Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a medical traction neck brace and its method of use. Background Technology

[0002] A cervical collar is an auxiliary treatment device for cervical spondylosis. It can immobilize and protect the cervical spine, reduce nerve wear, alleviate traumatic reactions of the intervertebral joints, and help reduce tissue edema, consolidate therapeutic effects, and prevent recurrence.

[0003] However, in existing technologies, even after providing neck support, external manual massage is still required to relieve neck muscle tension. For example, Chinese patent CN114569430A discloses a reciprocating staggered tapping cervical spine massage device and its usage method. This device uses a motor to drive two tapping mechanisms, with a 180° phase difference between the cranks in the two mechanisms. This allows for alternating and reciprocating massage of both sides of the neck and shoulders with a single output power. The tapping mechanism uses a massage column to perform the first tapping massage on the shoulder near the shoulder joint, and a curved spring plate installed on the lower surface of mounting plate three to perform the second tapping massage on the cervical spine located at the shoulder, followed by a rolling massage. A spring and a spherical soft sleeve provide a dual-flexibility effect during massage. A third-flexibility effect is achieved by installing a spring between mounting plates two and three, using a curved spring plate as a contact element, and fixing a soft arc-shaped rubber plate to the bottom of the curved spring plate. This invention has a simple structure and achieves excellent neck and shoulder massage effects.

[0004] While the above solutions have the advantages mentioned above, their disadvantage is that they do not provide support for the neck and therefore cannot stretch or massage the neck. Summary of the Invention

[0009] In a preferred embodiment, the bottom of the outer surface of the neck brace traction device is provided with multiple slots, and the sliding plate is slidably embedded in the inner wall of the slots.

[0010] The technical effect of adopting the above-mentioned further solution is that the slide plate is slidably embedded in the plate groove, and the adjustable range of the slide plate is limited, thereby adjusting the stability by adjusting the position of the neck support traction device.

[0011] In a preferred embodiment, the lead screw is movably embedded inside the neck support traction device, and the sliding plate is movably embedded inside the positioning plate.

[0012] The technical effect of adopting the above-mentioned further solution is that the positioning plate provides one end fixation for the skateboard.

[0013] In a preferred embodiment, one end of the outer surface of the connecting soft rubber plate is fixedly connected to the buffer neck, and both sides of the outer surface of the headrest are movably connected to adjusting rollers, which are movably connected to the soft rubber connecting strip.

[0014] The technical effect of adopting the above-mentioned further solution is that the adjustment roller and the soft rubber connecting strip rotate to the back of the headrest before the patient's neck rests against the inside of the massage neck brace, making it convenient for the patient's head to be placed inside the massage neck brace.

[0015] In a preferred embodiment, adjustment grooves are provided on both sides of the outer surface of the headrest, and arc-shaped slides are movably embedded in the inner walls of the multiple adjustment grooves. A spring is fixedly installed on one side of the outer surface of the multiple arc-shaped slides, and a locking pin is fixedly connected to one end of the outer surface of the multiple springs.

[0016] The technical effect of adopting the above-mentioned further solution is that the setting of the adjusting roller, adjusting groove, arc-shaped slide bar, spring, and locking post can adjust the tightness of the connection between the soft rubber connecting strip and the patient's neck, thereby improving the wearing comfort.

[0017] In a preferred embodiment, the locking pins are fixedly connected to the adjusting rollers, and the outer surfaces of the multiple locking pins are provided with multiple locking teeth.

[0018] The technical effect of adopting the above-mentioned further solution is that the connecting rod set in the position of the locking post and the spring can drag and adjust the arc-shaped slide bar, thereby adjusting the connection length between the soft rubber connecting strip and the neck.

[0019] In a preferred embodiment, the inner walls of the multiple adjustment grooves are provided with multiple limiting teeth, the locking teeth are adapted to the limiting teeth, and a support roller is movably installed on one side of the outer surface of the front support.

[0020] The technical effect of adopting the above-mentioned further solution is that the cooperating locking teeth and limiting teeth can limit the adjustment of the adjusting roller.

