[0002] A lumbar support device is a wearable device that provides protection, auxiliary treatment, or functional improvement to the lumbar region through physical support, fixation, or pressure.
[0003] After wearing the lumbar support device, the built-in steel bars provide support for the lower back, thereby reducing the burden on the lower back, limiting improper activities, and promoting rehabilitation. However, in actual use, traditional lumbar support devices generally have a fixed support strength. In the early stages of treatment, they can provide greater support to the patient's lower back. However, in the middle and later stages, traditional lumbar support devices may not be able to make corresponding adjustments according to the patient's specific situation. After long-term use, the patient's lower back muscles may become overly dependent on the lumbar support device, which may not only reduce the activity of the lower back muscles but also lead to atrophy of the lower back muscles. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a lumbar support device. This solves the problem that, in practical use, traditional lumbar support devices generally provide fixed support strength. While they can offer significant support to the patient's lower back in the early stages of treatment, they may not be able to adjust to the patient's specific condition in the later stages. Long-term use may lead to excessive dependence on the lumbar support device, resulting in reduced muscle activity and even muscle atrophy.

[0016] In actual use, traditional lumbar support devices generally provide fixed support strength. In the early stages of treatment, they can provide greater support to the patient's lower back. However, in the middle and later stages, traditional lumbar support devices may not be able to make corresponding adjustments according to the patient's specific condition. After long-term use, the patient's lower back muscles may become overly dependent on the lumbar support device, which may not only reduce the activity of the lower back muscles but also lead to atrophy of the lower back muscles.
[0017] In view of this, the present invention provides a lumbar support device, which solves the problem that in actual use, the support strength of traditional lumbar support devices is generally fixed. In the early stage of treatment, it can provide greater support to the patient's waist. However, in the middle and later stages, traditional lumbar support devices may not be able to make corresponding adjustments according to the patient's specific situation. After long-term use, the patient's waist muscles may become overly dependent on the lumbar support device, which may not only reduce the activity of waist muscles, but may also lead to the problem of waist muscle atrophy.
[0018] Example 1, by Figure 1-5It is known that the lumbar support device includes a lumbar support seat 1, with a waist belt 2 fixedly connected to both sides of the lumbar support seat 1, and an adjustment mechanism provided on the back of the lumbar support seat 1; the adjustment mechanism includes a connecting groove 3, an elastic strip 4, a first hook surface 5, and a first rough surface 6; the connecting groove 3 is opened on the back of the lumbar support seat 1, the elastic strip 4 is fixedly connected to the inner wall of the connecting groove 3, the first hook surface 5 is provided on the left side of the elastic strip 4 and is fixedly connected to the back of the lumbar support seat 1, and the first rough surface 6 is provided on the right side of the elastic strip 4 and is fixedly connected to the back of the lumbar support seat 1; In its implementation, it is worth noting that the lumbar support seat 1 is shaped to conform to the curve of the human waist, providing basic support for the lower back. In terms of material selection, the main body of the lumbar support seat 1 is made of highly elastic and breathable ethylene-vinyl acetate copolymer. This material is soft and conforms to the waist while providing good cushioning performance, dispersing external pressure and reducing the burden on the lower back. The waist belt 2 is trapezoidal in shape and can be made of high-strength nylon webbing, capable of withstanding significant tensile force and ensuring durability over long-term use. Three connecting slots 3 are provided, each rectangular with a square cross-section, to accommodate the elastic strip 4. The elastic strip 4 has a certain degree of elasticity, adapting to changes in the waist size of different users, providing a comfortable wearing experience while ensuring support. Its material can be high-elasticity latex yarn, which is highly elastic and has good resilience, maintaining its elasticity without deformation over a long period. The first hook surface 5 and the first rough surface 6 form a Velcro structure, allowing users to adjust the stretch of the elastic strip 4 according to their needs, achieving personalized adjustment. The first hook surface 5 is fixed to the lumbar support seat 1 by a connecting strap. On the back, in actual use, the user wears the lumbar support device on their waist. In the initial state, the first hook surface 5 and the first rough surface 6 on the back of the lumbar support 1 are fixed together, and the elastic strip 4 is restricted by the first hook surface 5 and the first rough surface 6, and will not undergo significant deformation. When it is necessary to adjust the pressure of the lumbar support 1, the user pinches one side of the first hook surface 5 and applies a force away from the first rough surface 6, thereby moving the first hook surface 5 away from the first rough surface 6. In the vertical direction, the remaining three first hook surfaces 5 and first rough surfaces 6 are released in sequence. At this time, one elastic strip 4 is completely released from the restriction of the first hook surface 5 and the first rough surface 6, and the user's waist can make appropriate slight movements, causing the elastic strip 4 to deform, that is, a set of adjustment mechanisms is released. At this time, the pressure on the user's waist changes. It can be understood that multiple sets of adjustment mechanisms can be set as needed, so that they can be used to cooperate with different treatment stages and play a role, ensuring that the lumbar support device can provide better treatment results for the user, thereby improving the adaptability of the lumbar support device. Furthermore, the top and bottom of the lumbar support seat 1 are provided with pressure-distributing mechanisms; the pressure-distributing mechanisms include pressure-distributing belts 7, second hook surfaces 8, second rough surfaces 9, and elastic bands 10; four pressure-distributing