Description

Technical Field

[0001] This invention relates to the field of neck protection devices, specifically a portable neck support and protective fixation device. Background Technology

[0002] For patients with neck injuries, medical devices such as neck braces or supports are needed to relatively fix the neck, reduce the range of motion of the neck, prevent excessive head movement that could lead to cervical spine dislocation, and reduce disability rates. See Chinese Patent Publication No. CN2853016Y, which discloses a portable multifunctional external fixation bracket for neck injuries, specifically disclosing the following technical solution: It includes two halves, front and rear, each half comprising a neck brace, a chest-back clamp, and a support traction device. The support traction device is located between the neck brace and the chest-back clamp, with its two ends hinged to the neck brace and chest-back clamp respectively. The support traction device consists of upper and lower support bodies. The lower support body contains a threaded push rod for pushing the upper support body. The threaded push rod is controlled by a pressure nut, and a spring is provided between the threaded push rod and the upper support body. A sliding column is also provided between the upper and lower support bodies.

[0003] However, the applicant argues that the aforementioned existing technologies, primarily designed for clinical use, employ fixed structures, which limit portability. Furthermore, their monolithic structures hinder effective assembly and reduce storage space requirements, resulting in low flexibility. Therefore, the applicant believes there is still room for improvement to enhance portability and flexibility. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a portable neck support and protective fixation device, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a portable neck support and protective fixing device, comprising a connecting strap and several support units, wherein the two ends of the connecting strap are provided with locking components and are connected by the locking components, and the connecting strap is fixed with strap body connecting parts at intervals along the length direction, and the upper and lower sides of the strap body connecting parts are respectively provided with connecting slots. Each of the support units includes a box support base, on the back of which L-shaped strap snap-fit ​​grooves are symmetrically arranged, and the two sides of the strap snap-fit ​​grooves (which together form a snap-fit ​​cavity) can be detachably snapped into and assembled with the connecting groove of the strap connection part. Each box support base is provided with an upper elastic support and a lower elastic support at the top and bottom respectively. An upper telescopic connection is provided between two adjacent upper elastic support and a lower telescopic connection is provided between two adjacent lower elastic support. Beneficial effects

[0006] Compared with existing technologies, it has the following advantages: The present invention features an L-shaped belt snap-fit ​​groove integrally formed on the back of the support unit, symmetrically arranged. The two sets of belt snap-fit ​​grooves together form a snap-fit ​​cavity. During assembly, the belt connecting part is vertically snapped into the snap-fit ​​cavity, so that the connecting groove and the belt snap-fit ​​groove are in concave-convex limiting fit, realizing quick and detachable assembly of the support unit and the connecting belt. During disassembly, the support unit can be separated by lifting it upwards, and all support units can be removed and stored separately. This invention features two functionally distinct elastic support structures. The upper elastic support is a hollow, inflatable structure, with its expansion thickness freely adjustable via a concealed air inlet. The lower elastic support is made of solid silicone, providing stable support to the base of the neck and lower jaw, limiting excessive head flexion. It also incorporates upper and lower telescopic connecting sections with a 10-35mm telescopic range, adapting to the assembly spacing of adjacent support units to form a complete support ring around the neck, preventing support gaps or localized suspension. The support unit of this invention is equipped with symmetrical guide rods and a magnetic attraction buffer structure with the same poles repelling each other. It can flexibly absorb and buffer the impact of head movement and automatically reset, effectively avoiding the risk of secondary cervical spine injury caused by rigid brackets. The inner and outer pads are quickly disassembled and assembled through the plug-in structure. All parts can be cleaned and sterilized at high temperature individually, eliminating cleaning dead corners of the integrated neck brace and reducing the risk of cross-infection in clinical settings. This invention features a simple assembly structure using snap-fit, buckle, and Velcro, requiring no professional training. Ordinary bystanders can quickly and accurately position and securely fix the neck in a neutral position at the accident scene and before medical personnel arrive, greatly expanding the applicable scenarios of the device and improving the universality of pre-hospital emergency treatment. Wearing and disassembling require no tools, and the operation process is simple. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0018] like Figures 1-6 and Figure 9 As shown, this embodiment provides a portable neck support and protective fixation device, including a connecting strap 1 and several support units 6. The connecting strap 1 is a ring-shaped strap made of medical breathable elastic fabric, with locking components at both ends. The locking components are widened Velcro to fit people with different neck circumferences. The connecting strap 1 is stitched and fixed with several strap connecting parts 8 at intervals along its length. The strap connecting parts 8 are flexible rigid plastic sheets, and connecting slots 22 are opened on the upper and lower sides of the strap connecting parts 8 respectively. Each support unit 6 includes a box support base with symmetrically arranged L-shaped strap snap-fit ​​grooves 7 integrally formed on the back. The two sets of strap snap-fit ​​grooves 7 together form a snap-fit ​​cavity. During assembly, the strap connecting part 8 is vertically inserted into the snap-fit ​​cavity, so that the connecting groove 22 and the strap snap-fit ​​groove 7 are in a concave-convex limiting fit, realizing quick and detachable assembly and disassembly of the support unit 6 and the connecting strap 1. During disassembly, the support unit 6 can be separated by lifting it upwards, and all support units 6 can be removed and stored separately. Each box support base is provided with an upper elastic support 5 and a lower elastic support 9 at its top and bottom, respectively. The upper elastic support 5 is a hollow medical silicone air tube, and the lower elastic support 9 is a solid medical silicone elastic strip. An upper telescopic connecting part 4 is provided between two adjacent upper elastic support parts 5. The ends of the upper elastic support parts 5 are sealed together by the upper telescopic connecting tube 4. A lower telescopic connecting part 10 is provided between two adjacent lower elastic support parts 9. The ends of the lower elastic support parts 9 are connected by the lower telescopic connecting tube 10. Both the upper telescopic connecting part 4 and the lower telescopic connecting part 10 are corrugated telescopic tubes with open ends. The telescopic adjustment stroke is controlled between 10mm and 35mm, which can adapt to the change in the spacing between adjacent support units 6. An air inlet is provided on the side wall of any one of the upper elastic support parts 5. The air inlet is housed in the tube of the upper telescopic connecting part 4. An external air inlet tool can be connected to inflate or deflate the tube to adjust the expansion thickness of the upper elastic support tube 5 and adapt to different neck circumferences. The outer side of the support unit 6 is covered with an outer pad 2, and the inner side is fitted with an inner pad 3. Both the outer pad 2 and the inner pad 3 are made of medical breathable and skin-friendly fabric. Multiple plug sleeves 12 are integrally fixed on the inner side of the outer pad 2, and plug rods 11 are correspondingly fixed on the outer side of the inner pad 3. The box support base and the outer shell 21 are provided with coaxial connection holes at corresponding positions. A through-type box internal connecting tube 15 is fixed inside the box support base. The two ends of the box internal connecting tube 15 are respectively connected to the connection holes on both sides. The box internal connecting tube 15 is used to support the outer shell 21 and form a through plug channel. When assembling the pad, the plug sleeve 12 passes through the connection hole of the outer shell 21 and the box internal connecting tube 15 in sequence and extends into the inner side of the box. Then, the plug rod 11 of the inner pad 3 is inserted into the plug sleeve 12 with an interference fit to complete the locking.

