Description
Technical Field
[0001] The utility model relates to the technical field of leg circumference measurement, in particular to a leg circumference measurer for VTE patients. Background Art
[0002] Venous thromboembolism (VTE) refers to the situation of blood plaque formation in veins, most commonly in the deep veins of the lower extremities, known as deep vein thrombosis. Venous thrombosis generally has no symptoms, and occasionally there will be pain and lower extremity edema. Some emboli will enter the lungs, leading to potentially fatal pulmonary embolism. Symptomatic venous thrombosis often leads to a series of complications. Clinically, for such patients, medical staff need to measure the leg circumference of their swollen lower extremities every day, and judge whether the patient's condition has improved through the change of leg circumference. The traditional method is that medical staff use a tape measure to measure the thigh circumference about 15 cm above the upper edge of the patient's patella and the calf circumference about 10 cm below the lower edge of the patient's patella, which is time-consuming and laborious, and prone to reading errors.
[0003] Therefore, there are a leg circumference measurer for VTE patients disclosed in the utility model patent with the application number 202123155596.7 and a new VTE leg circumference measuring tool disclosed in the utility model patent with the application number 202120289201.3, etc., which are used to measure the thigh circumference and calf circumference of patients.
[0004] However, it is found in the use process that when the existing leg circumference measurer is used, medical staff need to bend down or squat down to measure. Since there are a large number of patients in the hospital and medical staff need to measure repeatedly, it is also time-consuming and laborious, and prone to occupational diseases, resulting in poor practicability. Therefore, it is urgent to improve the existing equipment. Summary of the Utility Model
[0005] To solve the above technical problems, the utility model provides a hand-held support mechanism for medical staff to adjust the position of the measuring mechanism, and at the same time guide the measuring mechanism through the guiding mechanism, so that the measuring mechanism surrounds the patient's leg and measures the patient's leg circumference, thereby improving the practicability of the equipment, a leg circumference measurer for VTE patients.
[0006] A leg circumference measurer for VTE patients of the utility model includes a measuring mechanism; it also includes a support mechanism and a guiding mechanism, and the measuring mechanism and the guiding mechanism are both installed on the support mechanism;
[0007] The support mechanism adjusts the position of the measuring mechanism, the guiding mechanism guides the measuring mechanism, and the measuring mechanism measures the patient's leg circumference;

At the same time, the camera takes pictures of the measuring mechanism at the left end of the connecting tube, and the touch screen displays the captured pictures, which is convenient for medical staff to observe the patient's thigh circumference. Then, the first motor is turned on, and through the transmission of the first transmission, the connecting tube rotates, and then the measuring mechanism surrounds the patient's calf, and the above steps are repeated to enable medical staff to observe the patient's calf circumference, thereby improving the practicability of the device.
