Description

One aspect of the present disclosure relates to an electrode structure electrically connected to a measuring device that measures biological information of an animal.

A structure of a biomedical electrode for measuring biomedical information is disclosed in Patent Document 1, for example.

As a result, the biomedical electrode can be brought into close contact with the living body regardless of the measurement site.

JP 2011-36524 A

In general, the smaller the amount of water in the measurement site, the greater the contact resistance between the measurement site and the biomedical electrode. When the contact resistance increases, it becomes impossible to measure biological information. Patent Literature 1 does not disclose biometric information measurement in consideration of an increase in contact resistance.

An object of one aspect of the present disclosure is to realize an electrode structure or the like capable of stably measuring biological information.

[Embodiment 1]
An embodiment of the present disclosure will be described in detail below.

<Composition of wearing equipment>
2001 and 2002 in FIG. 2 are plan views showing an example of the wearing tool 2 when the wearing tool 2 is viewed from the inside. 2003 in FIG. 2 is a sectional view taken along the line AA in 2002 in FIG. 2002 in FIG. 2 shows a state in which the portion of the wearing device 2 provided with the storage portion 21 is folded back. The inner side (back side) of the harness 2 is the side that contacts the dog when the harness 2 is attached to the dog, and the outer side (front side) of the harness 2 is the side that does not contact the dog. .

As shown in 2001 to 2003 in FIG. 2, the harness 2 is worn by a dog and includes an electrode structure 1, a lead wire 3, a housing 21, and a button 22. As shown in FIG.

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

With the harness 2 wrapped around the dog, the first end provided with the storage portion 21 and the second end provided with no storage portion 21 are detachably connected. The inner portion of the first end and the outer portion of the second end are provided with hook-and-loop fasteners, for example. By connecting the first end and the second end at the dog's back, the measuring device 4 is placed on the dog's back and the electrode structure 1 is brought into contact with the dog's chest side. Thus, the harness 2 can be worn on the dog. In other words, the electrode structure 1 is arranged at a position where the electrodes 11 of the harness 2 come into contact with the chest side of the dog when the harness 2 is worn on the dog.

At least part of the fitting 2 is made of a material having flexibility (stretchability). In this case, the harness 2 can be fitted regardless of the body shape (posture) of the dog, so that the electrode structure 1 can be pressed against the dog's chest side with an appropriate force to bring it into close contact. When the pressing force is too strong, the force can be reduced by extending the surface of the attachment 2 covering the electrode structure 1 .

The first end and the second end (that is, the dog's back) can be secured by using a flexible material for the attachment 2 and by providing hook-and-loop fasteners at the first end and the second end. , the tightening force of the harness 2 to the dog can be adjusted. The hook-and-loop fastener is installed with a predetermined length or longer, for example, 1 cm or longer, in the dog's waist direction. It is possible to adjust the length of the waist of the wearing tool 2 and change the tightening force by the fastening position where the hook-and-loop fastener is fastened. A member that can adjust the tightening force may be provided at the first end and the second end, and examples of the member include a hook-and-loop fastener, a buckle, a belt, a button, a string, or a belt. .

Note that the wearing tool 2 does not necessarily have to be a belt-like member, and may be wear that can be worn through the forefoot, for example. In addition, although the storage portion 21 is provided at the first end, it is not limited to this, and one electrode structure 1 may be provided at the first end and the other electrode structure 1 may be provided at the second end. do not have. In this case, the first end and the second end are connected near the chest side of the dog. When the harness 2 is worn on the dog, if the electrode structure 1 is arranged on the harness 2 so as to abut on the chest side of the dog, the electrode structure 1 and the housing can be placed at any position on the harness 2. A portion 21 may be provided.

Further, as the harness 2, there are a plurality of types of harnesses having different sizes (lengths) from each other in order to ensure close contact with the dog at the time of wearing, so as to correspond to various types of dogs or differences in physique. 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 attachment 2 so as to abut against the dog's chest side. The electrode structure 1 is electrically connected to the measuring device 4 and has an electrode 11 that is brought into contact with the body surface of the dog (the measurement site on the side of the chest). The measurement site is the body surface (hair-cut site) on the side of the chest where the body hair is shaved, and is the part where the electrode 11 is brought into contact. By using the shaved portion as the measurement portion in this way, the contact resistance between the electrode 11 and the measurement portion can be reduced by increasing the accuracy with which the electrode 11 contacts the measurement portion. A specific structure of the electrode structure 1 will be described later.

