Description

Technical Field

[0001] This utility model relates to the field of cervical spine fixation technology, specifically a highly elastic and breathable cervical spine fixation device. Background Technology

[0002] Cervical immobilizers are new medical and health care products specifically developed for patients with cervical spondylosis. They are generally lightweight and portable, allowing patients to use them at any time and usually adjust the traction angle and force themselves. They are relatively simple to operate, safe, reliable, and painless. Cervical immobilizers are used to stabilize an injured neck and prevent secondary injury. Regular use can effectively prevent cervical spondylosis, relieve neck fatigue, and provide auxiliary traction for discomfort caused by cervical spondylosis.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN216823804U) discloses a high-elasticity, breathable cervical spine fixation device, comprising a rubber limiting structure, two-sided locking structures, a chin support structure, and a gas support structure. The rubber limiting structure has a two-sided locking structure connected to its inner middle section, and the chin support structure is connected to the inner outer wall of the two-sided locking structures. A gas support structure is fixed to the outer wall of the rubber limiting structure. The chin support structure includes a chin movable block disposed on the outer outer wall of the two-sided locking structures, and a hollow connecting column fixed to the outer outer wall of the chin movable block. This high-elasticity, breathable cervical spine fixation device utilizes the adjustment holes between the hollow connecting column fixed externally to the chin support structure and the side neck contact wall to allow it to move up and down. A rotating operating block causes the limiting block to rotate clockwise or counterclockwise, and a sliding groove allows the limiting block to engage within the locking groove, aligning the breathable mesh layer with the breathable holes, thus improving the breathability of the cervical spine fixation device.

[0004] Although the aforementioned patent utilizes the hollow linkage column fixed externally to the chin support structure and the adjustment hole of the side neck fitting wall to allow it to move up and down, the rotating operating block causes the limiting block to drive the movable column to rotate clockwise or counterclockwise, and the sliding groove is used to make the limiting block engage in the engaging groove, aligning the breathable mesh layer with the breathable holes to improve the breathability of the cervical spine fixation device, when using the high elastic breathable cervical spine fixation device, the diameter of the posterior neck fixation frame is adjusted by inflating and deflating the air bladder column, so that the high elastic breathable cervical spine fixation device fits the patient's neck more closely, thereby making the fixation of the patient's neck more stable.

[0005] However, after the airbag column is inflated, due to its elasticity, it fits too tightly against the back of the patient's neck. This not only prevents ventilation at the point where the airbag column fits against the back of the neck, but also affects the breathability of the neck fixation frame and the metabolism of the skin on the back of the patient's neck.

[0006] Therefore, this utility model provides a highly elastic and breathable cervical spine fixation device to solve the above problems. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] This invention provides a highly elastic and breathable cervical spine fixation device, which aims to solve the problems mentioned in the background art.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a highly elastic and breathable cervical spine fixation device, comprising a plastic fixation component, a Velcro slidably connected to the surface of the plastic fixation component, and a posterior cervical fixation frame fixedly connected to the plastic fixation component via the Velcro slid. A breathable mechanism is installed on the inner side of the posterior cervical fixation frame, and an adjustment mechanism is installed on the surface of the plastic fixation component.

[0011] The ventilation mechanism includes airbags arranged in a ring array and fixedly connected to the inner side of the rear neck fixation frame. Each pair of adjacent airbags is connected to a common connecting tube on opposite sides. Several airbags are connected through the connecting tube. The surface of each airbag is fixedly connected to an elastic arc-shaped plate in a path array. Each pair of adjacent airbags is connected to a common connecting mesh on opposite sides. The connecting tube is fixedly connected to the connecting mesh. One side of one of the airbags is fixedly connected to an air inlet tube that communicates with the corresponding airbag. The internal thread of the air inlet tube is connected to a sealing plug.

[0012] As a preferred technical solution of this application, two corresponding limiting plates are fixedly connected to both sides of the upper surface of the plastic fastener, and a neck brace is slidably connected to the opposite sides of the two limiting plates. The neck brace is fixedly connected to the upper surface of the plastic fastener and is made of elastic material.

[0013] As a preferred technical solution of this application, both of the limiting plates are provided with limiting grooves, and a limiting rod is inserted into the interior of both limiting grooves. The limiting rod is inserted into the interior of the neck brace, and the surface of the plastic fastener and the surface of the limiting plate are provided with several corresponding ventilation holes.

[0014] As a preferred technical solution of this application, the adjustment mechanism includes a guide plate fixedly connected to one side of the surface of the plastic fixture. Both sides of the upper surface of the guide plate are slidably connected to elastic tubes. The surface of the elastic tubes is fixedly connected to a drive tooth plate. The opposite sides of the two drive tooth plates are engaged with a drive gear.

