Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a supine leg circumference measuring device. Background Art

[0002] Deep vein thrombosis of the lower extremities usually causes varying degrees of lower extremity swelling. To determine whether the lower extremity swelling caused by deep vein thrombosis of the lower extremities has improved, daily fixed-point detection of leg circumference is an important indicator. The usual method is to use a soft tape measure to measure the thigh and calf circumference of the patient 10-15 cm above and below the knee joint every day and record it. The lower extremity swelling is determined by comparing the leg circumference data measured every day. The specific measurement position of each patient is determined by the medical staff according to the individual differences of the patient. Now in the actual measurement process, the doctor The caregiver will first find a reference point at the patella of the knee joint and mark it with a marker, then use the marked point as the reference point, measure 10-15cm along the thigh or calf to determine the measurement position of the leg circumference, and mark it. The next time the leg circumference is measured, you only need to find the position of the marked point or marked line. However, in actual daily life, the marked point or marked line is very easy to be lost due to sweating or bathing, and the reference point needs to be found again, which will easily lead to measurement errors. At the same time, the marked point or marked line on the patient's leg is not beautiful.

[0003] The Chinese utility model patent CN213371980U announced on June 8, 2021 discloses a leg circumference measuring device specifically for deep vein thrombosis of the lower extremities, including a knee positioning belt, two rulers, a thigh leg circumference measuring device, and a calf leg circumference measuring device. This utility model still has shortcomings: if the leg circumference is measured in a standing position, the patient's legs are prone to shaking and twisting, resulting in inaccurate measurement results; if the leg circumference is measured in a supine position, the leg circumference measuring device does not have a cushion under the leg to insulate heat. The table / ground is cold in cold weather, and the patient's legs will get cold and feel uncomfortable when placed on the table / ground. Moreover, the leg circumference measuring device has a weak fixation on the legs, and the patient's legs are prone to flip to both sides, resulting in inaccurate measurement results.

The two leg pads 23 are respectively arranged at the calf end 21 and the thigh end 22 of the positioning plate 2. An extension plate 24 is connected between the positioning plate 2 and the leg pad 23. The extension plates 24 at both ends of the positioning plate 2 make the two leg pads 23 in the same straight line and fixed in position. A leg hoop 3 that can undergo elastic deformation is arranged on the positioning plate 2. The knee joint of the human leg is clamped in the clamping mouth of the leg hoop 3. The human calf is placed on the leg pad 23 at the calf end 21, and the human thigh is placed on the leg pad 23 at the thigh end 22, so that the human foot is suspended in the air. The two leg pads 23 are both provided with a tape measure 1 for measuring leg circumference on the side, and the tape measure 1 is provided with a tape outlet 10 on one side near the leg pad 23, and the tape 11 of the tape measure 1 extends from the tape outlet 10. When measuring, the tape 11 of the calf end 21 of the tape measure 1 is wrapped around the outer circumference of the human calf, and the tape 11 of the thigh end 22 of the tape measure 1 is wrapped around the outer circumference of the human thigh. When measuring, the medical staff puts the supine leg circumference measuring device horizontally on the table / ground, clamps the patient's knee joint position in the clamping mouth of the leg cuff 3, and places the patient's thigh and calf on the two leg pads 23 respectively, and then uses two tape measures 1 to measure the patient's thigh and calf respectively.
