Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to an integrated leg circumference measuring device for diagnosing and treating deep vein thrombosis. Background Art

[0002] Deep vein thrombosis is a venous thrombosis caused by the stagnation and coagulation of venous blood, which leads to the formation of blood clots in the veins, causing venous reflux obstruction. Venous reflux obstruction further causes poor blood return to the limbs, causing more and more blood in the limbs, which will cause limb swelling. Limb swelling will cause the limb diameter to increase. Therefore, medical staff monitor the leg circumference and can see whether the patient's symptoms are getting worse or lighter. If the leg circumference is getting thicker, it means that the collateral circulation is not well established and the symptoms are gradually getting worse; if the leg circumference is getting thinner, it means that the collateral circulation is gradually established, the thrombolytic or thrombectomy treatment is ideal, and the blood return to the legs has been improved, so the leg circumference is gradually reduced.

[0003] Currently, when measuring leg circumference, three-point positioning is required before using a tape measure to measure the upper and lower leg circumferences. When measuring with a tape measure wrapped around the body, the upper leg circumference needs to be measured separately from the calf, which is inconvenient. When three-point positioning is used, positioning is also inconvenient. The upper leg circumference needs to be measured about 15 cm upward from the patella and about 10 cm downward from the lower leg circumference. Furthermore, when measuring with a tape measure wrapped around the body, positioning is prone to deviation, which affects the accuracy of the measurement. Utility Model Content
