Description

Technical Field

[0001] This utility model relates to the field of medical measuring instrument technology, and in particular to a leg circumference measuring ruler for lower extremity venous thrombosis. Background Technology

[0002] In the medical field, deep vein thrombosis (DVT) of the lower extremities is a common condition. Its treatment and management require accurate measurement of the patient's leg circumference to ensure timely detection of changes in the condition and to take appropriate treatment measures. Specifically, the leg circumference is measured at points 15 cm above and 10 cm below the center of the patella. Accurate leg circumference measurement is crucial for patients with DVT of the lower extremities, as it helps improve the success rate of treatment and reduce the risk of complications.

[0003] In the traditional process of measuring leg circumference in lower extremity deep vein thrombosis, a soft ruler or tape measure is usually used for manual measurement. Although this method is relatively simple to operate, its disadvantage is that it is easily affected by human factors, which can lead to certain errors in the measurement results. In addition, the manual measurement process itself is quite tedious, especially when drawing the auxiliary measurement line segment at the center of the patella, which requires a series of calculations. This is not only time-consuming, but also not conducive to quickly and accurately obtaining the patient's leg circumference data. The inaccuracy and time-consuming nature of this measurement method not only increases the workload of medical staff, but also affects the patient's treatment efficiency to some extent. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing technology has the disadvantage of the patellar distance measurement position being unfavorable. To address this, we propose a leg circumference measurement ruler for lower extremity venous thrombosis.

[0005] To achieve the above objectives, this application adopts the following technical solution: a leg circumference measuring ruler for lower extremity venous thrombosis, comprising a frame, with Velcro straps fixedly connected to both ends of the frame, two long rods fixedly connected inside the frame, three sliding plates slidably connected to the surfaces of the long rods, a measuring tape fixedly connected to one end of two of the sliding plates, a sliding rod fixedly connected inside the middle sliding plate, a slider slidably connected to the surface of the sliding rod, a housing slidably connected to the surface of the sliding plate, two ends of the top of the slider slidably connected to the sides of the housing, a marker pen fixedly connected to the bottom of the housing, a toothed plate fixedly connected to the bottom of the housing, and two long plates of different lengths arranged between the three sliding plates.

[0006] Preferably, an anti-slip groove is provided on one side of the frame, and an extension plate is fixedly connected to one side of the middle slide plate. One end of the extension plate is threadedly connected to a pressing rod, and one end of the pressing rod abuts against the inside of the anti-slip groove.

[0007] Preferably, a spring is fixedly connected to the bottom of the slider, and the bottom of the spring is fixedly connected to the inner wall of the housing.

[0008] Preferably, both ends of the long plate are T-shaped structures, and T-shaped slot blocks are inserted into both ends of the long plate. One side of the T-shaped slot block is fixedly connected to the slide plate.

[0009] Preferably, a metal sheet is fixedly connected to the surface of the measuring tape. The metal sheet is made of stainless steel and has shape memory properties.

