近年、高齢者、入院患者、乳幼児などの要介護者の見守り、介護、看護の分野において、体調管理を遠隔操作型の生体情報計測機器にて行うことにより介護者の省力化ならびに診断などに応用する試みが成されている。
ここに生体情報とは体温、脈拍、呼吸数などに加え皮膚接触形電極を用いて測定される心電、筋電などの生体電位情報ならびに、皮膚インピーダンスの変化から読み取ることが出来る発汗状態などである。
これらのうち、特に皮膚接触形電極を用いる計測の場合には、電極の固定と、電気的接触状態の安定化のために電極と皮膚表面との間にゲル又はペーストの使用、あるいは粘着テープ等の使用が行われてきた。このため、長時間の連続計測においては発汗による不快感、掻痒感や違和感の発生を伴い、粘着テープ等の粘着性の高い貼り付け電極ではさらに皮膚炎を生じやすいという問題点があった。
In recent years, in the field of monitoring, care, and nursing of elderly people, hospitalized patients, infants, and other people in need of care, remote-controlled biological information measuring devices have been used to monitor physical condition, saving caregivers' labor and making diagnoses. Attempts have been made to do so.
Here, biological information includes body temperature, pulse rate, respiration rate, etc., as well as biopotential information such as electrocardiograms and myoelectric waves measured using skin-contact electrodes, and sweating status that can be read from changes in skin impedance. be.
Among these, in the case of measurements using skin-contact electrodes, it is necessary to use gel or paste between the electrode and the skin surface, or adhesive tape, etc., to fix the electrode and stabilize the electrical contact state. has been used. For this reason, long-term continuous measurement is accompanied by discomfort, itching, and discomfort due to sweating, and there is a problem that dermatitis is more likely to occur if the electrode is attached with a highly adhesive adhesive such as adhesive tape.
一方で、主にスポーツ分野などでは、衣服に電極と配線を取り付けて、運動中の生体情報を取得する試みが盛んに行われている（特許文献１）。特にスポーツ分野では、コンプレッション型ウェアと呼ばれる、身体にフィットしてやや締め付けるタイプのスポーツウェアが好まれているため、皮膚接触形電極の装着には好都合であった。
しかしながら、これらコンプレッションタイプの衣類は、高齢者の多い介護施設や、病院などでは、着用者が嫌うことに加えて、介護者による着用補助の手間が多大に必要となるため好まれない。介護施設や病院などでは、要介護者、患者らに、容易に着脱させることができる衣服型の生体情報計測装置が望まれている。
On the other hand, mainly in the sports field, attempts are being made to attach electrodes and wiring to clothing to obtain biological information during exercise (Patent Document 1). Particularly in the sports field, compression wear, which fits the body and is slightly tight, is preferred, which is convenient for wearing skin-contact electrodes.
However, these compression-type clothing are not preferred in nursing care facilities or hospitals where there are many elderly people, because not only the wearer dislikes them, but also the care worker requires a great deal of effort to assist them in putting them on. In nursing care facilities, hospitals, and the like, there is a demand for clothing-type biological information measuring devices that can be easily put on and taken off by care recipients and patients.
本発明は、かかる現状に鑑みてなされたものである。すなわち、本発明の目的は、衣類として着脱性に優れた生体情報計測装置を提供することにある。 The present invention has been made in view of the current situation. That is, an object of the present invention is to provide a biological information measuring device that is easy to put on and take off as clothing.

Furthermore, in the present invention, if the garment part is made without sewing, there will be no unevenness due to seams, so the wearer will feel less discomfort and bedsores will be less likely to occur.
以下本発明を図を用いて説明する。
図１は本発明における上半身用の生体情報計測装置の一例を示す概略図である。当該生体情報計測装置の衣服部は、上半身用の下着形状とすることが可能である。衣服部分は、図中の点線を境に、便宜上前身頃相当部分と後身頃相当部分を分かれているが、点線は縫い目では無く、全体は連続した切れ目や縫い目の無い一枚の不織布で構成されている。衣服を閉じるための、スナップファスナー、ホック、フック、ボタンなどは用いられていない。
The present invention will be explained below with reference to the drawings.
