A lumbar vertebra protection device for a hematological patient with myeloma

Abstract

This invention provides a lumbar support device for hematological myeloma patients, belonging to the field of medical devices. It includes a lumbar support board with curved plates fixedly connected to both sides. One side of one curved plate is fixedly connected to a first textured Velcro strap, and the other side of the curved plate is fixedly connected to a restraint strap. One side of the restraint strap is fixedly connected to a first hook-and-loop Velcro strap. A foam column is fixedly connected to the front of the lumbar support board. The lumbar support board has compression components on both sides inside to promote lumbar blood circulation. When the lumbar region comes into contact with the rotating sleeve, it tightly compresses the rotating sleeve and compresses two second springs, allowing multiple second springs to better conform to the patient's lumbar region. This ensures that both sides of the lumbar spine are supported, avoiding excessive pressure on the healthy side and insufficient support on the affected side, preventing muscle imbalance on both sides of the lumbar spine, and preventing lumbar rotational deformity.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a lumbar spine protection device for hematological myeloma patients. Background Technology

[0002] Hematologic disorders encompass a wide range of conditions, including iron deficiency anemia, aplastic anemia, paroxysmal nocturnal hemoglobinuria, idiopathic thrombocytopenic purpura, acute leukemia, chronic leukemia, malignant lymphoma, polycythemia vera, essential thrombocythemia, myelofibrosis, multiple myeloma, hemophilia, and more. Diagnosis of hematologic disorders involves routine blood tests, liver and kidney function tests, and bone marrow cytology. Some patients also require lumbar puncture and intrathecal injections to prevent central nervous system leukemia. Treatment for hematologic disorders relies on medication and often includes wearing masks, admission to laminar flow wards or cleanrooms to reduce the risk of infection. Furthermore, some myeloma patients, due to osteoporosis and severe bone destruction, require lumbar support braces to prevent fractures.

[0003] Currently, traditional lumbar support belts provide support to the lower back in a single, integrated structure (which cannot be adjusted to the left and right sides of the lower back). However, there is a natural difference in muscle strength between the left and right sides of the human lumbar spine, and injuries such as lumbar disc herniation and scoliosis are mostly unilateral. Existing support belts can lead to excessive compression on the healthy side and insufficient support on the affected side. Long-term use can exacerbate the imbalance of muscles on both sides of the lumbar spine and even induce lumbar rotational deformity. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a lumbar spine protection device for hematological myeloma patients.

[0005] To solve the above problems, the present invention adopts the following technical solution: a lumbar spine protection device for hematology myeloma patients, including a lumbar support board, with arc-shaped plates fixedly connected to both sides of the lumbar support board, a first textured Velcro fastener fixedly connected to one side of one arc-shaped plate, a restraint strap fixedly connected to one side of the other arc-shaped plate, a first hook-and-loop Velcro fastener fixedly connected to one side of the restraint strap, a foam column fixedly connected to the front side of the lumbar support board, and lumbar compression components to promote lumbar blood circulation are provided on both sides inside the lumbar support board.

[0006] The lumbar support assembly includes a rectangular groove inside the lumbar support plate and a guide groove fixed to the outside of the arc-shaped plate. The top and bottom of the rectangular groove are provided with sliding grooves. A movable plate is slidably connected inside the sliding grooves. A metal pull rope is fixedly connected to one side of the back of the movable plate. A first spring is fixedly connected to one side of the movable plate. A second spring is fixedly connected to the top and bottom of the front side of the movable plate. A mounting bracket is fixedly connected to the front side of the second spring. A fixed shaft is fixedly connected inside the mounting bracket. A rotating sleeve is rotatably connected to the outer surface of the fixed shaft. A pull ring is fixedly connected to one side of the metal pull rope.

[0007] Optionally, two metal pull ropes are fixedly connected to one side of the back of the movable plate. The metal pull ropes pass through the interior of the guide groove. The two metal pull ropes form a group. A pull ring is fixedly connected to one side of the two metal pull ropes. A second hook-and-loop fastener and a second rough-surface hook-and-loop fastener are fixedly connected to the sides of the two pull rings that are close to each other. The second rough-surface hook-and-loop fastener and the second hook-and-loop fastener are attached to each other.

