Description

Technical Field

[0001] This utility model belongs to the field of neck brace technology, specifically relating to a pressure-reducing neck brace. Background Technology

[0002] Neck braces, as common medical support devices, are widely used in the rehabilitation of patients with cervical spondylosis or neck injuries. Their main function is to support the weight of the head and restrict the range of motion of the neck, thereby reducing the burden on the cervical spine and promoting recovery. Existing neck brace devices typically use a fixed structure to provide wrap-around support for the neck. Their structure is relatively simple, and they are generally used by securing the front and rear panels with straps. However, under long-term wear, this type of structure often has the following problems: First, most existing neck braces use rigid materials for support and lack pressure-reducing and cushioning structures. This makes it easy to compress the soft tissues of the neck during wear, affecting local blood circulation and causing discomfort or skin indentations. This is not conducive to long-term use and the continuity of rehabilitation treatment for patients.

[0003] Secondly, traditional neck braces are typically enclosed structures, lacking effective ventilation and regulation during use. This can easily lead to localized heat and moisture buildup, especially in hot summer months or when patients sweat excessively, causing skin allergies, itching, and other problems, severely impacting the wearing experience. In winter, the lack of a sealed structure makes it difficult to provide insulation, further affecting patient comfort.

[0004] In addition, some ventilation control structures in the existing technology have problems such as cumbersome adjustment operation and difficulty in positioning. In particular, the structure may become loose or not be fixed in place during the adjustment process, which often makes it difficult for users to accurately control the opening and closing of the ventilation and affects the realization of the function. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a pressure-reducing neck brace that can achieve convenient and effective ventilation and sealing adjustment functions, and ensure that each adjustment structure can be reliably locked after operation to prevent displacement, thereby improving wearing comfort and functional flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure-reducing neck brace, comprising a front guard plate and a rear guard plate, wherein one end of the front guard plate and the rear guard plate are hinged to each other, and the surfaces of the front guard plate and the rear guard plate are uniformly provided with first ventilation holes; The inner walls of the front and rear guard plates are uniformly equipped with pressure-reducing cotton strips, and multiple pressure-reducing cotton strips are staggered with multiple rows of the first ventilation holes. The pressure-reducing cotton strips are used to reduce pressure on the neck. Both the front and rear guard plates have concave surfaces on their outer surfaces, and multiple first vent holes are located inside the concave surfaces. An arc-shaped sliding plate is slidably installed inside the concave surfaces, and second vent holes are evenly distributed on the surface of the arc-shaped sliding plate. Ventilation is controlled by controlling the overlap between the second vent holes and the first vent holes.

[0007] Furthermore, a chin rest is provided on the upper surface of the front guard plate, and a headrest is provided on the upper surface of the rear guard plate.

[0008] Furthermore, the concave surface has grooves on both the upper and lower inner walls, and the arc-shaped sliding plate has ridges on both the upper and lower surfaces, with the ridges sliding inside the grooves.

[0009] Furthermore, both the front and rear guard plates have two outwardly extending plates on their outer surfaces, with the two extending plates positioned on the upper and lower surfaces of the concave surface, respectively, and two positioning holes formed on the surface of each extending plate.

[0010] Furthermore, a boss is provided on the outer side of the arc-shaped sliding plate, and a positioning bolt is symmetrically slidably installed inside the boss, with the end of the positioning bolt matching the positioning hole.

[0011] Furthermore, a track groove is provided at the center of the outer surface of the arc-shaped slide plate, and a lever is vertically provided at one end of the positioning bolts that are close to each other. The two levers pass through the track groove respectively, and a spring is provided at the center of the inside of the arc-shaped slide plate. The springs apply an outward pushing force to the two positioning bolts respectively.

[0012] Furthermore, both the front and rear guard plates are provided with Velcro straps at their other ends.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By setting pressure-reducing cotton strips on the inner walls of the front and rear panels, the neck brace can provide flexible cushioning support to the neck during use, evenly distributing the pressure on the neck. This effectively alleviates problems such as obstructed blood circulation and skin indentations caused by the hard support surface and strong local pressure of traditional neck braces, improving wearing comfort and safety, and meeting the needs of long-term wear.

[0014] By evenly distributing first ventilation holes on the surfaces of the front and rear guard plates, and sliding an arc-shaped sliding plate on the concave surface of the outer side, with second ventilation holes on the surface of the arc-shaped sliding plate, and adjusting the alignment with the first ventilation holes, the opening and closing of the ventilation openings can be controlled. This allows the neck brace to switch between ventilation and sealing according to the ambient temperature and the user's needs, maintaining breathability in hot seasons and improving heat insulation performance in cold seasons, thus solving the problems of fixed structure, poor ventilation, and discomfort from temperature changes in traditional neck braces.

[0015] By setting a groove in the concave surface and setting a convex strip on the surface of the arc-shaped slide plate that matches the groove, the arc-shaped slide plate always maintains track guidance during sliding, avoiding sliding deviation or falling off, ensuring the stability and reliability of the ventilation adjustment structure during long-term use, and effectively improving the service life of the whole machine and the user's operating experience.

