Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a leg elevation measurement aid for lumbar disc herniation. Background Technology
[0002] The straight leg raise test can be used to identify which intervertebral discs are herniated in patients with lumbar disc herniation. The test involves the patient lying supine with both legs extended. The examiner typically supports the patient's knees to keep them straight, while holding the ankles with the other hand and slowly raising the leg until radiating pain occurs. The angle between the leg and the bed is recorded; this is the angle of the straight leg raise. A normal range is 80-90 degrees. A positive result is indicated if the leg raise is less than 70 degrees and accompanied by radiating pain in the back of the leg. An enhanced straight leg raise test involves adding dorsiflexion of the foot to further stretch the sciatic nerve, resulting in more pronounced radicular pain. The principle behind the straight leg raise test is that raising the leg stretches the sciatic nerve, exacerbating the nerve stimulation associated with a herniated lumbar disc.
[0003] Currently, when medical staff conduct tests on patients, multiple people need to work together. One person holds the patient's leg and raises it for testing, while another person records the angle. This is quite wasteful of manpower. At the same time, medical staff need to constantly observe the angle of the patient's leg raising. When their attention is not focused, errors are easily made, making the operation quite inconvenient.
[0004] Therefore, there is a need for a leg raise measurement aid for lumbar disc herniation that is self-detecting, easy to operate, and highly practical. Utility Model Content
[0005] To address the aforementioned problems in the existing technology, this utility model provides a leg elevation measurement aid for lumbar disc herniation, which is easy to use and highly practical.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a leg raise measurement aid for lumbar disc herniation, comprising a base pad, an adjusting pad on the top surface of the base pad, a measuring frame penetrating the inner side of the adjusting pad, the measuring frame comprising a U-shaped rotating rod and a U-shaped moving cylinder, the U-shaped rotating rod penetrating the adjusting pad, and the U-shaped moving cylinder movably sleeved on the outer sides of both ends of the U-shaped rotating rod, symmetrically fixed inclined supports on the top edge of the base pad, a moving groove on the side wall of the inclined supports, the U-shaped moving cylinder penetrating the moving groove, and symmetrically fixed protractors on the two side walls of the adjusting pad.
[0007] As a preferred technical solution of the lumbar disc herniation leg elevation measurement aid of this utility model, a friction pad is fixed on the inner wall of the moving groove, and the friction pad is located on one side of the U-shaped moving cylinder.
[0008] As a preferred technical solution of the lumbar disc herniation leg elevation measurement aid of this utility model, the adjustment pad includes a movable pad, the protractor is fixed on the side wall of the movable pad, a T-shaped sliding plate is fixed at the bottom of the movable pad, a T-shaped groove is provided in the middle of the top surface of the bottom pad, and the T-shaped sliding plate is located inside the T-shaped groove.
[0009] As a preferred technical solution of the lumbar disc herniation leg elevation measurement aid of this utility model, the moving pad has a rotating hole through the middle, and the middle of the U-shaped rotating rod is located inside the rotating hole.
[0010] As a preferred technical solution of the lumbar disc herniation leg elevation measurement aid of this utility model, a limiting groove is provided in the middle of the inner wall of the rotating hole, and a limiting ring is fixed on the outer wall of the middle part of the U-shaped rotating rod, and the limiting ring is located inside the limiting groove.

[0012] As a preferred technical solution of the leg elevation measurement aid for lumbar disc herniation according to this utility model, the protractor is provided with a scale groove on the side wall.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In use, this invention, through its base pad, inclined support, adjusting pad, and measuring frame, allows for the detection of lumbar disc herniation in patients. The patient lies on the base pad with their lower back above the adjusting pad and their feet below the U-shaped moving cylinder of the measuring frame. During measurement, the patient straightens and lifts their leg, causing the U-shaped moving cylinder to move inside the inclined support. The operation stops when the patient experiences radiating pain, at which point the U-shaped moving cylinder is frictionally limited inside the inclined support. Medical staff can accurately determine the angle of the patient's leg lift by observing the corresponding angle between the U-shaped rotating rod and the protractor on the measuring frame. The measurement results are intuitive and continuously available, facilitating recording by medical staff. Furthermore, patients can perform the test independently without the need for constant support from medical staff, further improving the convenience of the testing operation.