FIG. 1 is a schematic diagram showing an example of a biological information measuring device for the upper body according to the present invention. The clothing section of the biological information measuring device can be shaped like underwear for the upper body. For convenience, the garment part is divided into the front body part and the back body part by the dotted line in the figure, but the dotted line is not a seam, and the whole garment is made of a single piece of nonwoven fabric with no continuous cuts or seams. ing. No snap fasteners, hooks, hooks, or buttons are used to close the garment.
本発明の衣服部を構成する不織布は自着性のある不織布である。衣服部は、例えば、自着性のある不織布を平面裁断して得られる可展面である。
自着性のある不織布とは、生地自体には粘着性がないが、生地同士がくっつくテープである。自着性のある不織布は、具体的には、短繊維や仮撚倦縮加工糸等のかさ高い糸を用いて得られた織物や編物の起毛が、表面のランダムな毛羽により相手生地に張り付く現象（ファスナー現象）を利用したものである。
The nonwoven fabric constituting the clothing portion of the present invention is a self-adhesive nonwoven fabric. The clothing portion is, for example, a developable surface obtained by cutting a self-adhesive nonwoven fabric into a plane.
A self-adhesive nonwoven fabric is a tape that does not have adhesive properties itself, but the fabrics stick to each other. Non-woven fabrics with self-adhesive properties are those in which the raised fabrics or knits obtained using bulky yarns such as short fibers or false-twisted yarns stick to the other fabric due to the random fuzz on the surface. This utilizes a phenomenon (zipper phenomenon).
上記自着性のある不織布としては、例えば、綿やセルロース系繊維、ポリエステル、ナイロン、アクリル等の合成繊維からなる短繊維、ポリエステルやナイロンの仮撚倦縮加工糸、伸長性に優れたポリウレタン繊維などの組み合わせにより伸縮性と膨らみを持たせたストレッチ性の織物や編物に、ポリウレタン樹脂や合成ゴム素材、天然ゴム素材などの粘着性の弱い樹脂を加工し、自着性をもたせたものや、起毛加工によって自着性をもたせたものなどが挙げられる。起毛加工では、起毛面と非起毛面での自着性が高いため、表面同志、裏面同志では、自着性が低いが、表面と裏面の組み合わせでは、自着性が高い生地を製造できる。
また、二種類の生地を貼り合わせることによって、自着性を高めるとともに、裁断面からのほつれを防ぐこともできる。
Examples of the self-adhesive nonwoven fabrics include staple fibers made of cotton, cellulose fibers, synthetic fibers such as polyester, nylon, and acrylic, false-twisted and compressed yarns of polyester and nylon, and polyurethane fibers with excellent extensibility. Stretch fabrics and knitted fabrics that have elasticity and bulge are processed with low-adhesive resins such as polyurethane resin, synthetic rubber materials, and natural rubber materials to make them self-adhesive. Examples include those that have been given self-adhesive properties by being brushed. In the raising process, the self-adherence is high between the raised side and the non-raised side, so the self-adhesion is low between the front side and the back side, but it is possible to produce a fabric with high self-adhesion when the front side and the back side are combined.
Furthermore, by bonding two types of fabrics together, it is possible to improve self-adhesion and prevent fraying from the cut surface.
上記自着性のある不織布は、繊維径が１μｍ以下のナノ繊維を含む糸を用いて構成された織布または編布を用いることによって、容易に製造できる。上記ナノ繊維の繊維径とは、単繊維の直径を意味する。単繊維の断面形状が円形でない異形断面の場合は、単繊維の異形断面の外接円と内接円の直径の平均値を繊維径とする。ナノ繊維の繊維径は、好ましくは９００ｎｍ以下であり、より好ましくは８００ｎｍ以下である。ナノ繊維の繊維径の下限は特に限定されないが、ナノ繊維の製造容易性の点から、ナノ繊維の繊維径は１００ｎｍ以上が好ましく、２００ｎｍ以上がより好ましい。 The self-adhesive nonwoven fabric can be easily produced by using a woven or knitted fabric made of yarn containing nanofibers with a fiber diameter of 1 μm or less. The fiber diameter of the above-mentioned nanofibers means the diameter of a single fiber. If the single fiber has an irregular cross-section that is not circular, the fiber diameter is the average value of the diameters of the circumscribed circle and the inscribed circle of the irregular cross-section of the single fiber. The fiber diameter of the nanofibers is preferably 900 nm or less, more preferably 800 nm or less. Although the lower limit of the fiber diameter of the nanofibers is not particularly limited, from the viewpoint of ease of manufacturing the nanofibers, the fiber diameter of the nanofibers is preferably 100 nm or more, and more preferably 200 nm or more.
