Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a lumbar spine protector. Background Technology

[0002] Lumbar spine braces are medical assistive devices used to help patients recover from spinal injuries. In modern life, poor lifestyle habits (such as using mobile phones in poor lying posture) often lead to lower back pain, necessitating the use of lumbar spine braces for auxiliary correction and treatment. Existing lumbar spine braces generally consist of a rigid front fixation plate and a rigid rear fixation plate. By clamping the front and rear fixation plates against the user's torso and providing a certain clamping force, they provide some fixation for the lumbar spine. However, because the front and rear fixation plates are made of medium-hardness polymer synthetic materials, they utilize slight abdominal pressure to reduce the load on the spine and provide strong fixation and stability. However, during long-term wear, this can easily lead to excessive compression of the patient's lower back and abdomen, hindering free movement and resulting in low comfort. Utility Model Content

[0025] The present invention will be further described below through specific embodiments.

[0026] like Figures 1 to 5 As shown, this embodiment provides a lumbar spine protector, including a lumbar spine fixation bracket 1 and a back strap 2.

[0027] A lumbar spine fixation brace 1 includes a front fixation plate 11 and a rear fixation plate 12 arranged front to back, side plates 13 respectively disposed on both sides of the front fixation plate 11 and the rear fixation plate 12, a detachable rear support plate 14 disposed inside the rear fixation plate 12 for supporting the lumbar spine, and a connecting assembly 15 disposed between the rear fixation plate 12 and the rear support plate 14. One end of each side plate 13 is hinged to the front fixation plate 11, and the other end is hinged to the rear fixation plate 12. In use, the front fixation plate 11 is fitted against the patient's front chest area, the side plates 13 are fitted against the patient's lumbar sides, and the rear fixation plate 12 and the rear support plate 14 are fitted against the patient's back, opposite to the front fixation plate 11. The side of the rear support plate 14 facing the patient is aligned with the patient's lumbar spine. The vertebral curvature is matched; specifically, the posterior fixation plate 12 includes multiple posterior pieces 121 arranged sequentially and spaced apart in the vertical direction, and two pressure-reducing elastic bands 122 arranged opposite each other between adjacent posterior pieces 121 to drive the deformation of the adjacent posterior pieces 121; through the cooperation between the multiple posterior pieces 121 and the two pressure-reducing elastic bands 122, when the posterior support plate 14 and the multiple posterior pieces 121 are in contact with the patient's back for a long time and the patient is in a stiff state, the patient may move his back slightly to relax his back. At this time, the adjacent posterior pieces 121 feel the pressure generated by the slight back movement. After the two pressure-reducing elastic bands 122 are subjected to force, they drive the adjacent posterior pieces 121 to sway slightly from side to side, allowing the patient to relax a little. The range of motion allows for some relaxation of the back, improving patient comfort, but only slightly. The two elastic decompression bands 122 also cause the adjacent two rear plates 121 to return to their original positions, allowing the rear fixation plate 12 to continue supporting the patient's lumbar spine and back without affecting the support of the lumbar fixation bracket 1. Furthermore, the side plate 13 includes multiple side plates 131 rotatably connected to the ends of the multiple rear plates 121 and side protective pads 132 disposed on the inner side of the side plates 131. The side plates 131 have a curved arc structure that can conform to the side of the patient's waist. Furthermore, the front fixation plate 11 includes a front plate 111 and two tension adjustment components 112 disposed on both sides of the front plate 111 and connected to the opposite side plates 13. The front protective pad 113 is located inside the front plate 111. The front plate 111 has a curved arc structure that can fit the area below the chest of the patient. When the patient carries the lumbar spine fixation bracket 1 on the back through the back strap 2, the two tension adjustment components 112 are adjusted to tighten the front fixation plate 11, the rear fixation plate 12, the side plates 13 and the rear support plate 14 and fit them tightly against the patient. This can suit patients of different body types and improve the practicality of the lumbar spine protector. Furthermore, the rear support plate 14 includes a support plate body 141 located inside the rear fixation plate 12, an arc-shaped support plate 142 movably located on the support plate body 141 that can fit against the lumbar spine, and a height adjustment component 143 located between the arc-shaped support plate 142 and the support plate body 141.The height adjustment component 143 allows for adjustment and fixation of the arc-shaped support plate 142, ensuring its conformity to the patient's lumbar curve and adaptability to different patients.

[0028] The tension adjustment assembly 112 includes a plurality of first connecting portions 114 disposed on a plurality of side pieces 131 opposite to one end of the front piece 111, a second connecting portion 115 disposed on the outside of the front piece 111 corresponding to the plurality of first connecting portions 114, and an adjustable elastic band 116 connecting the first connecting portions 114 and the opposite second connecting portions 115. Specifically, the adjustable elastic band 116 is a common adjustable band that can be shortened or extended in the prior art, and its specific structure will not be described in further detail here.

[0029] The connecting assembly 15 includes multiple fixing blocks 151 disposed on the surfaces of multiple rear pieces 121 opposite to the tray body 141, and multiple fixing fitting parts 152 disposed on the surfaces of the tray body 141 opposite to the rear fixing plate 12, which can correspond one-to-one with the multiple fixing blocks 151 and can be inserted into the fixing blocks 151; specifically, the cooperation between the multiple fixing blocks 151 and the multiple fixing fitting parts 152 facilitates the installation and removal of the rear tray 14.

[0030] The arc-shaped support plate 142 includes two positioning portions 144 extending outward from both sides and a lumbar spine protection pad 145 disposed on its outer arc surface and in contact with the patient. The outer arc surface of the arc-shaped support plate 142 conforms to the curvature of the lumbar spine. The height adjustment component 143 includes two adjusting members 146 disposed vertically opposite to each other between the two positioning portions 144 and the opposite support plate body 141. Specifically, the adjusting member 146 includes a plurality of adjusting holes 147 disposed on the support plate body 141 in the vertical direction and opposite to the positioning portions 145, a positioning hole disposed on the positioning portion 145 that can be opposite to one of the adjusting holes 147, and a positioning bolt 148 passing through the positioning hole and engaging with the adjusting hole 147.

[0031] The carrying strap 2 is mounted on the rear support plate 14 and includes a carrying strap support 21 extending upward from the top of the rear support plate 14 to contact the back, a left shoulder strap 22 and a right shoulder strap 23 mounted opposite each other on the carrying strap support 21, and a rear protective pad 24 mounted on the contact surface between the carrying strap support 21 and the patient's back.
