    • PROBLEM TO BE SOLVED: To provide an overlay mattress formed so as to be adapted to criterion for evaluation of countermeasure against bed sore. SOLUTION: The overlay mattress is formed with a plurality of unit members 1a, 1b, 1c placed on a basic mattress 2 through fitting means 3. These unit members 1a-1c are formed by covering a soft material 4 having a thickness within a prescribed range with a waterproof face cloth 5 combinedly having stretchability. As the soft material 4, is adopted, for example, a urethane foam material having a density of 45 kg/m 3 , an apparent density of 10 kg/m 3 -100 kg/m 3 and a compression hardness of 10 N-400 N, which is an expandable material having a thickness of 30 mm-70 mm. A soft material 4 different in resilience may be adopted as a unit member, on which back and waist parts of a user are put, among the unit members 1a-1c. As a means for changing the resilience of the soft material 4, a mechanical processing for adjusting the resilience may be conducted. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:提供形成的覆盖床垫,以适应用于评价针对床疮的对策的标准。

      解决方案:覆盖床垫通过装配装置3形成有放置在基本床垫2上的多个单元构件1a,1b,1c。这些单元构件1a-1c通过覆盖厚度在内的软质材料4而形成 具有防水面布5的规定范围,其具有拉伸性。 作为软质材料4,例如可以使用密度为45kg / m 3,SP表观密度为10kg / m 3的聚氨酯泡沫材料, 100kg / m 3< SP>和10N-400N的压缩硬度,其为厚度为30mm-70mm的可膨胀材料。 在单元构件1a-1c中,可以采用弹性不同的柔软材料4作为用户的背部和腰部放置在其上的单元构件。 作为用于改变柔软材料4的弹性的手段,可以进行用于调节弹性的机械处理。 版权所有(C)2004,JPO
