Description

【０００１】
【発明の属する技術分野】
本発明は、寝たきりの人の床ずれを防止するために人とベッドの間に配設して身体と下側の支持部分との長時間にわたる密着を防ぐ床ずれ防止マットに関する。
【０００２】
【従来の技術】
寝たきりになった人の床ずれを防ぐために、身体背中側の各部分に対し所定時間間隔で接触箇所を変えつつ所定の圧力で部分的に接し、身体を支える床ずれ防止マットは、様々な形状や方式のものが従来から用いられている。
こうした従来の床ずれ防止マットのうち、マット上に仰向けで寝た状態の人に対しマット縦方向に空気圧による膨張・収縮部を複数配設し、複数箇所での膨張、収縮により支持位置を変化させつつ身体を支持するエアマットタイプのものは、身体をバランス良く支持できると共に、構造が簡略で取扱いやすく、従来から広く用いられてきた。このようなエアマットタイプの床ずれ防止マットの一例を図１３に示す。図１３は従来の床ずれ防止マットの斜視図である。
【０００３】
前図に示す従来の床ずれ防止マット１００は、略シート状のベースマット１０１と、細長い中空体で形成され、ベースマット１０１上に複数並列させて一体に取付けられて空気の注入、排出で膨張・収縮する複数の空気セル１０２と、空気セル１０２を覆うように配設される防汚シート１０３と、各空気セル１０２に対し管１０４を介して空気の加圧注入もしくは吸引排出を行う空気注入排出装置（図示を省略）とを備える構成である。
【０００４】
この従来の床ずれ防止マット１００では、人が防汚シート１０３上に仰向けに寝ている状態で空気注入排出装置が作動すると、各空気セル１０２に対する空気の注入、排出が適宜切換わって空気セル１０２の膨張・収縮状態が調整され、膨張時には身体に対する所定の支持力を発生させると共に収縮時には支持状態を解除して、人の肩から背中、さらに腰から脚にかけて多数の接触位置で接しつつ接触位置が所定のタイミングで入れ替って常時密着した状態を防ぎ、床ずれを防止することができる。
【０００５】
【発明が解決しようとする課題】
従来の床ずれ防止マットは以上のように構成されていたことから、防汚シート１０３が空気セル１０２を完全に覆っている状態では、空気セル１０２が汚れることはないものの、図１４に示すように、防汚シート１０３上の人の動きで防汚シート１０３がずれ、空気セル１０２が露出することがあった。この防汚シート１０３がずれて空気セル１０２を覆わない状態で寝ている人に失禁等があった場合、汚物が空気セル１０２間に入り込んでしまうという課題を有していた。
【０００６】
この空気セル１０２間に入り込んだ汚物を除去する場合、空気セル１０２が膨張したままでは空気セル１０２間に手が入らずに除去作業ができないため、通常は空気セルから空気を抜いていたが、空気セルが収縮してつぶれた状態になっても、空気セルを一枚ずつめくりながらの作業では汚れを落しにくかった。一方、ベースマット１０１から一旦空気セル１０２を取外して洗浄を行うと、確実に汚れを落せるものの、取外しには手間がかかる上、洗浄時に管１０４との接続用開口部から空気セル１０２内に水が入りやすく、水が入った場合、使用時に空気を送る管１０４の詰りや、空気セル１０２内の異音、空気セル１０２内からの空気排出時に異臭等が生じるといった課題を有していた。
【０００７】
また、従来の床ずれマットは、並列して隣合う空気セル１０２を交互に膨張、収縮させることで支持位置を変化させ、床ずれを防ぐ仕組みであるが、波打ち状の体圧支持となることから、マット上に寝ている人の皮膚を引張り、ずれや摩擦を引き起す危険があるという課題を有していた。また、膨張した空気セル１０２が身体に対し横方向に連続して接触するため、縦方向の血流を圧迫により分断する状態となり、身体の縦方向の血行が悪くなり、体調に悪影響を及すという課題を有していた。
【０００８】
本発明は前記課題を解消するためになされたもので、空気セルをマット横方向に複数配設し、メンテナンスを容易にすると共に、マットにおける身体の支持位置を適切に配置でき、床ずれ防止に留まらず寝ている人を所定の姿勢に調整できる床ずれ防止マットを提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明に係る床ずれ防止マットは、寝た姿勢の人の全身を載置可能な大きさに形成されるシート体と、当該シート体上面側に重ねて配設される可撓性を有するカバー体と、前記シート体及びカバー体との間に複数並列させて配設される中空の空気セルと、当該空気セルの中空部分に連通する連通路を介して空気セルに接続される空気注入排出手段とを備え、当該空気注入排出手段が、各空気セルに対し連通路を通じた空気の注入、排出を、注入対象と排出対象を切替えつつ繰返し行い、空気セルを膨張、収縮させる、床ずれ防止マットにおいて、前記空気セルが、複数の独立した略立方体状の小型中空体を直列に連結して形成されると共に、前記小型中空体同士を連通させ且つ通過する空気に対し通過抵抗を与える絞り通路を各小型中空体の連結部分にそれぞれ形成され、小型中空体同士が絞り通路のある前記連結部分を除いて間隔を空けて配置されてなり、また、前記空気セルが、前記シート体とカバー体との間で隣合って並ぶ二つについては連通路を別系統とされつつ、複数の空気セルについて連通路をそれぞれ合流させて二系統にまとめられて前記空気注入排出手段と接続され、複数の空気セルが同時に膨張、収縮を行う状態とされ、前記空気注入排出手段が、隣合う空気セルにそれぞれ連通する別系統の連通路に対して空気の注入もしくは排出の動作状態を異ならせるものである。
このように本発明においては、空気を中空部分に出入りさせられる複数の空気セルが、シート体とカバー体との間に複数並列させて配設され、空気注入排出手段を作動させて各空気セル毎に膨張、収縮を所定時間間隔で繰返させ、カバー体上の人の身体各部分への接触位置を所定時間間隔で次々に変えられることにより、確実に床ずれを防止できる。また、空気セルがたとえ汚れた場合でも、空気セルを身体横方向の両側部からそれぞれ引出してカバー体とシート体との間からすぐ取出すことができ、清浄作業等のメンテナンスが容易に行え、清潔な状態も維持しやすい。
【００１０】
