Abstract

A mat for bedsore prevention, on which the pressure against portions such as sacrum liable to bedsore is kept below 30 mmHg/cm2, a critical value that causes bedsore if it lasts long. The mat comprises a bag-shaped body (1) having rectangular parallelepiped recesses in a central portion and both side thereof, and bag-shaped auxiliary supports (2) adapted to be fitted in the recesses. The auxiliary supports (2) are made several centimeters thinner than the body (1) to provide a difference in level. The body (1) is inflated with air, and the auxiliary supports (2) are filled with water to 60 % of its capacity. With the arrangement of the mat, a major part of the weight of a human body is applied on the body (1) but not much on auxiliary supports (2). Accordingly, sacrum, greater trochanter and ilium, which are liable to bedsore and supported by the sub-supports (2) receive lower pressure than other places supported by the body.

明 細 書 褥瘡予防ハイプリッド型エア一.ウォーターマツト 技術分野  Description Hydride type air for pressure ulcer prevention Water mat
本発明は、 仙骨部等、 褥瘡好発部位にかかる圧力を特に低減させるために開発 された褥瘡予防マツトに関するものである. 背景技術  The present invention relates to a pressure ulcer prevention mat developed specifically for reducing pressure on pressure ulcer-prone sites such as the sacrum.
従来の裤瘡予防マットは、 体重をマット全体に均等に分散させることで、 仙 骨部など褥瘡好発部位の単位面積にかかる圧力を小さくしょうとするもので あつ 7i«  Conventional acne prevention mats attempt to reduce the pressure applied to a unit area of a pressure ulcer-prone area, such as the sacrum, by distributing weight evenly throughout the mat.
しかし従来の褥瘡予防マツトの多くは， 体表面との有効接触面積があまり広 く取れないために、 その方法では褥瘡好発部位の単位面積にかかる圧力を低く するには限界があった。  However, many conventional mats for preventing pressure ulcers have a limited effective contact area with the body surface, so there is a limit in reducing the pressure applied to the unit area of a pressure ulcer-prone area by this method.
それ以外の方法で祷瘡好発部位の単位面積にかかる圧力を低くするには、 そ こにかかる圧力のみを下げることができれば問題ないが、 そのような機構を持 つマツ卜は存在しなかった.  To reduce the pressure applied to the unit area of acne-prone sites by other methods, there is no problem if only the applied pressure can be reduced, but no mat with such a mechanism exists. Was.
エアーマツトはある程度褥瘡予防に有効とされているが、 ①その形態上凹凸 面が多く、 体表面との有効接触面積があまリ広く取れない。 ②マットを膨らま せるために、 比較的高い圧力で空気を封入しなければならない。 等の理由によ リ体表面の単位面稷にかかる圧力を、 枏瘡発生臨界値である 30mmHg/crn2以下に 下げることは不可能であった. よって頻回の***交換をしなければ， こと仙骨 部に関してはやはリ褥瘡ができていた. さらにエアーマットは、 体重がかかつ たときエアーセルに復元力が発生し、 そのためにその郎の皮 に張力が働くた め、 それがさらに褥瘡形成を促進する結果になっていた。 Air mat is considered to be effective in preventing pressure ulcers to some extent, but (1) it has many irregularities due to its form, and the effective contact area with the body surface cannot be wide enough. ② In order to inflate the mat, air must be filled with relatively high pressure. The pressure applied to the unit surfaces millet by Li surface because of the equal, unless lowering the 30 mmHg / crn 2 or less is枏瘡generating critical value was impossible. Therefore the frequent repositioning, In the sacral area, pressure ulcers were formed. In addition, when the weight of the air mat was increased, the air cell had a restoring force, which caused tension on the skin of the dwarf, which further increased pressure ulcers. This resulted in promoting formation.
ウォーターマットは、 体表面との有効接 «面積が比較的広く取れ、 仙骨部な ど褥瘡好発部位の圧力が、 褥瘡発生臨界値である 30mmHg/cm2以下になるとい うことでは優れている. しかし①大量の水も使用するため非常に重くて扱いに くい， ②ウェーブ現象 (水の捆れ)のために寝にくい。 ③マット面が不安定のた め寝返リゃ***交換がしにくい. 等の欠点があった， 発明の開示 Water mat, taken relatively wide effective contact «area with the body surface, have a pressure of sacral soil decubitus predilection becomes below 30 mmHg / cm 2 is bedsores occur critical value However, it is very heavy and difficult to handle because a large amount of water is used, and it is difficult to sleep due to the wave phenomenon (water spill). (3) The mat surface is unstable, and it is difficult to change the body position.
