Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a head and neck shock absorption and fixation device. Background Technology

[0002] The head and neck shock absorption and fixation device is a new type of medical and health care product developed for patients with traumatic brain injury. Its main function is to stabilize the injured head and neck. After a traumatic brain injury, patients need to wear this device for half a month or longer to recover from the injury.

[0003] When in use, this head and neck shock absorption and fixation device can transfer the weight of the head to the shoulders, reducing the stress on the neck and thus preventing secondary injury. It can also prevent the head and neck from floating up and down when the patient sits up or down.

[0004] However, when patients actually wear the head and neck shock absorption and fixation device, they need to wear it for a long time. The weight of the head and neck will be transmitted to the patient's shoulders, causing the shoulders to be under pressure for a long time. Over time, the shoulders cannot be properly relaxed, making them prone to soreness, which is not conducive to the long-term wearing of the head and neck shock absorption and fixation device. Summary of the Invention

[0005] The purpose of this application is to provide a head and neck shock absorption and fixation device to address the problem that when worn for extended periods, the weight of the head and neck is transmitted to the patient's shoulders for a long time, causing the shoulders to be under pressure for a long time and resulting in shoulder pain.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A head and neck shock absorption and fixation device includes a first neck fixation frame and a second neck fixation frame. Shoulder support plates are fixed to the opposite sides of both the first and second neck fixation frames. The bottom of each shoulder support plate has an arc-shaped groove, and the top of each shoulder support plate has a first sliding groove. Massage rollers are installed within the first sliding grooves of both shoulder support plates. A moving mechanism is provided within the sliding grooves of each shoulder support plate to allow the massage rollers to move within the first sliding grooves. A first head fixation frame and a second head fixation frame are symmetrically arranged on the top of the first neck fixation frame. Velcro is fixed to both ends of the first neck fixation frame and the first head fixation frame. Fixing rings are fixed to both ends of the second neck fixation frame and the second head fixation frame. A pre-fixing mechanism is provided on one side of the first neck fixation frame for pre-fixing the first and second neck fixation frames. The Velcro is adapted to the fixing rings. A sliding mechanism is provided on the top of the shoulder support plates for allowing the first and second head fixation frames to slide up and down.

[0008] By adopting the above technical solution, when using the head and neck shock absorption and fixation device, firstly, the first and second neck fixation frames are aligned with the patient's neck. Then, the height of the first and second head fixation frames is adjusted by the sliding mechanism. Then, the first and second neck fixation frames are pre-fixed by the pre-fixing mechanism. Subsequently, the device is fixed by passing Velcro through the fixing ring. At the same time, the arc-shaped groove can fit with the patient's shoulder. The massage rollers are moved in the first sliding groove by the moving mechanism.

[0009] Furthermore, the moving mechanism includes connecting rods symmetrically rotatably connected to both sides of the massage roller, connecting frames are fixed to the surfaces of the two connecting rods, a pressing block is fixed to the top of the connecting frames, a second slider is fixed to the side of the two connecting rods that are far apart from each other, a second slide rod is slidably connected in the second slider, and a lifting assembly for raising and lowering the massage roller is provided in the first sliding groove of the shoulder support plate.

[0010] By adopting the above technical solution, when the pressure block is pressed and pushed, the massage roller can be driven to roll on the patient's shoulder.

[0011] Furthermore, the lifting assembly includes a first slider fixed at both ends of the second slide rod, the shoulder support plate is symmetrically constructed with mounting grooves in the first sliding groove, the first slide rod is symmetrically fixed in the mounting groove on the shoulder support plate, the first slider is sleeved on the surface of the first slide rod, and a fixing member for fixing the first slider is provided on one side of the shoulder support plate.

[0012] By adopting the above technical solution, the massage roller can be raised and lowered by sliding the first slider on the surface of the first slide rod, and the massage roller can be fixed by the fixing component.

[0013] Furthermore, the fixing member includes a limiting groove constructed on one side of a first slider, a second sliding groove constructed on one side of the shoulder support plate, a limiting rod slidably connected to the shoulder support plate within the second sliding groove, and the limiting rod is adapted to the limiting groove, a handle is fixed to the end of the limiting rod away from the limiting groove, an annular block is fixed to the surface of the limiting rod, and a first spring is fixed to the shoulder support plate within the second sliding groove, one end of the first spring being fixedly connected to the annular block.