また、空気セルを小型中空体の連結で形成し、且つ、各小型中空体の連結部分に空気を通す絞り通路を形成し、小型中空体間の空気の流通を絞り通路で制限することにより、空気セルによる身体支持部位が小型中空体毎となって細分化され、身体を支持する面積が減少することとなり、身体とマット上面との密着をより一層抑えられ、床ずれの防止能力を向上させられると共に、人の動きで身体の重心位置が変化し、身体から空気セルに加わる圧力状態が急に変化した場合でも、空気セルの各小型中空体間の絞り通路を通じて空気がゆっくりと隣接する小型中空体へ移動し、空気セル各部の急激な落込みや膨張を防止でき、マット上の人に違和感や不安を与えずに確実に支持できる。
さらに、空気注入排出手段で隣合う空気セルは互いに異なるタイミングで、且つ隣合わない空気セルはほぼ同じタイミングでそれぞれ膨張、収縮させることにより、同時に膨張、収縮を行うセルが千鳥状配置となり、空気セルで身体を支える位置が適切に分散することとなり、身体をバランス良く支持できると共に、空気セルが身体を横断して圧迫することがなく、身体の血行が阻害されず、身体への悪影響を防ぎつつ床ずれ防止動作を行える。
【００１１】
また、本発明に係る床ずれ防止マットは必要に応じて、前記各空気セルが、前記カバー体における身体横方向の中間位置より端部寄りに配設され、シート体及びカバー体に対する身体横方向一端側寄りの各空気セルの連通路を前記一端側から外部に取出されて前記空気注入排出手段に接続されると共に、身体横方向他端側寄りの各空気セルの連通路を前記他端側から外部に取出されて前記空気注入排出手段に接続され、前記空気注入排出手段が、前記一端側寄りの空気セルと他端側寄りの空気セルについて異なる側では空気の注入もしくは排出の動作状態を異ならせるものである。
このように本発明においては、身体横方向に直列に配設される各空気セルが身体横方向一端側と他端側からそれぞれ独立に連通路を接続される形状に形成され、空気セルの膨張、収縮状態を身体横方向の中央から一端寄りの半分と他端寄りの半分で独立に調整可能とすることにより、身体横方向について身体の支持高さのバランスを変化させて身体の傾きを変化させられることとなり、体位の変換をはじめ、背中の清拭やオムツ交換等のマット上の人の身体を動かす作業の際に身体を動かし易くし、作業の能率を向上させられると共に、作業の省力化が図れる。
【００１３】
また、本発明に係る床ずれ防止マットは必要に応じて、前記空気セルの前記シート体及びカバー体の間への配設状態における身体横方向の側端位置で、空気セルと連通路との間に、空気セルと連通路とを着脱自在にする接続コネクタを配設するものである。
このように本発明においては、空気セルと連通路との間に接続コネクタを配設し、接続コネクタの着脱で空気セルと連通路との接続状態を切替えられることにより、空気セルのシート体及びカバー体の間に対する出し入れを空気セルと連通路との接続を一旦外した状態で行えることとなり、連通路及び各空気セルを個別に取扱うことができ、それぞれの交換等メンテナンスがより一層容易に行える。
【００１４】
【発明の実施の形態】
（本発明の第１の実施形態）
以下、本発明の第１の実施形態に係る床ずれ防止マットを図１ないし図６に基づいて説明する。図１は本実施の形態に係る床ずれ防止マットの平面図、図２は本実施の形態に係る床ずれ防止マットの分解斜視図、図３は本実施の形態に係る床ずれ防止マットの横断面図、図４は本実施の形態に係る床ずれ防止マットの床ずれ防止動作状態説明図、図５は本実施の形態に係る床ずれ防止マットの身体傾動動作状態説明図、図６は本実施の形態に係る床ずれ防止マットの身体傾動状態における横断面図である。
【００１５】
前記各図に示すように、本実施の形態に係る床ずれ防止マット１は、寝た姿勢の人の全身をその身体縦方向と長辺方向とを一致させる向きで載せられる略矩形状のシート体２と、このシート体２上に重ねられた状態でシート体２長手方向に所定間隔をなす複数箇所でシート体２にそれぞれ一体に固着され、各固着部位の中間部分を略トンネル状の収納部４とされるカバー体３と、可撓性を有する細長い略筒状の中空体で形成され、この中空体の中空部分に連通する連通路としての所定の管６１、６２、６３、６４が各々接続され、前記収納部４に二つ直列に挿入されてシート体２とカバー体３との間に複数並列状態に配設される流体セルとしての空気セル５１、５２、５３、５４と、この空気セル５１、５２、５３、５４に前記管６１、６２、６３、６４を介して接続され、各管６１、６２、６３、６４を通じて各空気セル５１、５２、５３、５４に対し空気を注入もしくは排出しつつ空気セル中の空気量を調整する空気注入排出手段（図示を省略）とを備える構成である。
【００１６】
前記カバー体３は、身体の重みや内側の空気セル５１、５２、５３、５４からの圧力が加わっても破損しない丈夫な可撓性素材製の矩形シート状体で形成され、シート体２上で空気セル５１、５２、５３、５４の幅に略一致する所定間隔をなす複数の固着部位でそれぞれシート体２と一体に固着され、各空気セル５１、５２、５３、５４をシート体２長手方向に動かないよう保持する一方、横方向の端部は固着されずにシート体２とカバー体３との間の空間が開放された状態であり、前記収納部４に対する空気セル５１、５２、５３、５４の挿入及び取出し口とされる構成である。
【００１７】
前記空気セル５１、５２、５３、５４は、空気注入排出に伴う変形に耐えうる可撓性素材製の中空体としてカバー体３の幅の略半分の長さとなる細長い略筒形状に成形され、カバー体３とシート体２との間の収納部４に横方向両側の開放部分からそれぞれ着脱自在に挿入されて配設され、空気注入排出手段による空気の注入排出で膨張収縮する構成である。各空気セルは、収納部４内で直列に並んで横方向に隣合う二つについて連通路となる管を別系統として互いに独立させて横方向端部からそれぞれ外部に引出されると共に、この管を縦方向の空気セル一つおきにそれぞれ合流させて横方向左側と右側のそれぞれで二系統ずつにまとめられて空気注入排出手段と接続される。すなわち、空気セル５１は管６１と、空気セル５２は管６２と、空気セル５３は管６３と、空気セル５４は管６４とそれぞれ連通し、四つの系統で空気注入排出手段によりそれぞれ独立して空気を注入、排出され、各々所定のタイミングで膨張、収縮する仕組みである。
【００１８】
次に、本実施の形態に係る床ずれ防止マットの床ずれ防止動作について説明する。まず、人がカバー体３上に身体全体を載せて寝ている状態で、管理者の操作により空気注入排出手段が動作を開始し、管６１、６４を介して空気セル５１、５４に空気を加圧注入し、空気セル５１、５４を膨張させる一方、管６２、６３を介して空気セル５２、５３から空気を排出し、空気セル５２、５３を収縮させる（図４参照）。空気セル５１、５４の膨張と空気セル５２、５３の収縮により、空気セル５２、５３の押圧力を減衰させて身体接触部分に押圧力を与えない状態になると共に、空気セル５１、５４の押圧力がカバー体３を介して身体接触部分に伝わるようになり、寝ている人の身体を空気セル５１、５４で支える状態となる。空気セル５１、５４並びに空気セル５２、５３がそれぞれ所定の圧力に達したら、空気注入排出手段が空気の注入、排出を一旦停止して圧力を維持する状態となる。
