[0002] When treating patients with lower limb venous thrombosis or edema, it is necessary to measure the patient's leg circumference. The general measurement steps are as follows: first, draw a line with the patient's patella as the center as the central axis; then draw a line along the leg 10 cm above and below the patella; then use a tape measure to measure the drawn line along the circumference to obtain the leg circumference data. In the process of drawing auxiliary lines, it is necessary to use a ruler to locate multiple times to determine the upper and lower leg circumference measurement points, and the positioning is relatively cumbersome.

[0004] Although ten centimeters above and below the patella is a commonly used method for measuring the patient's leg circumference, it is not the only standard. Usually, the specific method for measuring leg circumference will be determined based on medical needs and the specific circumstances of the measured object. For example, for patients with special wounds or surgical sites, it may be necessary to avoid these areas for leg circumference measurement to avoid causing unnecessary pressure or stimulation to the wound or surgical site. At this time, other appropriate measurement positions need to be selected. For example, for patients who need special attention to the situation of specific parts, such as patients with a higher risk of deep vein thrombosis (DVT) in the lower limbs, it may be necessary to select measurement points for leg circumference measurement to meet special medical requirements. Therefore, the measuring device in this comparative document has a limited scope of application and is not very flexible. Utility Model Content
