Description

Technical Field

[0001] This invention relates to the field of lumbar spine care equipment technology, specifically a comfortable lumbar spine care device for hematology rehabilitation. Background Technology

[0002] Hematology, also known as blood science, is a medical discipline that specializes in the study of diseases of the blood and related organs. It encompasses a comprehensive range, from the formation, composition, and function of blood to various pathophysiological processes related to the blood system. Research areas in hematology include bone marrow diseases such as osteomyelitis and myelofibrosis, as well as diseases related to the immune system, such as autoimmune diseases. A deep understanding of lymphatic system diseases, including lymphadenitis and lymphangitis, is also a crucial task of hematology. Hematologists' work extends beyond treating diseases; it also includes prevention and education. They collaborate with patients to develop health management plans, providing advice on diet, lifestyle, and medication to help patients better manage blood-related conditions. For example, hematology patients may require regular lower back massages using nursing devices. Lumbar spine care devices are specifically designed to help relieve lower back discomfort and promote lumbar spine health and rehabilitation. These devices can be used to prevent or treat lumbar spine-related problems such as lumbar muscle strain, herniated discs, and lumbar disc degeneration.

[0003] CN111388160B discloses a medical lumbar care device, including a lumbar care support frame and a lumbar protection device. The lumbar protection device includes two sets of upper lumbar guards and two sets of lower lumbar guards, with the two sets of upper lumbar guards connected by connecting straps. A connecting strap buckle is installed on the left side of the upper lumbar guards via nylon webbing, and a connecting strap buckle is also installed on the left side of the fixed plate via nylon webbing. The lumbar care support frame includes a sliding plate, an adjusting plate, and a vertical plate. Two sets of adjusting plates are hinged to the upper end of the vertical plate via a rotating shaft. A detachable lumbar protection device is installed on the upper end of the sliding plate. This medical lumbar care device is small, easy to wear and carry, and allows for easier device adjustment. It provides better lumbar spine stability and is more conducive to subsequent rehabilitation. Furthermore, the detachable installation of the lumbar protection device on the lumbar care support frame increases the device's versatility, and the adjustable plate spacing accommodates users of different heights.

[0004] CN217510791U discloses a lumbar spine care device, relating to the technical field of lumbar spine care devices. The device includes: a set of symmetrically arranged lumbar support plates, each a curved plate; a support plate base, also a curved plate; and a care device base. Multiple elastic care strips are spaced apart on the top surface of the lumbar support plates, and multiple disc-shaped therapeutic elements are spaced apart on these strips. The support plate base is hollow and contains multiple elastic support elements. The lumbar support plates are connected to the top surface of the support plate base via a set of symmetrical first support rods. The bottom of the support plate base is connected to the top surface of the care device base via detachable second support rods. This application utilizes a simple support structure to support the user's lower back, thereby combining with therapeutic elements to care for the lumbar spine and help the user achieve better lumbar spine care results.

[0005] Most conventional lumbar spine care devices have similar designs, featuring a concave front to better support the patient's lower back and ensure the device fits snugly against the lumbar region, maintaining a massage effect during use. However, different patients have different body types, and conventional lumbar spine massage devices can only move up and down, not horizontally. This means that patients with wider waists cannot receive sufficient massage on both sides of their lower back. Furthermore, when the massage balls move to the sides, the distance between the massage balls and the sides of the lower back increases, affecting the massage effect. In addition, the flat design of the back of ordinary lumbar spine care devices can easily cause discomfort to the user if the chair back is not level or stable. Therefore, a comfortable lumbar spine care device for hematology rehabilitation is needed to address these shortcomings. Summary of the Invention

[0006] Technical problems to be solved

The second gear meshes with the second rack.

[0014] Optionally, the rotating mechanism further includes a moving block, a synchronizing rod, and a second conical wheel. The moving block, the synchronizing rod, and the second conical wheel are symmetrically arranged. The synchronizing rod is movably connected to the inside of the moving groove through bearings.

[0019] Beneficial effects:

[0020] Compared with existing technologies, this comfortable lumbar spine care device for hematology rehabilitation has the following beneficial effects:

[0021] In the above solution, the included angle between connecting rod one and connecting rod two gradually decreases through the set moving mechanism, thereby achieving a protruding effect. At this time, the insertion rod moves away from the insertion hole, and the return spring extends in the insertion hole. Thus, the distance between the lumbar pillow and the chair is controlled by the size of the included angle between connecting rod one and connecting rod two, thereby providing more stable support for the lumbar pillow, improving the stability of the lumbar pillow, and enabling it to operate stably during use.

