Description

本発明は、患者又は被介護者の身体に掛かる体圧を取り除くための動作を補助する除圧動作補助具に関する。 TECHNICAL FIELD The present invention relates to a pressure-reducing movement aid that assists in movement to remove body pressure from the body of a patient or cared-for person.

長期間に亘って寝たきり状態にある患者又は被介護者（以下、「患者等」と略称することがある）の身体には、褥瘡が生じることがある。褥瘡は、身体の一部が自重等によって長時間圧迫され、その部分の血流が阻害されることによって生じるものであり、体圧（患者等自身の体重による圧力）が集中しやすい腰、背中、後頭部、踵等の部位に発生することが多い。 BACKGROUND OF THE INVENTION Pressure ulcers may occur on the bodies of patients or care recipients (hereinafter sometimes referred to as "patients, etc.") who are bedridden for a long period of time. Bedsores occur when a part of the body is compressed for a long time by its own weight, which obstructs the blood flow to that part. Bedsores are caused by pressure ulcers on the lower back and back, where body pressure (pressure due to the patient's own weight) tends to be concentrated. , often occurring in areas such as the back of the head and heels.

褥瘡を予防するためには、体圧を身体の前記部位に集中させずに体全体に分散させること（体圧分散）、及び体を動かして前記部位に掛かっている体圧を取り除くこと（除圧動作）が重要となる。 In order to prevent pressure ulcers, it is important to distribute body pressure throughout the body (body pressure distribution) rather than concentrating it on the specific area of the body (body pressure distribution), and to move the body to remove body pressure from the area (elimination). (pressure action) is important.

そこで、従来より、褥瘡の発生を防ぐ目的で、ポリウレタン等から成る発泡体又はエアー等が充填されたクッション又はマットレス等の体圧分散寝具が用いられている。しかしながら、このような体圧分散寝具は、患者等の体が沈み込むことによって体の動きが阻害されるため、除圧動作が困難になるという問題がある。 Therefore, body pressure dispersion bedding such as a foam made of polyurethane or a cushion or a mattress filled with air or the like has conventionally been used for the purpose of preventing the occurrence of bedsores. However, such body pressure dispersion bedding has a problem in that the patient's body sinks and movement of the body is inhibited, making it difficult to perform pressure relief operations.

特開2013-158426号公報Japanese Patent Application Publication No. 2013-158426

そこで、患者等の姿勢を自動的に変化させることによって除圧動作を行わせる装置が提案されている。このような装置は、例えば、ポンプによって、複数に分割されたエアーマットレスの各部に空気を導入（又は前記各部から空気を排出）することによって、該エアーマットレスに横たわっている患者等の身体を左右に傾斜させるものとなっている（特許文献１を参照）。 Therefore, an apparatus has been proposed that performs a decompression operation by automatically changing the posture of a patient or the like. Such a device, for example, uses a pump to introduce air into each part of an air mattress that is divided into a plurality of parts (or to expel air from each part), thereby moving the body of a patient, etc. who is lying on the air mattress from side to side. (See Patent Document 1).

しかし、このような装置は、構造が複雑且つ大掛かりであるため、比較的高価であると共に、設置するのに広いスペースを必要とする。そのため、このような装置は、家庭又は病院等の介護現場又は看護現場に容易に導入できるものではなかった。 However, such a device has a complicated and large-scale structure, is relatively expensive, and requires a large space for installation. Therefore, such a device cannot be easily introduced into a home or a nursing care site such as a hospital.

以下、本発明を実施するための形態について図面を参照しつつ説明を行う。図１は、本実施形態に係る除圧動作補助具１０の平面図であり、図２は前記除圧動作補助具１０の断面図である。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a pressure-reducing operation aid 10 according to the present embodiment, and FIG. 2 is a cross-sectional view of the pressure-removing operation aid 10.