[0015] As a preferred technical solution of this application, the adjustment mechanism further includes a rotating rod fixedly connected to one side of the drive gear, a support block rotatably sleeved on the surface of the rotating rod, one end of each of the two elastic tubes being slidably connected to the support block, the drive gear being slidably connected to the inside of the support block, and the drive gear plate being slidably connected to the inside of the support block.

[0016] As a preferred technical solution of this application, a retaining spring is fixedly connected inside the elastic tube, the support block is fixedly connected to the neck brace, and a knob is fixedly connected to one end of the rotating rod.

[0017] (III) Beneficial Effects

[0018] By incorporating a breathable structure, the plastic fastener and the posterior neck fixation frame are placed on the patient's neck using Velcro. The airbag is then inflated through the air inlet tube, resulting in a tighter fit between the posterior neck fixation frame and the patient's neck. This makes the cervical spine fixation device more stable during use. After the airbag is in contact with the patient's posterior neck, the elastic arc plate creates a gap between the airbag and the patient's posterior neck, preventing the airbag from fitting too tightly and affecting the breathability at the connection point. This ensures that the airbag can still breathe even when it is tightly fitted to the patient's posterior neck.

[0019] By adjusting the structure, the chin is supported by the limiting plate, limiting rod, and neck brace when the patient's chin is not moving, thus supporting the patient's neck. When the patient's chin needs to move, the neck brace can be moved with the patient's chin by removing the limiting rod and by adjusting its elasticity, thus preventing the neck brace from affecting the patient's eating or speaking. Furthermore, the elasticity of the neck brace, the use of plastic for the plastic fasteners, and the inclusion of an airbag improve the elasticity of the cervical spine fixation device, making it more comfortable to use.

[0020] By using a drive gear and drive tooth plate, rotating the rotating rod causes the drive gear to move the two drive tooth plates in opposite directions, which in turn causes the elastic tube to move synchronously. This allows the elastic tube to support different positions of the neck brace, thereby adjusting the elasticity of the neck brace and making it suitable for different patient conditions.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a highly elastic and breathable cervical spine fixation device, such as... Figure 1 - Figure 4 As shown, a highly elastic and breathable cervical spine fixation device includes a plastic fixation component 1, a Velcro slidably connected to the surface of the plastic fixation component 1, and a posterior cervical fixation frame 2 fixedly connected to the plastic fixation component 1 via the Velcro slid. The plastic fixation component 1 and the posterior cervical fixation frame 2 are placed on the patient's neck via the Velcro slid.

[0029] A ventilation mechanism is installed on the inner side of the posterior cervical fixation frame 2. The ventilation mechanism includes airbags 3 fixedly connected to the inner side of the posterior cervical fixation frame 2 in a ring array. A connecting tube 4 is fixedly connected to the opposite sides of every two adjacent airbags 3. Several airbags 3 are connected through the connecting tube 4. An elastic arc plate 5 is fixedly connected to the surface of the airbag 3 in a path array. A ventilation net 6 is fixedly connected to the opposite sides of every two adjacent airbags 3. The connecting tube 4 is fixedly connected to the ventilation net 6. An air inlet tube 7 is fixedly connected to one side of one of the airbags 3 and is connected to the corresponding airbag 3. The corresponding airbag 3 is inflated through the air inlet tube 7. Through the setting of the connecting tube 4, several airbags 3 are inflated, causing the airbags 3 to deform and drive the elastic arc plate 5 to fit against the back of the patient's neck, supporting the posterior cervical fixation frame 2 and the back of the patient's neck. This not only makes the cervical fixation device more stable when in use, but also ensures that there is a gap between the airbags 3 and the back of the neck when the airbags 3 fit against the back of the patient's neck.

[0030] The air intake pipe 7 has a sealing plug connected to its internal thread. Two corresponding limiting plates 8 are fixedly connected to both sides of the upper surface of the plastic fixing part 1. The neck support 9 is slidably connected to the opposite sides of the two limiting plates 8. The neck support 9 is fixedly connected to the upper surface of the plastic fixing part 1. The neck support 9 is made of elastic material. The surfaces of the two limiting plates 8 are provided with limiting grooves 10. The two limiting grooves 10 are inserted into the interior of the two limiting rods 11. The limiting rod 11 is inserted into the interior of the neck support 9. Since the neck support 9 supports the patient's chin, it is inconvenient for the patient to use the chin when the cervical fixation device is in use. Therefore, when the patient uses the chin, the limiting rod 11 can be pulled out, so that the limiting rod 11 no longer limits the neck support 9, and the neck support 9 can move between the two limiting plates 8.

