[0002] Clinically, patients with lower extremity venous thrombosis or edema need to measure their leg circumference regularly. The commonly used method for measuring leg circumference is to first determine the position of the patient's patella, then mark the upper and lower edges of the patella with a marker, and then use a tape measure to draw lines for measurement. This method of line measurement has the following problems: 1. During the entire measurement process, it is necessary to repeatedly draw lines with a marker and position them multiple times, which is cumbersome. 2. After the patient wipes his body or sweats, the marked line tends to fade or even disappear, and the marking line needs to be repositioned, which increases the workload of the nurses, and the lines on the legs also affect the appearance. 3. The measuring rulers and markers used in hospitals may be different in model specifications, which will affect the accuracy of the measurement results. Utility Model Content