本実施形態に係る除圧動作補助具１０は、可撓性のシート材から成る偏平な袋体１１の内部に少量の潤滑剤１４が封入された構成となっている。袋体１１は、平面視で略矩形（具体的には、四隅が丸められた長方形又は正方形）の形状を有しており、その長さＬは25cm～45cm、幅Ｗは35cm～55cmとなっている。本実施形態に係る除圧動作補助具１０は、２枚のシート材１２、１３の三辺を熱融着又は接着等によって互いに接合し、内部に潤滑剤１４を充填した上で、残りの一辺を接合することによって製造される。以下、便宜上、前記２枚のシート材のうち、一方を第１シート材１２とよび、他方を第２シート材１３とよぶ。 The pressure relief operation aid 10 according to this embodiment has a structure in which a small amount of lubricant 14 is sealed inside a flat bag 11 made of a flexible sheet material. The bag 11 has a substantially rectangular shape (specifically, a rectangle or square with rounded corners) in a plan view, and its length L is 25 cm to 45 cm, and the width W is 35 cm to 55 cm. ing. The pressure relief operation aid 10 according to the present embodiment is constructed by joining three sides of two sheet materials 12 and 13 to each other by heat fusion or adhesion, filling the interior with a lubricant 14, and then manufactured by joining. Hereinafter, for convenience, one of the two sheet materials will be referred to as the first sheet material 12 and the other will be referred to as the second sheet material 13.

第１シート材１２及び第２シート材１３は、いずれも可撓性を有し、伸縮性がなく、且つ潤滑剤１４が浸み込まない素材（すなわち防水性の素材）で構成されている。このような素材としては、例えば、ポリエチレン（PE）、ポリエチレンテレフタレート（PET）、ビニール、又はナイロン等の合成樹脂から成るシートを用いることができ、特に、可撓性に優れた、ポリエチレン製のシート材を用いることが望ましい。また、このような合成樹脂によって表面をコーティングされた布帛等を用いることもできる。第１シート材１２及び第２シート材１３の厚みは、いずれも0.01mm～0.1mm（より望ましくは、0.03mm～0.08mm）とすることが望ましい。 The first sheet material 12 and the second sheet material 13 are both made of a material that is flexible, non-stretchable, and into which the lubricant 14 does not permeate (that is, a waterproof material). As such a material, for example, a sheet made of synthetic resin such as polyethylene (PE), polyethylene terephthalate (PET), vinyl, or nylon can be used, and in particular, a polyethylene sheet with excellent flexibility can be used. It is desirable to use wood. Further, a cloth or the like whose surface is coated with such a synthetic resin can also be used. The thickness of the first sheet material 12 and the second sheet material 13 is preferably 0.01 mm to 0.1 mm (more preferably 0.03 mm to 0.08 mm).

潤滑剤１４は、第１シート材１２と第２シート材１３との間の摩擦を軽減して、両者を互いに滑りやすくするものである。潤滑剤１４としては、引火性がなく、人体に無害なものを用いることが望ましく、例えば、合成水溶性ポリマー、天然水溶性ポリマー、若しくは多糖類に、水を添加して成る粘稠性の水溶液（ジェル状又はローション状のもの）、プロピレングリコール、又はグリセリン等を好適に用いることができる。なお、潤滑剤１４には、防腐剤等の添加物を含有させてもよい。 The lubricant 14 reduces the friction between the first sheet material 12 and the second sheet material 13, making them easier to slide against each other. As the lubricant 14, it is desirable to use something that is non-flammable and harmless to the human body, such as a viscous aqueous solution made by adding water to a synthetic water-soluble polymer, a natural water-soluble polymer, or a polysaccharide. (gel-like or lotion-like), propylene glycol, glycerin, etc. can be suitably used. Note that the lubricant 14 may contain additives such as preservatives.