[0014] By adopting the above technical solution, when a patient needs a shoulder massage, pulling the handle moves the annular block, which in turn causes the first spring to contract, eventually moving the limiting rod out of the limiting groove. Then, the weight of the massage roller causes the first slider to slide to the bottom of the first sliding rod. After the patient finishes the massage, pulling the lower pressure block moves the massage roller upward, while simultaneously pulling the handle moves the limiting groove into the second sliding groove. When the limiting groove and the second sliding groove are in the same position, releasing the handle causes the first spring to rebound, moving the limiting rod into the limiting groove.

[0015] Furthermore, the pre-fixing mechanism includes two square slots constructed on the side of the first neck fixing frame near the second neck fixing frame, and the two square slots are symmetrically constructed. A limiting block is symmetrically fixed on the side of the second neck fixing frame near the first neck fixing frame. A moving groove is constructed on one side of the limiting block. A second spring is fixed inside the moving groove. A semi-circular block is fixed at one end of the second spring. The first neck fixing frame is located in the square slot and has a semi-circular groove constructed, and the semi-circular groove is adapted to the semi-circular block.

[0016] By adopting the above technical solution, when the first neck fixing bracket and the second neck fixing bracket approach each other, the semicircular block can come into contact with the first neck fixing bracket, thereby driving the second spring to contract, and then the semicircular block moves into the moving groove. When the limiting block is fully inserted into the square groove, the semicircular block is matched with the semicircular groove, the second spring rebounds, and drives the semicircular block to move into the semicircular groove.

[0017] Furthermore, the sliding mechanism includes two first support rods symmetrically fixed to the top of a shoulder support plate, a second support rod fixed to the top of another first support rod, and a third support rod fixed to the top of another shoulder support plate. The second and third support rods are symmetrical to each other. A second fixing block is fitted onto the surface of each of the two first support rods and the third support rod. A first fixing block is fitted onto the surface of the second support rod. One second fixing block is fixedly connected to the first fixing block and the first head fixing frame. Both second fixing blocks are fixedly connected to the second head fixing frame. An abutment block is fixed to the top of each of the first, second, and third support rods. A fixing rod is threaded onto one side of the first fixing block, and the end of the fixing rod abuts against the surface of the second support rod.

[0018] By adopting the above technical solution, the first fixing block slides on the surface of the second support rod, and the second fixing block slides on the surfaces of the first and third support rods, thereby driving the first head fixing frame and the second head fixing frame to rise and fall. Then, by rotating the fixing rod clockwise, the end of the fixing rod abuts against the surface of the second support rod, thereby fixing the first head fixing frame.

[0019] Furthermore, the first neck fixation frame, the second neck fixation frame, the first head fixation frame, and the second head fixation frame are all provided with ventilation holes, and the ventilation holes penetrate through the first neck fixation frame, the second neck fixation frame, the first head fixation frame, and the second head fixation frame.

[0020] By adopting the above technical solution, when the weather is relatively hot, the ventilation holes can improve the comfort of patients wearing the device.

[0021] Furthermore, the inner sides of the first neck fixation frame, the second neck fixation frame, the first head fixation frame, and the second head fixation frame are all detachably connected to a sweat-absorbing layer, and the inner side of the sweat-absorbing layer is detachably connected to an antibacterial layer.

[0022] By adopting the above technical solution, the sweat-absorbing layer is made of flax fiber, which can effectively absorb the patient's sweat, while the antibacterial layer can inhibit the growth of bacteria.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. When a patient experiences shoulder discomfort after wearing the device for an extended period, medical staff can press and push the lower pressure block to move the connecting frame, which in turn causes the massage rollers to roll on the patient's shoulder, massaging the shoulder, improving blood circulation, and thus relaxing the patient's shoulder.

[0025] 2. When the weather is hot, the ventilation holes increase the breathability of the device, improving the comfort of the patient. This allows for more comprehensive contact between the patient, head, and neck and the air. The sweat-absorbing layer is made of linen fiber, which has good moisture absorption and can absorb up to 20 times its own weight in water, effectively absorbing the patient's sweat. The antibacterial layer is made of bamboo charcoal fiber, which absorbs sweat while inhibiting bacterial growth.

