Description

Technical Field

[0001] The utility model belongs to the technical field of measurement, and in particular relates to a leg circumference measuring device. Background Art

[0002] VTE refers to venous thromboembolism, which mainly refers to abnormal coagulation of blood in the venous lumen, leading to obstruction of the deep vein lumen, resulting in venous reflux disorder. Deep vein thrombosis in the lower extremities can cause swelling of one side of the limb. The biggest risk of thrombus is that it may break off and form fatal pulmonary embolism, so leg circumference is often measured clinically to observe the possibility of thrombosis.

[0003] The VTE measurement of leg circumference is generally recommended to measure the thigh circumference 15cm above the patella of both lower limbs and the circumference 10cm below the patella or at the thickest part of the calf muscle belly. The correct measurement position can provide accurate data to help medical staff assess the patient's condition and risk level.

[0004] At present, the measurement of both lower limbs is to measure the midline position of the patient's patella by a tape measure, and then measure the position of the calf and thigh accordingly, and use a marker to mark the corresponding position of the tape measure. Four measurements are required at one time, and the operation process is relatively cumbersome, and the other leg is measured after measuring one leg. The existing patent number is CN219048496U, a leg circumference measuring ruler, including a main ruler, a first and a second measuring ruler, and a binding belt, etc., the "0" scale position of the main ruler can be directly aligned with the midpoint of the patella, fixed by a binding belt, and then the upper and lower ends are directly measured, and the thigh and calf circumference are measured twice respectively. The operation is simple, and one side can be installed to measure the limbs on one side. However, the device needs to be measured twice to obtain the thickness of the thigh and calf of both lower limbs, and the midline position of the patella needs to be determined first before the binding belt can be connected to the patient's body. After each measurement, the recorded data needs to be read out, and the difference calculation must be performed through calculation to obtain a reliable conclusion. Utility Model Content

Then, the measuring belt 301 can be pulled for use, and the other end of the measuring belt 301 is aligned with the zero scale line segment to read the data.

[0047] In this embodiment, a second fixing device is also provided in the mounting hole, and the second fixing device includes a partition 203, and the partition 203 and the adhesive plate 201 form a first fixing channel 202 for fixing the measuring tape 301, and the partition 203 is detachably connected with a clamping plate 207, and the contact between the clamping plate 207 and the partition 203 is a slope structure, and the clamping plate 207 and the partition 203 form a second fixing channel 204 for fixing the measuring tape 301.

[0048] One end of the measuring tape 301 with the zero scale line passes through the first fixed channel 202 and is fixed by the first fixed channel 202. The other end of the measuring tape 301 is then wrapped around to form a ring structure for measuring the patient's lower limbs, and passes through the second fixed channel 204 formed by the splint 207 and the partition 203.