[0022] The rotating mechanism drives the worm gear to rotate, causing the control lever to rotate synchronously. Since the control lever is threadedly connected to the rack, the two racks move away from each other and drive the gear to rotate, causing the cone wheel, drive lever, and extension rod to rotate synchronously. This allows the massage piece to move horizontally, thereby increasing the horizontal coverage area of ​​the massage piece and making the effect more significant for users with wide waists.

[0023] With the support mechanism in place, the second rack moves faster than the massage piece. During this movement, the second rack rotates, causing the massage piece to rotate synchronously. As the two massage pieces move away from each other, the angle between them gradually decreases, allowing the width between them to cover the horizontal area of ​​the user's waist. This also makes the massage pieces fit the waist more closely, ensuring that they can provide sufficient pressure to the user's waist.

[0043] like Figures 1 to 10As shown, the present invention provides a technical solution: a comfortable lumbar spine care device for hematology rehabilitation, including a lumbar pillow 1 and a massage component 2. A pair of straps 3 are fixedly connected to both sides of the lumbar pillow 1. A set of symmetrical elastic pockets 4 are fixedly connected to the front side of the lumbar pillow 1. A heater 5 is fixedly connected to the front side of the lumbar pillow 1, located on the opposite side of the elastic pockets 4. A base plate 6 is fixedly connected inside the lumbar pillow 1. A pair of movable frames 7 are movably connected inside the base plate 6. An adjusting rod 8 is movably connected inside the base plate 6 via a bearing. The adjusting rod 8 passes through the movable frames 7 and is threadedly connected to the movable frames 7. The base plate 6... A servo motor 9 is fixedly connected to the part, and the output end of the servo motor 9 is fixedly connected to one end of the control rod 8. A moving mechanism 10 is fixedly connected inside the moving frame 7. A set of symmetrical rotating mechanisms 11 is fixedly connected inside the moving frame 7. There are two sets of massage pieces 2, and each set of massage pieces 2 is symmetrically arranged. One end of the rotating mechanism 11 is movably connected to the moving mechanism 10, and the other end of the rotating mechanism 11 is fixedly connected to the massage piece 2. A set of symmetrical support mechanisms 12 is fixedly connected to the back side of the lumbar pillow 1. A support block 13 is fixedly connected to the rear side of the lumbar pillow 1, and the support block 13 is located on the opposite side of the support mechanism 12.

[0044] The lumbar pillow 1 can be fixed to the chair by the strap 3, and the elastic pocket 4 can hold items such as mugwort sachets in front of the lumbar pillow 1. The heater 5 heats the user's lumbar spine to enhance the massage effect. The support mechanism 12 ensures that the lumbar pillow 1 is stably placed on the chair, improving its stability and allowing it to operate stably during use. The servo motor 9 controls the rotation of the control lever 8, which moves the moving frame 7 longitudinally within the base plate 6, thereby adjusting the longitudinal position of the massage component 2 to adapt to different positions of the user's waist and improve the coverage area of ​​the lumbar massage. The moving mechanism 10 controls the horizontal movement of the massage component 2, thereby improving the horizontal coverage area of ​​the massage component 2. This makes the effect more significant for users with wide waists and helps to fully massage the sides of the user's waist, further relieving lumbar fatigue. At the same time, the rotating mechanism 11 makes the angle between the massage components 2 gradually decrease as they move away from each other, allowing the massage component 2 to fit more closely to the user's waist and ensuring that the massage component 2 can fully press on the user's waist.

[0045] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, the moving mechanism 10 includes a drive rod 1001, an extension rod 1002, a conical wheel 1003, a gear 1004, and a rack 1005. The extension rods 1002 are symmetrically arranged and fixedly connected to opposite sides of the drive rod 1001. The conical wheels 1003 are symmetrically arranged, and the extension rods 1002 pass through each of the conical wheels 1003, and are fixedly connected to each other. The drive rod 1001 passes through the gear 1004, and is fixedly connected to each other. The rack 1005 meshes with the gear 1004. The moving mechanism 10 also includes a control rod 1006, a worm gear 1007, and a worm 1008. The control lever 1006 passes through the worm gear 1007 and is fixedly connected to the worm gear 1007. The worm 1008 is movably connected to the inside of the moving frame 7 through a bearing. A set of symmetrical threads is provided on the outer side of the control lever 1006. The control lever 1006 passes through the rack 1005 and is threadedly connected to the rack 1005. A servo motor 14 is fixedly connected inside the moving frame 7, and the output end of the servo motor 14 is fixedly connected to one end of the worm 1008. Two sets of symmetrical moving slots 15 are provided inside the moving frame 7. One end of the extension rod 1002 is movably connected to the inside of the moving slot 15 through a bearing, and the conical wheel 1003 is located inside the moving slot 15.

