The invention relates to a limb circumference detection device, which comprises a wire-pulling module, a first measuring module and a second measuring module. The wire-pulling module is disposed on the limb in a surrounding manner. The first measuring module is disposed on the wire-pulling module. The second measuring module is connected to the wire-pulling module. The first measuring module is movable along the longitudinal direction of the limb for measuring the limb length. When the second measuring module is moving along the longitudinal direction of the limb, the first measuring module is configured to simultaneously measure the length of the wire-pulling module around the limb, so as to continuously detect the correlation between the limb length and the circumference. The detection device of the present invention may be connected in parallel with two or more sets. When the detection devices are connected in parallel with two sets, the invention may be used for monitoring the variation of limb softness, i.e. compliance. While being connected in parallel with multiple sets, the invention may be used for treatment of limb edema.一種肢體周徑檢出裝置，包括拉線模組、第一量測模組以及第二量測模組。拉線模組環繞設置於肢體，第一量測模組設置在該拉線模組，第二量測模組連接該拉線模組，該第一量測模組沿該肢體長軸方向移動並同時量測該肢體長度。該第二量測模組沿該肢體長軸方向移動時，該第一量測模組同步量測該拉線模組環繞該肢體的長度，藉此連續檢測出肢體長度與周徑之間的關聯。本發明的檢出裝置可並聯兩組或甚至並聯兩組以上使用。本發明的檢出裝置在並聯兩組時可用於監測肢體軟硬度的變化，亦即順應性。本發明的檢出裝置在並聯多組時可用於肢體水腫之治療。