[0026] 3. When the first neck fixing bracket and the second neck fixing bracket approach each other, the semicircular block abuts against the first neck fixing bracket, thereby causing the second spring to contract and move the semicircular block into the moving groove. When the limiting block is fully inserted into the square groove, the semicircular block is matched with the semicircular groove, the second spring rebounds, and the semicircular block moves into the semicircular groove, thus pre-fixing the first neck fixing bracket and the second neck fixing bracket and improving the stability between the first neck fixing bracket and the second neck fixing bracket.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] This application discloses a head and neck shock absorption and fixation device.

[0038] Reference Figure 1 , Figure 3 and Figure 5A head and neck shock absorption and fixation device includes a first neck fixation frame 1 and a second neck fixation frame 2. Shoulder support plates 3 are fixed to the sides of both the first and second neck fixation frames 1 and 2 that are far apart from each other. The bottom of each shoulder support plate 3 has an arc-shaped groove 18, and the top of each shoulder support plate 3 has a first sliding groove. Massage rollers 16 are installed within the first sliding grooves of each shoulder support plate 3. A moving mechanism is provided within the sliding grooves of the shoulder support plates 3 to allow the massage rollers 16 to move within the first sliding grooves. The first neck fixation frame 1... The top of the device is symmetrically provided with a first head fixing bracket 4 and a second head fixing bracket 5. Both ends of the first neck fixing bracket 1 and the first head fixing bracket 4 are fixed with Velcro 7. Both ends of the second neck fixing bracket 2 and the second head fixing bracket 5 are fixed with fixing rings 6. A pre-fixing mechanism for pre-fixing the first neck fixing bracket 1 and the second neck fixing bracket 2 is provided on one side of the first neck fixing bracket 1. The Velcro 7 is adapted to the fixing rings 6. The top of the shoulder support plate 3 is provided with a sliding mechanism for allowing the first head fixing bracket 4 and the second head fixing bracket 5 to slide up and down. When using this head and neck shock absorption and fixation device, first align the first neck fixation frame 1 and the second neck fixation frame 2 with the patient's neck, then adjust the height of the first head fixation frame 4 and the second head fixation frame 5 through the sliding mechanism to suit different patients' heads. Then, pre-fix the first neck fixation frame 1 and the second neck fixation frame 2 through the pre-fixation mechanism, and then fix the device by passing the Velcro 7 through the fixing ring 6. At the same time, the arc groove 18 fits against the patient's shoulder. When the patient feels discomfort in their shoulder after wearing the device for a long time, the massage roller 16 moves in the first sliding groove through the moving mechanism to massage the patient's shoulder, which is more conducive to long-term wear.

[0039] Reference Figure 3 , Figure 5 and Figure 6 The moving mechanism includes connecting rods 22 symmetrically rotatably connected to both sides of the massage roller 16. Connecting frames 23 are fixed to the surfaces of the two connecting rods 22, and a pressing block 17 is fixed to the top of the connecting frame 23. Second sliders 26 are fixed to the sides of the two connecting rods 22 that are far apart from each other. A second sliding rod 27 is slidably connected within the second slider 26. A lifting assembly for raising and lowering the massage roller 16 is located within the first sliding groove of the shoulder support plate 3. By pressing and pushing the pressing block 17, the connecting frame 23 is moved, thereby causing the massage roller 16 to roll on the patient's shoulder, providing a massage.

[0040] Reference Figure 5-6The lifting assembly includes first sliders 21 fixed at both ends of the second slide rod 27. A shoulder support plate 3 has symmetrically constructed mounting grooves 19 within a first sliding groove. First slide rods 20 are symmetrically fixed to the shoulder support plate 3 within the mounting grooves 19. The first sliders 21 are sleeved on the surface of the first slide rods 20. A fixing member is provided on one side of the shoulder support plate 3 for fixing the first sliders 21. By sliding the first sliders 21 on the surface of the first slide rods 20, the massage rollers 16 can be raised and lowered, allowing the massage rollers 16 to massage shoulders at different heights, thus broadening the applicability of the device. After the massage, the massage rollers 16 can be fixed by the fixing member, preventing them from contacting the patient's shoulders.

