Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a tool for measuring the circumference of the upper and lower legs above the patella. Background Technology

[0002] Deep vein thrombosis (DVT) in the lower extremities usually causes swelling. One way to determine if a patient has DVT is to measure the circumference of both legs separately and compare them. Specifically, for each leg, measure the circumference 15 cm above the patella and 10 cm below the patella.

[0003] Currently, a soft measuring tape is generally used to measure leg circumference. The measurer wraps the tape around the patient's leg and holds it tightly to measure the circumference. However, different medical professionals may use different measuring techniques and apply different pressure, which can lead to inaccurate results. For example, inconsistent tightness of the tape can result in inaccurate leg circumference readings. Furthermore, it is difficult to accurately determine the positions 15cm above the patella and 10cm below the patella, especially for obese patients or those with leg deformities. This can lead to measurement errors and affect the diagnosis of the condition. Utility Model Content

[0017] Beneficial effects

[0018] In this invention, the patella position is determined by a fixing component, and fixed distances are taken to the upper and lower sides of the patella based on the patella position. The circumferences at these two locations are measured using a measuring ruler. Generally, the upper edge of the patella is measured at 15cm of the thigh circumference, and the lower edge of the patella is measured at 10cm of the calf circumference. This device can accurately locate the required positions of the upper and lower edges of the patella. Furthermore, the extension and retraction of the first and second telescopic rulers allow for appropriate fine-tuning according to the patient's body shape or posture. Since simultaneous measurement of the upper and lower edges of the patella is required, the fixing component is fixed to the patient's patella, and the first telescopic ruler at either end is limited. This ensures that the patella will not shift when adjusting the other side after fixing one side, guaranteeing measurement accuracy. The adjustable first and second telescopic rulers further broaden the applicability of this device. Attached Figure Description

[0033] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0034] Example: Please refer to Figures 1 to 5 :

[0035] like Figure 1 As shown, this utility model proposes a tool for measuring the circumference of the thigh above and below the patella, comprising:

[0036] The fixation member 1 with the elastic band 301 is fixed to the front end of the patella by the elastic band 301;

[0037] The upper and lower ends of the fixing member 1 are respectively connected to the first telescopic ruler 401, and the first telescopic ruler 401 has a cavity inside; the second telescopic ruler 402 is inserted into the cavity of the first telescopic ruler 401; the end of the second telescopic ruler 402 is connected to the ring measuring ruler 5.

[0038] The second telescopic ruler 402 extends and retracts along the cavity of the first telescopic ruler 401.

[0039] Among them, such as Figure 2 As shown, the fixation member 1 has a contact member 2 on the side near the patella; the contact member 2 is made of a flexible and elastic material; the contact member 2 is in direct contact with the patella, making the fixation member 1 more comfortable when fixed at the front of the patient's patella.

[0040] Among them, such as Figure 2 As shown, an elastic band 301 is connected to the side of the fixation member 1 near the patella; the elastic band 301 fixes the fixation member 1 to the front end of the patient's patella.

[0041] Among them, such as Figure 2 As shown, the fixing member 1 has a winding member 3 inside, and a through hole 103 is opened on one end face of the fixing member 1 near the winding member 3; the winding member 3 is rotatably connected to the fixing member 1, and there is damping between the winding member 3 and the fixing member 1; one end of the elastic band 301 is fixedly connected to the winding member 3 and passes through the through hole 103, and wraps around the outside of the winding member 3 when the winding member 3 rotates; by rotating the winding member 3 to tighten the elastic band 301, the contact between the device and the patella is made closer, while ensuring the stability of the fixing member 1 at the patella; in which In one embodiment, the tightened elastic band 301 and the flexible contact 2 make the device fit more closely to the patella, while increasing the friction between the contact 2 and the front end of the patella, preventing the fixation member 1 from slipping off the patella; when the device is not in use, the winding member 3 can also be used to store the elastic band 301; in another embodiment, due to the special position of the patella in the human body, when the width of the elastic band 301 is sufficient, the elastic band 301 can cover the flexion of the leg opposite the patella, and tightening the elastic band 301 can help the patient keep the leg straight, ensuring the accuracy of the measurement.