[0019] The inner liner 3 and the outer liner 2 are equipped with Velcro at both ends. The inner liner 3 is attached to the outer liner 2 after passing around the upper elastic support part 5 and the lower elastic support part 9. The liner can be removed as a whole, washed and disinfected at high temperature to avoid cross-infection in the hospital.

[0020] In this embodiment, when wearing the garment, multiple support units 6 are snapped onto the connecting part of the strap 1, the inner and outer pads 2 and 3 are installed, and the connecting strap 1 is fastened with Velcro at both ends around the neck. The inflation amount of the upper elastic support 5 is adjusted through the air inlet nozzle, and the working inflation pressure of the upper elastic support tube 5 is controlled between 0.02MPa and 0.05MPa, so that the elastic components fit the side and under the neck to complete the limiting support. When storing the garment, the Velcro is torn off to separate the inner pad 3, the plug sleeve 12 is pulled out and the outer pad 2 is removed, and all support units 6 are pulled upward to remove them from the connecting strap 1. The buckles at both ends of the upper telescopic connecting part 4 and the lower telescopic connecting part 10 are disassembled to separate the elastic components. All parts are laid flat and stacked for easy carrying in a bag. Example 2

[0021] like Figure 7 and Figure 8 As shown, this embodiment optimizes and upgrades the internal structure of the modular support unit 6 based on embodiment 1, while the remaining external structure is completely consistent with embodiment 1. Specifically: The box support is a hollow closed box with an opening at the front end. The opening can be detached and sealed with the outer shell 21. The box support has a horizontally fixed partition 17 inside, which divides the inner cavity of the box into two independent chambers. Two telescopic sleeves 18 are vertically fixed in the center of the partition 17. Each telescopic sleeve 18 has a slidingly assembled plate adjustment rod 20 inside, and the top of the plate adjustment rod 20 protrudes through the top surface of the box support seat. The top of the plate adjustment rod 20 is connected to an arc-shaped upper movable plate 13, and the two arc-shaped upper movable plates 13 jointly support the corresponding upper elastic support part 5. With the central telescopic sleeve 18 as the reference, two plate guide rods 19 are symmetrically and vertically fixed on the left and right sides above the partition 17. The top of the plate guide rods 19 extends upward through the top surface of the box and slides into the arc-shaped upper movable plate 13. The two plate guide rods 19 form a double-sided limiting slide rail, which restricts the upper movable plate 13 to only rise and fall in the vertical direction, avoiding unilateral force tilting and sliding jamming, and ensuring that the support height on both sides of the neck is uniform. Below the partition 17, two lower fixing plates 14 are symmetrically fixed to the bottom wall of the box support base by multiple fixing plate connecting rods 16. The two lower fixing plates 14 correspond one-to-one with the arc-shaped upper movable plate 13, and together support the corresponding lower elastic support part 9.

[0022] A first strong magnetic block is fixed at the bottom of the inner cavity of the telescopic sleeve 18, and a second strong magnetic block is fixed at the bottom of the plate adjusting rod 20. Both the first and second strong magnetic blocks are neodymium iron boron permanent magnets. The first and second strong magnetic blocks, with the same poles, form a continuous repulsive force, and the static repulsive force range between them is 8N-12N. Under normal conditions without external force, the magnetic repulsive force continuously pushes the plate adjusting rod 20 upward, causing the arc-shaped upper movable plate 13 to extend outward, opening the upper elastic support part 5 to fit against both sides of the neck, achieving stable positioning. When the patient's head tilts forward and lateral pressure generates squeezing force, the upper elastic support part 5 drives the upper movable plate 13 to press down, and the plate adjusting rod 20 overcomes the magnetic repulsive force and slides downward along the telescopic sleeve 18, relying on the magnetic repulsive force to achieve flexible buffering and prevent the cervical spine from being subjected to hard impact. After the external force disappears, the repulsive force of the two magnetic blocks automatically pushes the plate adjusting rod 20 upward to reset, continuously maintaining the neck support and positioning effect.