[0015] Furthermore, by setting a T-shaped groove on the base pad and a T-shaped sliding plate at the bottom of the adjustment pad, the T-shaped sliding plate can move inside the T-shaped groove, allowing the position of the adjustment pad to be flexibly adjusted according to the patient's body shape. This makes it easy to operate and highly practical. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example
[0024] Please see Figure 1-4 This utility model provides the following technical solution: a leg raise measurement aid for lumbar disc herniation, including a base pad 1, an adjusting pad 3 on the top surface of the base pad 1, and a measuring frame 4 penetrating the inner side of the adjusting pad 3, as shown in the attached drawing. Figure 1 Appendix Figure 2 and attached Figure 3The measuring frame 4 includes a U-shaped rotating rod 41 and a U-shaped moving cylinder 42. The U-shaped rotating rod 41 passes through the adjusting pad 3, meaning the adjusting pad 3 is located in the middle of the U-shaped rotating rod 41. The U-shaped moving cylinder 42 is movably sleeved on the outer sides of both ends of the U-shaped rotating rod 41, allowing the U-shaped moving cylinder 42 to move on the U-shaped rotating rod 41, thereby adjusting the overall length of the measuring frame 4. An inclined support 2 is symmetrically fixed to the top edge of the bottom pad 1, its inclined design allowing the measuring frame 4 to rotate to a vertical position. A moving groove 21 is provided on the side wall of the inclined support 2, through which the U-shaped moving cylinder 42 passes. Protractors 32 are symmetrically fixed to the two side walls of the adjusting pad 3. The side wall is equipped with a graduated groove 321, which can display the angle of the patient's leg elevation. When this method is used to examine patients with lumbar disc herniation, the patient lies on the base pad 1, with the waist on the adjustment pad 3 and the feet below the middle of one end of the U-shaped moving cylinder 42. The medical staff presses the patient's knee to straighten the patient's leg, and then the patient's leg is raised, which moves the U-shaped moving cylinder 42 inside the moving groove 21. It stops when the patient feels pain. The medical staff can judge the angle of the patient's leg elevation by observing the angle on the protractor 32 corresponding to the U-shaped rotating rod 41. The overall operation is convenient and does not require the medical staff to manually raise the patient's leg, which is more convenient.
[0025] Reference Figure 2 As shown, specifically, a friction pad 22 is fixed to the inner wall of the moving groove 21, and the friction pad 22 is located on one side of the U-shaped moving cylinder 42; multiple friction pads 22 are provided, and the friction pads 22 are made of flexible material, which can rub and position the U-shaped moving cylinder 42, so that after the patient's leg is raised to a certain height, the U-shaped moving cylinder 42 can maintain the raised position, which makes it convenient for medical staff to record the corresponding angle of the U-shaped rotating rod 41. There is no need for medical staff to support the U-shaped moving cylinder 42, so that one medical staff can perform the detection and recording operation, saving manpower.
[0026] Reference Figure 4 As shown, specifically, the adjusting pad 3 includes a movable pad 31, a protractor 32 fixed to the side wall of the movable pad 31, a T-shaped sliding plate 313 fixed to the bottom of the movable pad 31, a T-shaped groove 11 provided in the middle of the top surface of the bottom pad 1, and the T-shaped sliding plate 313 located inside the T-shaped groove 11; medical staff can move the movable pad 31 so that the U-shaped rotating rod 41 moves inside the U-shaped movable cylinder 42, thereby lengthening the overall measuring frame 4, making it suitable for patients of different body types.
[0027] Reference Figure 4As shown, specifically, a rotating hole 311 is passed through the middle of the movable pad 31, and the middle of the U-shaped rotating rod 41 is located inside the rotating hole 311; a limiting groove 312 is provided in the middle of the inner wall of the rotating hole 311, and a limiting ring 411 is fixed to the outer wall of the middle of the U-shaped rotating rod 41. The limiting ring 411 is located inside the limiting groove 312, which can limit the U-shaped rotating rod 41, making its rotation more stable and less prone to slippage.
[0028] The working principle and usage process of this utility model are as follows: When measuring a patient, the position of the sliding pad 31 is adjusted according to the patient's body shape. The patient then lies on the base pad 1 with their waist above the sliding pad 31 and their feet below the U-shaped sliding cylinder 42. The medical staff presses down on the patient's knee to straighten their leg, and then the patient raises their leg, moving the U-shaped sliding cylinder 42 inside the sliding groove 21. When the patient's leg is raised to a height where they feel pain, the leg is lowered, and the U-shaped sliding cylinder 42 is positioned at the corresponding height inside the sliding groove 21. The medical staff can easily record the angle of the patient's leg raising by observing the angle on the protractor 32 corresponding to the U-shaped rotating rod 41. The operation is convenient, can be performed by a single person, and is highly practical.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
