< Topic >Troublesome of installation of the lead line with the electrocardiogram induction cable which can prevent the installation mistake is offered.SolutionsIn the cable where in order to measure the electrocardiogram of canonical 12 induction, in each case the end face is jointed by the connector electrically, to the relay section is bundled in one, branching from the relay section, being the lead line where you can install the terminal in the Tip, has lead line R, are installed in the dextral legs lead line N, the lead line L which is installed in the limb with respect to the left and is installed in the left legs the lead line F which you install in the limb with respect to dextral at least, as for lead line R and lead line L is briefer than lead line N and lead line F, length of one side of lead line R and lead line L150 - 250mm, other length with 750 - 850mm, it features that each difference of difference of length of lead line R and length of lead line N, and length of lead line L and length of lead line F is 450 - 550mm.< Choice figure >Drawing 3【課題】リード線の装着の煩雑さと装着間違いを防ぐことができる心電図誘導ケーブルを提供する。【解決手段】標準12誘導の心電図を測定するために、いずれも基端がコネクタに電気的に接続され、中継部まで一つに束ねられ、中継部より分岐して先端に端子が取り付けられたリード線であって、右上肢に装着するリード線R、右下肢に装着するリード線N、左上肢に装着するリード線L及び左下肢に装着するリード線Fを少なくとも備え、リード線R及びリード線Lはリード線N及びリード線Fよりも短いケーブルにおいて、リード線R及びリード線Lの一方の長さが150~250mm、他方の長さが750~850mmで、リード線Rの長さとリード線Nの長さの差、及びリード線Lの長さとリード線Fの長さの差がいずれも450~550mmであることを特徴とする。【選択図】図3
