Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a lower limb venous thrombosis measuring ruler. Background Art

[0002] Lower extremity venous thrombosis is a common peripheral vascular disease. Venous valve insufficiency and concurrent pulmonary embolism caused by lower extremity venous thrombosis are a major threat to the patient's labor and life safety. This disease has always been highly valued in clinical practice. The three major factors of venous thrombosis are blood stagnation, venous wall damage and hypercoagulable state. The left lower extremity thrombosis is much higher than the right lower extremity, especially primary iliac-femoral vein thrombosis. Sometimes lower extremity venous thrombosis can also extend centripetally to the inferior vena cava, and even block the renal vein, causing renal failure and threatening life.

[0003] Deep vein thrombosis in the lower limbs may cause swelling of one side of the limb. The greatest risk of thrombus is that it may break off and form fatal pulmonary embolism. Therefore, leg circumference is often measured clinically to observe whether thrombosis is likely to occur. Clinically, the circumference of lower limb venous thrombosis is usually measured using a measuring ruler, which generally includes an upper measuring ruler, a lower measuring ruler and a telescopic ruler. When measuring, use the upper measuring ruler to measure the circumference of the thigh, the lower measuring ruler to measure the circumference of the calf, and then use the telescopic ruler to read the distance between the thigh and the calf.

[0004] The above measurement method requires the use of a measuring ruler to mark the midpoint and both sides of the patella, and then mark the periphery of the thigh and the calf along the midpoint of the patella according to the measuring ruler. The operation steps are cumbersome and deviations are prone to occur during the measurement process. For this reason, we propose a lower extremity venous thrombosis measuring ruler.

The entire material of the measuring ruler adopts a soft plastic support, which is convenient for disinfection during the measurement process.

[0016] The scale on the back of this main ruler can be used to measure the length range of the patella, so as to confirm the midpoint. After aligning the midpoint with the midpoint line, the partition groove on the top surface of the main ruler can be used to divide the thigh range into 15 cm and the calf range into 10 cm, which is convenient for subsequent measurement and positioning.

[0017] By adding a spare fixing belt to fill the area that the fixing belt does not cover, the belt is connected to the measuring tape through the buttons at both ends of the belt body, and the belt bodies are arranged with eight centimeters between them. This can accommodate patients with various thigh sizes, ensure the circular measurement distance between the two sets of measuring tapes, and assist in maintaining stability during the measurement process, thereby improving the scope of applicability.

[0029] The utility model provides Figure 1-5 A lower extremity venous thrombosis measuring ruler shown includes a main support ruler 1, a measuring tape 2 is provided at the top and bottom of the main support ruler 1, and a spare fixing belt 3 is connected to one side of the measuring tape 2, the main support ruler 1 includes a main ruler 101, and a midpoint line 102 is provided on the front of the main ruler 101, partition grooves 103 are provided on both sides of the midpoint line 102, and a tape 201 is attached to the top and bottom of the main ruler 101;

[0030] In order to locate the midpoint of the patella more accurately, Figure 1-2 As shown, the scale on the back of the main ruler 101 can be used to measure the length range of the patella, so as to confirm the midpoint. After aligning the midpoint with the midpoint line 102, the partition groove 103 on the top surface of the main ruler 101 can be used to divide the thigh range into fifteen centimeters and the calf range into ten centimeters, which is convenient for subsequent measurement and positioning.

[0031] like Figure 1-4 As shown, the measuring tape 2 includes a tape measure 201, and one end of the tape measure 201 is connected to a metal buckle 202, one side of the tape measure 201 is connected to a fixing belt 203, and the other end of the tape measure 201 is connected to a winding box 204, one side of the winding box 204 is connected to a knob 205, and the other side of the winding box 204 is provided with a snap ring groove 206, and the inner wall of the snap ring groove 206 is attached with a magnetic attraction layer 207;

[0032] In order to further improve the convenience of the measurement steps, Figure 1-4As shown, this measuring ruler measures the measuring range of both ends of the main ruler 101 by two sets of tape measures 201. The two sets of tape measures 201 with a width of two centimeters can respectively surround the thigh and calf ranges to perform the measurement process without drawing lines. The metal buckle 202 at the front end of each set of tape measures 201 can position the surrounding tape measures 201, which is convenient for stable detection. In order to keep the spacing between the two sets of tape measures 201 stable during the process, the fixing belt 203 arranged and connected between the spacings is used to maintain the measurement accuracy, so that the tape measures 201 can be connected to each other without drawing lines. Combined with the main ruler 101, a quick measurement process with no deviation and accuracy is formed, ensuring the consistency of daily measurement and improving measurement efficiency. The entire material of this measuring ruler adopts a soft plastic support, which is convenient for disinfection during the measurement process.
