electrode 11. The elastic material 124 does not have to be particularly conductive. When the elastic material 124 has conductivity, the electrical noise generated when the elastic material 124 expands and contracts may hinder the stable measurement of the electrocardiogram.

In the present embodiment, elastic sheets 124a to 124d (sheets) having elasticity are laminated as the elastic material 124. In this case, the thickness of the electrode structure 1 can be changed only by changing the number of elastic sheets 124a to 124d provided on the electrode structure 1. That is, when the elastic material 124 includes the elastic sheets 124a to 124d, the thickness thereof can be easily adjusted.

In 1002 of FIG. 1, four elastic sheets 124a to 124d are provided as the elastic member 124, but one to three or five or more elastic sheets are provided. Is also good. That is, the elastic material 124 may be composed of one or a plurality of elastic sheets. Further, the elastic material 124 may be a member having elasticity, for example, a spring.

Here, the condition of hair (eg, length, quantity, hair quality) may differ from dog to dog (eg, depending on the type of dog). Therefore, for example, the more hair the dog has, the larger the step between the hair-cutting portion as the measurement site and the non-hair-cutting portion around the measurement site. Even if the hair around the measurement site is pressed by attaching the fitting 2 to the dog, if the thickness of the electrode structure 1 is smaller than the step, the electrode 11 cannot be sufficiently brought into close contact with the measurement site. There is sex. On the other hand, if the thickness of the electrode structure 1 is larger than the step, an excessive force is applied from the electrode structure 1 to the measurement site, and the dog dislikes the contact of the electrode structure 1. May show a feeling. In this case, the dog may scratch the electrode structure 1 and interfere with the measurement of the electrocardiogram. In addition, if the dog scratches the measurement site, the body surface, which is the measurement site, may be damaged.

Therefore, by preparing a plurality of electrode structures 1 in which the thickness of the elastic material 124 is changed, the electrode 11 can be brought into close contact with the measurement site with an appropriate force for each dog. Therefore, the electrode structure 1 can stably acquire a signal indicating electrocardiography in dogs having different hair states without damaging the body surface.

For example, for a dog with relatively little hair (a dog with a relatively small step), the electrode 11 can be brought into close contact with the measurement site with an appropriate force by setting the thickness of the elastic material 124 to about 5 mm. For dogs with relatively large hair (dogs with a relatively large step), the thickness of the elastic material 124 is set to about 3 cm so that the electrode 11 can be brought into close contact with the measurement site with an appropriate force. That is, the thickness of the elastic material 124 can be set to, for example, 5 mm or more and 3 cm or less.

<Modification example>
FIG. 3 is a cross-sectional view of the electrode structure 1A, which is a modified example of the electrode structure 1. In the storage material 121 of the electrode structure 1 shown in FIG. 1, an opening 121a is formed in a region facing the inner surface 11b of the electrode 11. The electrode structure 1A shown in FIG. 3 is different from the electrode structure 1 in that the opening 121a is not formed in the storage material 121. That is, in the electrode structure 1, the electrode 11 and the storage material 121 cover the internal member of the storage material 121, but in the electrode structure 1A, only the storage material 121 covers the internal member.

In the case of the electrode structure 1A, since the storage material 121 also exists in the above region, the strength of the electrode structure 1A can be improved. However, in the case of the electrode structure 1A, at least in the above region, the storage material 121 is made of a material (eg, cloth) that allows moisture to pass from the water supply material 122 to the electrode 11. On the other hand, since the electrode structure 1 has an opening 121a formed and the electrode 11 and the water supply material 122 are in direct contact with each other, it is easy to supply water to the electrode 11.

<Structure of health condition acquisition system>
FIG. 4 is a diagram showing a configuration example of a health state acquisition system 200 including the measuring device 4 according to the present embodiment. The health condition acquisition system 200 is a system for acquiring the health condition of a dog.

As shown in FIG. 4, when the fitting 2 is attached to the dog, a storage portion 21 accommodating the measuring device 4 is arranged on the back side of the dog, and the electrode structure 1 (is on the chest side of the dog). The electrode 11) is arranged.

