【発明の属する技術分野】
本発明は、健常者には、より快適な敷物装置を提供すると共にかかる健常者から、床ずれ予防、治療を要する患者に至るまで使用者に合わせて反発性を調整して、単独で使うことは勿論、既存の寝具と組み合わせて使うことができるようにした、敷物装置に関するものである。
【０００２】
【従来の技術】
高齢化社会に突入した現在、寝たきり等の入院患者数の増加と共に、褥瘡（じょくそう：床ずれ）発生の危険の高い患者が増加している。
以前、本出願人は、褥瘡対策を施したマットレスとして例えば特開平１１−１３７６１３号を提案している。この場合のマットレスでは、二層構造としており、通常使用対応の、比較的硬質素材で構成した第１マットレス（図示省略）と、床ずれ対策を施した例えば軟質な低反発ウレタンを用いた第２マットレス（図示省略）とを積層すると共に、これら第１マットレスと第２マットレスとを、表地に一体収容する構成としている。
前記マットレスによれば、床ずれ予防、治療を要する患者のみならず、健常者用のマットレスとしても使うことができるものとなっている。
また最近、本出願人は、ベッド上に限らず、和室に敷いた布団での使用も可能とした敷物を提案している。
かかる敷物によれば、病院内に限らず、在宅においても、より褥瘡の発生予防に効果を発揮するものであるので、高齢化社会に呼応した有効な褥瘡対策であるといえる。
【０００３】
【発明が解決しようとする課題】
このように、上記敷物は、床ずれ予防、治療を要する患者用としてのものであるので、広く健常者から患者、老人が使えるような敷物は未だ見受けられない。そのためには、使用者個々の好み、あるいは傷病状況に応じるには、前記敷物の固さの調整がきくようにすることで達成可能であると考えられる。
本発明はこのような背景から提案されたものであって、健常者には、より快適な敷物装置を提供すると共にかかる健常者から、床ずれ予防、治療を要する患者に至るまで使用者に合わせて反発性を調整して、単独で使うことは勿論、既存の寝具と組み合わせて使うことができ、褥瘡対策にも呼応した、敷物装置を提供することを目的とする。

【００１５】
【発明の実施の態様】
以下、本発明にかかる敷物装置につき、一つの実施の態様を示し、添付の図面に基づいて説明する。
図１に敷物１を示す。この敷物１は、軟質性素材を用いた複数の分割片２ａ，２ｂ，２ｃ，２ｄ，２ｅで構成して、これら複数の分割片２ａ〜２ｅを人体が仰臥可能な長さ寸法、幅寸法の袋状表地３内に一体収容して構成している。
【００１６】
前記分割片２ａ〜２ｅは、略台形状に形成され、分割片２ａには傾斜面ＳＬａ、分割片２ｂには傾斜面ＳＬｂ１、ＳＬｂ２、分割片２ｃには傾斜面ＳＬｃ１、ＳＬｃ２、分割片２ｄには傾斜面ＳＬｄ１、ＳＬｄ２、分割片２ｅには傾斜面ＳＬｅがそれぞれ形成されている。
そして、分割片２ａの傾斜面ＳＬａと分割片２ｂの傾斜面ＳＬｂ１とを対向させ、分割片２ｂの傾斜面ＳＬｂ２と分割片２ｃの傾斜面ＳＬｃ１とを対向させ、分割片２ｃの傾斜面ＳＬｃ２と分割片２ｄの傾斜面ＳＬｄ１とを対向させ、分割片２ｄの傾斜面ＳＬｄ２と分割片２ｅの傾斜面ＳＬｅとを対向させ、頭側の分割片２ａから足側の分割片２ｅまで、前記傾斜面ＳＬａ〜ＳＬｅが互いに重なり合うように配列している。これら傾斜面ＳＬａ〜ＳＬｅの傾斜角度は、図２に示すように、分割片２ａの傾斜面ＳＬａと分割片２ｂの傾斜面ＳＬｂ１とは、右下がり略４５°傾斜させ、分割片２ｂの傾斜面ＳＬｂ２と分割片２ｃの傾斜面ＳＬｃ１とは、右上がり略４５°傾斜させ、分割片２ｃの傾斜面ＳＬｃ２と分割片２ｄの傾斜面ＳＬｄ１とは右下がり略４５°、さらに分割片２ｄの傾斜面ＳＬｄ２と分割片２ｅの傾斜面ＳＬｅとは右上がり略４５°というように、交互に逆に傾斜させている。
【００１７】
そして前記分割片２ａ〜２ｅは、それぞれ異なる反発性の軟質性素材で構成したものを備えており、それぞれ選択的に前記表地３内に収容して、敷物１として全体的、または要部の反発性を調整可能としている。
軟質性素材としては、例えば厚さ３０ｍｍ〜７０ｍｍ、見掛け密度が１０ｋｇ／ｍ３〜１００ｋｇ／ｍ３、圧縮硬さが１０Ｎ〜４００Ｎのウレタンフォーム材を用いることができ、かかる範囲内の軟質性素材を用いて、反発性の異なった分割片として構成している。また軟質性素材としては、フォームラバーも可能である。なお、かかる敷物１は、勿論、５つの分割片２ａ〜２ｅに限らず、３つ、あるいは６つ以上に多分割された分割片（図示省略）で構成することもできる。
【００１８】
また前記表地３には、伸縮性のある布部材を用いている。また、伸縮性と共に撥水性、または防水性を有する布地を用いることもできる。かかる表地３は長手方向側面側にファスナ（図示省略）を設けて、前記分割片２ａ〜２ｅを表地３内に出し入れ交換容易に一体収容するようにしている。
【００１９】
以上のような敷物１によれば、使用者の身体状況や嗜好に応じて反発性の異なる分割片２ａ〜２ｅを表地３内に適宜入れ替えて、その使用者に対応した反発性に調整することができる。
その際、分割片２ａ〜２ｅは、互いに対向する傾斜面ＳＬａ〜ＳＬｅが交互に逆に略４５°傾斜させ、表地３内に納めた際、前記傾斜面ＳＬａ〜ＳＬｅを介して接触しているので、ずれにくく安定性がある。
前記分割片２ａ〜２ｅには、例えば厚さ３０ｍｍ〜７０ｍｍ、見掛け密度が１０ｋｇ／ｍ３〜１００ｋｇ／ｍ３、圧縮硬さが１０Ｎ〜４００Ｎの範囲のウレタンフォーム材を用いて、反発性を相違させているので、健常者は勿論、床ずれ対策を要する患者まで対応させることができる。特に床ずれ対策を要する患者が使用する場合、体圧のかかる肩甲骨周辺や、仙骨周辺に対応する分割片２ｂ，２ｃは、その使用者に応じて、他の箇所に比較して体圧分散性の効果の高い反発性のものを選択するようにする。
【００２０】
また、前記敷物１の詰め物としての分割片２ａ〜２ｅは単層であるので扱いやすく、ベッドＢのマットレスＭ上に載置して、前記敷物１とマットレスＭとをカバー部材４により被覆して使用することができる（図３参照）。その際、分割片２ａ〜２ｅは、表地３内に納めた際、互いに傾斜面ＳＬａ〜ＳＬｅを介して接触しているので、ずれにくく安定性がある。この場合も分割片２ａ〜２ｅを表地３内に適宜入れ替えて、健常者は勿論、床ずれ対策を要する患者に対応した反発性に調整することができる。
