Description

四肢動物用の衣類clothing for quadrupeds
　本発明は、四肢動物の衣類に関するものであり、詳細には、四肢動物の胴体周りに配置することにより四肢動物の生体情報を計測できる衣類に関する。 The present invention relates to clothing for tetrapods, and more particularly, to clothing that can measure biological information of tetrapods by being placed around the body of the tetrapods.
　近年、ヘルスモニタリング分野や医療分野、療育分野、リハビリテーション分野において、人間が着用することにより生体情報を計測できる衣類が注目されている。また、近年では、ペットや家畜として飼っている犬、猫、牛などの四肢動物の健康状態を把握するために、四肢動物の生体情報を計測したいというニーズがある。そこで本発明者らは、特許文献１において、身体接触型の電極、コネクタ、電極とコネクタを接続する電気配線を有する衣服本体と、前記コネクタに着脱可能な電子ユニットを少なくとも構成要素とする動物用の生体情報計測用衣服を提案した。また、本発明者らは、特許文献２において、牛の健康状態を把握するための牛用の生体情報計測衣類を提案した。 In recent years, clothing that can measure biological information when worn by humans has attracted attention in the fields of health monitoring, medicine, nursing, and rehabilitation. Moreover, in recent years, there is a need to measure biological information of four-limbed animals such as dogs, cats, and cows kept as pets or livestock in order to grasp the health condition of the four-limbed animals. Therefore, the present inventors disclosed in Patent Literature 1, a body contact type electrode, a connector, a clothing body having electrical wiring for connecting the electrode and the connector, and an electronic unit detachable to the connector. We proposed clothes for biometric information measurement. In addition, the inventors of the present invention have proposed, in Patent Document 2, biological information measurement clothing for cattle for grasping the health condition of the cattle.
国際公開第２０１９／０３５４２０号WO2019/035420 国際公開第２０２１／１５３３２９号WO2021/153329
　上記特許文献１、２において提案されている衣類を四肢動物の胴体周りに着用させて四肢動物の生体情報を測定する際には、衣類の肌側の面に形成されている電極と四肢動物の身体とを密着させると共に、衣類が四肢動物の身体からズレないように、四肢動物の胴回り方向に衣類を締付ける必要がある。 When the clothing proposed in Patent Documents 1 and 2 is worn around the body of a tetrapod and the biological information of the tetrapod is measured, the electrodes formed on the skin side of the clothing and the electrodes of the tetrapod are used. The garment must be tightened around the quadruped's girth to provide a close contact with the body and to prevent the garment from slipping from the quadruped's body.
　ところで、四肢動物は、体表面に虫などの異物が付着したり、ストレスを感じたり、寒さを感じたときなど、身体を震わせることがある。四肢動物が身体を震わせると、四肢動物の身体は胴体周りの方向に大きく動く。そのため、四肢動物に着用させた衣類の胴回り方向への締付けをきつくしても、四肢動物が身体を震わせると、四肢動物の肌に接触していた電極が、所定の位置からズレてしまい、生体情報の測定精度が低下することがあった。また、四肢動物が横臥すると、四肢動物に着用させた衣類に四肢動物の胴回り方向への力が加わり、四肢動物の肌に接触していた電極が所定の位置からズレてしまい、生体情報の測定精度が低下することがあった。また、衣類を着用している四肢動物に、例えば他の四肢動物等が接触すると、四肢動物が着用している衣類に対し、四肢動物の胴回り方向へ力が加わることがあった。この場合にも四肢動物の肌に接触していた電極が所定の位置からズレてしまい、生体情報の測定精度が低下することがあった。 By the way, tetrapods may tremble when foreign objects such as insects adhere to their body surface, when they feel stress, or when they feel cold. When a tetrapod shakes its body, the tetrapod's body moves greatly in the direction around the trunk. Therefore, even if the clothing worn by the quadruped is tightly tightened in the direction of the waist, when the animal shakes its body, the electrodes that are in contact with the skin of the quadruped are displaced from the predetermined position. In some cases, the measurement accuracy of information decreased. In addition, when a tetrapod lies down, the clothes worn by the tetrapod are subjected to force in the direction of the girth of the tetrapod, causing the electrodes in contact with the tetrapod's skin to move out of position, resulting in the measurement of biological information. Accuracy was sometimes degraded. In addition, when a quadruped animal wearing clothes comes into contact with another quadruped animal, for example, a force is applied to the clothes worn by the quadruped animal in the direction around the waist of the quadruped animal. In this case as well, the electrodes that have been in contact with the skin of the quadruped are displaced from their predetermined positions, resulting in a decrease in the accuracy of measurement of biological information.
