A limb circumference detection device includes a wire-pulling module, a first measurement module, and a second measurement module. The wire-pulling module is disposed around the limb in a surrounding manner. The first measurement module is arranged on the wire-pulling module, and the second measurement module is connected to the wire-pulling module. The first measurement module moves along the long axis direction of the limb and simultaneously measures the length of the limb. When the second measurement module moves along the long axis direction of the limb, the first measurement module synchronously measures the length of the wire-pulling module surrounding the limb, thereby continuously detecting the correlation between the limb length and the circumference. Two sets or even more than two sets of the wire-pulling modules of the detection device can be used in parallel. When two sets of wire-pulling modules are used in parallel, they can be used to monitor the change in limb softness, that is, compliance. When multiple sets of wire-pulling modules are used in parallel, they can be used for the treatment of limb edema.
