Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a measuring tool for lower limb deep vein thrombosis. Background Art
[0002] Deep vein thrombosis is a venous reflux disorder caused by abnormal coagulation of blood in the deep veins. It often occurs in the lower limbs, and swelling of the lower limbs is the main or only symptom. Therefore, medical staff need to measure the limb circumference of the patient 15 cm above the patella and 10 cm below the patella. The current measurement method is that medical staff use a soft ruler to measure the circumference of the swollen area and record the data.
[0003] For example, the publication number: CN218651807U discloses a measuring tool for deep vein thrombosis of lower extremities, including: a telescopic rod, a first vertical rod, a second vertical rod, a cross bar, and a tape measure; the upper end of the telescopic rod is connected to one end of the cross bar; the other end of the cross bar is the lower end of the first vertical rod and the upper end of the second vertical rod; the upper end of the first vertical rod is connected to a tape measure; the lower end of the second vertical rod is connected to a tape measure. Except for the tape measure, the present application uses rigid materials in its entirety, so each time a measurement is made, it is only necessary to adjust the cross bar to the same height through the telescopic rod, and the measurement data for the same patient each time is the measurement data of the same position, and no error will be caused by the deviation of the measurement position each time. At the same time, the tape measure uses a belt, which is not easy to deform in its width direction, so as to avoid the bending and tilting of the ordinary tape measure when surrounding the patient's lower limbs, resulting in measurement errors.
[0004] In the above patent, the horizontal bar is adjusted to the same height by the telescopic rod, so that the measurement data of the same patient each time is the measurement data of the same position. However, the patella is in a protruding state compared with the leg muscles, which makes it easy for the skin in the measuring area to not contact with the zero point of the tape measure, resulting in measurement errors. Therefore, a measuring tool for deep vein thrombosis of the lower limbs is needed, so that the zero point of the tape measure can directly contact the skin at the measuring area when the measuring tool is measuring, thereby reducing measurement errors. Utility Model Content
[0005] To this end, the utility model provides a measuring tool for deep vein thrombosis of the lower limbs, which solves the problem that the patella is in a protruding state compared with the leg muscles, which easily makes the skin in the measuring area not contact with the zero point of the tape measure, resulting in measurement errors through a measuring compensation mechanism.