　本発明は上記の様な事情に着目してなされたものであって、その目的は、四肢動物に着用させた衣類に対し、四肢動物の胴回り方向に力が加わった場合でも四肢動物の生体情報を精度良く計測できる四肢動物用の衣類を提供することにある。 The present invention has been made in view of the above-mentioned circumstances, and its object is to obtain biological information of the tetrapod even when a force is applied to the clothing worn by the tetrapod in the direction of the girth of the tetrapod. To provide a clothing for a quadruped animal capable of measuring with high accuracy.

　本発明の四肢動物用の衣類によれば、四肢動物が着用している衣類に対し、四肢動物の胴回り方向に力が加わった場合でも四肢動物の生体情報を精度良く計測できる。 According to the clothing for quadrupeds of the present invention, the biological information of the quadruped can be accurately measured even when force is applied to the clothing worn by the quadruped in the direction of the girth of the quadruped.
　本発明の実施形態に係る衣類は、四肢動物の胴体周りに配置される衣類であって、四肢動物の胴体周りに配置される帯状本体部と、該帯状本体部の肌側の面に形成された電極とを有している。そして、前記帯状本体部は、少なくとも前記電極が形成されている領域において該帯状本体部１ｃｍ２当たりに対して該帯状本体部の厚み方向に５ｋｇの荷重をかけたときに、厚みが１０ｍｍ以上小さくなるものである。これにより、電極の位置がズレ難くなるため、生体情報の測定精度が向上する。即ち、帯状本体部の素材としてある程度の厚みがあり、しかも荷重に応じて変形しやすいものを選択することにより、四肢動物が着用している衣類に対し、四肢動物の胴回り方向に力が加わっても帯状本体部が身体の動きに追随して変形し、帯状本体部が緩衝材として作用する。そのため、帯状本体部の肌側の面に形成された電極は、四肢動物の肌に密着した状態を維持でき、生体情報を計測できる。なお、肌側の面とは、四肢動物の胴体周りに衣類を配置したときに、四肢動物の肌に接触する側の面を指す。 A garment according to an embodiment of the present invention is a garment to be placed around the body of a quadruped, comprising a strip-shaped main body arranged around the torso of the quadruped and a skin-side surface of the strip-shaped main body. and electrodes. The belt-shaped main body has a thickness that is reduced by 10 mm or more when a load of 5 kg per 1 cm 2 of the belt-shaped main body is applied in the thickness direction of the belt-shaped main body at least in the region where the electrodes are formed. It will be. This makes it difficult for the electrodes to be misaligned, thereby improving the measurement accuracy of biological information. That is, by selecting a material for the band-shaped main body that has a certain thickness and is easily deformed according to the load, force is applied to the clothing worn by the quadruped in the direction of the waist of the quadruped. The belt-shaped main body part deforms following the movement of the body, and the belt-shaped main body part acts as a cushioning material. Therefore, the electrodes formed on the skin-side surface of the band-shaped main body can maintain a state of being in close contact with the skin of the quadruped and can measure biological information. The skin-side surface refers to the surface that comes into contact with the skin of the tetrapod when the clothing is placed around the body of the tetrapod.
　帯状本体部１ｃｍ２当たりに対して該帯状本体部の厚み方向に５ｋｇの荷重をかけたときの厚みは、１５ｍｍ以上小さくなることが好ましく、より好ましくは２０ｍｍ以上である。帯状本体部の厚み方向に５ｋｇの荷重をかけたときの厚みは、できるだけ小さくなることが好ましい。帯状本体部の厚み方向に５ｋｇの荷重をかけたときに小さくなる厚みの上限は、荷重をかける前における帯状本体部の厚みによるが、例えば、４５ｍｍ以下が好ましい。 When a load of 5 kg is applied in the direction of the thickness of the belt-like body per 1 cm 2 of the belt-like body, the thickness is preferably 15 mm or more, more preferably 20 mm or more. It is preferable that the thickness of the belt-like main body when a load of 5 kg is applied in the thickness direction is as small as possible. The upper limit of the thickness of the belt-shaped main body that is reduced when a load of 5 kg is applied in the thickness direction depends on the thickness of the belt-shaped main body before the load is applied, but is preferably 45 mm or less, for example.
