Apparatus for measurement of a limb circumference, a device for measurement of a limb compliance comprising the same and a device used in the treatment of lymphedema comprising the same

An apparatus for measurement of a limb circumference, comprising:

• a pull string module, comprising a surrounding component, wherein the surrounding component comprises an encircling part disposed around a limb of an individual, wherein the surrounding component is a measurement wire;
• a first measurement module disposed at the pull string module, and wherein the first measurement module is used to move along a longitudinal axis of the limb and meanwhile measure a length of the limb;
• a second measurement module disposed at the pull string module, and the second measurement module is used to measure a length of the encircling part simultaneously when the first measurement module move along the limb, so as to determine the limb circumference;
• at least one guide block which is disposed on the measurement wire;
• and
• a second connecting rod module, wherein the at least one guide block is disposed at the second connecting rod module, so as the at least one guide block is alongside a surface of the limb.