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

The electrode 11 internally has a structure (eg, a porous structure having minute holes) that allows passage of water supplied from the water supply material 122 (see FIG. 1). In other words, a hole is formed inside the electrode 11 to allow the moisture to pass therethrough. As a result, the moisture 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 water, a liquid having a certain amount or more of electrolyte, such as tap water or salt water, is used. As moisture, 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 structure described above include conductive cloth. As long as the electrode 11 has the structure described above, the material of the electrode 11 is not limited to conductive cloth, and may be a conductive material such as a metal, a conductive polymer, or a conductive carbon. can be The timing for supplying water to the water supply material 122 may be appropriately set by the user using the measuring device 4 . The water supply material 122 may be dry when the measurement device 4 is not used for measurement.

When a conductive cloth, for example, is used as the material of the electrode 11, the electrode 11 has flexibility (flexibility). In this case, even if the harness 2 is curved according to the body shape of the dog when the harness 2 is worn on the dog, the shape of the electrode 11 can be changed according to the curve. Therefore, it is possible to reduce the possibility that the measurement site is damaged due to contact of the electrode 11 with the measurement site.

As described above, body hair at and around the measurement site is shaved to reduce the contact resistance between the electrode 11 and the measurement site. At this time, using a shaving attachment having substantially the same shape as the attachment 2 and having openings formed in the attachment 2 at positions corresponding to the positions where the electrodes 11 are arranged, the measurement site and the Body hair around it may be shaved. By using the shaving attachment, it is possible to accurately and easily shave the measurement site with which the electrode 11 abuts and the surrounding body hair. Further, when a plurality of types of attachment tools 2 having different sizes are prepared according to the type of dog, etc., a shaving attachment tool may be prepared for each size of the attachment tool 2 . In this case, it is possible to accurately and easily shave the body hair according to a plurality of types of wearing tools 2 .

A conducting wire 3 is a signal wire that electrically connects the measuring device 4 connected to the button 22 and the two electrodes 11 . Specifically, the conductor 3 has one end electrically connected to the electrode 11 and the other end electrically connected to the button 22 . The conductor 3 thereby outputs a signal indicative of the dog's electrocardiogram 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 housing portion 21 and electrically connected to a button 22 (a conductive button) provided in the housing portion 21 . Each of the two buttons 22 is connected to a conductor 3 that is connected to each of the two electrodes 11 . Therefore, by electrically connecting the measuring device 4 to the button 22, the signal indicating the electrocardiogram of the dog obtained from the dog can be processed. 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 the function of analyzing the signal. The measuring device 4 measures the dog's electrocardiogram by detecting the potential difference between the respective electrodes 11 .

The measurement device 4 includes, for example, a battery, an electrocardiographic signal processing circuit, and a microcomputer to perform the signal processing and/or analysis described above. The electrocardiogram signal processing circuit and the microcomputer are mounted on a board that can be electrically connected to the button 22, for example. In addition, the measuring device 4 may have an acceleration sensor or a temperature/humidity sensor mounted on the substrate. If the measuring device 4 has a function of transmitting the processed signal to an external analysis device, for example, it is equipped with a communication module (eg, BLE (Bluetooth (registered trademark) Low Energy) module) equipped with an antenna. Also good. In this case, the measurement device 4 can send the processed signal to an external analysis device by means of the BLE module.

Further, the biological information to be measured by the measuring device 4 is not limited to electrocardiogram, and may be any information such as heart rate, body temperature, blood sugar level, and the like. 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-like member that stores the measuring device 4 inside. In other words, the storage part 21 forms a space for storing the measuring device 4 . The storage part 21 is provided outside the wearing tool 2 and at the first end of the wearing tool 2 . The storage part 21 is arranged on the dog's back side when the dog is fitted with the harness 2. - 特許庁By arranging the storage section 21 on the back side of the dog, the possibility of the dog breaking the storage section 21 or the measuring device 4 stored therein with its paws or mouth can be reduced. Moreover, when the measuring device 4 is broken, the possibility that the broken measuring device 4 is broken and the dog is injured can be reduced. If this point is not considered, the storage part 21 may be provided at any position of the wearing tool 2 as described above. Moreover, the storage part 21 may be provided with a lid part for preventing the stored measurement device 4 from jumping out.

