Abstract

This utility model relates to the field of medical devices, specifically to a leg circumference measuring ruler for lower extremity venous thrombosis. It solves the problems of existing devices being cumbersome to measure and potentially compressing the patient's leg, which could worsen the condition. This measuring ruler mainly consists of a knee fixation part, a limiting mechanism, an arc-shaped measuring clip, and a flexible measuring tape. The knee fixation part includes a positioning strap and a fixing component; the positioning strap is fixed around the knee via the fixing component, and a rotating shaft on one side connects to the limiting mechanism. The limiting mechanism consists of a housing and a measuring tape, which is snapped onto the rotating shaft to achieve 360° rotation and adjust the measurement position. An arc-shaped measuring clip is fixed to one end of the measuring tape, and flexible measuring tapes are attached to both ends of the arc-shaped measuring clip. The arc-shaped measuring clip moves the flexible measuring tape to fit against the patient's leg, completing a rapid measurement. The measurement process avoids compressing the patient's leg, and due to the simple structure of this device, it saves the physical exertion of medical staff.
