Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, in particular to a device for measuring the circumference of edematous lower limbs. Background Art

[0002] When measuring the circumference of edematous lower limbs, it is necessary to measure the leg circumference. Generally, the thigh circumference at 15 cm above the patella of both lower limbs and the circumference at 10 cm below the patella or the thickest part of the calf muscle belly are measured. The traditional medical measurement method generally uses a tape measure to measure the circumference of both legs, which requires repeated fixed-point measurements and many steps. It is easy to cause large errors in the measurement data, and the operation is time-consuming and labor-intensive, which affects the medical staff's observation of the patient's condition changes. Therefore, we designed a device that is convenient for measuring the circumference of edematous lower limbs. Utility Model Content