Button 22 is for electrically connecting lead 3 and measuring device 4 . 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 metal, conductive polymer, or conductive carbon. Alternatively, the button 22 may be a non-conductive button whose surface is covered with a material such as metal, conductive polymer, or conductive carbon. The button 22 is provided in a portion of the wearing tool 2 where the storage portion 21 is provided.

<Structure of electrode structure>
FIG. 1 is a diagram showing a configuration example of an electrode structure 1. FIG. 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. As shown in FIG. The electrode structure 1 includes an electrode 11 that is brought into contact with a measurement site (body surface on the chest side) and an electrode holder 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. Thereby, the shape of the electrode structure 1 can be changed according to the curvature of the attachment 2 regardless of the body shape of the dog. Therefore, the electrode 11 can be brought into close contact with the measurement site. The surface of the electrode structure 1 on which the electrode 11 is provided may have a curved shape with the electrode 11 as the vertex. In this case, it becomes easier to bring the electrode structure 1 into close contact with the measurement site.

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

In this embodiment, as indicated by 1001 in FIG. 1, the electrode 11 and the conducting wire 3 are fixed so as to be in surface contact with each other. Reference character Ar in FIG. 1 indicates a contact area between the electrode 11 and the conducting wire 3 . In the present embodiment, the conducting wire 3 is a conductive cloth, similar to the electrode 11, and is made of the same material as the electrode 11 (eg, silver-plated thread). Further, the conducting wire 3 has a length (for example, several tens of centimeters) that allows connection between the button 22 (see FIG. 2) and the electrode 11, and is long enough to make 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 conductor 3 is brought into contact with the inner surface 11b of the electrode 11, the electrode 11 and the conductor 3 are fixed (crimped, closely attached) by sewing together with a thread made of the same material. Thereby, the electrode 11 and the conducting wire 3 can be electrically connected while the resistance caused by the contact between the electrode 11 and the conducting wire 3 is reduced.

It is not always necessary to connect the electrodes 11 and the conducting wires 3 using threads of the same material, and they may be connected using threads of different materials or may be bonded using an adhesive or the like. The conductive wire 3 is not necessarily made of the same conductive cloth as the electrode 11, and may be made of a different conductive cloth. For example, it may be a cable), a conductive polymer, a conductive tape, or the like. Moreover, the electrode 11 and the conducting wire 3 may be a common member (the electrode 11 and the conducting wire 3 may be integrally formed).

However, the resistance value due to the contact between the electrode 11 and the conducting wire 3 is reduced to such an extent that the electrode 11 and the conducting wire 3 are electrically connected. Therefore, regardless of the materials or shapes of the electrodes 11 and the conductors 3, and the material (eg, thread, adhesive) for connecting the electrodes 11 and the conductors 3, the electrodes 11 and the conductors 3 are connected to the mounting device 2. The lead wire 3 is firmly fixed so as not to come off from the electrode 11 during use. Further, the electrode 11 and the conducting wire 3 are connected so that the resistance value per unit length of the electrode 11 or less or the resistance value per unit length of the conducting wire 3 or less at the connection portion thereof.

The electrode holding part 12 includes a storage member 121, a water supply member 122, a waterproof member 123, and an elastic member 124 in this embodiment. As indicated by 1002 in FIG. 1, in the electrode structure 1 of the present embodiment, the electrode 11, the water supply material 122, the waterproof material 123, and the stretchable material 124 are arranged in this order from the side contacting the measurement site. forming a structure.

The storage material 121 stores therein a water supply material 122, a waterproof material 123, and an elastic material 124. As shown in FIG. Although the material of the storage material 121 is not particularly limited, it is cloth, for example. 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 using thread. In addition, it is easy to ensure the air permeability inside the storage material 121 . Therefore, for example, after washing the attachment tool 2, the storage material 121 and the members stored inside the storage material 121 can be dried efficiently. Any material may be used for the storage material 121 unless this point is taken into consideration.

A through hole is formed in a part of the storage material 121 (the side part in the example of FIG. 1). The conducting wire 3 connected to the electrode 11 is taken out to the outside of the housing member 121 through this through hole. Outside the storage member 121, a shielding material 31 is provided around the conductors 3 so that the conductors 3 taken out from the two electrodes 11 are not electrically connected to each other. On the other hand, it is not always necessary to provide the shield material 31 around the conductor 3 inside the storage material 121 .

Also, the bottom of the storage material 121 may be detachably connected to the wearing tool 2 . For example, hook-and-loop fasteners are provided on the bottom of the storage member 121 and on the portion of the attachment 2 to which the electrode structure 1 is connected. This makes it possible to easily change the position of the electrode structure 1 on the mounting tool 2 .