[0041] Reference Figure 3 , Figure 5 and Figure 6 The fixing component includes a limiting groove 31 constructed on one side of a first slider 21, a second sliding groove constructed on one side of a shoulder support plate 3, a limiting rod 24 slidably connected to the shoulder support plate 3 within the second sliding groove, and the limiting rod 24 is adapted to the limiting groove 31. A handle 30 is fixed to one end of the limiting rod 24 away from the limiting groove 31, and an annular block 28 is fixed to the surface of the limiting rod 24. A first spring 29 is fixed to the shoulder support plate 3 within the second sliding groove, and one end of the first spring 29 is fixedly connected to the annular block 28. When a patient needs a shoulder massage, pulling the handle 30 moves the limiting rod 24, which in turn moves the annular block 28, causing the first spring 29 to contract. Finally, the limiting rod 24 moves out of the limiting groove 31. Then, the weight of the massage roller 16 causes the first slider 21 to slide to the bottom of the first slide bar 20. After the patient finishes the massage, pulling the pressure block 17 moves the first slider 21 upward along the surface of the first slide bar 20. At the same time, pulling the handle 30 moves the limiting groove 31 into the second slide groove. When the limiting groove 31 and the second slide groove are on the same plane, releasing the handle 30 causes the first spring 29 to rebound, moving the limiting rod 24 into the limiting groove 31 to fix the first slider 21.

[0042] Reference Figure 4 and Figure 7The pre-fixing mechanism includes two square grooves 33 constructed on the side of the first neck fixing frame 1 near the second neck fixing frame 2, and the two square grooves 33 are symmetrically constructed. Limiting blocks 32 are symmetrically fixed on the side of the second neck fixing frame 2 near the first neck fixing frame 1. A moving groove 36 is constructed on one side of the limiting block 32. A second spring 37 is fixed on the inner side of the moving groove 36. A semi-circular block 35 is fixed on one end of the second spring 37. A semi-circular groove 34 is constructed in the square groove 33 of the first neck fixing frame 1, and the semi-circular groove 34 is adapted to the semi-circular block 35. When the first neck fixation bracket 1 and the second neck fixation bracket 2 approach each other, the semicircular block 35 abuts against the first neck fixation bracket 1, thereby causing the second spring 37 to contract, and thus causing the semicircular block 35 to move into the moving groove 36. When the limiting block 32 is fully inserted into the square groove 33, the semicircular block 35 is matched with the semicircular groove 34, the second spring 37 rebounds, and causes the semicircular block 35 to move into the semicircular groove 34, so that the first neck fixation bracket 1 and the second neck fixation bracket 2 are simply fixed, which improves the stability between the first neck fixation bracket 1 and the second neck fixation bracket 2.

[0043] Reference Figure 1-4 The sliding mechanism includes two first support rods 8 symmetrically fixed to the top of a shoulder support plate 3, a second support rod 38 fixed to the top of another first support rod 8, and a third support rod 39 fixed to the top of another shoulder support plate 3. The second support rods 38 and 39 are symmetrical to each other. A second fixing block 14 is fitted on the surface of each of the two first support rods 8 and the third support rod 39. A first fixing block 13 is fitted on the surface of the second support rod 38. One second fixing block 14 and the first fixing block 13 are fixedly connected to the first head fixing frame 4. The two second fixing blocks 14 are fixedly connected to the second head fixing frame 5. A contact block 12 is fixed to the top of each of the first support rods 8, the second support rod 38 and the third support rod 39. A fixing rod 15 is threadedly connected to one side of the first fixing block 13, and the end of the fixing rod 15 abuts against the surface of the second support rod 38. The first fixing block 13 slides on the surface of the second support rod 38, and the second fixing block 14 slides on the surfaces of the first support rod 8 and the third support rod 39, thereby driving the first head fixation frame 4 and the second head fixation frame 5 to rise and fall, so that the device can be adapted to the heads of different patients. Then, by rotating the fixing rod 15 clockwise, the end of the fixing rod 15 abuts against the surface of the second support rod 38, thereby fixing the first head fixation frame 4 and the second head fixation frame 5.