前記天然水溶性ポリマーとしては、例えば、アルギン酸塩等を用いることができる。また、前記合成水溶性ポリマーとしては、例えば、ポリアクリル酸系ポリマー、ポリアクリルアミド、ポリメタクリルアミド、ポリエチレンオキサイド、ポリビニルアルコール、又はポリビニルピロリドン等が挙げられ、特に、人体への安全性が高く潤滑性に優れているポリアクリル酸系水溶性ポリマーを用いることが望ましい。前記ポリアクリル酸系水溶性ポリマーとしては、例えば、ポリアクリル酸、ポリメタクリル酸、若しくはそれらの共重合体、又はそれらのアンモニウム塩、ナトリウム塩、若しくはカリウム塩等を用いることができ、特に、医療用又はマッサージ用の潤滑剤等に広く配合されているポリアクリル酸ナトリウムを用いることが望ましい。 As the natural water-soluble polymer, for example, alginate or the like can be used. Examples of the synthetic water-soluble polymers include polyacrylic acid polymers, polyacrylamide, polymethacrylamide, polyethylene oxide, polyvinyl alcohol, and polyvinylpyrrolidone. It is desirable to use a water-soluble polyacrylic acid polymer that has excellent properties. As the polyacrylic acid-based water-soluble polymer, for example, polyacrylic acid, polymethacrylic acid, or copolymers thereof, or ammonium salts, sodium salts, or potassium salts thereof, etc. can be used. It is desirable to use sodium polyacrylate, which is widely blended into lubricants for use or massage.

除圧動作補助具１０は、厚みが大きいと患者等の身体が沈み込んで体の動きが妨げられるため、なるべく薄くすることが望ましい。具体的には、潤滑剤１４を袋体１１の内部全体に均等に行き渡らせた状態で、潤滑剤１４から成る層（潤滑剤層）の厚みが0.3mm～2.0mm（より望ましくは0.5mm～1.0mm）となるようにすることが望ましい。このような厚みを実現するため、潤滑剤１４の封入量は、袋体１１の厚さ方向（すなわち図１の紙面方向）から見た面積100cm2あたり、3mL～20mL（より望ましくは5mL～10mL）とすることが望ましい。 If the pressure relief operation aid 10 is too thick, the patient's body will sink in and movement of the body will be hindered, so it is desirable to make it as thin as possible. Specifically, with the lubricant 14 evenly distributed throughout the interior of the bag 11, the thickness of the layer made of the lubricant 14 (lubricant layer) is 0.3 mm to 2.0 mm (more preferably 0.5 mm to 0.5 mm). 1.0mm). In order to achieve such a thickness, the amount of lubricant 14 sealed is 3 mL to 20 mL (more preferably 5 mL to 10 mL) per 100 cm 2 of area viewed from the thickness direction of bag 11 (that is, the direction of the paper in FIG. 1). ) is desirable.

本実施形態に係る除圧動作補助具１０は、例えば、寝台１６（若しくは布団）に寝転んだ状態の患者等１５の体の下に敷いたり（図３）、椅子１７（若しくは車椅子）に座った状態の患者等１５の体の下に敷いたり（図４）して使用される。なお、図３では、除圧動作補助具１０を患者等１５の腰の下に敷いているが、その他の部位、例えば、頭部、背中、又は踵等の下に敷くようにしてもよい。 The decompression operation aid 10 according to the present embodiment can be placed, for example, under the body of a patient 15 lying on a bed 16 (or a futon) (FIG. 3), or when sitting on a chair 17 (or a wheelchair). It is used by placing it under the body of a patient 15 (Fig. 4). In FIG. 3, the decompression operation aid 10 is placed under the waist of the patient 15, but it may be placed under other parts, such as the head, back, or heels.