The water supply material 122 supplies moisture to the electrode 11 or the measurement site. The water supply material 122 has a water absorption and retention function capable of retaining water for a predetermined period of time and a water supply function capable of supplying water to the electrode 11 or the measurement site while the harness 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 a porous structure, and is formed of a material capable of absorbing and retaining water within the structure. The material includes, for example, a mixed nonwoven fabric having a water-absorbing function, a water-absorbing polymer using a high-molecular material, or a sponge. Also, the water supply material 122 has a size and thickness that can realize the water supply holding function.

In this 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 the water supply material 122 can retain) 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.

Since water can be supplied to the electrode 11 by providing the water supply material 122 , water can be supplied to the measurement site through the electrode 11 . Moreover, 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, moisture can be supplied to the contact portion between the electrode 11 and the measurement site. Therefore, the contact resistance generated at the contact portion can be reduced. In addition, since the water supply material 122 is formed of, for example, the above material, it is possible to retain moisture for a predetermined period of time. Can supply parts. Therefore, since the signals from the electrodes 11 can be continuously and stably supplied to the measuring device 4, stable (continuous for a long time) electrocardiogram measurement by the measuring device 4 is possible. In addition, it is possible to stably measure the electrocardiogram without preparing in advance a member (eg, gel) for separately supplying moisture to the contact portion.

In particular, if the measurement target is an animal that does not sweat (e.g., dog), or if the electrocardiogram is measured in an environment with relatively low humidity (e.g., winter), the moisture content of the contact portion is relatively high. Since it is small, the contact resistance tends to increase. In particular, in the case of animals that do not sweat, in the case of non-continuous application of water, the measurement site dries up quickly, making it difficult to stably measure the electrocardiogram. By using the electrode structure 1 for electrocardiogram measurement, as described above, moisture can be continuously and stably supplied to the contact portion, so that electrocardiogram measurement of non-sweating animals or relatively humid animals can be performed. Even in electrocardiogram measurement in a small environment, stable measurement is possible. In other words, the electrode structure 1 can be used particularly effectively when the object to be measured is an animal that does not sweat, or when electrocardiographic measurement is performed in an environment with relatively low humidity.

The water supply material 122 is arranged in the vicinity of the electrode 11, and is arranged at a position facing the inner surface 11b of the electrode 11 in this embodiment. That is, the water supply material 122 is arranged under the electrode 11 . 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 by wearing the harness 2 on the dog or by breathing of the dog. In this embodiment, since the electrodes 11 and the water supply material 122 are provided along the direction, water is supplied from the water supply material 122 to the electrodes 11 by the above force. Therefore, by arranging the water supply material 122 at the above position, water can be efficiently supplied to the electrode 11 .

An opening 121 a is formed in the storage material 121 at a position facing the electrode 11 . Therefore, when the harness 2 is attached to a dog, for example, 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 supplied to the electrode 11 efficiently.

In addition, the electrode structure 1 only needs to have at least the water supply material 122 in order to continuously and stably supply moisture to the contact portion. The same applies not only to the first embodiment, but also to modifications and other embodiments.

The waterproof material 123 functions as a water supply suppressing material that reduces the possibility that water retained in the water supply material 122 is supplied to areas other than the electrode 11 or the measurement site. As a result, the moisture retained by the water supply material 122 can be diffused to members existing in locations other than the above (eg, portions other than the electrodes 11 in the electrode structure 1, the body surface other than the measurement site, and the wearing device 2). can reduce sex. 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 waterproof cloth or sheet, or a moisture-permeable waterproof material.

The waterproof material 123 is arranged near 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 this embodiment, the waterproof material 123 is provided at a position adjacent to the water supply material 122 (a position opposite to the surface of the water supply material 122 facing the electrode 11 and directly under the water supply material 122).

Note that the storage material 121 may be realized by 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 moisture, there is a possibility that the moisture of the water supply material 122 will travel through the storage material 121 and move downward (eg, the stretchable material 124 and the attachment 2). There is By realizing the storage material 121 with a waterproof material, the possibility of such movement can be reduced, so that it is possible to more efficiently supply water from the water supply material 122 to the electrodes 11 .