[0044] Reference Figure 1 , Figure 2 and Figure 4The first neck fixation frame 1, the second neck fixation frame 2, the first head fixation frame 4, and the second head fixation frame 5 are all equipped with ventilation holes 11, which extend through these frames. The ventilation holes 11 increase the breathability of the device during wear, improving patient comfort in hot weather and ensuring more comprehensive contact between the patient, head, and neck with the air.

[0045] Reference Figure 1 , Figure 3 and Figure 4 The inner sides of the first neck fixation frame 1, the second neck fixation frame 2, the first head fixation frame 4, and the second head fixation frame 5 are all detachable and connectable to a sweat-absorbing layer 9. An antibacterial layer 10 is detachably connected to the inner side of the sweat-absorbing layer 9. The sweat-absorbing layer 9 is made of flax fiber, which exists in the bast tissue of flax stems. Flax fiber is characterized by its excellent moisture absorption, capable of absorbing up to 20 times its own weight in water. It also offers benefits such as rapid moisture wicking, hypoallergenic properties, antistatic properties, and antibacterial properties. The antibacterial layer 10 is made of bamboo charcoal fiber. While the sweat-absorbing layer 9 absorbs sweat, the antibacterial layer 10 inhibits bacterial growth, improving the cleanliness of the device and increasing patient comfort when using it.

[0046] The implementation principle of the head and neck shock absorption and fixation device in this embodiment is as follows: When using the head and neck shock absorption and fixation device, firstly, the first neck fixation frame 1 and the second neck fixation frame 2 are positioned against the patient's neck. Then, the first fixing block 13 slides on the surface of the second support rod 38, and the second fixing block 14 slides on the surfaces of the first support rod 8 and the third support rod 39, driving the first head fixation frame 4 and the second head fixation frame 5 to rise and fall, making the device suitable for different patients' heads. Subsequently, by rotating the fixing rod 15 clockwise, the end of the fixing rod 15 abuts against the surface of the second support rod 38, fixing the first head fixation frame 4 and the second head fixation frame 5, making it suitable for different patients' heads. Then, when the first neck fixation frame 1 and the second head fixation frame 5 are aligned, the device is adjusted accordingly. When the neck fixation frames 2 approach each other, the semicircular block 35 abuts against the first neck fixation frame 1, thereby causing the second spring 37 to contract, which in turn moves the semicircular block 35 into the moving groove 36. When the limiting block 32 is fully inserted into the square groove 33, the semicircular block 35 matches the semicircular groove 34, the second spring 37 rebounds, and moves the semicircular block 35 into the semicircular groove 34, thus providing a simple fixation between the first neck fixation frame 1 and the second neck fixation frame 2, improving the stability between the first neck fixation frame 1 and the second neck fixation frame 2. Then, the device is fixed by passing the Velcro 7 through the fixing ring 6. At the same time, the arc-shaped groove 18 fits against the patient's shoulder. When the patient feels discomfort in the shoulder after wearing the device for a long time, the device can be adjusted by... Pulling the handle 30 moves the limiting rod 24, which in turn moves the annular block 28. This causes the first spring 29 to retract, and finally, the limiting rod 24 moves out of the limiting groove 31. The weight of the massage roller 16 then causes the first slider 21 to slide to the bottom of the first slide bar 20. Simultaneously, the first spring 29 rebounds, returning the limiting rod 24 to its original position. Pressing and pushing the lower pressure block 17 moves the connecting frame 23, causing the massage roller 16 to roll on the patient's shoulder, providing a massage and increasing patient comfort. After the massage, pulling the lower pressure block 17 moves the first slider 21 upwards along the surface of the first slide bar 20. Pulling the handle 30 moves the limiting groove 31 into the second sliding groove. When the limiting groove 31 and the second sliding groove are on the same plane, releasing the handle 30 causes the first spring 29 to rebound, moving the limiting rod 24 into the limiting groove 31 to fix the first slider 21. When the weather is hot, the ventilation holes 11 can increase the breathability of the device when worn, improving the comfort of the patient. This makes the contact surface between the patient, head and neck and the air more comprehensive. At the same time, the sweat-absorbing layer 9 can absorb the patient's sweat. While the sweat-absorbing layer 9 absorbs the sweat, the antibacterial layer 10 can inhibit the growth of bacteria, improving the cleanliness of the device and increasing the patient's comfort when using it.