[0010] Preferably, the dimensions of the toothed plate surface are a central axis symmetrical figure, and the marker is placed on the central axis of the toothed plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, by setting measuring tapes at both ends of the patella's center point, after the marker pen draws the patella's center line, the two measuring tapes can be aligned with the upper and lower measurement areas of the patella, ensuring the accuracy of the measuring tapes' position relative to the patella's midpoint line, which is more conducive to measuring the leg circumference of patients with venous thrombosis in clinical applications.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: a leg circumference measuring ruler for lower extremity venous thrombosis, including a frame 1, with Velcro straps 2 fixedly connected to both ends of the frame 1, two long rods 3 fixedly connected inside the frame 1, three slide plates 4 slidably connected to the surface of the long rods 3, a measuring tape 5 fixedly connected to one end of each of the two slide plates 4, a sliding rod 6 fixedly connected inside the middle slide plate 4, a slider 7 slidably connected to the surface of the sliding rod 6, a housing 8 slidably connected to the surface of the slide plate 4, the top two ends of the slider 7 slidably connected to the sides of the housing 8, a marker pen 9 fixedly connected to the bottom of the housing 8, and the bottom of the housing 8 fixedly... A toothed plate 10 is fixedly connected, and two long plates 15 of different lengths are set between the three sliding plates 4. A medical staff member places a Velcro strap 2 on the patient's leg, positioning the frame 1 to one side of the patient's leg. The user pushes the sliding plate 4 along the long rod 3 to the patient's knee, then presses down on the housing 8, sliding it downwards along the slider 7 to bring the marker pen 9 close to the upper edge of the patient's patella. The housing 8 is then pushed, causing the slider 7 to slide along the slide rod 6, allowing the marker pen 9 to draw a straight line at the upper edge of the patella. A straight line is then drawn at the lower edge of the patella using the same method. Finally, the toothed plate 10 is used to measure the upper and lower edges of the patella. The center point between segments is determined, and a straight line is drawn using marker 9 to obtain the midpoint line of the patient's patella. Marker 9 is precisely aligned perpendicularly to the midpoint line with the housing 8. The design of two long boards 15 of different lengths restricts the distance between the three sliding plates 4. The left long board 15 ensures that the distance between the left measuring tape 5 and the midpoint line drawn by marker 9 is 15cm, and the right long board 15 ensures that the distance between the right measuring tape 5 and the midpoint line is 10cm. The two measuring tapes 5 are positioned at 15cm and 10cm from the center point of the patient's patella, respectively. Finally, medical personnel wrap the measuring tapes 5 around the patient's leg. The device reads data and obtains the required measurement results. The combination of frame 1 and Velcro 2 ensures the stability of the device after it is worn, preventing displacement between the patient's leg and the device during the measurement process. At the same time, frame 1 restricts the patient's leg to keep it in a straight position, preventing the patient's leg from bending and affecting the measurement accuracy. During the process, after obtaining the midpoint line of the patient's patella through the marker pen 9, the distance between the upper and lower parts of the patella and the leg is directly restricted by the long plate 15, ensuring the accuracy of the measurement position of the two measuring tapes 5 relative to the midpoint line of the patella, which is more conducive to measuring the leg circumference of patients with venous thrombosis in clinical applications.

[0020] Reference Figure 1 , Figure 2 and Figure 4As shown in this embodiment: an anti-slip groove 11 is provided on one side of the frame 1, and an extension plate 12 is fixedly connected to one side of the middle slide plate 4. One end of the extension plate 12 is threadedly connected to a compression rod 13. One end of the compression rod 13 abuts against the inside of the anti-slip groove 11. When medical personnel use a marker pen 9 to confirm the position of the patient's patella at the upper, middle and lower points, the compression rod 13 is threadedly connected to the extension plate 12, and then the compression rod 13 is screwed into the anti-slip groove 11. The compression rod 13 is pressed tightly against the inner wall of the anti-slip groove 11, fixing the position of the middle slide plate 4. This fixes the positions of the housing 8 and the marker pen 9 simultaneously, keeping the tape measure 5 stationary relative to the measurement position. This prevents the slide plate 4 from sliding and affecting the accuracy of the measurement data when the staff measures the leg circumference with the tape measure 5.

[0021] Reference Figure 4 As shown in this embodiment: a spring 14 is fixedly connected to the bottom of the slider 7, and the bottom of the spring 14 is fixedly connected to the inner wall of the housing 8. When the user pushes the housing 8 downwards and slides it along the slider 7 and the slide plate 4, the housing 8 will pull the spring 14 downwards through the slider 7 to store force. When the housing 8 and the marker 9 move down to the patient's patella skin to complete the drawing, the staff releases the housing 8, causing the spring 14 to rebound and pull the housing 8 and the marker 9 upwards, so that the housing 8 and the marker 9 are away from the patient's patella skin, and the position of the housing 8 and the marker 9 is reset for the next use.

[0022] Reference Figure 1 and Figure 2 As shown in this embodiment: both ends of the long plate 15 are T-shaped structures, and T-shaped slots 16 are inserted into both ends of the long plate 15. One side of the T-shaped slot 16 is fixedly connected to the slide plate 4. By inserting the T-shaped slots 16 into the long plate 15, the positions of the left and right long plates 15 can be interchanged, thereby changing the distance between the left and right slide plates 4 and the middle slide plate 4. When the frame 1 is worn in a misaligned and flipped position, it is only necessary to interchange the positions of the two long plates 15 to continue measuring data. The detachable nature of the long plate 15 allows the left and right slide plates 4 to move flexibly, thereby flexibly changing their positions to measure data on the upper and lower sides of the patient's patella according to the actual situation during measurement.

[0023] Reference Figure 2 and Figure 3As shown in this embodiment: a metal sheet 17 is fixedly connected to the surface of the measuring tape 5. The metal sheet 17 is made of stainless steel and has shape memory properties. By using stainless steel and heat-treating it to have special shape memory, the metal sheet 17 always curls inward. When the metal sheet 17 and the measuring tape 5 are wrapped around the patient's leg, the curl of the metal sheet 17 will fit tightly against the outer edge of the patient's leg. At the same time, the metal sheet 17 restricts the left and right movement of the measuring tape 5, ensuring that the measuring tape 5 can only stay on the same horizontal plane during the measurement process, so as to avoid the measuring tape 5 tilting when wrapping around the patient's leg, thereby ensuring the accurate alignment of the measurement points and avoiding adverse effects on the final measurement results.