[0008] Optionally, eight second springs are provided in pairs, and a mounting bracket is fixedly connected to the front side of two second springs. Four mounting brackets and four rotating sleeves are provided, and a blood circulation component is provided inside the rotating sleeve.

[0009] Optionally, the other side of the first spring is fixedly connected to the inner side of the rectangular groove, and a limiting rod is fixedly connected to the middle of one side of the back of the mounting bracket. The limiting rod extends into the interior of the movable plate and slides against each other.

[0010] Optionally, the blood circulation component includes an installation groove inside the rotating sleeve and two wavy grooves on the outer surface of the fixed shaft. Each wavy groove has two sliders slidably connected inside. A movable block is fixedly connected to one side of each slider, and multiple balls are rotatably connected to one side of each movable block.

[0011] Optionally, the movable block is located inside the mounting groove and slides inside the mounting groove. Two opposite movable blocks form a group, and the two corresponding sliders are located inside the same wavy groove.

[0012] Optionally, a lumbar support assembly is provided on one side of the back of the lumbar support plate. The lumbar support assembly includes a fixed frame fixed in the middle of one side of the back of the lumbar support plate and two through slots opened on the front side of the fixed frame. Two metal side plates are fixedly connected to the inner top and inner bottom of the fixed frame. The two metal side plates have slots inside. Sliding members are slidably connected inside the two slots. Fixing blocks are fixedly connected to both sides of the sliding members. Through holes are opened inside the fixing blocks. First locking plates are symmetrically fixedly connected to the outer surface of the sliding members. A metal support plate is rotatably connected to the middle of the outer surface of the sliding members. Second locking plates are fixedly connected to both sides of the top of the metal support plate. Second magnets are fixedly connected to both sides of the metal support plate near the bottom. A fixing component is provided in the middle of one side of the metal side plate.

[0013] Optionally, the fixing component includes a support rod fixed to one side of the metal side plate, a third spring sleeved on the outer surface of the support rod, a hook slidably connected to the outer surface of the support rod, a push rod fixedly connected to the front side of the hook, one side of the push rod penetrating the interior of the through groove, and a stabilizing component provided at the bottom of one side of the metal support plate.

[0014] Optionally, the stabilizing component includes a storage slot on the front side of a metal support plate, with anti-slip plates rotatably connected to both sides inside the storage slot, a first magnet fixedly connected to the top of the anti-slip plates, and an anti-slip pad fixedly connected to the bottom of the anti-slip plates.

[0015] Optionally, the anti-slip plate can be stored inside the storage slot, and the first magnet and the metal support plate are attracted to each other.

[0016] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a waist-pressing component, when the waist comes into contact with the rotating sleeve, the rotating sleeve is tightly squeezed and the two second springs are compressed, so that the multiple second springs can better fit the patient's waist, ensuring that both sides of the patient's lumbar spine can be supported, avoiding excessive compression on the healthy side and insufficient support on the affected side, preventing muscle imbalance on both sides of the lumbar spine, and preventing lumbar rotational deformity.

[0018] By setting up a blood-activating component, when the rotating sleeve rotates, it drives the moving block to rotate around the fixed axis through the mounting groove. Through the cooperation of the slider and the wave-shaped groove, the slider drives the moving block to move up and down inside the mounting groove. The moving block drives the ball to squeeze the patient's skin. The ball has a small contact area with the skin, which has a better skin stimulation effect, accelerates blood flow in the waist, and improves blood oxygen saturation to a normal level.

[0019] By setting up a lumbar support assembly, the metal support plate and anti-slip plate are unfolded in sequence, and the anti-slip mat is supported on the bed surface. The anti-slip mat and the bed surface support each other to effectively improve the stability of the metal support plate. The metal support plate supports and lifts the waist, ensuring that the patient's waist is in a comfortable state. Attached Figure Description

[0045] like Figures 1 to 9 As shown in the figure, an embodiment of the present invention provides a lumbar spine protection device for hematology myeloma patients, including a lumbar support plate 1. Arc-shaped plates 3 are fixedly connected to both sides of the lumbar support plate 1. A first textured Velcro 5 is fixedly connected to one side of one arc-shaped plate 3, and a restraint strap 4 is fixedly connected to one side of the other arc-shaped plate 3. A first hook-and-loop Velcro 8 is fixedly connected to one side of the restraint strap 4. The first textured Velcro 5 and the first hook-and-loop Velcro 8 are fitted together. A foam column 2 is fixedly connected to the front side of the lumbar support plate 1, and lumbar compression components 6 that promote lumbar blood circulation are provided on both sides inside the lumbar support plate 1.

