Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an improved leg circumference measuring tool for lower limb deep vein thrombosis. Background Art

[0002] In recent years, the incidence of DVT in the Asian population has been increasing, so early detection, identification of these people, and better care are particularly important. Deep vein thrombosis (DVT) of the lower extremities is the most serious complication after varicose vein surgery of the lower extremities. Once DVT occurs, it will lead to post-thrombotic syndrome and affect the patient's work and quality of life. In severe cases, pulmonary embolism (PE) may even occur due to thrombus detachment. High-risk groups for deep vein thrombosis of the lower extremities: people with damaged blood vessel walls, blood stasis, and changes in blood components are prone to deep vein thrombosis of the lower extremities. Specifically, there are the following situations, patients who are bedridden for a long time.

[0003] Known Chinese publicly authorized utility model: (publication number: CN209712913U) discloses a heart-shaped leg circumference measuring instrument for preventing deep vein thrombosis of the lower limbs, including a skin contact belt, an upper tape measure storage box, a lower tape measure storage box, a handle, a rotating fixed shaft, a tape measure A and a tape measure B. The upper tape measure storage box is the same as the lower tape measure storage box and both are semi-heart-shaped structures. The lower ends of the upper tape measure storage box and the upper ends of the lower tape measure storage box are hinged to the rotating fixed shaft, and a handle is provided at the middle position of the rotating fixed shaft. The utility model has a simple structure, low manufacturing cost, easy use, quick and accurate measurement, easy to carry, and does not take up space. The length of tape measure B is 10 cm and 15 cm, and there is no need to measure the upper and lower heights of the patella. The leg circumference is measured by tape measure A at the corresponding height of tape measure B. As an auxiliary tool for preventing DVT, the presence of DVT can be discovered earlier and more timely, thereby reducing the occurrence of pulmonary embolism, saving patients, and improving the quality of life.

[0004] Venous thromboembolism refers to the formation of blood plaques in veins, which is most common in the deep veins of the lower limbs and is called deep vein thrombosis. Lower limb swelling is one of the most important and common symptoms of deep vein thrombosis. Changes in the circumference of the swollen affected limb can reflect the improvement of venous blood flow. At present, the routine clinical measurement of the leg circumference of patients with venous thromboembolism is to use a plastic tape measure to measure 15 cm above the upper edge of the patella and 10 cm below the lower edge of the left and right thighs, and obtain 4 data. Compare the upper left and upper right, lower left and lower right, respectively. The difference greater than 1 cm is clinically significant. It is necessary to make a mark 15 cm above the upper edge and 10 cm below the lower edge of the patella, and then measure the circumference at the mark. The action is repeated, the measurement time is long, and the tape measure cannot be guaranteed to be in the same cross section during measurement, which affects the accuracy of the data. The daily measurement personnel are inconsistent, resulting in errors in the results, increasing the workload of nursing and reducing work efficiency. Therefore, an improved leg circumference measurement tool for deep vein thrombosis of the lower limbs is proposed. Therefore, an improved leg circumference measurement tool for deep vein thrombosis of the lower limbs is proposed. Utility Model Content