【００１９】
空気注入排出手段が空気セル５１、５２、５３、５４の圧力を維持する状態となって所定時間（例えば、１５分程度）経過すると、空気注入排出手段と管６１、６４及び管６２、６３との接続状態が切り替り、空気注入排出手段が管６２、６３に対し空気を注入し、且つ管６１、６４から空気を排出する状態となる。これにより前記と逆に空気注入排出手段が空気セル５２、５３を空気の注入で膨張させる一方、空気セル５１、５４を空気の排出により収縮させ、この空気セル５２、５３の膨張と空気セル５１、５４の収縮により、寝ている人の身体を支持する部分が空気セル５１、５４から空気セル５２、５３に入れ替る。空気セル５１、５４並びに空気セル５２、５３がそれぞれ所定の圧力に達したら、前記同様に空気注入排出手段が空気の注入、排出を一旦停止して圧力を維持する状態となる。
【００２０】
この後、空気注入排出手段の空気セル５１、５４並びに空気セル５２、５３に対する空気の注入排出が所定時間毎に注入排出の対象を前記同様に切替えつつ繰返し行われ、空気セル５１、５４もしくは空気セル５２、５３がそれぞれカバー体３上に寝ている人を支持することで、身体を支持する位置を断続的に変化させられ、身体と支持部位との接触が長時間継続するのを防げる。加えて、同時に膨張、収縮を行う空気セル５１、５４もしくは空気セル５２、５３が千鳥状配置となっており、寝ている人の支持位置が連続せず分散するため、身体に負担がかからない。
【００２１】
続いて、本実施の形態に係る床ずれ防止マットの身体傾動動作について説明する。空気注入排出手段に対する管理者の所定の操作で、空気注入排出手段が管６１、６４及び管６２、６３との接続状態を変え、空気注入排出手段が管６１、６２に対し空気を注入し、且つ管６３、６４から空気を排出する状態、もしくは、管６１、６２から空気を排出し、且つ管６３、６４に対し空気を注入する状態のいずれかとなる。
【００２２】
空気注入排出手段が管６１、６２を介して空気セル５１、５２に空気を注入し、空気セル５１、５２を膨張させる一方、管６３、６４を介して空気セル５３、５４から空気を排出し、空気セル５３、５４を収縮させる状態（図５参照）では、マット本体２の一方の空気セル５１、５２の膨張で寝ている人の右半身が上がる一方、他方の空気セル５３、５４の収縮で左半身が下がることから、マット上の人の身体全体を空気セル５３、５４の側に傾けられる（図６参照）。逆に、空気注入排出手段が空気セル５３、５４を空気の注入で膨張させる一方、空気セル５１、５２を空気の排出により収縮させる状態では、空気セル５３、５４の膨張で人の左半身が上がる一方、空気セル５１、５２の収縮で右半身が下がることから、人の身体全体を空気セル５１、５２の側に傾けられる。いずれの場合でも、空気セル５１、５２並びに空気セル５３、５４がそれぞれ所定の圧力に達したら、空気注入排出手段が空気の注入、排出を一旦停止して圧力を維持し、寝ている人を傾いた状態に保持できる。
【００２３】
このように、本実施の形態に係る床ずれ防止マットにおいては、シート体２とカバー体３との間に空気セル５１、５２、５３、５４が配設され、床ずれ防止動作として空気セル５１、５４並びに空気セル５２、５３に対する空気注入排出手段の空気の注入又は排出が所定時間毎に注入排出の対象を切替えながら繰返し行われ、空気セル５１、５４もしくは空気セル５２、５３がそれぞれカバー体３上に寝ている人を支持することから、身体の支持位置を断続的に変化させられ、身体とその支持部位との接触の長時間継続による床ずれを防止できると共に、同時に膨張、収縮を行う空気セル５１、５４もしくは空気セル５２、５３が千鳥状配置となって各位置で寝ている人を支持することから、空気セルによる支持部分が横方向に連続せず、寝ている人の身体縦方向の血行を阻害せず、身体に悪影響を与えない。また、身体傾動動作として空気注入排出手段が空気セル５１、５２と空気セル５３、５４とのいずれか一方には空気を注入し、他方から空気を排出して、寝ている人を横に傾けられることから、背中の清拭や体位の変換、オムツ交換等の寝ている人をマット上で傾ける必要のある作業を容易に行え、作業能率を向上させられると共に省力化が図れる。
【００２４】
（本発明の第２の実施形態）
本発明の第２の実施形態に係る床ずれ防止マットを図７ないし図１０に基づいて説明する。図７は本実施の形態に係る床ずれ防止マットの平面図、図８は本実施の形態に係る床ずれ防止マットの分解斜視図、図９は本実施の形態に係る床ずれ防止マットの横断面図、図１０は本実施の形態に係る床ずれ防止マットの空気セル内空気流通状態説明図である。
【００２５】
前記各図に示すように、本実施の形態に係る床ずれ防止マット１は、前記第１の実施形態同様に、シート体２と、カバー体３と、空気セル５１、５２、５３、５４と、空気注入排出手段（図示を省略）とを備える一方、異なる点として、各空気セル５１、５２、５３、５４が、三つの独立した小型中空体５０を直列に連結して形成されると共に、小型中空体５０同士を連通させ且つ通過する空気に対し所定の通過抵抗を与える絞り通路５０ａを各小型中空体５０の連結部分にそれぞれ形成される構成を有するものである。
【００２６】
次に、前記構成に基づく床ずれ防止マットの各空気セル内での空気流通状態について説明する。本実施の形態に係る床ずれ防止マットの床ずれ防止動作及び身体傾動動作における空気注入排出手段の動作は、前記第１の実施形態と同様であり、床ずれ防止動作として空気セル５１、５４並びに空気セル５２、５３に対する空気注入排出手段の空気の注入排出が所定時間毎に注入排出の対象を切替えながら繰返し行われ、また、身体傾動動作として空気注入排出手段が空気セル５１、５２と空気セル５３、５４とのいずれか一方への空気の注入、他方からの空気の排出をそれぞれ行う。
【００２７】
これらの各動作において、空気セル内に空気が注入される場合、管に接続された小型中空体５０に空気がまず供給され、空気がこの小型中空体５０で所定量に達した後、絞り通路５０ａを通って空気が次の小型中空体５０に達し、同様にして更に次の小型中空体５０まで空気が供給されることとなる。また、空気セル内から空気が排出される場合は、まず、管に接続された小型中空体５０から空気が排出され、空気がこの小型中空体５０で所定圧力まで減少した後、絞り通路５０ａを通って次の小型中空体５０内の空気が進入して排出され、同様にして更に次の小型中空体５０から空気が出て排出されることとなる。