However, if the storage material 121 is made of a waterproof material, it becomes difficult to ensure breathability. When the mounting tool 2 is used after being washed, the inside of the storage material 121 becomes difficult to dry after washing. Therefore, from a hygienic point of view, it is preferable that the storage material 121 is made of non-waterproof cloth or the like, which can easily ensure air permeability. In addition, for example, in the storage member 121, only the portion facing the elastic member 124 may be made of a waterproof material. Also, the waterproof material may be used on the entire surface of the mounting device 2 or the back surface of the electrode structure 1 (the surface facing the mounting device 2). As a result, the possibility of water leaking from the wearing tool 2 to the outside can be reduced.

The elastic member 124 expands and contracts in the direction in which the electrode 11 is brought into contact with the measurement site and in the opposite direction. That is, the elastic member 124 expands and contracts in the direction in which the force is applied. Further, the elastic member 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 with the application of the force, the electrode 11 and the measurement site can be brought into close contact with each other with a certain amount of force. Therefore, the measuring device 4 can accurately acquire the signal indicating the electrocardiogram from the electrodes 11 . Elastic member 124 need not be particularly conductive. If the elastic member 124 is conductive, electrical noise generated when the elastic member 124 expands and contracts may interfere with stable electrocardiogram measurement.

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

1002 in FIG. 1 shows a configuration in which four elastic sheets 124a to 124d are provided as the elastic member 124, but a configuration in which one to three or five or more elastic sheets are provided. Also good. That is, the elastic member 124 can be composed of one or more elastic sheets. Moreover, the elastic member 124 may be any member having elasticity, and may be, for example, a spring.

Here, the state of body hair (eg, length, quantity, and quality of body hair) may vary from dog to dog (eg, dog type). For this reason, for example, the more hair a dog has, the greater the level difference between the shaved portion to be the measurement portion and the non-shorn portion around the measurement portion. Even if the attachment device 2 is attached to the dog and the body hair around the measurement site is pressed down, if the thickness of the electrode structure 1 is smaller than the height difference, the electrode 11 may not be brought into close contact with the measurement site. have a nature. On the other hand, if the thickness of the electrode structure 1 is greater than the step, the electrode structure 1 applies excessive force to the measurement site, and the dog dislikes contact with the electrode structure 1. can show feelings. In this case, the dog may scratch the electrode structure 1, which may hinder the measurement of the electrocardiogram. Moreover, there is a possibility that the body surface of the measurement site may be damaged by the dog scratching the measurement site.

Therefore, by preparing a plurality of electrode structures 1 in which the thickness of the elastic member 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 an electrocardiographic signal without damaging the body surface of dogs having different hair conditions.

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

<Modification>
FIG. 3 is a cross-sectional view of an electrode structure 1A that is a modification of the electrode structure 1. As shown in FIG. The housing member 121 of the electrode structure 1 shown in FIG. The electrode structure 1A shown in FIG. 3 is different from the electrode structure 1 in that the storage member 121 does not have the opening 121a. That is, in the electrode structure 1, the members inside the storage material 121 are covered with the electrodes 11 and the storage material 121, but in the electrode structure 1A, only the storage material 121 covers the internal members.

In the case of the electrode structure 1A, since the storage material 121 exists also 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 member 121 is made of a material (eg, cloth) that allows water to pass from the water supply member 122 to the electrode 11 . On the other hand, the electrode structure 1 has openings 121a and is structured such that the electrodes 11 and the water supply material 122 are in direct contact with each other.

<Configuration of health status acquisition system>
FIG. 4 is a diagram showing a configuration example of a health condition acquisition system 200 including the measuring device 4 according to this embodiment. The health condition acquisition system 200 is a system for acquiring the health condition of dogs.

As shown in FIG. 4 , the health condition acquisition system 200 includes a measuring device 4 , a data analysis/display device 70 and a cloud server 80 . As shown in FIG. 4, when the harness 2 is worn on the dog, the storage part 21 containing the measuring device 4 is arranged on the back side of the dog, and the electrode structure 1 ( An electrode 11) is arranged.

In the health condition acquisition system 200, the measuring device 4 acquires, for example, a signal indicating the electrocardiogram of the dog from the electrodes 11, and performs signal processing and calculation on the signal to determine the beating interval of the dog's heart. to extract Further, in the example shown in FIG. 4, the measuring device 4 may acquire a corresponding signal from an acceleration sensor, for example, and perform signal processing and calculation on the signal to extract the breathing interval of the dog.