ナノ繊維の種類は特に限定されず、レーヨン等の再生繊維、アセテート等の半合成繊維、あるいは合成繊維等を用いることができる。ナノ繊維が合成繊維である場合、ナノ繊維の材質としては、ポリエチレンテレフタレート、ポリトリメチレンテレフタレート、ポリブチレンテレフタレート等のポリエステル類；ナイロン６、ナイロン６６等のポリアミド類等が挙げられる。ナノ繊維の断面形状は特に限定されず、円形、楕円形、多角形、星形等が挙げられる。
ナノ繊維は、複数束ねられて、織布または編布を構成する糸が形成されていることが好ましい。即ち、ナノ繊維はマルチフィラメント糸として織布または編布中に配されていることが好ましい。
The type of nanofiber is not particularly limited, and recycled fibers such as rayon, semi-synthetic fibers such as acetate, synthetic fibers, etc. can be used. When the nanofibers are synthetic fibers, examples of the material of the nanofibers include polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate; polyamides such as nylon 6 and nylon 66. The cross-sectional shape of the nanofibers is not particularly limited, and examples include circular, elliptical, polygonal, and star-shaped.
It is preferable that a plurality of nanofibers are bundled together to form a thread constituting a woven or knitted fabric. That is, the nanofibers are preferably arranged as multifilament yarns in a woven or knitted fabric.
ナノ繊維を含むマルチフィラメント糸の繊度は特に限定されないが、繊度は１０ｄｔｅｘ以上が好ましく、２０ｄｔｅｘ以上がより好ましく、５００ｄｔｅｘ以下が好ましく、３００ｄｔｅｘ以下がより好ましい。ナノ繊維を含むマルチフィラメント糸がこのような繊度を有していれば、マルチフィラメント糸が適度な強度を有するようになるとともに、マルチフィラメント糸から織布または編布を容易に形成できるようになる。
自着性のある不織布は、伸縮性を有していることが好ましい。また、自着性のある不織布は、通気性を有していることが好ましい。
The fineness of the multifilament yarn containing nanofibers is not particularly limited, but the fineness is preferably 10 dtex or more, more preferably 20 dtex or more, preferably 500 dtex or less, and more preferably 300 dtex or less. If the multifilament yarn containing nanofibers has such a fineness, the multifilament yarn will have appropriate strength and it will be possible to easily form woven or knitted fabrics from the multifilament yarn. .
It is preferable that the self-adhesive nonwoven fabric has elasticity. Moreover, it is preferable that the self-adhesive nonwoven fabric has air permeability.
次に、上記衣類に設ける生体接触電極について説明する。当該電極は、衣服部の着用者に接触する面に設けられる。当該電極は、例えば、ホットメルト型接着材によって衣服部の着用者に接触する面に接着されており、当該電極と、衣服部の生地との接着強度が、T字剥離法において７N／ｃｍ以上である。上記電極は、主として皮膚接触によって生体電位を検出するために用いられるが、コネクタ等の電気接点として用いても良く、その他の近接的非接触的なセンサーの検知端として用いてもよい。 Next, the biocontact electrode provided on the clothing will be explained. The electrode is provided on the surface of the garment that comes into contact with the wearer. The electrode is bonded to the surface of the clothing part that comes into contact with the wearer using, for example, a hot melt adhesive, and the adhesive strength between the electrode and the fabric of the clothing part is 7 N/cm or more using the T-peel method. It is. The above-mentioned electrode is mainly used to detect bioelectrical potential through skin contact, but it may also be used as an electrical contact for a connector or the like, or as a detection end of other close-contact non-contact sensors.