[0046] The adjustment rod 17 is rotated by the knob 18. Since the adjustment rod 17 is threadedly connected to the moving rod 1204, the moving rod 1204 is moved toward the support block 13. The opposite sides of the connecting rod 1201 and the connecting rod 2 1202 rotate around the movable rod 1203, so that the included angle between the connecting rod 1201 and the connecting rod 2 1202 gradually decreases, thereby achieving a protruding effect. At this time, the insertion rod 1206 moves away from the insertion hole 16, and the return spring 1207 extends in the insertion hole 16. Thus, the distance between the lumbar pillow 1 and the chair is controlled by the size of the included angle between the connecting rod 1201 and the connecting rod 2 1202, thereby providing more stable support for the lumbar pillow 1, improving the stability of the lumbar pillow 1, and enabling it to operate stably during use.

[0047] like Figure 1 , Figure 3 , Figure 6 and Figure 8As shown, the rotating mechanism 11 includes a connecting block 1101, a second gear 1102, a second rack 1103, and a connecting rod 1104. The connecting blocks 1101 are symmetrically arranged and are all fixedly connected to the bottom end of the massage component 2. The second gear 1102 is located on the opposite side of the massage component 2. The connecting rod 1104 passes through the connecting block 1101 and is fixedly connected to the connecting block 1101. The connecting rod 1104 also passes through the second gear 1102 and is fixedly connected to the second gear 1102. The second gear 1102 meshes with the second rack 1103. The rotating mechanism 11 also includes a moving block 1105, a synchronizing rod 1106, and a second conical wheel 1107. All 07 are symmetrically arranged. The synchronizing rod 1106 is movably connected to the inside of the moving groove 15 through bearings. The second conical wheel 1107 is fixedly connected to one end of the synchronizing rod 1106. The synchronizing rod 1106 passes through the moving block 1105 and is threadedly connected to the moving block 1105. The moving block 1105 is movably connected to the inside of the moving groove 15. The two ends of the connecting rod 1104 are movably connected to the moving block 1105 through bearings. The first conical wheel 1003 meshes with the second conical wheel 1107. The control rod 1006 passes through the second rack 1103 and is threadedly connected to the second rack 1103. The bottom ends of the first rack 1005 and the second rack 1103 are movably connected to the bottom end of the moving frame 7.

[0048] The servo motor 9 controls the rotation of the control lever 8, thereby causing the moving frame 7 to move longitudinally within the base plate 6. This adjusts the longitudinal position of the massage element 2 to accommodate different positions of the user's waist, thus increasing the coverage area of ​​the waist massage. Subsequently, the servo motor 14 is activated, driving the worm gear 1008 to rotate, which in turn drives the worm wheel 1007 to rotate, causing the control lever 1006 to rotate synchronously. Since the control lever 1006 is threadedly connected to the rack 1005, the two racks 1005 are moved away from each other, driving the gear 1004 to rotate. This causes the cone wheel 1003, drive lever 1001, and extension lever 1002 to rotate synchronously, controlling the horizontal movement of the massage element 2. This increases the horizontal coverage area of ​​the massage element 2, making the massage more effective for users with wide waists.

[0049] like Figure 1 , Figure 2 and Figure 9As shown, the support mechanism 12 includes a first connecting rod 1201, a second connecting rod 1202, a movable rod 1203, and a moving rod 1204. The first connecting rod 1201 and the second connecting rod 1202 are arranged in a linear array. The movable rod 1203 passes through the opposite sides of the first connecting rod 1201 and the second connecting rod 1202, and both the first connecting rod 1201 and the second connecting rod 1202 are movably connected to the movable rod 1203. The other end of the first connecting rod 1201 is movably connected to the support block 13 via a pivot, and the other end of the second connecting rod 1202 is movably connected to one side of the moving rod 1204 via a pivot. The support mechanism 12 also includes a fixed rod 1205, a plug rod 1206, and a return spring 1207. The fixed rod 1205 is fixedly connected to the lumbar pillow 1. On the back side, a number of insertion holes 16 are provided on one side of the fixed rod 1205, and the insertion holes 16 are arranged in a linear array. The insertion rods 1206 are arranged in a linear array. The insertion rods 1206 are all fixedly connected to one side of the moving rod 1204, and the insertion rods 1206 are respectively adapted to the insertion holes 16. The return springs 1207 are arranged in a linear array, and the return springs 1207 are respectively fixedly connected to the inside of the insertion holes 16. One end of the insertion rod 1206 abuts against one end of the return spring 1207. An adjusting rod 17 is movably connected to the middle position of the fixed rod 1205 through a bearing. One end of the adjusting rod 17 is fixedly connected to a knob 18. The adjusting rod 17 passes through the moving rod 1204, and the adjusting rod 17 and the moving rod 1204 are threadedly connected.