これにより、ベッドＢ上において使用者にあった好適な体圧分散がもたらされ、寝姿勢の保持が図られる。
【００２１】
また、前記敷物１と通常の布団５とをカバー部材４により被覆すれば、和室における布団５をその使用者の好みに応じた固さとすることができる（図４参照）。なお、分割片２ａ〜２ｅは、表地３内に納めた際、互いに傾斜面ＳＬａ〜ＳＬｅを介して接触しているので、ずれにくく安定性があり、使用者にあった好適な体圧分散がもたらされ、快適な寝心地を得ることができる。
【００２２】
さらに、その敷物１に比較して硬質の素材で構成した下層部材６と、敷物１に比較して薄手且つ軟質の素材で構成した上層部材７との間に介在して、これら上層部材７と敷物１と下層部材６とをカバー部材４により被覆して使用することもできる（図５参照）。
その際、使用者が上層部材７に乗っても、下層部材６によって衝撃が吸収され、互いに傾斜面ＳＬａ〜ＳＬｅを介して接触している分割片２ａ〜２ｅで構成した、ずれにくく安定性のある前記敷物１によって体圧が好適に分散され、寝姿勢保持が図られる。
【００２３】
なお、表地３には、伸縮性を有する布地を用いることにより、分割片２ａ〜２ｅを弛みなく保持することができ、伸縮性と共に、撥水性、または防水性を有する布地を用いれば、表地３内に収容した前記分割片２ａ〜２ｅに、外部からの水分、汚れ等が侵入するのを遮断して、感染予防に寄与することができ、且つ清拭等、清掃も容易である。
【００２４】
また本発明にかかる敷物１では、分割片２ａ〜２ｅには、同様な反発性の軟質性素材で構成したものと、機械的加工を施して反発性を相違させた構成のものとを備え、それぞれ選択的に前記表地３内に交換収容して、敷物１として全体的、または要部の反発性を調整可能とすることもできる（図示省略）。
この場合、機械的加工としては、例えばプロファイル加工、プレス打ち抜き、くり抜き、熱プレス加工等を挙げることができる。

In addition, since the divided pieces 2a to 2e are in contact with each other via the inclined surfaces SLa to SLe when they are placed in the outer material 3, they are hardly displaced and have stability, and a suitable body pressure distribution suitable for the user is achieved. And a comfortable sleep.
[0022]
Further, the lower member 6 made of a material harder than the rug 1 and the upper member 7 made of a material thinner and softer than the rug 1 are interposed between the lower member 6 and the upper member 7. The rug 1 and the lower layer member 6 can be used by being covered with the cover member 4 (see FIG. 5).
In this case, even if the user rides on the upper layer member 7, the lower layer member 6 absorbs the impact, and the divided pieces 2a to 2e are in contact with each other via the inclined surfaces SLa to SLe. The body pressure is appropriately dispersed by the certain rug 1, and the sleeping posture is maintained.
[0023]
Note that, by using a stretchable fabric as the outer material 3, the divided pieces 2a to 2e can be held without slack, and if a fabric having elasticity and water repellency or waterproofness is used, the outer fabric 3 can be used. It prevents water, dirt, and the like from entering the divided pieces 2a to 2e housed therein, thereby contributing to prevention of infection, and is easy to clean such as wiping.
[0024]
Further, in the rug 1 according to the present invention, the divided pieces 2a to 2e are provided with one having the same resilience of a soft material and one having a different resilience by mechanical processing. Each of them can be selectively exchanged and accommodated in the outer material 3, so that the resilience of the rug 1 as a whole or the main part can be adjusted (not shown).