上記電極は、被測定者の運動動作に追従できるように伸縮性を有することが好ましい。
上記伸縮性を有する電極としては、例えば、導電性ファブリックで構成されている電極や、導電性フィラーと伸縮性を有する樹脂を含む導電性組成物から形成されたシート状の電極が挙げられる。
Preferably, the electrode has elasticity so that it can follow the movement of the subject.
Examples of the stretchable electrode include an electrode made of conductive fabric and a sheet-like electrode made of a conductive composition containing a conductive filler and a stretchable resin.
上記導電性ファブリックで構成されている電極としては、例えば、基材繊維に導電性高分子を被覆した導電性繊維または導電糸、あるいは銀、金、銅、ニッケルなどの導電性金属によって表面を被覆した繊維、導電性金属の微細線からなる導電糸、導電性金属の微細線と非導電性繊維とを混紡した導電糸などからなる織物、編物、不織布、あるいはこれら導電性の糸を非導電性の布帛に刺繍した物を導電性ファブリックからなる電極として用いることができる。 Electrodes made of the above-mentioned conductive fabric include, for example, conductive fibers or conductive threads in which base fibers are coated with conductive polymers, or surfaces coated with conductive metals such as silver, gold, copper, and nickel. woven fabrics, knitted fabrics, non-woven fabrics made of conductive fibers, conductive threads made of conductive metal fine wires, conductive yarns made of a blend of conductive metal fine wires and non-conductive fibers, or these conductive yarns are made of non-conductive fibers. Embroidered fabric can be used as an electrode made of conductive fabric.
上記導電性ファブリックは、身丈方向または身幅方向に１４．７Ｎの荷重をかけたときに、少なくとも一方の伸長率が３％以上６０％以下であることが好ましい。上記伸長率が下限値を下回ると、電極が衣類の生地の動きに充分に追従しにくくなり、生地から電極が剥がれることがある。従って上記伸長率は、３％以上が好ましく、より好ましくは５％以上、更に好ましくは１０％以上である。しかし、伸長率が上限値を超えると、電極が伸びすぎて生体情報を精度良く計測できないことがある。従って上記伸長率は、６０％以下が好ましく、より好ましくは５５％以下、更に好ましくは５０％以下である。
上記伸長率は、身丈方向または身幅方向で上記範囲を満足することが好ましく、身丈方向および身幅方向の両方において上記範囲を満足することがより好ましい。
When a load of 14.7 N is applied to the conductive fabric in the body length direction or the body width direction, it is preferable that at least one of the conductive fabrics has an elongation rate of 3% or more and 60% or less. If the elongation rate is below the lower limit, it becomes difficult for the electrode to sufficiently follow the movement of the fabric of clothing, and the electrode may peel off from the fabric. Therefore, the elongation rate is preferably 3% or more, more preferably 5% or more, still more preferably 10% or more. However, if the elongation rate exceeds the upper limit, the electrode may become too elongated, making it impossible to accurately measure biological information. Therefore, the elongation rate is preferably 60% or less, more preferably 55% or less, even more preferably 50% or less.
The elongation rate preferably satisfies the above range in the body length direction or the body width direction, and more preferably satisfies the above range in both the body length direction and the body width direction.
上記シート状の電極の材料としては、例えば、導電性が高い導電性フィラーを用いることによって、繊維状電極よりも電気抵抗値を低くすることができるため、微弱な電気信号を検知できる。 For example, by using a conductive filler with high conductivity as the material of the sheet-like electrode, the electric resistance value can be lowered than that of the fibrous electrode, so that weak electric signals can be detected.
上記電極は、生体に直接接触する電極表面以外の部分は絶縁カバーされることが好ましい。絶縁層は、生地側と肌側の双方に設けられることが好ましい。
また、本発明の装置は、電極の他、該電極と、該電極で取得した電気信号を演算する機能を有する電子ユニット等とを接続する配線ならびにコネクタが設けられる。
It is preferable that the electrode is covered with an insulating cover other than the electrode surface that directly contacts the living body. The insulating layer is preferably provided on both the fabric side and the skin side.
In addition to the electrodes, the device of the present invention is provided with wiring and connectors that connect the electrodes to an electronic unit or the like having a function of calculating electrical signals acquired by the electrodes.