【００２８】
各空気セルによる支持は、空気セルをなす各小型中空体５０がそれぞれ支持部位となって支持を分担するため、寝ている人の体重を分散してより安定して支持できる。また、寝ている人が寝た姿勢で動いた場合、人の重心位置が変り、各空気セル上においても加わる押圧力の位置や強さが変化するが、新たに押圧力が加わる箇所となった小型中空体５０から連通する他の小型中空体５０に空気が移動する場合、空気は通過抵抗のある絞り通路５０ａを通ってゆっくり移動し（図１０参照）、小型中空体５０の急激な体積変化を抑えることから、空気セルの外部からの圧力が集中する位置での急激な落込みやそれ以外の箇所での急な膨らみを防止でき、空気セル上での揺れを少なくして寝ている人をその姿勢に応じて安定的に支持できる。
【００２９】
このように、本実施の形態に係る床ずれ防止マットにおいては、空気セルが小型中空体５０を連結させて形成され、身体を支持する部位を増やしながら支持面積を減らし、さらに同一空気セルの小型中空体５０同士を絞り通路５０ａにより連通させ、小型中空体５０間の空気の急速な移動を絞り通路５０ａで制限することから、支持のために身体に密着する部分が減少し、身体の血行が阻害されず床ずれ防止効果を向上させられると共に、身体のちょっとした動きで身体からの押圧力が空気セルの一部分に加わった場合でも、空気セル各部の急激な落込みや膨らみを防止でき、上に寝ている人に違和感や不安を与えずに確実に支持でき、快適性の向上が図れる。
【００３０】
なお、前記第１及び第２の各実施形態に係る床ずれ防止マットにおいて、シート体２とカバー体３との間に複数並列状態に配設される空気セル５１、５２、５３、５４は身体横方向の中心に対しそれぞれ左右に独立して配置される構成としているが、これに限らず、図１１に示すように、シート体２とカバー体３との間における身体縦方向の端部側などで、より長寸法の空気セル５５を身体横方向には一つのみとして配設する構成とすることもでき、頭部や足先など、さほど傾ける必要がない箇所を、空気セルが横方向に連続することで安定的に支持可能となる。
【００３１】
また、前記第１及び第２の各実施形態に係る床ずれ防止マットにおいて、空気セル５１、５２、５３、５４と連通路としての管６１、６２、６３、６４とはそれぞれ直結される構成としているが、これに限らず、図１２に示すように、空気セル５１、５３と管６１、６３との間に公知の接続コネクタ７０を配設し、空気セル５１、５３と管６１、６３とを着脱自在にする構成とすることもでき、接続コネクタ７０の着脱で管６１、６３及び空気セル５１、５３を個別に取扱うことができ、それぞれの交換等を始めとするメンテナンス作業が容易に行える。
【００３２】
【発明の効果】
以上のように本発明によれば、空気を中空部分に出入りさせられる複数の空気セルが、シート体とカバー体との間に身体横方向へ直列に二つずつ挿入されながら身体縦方向に複数並列させて配設され、空気注入排出手段を作動させて各空気セル毎に膨張、収縮を所定時間間隔で繰返させ、カバー体上の人の身体各部分への接触位置を所定時間間隔で次々に変えられることにより、確実に床ずれを防止できるという効果を奏する。また、空気セルがたとえ汚れた場合でも、空気セルを身体横方向の両側部からそれぞれ引出してカバー体とシート体との間からすぐ取出すことができ、清浄作業等のメンテナンスが容易に行え、清潔な状態も維持しやすいという効果を有する。
【００３３】
また、本発明によれば、空気セルを小型中空体の連結で形成し、且つ、各小型中空体の連結部分に空気を通す絞り通路を形成し、小型中空体間の空気の流通を絞り通路で制限することにより、空気セルによる身体支持部位が小型中空体毎となって細分化され、身体を支持する面積が減少することとなり、身体とマット上面との密着をより一層抑えられ、床ずれの防止能力を向上させられると共に、人の動きで身体の重心位置が変化し、身体から空気セルに加わる圧力状態が急に変化した場合でも、空気セルの各小型中空体間の絞り通路を通じて空気がゆっくりと隣接する小型中空体へ移動し、空気セル各部の急激な落込みや膨張を防止でき、マット上の人に違和感や不安を与えずに確実に支持できるという効果を有する。
【００３４】
また、本発明によれば、身体横方向に直列に配設される各空気セルが身体横方向一端側と他端側からそれぞれ独立に連通路を接続される形状に形成され、空気セルの膨張、収縮状態を身体横方向の中央から一端寄りの半分と他端寄りの半分で独立に調整可能とすることにより、身体横方向について身体の支持高さのバランスを変化させて身体の傾きを変化させられることとなり、体位の変換をはじめ、背中の清拭やオムツ交換等のマット上の人の身体を動かす作業の際に身体を動かし易くし、作業の能率を向上させられると共に、作業の省力化が図れるという効果を有する。
【００３５】
また、本発明によれば、身体縦方向に並列する空気セル一つおきにその連通路を同時に注入、排出可能にまとめ、空気注入排出手段で身体縦方向及び横方向に隣合う空気セルは互いに異なるタイミングで、且つ隣合わない空気セルはほぼ同じタイミングでそれぞれ膨張、収縮させることにより、同時に膨張、収縮を行うセルが千鳥状配置となり、空気セルで身体を支える位置が適切に分散することとなり、身体をバランス良く支持できると共に、空気セルが身体を横断して圧迫することがなく、身体の縦方向の血行が阻害されず、身体への悪影響を防ぎつつ床ずれ防止動作を行えるという効果を有する。
【００３６】
また、本発明によれば、空気セルと連通路との間に接続コネクタを配設し、接続コネクタの着脱で空気セルと連通路との接続状態を切替えられることにより、空気セルのシート体及びカバー体の間に対する出し入れを空気セルと連通路との接続を一旦外した状態で行えることとなり、連通路及び各空気セルを個別に取扱うことができ、それぞれの交換等メンテナンスがより一層容易に行えるという効果を有する。

An example of such an air mat type floor slip prevention mat is shown in FIG. FIG. 13 is a perspective view of a conventional floor slip prevention mat.