In the health state acquisition system 200, the measuring device 4 acquires, for example, a signal indicating the dog's electrocardiogram from the electrode 11, and performs signal processing and calculation on the signal to perform pulsation interval of the dog's heart. Is extracted. Further, in the example shown in FIG. 4, the measuring device 4 may extract the breathing interval of the dog by acquiring the corresponding signal by, for example, an acceleration sensor, and performing signal processing and calculation on the signal.

The beat interval and respiration interval data extracted by the measuring device 4 are transmitted wirelessly (eg, BLE) to the data analysis / display device 70 (external analysis device described above). The data analysis / display device 70 may be, for example, a smartphone or a tablet. In addition, the measuring device 4 may also transmit the body temperature of the dog measured by the temperature / humidity sensor (body surface temperature sensor) to the data analysis / display device 70. The data analysis / display device 70 analyzes the received data and derives the heart rate and the respiratory rate. In addition, the data analysis / display device 70 may derive other indexes that can be derived from the data of the beat interval, the respiration interval, and the body temperature. Further, the data analysis / display device 70 displays the derived heart rate and respiratory rate, and transmits the data of the heart rate, respiratory rate, and body temperature to the cloud server 80. The cloud server 80 stores heart rate, respiratory rate and body temperature data.

The method of transmitting data to the cloud server 80 is not limited to the method via the data analysis / display device 70. For example, the measuring device 4 is provided with a communication device (eg, a wireless communication device connected to a wireless LAN (Local Area Network)) that can directly access the Internet line, and data indicating the heart rate and respiratory rate is directly transmitted to the cloud server 80. You may. In this case, the cloud server 80 can analyze the received data to calculate the heart rate and the respiratory rate.

[Embodiment 2]
Other embodiments of the present disclosure will be described below. For convenience of explanation, the same reference numerals will be added to the members having the same functions as the members described in the above embodiment, and the description will not be repeated. The same applies to the subsequent embodiments. The electrode structures 1B and 1C shown in FIGS. 5 and 6 may have a configuration in which the storage material 121 does not have the opening 121a, as in the electrode structure 1A which is a modification of the first embodiment. The same applies to the electrode structure 1D of the third embodiment (see FIG. 7) and the electrode structures 1E to 1H of the fourth embodiment (see FIGS. 8 to 11).

<Electrode structure 1B>
5 and 5002 of FIG. 5 are cross-sectional views of the electrode structure 1B. The electrode structure 1B is different from the electrode structure 1 of FIG. 1 in that the storage material 121 is provided with an opening 125.

As shown in 5001 and 5002 of FIG. 5, the storage material 121 of the electrode structure 1B is formed with an opening 125 that enables access to the members housed inside the storage material 121. In 5001 of FIG. 5, the members are a water supply material 122, a waterproof material 123, and an elastic material 124. Further, the opening 125 is formed at the bottom of the storage material 121 (the side facing the mounting tool 2) along the depth direction of the paper surface. Further, the opening 125 has substantially the same length as the side of the storage material 121 extending along the direction. However, the opening 125 may have a shape and a size that allows access to the member housed inside the storage material 121. For example, the opening 125 may be formed at the bottom of the storage material 121 along a direction other than the depth direction of the paper surface, or may be shorter than the side of the storage material 121. Further, the opening 125 may be provided in a portion other than the bottom portion of the storage material 121 (example: see FIG. 6).

Since the opening 125 is formed in the storage material 121, it is possible to replace the internal member of the storage material 121. When the water supply material 122 is stored inside the storage material 121, for example, by inserting a dropper or the like into the opening 125 at the start of electrocardiographic measurement, water is supplied to the water supply material 122 without taking out the water supply material 122. Can be supplied. Further, for example, at the start of electrocardiographic measurement, water can be supplied to the water supply material 122 after the water supply material 122 is taken out through the opening 125. Further, by making the above-mentioned member replaceable, when the water supply material 122, the waterproof material 123 or the elastic material 124 deteriorates, the deteriorated member can be replaced. Further, when the water supply material 122, the waterproof material 123, or the elastic material 124 is in a state where fungi such as mold are present, the member having the fungus can be replaced. Therefore, continuous electrocardiographic measurement or hygienic wearing tool 2 can be realized.