本発明の装置は、例えば介護者によって、以下の様にして着用者に着用させることができる。
まず、介護者は、本装置をベッドの上などに広げ、次いで着用者を後身頃相当部分の上に寝かせる。次いで図２のように装置の（左）前身頃相当部分を着用者の胸および腹側に被せ、さらに図３に示すように（右）前身頃相当部分を重ねて、生地の自着性を使って身体の全面で衣服部を閉じる。さらに続いて図４に示すように肩部分を前面側に被せて、同様に生地の自着性を用いて接着する。図では左側のみを図示しているが、もちろん右側も同様に閉じることができる。また左右を入れ替えても問題は無い。
The device of the invention can be worn by a wearer, for example by a caregiver, in the following manner.
First, a caregiver spreads the device out on a bed or the like, and then places the wearer to lie on a portion corresponding to the back of the wearer's body. Next, as shown in Figure 2, the (left) front part of the device is placed over the wearer's chest and abdomen, and as shown in Figure 3, the (right) front part is overlapped to check the self-adhesion of the fabric. Use it to close the clothing part on the entire body. Further, as shown in FIG. 4, the shoulder portion is placed over the front side and adhered in the same manner using the self-adhesive properties of the fabric. Although only the left side is shown in the figure, the right side can of course be closed in the same way. There is no problem even if the left and right sides are swapped.
図５には下半身用の生体情報計測装置の一例を示す。当該生体情報計測装置の衣服部は、下半身用の下着形状とすることが可能であり、上半身用途同様、縫い目の無い一枚の平面から構成されており、スナップファスナー、ホック、フック、ボタンなどの係合部材は使われていない。図６に示すように、いわゆる「おむつ」を装着する手順で着用させることが出来るため、一般的なパンツ形状の下着に足を通す手間を省くことができる。 FIG. 5 shows an example of a biological information measuring device for the lower body. The clothing part of the biological information measuring device can be shaped like underwear for the lower body, and like the upper body, it is composed of a single seamless plane and has snap fasteners, hooks, hooks, buttons, etc. No engagement member is used. As shown in FIG. 6, the wearer can be put on the wearer by following the procedure of putting on a so-called "diaper", which eliminates the need to put one's feet through a typical pant-shaped underwear.
図７にはベルト形状の生体情報計測装置の一例を示す。ベルト形状の装置の場合には胸部、腹部、あるいは必要に応じて四肢などに簡単に装着させることができる。 FIG. 7 shows an example of a belt-shaped biological information measuring device. In the case of a belt-shaped device, it can be easily attached to the chest, abdomen, or limbs as needed.
以上述べてきたように、本発明の生体情報計測装置は、自着性のある不織布にて、好ましくは縫製加工を行うことなく作製した衣服に電極、配線などを取り付けて生体情報計測装置としており、自着性を利用して、被着用者を包むように着用させたのちに生地どうしを合わせることにより、寝た姿勢の要介護者の場合にも身体の上側で衣服を閉じることができる。
本発明の生体情報計測装置は、介護者により着用者に簡易に着用させることができ、衣服部分に縫製による凹凸が無いため、着用者の不快感が少なく、床ずれなども生じにくい。
また廉価な不織布を材料とするため、装置の衣服部分をディスポーザルとすることにより、さらなる省力化とともに、清潔性も得ることができ、介護施設、病院、リハビリテーション施設はもちろん、一般家庭においても有用に用いる事ができる。
As described above, the biological information measuring device of the present invention is made by attaching electrodes, wiring, etc. to clothing made of self-adhesive nonwoven fabric, preferably without sewing. By utilizing the self-adhesive properties of the garment and wrapping it around the wearer and then aligning the fabrics together, the garment can be closed on the upper side of the body even when the person in need of care is in a lying position.
The biological information measuring device of the present invention can be easily put on the wearer by a caregiver, and since there are no irregularities caused by sewing on the clothing portion, the wearer feels less discomfort and is less likely to cause bedsores.
In addition, since it is made of inexpensive non-woven fabric, the clothing part of the device can be made disposable, further saving labor and improving cleanliness, making it useful not only in nursing care facilities, hospitals, and rehabilitation facilities, but also in general households. It can be used for.