[0003]
The conventional floor slip prevention mat 100 shown in the previous figure is formed of a substantially sheet-like base mat 101 and an elongated hollow body. A plurality of base mats 101 are mounted in parallel on the base mat 101 and inflated by injecting and discharging air. A plurality of air cells 102 that contract, an antifouling sheet 103 disposed so as to cover the air cells 102, and air injection / discharge for performing pressure injection or suction discharge of air to each air cell 102 via a tube 104 And a device (not shown).
[0004]
In this conventional floor slip prevention mat 100, when the air injecting and discharging device operates while a person is lying on the antifouling sheet 103, the air cells 102 are appropriately switched between injecting and discharging air. The expansion / contraction state of the body is adjusted, and when it expands, it generates a predetermined support force to the body and releases the support state during contraction, and touches the human body from the shoulder to the back and from the waist to the legs while touching at multiple contact positions. Can be prevented at a predetermined timing to prevent a state of close contact and prevent bed slipping.
[0005]
[Problems to be solved by the invention]
Since the conventional floor slip prevention mat is configured as described above, the air cell 102 does not become dirty when the antifouling sheet 103 completely covers the air cell 102, as shown in FIG. The antifouling sheet 103 may be displaced by the movement of a person on the antifouling sheet 103, and the air cell 102 may be exposed. When the antifouling sheet 103 is displaced and the person sleeping without covering the air cell 102 has incontinence or the like, there is a problem that the filth enters the air cell 102.
[0006]
When removing the filth that has entered between the air cells 102, the air cells 102 are normally inflated while the air cells 102 are inflated because the air cells 102 cannot be removed and the removal operation cannot be performed. Even if the air cell contracted and collapsed, it was difficult to remove the dirt by turning the air cell one by one. On the other hand, once the air cell 102 is removed from the base mat 101 and cleaning is performed, the dirt can be reliably removed, but it takes time and effort to remove the air cell 102 from the connection opening to the tube 104 during cleaning. When water enters easily when water enters, it has problems such as clogging of the pipe 104 that sends air during use, abnormal noise in the air cell 102, and strange odor when air is discharged from the air cell 102. .
[0007]
In addition, the conventional bed slip mat is a mechanism that prevents the bed slip by changing the support position by alternately expanding and contracting the adjacent air cells 102 in parallel, but since it becomes a wavy body pressure support, There was a problem that there was a risk of pulling the skin of a person sleeping on the mat and causing slippage or friction. In addition, since the expanded air cell 102 is continuously in contact with the body in the lateral direction, the blood flow in the longitudinal direction is divided by compression, the blood circulation in the longitudinal direction of the body is deteriorated, and the physical condition is adversely affected. It had the problem that.
[0008]
The present invention has been made to solve the above-mentioned problems, and a plurality of air cells are arranged in the transverse direction of the mat to facilitate maintenance, and the support position of the body on the mat can be appropriately arranged, so that the bed slippage can be prevented. An object of the present invention is to provide a bed slip prevention mat that can adjust a sleeping person to a predetermined posture.
[0009]
[Means for Solving the Problems]
The floor slip prevention mat according to the present invention includes a sheet body that is formed to have a size that allows the whole body of a person in a sleeping position to be placed thereon, and a flexible cover body that is disposed on the upper surface side of the sheet body. And a plurality of hollow air cells arranged in parallel between the sheet body and the cover body, and air injection / discharge means connected to the air cells via a communication path communicating with the hollow portion of the air cells In the floor slip prevention mat, the air injection / discharge means repeatedly injects and discharges air through the communication path for each air cell while switching between the injection target and the discharge target, and expands and contracts the air cell. The air cell is formed by connecting a plurality of independent substantially cubic small hollow bodies in series, and each of the throttle passages that communicate the small hollow bodies and provide passage resistance to the air passing therethrough. Small hollow body Each of the small hollow bodies is formed at the connecting portion, and the small hollow bodies are arranged apart from each other except for the connecting portion having the throttle passage, and the air cell is adjacent between the sheet body and the cover body. For the two arranged in parallel, the communication path is made a separate system, the communication paths for the plurality of air cells are merged respectively to be combined into two systems and connected to the air injection / discharge means, and the plurality of air cells expand at the same time, The air injecting / exhausting means changes the operating state of injecting or exhausting air to different communication paths communicating with adjacent air cells.
Thus, in the present invention, a plurality of air cells that allow air to enter and exit the hollow portion are arranged in parallel between the sheet body and the cover body, and each air cell is operated by operating the air injection / discharge means. Each time the expansion and contraction are repeated at predetermined time intervals, and the contact positions of the human body on the cover body can be successively changed at predetermined time intervals, bed slip can be reliably prevented. Even if the air cell is dirty, the air cell can be pulled out from both sides in the lateral direction of the body and taken out immediately between the cover body and the sheet body, making maintenance such as cleaning work easy and clean. Easy to maintain.
