PROBLEM TO BE SOLVED: To provide blood pressure measurement cuff tube which can decrease deviation of blockages through folding directions though the blockages are generated or not generated according to the direction of the folded tube, and can prevent the blockage of the tube regardless of the direction of the folded tube.SOLUTION: The tube is shaped in a hollow long shape and has a plurality of projections 135 which project to the center side of a regular polygon, corresponding to each apex of the regular polygon RHX having five or more corners and inscribing the outer periphery of a cross section in the inner periphery shape of the cross section perpendicular to the longer direction.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】チューブが折り曲げられる方向によって閉塞の有無が生じるといった、折り曲げ方向による閉塞の片寄りを低減し、折り曲げられる方向によらずにチューブの閉塞を防止可能な血圧測定用カフチューブを提供する。【解決手段】中空の長尺形状を有し、長手方向に対し垂直な断面の内周の形状において、当該断面の外周に内接する、角数が5以上の正多角形RHXの各頂点に対応して、当該正多角形の中心側に突出する複数の突出部135を有する。【選択図】図4
