< Topic >It is used as one of evaluation of the kidney functional degree of serious illness the eGFRcys value which is calculated from age and serum sister chin C value by GFR prediction expression, offer of the scale which is required easily.SolutionsVaginate it is not, inside, the fixed shaku 2 which possesses postscript slide shaku and among those, the slide shaku 8 which left and right unrestrictedly moves it becomes bone-dry. In fixed shaku, it possesses two aperture windows in the top and bottom, in the upper part the window 3, forms the window 4 in the lower part, age graduation 5, eGFRcys value reading arrow 6 for the man, it displays the eGFRcys value reading arrow 7 for the woman in the upper edge of the window 4 alongside the upper edge of the window 3. In the part which in slide shaku 8 is exposed from the window 3 of fixed shaku 2, eGFRcys graduation 10 is displayed in the part which exposes sister chin C graduation 9, from the window 4 alongside the window upper edge, alongside the window upper edge.< Choice figure >Drawing 1【課題】腎臓機能の重症度の評価の一つとして使われる、年齢と血清シスタチンC値からGFR推算式により算出されるeGFRcys値が、容易に求められるスケールの提供。【解決手段】鞘状をなし、内部に、後記滑り尺を有する固定尺2とその中を、左右自在に動く滑り尺8からからなる。固定尺には、上下に2つの開口窓を有し、上方に窓3、下方に窓4を形成し、窓3の上縁に沿って年齢目盛り5を、窓4の上縁に男性用eGFRcys値読み取り矢印6、女性用eGFRcys値読み取り矢印7を表示する。滑り尺8に固定尺2の窓3から露出する部分に、窓上縁に沿って、シスタチンC目盛り9を、窓4から露出する部分に、窓上縁に沿ってeGFRcys目盛り10を表示する。【選択図】図1