[0021] In a preferred embodiment, a plurality of straps are fixedly installed on one side of the outer surface of the front support, and each of the straps has a strap that is movably embedded inside. One end of the outer surface of each strap is fixedly connected to a side jaw support, and the side jaw support is fixedly connected to a soft rubber connecting strip.

[0022] The technical effect of adopting the above-mentioned further solutions is that the combination of the strap strips, the binding strips, the chin rest, and the head rest provides sufficient support for the patient's neck, avoiding neck strain caused by tilting the head back.

[0023] This invention also provides a method of using a medical traction neck brace, comprising the following steps:

[0024] Step 1: With the patient back against the backrest, place the neck on the inside of the massage neck support. Rotate the soft rubber connecting strip on the adjusting roller to support the chin with the front support and the chin support on both sides, thereby increasing the support area during traction and improving traction comfort. The back of the head should be against the side of the headrest, and the bottom of the headrest should work with the front support to support the patient's head and prevent the head from tilting back. As the telescopic column at the bottom of the soft rubber plate extends and retracts, it drives the limiting plate to move up and down, thereby tractioning the patient's cervical spine and preventing neck strain caused by tilting the head back. Traction can be applied to the entire cervical spine, relieving the stimulation and compression of the nerve roots and relieving the tension in the neck muscles.

[0025] Step 2: For patients with different back shapes and body types, the sliding plate can be adjusted by rotating the screw inside the positioning plate to adjust the relative position of the backrest and the cervical traction device. The handle setting makes manual adjustment convenient. At the same time, for different head sizes, the adjustment roller can be moved by pulling. A connecting rod is set at the spring position to ensure smooth movement. By pulling the arc-shaped slide in the adjustment groove, the distance between the soft rubber connecting strip and the chin is changed, thereby adjusting. After adjusting to the appropriate size, release the handle. Under the action of the spring, the locking teeth continue to lock into the interior of the limiting teeth for fixation. Unlike existing technologies, the adjustment of the tightness and the adaptation to different spinal back shapes can be adjusted according to the patient's individual body parameters, making the cervical traction more scientific and effective.

[0026] Step 3: The front support is a fabric placed inside to support the chin. Velcro is set on one side and one end of the fabric. By setting the support roller, the overall supporting area of ​​the front support is adjusted when the double-layered fabric is pulled to adapt to chins of different widths and improve the patient's comfort.

[0027] Step 4: The massage neck support contains a reciprocating motor. Its output shaft connects to one of the rotating shafts for rotation. The rotating shaft, connecting shaft, bearing, and inner rod of the reversing device are all fixed inside the massage neck support via the bearing to improve connection stability. The reversing device transmits power through two additional small gears on the side of the side plate rotating wheel. A large gear is synchronously connected to the outside of one of the small gears, meshing with the side plate rotating wheel. This adjusts the rotation direction of the side plate rotating wheel to be opposite. The internal rotation of the side plate rotating wheel... Bearings are installed at the connection of the rotating shaft. The internal parts of multiple gears of various sizes are fixed to the outside of the rotating shaft through connecting parts. The connecting parts include a rotating shaft fixed to the gears of various sizes, and a bushing movably connected to the rotating shaft. The bushing is connected to the outside of the rotating shaft, thereby realizing the opposite movement of the side clamps, which in turn performs reciprocating clamping massage on the patient's shoulder. At the same time, the rotation of the connecting shaft drives the rotation of the eccentric ball. The eccentric ball reciprocates and squeezes the side of the neck pressure head, which in turn provides a soothing massage to the patient's cervical muscles, relieving the stimulation and compression of the nerve roots.

[0028] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0029] 1. The present invention uses a headrest with a front support to support the patient's head, preventing the head from tilting back and thus avoiding neck strain. It can provide traction to the entire cervical spine, relieving the stimulation and compression of nerve roots and soothing the muscle tension in the neck. This invention solves the problem in the prior art that there is no support for the neck and no way to stretch and massage the neck.

[0030] 2. This invention, unlike existing technologies, allows for adjustment of the tightness of the chin strap and adaptation to different spinal shapes, making cervical traction more scientific and effective by tailoring it to individual patient body parameters.