[0010]
Further, by forming an air cell by connecting small hollow bodies, and forming a throttle passage through which air passes through the connecting portions of each small hollow body, and restricting the flow of air between the small hollow bodies by the throttle passage, The body support site by the air cell is subdivided into small hollow bodies, the area supporting the body is reduced, the adhesion between the body and the top surface of the mat can be further suppressed, and the ability to prevent bedsores can be improved. In addition, even if the position of the center of gravity of the body changes due to the movement of the person and the pressure state applied from the body to the air cell suddenly changes, the small hollow where the air slowly adjoins through the throttle passage between each small hollow body of the air cell It can move to the body, prevent sudden drop and expansion of each part of the air cell, and can be reliably supported without giving a sense of discomfort or anxiety to the person on the mat.
Furthermore, the adjacent air cells in the air injection / discharge means are expanded and contracted at different timings, and the non-adjacent air cells are expanded and contracted at substantially the same timing, so that the cells that simultaneously expand and contract are arranged in a staggered manner. The position where the body is supported by the cell will be properly distributed, the body can be supported in a well-balanced manner, the air cell will not be compressed across the body, blood circulation of the body will not be inhibited, and adverse effects on the body will be prevented It is possible to prevent bed slipping.
[0011]
Further, in the floor slip prevention mat according to the present invention, if necessary, each air cell is disposed closer to the end than an intermediate position in the body lateral direction of the cover body, and one end in the body lateral direction with respect to the sheet body and the cover body. The communication path of each air cell near the side is taken out from the one end side and connected to the air injection / discharge means, and the communication path of each air cell near the other side in the lateral direction of the body is connected from the other end side. It is taken out to the outside and connected to the air injection / discharge means, and the air injection / discharge means has different air injection or discharge operation states on different sides of the air cell near the one end side and the air cell near the other end side. It is something to make.
Thus, in the present invention, each air cell arranged in series in the lateral direction of the body is formed in a shape in which the communication path is independently connected from one end side and the other end side in the lateral direction of the body, and the expansion of the air cell The contraction state can be adjusted independently from the center in the lateral direction at the half near the one end and the other half near the other end, thereby changing the balance of the body support height in the lateral direction of the body and changing the tilt of the body This makes it easier to move the body when moving the person's body on the mat, such as changing the posture, wiping the back, changing diapers, etc., improving work efficiency and saving labor. Can be achieved.
[0013]
Further, the floor slip prevention mat according to the present invention is provided between the air cell and the communication path at the lateral end position in the lateral direction of the body when the air cell is disposed between the sheet body and the cover body. In addition, a connection connector that allows the air cell and the communication path to be freely attached and detached is provided.
As described above, in the present invention, the connection connector is disposed between the air cell and the communication path, and the connection state between the air cell and the communication path can be switched by attaching and detaching the connection connector. The connection between the cover body and the air cell can be performed with the connection between the air cell and the communication path once disconnected. The communication path and each air cell can be handled individually, and maintenance such as replacement can be performed more easily. .

It is a cross-sectional view in the body tilting state of the prevention mat.
[0015]
As shown in the respective drawings, the bed slip prevention mat 1 according to the present embodiment is a substantially rectangular sheet body on which the whole body of a sleeping person can be placed in a direction in which the body longitudinal direction and the long side direction coincide with each other. 2 and in a state of being stacked on the sheet body 2, the sheet body 2 is integrally fixed to the sheet body 2 at a plurality of positions at a predetermined interval in the longitudinal direction, and an intermediate portion of each fixing portion is formed in a substantially tunnel-shaped storage section. 4 and a cover body 3 having a flexible and long and substantially cylindrical hollow body, and predetermined pipes 61, 62, 63, and 64 as communication passages communicating with the hollow portion of the hollow body, respectively. Air cells 51, 52, 53, 54 as fluid cells that are connected and inserted in series in the storage portion 4 and arranged in parallel between the sheet body 2 and the cover body 3, The pipes 61, 62 are connected to the air cells 51, 52, 53, 54. 63, 64 is connected to the air cells 51, 52, 53, 54 through the pipes 61, 62, 63, 64, and air is injected or discharged to adjust the amount of air in the air cells. Means (not shown).
[0016]
The cover body 3 is formed of a rectangular sheet-like body made of a strong and flexible material that is not damaged even when the weight of the body or the pressure from the inner air cells 51, 52, 53, 54 is applied. Are fixed integrally with the sheet body 2 at a plurality of fixing portions having a predetermined interval substantially matching the width of the air cells 51, 52, 53, 54, and the air cells 51, 52, 53, 54 are fixed to the longitudinal direction of the sheet body 2. While holding so as not to move in the direction, the lateral ends are not fixed, and the space between the sheet body 2 and the cover body 3 is open, and the air cells 51, 52, It is the structure used as the insertion and extraction opening of 53,54.
[0017]
The air cells 51, 52, 53, 54 are formed in a substantially elongated cylindrical shape that is approximately half the width of the cover body 3 as a hollow body made of a flexible material that can withstand deformation due to air injection and discharge, The storage unit 4 between the cover body 3 and the sheet body 2 is detachably inserted from the open portions on both sides in the lateral direction, and is expanded and contracted by air injection / discharge by air injection / discharge means. Each air cell is pulled out to the outside from the end in the lateral direction, with the pipes that are connected in series in the storage unit 4 and are connected to each other in the horizontal direction as separate systems. Are merged into every other air cell in the vertical direction, and are combined into two systems on the left and right sides in the horizontal direction and connected to the air injection / discharge means. That is, the air cell 51 communicates with the tube 61, the air cell 52 communicates with the tube 62, the air cell 53 communicates with the tube 63, and the air cell 54 communicates with the tube 64, respectively. Air is injected and discharged, and each expands and contracts at a predetermined timing.
[0018]
Next, the floor slip prevention operation of the floor slip prevention mat according to the present embodiment will be described. First, in a state where a person is lying on the cover body 3 and sleeping, the air injecting and discharging means starts operating by the operation of the administrator, and air is supplied to the air cells 51 and 54 through the tubes 61 and 64. While injecting under pressure, the air cells 51 and 54 are expanded, while air is discharged from the air cells 52 and 53 through the pipes 62 and 63 to contract the air cells 52 and 53 (see FIG. 4). The expansion of the air cells 51 and 54 and the contraction of the air cells 52 and 53 attenuate the pressing force of the air cells 52 and 53 so that no pressing force is applied to the body contact portion. The pressure is transmitted to the body contact portion through the cover body 3, and the body of the sleeping person is supported by the air cells 51 and 54. When each of the air cells 51 and 54 and the air cells 52 and 53 reaches a predetermined pressure, the air injection / discharge means temporarily stops the air injection / discharge and maintains the pressure.