The beat interval and breathing interval data extracted by the measurement device 4 are transmitted wirelessly (eg, BLE) to the data analysis/display device 70 (the external analysis device described above). The data analysis/display device 70 may be, for example, a smart phone or a tablet. 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 as well. The data analysis/display device 70 analyzes the received data and derives the heart rate and respiration rate. The data analysis and display device 70 may also derive other indices derivable from the beat interval, breath interval and body temperature data. Furthermore, the data analysis/display device 70 displays the derived heart rate and respiration rate, and transmits the heart rate, respiration rate, and body temperature data to the cloud server 80 . The cloud server 80 accumulates heart rate, respiration rate and body temperature data.

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

[Embodiment 2]
Other embodiments of the present disclosure are described below. For convenience of description, members having the same functions as those of the members described in the above embodiments are denoted by the same reference numerals, and description thereof will not be repeated. The same applies to subsequent embodiments. Note that the electrode structures 1B and 1C shown in FIGS. 5 and 6 may have a configuration in which the storage member 121 does not have the opening 121a like the electrode structure 1A which is a modification of the first embodiment. The same applies to the electrode structure 1D of Embodiment 3 (see FIG. 7) and the electrode structures 1E to 1H of Embodiment 4 (see FIGS. 8 to 11).

<Electrode structure 1B>
5001 and 5002 in 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 indicated by 5001 and 5002 in FIG. 5, the housing member 121 of the electrode structure 1B is formed with openings 125 that allow access to members housed inside the housing member 121 . In 5001 of FIG. 5, the above members are the water supply material 122, the waterproof material 123, and the elastic material 124. In FIG. In addition, the opening 125 is formed along the depth direction of the paper on the bottom of the storage material 121 (the side facing the mounting tool 2). Furthermore, the opening 125 has substantially the same length as the side of the storage material 121 extending along the direction. However, the opening 125 only needs to have a shape and size that allow access to the members stored 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 sides of the storage material 121 . Also, an opening 125 may be provided in a portion other than the bottom of the storage material 121 (eg, see FIG. 6).

Since the opening 125 is formed in the storage material 121, it is possible to replace the members inside the storage material 121. FIG. When the water supply material 122 is stored inside the storage material 121, for example, at the start of electrocardiographic measurement, a dropper or the like can be inserted into the opening 125 to supply water to the water supply material 122 without taking out the water supply material 122. can supply. Further, for example, at the start of electrocardiogram 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 members replaceable, when the water supply member 122, the waterproof member 123, or the expansion member 124 deteriorates, the deteriorated member can be replaced. In addition, when fungi such as mold are present in the water supply material 122, the waterproof material 123, or the stretchable material 124, it is possible to replace the member having the fungus. Therefore, continuous electrocardiogram measurement or a hygienic wearing tool 2 can be realized.

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

As described above, if the thickness of the electrode structure 1 is not adjusted appropriately, the electrodes 11 cannot be brought into close contact with the measurement site, interfere with electrocardiographic measurement, or damage the body surface. It may get lost. By forming the opening 125 in the storage material 121, the thickness of the electrode structure 1B can be easily changed by inserting and withdrawing the stretchable sheet each time the dog is fitted with the harness 2. FIG. Therefore, the occurrence of the above possibility can be reduced. That is, the electrode structure 1B can stably acquire a signal indicating an electrocardiogram without damaging the body surface of dogs having different hair conditions.

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

<Electrode structure 1C>
FIG. 6 is a cross-sectional view of the electrode structure 1C. As shown in FIG. 6, electrode structure 1C differs from electrode structure 1B in FIG. Since the opening 125 is formed in the side portion of the storage material 121, the user can access the members stored inside the storage material 121 without removing the electrode structure 1C from the mounting tool 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 part 12D differs from the electrode structure 1 in FIG. 1 in that it includes an elastic member 126 and a hollow member 127 instead of the elastic member 124 included in the electrode holding part 12 in FIG.

The stretchable material 126 can contain gas (eg, air) and expands and contracts according to the amount of the contained gas. The elastic member 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 allows gas to be inserted into or released from the elastic member 126 . The hollow member 127 is inserted into a through hole provided in each of the storage member 121 and the elastic member 126 . Hollow member 127 may be provided with a plug (not shown) for stopping the insertion or release of gas.