[0031] 3. The present invention adjusts the overall support area of ​​the front support when the double-layered fabric is stretched, thereby adapting to chins of different widths and improving patient comfort.

[0032] 4. This invention provides protection for the patient's neck while also providing massage to the shoulders and cervical spine. Attached Figure Description

[0042] 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.

[0043] Please see Figure 1-7This invention provides a technical solution: a medical traction neck brace, comprising: a backrest 1, a neck support traction device 2 disposed on the top of the outer surface of the backrest 1, a cushioning neck rest 3 disposed on one side of the outer surface of the neck support traction device 2, a headrest 4 fixedly installed on one side of the outer surface of the cushioning neck rest 3, soft rubber connecting strips 5 disposed on both sides of the outer surface of the headrest 4, a front support 6 disposed at one end of the outer surface of the multiple soft rubber connecting strips 5, a massage neck brace 7 fixedly installed on one side of the outer surface of the cushioning neck rest 3, multiple rotating shafts 8 disposed inside the massage neck brace 7, a connecting shaft 9 disposed inside the massage neck brace 7, multiple bearing seats 10 fixedly installed inside the massage neck brace 7, the multiple rotating shafts 8 being movably embedded inside the bearing seats 10, and the connecting shafts 9 being movably embedded inside the bearing seats 10. One end of each outer surface of the connecting shaft 9 is fixedly connected to a first bevel gear 801, and both ends of the outer surface of the connecting shaft 9 are fixedly connected to a second bevel gear 802. The first bevel gear 801 and the second bevel gear 802 mesh with each other. Side clamping wheel 11 is fixedly sleeved on the outer surface of each of the multiple rotating shafts 8, and side plate wheel 12 is movably sleeved on the outer surface of each of the multiple rotating shafts 8. Side clamping piece 1101 is fixedly installed on the outer surface of each of the multiple side clamping wheel 11, and side piece 1201 is fixedly installed on the outer surface of each of the multiple side plate wheel 12. Multiple neck pressure heads 902 are fixedly installed inside the massage neck support 7. Multiple eccentric balls 901 are fixedly sleeved on the outer surface of the connecting shaft 9. A limiting plate 201 is slidably embedded on one side of the outer surface of the neck support traction device 2. Multiple telescopic rods are provided at the bottom. A connecting soft rubber plate 202 is fixedly connected to the bottom of the outer surface of the limiting plate 201. Multiple telescopic rods are fixedly installed at the bottom of the outer surface of the connecting soft rubber plate 202. Multiple positioning plates 203 are fixedly connected to one side of the outer surface of the neck support traction device 2. After the patient leans against the backrest 1, the neck is placed inside the massage neck support 7. The soft rubber connecting strip 5 on the adjusting roller 401 is rotated to support the chin with the front support 6 and the side jaw support 604 to support the sides of the chin, thereby increasing the support area during traction and improving traction comfort. The back of the head is pressed against the side of the head support 4. The bottom of the head support 4, together with the front support 6, supports the patient's head to prevent the head from tilting back. As the telescopic column at the bottom of the connecting soft rubber plate 202 extends and retracts, the limiting plate 201 moves up and down. The device moves the patient's neck repeatedly, then applies traction to the cervical spine to prevent neck strain caused by tilting the head back. This traction can be applied to the entire cervical spine, relieving nerve root irritation and compression, and alleviating neck muscle tension. For patients with different back shapes and body types, the sliding plate 101 can be adjusted by rotating the screw 102 inside the positioning plate 203, thereby adjusting the relative position of the backrest 1 and the cervical support traction device 2. The handle 103 facilitates manual adjustment. Furthermore, for different head sizes, the adjusting roller 401 can be moved by pulling it. A connecting rod is located at the spring 404 position to ensure smooth movement. The distance between the soft rubber connecting strip 5 and the chin is changed by sliding the curved slide 403 through the adjusting groove 402.After adjusting to the appropriate size, release the grip. Under the action of spring 404, pull the locking teeth 406 to continue locking into the interior of the limiting teeth 407 for fixation. Unlike existing technologies, the adjustment of the tightness and adaptation to different spinal back shapes can be adjusted according to the patient's individual body parameters, making the cervical collar traction more scientific and effective. The front support 6 serves as the inner lining for supporting the chin. Velcro is set on one side and one end of the fabric. Through the setting of the support roller 601, the overall supporting area of ​​the front support 6 is adjusted when the double-layered fabric is pulled to adapt to different chin widths and improve the patient's comfort. The massage neck support 7 has an internal motor, which is a reciprocating motor. Its output shaft is connected to one of the rotating shafts 8 for rotation. The rotating shaft 8, connecting shaft 9, bearing seat 10, and the inner rod of the reversing device are all fixed inside the massage neck support 7 via the bearing seat 10, thus improving connection stability. The reversing device transmits power through two additional small gears on the side of the side plate rotating wheel 11. A large gear is synchronously connected to the outside of one of the small gears and meshes with the side plate rotating wheel 12, thereby adjusting the rotation direction of the side plate rotating wheel 11 and the side plate rotating wheel 12 to be opposite. The interior of the side plate rotating wheel 12 is connected to the rotating shaft 8. Bearings are installed at the connection points. Multiple gears of varying sizes are internally fixed to the outside of the rotating shaft 8 via connecting parts. The connecting parts include a rotating shaft fixed to the gears and a bushing movably connected to the rotating shaft. The bushing connects to the outside of the rotating shaft 8, thereby enabling the side clamps 1101 and 1201 to move in opposite directions, thus providing reciprocating clamping massage to the patient's shoulder. Simultaneously, the rotation of the connecting shaft 9 drives the rotation of the eccentric ball 901, which reciprocates by squeezing the side of the neck pressure head 902, thereby providing a soothing massage to the patient's cervical muscles and relieving the stimulation and compression of the nerve roots.

