Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a lumbar fixation device. Background Technology

[0002] In daily life and rehabilitation, patients with lumbar diseases and those recovering from surgery often experience lumbar muscle strain, excessive pressure on the lumbar spine, and even lumbar disc herniation due to prolonged sitting, improper exercise, or pathological reasons. In the field of medical devices, existing lumbar fixation rehabilitation devices mostly adopt a basic strap design, lacking personalized adjustment mechanisms for different patient body shapes. They cannot achieve a scientific balance between strength and comfort during rehabilitation, providing only limited static support and failing to flexibly adjust the fixation strength according to different users' lumbar dimensions and usage needs. This makes it difficult to meet the professional requirements of precise lumbar fixation and dynamic support in clinical treatment. Therefore, there is an urgent need for a lumbar fixation device with good support performance and flexible adjustable fixation strength to address the shortcomings of existing products. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a lumbar support device to solve the issues of poor support and insufficient adjustment flexibility in existing lumbar support products.

[0004] To address the problems mentioned in the background section and achieve the aforementioned technical objectives, this utility model provides the following technical solution: A lumbar support device includes a waist belt, a main support member, an elastic band, and an adjustment mechanism. The waist belt has hook-and-loop fasteners at both ends, which connect to form a wrap around the waist. The main support member is fixedly connected to the rear side of the waist belt at a position corresponding to the lumbar vertebrae. Each hook-and-loop fastener at both ends of the waist belt is connected to one of the adjustment mechanisms. One end of the elastic band is connected to the adjustment mechanism, and the other end is connected to an adjacent side of the main support member.

[0005] Furthermore, the adjustment mechanism includes an adjustment belt and a connecting buckle; one end of the adjustment belt is fixedly connected to the hook and loop fastener, and the other end is detachably connected to the connecting buckle; the elastic band is fixedly connected to the connecting buckle.

[0006] Furthermore, the adjustment mechanism adopts an adjustment knob, which is fixedly connected to the hook and loop fastener. The adjustment knob has a pulley inside, which is fixedly connected to one end of the elastic band. When the pulley rotates, it drives the elastic band to extend and retract.

[0007] Furthermore, each side of the main support member is connected to a plurality of elastic bands.

[0008] Furthermore, the main support component is made of shape memory alloy or engineering plastic material.

[0009] Furthermore, the elastic band is made of nylon or spandex material.

[0010] Furthermore, the belt is also provided with several support strips.

[0011] The beneficial effects of this utility model are as follows: The lumbar fixation device of this utility model achieves waist belt length adjustment through hook and loop fasteners, which can adapt to the waist size of different users and ensure that the waist belt can tightly wrap the waist; the support component accurately corresponds to the lumbar spine position, which can directly provide rigid support to the lumbar spine, effectively disperse the pressure on the lumbar spine, and avoid damage to the lumbar spine due to excessive pressure; the elastic tension of the elastic band can help enhance the support effect, and the elasticity can adapt to slight waist movements, avoiding the restriction of movement caused by excessive fixation, and improving the comfort of use; the length of the elastic band can also be flexibly adjusted through the adjustment mechanism, thereby changing the fixation force of the lumbar fixation device on the waist, which is suitable for users with different waist sizes and can also meet the different fixation force needs of users in different scenarios (such as daily office, sports protection, postoperative rehabilitation).

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] Example 1: like Figures 1 to 4 As shown, a lumbar support device includes a lumbar belt 1, a main support component 2, an elastic band 3, and an adjustment mechanism 4. Its specific structural composition, connection method, and working principle are as follows: The waist belt 1 serves as the basic load-bearing component of the lumbar support system. It has hook-and-loop fasteners 5 at both ends, with the hook and loop sides of the fasteners 5 corresponding to the ends of the waist belt 1. By connecting the hook-and-loop fasteners 5 at both ends of the waist belt 1, it can wrap around the waist and form a tight wrap. To further enhance the support and shaping effect of the lumbar support system, the waist belt 1 also includes several support strips 6, such as elastic plastic strips or carbon fiber strips. When a user wears the waist belt 1 and it is wrapped by the hook and loop fastener 5, the support strips 6 inside the waist belt 1 maintain the overall shape of the waist belt 1 due to their own flexibility or semi-rigidity, preventing the waist belt 1 from becoming excessively wrinkled or deformed due to waist activities (such as bending over or turning to the side), and ensuring that the waist belt 1 always fits the waist curve. The support strips 6, through their synergistic effect with the waist belt 1, distribute the pressure on the waist to multiple support strips 6, and then the support strips 6 transmit it to the waist belt 1 as a whole, avoiding discomfort in the waist caused by local pressure concentration. At the same time, the presence of the support strips 6 can enhance the auxiliary support of the waist belt 1 for the waist muscles, reduce the strain on the muscles caused by maintaining body posture, and relieve the fatigue of the waist muscles, especially when sitting or standing for a long time.