[0042] Among them, such as Figure 2 As shown, the end face of the fixing member 1 away from the winding member 3 is provided with a slot 102; the end of the elastic band 301 away from the winding member 3 is provided with a buckle; the buckle of the elastic band 301 is inserted into the slot 102.

[0043] Among them, such as Figure 3 As shown, the first telescopic ruler 401 has a screw hole at one end near the extension direction of the second telescopic ruler 402, and a limiting member 403 is connected inside the screw hole by a thread; the displacement of the second telescopic ruler 402 is limited by the limiting member 403. Specifically, after the second telescopic ruler 402 extends a certain length, the displacement of the second telescopic ruler 402 is limited by tightening the limiting member 403 and the friction generated by the compression between the limiting member 403 and the second telescopic ruler 402.

[0044] Among them, such as Figure 3As shown, the first telescopic ruler 401 and the second telescopic ruler 402 are provided with scales. When the first telescopic ruler 401 is fully extended from the storage slot 101, the zero mark of the first telescopic ruler 401 is aligned with the edge of the storage slot 101. The final mark of the first telescopic ruler 401 is located at the edge of the first telescopic ruler 401, and can be aligned with any mark of the second telescopic ruler 402 when the second telescopic ruler 402 is extended or retracted. When the first telescopic ruler 401 is used, it is completely removed from the storage slot 101, and the second telescopic ruler 402 is removed from the first telescopic ruler 401 as appropriate. Let the range of the first telescopic ruler 401 be A, the range of the second telescopic ruler 402 be B, and the mark on the second telescopic ruler 402 that is aligned with the final mark of the first telescopic ruler 401 be C. The final range S of the two is S=A+BC. The amount that the second telescopic ruler 402 needs to extend or retract can be calculated from the range, for example, 15cm above the patella and 10cm below the patella.

[0045] Among them, such as Figure 4 As shown, the surface of measuring ruler 5 is marked with graduations.

[0046] Among them, such as Figure 5 As shown, the measuring ruler 5 is elastic. In the initial state, the measuring ruler is in a rolled-up state. After the measuring ruler 5 is unfolded, it will bend into an arc shape, keeping the measuring ruler 5 in the unfolded state as it was before use. After the measuring ruler 5 is unfolded, when it comes into contact with the measurement position on the patient's leg, the curved structure is restored by hand, and under its own elasticity, it will automatically return to the rolled-up state and wrap around the patient's leg.

[0047] Among them, such as Figure 4 As shown, one end of the measuring ruler 5 is equipped with an indicator 501, which is located at the upper end of the zero mark of the measuring ruler 5. The measuring ruler 5 is wrapped around the leg, with the two ends of the measuring ruler 5 overlapping. The indicator 501 is the zero point of the measuring ruler 5, and the mark of the measuring ruler 5 it points to is the measured circumference of the leg.

[0048] The specific usage and function of this embodiment: In this utility model, the patella position is determined by the fixing member 1, and a fixed distance is taken from the upper and lower sides of the patella based on the patella position. The circumference of the two positions is measured by the measuring ruler 5. Generally, the thigh circumference is taken at 15cm at the upper edge of the patella, and the calf circumference is taken at 10cm at the lower edge of the patella. This device can accurately locate the required positions of the upper and lower edges of the patella. At the same time, by adjusting the extension and retraction of the first telescopic ruler 401 and the second telescopic ruler 402, appropriate fine adjustments can be made according to the patient's body shape or posture. Meanwhile, since the upper and lower edges of the patella need to be measured simultaneously, the fixing member 1 is fixed at the patient's patella, and the first telescopic ruler 401 at either end is limited, which can ensure that the patella will not shift when adjusting the other side after fixing one side, thus ensuring the accuracy of the measurement. The first telescopic ruler 401 and the second telescopic ruler 402 can be adjusted, making the applicability of this device more extensive.