[0019]
When a predetermined time (for example, about 15 minutes) elapses when the air injection / discharge means maintains the pressure of the air cells 51, 52, 53, 54, the air injection / discharge means and the tubes 61, 64 and the tubes 62, 63 The connection state is switched, and the air injection / discharge means injects air into the tubes 62 and 63 and discharges air from the tubes 61 and 64. Thus, contrary to the above, the air injection / discharge means expands the air cells 52, 53 by injecting air, while the air cells 51, 54 contract by discharging air, and the expansion of the air cells 52, 53 and the air cell 51 , 54, the portion supporting the sleeping person's body is replaced with the air cells 52, 53 from the air cells 51, 54. When each of the air cells 51 and 54 and the air cells 52 and 53 reaches a predetermined pressure, the air injection / discharge means temporarily stops the injection and discharge of air and maintains the pressure as described above.
[0020]
Thereafter, the air cells 51 and 54 of the air injection and discharge means and the air cells 52 and 53 are repeatedly injected and discharged every predetermined time while switching the target of injection and discharge in the same manner as described above. The cells 52 and 53 each support the person sleeping on the cover body 3, so that the position of supporting the body can be changed intermittently, and the contact between the body and the support portion can be prevented from continuing for a long time. In addition, the air cells 51 and 54 or the air cells 52 and 53 that expand and contract at the same time are arranged in a staggered manner, and the support positions of the sleeping person are not continuously distributed, so that the body is not burdened.
[0021]
Next, the body tilting operation of the floor slip prevention mat according to the present embodiment will be described. The air injection / discharge means changes the connection state between the pipes 61 and 64 and the pipes 62 and 63, and the air injection / discharge means injects air into the pipes 61 and 62 by a predetermined operation of the administrator for the air injection / discharge means. In addition, either the state in which air is discharged from the tubes 63 and 64 or the state in which air is discharged from the tubes 61 and 62 and air is injected into the tubes 63 and 64 is set.
[0022]
The air injection / discharge means injects air into the air cells 51 and 52 via the pipes 61 and 62 and expands the air cells 51 and 52, while discharging air from the air cells 53 and 54 via the pipes 63 and 64. In the state in which the air cells 53 and 54 are contracted (see FIG. 5), the right half of the person sleeping is raised by the expansion of one air cell 51 and 52 of the mat body 2, while the other air cell 53 and 54 Since the left half body is lowered by the contraction, the whole body of the person on the mat is tilted toward the air cells 53 and 54 (see FIG. 6). On the contrary, in the state where the air injection and discharge means expands the air cells 53 and 54 by injecting air, while the air cells 51 and 52 contract by the discharge of air, the expansion of the air cells 53 and 54 causes the left half of the person to On the other hand, since the right half of the body is lowered by contraction of the air cells 51 and 52, the entire human body is tilted toward the air cells 51 and 52. In any case, when the air cells 51, 52 and the air cells 53, 54 reach a predetermined pressure, the air injection / discharge means temporarily stops the air injection / discharge to maintain the pressure and Can be held in an inclined state.
[0023]
Thus, in the floor slip prevention mat according to the present embodiment, the air cells 51, 52, 53, 54 are disposed between the sheet body 2 and the cover body 3, and the air cells 51, 54 are used as a floor slip prevention operation. In addition, the air injection or discharge of the air injection / discharge means with respect to the air cells 52 and 53 is repeatedly performed while switching the target of injection and discharge every predetermined time, and the air cells 51 and 54 or the air cells 52 and 53 are respectively placed on the cover body 3. Supporting a person who is sleeping on the air cell, the support position of the body can be changed intermittently to prevent bed slippage due to long-lasting contact between the body and its support part, and at the same time expand and contract 51, 54 or air cells 52, 53 are arranged in a staggered pattern to support a person sleeping at each position. Does not inhibit the body in the vertical direction of the circulation of the person you are, it does not adversely affect the body. Further, as a body tilting operation, the air injection / discharge means injects air into one of the air cells 51, 52 and the air cells 53, 54, discharges air from the other, and tilts the sleeping person sideways. Therefore, it is possible to easily perform work that needs to tilt the sleeping person on the mat, such as wiping the back, changing the posture, changing diapers, etc., improving work efficiency and saving labor.
[0024]
(Second embodiment of the present invention)
A floor slip prevention mat according to a second embodiment of the present invention will be described with reference to FIGS. 7 is a plan view of the floor slip prevention mat according to the present embodiment, FIG. 8 is an exploded perspective view of the floor slip prevention mat according to the present embodiment, and FIG. 9 is a cross-sectional view of the floor slip prevention mat according to the present embodiment. FIG. 10 is an explanatory diagram of the air circulation state in the air cell of the floor slip prevention mat according to the present embodiment.
[0025]
As shown in the drawings, the floor slip prevention mat 1 according to the present embodiment is similar to the first embodiment in that the sheet body 2, the cover body 3, the air cells 51, 52, 53, 54, The air cells 51, 52, 53, and 54 are formed by connecting three independent small hollow bodies 50 in series while being provided with air injection / discharge means (not shown). A throttle passage 50 a that allows the hollow bodies 50 to communicate with each other and gives a predetermined passage resistance to the air passing therethrough is formed in a connecting portion of each small hollow body 50.
[0026]
Next, the air circulation state in each air cell of the floor slip prevention mat based on the above configuration will be described. The operation of the air injecting and discharging means in the floor slip prevention operation and the body tilting operation of the floor slip prevention mat according to the present embodiment is the same as in the first embodiment, and the air cells 51 and 54 and the air cell 52 are used as the floor slip prevention operation. , 53 are repeatedly injected and discharged by the air injecting and discharging means at every predetermined time while switching the target of injecting and discharging, and as the body tilting operation, the air injecting and discharging means is operated by the air cells 51 and 52 and the air cells 53 and 54. The air is injected into one of the two, and the air is discharged from the other.
