Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of lumbar disc protection equipment, and more specifically, to a protective device for patients with lumbar disc injuries. Background Technology

[0002] For patients with lumbar disc injuries, appropriate assistive devices are needed during treatment and rehabilitation to reduce lumbar pressure, maintain lumbar spine stability, and promote recovery. Traditional lumbar support devices, such as ordinary lumbar braces, can provide some support, but they have many limitations. Their support strength is often fixed and difficult to adjust flexibly according to individual patient differences and different stages of rehabilitation. After prolonged wear, problems such as weakened support and poor fit may occur. Some so-called lumbar spine protection chairs on the market only focus on simple lumbar support and lack comprehensive and precise support and dynamic adjustment functions for the lumbar spine. They cannot effectively relieve the pressure on the lumbar discs and cannot meet the actual needs of patients with lumbar disc injuries in daily life and rehabilitation training. Against this background, it is urgent to develop a protective device that can flexibly adjust the support strength according to the patient's needs, has good fit and stability, and can help patients adjust their sitting posture and reduce the burden on the lumbar spine.

[0031] like Figures 1-4 As shown, a protective device for patients with lumbar disc injury according to this disclosure is illustrated, comprising:

[0032] Seat 1, with cushions 2 provided on the side walls of seat 1;

[0033] Lumbar support component 3 is disposed on the side wall of the backrest 2;

[0034] Self-rotating positioning component 4, which is mounted on the base plate 1;

[0035] The lumbar support component 3 includes a limiting tube 3-1, which is disposed on the side wall of the cushion 2 and is connected to the cushion 2. A drive shaft 3-2 is disposed inside the limiting tube 3-1, and a screw thread 3-3 is disposed on the outer side wall of the drive shaft 3-2. The screw thread 3-3 engages with the limiting tube 3-1. A lumbar support pad 3-4 is disposed on the side wall of the drive shaft 3-2, and the lumbar support pad 3-4 corresponds to the position of the human waist.

[0036] The self-rotating positioning component 4 includes a fixed ring 4-1, which is disposed on the outer side wall of the seat plate 1. The inner side wall of the fixed ring 4-1 has a positioning cavity 4-2. The inner side wall of the positioning cavity 4-2 is provided with a fixing frame 4-3. The fixing frame 4-3 is provided with a fixing shaft 4-4. A movable ball 4-5 is fitted on the fixing shaft 4-4.

[0037] In some examples, the seat plate 1, as the basic support component of the entire device, can be made of a sturdy and heavy material, such as high-density plastic or lightweight metal alloy, to ensure stability during use. Its shape design should conform to ergonomics, and the edges can be rounded to prevent scratches to the user. The backrest 2 is installed on the side wall of the seat plate 1 to provide support and comfort for the lower back. The backrest 2 can be made of soft and elastic sponge material, covered with breathable fabric, such as cotton or blended fabric, to ensure comfort and facilitate air circulation, reducing stuffiness. The backrest 2 can be connected to the seat plate 1 by bolt fixing or strong adhesive, ensuring that it will not shift during use. The limiting tube 3-1 is set on the side wall of the backrest 2 and is connected to the inside of the backrest 2. The limiting tube 3-1 can be made of metal, such as aluminum alloy, to ensure its strength and durability. Its interior is machined with internal threads that match the screw threads 3-3 of the drive shaft 3-2, ensuring that the drive shaft 3-2 can rotate smoothly and move axially within it.

[0038] The drive shaft 3-2 is located inside the limiting tube 3-1, and its outer wall is machined with screw threads 3-3. The drive shaft 3-2 can be made of stainless steel, which has good strength and corrosion resistance. A hand-cranking disc 11 is installed at one end of the drive shaft 3-2 (located outside the cushion 2). The hand-cranking disc 11 can be a large-diameter plastic disc, making it convenient for the patient to hold and rotate the drive shaft 3-2. When the patient rotates the hand-cranking disc 11, the drive shaft 3-2 will move axially along the thread direction within the limiting tube 3-1, supporting the lumbar support. The support pad 3-4 is installed on the side wall of the drive shaft 3-2 and corresponds to the position of the human waist. The waist support pad 3-4 can be made of memory foam or silicone, which have good support and shaping ability. The fixing ring 4-1 is set on the outer side wall of the seat plate 1 and can be firmly fixed to the seat plate 1 by welding or bolt connection. The fixing ring 4-1 is made of metal, such as carbon steel, to ensure its strength. The inner side wall of the fixing ring 4-1 is machined with a positioning cavity 4-2 for installing the fixing bracket 4-3 and the movable ball 4-5 and other components.