本発明は、 このような従来技術の持つ欠点を解消するために案出されたもの である。 すなわち①体重がマット全体に均等に分散される， ②仙骨部など褥瘡 好発部位にかかる圧力が、 常時裤瘡発生臨界値である 30mmHg/cin2以下にな る. ③仙骨部など棵瘡好発都位の皮膚への張力があまり作用しない. ④軽く扱 いやすい。 ⑤寝にくいなどの違和感がなく使用できる. これらの条件を満たす マツトの闢発を目的とするものである. The present invention has been devised to solve such disadvantages of the prior art. That ① weight is evenly distributed throughout the mat, pressure applied to pressure ulcers predilection sites, etc. ② sacral part, 30 mmHg / cin 2 ing below is always裤瘡generating critical value. ③ sacral such棵瘡good The tension on the skin at the starting point does not act much. ④Light and easy to handle.で き る Can be used without discomfort such as difficulty in sleeping. It is intended to develop Matsuto that meets these conditions.
本体は空気で膨らまし、 副支持体は水を全容積の 60%程度入れて、 副支持体を 本体にはめ込む. そして仙骨郁が中央の副支持体に当たるようその上に寝て使 用する. 寝た瞬間はまず身体が本体にのみ支えられ、 仙骨都を支える副支持体 は本体より低いので、 仙骨部は宙に浮いた状態となっている。 次に体重が本体 にかかることによリ、 本体は演れ身体が少し沈むことによリ、 仙骨部が副支持 体に支えられる。 この時点で体重の大部分が本体にかかり、 副支持体にはあま リ体重がかからない， また副支持体に体重がかかっても、 容穣にかなりの余裕 があるため中の水が移動することにより、 副支持体の中の圧力はあまリ上がら ない. そこから側臥位になったときの大転子部 ·腸骨部と、 外側の副支持体との 関係も同様である， つまリ褥瘡好発部位である仙骨都及び大転子都 ·腸骨都にかか る圧力は、 本体に支えられているその他の部位に比べ低くなる.  The main body is inflated with air, and the sub-support is filled with about 60% of the total volume of water, and the sub-support is inserted into the main body. At the moment, the body is first supported only by the main body, and the sub-support that supports the sacral capital is lower than the main body, so the sacral part is in a state of being suspended in the air. Next, the weight is applied to the main body, the main body plays, and the body sinks a little, and the sacrum is supported by the sub-support. At this point, most of the weight is applied to the main body, and the sub-support is not weighed too much, and even if the sub-support is weighted, there is considerable room for fertilization and the water inside moves. Due to this, the pressure in the sub-support does not rise satisfactorily. The relationship between the greater trochanter and ilium and the outer sub-support when the patient is in the lateral position is also the same. The pressure on the sacral, trochanteric, and iliac cities, which are the most common sites, is lower than that of other parts supported by the main body.
また副支持体にあまり体重がかからない結果， 副支持体の復元力もあまリ発 生しないので、 仙骨部及び大転子部-腸毋郁の皮膚に張力がほとんど生じなレ、。 図面の簡単な説明  Also, as a result of the fact that the weight of the sub-support is not so large, the restoring force of the sub-support does not generate enough, so that almost no tension is generated on the skin of the sacrum and the greater trochanter-intestine.

BEST MODE FOR CARRYING OUT THE INVENTION
以下、 本発明の実施例を図面を参照しながら説明する。  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図 1のように、 中心部及びその両側に仙骨部ボケット (3)及び大転子部ポケット (4)のある本体 (1)と、 それらポケットにはめ込む副支持体 (2)を、 塩化ビニール やウレタン等で作成する， 中心部の仙骨部ポケット (3)の位置は、 仰臥位になつ たとき仙骨部が当たる位置で、 左右の大転子郁ポケット (4)の位置は、 その状態 から側臥位になったとき左右の大転子郁.腸母部が当たる位 に作る。 副支持体 (2)の厚さは本体 (1)より数 cm薄くし、 使用時本体 (1)の高さよリ副支持体 (2)が低く なるようにする， 本体ひ)の大きさは， 最低腰臂部を支持できる大きさ以上で， 副支持体 (2)は仙骨部及び大転子部 ·腸骨部周囲を支持できる大きさ、 20 X 20cm程 度にする。 本体 (1)の空気栓及び副支持体 (2)の水を入れる栓は、 それぞれの側面 の適当な位置に取りつける。 本体 (1)は空気で膨らませ、 副支持体 (2)には水を入 れる力 水は全容積の 60%程度 (約 If)にして容積に余裕を持たせ、 体重がかかつ たとき水が移動し内圧が上がらないようにする. また中の水が溷つたときには 水を交換するため、 副支持体 (2)は中が見えるように半透明にする. 副支持体 (2) を本体 (1)のそれぞれの位置にはめ込む.  As shown in Fig. 1, the main body (1), which has a sacral bocket (3) and a greater trochanter pocket (4) at the center and on both sides, and a secondary support (2) that fits into those pockets, The position of the central sacral pocket (3) made of urethane etc. is the position where the sacrum hits when in the supine position, and the position of the left and right trochanteric pockets (4) is the lateral position from that state When it comes to the position, Iku Otoriko is left and right. The thickness of the sub-support (2) should be several centimeters thinner than the main body (1), and the sub-support (2) should be lower than the height of the main body (1) in use. The secondary support (2) should be at least 20 X 20 cm, large enough to support the sacrum, the greater trochanter and the iliac area. The air taps on the body (1) and the water taps on the secondary support (2) shall be installed at appropriate positions on each side. The main body (1) is inflated with air, and the sub-support (2) is capable of entering water.The water is about 60% of the total volume (about If) so that there is room for the volume. The sub support (2) is made translucent so that the inside can be seen. In order to exchange the water when the water inside is mixed, the sub support (2) is the main body. Fit into each position of (1).
