Description

technical field [0001] The invention specifically relates to a portable electronic measuring ruler for limb edema volume. Background technique [0002] There are many causes of limb edema, which can be divided into physiological edema and pathological edema from the cause of the disease. At present, there are few researches on the measurement methods of limb edema volume in China, mainly including water replacement method, Perometer measurement method, bioelectrical impedance Spectral measurement method (Bioimpedance) and arm circumference measurement method three measurement methods. [0003] The water replacement method is the gold standard for measuring lymphedema. There are two methods for the water replacement method. One is to put a certain amount of water in a steel drum of a specific size, and then put the limbs into the bucket for a certain length, and change according to the height of the water surface. Calculate the volume of the limb. The other is to fill the c...