　本発明の実施形態に係る衣類は、少なくとも電極が形成されている領域に配される帯状本体部の厚みが、上記の範囲を満足していればよく、電極が形成されていない領域における帯状本体部の厚みは特に限定されないが、電極が形成されている領域を含む帯状本体部全体の厚みが、上記の範囲を満足していてもよい。 In the clothing according to the embodiment of the present invention, it is sufficient that the thickness of the belt-shaped main body portion arranged at least in the area where the electrodes are formed satisfies the above range, and the thickness of the belt-shaped main body in the area where the electrodes are not formed is sufficient. The thickness of the portion is not particularly limited, but the overall thickness of the strip-shaped body portion including the regions where the electrodes are formed may satisfy the above range.
　帯状本体部は、少なくとも電極が形成されている領域において該帯状本体部１ｃｍ２当たりに対して該帯状本体部の厚み方向に５ｋｇの荷重をかけたときに、非荷重時の厚みに対して５０％以上圧縮されるものが好ましい。非荷重時の厚みに対して圧縮される割合は、６０％以上がより好ましく、更に好ましくは７０％以上であり、特に好ましくは８０％以上である。非荷重時の厚みに対して圧縮される割合の上限は特に限定されず、１００％未満であればよく、９８％以下がより好ましく、更に好ましくは９５％以下、特に好ましくは９０％以下である。 When a load of 5 kg per 1 cm 2 of the belt-shaped main body is applied in the thickness direction of the belt-shaped main body at least in the area where the electrodes are formed, the thickness of the belt-shaped main body when no load is applied is 50%. % or more is preferable.

The upper limit of the ratio of compression to the thickness under no load is not particularly limited, and may be less than 100%, more preferably 98% or less, still more preferably 95% or less, and particularly preferably 90% or less. .
　本発明の実施形態に係る衣類は、少なくとも電極が形成されている領域に配される帯状本体部の圧縮割合が、上記の範囲を満足していればよく、電極が形成されていない領域における帯状本体部の圧縮割合は特に限定されないが、電極が形成されている領域を含む帯状本体部全体の圧縮割合が、上記の範囲を満足していてもよい。 In the clothing according to the embodiment of the present invention, it is sufficient that the compression rate of the belt-shaped main body disposed at least in the area where the electrodes are formed satisfies the above range, and the belt-shaped body in the area where the electrodes are not formed is sufficient. The compression rate of the main body is not particularly limited, but the compression rate of the entire strip-shaped main body including the region where the electrodes are formed may satisfy the above range.
　帯状本体部の素材は特に限定されないが、例えば、発泡体や網状構造体を含むことが好ましく、発泡体を含むことがより好ましく、発泡体のみで構成されることも好ましい。発泡体や網状構造体を用いることにより帯状本体部を厚くしても軽量化できるため、四肢動物に衣類を着用させたときの負担を軽減できる。また、発泡体を用いることにより保温効果を高めることもできる。 The material of the belt-shaped main body is not particularly limited, but for example, it preferably contains a foam or a network structure, more preferably contains a foam, and is also preferably composed only of a foam. By using a foam or a net-like structure, it is possible to reduce the weight of the band-shaped main body even if it is thick, so that the burden of wearing the clothes on the four-legged animal can be reduced. Moreover, the heat retention effect can be enhanced by using a foam.
　発泡体を形成する材料としては、例えば、ポリウレタン、ポリスチレン、ポリオレフィン（例えば、ポリエチレン、ポリプロピレンなど）、フェノール樹脂、ポリ塩化ビニル、ユリア樹脂、シリコーン、ポリイミド、メラミン樹脂などが挙げられる。これらのなかでもポリウレタンが好ましい。 Materials for forming foams include, for example, polyurethane, polystyrene, polyolefin (eg, polyethylene, polypropylene, etc.), phenol resin, polyvinyl chloride, urea resin, silicone, polyimide, and melamine resin. Among these, polyurethane is preferred.
　発泡体の形態は、シート状でもよいが、例えば、メッシュ状でもよい。これにより、通気性を高められるため、夏場でも快適に着用できる。 The form of the foam may be sheet-like, but may also be, for example, mesh-like. As a result, breathability is enhanced, making it comfortable to wear even in the summer.
　網状構造体とは、熱可塑性樹脂からなる線状体が、該線状体の交点で融着して網状を形成している構造を有する。 A network structure has a structure in which linear bodies made of a thermoplastic resin are fused at their intersections to form a network.