[0050] Because conical wheel 1003 and conical wheel 1107 mesh, they drive synchronous rod 1106 to rotate inside moving groove 15. Synchronous rod 1106 is threadedly connected to moving block 1105, causing connecting rod 1104 to move inside moving frame 7, thereby driving massage component 2 to move horizontally. Gear 1102 moves synchronously. Because rack 1103 is threadedly connected to control rod 1006, and gear 1102 meshes with rack 1103, and rack 1103 moves faster than massage component 2, gear 1102 rotates during movement, thereby driving massage component 2 to rotate synchronously. As the two massage components 2 move away from each other, the angle between them gradually decreases, allowing the width between them to cover the horizontal area of ​​the user's waist. The massage components 2 fit the waist more closely, ensuring that they can fully press the user's waist.

[0051] Working principle: In use, the lumbar pillow 1 can be fixed to the chair by the strap 3, and items such as mugwort sachets can be placed in front of the lumbar pillow 1 by the elastic pocket 4. The heater 5 heats the user's lumbar spine to enhance the massage effect. Then, the adjustment rod 17 is rotated by the knob 18. Since the adjustment rod 17 is threadedly connected to the moving rod 1204, it controls the moving rod 1204 to move towards the support block 13. The opposite sides of the connecting rod 1201 and the connecting rod 2 1202 rotate around the movable rod 1203, so that the included angle between the connecting rod 1201 and the connecting rod 2 1202 gradually decreases, thereby achieving a protruding effect. At this time, the insertion rod 1206 moves away from the insertion hole 16, and the return spring 1207 is in the insertion hole 16. The extension of the linkage 1201 and 1202 controls the distance between the lumbar pillow 1 and the chair, thus providing more stable support for the lumbar pillow 1 and improving its stability. Subsequently, the servo motor 9 controls the rotation of the control lever 8, causing the moving frame 7 to move longitudinally within the base plate 6, thereby adjusting the longitudinal position of the massage component 2 to accommodate different positions of the user's waist and improve the coverage area of ​​the lumbar massage. Then, by activating the servo motor 14, the worm gear 1008 rotates, which in turn drives the worm wheel 1007 to rotate, causing the control lever 1006 to rotate synchronously. Since the control lever 1006 is threadedly connected to the rack 1005, the two racks... The first 1005 blocks move away from each other, driving the first gear 1004 to rotate, thereby causing the first cone wheel 1003, drive rod 1001, and extension rod 1002 to rotate synchronously. Since the first cone wheel 1003 and the second cone wheel 1107 mesh (Note: The first cone wheels 1003 at both ends of drive rod 1001 move in the same direction, and the two first cone wheels 1003 are located at different positions on the second cone wheel 1107, resulting in opposite rotation directions for the two second cone wheels 1107; if the two moving blocks 1105 are to move in the same direction, the threads on the outer sides of the two synchronizing rods 1106 must be opposite), the synchronizing rod 1106 is driven to rotate inside the moving groove 15, and the synchronizing rod 1106 is threadedly connected to the moving block 1105. The connecting rod 1104 moves inside the moving frame 7, thereby driving the massage piece 2 to move horizontally. The gear 1102 moves synchronously. Since the rack 1103 is threadedly connected to the control rod 1006, and the gear 1102 meshes with the rack 1103, and the moving speed of the rack 1103 is faster than that of the massage piece 2, the gear 1102 rotates during the movement, thereby driving the massage piece 2 to rotate synchronously. As the two massage pieces 2 move away from each other, the angle between the massage pieces 2 gradually decreases, so that the width between the massage pieces 2 can cover the horizontal area of ​​the user's waist, and the massage pieces 2 fit the waist more closely, improving the use effect of the massage pieces 2.