[0024] Reference Figure 1 - Figure 4 As shown in this embodiment: the dimensions on the surface of the dental plate 10 are a central axis symmetrical figure. The marker pen 9 is placed on the central axis of the dental plate 10. When the upper and lower edge measurement lines of the patella are drawn by the marker pen 9, the operator moves the slide plate 4 along the surface of the long rod 3, so that the dental plate 10 is placed between the upper and lower line segments of the patella. Due to the central axis symmetry of the dimensions on the surface of the dental plate 10, the operator can observe the bottom area of ​​the dental plate 10 through the transparent acrylic material of the dental plate 10 after looking down at it. When the upper and lower line segments of the patella are horizontally aligned with the dimensions at both ends of the dental plate 10, the marker pen 9 will be at the center point of the two line segments, thus directly obtaining the center of the patella. This eliminates the need for a tedious calculation process and greatly improves the measurement efficiency and accuracy.

[0025] Working principle: Medical personnel place the magic strap 2 on the patient's leg, positioning the frame 1 on one side of the patient's leg. The user pushes the slide plate 4 along the long rod 3 to the patient's knee, then presses down on the housing 8, sliding it downwards along the slider 7 to bring the marker pen 9 close to the upper edge of the patient's patella. The housing 8 is then pushed, causing the slider 7 to slide along the slide rod 6, allowing the marker pen 9 to draw a straight line at the upper edge of the patella. A straight line is then drawn at the lower edge of the patella using the same method. The center point between the upper and lower edges of the patella is measured using the toothed plate 10, and a straight line is drawn using the marker pen 9 to obtain the midpoint line of the patient's patella. The marker pen 9 is precisely aligned perpendicularly to the housing 8 to the midpoint line. The design of two long plates 15 of different lengths further enhances the effect. The distance between the three skateboards 4 is restricted by the long board 15. The left long board 15 ensures that the distance between the left measuring tape 5 and the midpoint line drawn by the marker 9 is 15cm, and the right long board 15 ensures that the distance between the right measuring tape 5 and the midpoint line is 10cm. The two measuring tapes 5 are positioned 15cm and 10cm from the center point of the patient's patella, respectively. Finally, medical personnel wrap the measuring tapes 5 around the patient's leg and read the data to obtain the required measurement results. The cooperation between the frame 1 and the Velcro strap 2 ensures the stability of the device after wearing, preventing displacement between the patient's leg and the device during measurement. Simultaneously, the frame 1 restricts the patient's leg, keeping it in a straight line to prevent bending of the leg from affecting the measurement. To ensure measurement accuracy, after obtaining the midpoint line of the patient's patella using the marker 9, the distance between the upper and lower parts of the patella and the leg is directly limited by the long plate 15, ensuring the accuracy of the measurement positions of the two measuring tapes 5 relative to the midpoint line of the patella. After the medical staff confirms the positions of the upper, middle, and lower parts of the patient's patella using the marker 9, the compression rod 13 is threadedly connected to the extension plate 12. Then, the compression rod 13 is screwed into the anti-slip groove 11, and one end of the compression rod 13 is pressed tightly against the inner wall of the anti-slip groove 11, fixing the position of the middle slide plate 4. This simultaneously fixes the positions of the housing 8 and the marker 9. When the user pushes the housing 8 downwards and slides it along the slider 7 and the slide plate 4, the housing 8 will pull the spring downwards through the slider 7. 14. Extend and store energy. When the housing 8 and marker 9 move down to the patient's patellar skin to complete the drawing, the staff releases the housing 8, causing the spring 14 to rebound and pull the housing 8 and marker 9 upward, so that the housing 8 and marker 9 are away from the patient's patellar skin, and the position of the housing 8 and marker 9 is reset. Through the insertion of the T-shaped slot 16 and the long plate 15, the positions of the left and right long plates 15 can be interchanged, thereby changing the distance between the left and right slide plates 4 and the middle slide plate 4. When the frame 1 is worn misaligned and flipped, it is only necessary to interchange the positions of the two long plates 15 to continue measuring data. The detachable nature of the long plate 15 allows the left and right slide plates 4 to move flexibly.