Thereby, the amount of gas contained in the elastic member 126 through the hollow member 127 can be changed. Specifically, by introducing gas into the elastic member 126 from the outside of the storage member 121 through the hollow member 127, the elastic member 126 can be thickened. On the other hand, the elastic member 126 can be thinned by discharging the gas from the inside of the elastic member 126 to the outside of the storage member 121 through the hollow member 127 . Since the thickness of the elastic member 126 can be changed 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 Embodiment 1 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 from above), the water supply material 122 is provided around the electrode 11. Also good. Examples of the configuration of such an electrode structure will be described below with reference to FIGS. 8 to 11, for example.

The electrode structures 1E to 1H shown in FIGS. 8 to 11 have openings 125 like the electrode structure 1B (see FIG. 5) and the electrode structure 1C (see FIG. 6) of the second embodiment. can be Moreover, the electrode structures 1E to 1H may be provided with a stretchable member 126 and a hollow member 127 like the electrode structure 1D (see FIG. 7) of the third embodiment. In addition, the electrode structures 1E to 1H may have a water supply material 122 and/or a waterproof material 123 inside the storage material 121 as well as 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 in FIG. 8 is a plan view of the electrode structure 1E, and 8002 in FIG. 8 is a cross-sectional view of the electrode structure 1E.

The electrode structure 1E includes an electrode 11 and an electrode holding portion 12E, as indicated by 8002 in FIG. The electrode holding portion 12E includes a storage material 121, a waterproof material 123, and an elastic material 124. As shown in FIG. The electrode holding part 12E is different from the electrode structure 1 of Embodiment 1 (see FIG. 1) in that it does not include the water supply material 122. As shown in FIG.

A waterproof material 123 is provided on the storage material 121 in the electrode holding portion 12E. That is, the storage material 121 has only the elastic material 124 inside. The storage material 121 and the waterproof material 123 are connected by being sewn with thread, for example. In this example, the waterproof material 123 is provided over the entire top of the storage material 121, but it may be of a size that can reduce the possibility that water from the water supply material 122 will be supplied to the storage material 121 side. .

Moreover, in the electrode structure 1E, as indicated by 8001 and 8002 in FIG. 8, the water supply material 122 is arranged on the electrode holding portion 12E over the entire periphery of the electrode 11 in plan view. Specifically, a layer containing the electrodes 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 directly contacts the measurement site or the surroundings of the measurement site. Even when the water supply material 122 is arranged in this manner, the water of the water supply material 122 can be supplied to the electrode 11 or the measurement site (that is, the contact portion thereof). The electrodes 11, the water supply material 122, and the waterproof material 123 are connected by, for example, sewing threads.

In this example, the water supply material 122 and the waterproof material 123 have the same shape when viewed from above, 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 moisture in the water supply material 122 is supplied to the wearing tool 2 side can be further reduced. The waterproof material 123 may have any size or shape as long as it can reduce the possibility that the moisture of the water supply material 122 is supplied to the storage material 121 side.

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 water in the water supply material 122 to be supplied to the electrode 11 or the measurement site when the dog is fitted with the harness 2 .

In addition, a through hole is provided in a 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, the electrode 11, the water supply material 122, and the waterproof material 123 are sandwiched between the electrode 11, the water supply material 122, and the waterproof material 123. When connecting, the through hole is not required. Further, in this case, a through-hole for taking out the conductor wire 3 from the inside of the housing member 121 is also unnecessary.

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

The electrode structure 1F includes an electrode 11 and an electrode holding portion 12F, as indicated by 9002 in FIG. The electrode holding part 12F has the same structure as the electrode holding part 12E shown in 8002 in FIG.

In the electrode structure 1E shown in FIG. 8, the water supply material 122 is arranged over the entire periphery of the electrode 11 when viewed in plan. may be provided with the water supply material 122. Even when the water supply material 122 is arranged in this way, the water 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 the approximate 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 of the sides and/or at least one of the corners of the electrode 11 . Also, a plurality of water supply materials 122 may be arranged for each side. Also, the water supply material 122 is provided so as to be separated from each side of the electrode 11, but may be provided so as to be in contact with them. 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 moisture of the water supply material 122 to the electrode 11 or the measurement site when the dog is fitted with the harness 2. Any positional relationship is acceptable.

Further, as indicated by 9002 in FIG. 9, the thickness of the water supply material 122 is thicker than the thickness of the electrode 11 . When the water supply material 122 is arranged partially around the electrode 11 in plan view, the water supply amount (water absorption amount) of the entire water supply material 122 is lower than when the water supply material 122 is arranged over the entire circumference. . As the thickness of the water supply material 122 increases, the amount of water supplied to the water supply material 122 can be increased. 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 make the dog disgusted. I wish I had.

