In clinical diagnosis and treatment practice, measurement of the circumference of four limbs, particularly the circumference of the legs of the lower limbs, is an important measurement index in the process of conservative treatment of a plurality of diseases (conservative treatment of femoral neck fracture, intertrochanteric fracture and the like), perioperative period (knee joint replacement, patellar fracture reduction fixation, tibial plateau fracture reduction fixation and the like) or treatment of internal diseases (heart failure, renal failure and the like), and has great significance for early discovery and monitoring of the progression of diseases such as deep venous thrombosis of the lower limbs, heart failure, renal failure and the like.
The current method commonly used in clinic is to use a flexible rule for measurement. For example, when measuring the lower limb, the measurer uses the flexible rule to wrap the lower limb by one hand at a position 15cm above the patella and at a position 10cm below the patella, fits the flexible rule to the skin, and reads the measurement value.
The existing method for measuring the circumference of the lower limb and the leg by using a flexible rule by bare hands has the following defects:
first, when the flexible rule is placed by bare hands to surround the lower limb for one circle, the width of the flexible rule is narrow, the circumference of the cross section of the lower limb is difficult to ensure when the measurement is carried out, the circumference of the inclined plane of the lower limb is easy to cause the measurement actually due to the placing of the inclined plane, the measured value is larger than the true value, the repeatability of the multiple measurement is low, the comparability is poor, the early detection of the change of the circumference of the lower limb and the leg is not facilitated, and the diagnosis and the treatment of diseases are delayed.
Secondly, because of elasticity of muscles and skin of the lower limbs, when the flexible ruler is placed by hands to surround the lower limbs for one week, the degree of tightness between the flexible ruler and the lower limbs can be judged only by experience, and the degree of tightness between the flexible ruler is different due to the difference of force exertion of personal manipulations, so that measurement errors occur, and the flexible ruler is not beneficial to early detection of the change of the leg circumference of the lower limbs and delay diagnosis and treatment of diseases.

Advantageous effects
Compared with the prior art, the invention has the beneficial effects that:
when the limb circumference measurer is used for measuring the leg circumference, the measurement error caused by the deflection of the common flexible rule during the leg circumference measurement is reduced through the leg circumference measuring scale with larger width (5 cm). Simultaneously, through the design of fretwork round hole on the dipperstick, when tightening, let skin intrude round hole and surface parallel and level to accomplish even different measurers, when measuring different patients, or same patient's different limbs swelling degree, also possible elasticity is unanimous, accurately measure the diameter of week of limbs, reduced the measuring error that the difference of the degree of hugging of tape and skin leads to when measuring, convenient operation, the practicality is high.