[0031] The combined structure of the neck brace 9, limiting plate 8, and limiting rod 11 plays a unique and practical role in actual use. When the patient wears the cervical spine fixation device normally, the neck brace 9, with its elastic support performance, provides comfortable and stable support for the patient's chin, helping to maintain the cervical spine in the correct physiological curvature and effectively reducing the burden on the neck muscles. However, when the patient needs to perform chin movements (such as eating, speaking, and other daily activities), the fixed support of the neck brace 9 may cause inconvenience. At this time, simply pull out the limiting rod 11 to release its constraint on the neck brace 9, allowing the neck brace 9 to move flexibly between the two limiting plates 8. According to actual user feedback and testing, with this design, the degree of restriction on chin movement is significantly reduced when the patient wears the cervical spine fixation device, and the comfort during daily eating and communication is significantly improved, basically meeting normal life needs and greatly enhancing the practicality of the product and the user experience.

[0032] Both the surface of the plastic fastener 1 and the surface of the limiting plate 8 are provided with several corresponding ventilation holes. The ventilation holes improve the breathability when the cervical spine fixation device is used. An adjustment mechanism is installed on the surface of the plastic fastener 1. The adjustment mechanism includes a guide plate 12 fixedly connected to one side of the surface of the plastic fastener 1. Both sides of the upper surface of the guide plate 12 are slidably connected to elastic tubes 13. A retaining spring 18 is fixedly connected inside the elastic tube 13. A drive tooth plate 14 is fixedly connected to the surface of the elastic tube 13. The opposite sides of the two drive tooth plates 14 mesh with a drive gear 15. The adjustment mechanism also includes a rotating rod 16 fixedly connected to one side of the drive gear 15. A knob is fixedly connected to one end of the rotating rod 16. The knob makes it easier to rotate the rotating rod 16.

[0033] The ingenious design of the adjustment mechanism provides excellent adjustability for the cervical spine fixation device. When the user turns the knob, the knob drives the rotating rod 16 to rotate easily, which in turn drives the connected drive gear 15 to rotate synchronously. Due to the meshing relationship between the drive gear 15 and the drive tooth plate 14, the rotation of the drive gear 15 causes the two drive tooth plates 14 to move in opposite directions, thereby causing the connected elastic tube 13 to slide on the guide plate 12 accordingly. During this process, the retaining spring 18 adjusts its elastic force in a timely manner according to the position change of the elastic tube 13, so that the elastic tube 13 can provide different levels of support for the neck brace and other related components. Through this adjustment mechanism, users can easily and conveniently adjust the support strength and comfort of the cervical spine fixation device according to their actual needs, meeting the personalized needs of different individuals in different usage scenarios, greatly enhancing the applicability and practicality of the cervical spine fixation device.

[0034] A support block 17 is rotatably sleeved on the surface of the rotating rod 16. The support block 17 is fixedly connected to the neck support 9. One end of each of the two elastic tubes 13 is slidably connected to the support block 17. The drive gear 15 is slidably connected inside the support block 17. By rotating the rotating rod 16, the drive gear 15 rotates, causing the two drive tooth plates 14 to move in opposite directions, which in turn drives the two elastic tubes 13 to move. This allows the elastic tubes 13 to support the neck support 9 at different positions, thereby changing the elasticity of the neck support 9 and making it suitable for different needs. The drive tooth plates 14 are slidably connected inside the support block 17.

[0035] Specifically, when using this high-elasticity breathable cervical spine fixation device: the plastic fastener 1 is attached to the posterior cervical fixation frame 2 using Velcro and placed on the patient's neck. The air inlet tube 7 inflates the corresponding airbags 3. Through the connecting tube 4, several airbags 3 are inflated, causing them to deform and move the elastic arc plate 5 to fit against the back of the patient's neck, supporting the posterior cervical fixation frame 2 and the patient's back of the neck. This not only makes the cervical spine fixation device more stable during use, but also prevents the airbags 3 from fitting directly against the back of the patient's neck, creating a gap between the airbags 3 and the back of the neck. This avoids the airbags 3 fitting directly against the back of the patient's neck, which would affect the breathability of the cervical spine fixation device and thus the metabolism of the skin on the back of the patient's neck.

[0036] Because the cervical collar 9 supports the patient's chin, it makes it inconvenient for the patient to use the cervical fixation device. Therefore, when the patient is using the cervical collar, the limiting rod 11 can be pulled out, so that the limiting rod 11 no longer limits the cervical collar 9. This allows the cervical collar 9 to move between the two limiting plates 8. And through the elastic setting of the cervical collar 9, it can still provide some support for the chin, making it more convenient for the patient to move when using the cervical fixation device.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