belts 7 are provided, and the four pressure-distributing belts 7 are respectively provided on both sides of the outer wall of the lumbar support seat 1, and the four pressure-distributing belts 7 are respectively fixedly connected to the top and bottom of the two waist belts 2. The back of one side of the pressure-distributing belt 7 is fixedly connected to the second hook surface 8, and the back of the other side of the pressure-distributing belt 7 is fixedly connected to the second rough surface 9. An elastic band 10 is provided between the second hook surface 8 and the second rough surface 9, and the outer walls of the elastic band 10 are respectively fixedly connected to the sides of the outer walls of the two pressure-distributing belts 7 that are close to each other; In the specific implementation process, it is worth noting that there are four pressure-distributing bands 7, located at the top and bottom of the two waist belts 2 respectively. The material of the pressure-distributing bands 7 is the same as that of the waist belts 2. The second hook surface 8 and the second rough surface 9 form a Velcro structure, which allows the user to adjust the stretch of the elastic band 10 according to their own needs. There are two elastic bands 10, located above and below the lumbar support seat 1 respectively. The overall shape is similar to an arch, and the material can be rubber. Through the cooperation of the pressure-distributing bands 7, the second hook surface 8, the second rough surface 9 and the elastic band 10, the pressure of the top edge and bottom edge of the lumbar support device can be adjusted according to the user's actual needs. This can effectively relieve the pressure between the waist, the area above the waist, the area below the waist and the edge of the lumbar support device, thereby improving the wearing comfort of the lumbar support device. Furthermore, a malleable steel strip 11 is fixedly connected to the back of both waist belts 2. A first tightening band 12 is fixedly connected to the side of the outer wall of one malleable steel strip 11 away from the first hook surface 5. A third hook surface 13 is fixedly connected to the back of the first tightening band 12. A third rough surface 14 is fixedly connected to the side of the back of the first tightening band 12 away from the third hook surface 13. A second tightening band 15 is fixedly connected to the side of the outer wall of the other malleable steel strip 11 away from the first rough surface 6. A connecting ring 16 is movably connected to the end of the second tightening band 15. In the specific implementation process, it is worth noting that there are two malleable steel strips 11, and their outer walls are covered with protective pads to prevent the malleable steel strips 11 from snagging on the user's clothing. The material of these strips can be a shape memory alloy, which has good flexibility and support, and can automatically adjust its shape according to the waist shape to provide stable support. The first tightening band 12 and the second tightening band 15 are made of the same material, which can be a high-elasticity polyester fiber webbing. The first tightening band 12 is longer than the second tightening band 15. The end of the second tightening band 15 forms a loop, and the outer wall of the connecting ring 16 is inserted into it to achieve a movable connection. There are two connecting rings 16, which are similar to rectangular rings in shape, and their material can be ABS plastic. The third hook surface 1... The third surface 14 and the third textured surface 15 form a Velcro structure, which makes it convenient for the user to adjust the tightening force of the waist belt 2. In actual use, after wearing the waist support device, the user can tighten it through the first tightening strap 12 and the second tightening strap 15. The specific process is as follows: First, the user picks up one of the first tightening straps 12 and moves it so that the first tightening strap 12 passes through the connecting ring 16 and comes out from the front of the connecting ring 16. Then, the user folds the first tightening strap 12 in half and moves the third textured surface 14 closer to the third hook surface 13. This process will gradually tighten the waist belt 2. When the maximum tightening limit is reached, the third textured surface 14 is fixed to the third hook surface 13, which improves the support effect of the waist support device. Example 2, by Figure 1-5 It can be seen that the outer walls of the first tightening belt 12 and the second tightening belt 15 are both fitted with limiting rings 17. There are four limiting rings 17, and the four limiting rings 17 are fixedly connected to the side of the back of the two waist belts 2 away from the two plastic steel strips 11. In the specific implementation process, it is worth noting that there are four limiting rings 17, which can be made of nylon. They are mainly used to limit the first tightening band 12 and the second tightening band 15, so that the first tightening band 12 and the second tightening band 15 will not move to other places, and the position of the tightening force will not shift. When in use, the user can pass the first tightening band 12 and the second tightening band 15 through the limiting rings 17 on both sides, thereby improving the structural stability of the lumbar support device. Furthermore, a massage block 18 is fixedly connected to the front of the lumbar support seat 1; In the specific implementation process, it is worth noting that there are four massage blocks 18, which can be increased or decreased according to actual needs. The material can be medical-grade silicone, which has a smooth surface and a certain degree of hardness. It can ensure the massage effect without harming the skin, and at the same time has good skin affinity and corrosion resistance, thereby improving the therapeutic effect of the lumbar support device. Furthermore, pressure pads 19 are fixedly connected to the front of both waist belts 2; In the specific implementation process, it is worth noting that the pressure pad 19 is roughly circular in shape, which can conform to the user's body curve when the waist belt 2 is tightened, so that the pressure is evenly distributed and avoids discomfort caused by excessive local pressure. The material of the pressure pad 19 can be memory foam, which has good slow rebound characteristics and can automatically conform to the shape of the waist to provide comfortable pressure support. At the same time, it has good breathability to prevent the wearing area from being stuffy and damp, thus improving the comfort of the lumbar support device. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