[0039] The fixing frame 4-3 is installed on the inner wall of the positioning cavity 4-2 and can be fixed by welding or bolt connection. The fixing frame 4-3 can be made of metal, and its shape and structural design should be able to stably support the fixing shaft 4-4. The fixing shaft 4-4 is installed on the fixing frame 4-3 and can be fixed to the fixing frame 4-3 by interference fit or key connection. The fixing shaft 4-4 is made of metal, such as stainless steel. The movable ball 4-5 is fitted on the fixing shaft 4-4. The movable ball 4-5 can be made of wear-resistant metal or high-strength engineering plastic. The movable ball 4-5 can rotate freely on the fixing shaft 4-4, and part of it is embedded in the connecting cavity 4-6 opened on the outer wall of the seat plate 1. This design allows the seat plate 1 to rotate at a certain angle with the movable ball 4-5 as the center, which is convenient for the patient to adjust the sitting posture and body direction. At the same time, the positioning cavity 4-2 and the fixing frame 4-3 can limit and support the movable ball 4-5 to ensure the stability of the entire structure.

[0040] like Figures 1-4 As shown in the figure, this embodiment proposes that the outer side wall of the cushion 2 is provided with a limiting ring 3-5, and the limiting ring 3-5 is provided with a limiting shaft 3-6 inside, and the limiting shaft 3-6 is fixedly connected to the cushion 2.

[0041] In some examples, a limiting ring 3-5 is provided on the outer wall of the cushion 2. The limiting ring 3-5 can be made of metal or plastic and is fixed to the cushion 2 by bolts or glue. A limiting shaft 3-6 is provided inside the limiting ring 3-5. The limiting shaft 3-6 is fixedly connected to the cushion 2 by means of welding. The limiting shaft 3-6 can be made of metal. Its function is to further limit the position of the cushion 2, prevent unnecessary displacement of the cushion 2 during use, and also enhance the structural strength of the connection between the cushion 2 and the seat plate 1.

[0042] For example, such as Figure 2 As shown, the outer wall of the seat plate 1 has a connecting cavity 4-6, and a part of the movable ball 4-5 is embedded inside the connecting cavity 4-6.

[0043] In some examples, the outer wall of the seat plate 1 has a connecting cavity 4-6. The size and shape of the connecting cavity 4-6 should match the embedded part of the movable ball 4-5 to ensure that the movable ball 4-5 can rotate smoothly in it, while also ensuring a certain fit between the two to prevent the movable ball 4-5 from shaking too much.

[0044] For example, such as Figure 2 As shown, a connecting piece 5 is provided on the upper end surface of the seat plate 1, and a seat cushion 6 is provided on the upper end surface of the connecting piece 5.

[0045] In some examples, a linkage piece 5 is provided on the upper surface of the seat plate 1. The linkage piece 5 can be made of metal and is connected to the seat plate 1 by welding or bolting. A seat cushion 6 is installed on the upper surface of the linkage piece 5. The seat cushion 6 can be made of soft sponge material and covered with breathable fabric. When the seat plate 1 rotates through the self-rotation positioning component 4, the linkage piece 5 will drive the seat cushion 6 to rotate together, ensuring the patient's comfort when adjusting their sitting posture.

[0046] For example, such as Figure 1 As shown, the inner wall of the cushion 2 is provided with an elastic band 7, the end of the elastic band 7 is connected to a waist strap 8, and the side wall of the waist strap 8 is provided with Velcro 9.

[0047] In some examples, the inner wall of the cushion 2 is provided with an elastic band 7, which can be made of elastic rubber or nylon. One end of the elastic band 7 is fixed to the cushion 2, and the end of the elastic band 7 is connected to the waist strap 8. The waist strap 8 can be made of a wider fabric to increase the contact area with the waist and improve comfort. The side wall of the waist strap 8 is provided with Velcro 9, with the male and female sides of the Velcro 9 respectively set at both ends of the waist strap 8. When using it, the patient can wrap the waist strap 8 around the waist and adjust the tightness through the Velcro 9 to make the protective device fit the body better and further enhance the fixation and protection of the waist.

[0048] For example, such as Figure 1 As shown, the bottom surface of the fixing ring 4-1 is provided with a support foot 10, and the number of support feet 10 is several, with several support feet 10 evenly arranged on the bottom surface of the fixing ring 4-1.