Further, when the elastic material 124 is realized by the elastic sheet (reference numerals 124a to 124d in FIG. 1), the elastic sheet can be inserted or removed through the opening 125. Therefore, the thickness of the electrode structure 1B can be changed by adjusting the number of elastic sheets inserted into the storage material 121.

As described above, if the thickness of the electrode structure 1 is not adjusted appropriately, the electrode 11 may not be sufficiently brought into close contact with the measurement site, the electrocardiographic measurement may be hindered, or the body surface may be damaged. There is a possibility that it will end up. By forming the opening 125 in the storage material 121, the thickness of the electrode structure 1B can be easily changed by inserting and removing the elastic sheet each time the attachment 2 is attached to the dog. Therefore, the occurrence of the above possibility can be reduced. That is, the electrode structure 1B can stably acquire a signal indicating electrocardiography in dogs having different hair states without damaging the body surface.

Further, as shown in 5002 of FIG. 5, an opening 23 having the same function as the opening 125 may be formed at a position of the fitting 2 facing the opening 125. In this case, the user can access the member housed inside the storage material 121 without removing the electrode structure 1B from the fitting 2.

<Electrode structure 1C>
FIG. 6 is a cross-sectional view of the electrode structure 1C. As shown in FIG. 6, the electrode structure 1C is different from the electrode structure 1B of FIG. 5 in that an opening 125 is formed on the side portion of the storage material 121. By forming the opening 125 on the side portion of the storage material 121, the user can access the member housed inside the storage material 121 without removing the electrode structure 1C from the fitting 2. Become.

[Embodiment 3]
FIG. 7 is a cross-sectional view of the electrode structure 1D. As shown in FIG. 7, the electrode structure 1D includes an electrode 11 and an electrode holding portion 12D. The electrode holding portion 12D is different from the electrode structure 1 of FIG. 1 in that the elastic member 126 and the hollow member 127 are provided in place of the elastic member 124 included in the electrode holding portion 12 of FIG.

The elastic material 126 can contain a gas (eg, air) and expands and contracts depending on the amount of the contained gas. The elastic material 126 is, for example, a balloon made of rubber, but is not limited to this as long as it is a member that can be expanded and contracted by gas. The hollow member 127 is a member that is connected to the elastic member 126 and enables gas to be inserted or released from the elastic member 126. The hollow member 127 is inserted into through holes provided in each of the storage material 121 and the expansion / contraction material 126. The hollow member 127 may be provided with a stopper (not shown) for stopping the insertion or release of gas.

Thereby, the amount of gas contained in the elastic member 126 can be changed through the hollow member 127. Specifically, the elastic material 126 can be thickened by inserting gas from the outside of the storage material 121 into the inside of the elastic material 126 through the hollow member 127. On the other hand, the elastic material 126 can be made thin by releasing gas from the inside of the elastic material 126 to the outside of the storage material 121 through the hollow member 127. By changing the thickness of the elastic material 126 in this way, the thickness of the electrode structure 1D can be changed. Therefore, since the thickness of the electrode structure 1D can be easily changed according to the state of the body hair, the electrode structure 1D can stably acquire a signal indicating an electrocardiogram regardless of the state of the body hair.

[Embodiment 4]
The electrode structure 1 (see FIG. 1) of the first embodiment has a structure in which the electrode 11 and the water supply material 122 are laminated, but the structure is not limited to this. For example, when viewed from the surface side of the electrode structure in contact with the measurement site (that is, when viewed from the outer surface 11a side, in other words, when viewed in a plan view), the water supply material 122 is provided around the electrode 11. Is also good. Hereinafter, as a configuration example of such an electrode structure, for example, FIGS. 8 to 11 will be described.

The electrode structures 1E to 1H shown in FIGS. 8 to 11 have an opening 125 formed as in the electrode structure 1B (see FIG. 5) and the electrode structure 1C (see FIG. 6) of the second embodiment. You may. Further, the electrode structures 1E to 1H may be provided with the elastic member 126 and the hollow member 127 as in the electrode structure 1D (see FIG. 7) of the third embodiment. Further, the electrode structures 1E to 1H may be provided with a water supply material 122 and / or a waterproof material 123 inside the storage material 121 as in the electrode structure 1 of the first embodiment.