Here, at 2002 in FIG. 2, the harness 2 is curved in the direction of line AA when worn on a dog. Therefore, when the water supply material 122 is provided along the line AA on the outside of the electrode 11 when viewed from above, the contact surface 122a is positioned so that the electrode 11 is arranged when the harness 2 is worn on the dog. You will face the direction you are. In other words, it becomes easier to supply water in the water supply material 122 to the electrode 11 or the measurement site side. From this point of view, the water supply material 122 may be provided along the line AA indicated by 2002 in FIG. 2 around the electrode 11 in plan view. In 9001 of FIG. 9, arrangement positions along line AA are indicated by symbols Po1 and Po2.

The electrode structure 1G includes an electrode 11 and an electrode holding portion 12G, as indicated by 10002 in FIG. The electrode holding portion 12G includes a storage member 121 and an elastic member 124. As shown in FIG. The electrode holding portion 12G differs from the electrode holding portion 12E of the electrode structure 1E and the electrode holding portion 12F of the electrode structure 1F in that it holds only the electrode 11 on its upper surface.

The electrode structure 1G, as indicated by 10001 and 10002 in FIG. 10, has water supply members 122 on both sides of the electrode 11 in plan view. In this example, the water supply material 122 has substantially the same thickness as the storage material 121 and is provided at a position adjacent to the storage material 121 .

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. This can reduce the possibility that the moisture in the water supply material 122 is supplied to the mounting tool 2 and the storage material 121 side. The waterproof material 123 is connected to the storage material 121 , but may be provided apart from the storage material 121 .

It should be noted that it is not always necessary to provide the waterproof material 123 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 side of the water supply material 122 opposite to the contact surface 122a (the surface side facing the mounting device 2) and one of the side surfaces of the water supply material 122 (surfaces other than the contact surface 122a and the opposite surface). It may be provided in the department. 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. In other words, it is sufficient that the waterproof material 123 is provided so as to reduce the possibility that the moisture retained in the water supply material 122 is supplied to areas 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) should be such that the moisture in the water supply material 122 can be supplied to the electrode 11 or the measurement site when the harness 2 is attached to the dog. Just do it. As for the thickness and size of one water supply material 122, the thickness and size of the water supply material 122 as a whole may be such that water can be supplied 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, similar to the bottom of the storage material 121 . In this case, the electrode structure 1G can be removed from the attachment 2. The storage material 121 and the waterproof material 123 may be connected by, for example, hook-and-loop fasteners so as to be separated from each other. In this case, the relative positional relationship between the electrodes 11 and the water supply material 122 can be easily changed. Further, the storage material 121 may be detachably connected to the wearing tool 2 and the waterproof material 123 , and the waterproof material 123 may be fixed to the wearing tool 2 at its connection position. When the opening 125 is formed in the storage material 121 as in the second embodiment, the user can easily insert or remove the stretchable material 124 by removing the storage material 121 from the wearing tool 2 .

In consideration of the shape of the harness 2 when worn on a dog, the water supply material 122 is provided along line AA indicated by 2002 in FIG. As a result, even with a structure in which the water supply material 122 is provided partially around the electrode 11 in plan view, it is possible to efficiently supply water to the electrode 11 or the measurement site.

However, if the above-described efficient water supply is not taken into consideration, the water supply material 122 does not necessarily need to be provided along the AA line. may be provided at a position along the Moreover, the water supply material 122 may be provided only on one side of the electrode 11 when viewed from above, or may be provided at four locations facing all sides of the electrode 11 .

The electrode structure 1H includes an electrode 11 and an electrode holding portion 12H, as indicated by 11002 in FIG. The electrode holding portion 12H has the same structure as the electrode holding portion 12G indicated by 10002 in FIG. 10, and has the electrode 11 on its upper surface.

As shown in 11001 and 11002 in FIG. 11, the electrode structure 1H has a water supply member 122 around the electrode 11 when viewed from above. The water supply material 122 is provided as a common water supply material for the two electrode structures 1H. Even in this case, the moisture 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.

A waterproof material 123 is provided at a position (immediately below the water supply material 122) facing the surface (opposite surface) of the water supply material 122 opposite to the contact surface 122a. This can reduce the possibility that the moisture in the water supply material 122 is supplied to the wearing tool 2 side.

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