A flexible measuring element cooperated with a plurality of blood pressure measuring cuffs is disclosed. The flexible measuring element includes a flexible body, an identify mark distribution region and an assign portion. Wherein, the identify mark distribution region is disposed on the flexible body, and the identify mark distribution region has at least two different identify mark partition, and the at least two different identify mark partitions are corresponds to a plurality of identify mark on the blood pressure measuring cuffs. Wherein, when a user coil the flexible body at a limb of an animal, the assign portion is located on a specific identify mark distribution partition of the identify mark distribution partitions, so as to advise the user choose a specific blood pressure measuring cuff corresponding to the identify mark distribution partitions.本案係揭露一種可撓性量測元件,適以與複數量測血壓袖套作配套。該可撓性量測元件包括一撓體、一辨識標誌分佈區、一指示部。其中,該辨識標誌分佈區係設置於該撓體上,且該辨識標誌分佈區具有至少兩種不同的辨識標誌區塊,且該些辨識標誌區塊係與該些量測血壓袖套所標示的複數辨識標誌相互配套對應。其中,於一使用者以該撓體圍繞於一動物肢體時,該指示部係落於該些辨識標誌區塊中之一特定辨識標誌區塊,藉以示意該使用者選擇相對應於該特定辨識標誌區塊之一特定量測血壓袖套。1‧‧‧可撓性量測元件15‧‧‧指示部151‧‧‧孔縫19d~19g‧‧‧辨識標誌區塊6‧‧‧動物肢體