[0046] like Figures 2-3As shown, the lumbar support assembly 6 includes a rectangular groove 61 inside the lumbar support plate 1 and a guide groove 64 fixed to the outside of the arc-shaped plate 3. The top and bottom of the rectangular groove 61 are provided with sliding grooves 62. A movable plate 63 is slidably connected inside the sliding groove 62. A metal pull rope 65 is fixedly connected to one side of the back of the movable plate 63. One end of a first spring 66 is fixedly connected to one side of the movable plate 63. The other end of the first spring 66 is connected to the inside of the rectangular groove 61. One end of a second spring 67 is fixedly connected to the top and bottom of the front side of the movable plate 63. The other end of the second spring 67 is fixedly connected to a mounting bracket 611. A fixed shaft 69 is fixedly connected inside the mounting bracket 611. A rotating sleeve 610 is rotatably connected to the outer surface of the fixed shaft 69. A pull ring 614 is fixedly connected to one side of the metal pull rope 65.

[0047] For example Figure 2 As shown, two metal pull ropes 65 are fixedly connected to one side of the back of the movable plate 63. The metal pull ropes 65 pass through the interior of the guide groove 64. The two metal pull ropes 65 form a group. A pull ring 614 is fixedly connected to one side of the two metal pull ropes 65. A second hook-and-loop fastener 613 and a second rough-surface hook-and-loop fastener 612 are fixedly connected to the sides of the two pull rings 614 that are close to each other. The second rough-surface hook-and-loop fastener 612 and the second hook-and-loop fastener 613 are attached to each other.

[0048] For example Figure 3 As shown, there are eight second springs 67 arranged in pairs. A mounting bracket 611 is fixedly connected to the front side of two second springs 67. There are four mounting brackets 611 and four rotating sleeves 610. A blood circulation component 68 is arranged inside the rotating sleeve 610. A limit rod is fixedly connected to the middle of one side of the back of the mounting bracket 611. The limit rod extends into the interior of the moving plate 63 and slides against each other.

[0049] When wearing the lumbar support device, the patient fits the lumbar support plate 1 against the waist, pulls the restraint strap 4 and the first hook-and-loop fastener 5 to fit tightly against the patient's side, covers the patient's abdomen with the first hook-and-loop fastener 5, and then attaches the first hook-and-loop fastener 8 to the surface of the first hook-and-loop fastener 5. The lumbar support plate 1 and the arc plate 3 are then fixed to the waist. The foam column 2 compresses the patient's lumbar spine to ensure that the lumbar spine is evenly stressed. When the waist comes into contact with the rotating sleeve 610, it compresses the rotating sleeve 610 tightly and compresses the two second springs 67, so that the multiple second springs 67 can fit better against the patient's waist, ensuring that both sides of the patient's lumbar spine can be supported, avoiding excessive compression on the healthy side and insufficient support on the affected side, preventing muscle imbalance on both sides of the lumbar spine, and inducing lumbar rotational deformity.

[0050] After wearing it for a period of time, the waist is compressed for a long time, which leads to poor blood flow in the waist area, decreased blood oxygen saturation in the waist skin, and accumulation of local metabolic waste, causing skin darkening, muscle stiffness, and even mild edema in the lower limbs. At this time, pulling the two pull rings 614 will drive the moving plate 63 to slide inside the slide groove 62 through the metal pull rope 65. The moving plate 63 will drive multiple mounting brackets 611 to move through the limiting rod. The mounting brackets 611 will drive the rotating sleeve 610 to roll on the patient's waist, so that the rotating sleeve 610 will be removed from the compression point. The movement of the moving plate 63 will compress the first spring 66, reduce the pain at the compression point, and solve the problem of poor blood flow at the compression point. Then, the first spring 66 will drive the moving plate 63 to reset. This cycle massages the waist. The pull rings 614 and the second hook-and-loop fasteners 613 are attached and fixed to each other to prevent the pull rings 614 from hanging on the device.

