The present invention in a short period of time while a simple structure, simple, and hygienically can perform a series of operations such as diaper changing and clothing of attachment and detachment of the care recipients, caregivers labor burden and those who require care of the can be greatly reduced such as irritation and pain, also provides a diaper changing assistance instrument capable of enhancing the efficiency of the work to be inclined at mite bodily care recipient. A body M constituting the diaper changing assistance instrument of the rigid urethane can be formed integrally rich resilient hard in order to disperse the weight acting on the contact surface 1a2 points of the waist material and curved It will be the essential form of a material to maintain a smooth and strength, contact it with the protection it is desirable to use a material rich in light and elastic, the spine is located in the per top of height adjustment devices 1b Given that it is smooth, its three-dimensional shape is suitably combination of saddle shape, and oval. .BACKGROUND【課題】簡略な構造でありながら短時間で、簡単、かつ衛生的に要介護者のおむつ交換と衣類の着脱など一連の作業を行うことができ、介護者の労力の負担及び要介護者の苦痛と苛立ち等を大幅に軽減することができ、また、要介護者の身体を微力で傾斜させて作業の効率を高めることが可能なおむつ交換支援器具を提供する。【解決手段】おむつ交換支援器具を構成する本体Mは、腰部との接触面1a2点に加わる体重を分散させるためには硬質で弾力性に富んだ一体で形成できる硬質ウレタン系の素材と曲面の円滑と強度を保つ素材との形成が必要不可欠なことであるが、それは軽量かつ弾性に富んだ素材を使用することが望ましく、高さ調節器具1bの上部あたりに位置する背骨への保護と接触を滑らかにすることを考えると、その立体形状は鞍形状、且つ楕円型の組み合わせが適当である。【選択図】図1