[0049] In some examples, the bottom surface of the fixing ring 4-1 is provided with supporting feet 10. There are several supporting feet 10, which are evenly distributed on the bottom surface of the fixing ring 4-1. The supporting feet 10 can be made of rubber or plastic, and their bottom can be designed with anti-slip texture. The function of the supporting feet 10 is to support the entire protective device, keep it at a certain distance from the ground, and provide stable support to prevent the device from sliding or tipping over during use.

[0050] For example, such as Figure 2 As shown, a hand-tightening disc 11 is provided at the end of the drive shaft 3-2, and the hand-tightening disc 11 is located outside the cushion 2.

[0051] In some examples, when the drive shaft 3-2 moves, it will move the lumbar support pad 3-4 together. Patients can adjust the position of the lumbar support pad 3-4 by rotating the hand-wrench plate 11 according to their own lumbar comfort needs, so that it fits the lumbar better and provides appropriate support.

[0052] In use, the seat board 1 serves as the basic load-bearing component of the entire device, providing a hip support platform for the patient. The backrest 2 is fixed to the side wall of the seat board 1, and its soft and elastic material contacts the back of the human body, initially constructing a support base for the back of the waist. The fixing ring 4-1 is firmly connected to the outer side wall of the seat board 1, and its bottom support foot 10 contacts the ground. The anti-slip texture increases friction and prevents the device from sliding or tipping over during use, thus providing stable bottom support for the entire device and ensuring the safety of the patient when sitting.

[0053] The core adjustment function of the lumbar support component 3 is achieved through mechanical transmission. The limiting tube 3-1 is fixed to the side wall of the backrest 2, and the internal thread machined inside meshes with the screw thread 3-3 on the outer side wall of the drive shaft 3-2 to form a threaded transmission structure. When the patient rotates the hand-cranking disc 11 located outside the backrest 2, it will drive the drive shaft 3-2 to rotate synchronously. Since the position of the limiting tube 3-1 is fixed, the drive shaft 3-2 will move along the axial direction under the action of threaded engagement, thereby driving the lumbar support pad 3-4 installed on the side wall of the drive shaft 3-2 to move synchronously. Because the lumbar support pad 3-4 corresponds to the position of the human waist, by rotating the hand-cranking disc 11, the patient can accurately adjust the front and back position of the lumbar support pad 3-4 according to their own lumbar comfort needs, so that it fits closely to the lumbar curve, providing personalized support for the waist and reducing lumbar spine pressure.

[0054] The self-rotating positioning component 4 enables multi-angle rotation adjustment of the seat plate 1. The positioning cavity 4-2 on the inner wall of the fixing ring 4-1 provides installation space for internal components. The fixing frame 4-3 is fixed inside the positioning cavity 4-2, and the fixing shaft 4-4 on it provides a rotation support point for the movable ball 4-5. The movable ball 4-5 is fitted onto the fixing shaft 4-4 and can rotate around the fixing shaft 4-4 in multiple directions. At the same time, a part of the movable ball 4-5 is embedded in the connecting cavity 4-6 on the outer wall of the seat plate 1, forming a movable connection structure. When the patient needs... When adjusting the sitting posture or body direction, the seat board 1 will rotate around the movable ball 4-5 as the fulcrum. The connecting cavity 4-6 moves synchronously with the seat board 1. The movable ball 4-5 rotates adaptively under the support of the fixed shaft 4-4, realizing the flexible rotation of the seat board 1. The connecting piece 5 connects the seat board 1 to the seat cushion 6, so that the seat cushion 6 rotates synchronously with the seat board 1, ensuring the patient's sitting posture comfort during the rotation process. At the same time, the fixed frame 4-3 and the positioning cavity 4-2 limit the movable ball 4-5 to prevent excessive rotation from affecting stability.

[0055] A limiting shaft 3-6 is set inside the limiting ring 3-5 on the outer side wall of the cushion 2. The limiting shaft 3-6 is fixedly connected to the cushion 2. The limiting ring 3-5 constrains the position of the limiting shaft 3-6, thereby further strengthening the connection between the cushion 2 and the seat plate 1, preventing unnecessary displacement of the cushion 2 during use, and enhancing the stability of the cushion 2 support. The elastic band 7 on the inner side wall of the cushion 2 has elastic elasticity. The waist strap 8 connected to its end can wrap around the waist of the human body and be quickly fastened and fixed by the Velcro 9 on the side wall. The patient can adjust the tightness of the strap according to their own waist circumference. The elastic band 7, together with the waist strap 8, tightly fixes the human waist to the cushion 2 and the waist support pad 3-4 together, avoiding relative displacement of the body when moving or the device rotates, ensuring the continuity and effectiveness of the waist support, and further strengthening the protection of the intervertebral disc.