[0051] like Figures 4-5 As shown, the blood circulation component 68 includes a mounting groove 681 inside the rotating sleeve 610 and two wavy grooves 685 on the outer surface of the fixed shaft 69. Two sliders 684 are slidably connected inside each wavy groove 685. A movable block 682 is fixedly connected to one side of each slider 684, and multiple ball bearings 683 are rotatably connected to one side of each movable block 682. The movable block 682 slides inside the mounting groove 681. Two opposing movable blocks 682 form a group, and the corresponding two sliders 684 are located inside the same wavy groove 685.

[0052] When the rotating sleeve 610 rolls over the patient's waist, it can massage the compression area, but it does not provide sufficient stimulation to the waist and is not very effective in improving poor blood flow. Therefore, when the rotating sleeve 610 rotates, it drives the moving block 682 to rotate around the fixed axis 69 through the mounting groove 681. The moving block 682 drives the slider 684 to slide inside the wavy groove 685. Because the wavy groove 685 is wavy, the slider 684 drives the moving block 682 to move up and down inside the mounting groove 681. The moving block 682 drives the ball bearing 683 to compress the patient's skin. The ball bearing 683 has a small contact area with the skin, which provides better stimulation to the skin, accelerates blood flow in the waist, and improves blood oxygen saturation to a normal level.

[0053] like Figures 6-9As shown, a lumbar support assembly 7 is provided on one side of the back of the lumbar support plate 1. The lumbar support assembly 7 includes a fixed frame 71 fixed in the middle of one side of the back of the lumbar support plate 1 and two through slots 716 opened on the front side of the fixed frame 71. Two metal side plates 73 are fixedly connected to the inner top and inner bottom of the fixed frame 71. The two metal side plates 73 have slots 77 inside. Sliding members 75 are slidably connected inside the two slots 77. Fixed blocks 72 are fixedly connected to both sides of the sliding members 75. Through holes 712 are opened inside the fixed blocks 72. First locking plates 714 are symmetrically fixedly connected to the outer surface of the sliding members 75. A metal support plate 74 is rotatably connected to the middle of the outer surface of the sliding members 75. Second locking plates 715 are fixedly connected to both sides of the top of the metal support plate 74. Second magnets 713 are fixedly connected to both sides of the metal support plate 74 near the bottom.

[0054] like Figure 8 As shown, a fixing component is provided in the middle of one side of the metal side plate 73. The fixing component includes a support rod 710 fixed to one side of the metal side plate 73, a third spring 711 sleeved on the outer surface of the support rod 710, a hook 78 slidably connected to the outer surface of the support rod 710, a push rod 79 fixedly connected to the front side of the hook 78, one side of the push rod 79 penetrating the interior of the through groove 716, and a stabilizing component 76 is provided at the bottom of one side of the metal support plate 74.

[0055] like Figure 9 As shown, the stabilizing component 76 includes a storage slot 761 located on the front side of the metal support plate 74. Anti-slip plates 762 are rotatably connected to both sides inside the storage slot 761. A first magnet 763 is fixedly connected to the top of the anti-slip plate 762, and an anti-slip pad 764 is fixedly connected to the bottom of the anti-slip plate 762. The anti-slip plate 762 can be stored inside the storage slot 761, and the first magnet 763 and the metal support plate 74 are attracted to each other.

[0056] When the patient is sitting or leaning against the headboard, but after wearing the device, the patient's lower back is in a straight position, making it impossible for the patient to lean against the headboard. This prolonged suspension of the lower back can cause muscle soreness. Therefore, when the patient is sitting, the metal support plate 74 is rotated out from inside the fixing frame 71. Pulling the metal support plate 74, via the slider 75, causes the fixing block 72 to slide downwards on one side of the metal side plate 73. This allows the side of the through hole 712 to contact and slide against the inclined side of the hook 78, pushing the hook 78 to move to one side outside the support rod 710. When the hook 78 is fully inserted into the through hole 712, the third spring 711 pushes the hook 78 to lock onto the fixing block 72, securing the block 72. Rotating the metal support plate 74 causes the second locking plate 715 to rotate synchronously until the first locking plate 714 blocks the second locking plate 715, preventing the metal support plate 74 from rotating further. Next, remove the anti-slip plate 762 from the storage slot 761 so that the anti-slip pad 764 is supported on the bed surface. The anti-slip pad 764 and the bed surface support each other to effectively improve the stability of the metal support plate 74. The metal support plate 74 supports and lifts the waist to ensure that the patient's waist is in a comfortable state.