除圧動作を妨げる最大の要因は、患者等１５の身体と該身体が乗せられている面、すなわち寝台１６若しくは布団、又は椅子１７若しくは車椅子等（以下、「寝台１６等」とよぶ）の上面との間の摩擦である。本発明に係る除圧動作補助具１０を患者等１５の身体と寝台１６等との間に挟むと、身体に当接しているシート材（例えば、第１シート材１２）と、寝台１６等に当接しているシート材（例えば、第２シート材１３）とが潤滑剤１４の作用によって互いに滑ることにより、寝台１６等に対して、患者等１５の身体を容易に動かすことができるようになる。したがって、患者自らが、寝台１６等の上で体の位置をずらしたり、体を左右に傾けたりといった除圧動作を容易に行うことができるようになる。また、介助者が患者等１５の身体を動かして除圧動作を行わせる場合にも、該除圧動作を容易に行えるようになるため、介助者の負担を軽減することができる。 The biggest factor that hinders the decompression operation is the body of the patient 15 and the surface on which the body is placed, that is, the upper surface of the bed 16 or futon, or the chair 17 or wheelchair (hereinafter referred to as the "bed 16, etc."). It is the friction between When the pressure relief operation aid 10 according to the present invention is sandwiched between the body of the patient 15 and the bed 16, etc., the sheet material (for example, the first sheet material 12) that is in contact with the patient's body and the bed 16 etc. The abutting sheet material (for example, the second sheet material 13) slides against each other due to the action of the lubricant 14, so that the body of the patient, etc. 15 can be easily moved relative to the bed 16, etc. . Therefore, the patient can easily perform decompression operations such as shifting the position of the patient's body on the bed 16 or the like or tilting the patient's body from side to side. Further, even when a caregiver moves the body of the patient or the like to perform a pressure relief operation, the burden on the caregiver can be reduced because the pressure relief operation can be easily performed.

以上、本発明を実施するための形態について具体例を挙げて説明を行ったが、本発明に係る除圧動作補助具１０は上記実施形態に限定されるものではなく、本発明の趣旨の範囲で適宜変更が許容される。例えば、上述した除圧動作補助具１０の長さＬ及び幅Ｗの寸法も、あくまで一例であり、これに限定されるものではない。例えば、長さＬ方向の寸法をより大きくして、寝台１６又は布団等に寝転んだ患者等１５の上半身全体若しくは下半身全体、又は全身を、本発明に係る除圧動作補助具１０の上に載せられるようにしてもよい。 Although the embodiments of the present invention have been described above with reference to specific examples, the pressure relief operation aid 10 according to the present invention is not limited to the above embodiments, and is within the scope of the spirit of the present invention. Appropriate changes are permitted. For example, the length L and width W of the pressure relief operation aid 10 described above are just examples, and are not limited thereto. For example, the dimension in the length L direction may be made larger, and the entire upper body, the entire lower body, or the entire body of the patient, etc. 15 lying on the bed 16 or a futon, etc., is placed on the decompression movement aid 10 according to the present invention. It may be possible to do so.

また、上記実施形態では、除圧動作補助具１０の平面形状を略矩形としたが、本発明に係る除圧動作補助具１０の平面形状はこれに限定されるものではなく、例えば、図５に示すような円形若しくは図６に示すような楕円形、又は四角以外の多角形など、種々の形状のものとすることができる。 In addition, in the above embodiment, the planar shape of the pressure relief operation aid 10 is approximately rectangular, but the planar shape of the pressure relief operation aid 10 according to the present invention is not limited to this, and for example, as shown in FIG. It can be of various shapes, such as a circle as shown in FIG. 6, an ellipse as shown in FIG. 6, or a polygon other than a square.

また、患者等１５が体を動かした際に、除圧動作補助具１０自体が寝台１６等の上で移動してしまうのを防ぐため、除圧動作補助具１０は、その表面（少なくとも寝台１６等と当接する面）に滑り止めを備えたものとすることが望ましい。この場合、第２シート材１３（又は第１シート材１２及び第２シート材１３）の製造時に、該シート材の表面に凹凸等から成る滑り止め部を形成しておくほか、袋体１１とは別体に構成された滑り止めシートを、袋体１１の表面に両面テープ又は接着剤等で貼り付けるものとしてもよい。なお、前記滑り止めシートの貼り付けは、除圧動作補助具１０の製造時に行ってもよく、使用者が必要に応じて行うようにしてもよい。 In addition, in order to prevent the pressure relief movement aid 10 itself from moving on the bed 16 etc. when the patient 15 moves their body, the pressure relief movement support tool 10 is attached to the surface thereof (at least on the bed 16 etc.). It is preferable that the surface that comes into contact with other objects has anti-slip properties. In this case, when manufacturing the second sheet material 13 (or the first sheet material 12 and the second sheet material 13), in addition to forming an anti-slip portion made of unevenness on the surface of the sheet material, Alternatively, a separately constructed anti-slip sheet may be attached to the surface of the bag body 11 with double-sided tape or adhesive. Note that the anti-slip sheet may be attached at the time of manufacturing the pressure relief operation aid 10, or may be attached by the user as necessary.