<Electrode structure 1E>
FIG. 8 is a diagram showing a configuration example of the electrode structure 1E. 8001 of FIG. 8 is a plan view of the electrode structure 1E, and 8002 of FIG. 8 is a cross-sectional view of the electrode structure 1E.

As shown in 8002 of FIG. 8, the electrode structure 1E includes an electrode 11 and an electrode holding portion 12E. The electrode holding portion 12E includes a storage material 121, a waterproof material 123, and an elastic material 124. The electrode holding portion 12E is different from the electrode structure 1 of the first embodiment (see FIG. 1) in that the water supply material 122 is not provided.

In the electrode holding portion 12E, the waterproof material 123 is provided on the storage material 121. That is, the storage material 121 includes only the elastic material 124 inside. The storage material 121 and the waterproof material 123 are connected by being sewn with, for example, a thread. In this example, the waterproof material 123 is provided all over the storage material 121, but it may be large enough to reduce the possibility that the water content of the water supply material 122 is supplied to the storage material 121 side. ..

Further, in the electrode structure 1E, as shown in 8001 and 8002 of FIG. 8, the water supply material 122 is arranged on the electrode holding portion 12E over the entire circumference of the electrode 11 when viewed in a plan view. Specifically, a layer including the electrode 11 and the water supply material 122 is provided on the surface of the waterproof material 123 opposite to the surface connected to the storage material 121 (immediately above the waterproof material 123). That is, together with the electrode 11, the contact surface 122a is in direct contact with the measurement site or the periphery of the measurement site. Even when the water supply material 122 is arranged in this way, the water content of the water supply material 122 can be supplied to the electrode 11 or the measurement site (that is, the contact portion thereof). The electrode 11, the water supply material 122, and the waterproof material 123 are connected by, for example, sewing a thread. The porous body contained in the water supply material 122 is arranged on the peripheral edge of the electrode 11.

In this example, the water supply material 122 and the waterproof material 123 have the same shape when viewed in a plan view, but the present invention is not limited to this. For example, the waterproof material 123 may be provided so as to surround the water supply material 122. In this case, the possibility that the water content of the water supply material 122 is supplied to the fitting 2 side can be further reduced. The size or shape of the waterproof material 123 may be such that the possibility that the water content of the water supply material 122 is supplied to the storage material 121 side can be reduced.

Although the water supply material 122 is provided on the waterproof material 123 so as to be in contact with the electrode 11, the water supply material 122 may be provided so as to be separated from the electrode 11. The relative positional relationship between the electrode 11 and the water supply material 122 may be any positional relationship that allows the water content of the water supply material 122 to be supplied to the electrode 11 or the measurement site when the fitting 2 is attached to the dog.

Further, a through hole is provided in the portion of the waterproof material 123 facing the electrode 11 so that the lead wire 3 can be electrically connected to the electrode 11. However, with the lead wire 3 electrically connected to the electrode 11 sandwiched between the electrode 11, the water supply material 122, and the waterproof material 123, the electrode 11, the water supply material 122, and the waterproof material 123 are inserted. When connecting, the through hole is unnecessary. Further, in this case, a through hole for taking out the lead wire 3 from the inside of the storage material 121 is also unnecessary.

<Electrode structure 1F>
FIG. 9 is a diagram showing a configuration example of the electrode structure 1F. 9001 of FIG. 9 is a plan view of the electrode structure 1F, and 9002 of FIG. 9 is a cross-sectional view of the electrode structure 1F.

As shown in 9002 of FIG. 9, the electrode structure 1F includes an electrode 11 and an electrode holding portion 12F. The electrode holding portion 12F has the same structure as the electrode holding portion 12E shown in 8002 of FIG. 8, and the electrode 11 and the water supply material 122 are provided on the electrode holding portion 12F.