[0057] When storing, press the two push rods 79 to move the hook 78 to the other side of the through hole 712, then push the metal support plate 74 upward so that the fixing block 72 leaves the hook 78, and store the metal support plate 74 between the two metal side plates 73. The second magnet 713 and the metal side plate 73 attract each other to fix the metal support plate 74. Store the anti-slip plate 762 inside the storage slot 761. The first magnet 763 and the metal support plate 74 attract each other to fix the anti-slip plate 762.

[0058] The workflow of the technical solution provided by this invention is as follows:

[0059] When wearing the lumbar support device, the patient fits the lumbar support plate 1 against the waist, pulls the restraint strap 4 and the first hook-and-loop fastener 5 to fit tightly against the patient's side waist, covers the patient's abdomen with the first hook-and-loop fastener 5, and then attaches the first hook-and-loop fastener 8 to the surface of the first hook-and-loop fastener 5. The lumbar support plate 1 and the arc plate 3 are then fixed to the waist. The foam column 2 compresses the patient's lumbar spine to ensure that the lumbar spine is evenly stressed. When the waist comes into contact with the rotating sleeve 610, it compresses the rotating sleeve 610 tightly and compresses the two second springs 67, so that the multiple second springs 67 can fit better against the patient's waist, ensuring that both sides of the patient's lumbar spine can be supported, avoiding excessive compression on the healthy side and insufficient support on the affected side, preventing muscle imbalance on both sides of the lumbar spine, and inducing lumbar rotational deformity.

[0060] Pulling the two pull rings 614 causes the moving plate 63 to slide inside the slide groove 62 via the metal pull rope 65. The moving plate 63 moves multiple mounting brackets 611 via the limit rod. The mounting brackets 611 cause the rotating sleeve 610 to roll on the patient's waist, causing the rotating sleeve 610 to move away from the compression point. The moving plate 63 moves and compresses the first spring 66, reducing the pain at the compression point and solving the problem of poor blood flow at the compression point. Then, the first spring 66 drives the moving plate 63 to reset. This cycle massages the waist. The pull rings 614 and the second hook-and-loop fastener 613 are attached and fixed to each other to prevent the pull rings 614 from hanging on the device.

[0061] When the rotating sleeve 610 rotates, it drives the moving block 682 to rotate around the fixed shaft 69 through the mounting groove 681. The moving block 682 drives the slider 684 to slide inside the wavy groove 685. Because the wavy groove 685 is wavy, the slider 684 drives the moving block 682 to move up and down inside the mounting groove 681. The moving block 682 drives the ball 683 to squeeze the patient's skin. The ball 683 has a small contact area with the skin, which has a better skin stimulation effect, accelerates blood flow in the waist, and improves blood oxygen saturation to a normal level.

[0062] When the patient is in a sitting position, the metal support plate 74 is rotated out from inside the fixed frame 71, and the metal support plate 74 is pulled to drive the fixed block 72 to slide downward on one side of the metal side plate 73 through the slider 75, so that the side of the through hole 712 contacts and slides with the inclined side of the hook 78, pushing the hook 78 to move to one side outside the support rod 710. When the hook 78 is fully inserted into the through hole 712, the third spring 711 pushes the hook 78 to lock onto the fixed block 72 and fix the fixed block 72. Rotating the metal support plate 74 drives the second locking plate 715 to rotate synchronously until the first locking plate 714 blocks the second locking plate 715, and the metal support plate 74 can no longer rotate. Then the anti-slip plate 762 is taken out from inside the storage slot 761, so that the anti-slip pad 764 is supported on the bed surface. The anti-slip pad 764 and the bed surface support each other to effectively improve the stability of the metal support plate 74. The metal support plate 74 supports and lifts the waist, ensuring that the patient's waist is in a comfortable state.