[0018] The main support component 2 is made of high-strength, lightweight materials, such as shape memory alloy or engineering plastics, providing excellent lumbar support. Its shape conforms to the curve of the human waist, increasing wearing comfort. The main support component 2 is fixedly connected to the back of the waist belt 1 at the position corresponding to the lumbar spine through sewing, bonding, or buckle connection. The installation position of the main support component 2 corresponds to the physiological curve of the human lumbar spine, ensuring that the main support component 2 can accurately support the lumbar spine.

[0019] There are two adjustment mechanisms 4. Each of the hook and loop fasteners 5 at both ends of the waist belt 1 is fixedly connected to an adjustment mechanism 4. The connection method can be sewing, bolt fixing or one-piece molding. The installation position of the adjustment mechanism 4 is located on the outside of the hook and loop fastener 5 at the end of the waist belt 1, so as not to affect the normal use of the hook and loop fastener 5.

[0020] The elastic band 3 is made of nylon or spandex, both of which possess excellent elasticity and elastic recovery capabilities, maintaining stable tensile force output over a long period. This prevents a decrease in fixation strength due to elasticity decay, ensuring the long-term effectiveness of the lumbar support device. The elastic band 3 is connected at both ends to the adjustment mechanism 4 and the main support member 2, respectively. Specifically, one end of the elastic band 3 is fixedly or detachably connected to the adjustment mechanism 4, and the other end is connected to the adjacent side of the main support member 2 (i.e., the side of the main support member 2 closest to the adjustment mechanism 4). When in its natural state, the length of the elastic band 3 is adapted to the distance from the main support member 2 at the rear of the waist belt 1 to the adjustment mechanism 4 at the end of the waist belt 1, ensuring that the elastic band 3 maintains a certain pretension after the waist belt 1 wraps around the waist. In this embodiment, multiple elastic bands 3 are connected to each side of the main support member 2. Specifically, multiple connection points are evenly spaced on both sides of the main support member 2. The connection points can be structures such as sewing holes, buckle seats, or adhesive areas. The number of connection points is determined according to the length of the main support member 2 and the width of the elastic band 3. Usually, 2-4 connection points are set on each side. The number of elastic bands 3 is the same as the number of connection points on both sides of the main support member 2. One end of each elastic band 3 is fixedly connected to a connection point on the side of the main support member 2, and the other end is fixedly connected to the adjustment mechanism 4 at the end of the waist belt 1. The multiple elastic bands 3 are evenly distributed on the side of the main support member 2 to ensure that the tension can be evenly transmitted to the main support member 2.

[0021] The working principle of the lumbar fixation device of this application is as follows: When the user uses the lumbar fixation device, firstly, the waist belt 1 is wrapped around the waist. According to the user's own waist size, the waist belt 1 is initially wrapped around the waist by adjusting the fitting length of the hook and loop fasteners 5 at both ends of the waist belt 1. At this time, the main support 2 is fixed to the back of the waist belt 1 and corresponds to the lumbar spine. It will directly contact the back of the lumbar spine, forming an initial rigid support for the lumbar spine, effectively dispersing the pressure on the lumbar spine and avoiding damage to the lumbar spine due to excessive pressure. Subsequently, by operating the adjustment mechanisms 4 at both ends of the waist belt 1, the length of the elastic band 3 can be adjusted: when the adjustment mechanism 4 shortens the length of the elastic band 3, the elastic band 3 will generate a pulling force to both sides. This pulling force is transmitted to both sides of the lumbar spine through the main support member 2, further enhancing the support of the main support member 2 for the lumbar spine. At the same time, the elastic tension of the elastic band 3 can also form a flexible restraint on the lumbar muscles, relieving the tension of the lumbar muscles. When it is necessary to reduce the fixing force, the length of the elastic band 3 can be extended by adjusting the mechanism 4. The tension of the elastic band 3 is reduced, and the restraint and support force on the waist is reduced accordingly, realizing flexible adjustment of the fixing force.