In the electrode structure 1E shown in FIG. 8, the water supply material 122 was arranged over the entire periphery of the electrode 11 when viewed in a plan view, but as shown in 9001 of FIG. 9, the periphery of the electrode 11 when viewed in a plan view. The water supply material 122 may be provided as a part of the water supply material 122. Even when the water supply material 122 is arranged in this way, the water content of the water supply material 122 can be supplied to the electrode 11 or the measurement site.

In FIG. 9, the water supply material 122 is provided at a position facing substantially the center of each side of the electrode 11 (provided at a total of four locations). However, the water supply material 122 may be provided so as to face at least one side of the electrode 11 and / or at least one corner. Further, a plurality of water supply materials 122 may be arranged on each side. Further, although the water supply material 122 is provided so as to be separated from each side of the electrode 11, it may be provided so as to come into contact with each other. The arrangement position of the water supply material 122 and the relative positional relationship between the electrode 11 and the water supply material 122 can supply the water content of the water supply material 122 to the electrode 11 or the measurement site when the fitting 2 is attached to the dog. It may be in a positional relationship.

Further, as shown in 9002 of FIG. 9, the thickness of the water supply material 122 is thicker than that of the electrode 11. When the water supply material 122 is arranged on a part around the electrode 11 when viewed in a plan view, the water supply amount (water absorption amount) of the entire water supply material 122 is lower than that when the water supply material 122 is arranged over the entire periphery thereof. .. As the thickness of the water supply material 122 is thicker, the amount of water supplied to the water supply material 122 can be increased, so that the possibility that the water supply amount decreases as the arrangement area of the water supply material 122 decreases can be reduced. The thickness and size of one water supply material 122 is such that the water supply material 122 as a whole can supply water to the electrode 11 or the measurement site for the above-mentioned predetermined time and does not dislike the dog. All you need is.

Here, in 2002 of FIG. 2, when the attachment 2 is attached to a dog, it is in a state of being curved in the direction of the AA line. Therefore, when the water supply material 122 is provided along the AA line on the outside of the electrode 11 when viewed in a plan view, the contact surface 122a is arranged with the electrode 11 in the state where the fitting 2 is attached to the dog. You will be facing the direction you are in. That is, the water content of the water supply material 122 can be easily supplied to the electrode 11 or the measurement site side. From this point of view, the water supply material 122 may be provided around the electrode 11 in a plan view along the line AA shown in 2002 in FIG. In 9001 of FIG. 9, the arrangement positions along the AA line are indicated by the reference numerals Po1 and Po2.

<Electrode structure 1G>
FIG. 10 is a diagram showing a configuration example of the electrode structure 1G. 10001 is a plan view of the electrode structure 1G, and 10002 of FIG. 10 is a cross-sectional view of the electrode structure 1G.

The electrode structure 1G includes an electrode 11 and an electrode holding portion 12G, as shown in 10002 of FIG. The electrode holding portion 12G includes a storage material 121 and an elastic material 124. The electrode holding portion 12G is different from the electrode holding portion 12E of the electrode structure 1E and the electrode holding portion 12F of the electrode structure 1F in that only the electrode 11 is held on the upper surface thereof.

As shown in 10001 and 10002 of FIG. 10, the electrode structure 1G is provided with water supply materials 122 on both sides of the electrode 11 when viewed in a plan view. The porous body contained in the water supply material 122 is arranged on the peripheral edge of the electrode 11. In this example, the water supply material 122 has substantially the same thickness as the thickness of the storage material 121, and is provided at a position adjacent to the storage material 121.

In addition, a waterproof material 123 is provided around the water supply material 122. Specifically, the waterproof material 123 is provided so as to cover the surface of the water supply material 122 other than the contact surface 122a. As a result, the possibility that the water content of the water supply material 122 is supplied to the fitting 2 and the storage material 121 side can be reduced. Although the waterproof material 123 is connected to the storage material 121, it may be provided apart from the storage material 121.

It is not always necessary that the waterproof material 123 is provided so as to cover the entire surface of the water supply material 122 other than the contact surface 122a. The waterproof material 123 is, for example, one of the side surface of the water supply material 122 opposite to the contact surface 122a (the surface side facing the fixture 2) and the side surface of the water supply material 122 (the surface other than the contact surface 122a and the opposite surface). It may be provided in the part. In other words, the waterproof material 123 is provided at least on the side opposite to the body surface with which the electrode structure 1G abuts. That is, the waterproof material 123 may be provided so as to reduce the possibility that the water retained in the water supply material 122 is supplied to other than the electrode 11 or the measurement site.