　熱可塑性樹脂としては、例えば、ポリオレフィン系熱可塑性樹脂、ポリエステル系熱可塑性樹脂、エチレン酢酸ビニル共重合体、ポリスチレン系熱可塑性樹脂、ポリウレタン系熱可塑性樹脂、ポリアミド系熱可塑性樹脂などが挙げられる。中でも、柔軟性に優れることから前記熱可塑性樹脂は、ポリオレフィン系熱可塑性樹脂、ポリエステル系熱可塑性樹脂またはエチレン酢酸ビニル共重合体が好ましく、より好ましくはポリオレフィン系熱可塑性樹脂である。これらの熱可塑性樹脂は、１種のみを使用してもよいし、２種以上を組み合わせて使用してもよい。 Examples of thermoplastic resins include polyolefin-based thermoplastic resins, polyester-based thermoplastic resins, ethylene-vinyl acetate copolymers, polystyrene-based thermoplastic resins, polyurethane-based thermoplastic resins, and polyamide-based thermoplastic resins. Among them, the thermoplastic resin is preferably a polyolefin-based thermoplastic resin, a polyester-based thermoplastic resin or an ethylene-vinyl acetate copolymer, and more preferably a polyolefin-based thermoplastic resin, because of its excellent flexibility. These thermoplastic resins may be used alone or in combination of two or more.
　線状体の形状は特に限定されず、線状体の内部は中実または中空のいずれであってもよく、線状体の断面形状は円形または異形のいずれであってもよい。 The shape of the linear body is not particularly limited, the interior of the linear body may be either solid or hollow, and the cross-sectional shape of the linear body may be circular or irregular.
　線状体の繊維径は、例えば、０．２０ｍｍ以上が好ましく、より好ましくは０．２２ｍｍ以上、更に好ましくは０．２４ｍｍ以上であり、１．０ｍｍ以下が好ましく、より好ましくは０．５０ｍｍ以下、更に好ましくは０．３５ｍｍ以下である。 The fiber diameter of the linear body is, for example, preferably 0.20 mm or more, more preferably 0.22 mm or more, still more preferably 0.24 mm or more, and preferably 1.0 mm or less, more preferably 0.50 mm or less. More preferably, it is 0.35 mm or less.
　網状構造体としては、例えば、東洋紡社製「ブレスエアー（登録商標）」、呉羽テック社製「クレバルカー（登録商標）」、旭化成社製「フュージョン（登録商標）」等の市販品や、これらの圧縮体が好ましく用いられる。 As the network structure, for example, commercially available products such as "Breath Air (registered trademark)" manufactured by Toyobo Co., Ltd., "Krevalker (registered trademark)" manufactured by Kureha Tech Co., Ltd., and "Fusion (registered trademark)" manufactured by Asahi Kasei Corporation, and these Compressed bodies are preferably used.
　帯状本体部の厚みは１０ｍｍを超えていれば特に限定されないが、例えば、１１ｍｍ～５０ｍｍが好ましい。帯状本体部の厚みが１１ｍｍ以上であることにより、四肢動物の動きが吸収されやすくなるため、電極がズレにくくなり、生体情報の測定精度が向上する。帯状本体部の厚みは、１５ｍｍ以上がより好ましく、更に好ましくは２０ｍｍ以上である。しかし、帯状本体部が厚くなり過ぎると重くなるため、四肢動物への負担が大きくなる。従って帯状本体部の厚みは、５０ｍｍ以下が好ましい。帯状本体部の厚みは、４５ｍｍ以下がより好ましく、更に好ましくは４０ｍｍ以下である。 The thickness of the belt-shaped main body is not particularly limited as long as it exceeds 10 mm, but is preferably 11 mm to 50 mm, for example. When the thickness of the band-shaped main body is 11 mm or more, the movement of the four-legged animal is easily absorbed, so that the electrodes are less likely to be displaced, and the measurement accuracy of biological information is improved. The thickness of the belt-like main body is more preferably 15 mm or more, and still more preferably 20 mm or more.

When a tetrapod moves its body by trembling or lays down, a force acts in the direction of the waist of the tetrapod, and the clothes worn by the tetrapod also receive a force in the direction of the waist of the tetrapod. Even in this case, the base fabric moves while maintaining contact with the body of the tetrapod, but the movement of the body of the tetrapod is less likely to be transmitted to the belt-like body portion arranged on the base fabric. , the band-shaped main body portion is less likely to shift from a predetermined position around the waist of the quadruped. In addition, when a quadruped animal wearing the clothing of the present invention comes into contact with, for example, another quadruped animal and a force is applied in the direction of the girth of the quadruped animal, the clothing worn by the quadruped animal may Also, force is applied in the girth direction of the tetrapod. In this case, the strip-shaped main body placed on the base fabric moves in response to an external force, but the base fabric maintains contact with the body of the tetrapod, so the electrodes placed on the base fabric are It becomes difficult to shift from a predetermined position around the girth of the quadruped animal. As a result, the measurement accuracy of biological information is further improved.