以上のような構成で、 図 2のように仰臥位のとき仙骨部ポケット (3)にはめ込 んだ副支持体 (2)が仙骨部に当たるように寝て使用する.  With the above configuration, when the patient is in the supine position as shown in Fig. 2, the sub-support (2) fitted in the sacral pocket (3) is used while lying down so that it hits the sacral part.
本発明は、 副支持体 (2)に水、 本体 (1)に空気を使用するが， 本体 (1)と副支持体 (2)は独立しているため、 互いの圧力に影響されず、 仙骨部及び大転子都 '腸骨郁 に関してはウォーターマツトとして作用し、 その他の部位に関してはエアー マットとして作用する， そして更に以下のような効果が生じる，  The present invention uses water for the sub-support (2) and air for the main body (1), but since the main body (1) and the sub-support (2) are independent, they are not affected by each other's pressure, The sacrum and the greater trochanter act as water mats for the iliac bones and act as air mats for the other areas, and have the following effects:
副支持体 (2)は本体 (1)とは完全に独立し、 かつ本体 (1)ょリ低いため、 寝た瞬間 は身体が本体ひ)のみで支持され、 仙骨部は宙に浮いた状態になっている， 次に 本体 (1)が体重によリ渙れ身体が少し沈んだところで、 仙骨部が副支持体 (2)に支 持されることになる. しかしこの時点で体重の大部分が本体 (1)にかかるため、 副支持体 (2)にはあまリ体重がかからない， その上副支持体 (2)に体重がかかって も、 副支持体 (2)には容積にまだかなりの余裕があるため、 水が周囲に移動する ことによリ副支持体 (2)の中の圧力はあまリ上がらない. よって仙骨部ボケット (3)の副支持体 (2)に支持されている仙骨部は、 本体 (1)に支持されている他の部位 に比べ、 あまリ圧力がかからない， このことは以下の試联例で示したが、 本発 明では仙骨部及び大転子部 ·腸骨部にかかる圧力は、 エアーマツトでは不可能で あった常時褥瘡発生臨界値である 30mmHg/cm2以下に保つということが可能で ある。 The sub-support (2) is completely independent of the main body (1), and is lower than the main body (1), so that the body is supported only by the main body at the moment of sleeping, and the sacrum is in the air. Next, the body (1) is lysed by the body weight and the body sinks a little, and the sacrum is supported by the secondary support (2). However, at this point, most of the weight is applied to the main body (1), so the secondary support (2) is not weighed over, and the secondary support (2) is also weighted. However, since the secondary support (2) still has a considerable capacity, the pressure inside the secondary support (2) does not rise due to the movement of water around. The sacrum supported by the sub-support (2) of the bocket (3) is less susceptible to pressure than other parts supported by the body (1). showed, pressure on the sacrum and trochanter portion-iliac section in this onset Ming, can that keep 30 mmHg / cm 2 or less is always pressure ulcer occurrence threshold it was not possible in Eamatsuto is there.
側臥位にすると、 もう一つの搏瘡好発郁位である大転子部 · 骨都がちょうど 大転子郁ポケット (4)の副支持体 (2)の上に乗るようになる。 この場合も仙骨都と 同様の効果が得られる，  In the lateral position, the greater trochanter / bone, which is another acne-prone position, just rides on the sub-support (2) of the greater trochanteric pocket (4). In this case, the same effect as that of the sacral city can be obtained.
副支持体 (2)にあまり体重がかからない結果、 副支持体 (2)の復元力も発生しな 、ので、 仙骨部及び大転子部 ·Β»骨部の皮 Λに張力がほとんど生じな 、，  As a result that the sub-support (2) does not receive much weight as a result, the restoring force of the sub-support (2) does not occur, so that almost no tension is generated in the sacrum and the greater trochanter. ,
しかし本発明の最大の特徴は， 従来の製品では不可能であった特定の部位にか かる圧力を自由に調節できるという点にある. つまリこの発明は、 副支持体 (2) にかかる圧力を中の水の量を増滅することによリ無段階に設定可能なため、 仙 骨部や大転子都にかかる圧力を、 一人一人の体格に合わせ調節可能である.  However, the greatest feature of the present invention is that the pressure applied to a specific part, which was impossible with conventional products, can be freely adjusted. The pressure applied to the sacrum and the greater trochanter can be adjusted according to each individual's physique, since the amount of water in the sacrum can be set steplessly.