[0016] By setting positioning holes in the extension plate and cooperating with the locking mechanism consisting of positioning bolts, actuating rods, and internal springs in the outer boss structure of the arc-shaped sliding plate, the sliding plate can be automatically positioned and locked after adjustment. During adjustment, the limit can be released by moving the actuating rod. The structure is easy to operate and accurately positioned, solving the problems of difficult positioning or loose sliding in existing adjustment structures, and enhancing the practicality and control precision of the adjustment function.

[0017] By setting Velcro at the non-hinged ends of the front and rear guards, the neck brace forms a flexible and adjustable closed structure. The fit can be flexibly adjusted according to different neck circumferences, simplifying the wearing process, improving adaptability, meeting the needs of different people, and overcoming the problems of cumbersome or limited adaptability of traditional fixing methods.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] refer to Figures 1-6 As shown, a pressure-reducing neck brace includes a front guard plate 1 and a rear guard plate 2, which are hinged together at one end. First ventilation holes 5 are evenly distributed on the surfaces of the front guard plate 1 and the rear guard plate 2. The hinged structure of the front guard plate 1 and the rear guard plate 2 provides a wraparound coverage of the neck, facilitating wearing and securing. The main structure of the front guard plate 1 and the rear guard plate 2 is made of a lightweight material with a certain degree of rigidity to ensure stable support for the neck while reducing overall weight and ease of wear. Multiple first ventilation holes 5 are symmetrically arranged on the outer surfaces of the front guard plate 1 and the rear guard plate 2, effectively improving ventilation in the neck area during wear and avoiding the stuffy and damp problems associated with traditional neck braces. The first ventilation holes 5 not only help with heat dissipation and ventilation but also work in conjunction with the subsequent sliding ventilation structure to achieve an opening and closing adjustment function.

[0022] refer to Figures 1-6 As shown, pressure-relieving cotton strips 4 are evenly installed on the inner walls of the front guard plate 1 and the rear guard plate 2. Multiple pressure-relieving cotton strips 4 are staggered with multiple rows of first ventilation holes 5. The pressure-relieving cotton strips 4 are used to reduce pressure on the neck. The pressure-relieving cotton strips 4 are cushioning materials with elasticity, which can effectively disperse local pressure while maintaining the ability to support deformation, reduce the pressure on the neck skin and soft tissues of the front guard plate 1 and the rear guard plate 2 during long-term wear, and prevent the occurrence of blood circulation obstruction. The pressure-relieving cotton strips 4 are staggered with the first ventilation holes 5, which maintains local flexible contact and ensures unobstructed air circulation channels, fully responding to the demand for dual functions of pressure relief and ventilation proposed in the background art.

[0023] refer to Figures 1-6 As shown, both the front guard plate 1 and the rear guard plate 2 have concave surfaces 6 on their outer surfaces. Multiple first vent holes 5 are located inside the concave surfaces 6. An arc-shaped sliding plate 8 is slidably installed inside the concave surfaces 6. Second vent holes 82 are evenly distributed on the surface of the arc-shaped sliding plate 8. Ventilation is controlled by adjusting the overlap between the second vent holes 82 and the first vent holes 5. The concave surfaces 6 serve as the mounting base for the sliding groove structure, providing a stable movement trajectory for the arc-shaped sliding plate 8. The arc-shaped sliding plate 8 has a semi-circular arc structure, and the opening and closing of the first vent holes 5 can be adjusted by sliding, thereby meeting the different needs of winter insulation and summer ventilation. The number and layout of the second vent holes 82 on the arc-shaped sliding plate 8 match the first vent holes 5, ensuring alignment accuracy and flow effect during ventilation adjustment. This structure effectively avoids wear and structural loosening problems caused by repeated opening and closing in traditional structures by sliding adjustment rather than opening and sealing.

[0024] refer to Figures 1-3 As shown, a chin support 11 is provided on the upper surface of the front guard plate 1, and a head support plate 21 is provided on the upper surface of the rear guard plate 2. The chin support 11 is a protruding structure on the upper surface of the front guard plate 1, used to support the wearer's chin and prevent the neck from shifting due to instability caused by being suspended. The head support plate 21 is an extension structure on the upper part of the rear guard plate 2, which plays a stabilizing and supporting role on the back of the head. Together with the overall structure, it restrains the position of the head, effectively improves the support and fit performance of the neck brace, and avoids affecting the rehabilitation effect due to loosening of the neck brace.

[0025] refer to Figure 4 and Figure 5 As shown, grooves 61 are provided on both the upper and lower inner walls of the concave surface 6, and ridges 81 are provided on both the upper and lower surfaces of the arc-shaped sliding plate 8. The ridges 81 slide inside the grooves 61. The grooves 61 serve as guide and limiting structures for the arc-shaped sliding plate 8, and are embedded in the upper and lower edges of the concave surface 6 to prevent the arc-shaped sliding plate 8 from shifting laterally or falling off during sliding. The ridges 81 are raised structures that match the shape of the grooves 61. Through sliding contact with the grooves 61, the arc-shaped sliding plate 8 can be ensured to run smoothly within a preset trajectory, avoiding structural loosening or jamming. The guiding and limiting mechanism of this structure effectively ensures the long-term stable operation of the ventilation regulating device.