The relative positional relationship between the electrode 11 and the waterproof material 123 (water supply material 122) is such that when the attachment 2 is attached to the dog, the water content of the water supply material 122 can be supplied to the electrode 11 or the measurement site. Just do it. The thickness and size of one water supply material 122 may be such that the water supply material 122 as a whole can supply water to the electrode 11 or the measurement site for the predetermined time.

Further, the bottom of the waterproof material 123 may be provided with, for example, a hook-and-loop fastener as in the case of the bottom of the storage material 121. In this case, the electrode structure 1G can be removed from the fitting 2. The storage material 121 and the waterproof material 123 may be connected so as to be separated from each other by, for example, a hook-and-loop fastener. In this case, the relative positional relationship between the electrode 11 and the water supply material 122 can be easily changed. Further, the storage material 121 may be detachably connected to the attachment 2 and the waterproof material 123, and the connection position of the waterproof material 123 may be fixed to the attachment 2. When the storage material 121 is formed with the opening 125 as in the second embodiment, the user can easily insert or remove the elastic material 124 by removing the storage material 121 from the fitting 2.

Further, in consideration of the shape of the attachment 2 when attached to the dog, the water supply material 122 is provided along the line AA shown in 2002 in FIG. As a result, even if the water supply material 122 is provided on a part around the electrode 11 when viewed in a plan view, the water supply to the electrode 11 or the measurement site can be efficiently performed.

However, if the above-mentioned efficient water supply is not taken into consideration, the water supply material 122 does not necessarily have to be provided along the AA line, for example, a straight line adjacent to the electrode holding portion 12G and orthogonal to the AA line. It may be provided at a position along the above. Further, the water supply material 122 may be provided only on one side of the electrode 11 when viewed in a plan view, or may be provided at four positions facing all sides of the electrode 11.

<Electrode structure 1H>
FIG. 11 is a diagram showing a configuration example of the electrode structure 1H. 11001 of FIG. 11 is a plan view of the fitting 2 when the fitting 2 is viewed from the inside. 11002 of FIG. 11 is a sectional view taken along line BB of the fitting 2.

As shown in 11002 of FIG. 11, the electrode structure 1H includes an electrode 11 and an electrode holding portion 12H. The electrode holding portion 12H has the same structure as the electrode holding portion 12G shown in 10002 of FIG. 10, and the electrode 11 is provided on the upper surface thereof.

As shown in 11001 and 11002 in FIG. 11, the electrode structure 1H is provided with a water supply material 122 around the electrode 11 when viewed in a plan view. The water supply material 122 is provided as a common water supply material for the two electrode structures 1H. Even in this case, the water content of the water supply material 122 can be supplied to each of the electrodes 11 included in the two electrode structures 1H or to the measurement sites facing each of the two electrode structures 1H.

Further, the waterproof material 123 is provided at a position (directly below the water supply material 122) of the water supply material 122 facing the surface (opposite surface) opposite to the contact surface 122a. As a result, the possibility that the water content of the water supply material 122 is supplied to the fitting 2 side can be reduced.

The water supply material 122 is connected to the waterproof material 123. Although the waterproof material 123 is connected to the storage material 121, it may be provided apart from the storage material 121. Further, as in the electrode structure 1G of FIG. 10, for example, a hook-and-loop fastener may be provided on the bottom of the waterproof material 123 or on the side portion connected to the storage material 121. Further, the waterproof material 123 may be larger than the water supply material 122 when viewed in a plan view, or may be provided so as to surround the water supply material 122 as in the electrode structure 1G.

The positional relationship between the electrode 11 and the water supply material 122 may be any positional relationship in which the water content of the water supply material 122 can be supplied to the electrode 11 or the measurement site. The thickness and size of the water supply material 122 may be such that the water can be supplied to the electrode 11 or the measurement site for the predetermined time.