また副支持体に水を使用するが、 マットの一部分でぁリ、 合計 3程度である ため、 ウォーターマットと比較してかなり軽量で、 ウエーブ現象も問題になら ない.  Water is used for the secondary support.However, since it is only part of the mat, which is about 3 in total, it is considerably lighter than a water mat, and the wave phenomenon is not a problem.
他の実施例として、 副支持体を分けず 1個に速結したマツ卜 (図 4)やそれを小型 化したマツト（図 5)、 更には背あて (77)の付いた車椅子マツト（図 6)を作成する， このように副支持体の数や形ゃ大きさは、 必要に応じて適宜変更する。  Other examples include mats that are quickly tied into one without splitting the sub-support (Fig. 4), miniaturized mats (Fig. 5), and wheelchair mats with backrests (77) (Fig. 4). 6). The number, shape, and size of the sub-supports are appropriately changed as necessary.
本発明は本体ひ、 10、 15、 17)と副支持体 (2、 20、 25、 27)が独立しているた め、 それぞれ別のクッション材を使用することが可能である， すなわち本体 (1、 10、 15、 17)に水やゲルを入れたり、 スポンジ状の物質、 ビース状の物 K, 化学繊維、 あるいはスプリングなどを使用したクッションにして、 副支持 体 (2、 20、 25、 27)はそのまま本発明の水を入れたマットや、 あるいはその逆 等、 用途に応じて色々作成可能である， In the present invention, since the main body (10, 15, 17) and the auxiliary support (2, 20, 25, 27) are independent, it is possible to use different cushioning materials, that is, the main body ( Add water or gel to (1, 10, 15, 17), make a cushion using sponge-like substance, bead-like substance K, chemical fiber, or spring, etc. The body (2, 20, 25, 27) can be prepared in various ways according to the use, such as the water-filled mat of the present invention or vice versa.
なおこの本体と副支持体の 係は、 仙骨部や大転子部以外の褥瘡好発部位やそ れ以外で特に滅圧を必要とする部位にも応用する。  The relationship between the main body and the sub-support is also applied to pressure ulcer-prone sites other than the sacrum and the greater trochanter, and to other sites requiring particularly decompression.
以上本発明は特定の具体例で示されかつ説明されたが、 これ以外に変形体も上 記記載の特許請求範囲内で可能であることに留意されたい。  While the invention has been shown and described with respect to particular embodiments, it should be noted that other modifications are possible within the scope of the appended claims.
<試験例>  <Test example>
従来の空気圧固定型 (常に一定の空気圧によってマットを膨らせるタイプ)のェ ァ一マットと本発明の第 1実施例のマットとの比較試験結果を示す.  The results of a comparative test between a conventional air pressure fixed type mat (a type in which the mat is constantly expanded by a constant air pressure) and the mat of the first embodiment of the present invention are shown.
方法は、 被験者を体重別のグループに分け、 仙骨部にかかる単位面積の圧力を 各グループそれぞれ 30名測定し、 平均値を比較した。  In the method, subjects were divided into groups according to body weight, and the pressure per unit area applied to the sacrum was measured by 30 persons in each group, and the average values were compared.
圧力計は TALLEY Group Ltd.,(ENGLAND)製体圧計 (Model SD 500 Digital Skin Pressure Evaluator)を使用した。  The pressure gauge used was a body pressure gauge (Model SD 500 Digital Skin Pressure Evaluator) manufactured by TALLEY Group Ltd., (ENGLAND).
ぐ結果 >  Results>
図 7のように本発明の仙骨部にかかる単位面積当たりの圧力平均値は、 裤瘡発 生臨界値である 30mmHg/cm2を大幅に下回る値を示した。 As shown in FIG. 7, the average pressure per unit area applied to the sacral portion of the present invention was a value that was significantly lower than the acne development critical value of 30 mmHg / cm 2 .
それに比較して、 エアーマツ卜の仙骨部にかかる単位面稹当たりの圧力平均 値は、 常に褥瘡発生臨界値以上であり， 本発明の平均値の 3倍程度の値を示し このように本発明は従来の空気圧固定型のエアーマットに比べ， 滅圧能力に 有意の差が認められた。  In contrast, the average pressure per unit area applied to the sacrum of the air mat is always higher than the critical value for pressure ulcer occurrence, and is about three times the average value of the present invention. A significant difference was found in the decompression capacity compared to the conventional air pressure fixed air mat.