[0026] refer to Figure 3 As shown, two extension plates 7 are provided outward on the outer surfaces of both the front guard plate 1 and the rear guard plate 2. The two extension plates 7 are respectively placed on the upper and lower surfaces of the concave surface 6. Two positioning holes 71 are opened on the surface of the extension plates 7. The extension plates 7 serve as the structural base for fixing the position of the arc-shaped sliding plate 8. Their positions correspond to the structure of the concave surface 6, and they provide sliding locking points through the positioning holes 71. The positioning holes 71 are evenly distributed on the surface of the extension plates 7. They cooperate with the positioning bolts 9 in the subsequent structure to achieve rapid positioning and fixing of the arc-shaped sliding plate 8 between the open and closed positions, solving the problem that the adjustment structure in the existing neck brace is not easy to position.

[0027] refer to Figure 3 and Figure 4 As shown, a boss 83 is provided on the outer side of the arc-shaped slide plate 8. A positioning bolt 9 is symmetrically slidably installed inside the boss 83. The end of the positioning bolt 9 is adapted to the positioning hole 71. The boss 83 is the external control unit structure of the arc-shaped slide plate 8, forming a cavity to accommodate the positioning bolt 9, ensuring that the bolt can slide within the limited track. The positioning bolt 9 is an elastic reset component, and its end diameter matches the positioning hole 71. By extending into or out of the positioning hole, the arc-shaped slide plate 8 can be locked or unlocked. This structure can automatically return to its original position and lock after the wearer completes the ventilation adjustment operation, preventing the ventilation state from being changed due to accidental sliding.

[0028] refer to Figure 5 and Figure 6As shown, a track groove 84 is provided at the center of the outer surface of the arc-shaped slide plate 8. A lever 91 is vertically arranged at one end of the positioning bolts 9 that are close to each other. The two levers 91 pass through the track groove 84 respectively. A spring 10 is provided at the center of the arc-shaped slide plate 8. The spring 10 applies an outward pushing force to the two positioning bolts 9 respectively. The track groove 84 passes through the center of the boss 83 and is used to guide the lever 91 to slide vertically, so as to realize the synchronous contraction action of the positioning bolts 9 under external force. The lever 91 serves as a control end extension structure, which allows the user to directly operate it from the outside to release the locked state. The spring 10 is located between the two positioning bolts 9 and realizes the outward push of the bolts through the central symmetrical thrust, which enhances the engagement stability of the bolts and the positioning hole 71. This structure improves the convenience and reliability of adjustment and control through the coordinated linkage of lever, bolt and spring.

[0029] refer to Figure 1 As shown, both the front guard plate 1 and the rear guard plate 2 are provided with Velcro 3 at their other ends. Velcro 3 serves as the end connector between the front guard plate 1 and the rear guard plate 2, achieving the closure and fixation of the overall structure through mutual adhesion. Velcro 3 consists of a fabric side and a hook and loop side, allowing for multiple opening and closing, facilitating user adjustment according to neck circumference size. Its adjustability also provides good fit for users of different body types. This structure simplifies the wearing process, improves the practicality of the neck brace, and meets the improvement requirements for the operability and adaptability of the fixation structure in the background art.

[0030] The working principle of this utility model is as follows: When in use, the front guard plate 1 and the rear guard plate 2 are placed at the front and back of the patient's neck, respectively. Then, the front guard plate 1 and the rear guard plate 2 are fixed by the Velcro 3 to support the neck. The pressure-reducing cotton strips 4 inside the front guard plate 1 and the rear guard plate 2 can reduce the pressure on the neck and ensure blood circulation in the neck. Due to the presence of the spring 10, an outward pushing force is applied to the two positioning bolts 9, so that the end of the positioning bolt 9 cooperates with the positioning hole 71 at the corresponding position to ensure the fixed position of the arc-shaped slide plate 8. By adjusting the position of the arc-shaped slide plate 8, the overlap between the second ventilation hole 82 and the first ventilation hole 5 can be controlled. When they overlap, ventilation is achieved. Conversely, in winter, the position of the arc-shaped slide plate 8 can be adjusted to make the second ventilation hole 82 and the first ventilation hole 5 misaligned, thereby sealing and achieving the purpose of heat preservation. The arc-shaped slide plate 8 slides inside the concave surface 6, and the convex strip 81 is placed inside the slide groove 61 to prevent the arc-shaped slide plate 8 from falling off. The two positioning holes 71 on the extension plate 7 correspond to the complete opening and complete sealing of the first vent hole 5, respectively. During adjustment, the two levers 91 are pressed externally to bring them closer together, so that the two positioning bolts 9 are brought closer together, thereby losing their limitation with the positioning holes 71. After adjustment, they are fixed again.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