[0022] The lumbar fixation device of this application allows for length adjustment of the waist belt 1 via hook and loop fastener 5, which can accommodate different users' waist sizes and ensure that the waist belt 1 can tightly wrap around the waist. The support component precisely corresponds to the lumbar spine position, which can directly provide rigid support to the lumbar spine, effectively dispersing the pressure on the lumbar spine and preventing damage to the lumbar spine due to excessive pressure. The elastic tension of the elastic band 3 can help enhance the support effect, and its elasticity can adapt to slight movements of the waist, avoiding the restriction of movement caused by excessive fixation and improving the comfort of use. The length of the elastic band 3 can also be flexibly adjusted by the adjustment mechanism 4, thereby changing the fixation force of the lumbar fixation device on the waist. It is suitable for users with different waist sizes and can also meet the different fixation force needs of users in different scenarios (such as daily office work, sports protection, and postoperative rehabilitation).

[0023] In this implementation plan, see Figures 2 to 4 The adjustment mechanism 4 employs an adjustment belt 41 and a connecting buckle 42. One end of the adjustment belt 41 is fixedly connected to the hook and loop fastener 5 by sewing or heat fusion bonding, while the other end is detachably connected to the connecting buckle 42 by a snap fastener or Velcro. One end of the elastic band 3 is fixedly connected to the connecting buckle 42, and the other end is connected to the main support member 2. When it is necessary to adjust the extension length of the elastic band 3, the overall length of the adjustment mechanism 4 can be adjusted by adjusting the connection length between the adjustment belt 41 and the connecting buckle 42, thereby causing the elastic band 3 to extend or retract. This increases or decreases the tension of the elastic band 3 on the main support member 2, thus strengthening or weakening the waist fixation force. The adjustment operation is convenient and suitable for quick daily adjustments. Example 2: The difference between this embodiment and Embodiment 1 is that the adjustment mechanism uses a different structure: an adjustment knob. Specifically, the adjustment knob is fixedly connected to the Velcro 5 by bolts, adhesive, or integral molding. The outer side of the adjustment knob housing has anti-slip textures to facilitate user rotation. The inner side of the housing is hollow, and a pulley is rotatably installed inside. The pulley is connected to the inner wall of the adjustment knob housing via a rotating shaft. Both ends of the rotating shaft are fixed to the inner wall of the housing, and the pulley can rotate freely around the rotating shaft. One end of the elastic band 3 passes through the opening in the adjustment knob housing, extends into the adjustment knob, and is fixedly connected to the outer circumference of the pulley. The size of the opening in the adjustment knob housing is adapted to the width of the elastic band 3 to ensure that the elastic band 3 can extend and retract smoothly and avoid jamming.

[0024] When the user needs to adjust the length of the elastic band 3, rotating the housing of the adjustment knob causes the internal pulley to rotate synchronously. For example, if the adjustment knob is rotated clockwise, the pulley will wrap the elastic band 3 around its outer circumference, increasing the length of the elastic band 3 extending into the adjustment knob, thereby shortening the effective length of the elastic band 3 outside the adjustment knob. The elastic band 3 is stretched, generating greater tension, which is transmitted to the waist through the main support 2, enhancing the fixing force. If the adjustment knob is rotated counterclockwise, the elastic band 3 wrapped on the pulley will gradually loosen, extending the effective length of the elastic band 3 outside, reducing the stretch, decreasing the tension, and weakening the fixing force at the waist. Simultaneously, the adjustment knob can be equipped with a ratchet and pawl structure. When the adjustment knob is rotated to the desired position, the ratchet and pawl can automatically lock the rotation of the pulley, preventing the elastic band 3 from reversing due to its own elasticity, ensuring the stability of the adjusted length. The rotation of the pulley drives the extension and retraction of the elastic band 3.