[0044] Please see Figure 1-7 Multiple sliding plates 101 are fixedly installed on one side of the outer surface of the backrest 1. Each sliding plate 101 has a screw rod 102 threaded inside. One end of the outer surface of each screw rod 102 is fixedly connected to a handle 103. The cooperation of the sliding plates 101, screw rod 102, and handle 103 can adjust the relative position of the backrest 1 and the neck support traction device 2 by rotating the screw rod 102.

[0045] Please see Figure 1-7 The bottom of the outer surface of the neck support traction device 2 is provided with multiple slots 204. The slide plate 101 is slidably embedded in the inner wall of the slot 204. The slide plate 101 is slidably embedded in the slot 204 to limit the adjustable range of the slide plate 101, thereby adjusting the stability of the neck support traction device 2 by adjusting its position.

[0046] Please see Figure 1-7 The lead screw 102 is movably embedded inside the neck support traction device 2, and the slide plate 101 is movably embedded inside the positioning plate 203, which provides one end fixation for the slide plate 101.

[0048] Please see Figure 1-7 The headrest 4 has adjustment grooves 402 on both sides of its outer surface. The inner walls of the adjustment grooves 402 are movably fitted with arc-shaped slide bars 403. A spring 404 is fixedly installed on one side of the outer surface of the arc-shaped slide bars 403. A locking post 405 is fixedly connected to one end of the outer surface of the spring 404. The arrangement of the adjustment roller 401, adjustment grooves 402, arc-shaped slide bars 403, springs 404, and locking posts 405 can adjust the tightness of the connection between the soft rubber connecting strip 5 and the patient's neck, thereby improving wearing comfort.

[0049] Please see Figure 1-7 The locking post 405 is fixedly connected to the adjusting roller 401. Multiple locking teeth 406 are provided on the outer surface of the multiple locking posts 405. The locking post 405, together with the connecting rod located at the position of the spring 404, can drag and adjust the arc-shaped slide bar 403, thereby adjusting the connection length between the soft rubber connecting strip 5 and the neck.

[0050] Please see Figure 1-7 Multiple adjusting grooves 402 are provided with multiple limiting teeth 407 on their inner walls. The locking teeth 406 are adapted to the limiting teeth 407. A support roller 601 is movably installed on one side of the outer surface of the front support 6. The locking teeth 406 and the limiting teeth 407 can limit the adjustment roller 401.