[0027]
In each of these operations, when air is injected into the air cell, the air is first supplied to the small hollow body 50 connected to the pipe, and after the air reaches a predetermined amount in the small hollow body 50, the throttle passage Air reaches the next small hollow body 50 through 50a, and air is supplied to the next small hollow body 50 in the same manner. When air is discharged from the air cell, first, air is discharged from the small hollow body 50 connected to the pipe. After the air is reduced to a predetermined pressure by the small hollow body 50, the throttle passage 50a is opened. Then, the air in the next small hollow body 50 enters and is discharged, and similarly, air is further discharged from the next small hollow body 50 and discharged.
[0028]
Support by each air cell can be supported more stably by dispersing the weight of the sleeping person because each small hollow body 50 forming the air cell serves as a support site and shares the support. In addition, when a sleeping person moves in a sleeping posture, the position of the center of gravity of the person changes and the position and strength of the pressing force applied on each air cell also changes, but this is where new pressing force is applied. When air moves from the small hollow body 50 to another small hollow body 50 communicating with the small hollow body 50, the air slowly moves through the throttle passage 50a having passage resistance (see FIG. 10). Suppresses the change, so it can prevent a sudden drop at a position where pressure from the outside of the air cell is concentrated and a sudden bulge in other places, and sleeps with less shaking on the air cell. A person can be supported stably according to their posture.
[0029]
As described above, in the floor slip prevention mat according to the present embodiment, the air cell is formed by connecting the small hollow body 50, the support area is reduced while increasing the number of parts supporting the body, and the small hollow of the same air cell is further formed. Since the bodies 50 communicate with each other by the throttle passage 50a and the rapid movement of the air between the small hollow bodies 50 is restricted by the throttle passage 50a, the portion that is in close contact with the body for support is reduced and the blood circulation of the body is inhibited. In addition to improving the bed slip prevention effect, even if a small amount of body movement exerts a pressing force on the part of the air cell, it can prevent sudden drop and bulge of each part of the air cell, and sleep on top It is possible to support the person without feeling discomfort and anxiety and improve comfort.
[0030]
In the floor slip prevention mat according to each of the first and second embodiments, a plurality of air cells 51, 52, 53, 54 arranged in parallel between the sheet body 2 and the cover body 3 are lateral to the body. Although it is set as the structure arrange | positioned independently on each right and left with respect to the center of a direction, as shown in FIG. 11, the edge part side of the body vertical direction between the sheet | seat body 2 and the cover body 3, etc. Therefore, the air cell 55 having a longer dimension can be arranged as only one in the lateral direction of the body. It can be supported stably by being continuous.
[0031]
Further, in the bed slip prevention mats according to the first and second embodiments, the air cells 51, 52, 53, 54 and the pipes 61, 62, 63, 64 as communication paths are directly connected to each other. However, the present invention is not limited to this, and as shown in FIG. 12, a known connection connector 70 is disposed between the air cells 51 and 53 and the pipes 61 and 63, and the air cells 51 and 53 and the pipes 61 and 63 are connected. It can also be configured to be detachable, and the pipes 61 and 63 and the air cells 51 and 53 can be handled individually by attaching and detaching the connection connector 70, and maintenance work including replacement and the like can be easily performed.
[0032]
【The invention's effect】
As described above, according to the present invention, a plurality of air cells that allow air to enter and leave the hollow portion are inserted in series in the body transverse direction between the sheet body and the cover body, and two in the body longitudinal direction. Arranged in parallel, the air injecting and discharging means are operated to expand and contract each air cell at predetermined time intervals, and the contact positions of the human body parts on the cover body are successively set at predetermined time intervals. By changing to, it is possible to reliably prevent bed slipping. Even if the air cell is dirty, the air cell can be pulled out from both sides in the lateral direction of the body and taken out immediately between the cover body and the sheet body, making maintenance such as cleaning work easy and clean. It has the effect that it is easy to maintain a simple state.
[0033]
Further, according to the present invention, the air cell is formed by connecting small hollow bodies, and a throttle passage through which air is passed is formed in the connecting portion of each small hollow body, and the flow of air between the small hollow bodies is reduced. By limiting the body support area by the air cell for each small hollow body, the area supporting the body is reduced, the adhesion between the body and the top surface of the mat can be further suppressed, and floor slippage can be suppressed. In addition to improving the prevention capability, even if the position of the center of gravity of the body changes due to the movement of a person and the pressure state applied from the body to the air cell suddenly changes, the air flows through the constricted passage between each small hollow body of the air cell. Slowly moving to the adjacent small hollow body, it is possible to prevent sudden drop and expansion of each part of the air cell, and it has an effect that it can be surely supported without giving a sense of incongruity or anxiety to the person on the mat.
[0034]
Further, according to the present invention, each air cell arranged in series in the body lateral direction is formed in a shape in which the communication passage is independently connected from one end side and the other end side in the body lateral direction, and the expansion of the air cell The contraction state can be adjusted independently from the center in the lateral direction at the half near the one end and the other half near the other end, thereby changing the balance of the body support height in the lateral direction of the body and changing the tilt of the body This makes it easier to move the body when moving the person's body on the mat, such as changing the posture, wiping the back, changing diapers, etc., improving work efficiency and saving labor. It has the effect that it can be achieved.
[0035]
In addition, according to the present invention, every other air cell arranged in parallel in the body longitudinal direction can be infused and ejected at the same time, and the air cells adjacent to each other in the body longitudinal direction and the lateral direction by the air injecting and discharging means are mutually connected. By expanding and contracting air cells that are not adjacent to each other at different timings, the cells that expand and contract at the same time are arranged in a staggered manner, and the positions that support the body in the air cells are appropriately dispersed. The body can be supported in a well-balanced manner, and the air cell is not compressed across the body, the blood circulation in the longitudinal direction of the body is not obstructed, and the bedsore prevention operation can be performed while preventing adverse effects on the body. .
[0036]
Further, according to the present invention, the connection connector is disposed between the air cell and the communication path, and the connection state between the air cell and the communication path can be switched by attaching and detaching the connection connector. The connection between the cover body and the air cell can be performed with the connection between the air cell and the communication path once disconnected. The communication path and each air cell can be handled individually, and maintenance such as replacement can be performed more easily. It has the effect.