更に、上記の例では、袋体１１を、２枚のシート材１２、１３の外周縁を互いに接合して成るものとしたが、これに限らず、例えば、１枚のシート材を二つ折りにし、その外周縁のうち折り目以外の領域を接合して成るものとしてもよい。 Furthermore, in the above example, the bag body 11 is formed by joining the outer peripheral edges of the two sheet materials 12 and 13 to each other, but the present invention is not limited to this, and for example, one sheet material may be folded in half. , it may be formed by joining a region of the outer periphery other than the fold line.

以下の2種類の除圧動作補助具を使用して、本発明に係る除圧動作補助具の効果を検証した。
実施例１：PET樹脂から成る42cm×35cmのジッパー付き袋に潤滑剤100mLを封入したもの。
実施例２：PET樹脂から成る50cm×35cmのジッパー付き袋に潤滑剤200mLを封入したもの。
実施例１、２の双方において、前記潤滑剤として、ポリアクリル酸ナトリウムを主成分とする市販の潤滑ローションを使用した。なお、潤滑剤を前記各ジッパー付き袋の内部全体に均等に行き渡らせた状態において、該潤滑剤から成る層（潤滑剤層）の厚みは、実施例１で0.68mm、実施例２で1.14mmである。 The following two types of pressure relief operation aids were used to verify the effects of the pressure relief operation aid according to the present invention.
Example 1: 100 mL of lubricant was sealed in a 42 cm x 35 cm zippered bag made of PET resin.
Example 2: 200 mL of lubricant was sealed in a 50 cm x 35 cm zippered bag made of PET resin.
In both Examples 1 and 2, a commercially available lubricating lotion containing sodium polyacrylate as a main ingredient was used as the lubricant. In addition, when the lubricant is evenly distributed throughout the interior of each zipper bag, the thickness of the layer made of the lubricant (lubricant layer) is 0.68 mm in Example 1 and 1.14 mm in Example 2. It is.

被験者は腰椎骨折により長期に亘って寝たきりの状態にある成人女性１名であり、仰臥姿勢で寝台に横たわっている前記被験者の腰の下に、実施例１又は実施例２に係る除圧動作補助具を敷いて検証を行った。 The subject was an adult female who had been bedridden for a long period of time due to a lumbar vertebrae fracture. I installed the equipment and tested it.

前記被験者は、自力で腰部を動かすことができず、頻繁に介助者による体位変換を希望していたが、実施例１の除圧動作補助具を敷いた後は、自力で腰部を左右にずらしたり傾けたりすることができるようになり、介助者による体位変換を希望する頻度が減少した。また、当該被験者からは、わずかに体をずらすだけでも圧迫による腰部の不快感がかなり解消されるとの証言が得られた。実施例２の除圧動作補助具を使用した場合も同様の効果が得られたが、被験者によると、実施例１のものの方が、実施例２のものよりも体が動かしやすいように感じたとのことであった。 The subject was unable to move his lower back on his own and frequently requested a caregiver to change his position, but after the pressure relief movement aid of Example 1 was placed, he was able to move his lower back from side to side on his own. The patient is now able to tilt the patient's body up and down, and the frequency of requests for a caregiver to change the patient's position has decreased. The test subject also testified that the discomfort in the lower back due to pressure was significantly alleviated by simply shifting the body slightly. A similar effect was obtained when using the decompression movement aid of Example 2, but according to the subjects, they felt that it was easier to move their bodies in Example 1 than in Example 2. It was about.