[0051] Please see Figure 1-7 Multiple straps 602 are fixedly installed on one side of the outer surface of the front support 6. Each strap 602 has a strap 603 movably embedded inside. One end of the outer surface of each strap 603 is fixedly connected to a side jaw support 604. The side jaw support 604 is fixedly connected to the soft rubber connecting strip 5. The straps 602, straps 603, side jaw support 604 and head support 4 work together to provide sufficient support for the patient's neck and avoid neck strain caused by tilting the head back.

[0052] Working principle

[0053] Step 1: After the patient leans back against the backrest 1, the neck is placed on the inside of the massage neck support 7. The soft rubber connecting strip 5 on the adjusting roller 401 is rotated to support the chin with the front support 6 and the side jaw support 604 to support the sides of the chin, thereby increasing the support area during traction and improving traction comfort. The back of the head is pressed against the side of the head support 4. The bottom of the head support 4, together with the front support 6, supports the patient's head to prevent the head from tilting back. As the telescopic column at the bottom of the soft rubber plate 202 extends and retracts, the limiting plate 201 moves up and down back and forth, thereby tractioning the patient's cervical spine and preventing neck strain caused by tilting the head back. Traction can be applied to the entire cervical spine to relieve the stimulation and compression of the nerve roots and soothe the tension in the neck muscles.

[0054] Step 2: For patients with different back shapes and body types, the sliding plate 101 can be adjusted by rotating the screw 102 inside the positioning plate 203, thereby adjusting the relative position of the backrest 1 and the cervical traction device 2. The handle 103 is designed for easy manual adjustment. At the same time, for different head sizes, the adjustment roller 401 can be moved by pulling it. A connecting rod is set at the position of the spring 404 to ensure smooth movement. The distance between the soft rubber connecting strip 5 and the chin is changed by pulling the arc-shaped slide 403 through the adjustment groove 402. After adjusting to the appropriate size, release the handle. Under the action of the spring 404, the locking tooth 406 is pulled to continue to lock into the interior of the limiting tooth 407 for fixation. Unlike the existing technology, the adjustment of the tightness and the adaptation to different spinal back shapes can be adjusted according to the individual body parameters of the patient, making the cervical traction more scientific and effective.

[0055] Step 3: The front support 6 is a fabric placed inside to support the chin. Velcro is set on one side and one end of the fabric. By setting the support roller 601, the overall supporting area of ​​the front support 6 is adjusted when the double-layered fabric is pulled to adapt to chins of different widths and improve the patient's comfort.

[0056] Step 4: The massage neck support 7 is equipped with a motor, which is a reciprocating motor. The output shaft is connected to one of the rotating shafts 8 for rotation. The rotating shaft 8, connecting shaft 9, bearing seat 10, and the inner rod of the reversing device are all fixed inside the massage neck support 7 through the bearing seat 10 to improve connection stability. The reversing device transmits power through two additional small gears on the side of the side plate rotating wheel 11. The small gear on one side is synchronously connected to a large gear that meshes with the side plate rotating wheel 12, thereby adjusting the rotation direction of the side plate rotating wheel 11 and the side plate rotating wheel 12 so that the rotation directions are opposite. The inner part of the side plate rotating wheel 12 is connected to the rotating wheel 12. A bearing is provided at the connection of shaft 8. The internal parts of multiple gears of various sizes are fixed to the outside of shaft 8 by connecting parts. The connecting parts include a rotating shaft fixed to the gears of various sizes and a bushing movably connected to the rotating shaft. The bushing is connected to the outside of shaft 8, thereby realizing the opposite movement of side clamp 1101 and side plate 1201, which in turn performs reciprocating clamping massage on the patient's shoulder. At the same time, the rotation of connecting shaft 9 drives the rotation of eccentric ball 901. Eccentric ball 901 reciprocates to squeeze the side of neck pressure head 902, which in turn provides a soothing massage to the patient's cervical muscles, relieving the stimulation and compression of the nerve roots.
