Description

Technical Field

[0001] This invention specifically relates to a lumbar spine care device for rehabilitation. Background Technology

[0002] Patients with various blood disorders such as leukemia, aplastic anemia, and multiple myeloma commonly experience lumbar discomfort and lumbar spine problems. Due to weakened immunity and abnormal hematopoietic function, these patients often require prolonged bed rest and reduced activity. Prolonged bed rest can lead to poor blood circulation in the lumbar region, persistent atrophy and stiffness of the back muscles, and conditions like multiple myeloma can directly damage the lumbar vertebrae, causing bone destruction, vertebral pain, and intervertebral disc compression and deformation. In severe cases, this can result in limited lumbar mobility and persistent aching and distending pain. Such lumbar spine injuries and strains not only exacerbate the patient's physical suffering but also affect the quality of bed rest and the recovery process, hindering the prognosis and rehabilitation of blood disorders. Therefore, targeted rehabilitation care for the lumbar spine is necessary.

[0003] For example, Chinese invention patent CN108451690B discloses a lumbar spine rehabilitation traction bed. This traction bed features a traction frame installed on the bed frame near the end of the bed. This frame consists of a pair of weighted arms and a pair of traction roller arms that rotate with a central axis. The traction force is adjusted by weights and counterweights connected to the weighted arm rollers. A handle drives the central axis to rotate, and a pair of support plates support the weighted arm rollers, facilitating adjustment of the number of counterweights. This design is not only simple and inexpensive, but also reduces operational difficulty without affecting the traction effect, allowing for single-person supervision and operation. Another example is Chinese invention patent CN106963611B, which discloses a lumbar spine massage and rehabilitation device. This device uses a motor to drive a cam and a microcontroller to control an airbag assembly to achieve lumbar spine massage and rehabilitation. It can also provide a heat therapy effect, thus helping lumbar spine patients recover quickly.

[0004] However, simple massage devices can only relax and soothe the superficial muscles of the lower back, and cannot provide traction and stretching to the vertebrae and intervertebral discs. This makes it difficult to improve core issues such as lumbar compression and vertebral misalignment caused by prolonged bed rest and bone lesions. Conversely, traction devices can only perform lumbar traction correction, but cannot relax the lumbar muscles strained from prolonged bed rest; muscle tension can negatively hinder the traction rehabilitation effect. Existing equipment cannot freely switch between and coordinate massage and traction nursing modes. Patients with weak constitutions and intolerance to frequent equipment changes and complex operations find it difficult to adapt a single nursing method to the specific needs of hematology patients for lumbar spine rehabilitation, resulting in significantly reduced lumbar spine care effectiveness and prolonged recovery periods for lumbar complications. Therefore, a rehabilitation lumbar spine care device is proposed to address these problems. Summary of the Invention

[0005] Therefore, it is necessary to provide a rehabilitation lumbar spine care device to address the problem that most existing lumbar spine care devices only have massage or traction functions and cannot freely switch between the two care modes, resulting in a decrease in care effectiveness and reduced patient rehabilitation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lumbar spine care device for rehabilitation, comprising: The seat plate has a fixed backrest hinged to its end, and the backrest has a through groove. A switching frame is slidably disposed on the back of the cushion and connected to the seat plate via a drive mechanism to convert the relative movement of the seat plate and the cushion into driving the switching frame to slide. The traction component is longitudinally slidable on the cushion and provides support under the patient's armpits; The massage component is longitudinally slidable within the through groove and extends out of the through groove when the seat plate and the backrest are rotated to the same plane; and A switching drive mechanism is provided on the switching frame to drive the traction component to slide back and forth when the seat plate and the backrest are in a perpendicular state, and to drive the massage component to slide back and forth when the seat plate and the backrest are rotated to the same plane.

[0007] In one embodiment, the end of the seat plate is also provided with an auxiliary support leg, and a first threaded knob is screwed onto the auxiliary support leg. When the seat plate and the backrest are in a perpendicular state, the first threaded knob passes through the end of the backrest.

[0008] In one embodiment, the drive mechanism includes: A slider is slidably disposed on one side of the cushion and is provided with a drive post; An inclined track is arranged on the switching frame, and both ends of the inclined track are connected to straight tracks. The drive column is engaged within one set of straight tracks. A propulsion component, disposed on the auxiliary support leg and connected to the slider, converts the relative motion between the seat plate and the cushion into driving the slider to slide.

[0009] In one embodiment, the propulsion component includes: A push rod is disposed at the end of the auxiliary support leg; and The connecting rod is hinged at one end to the push rod and at the other end to the slider.

[0010] In one embodiment, the traction assembly includes: The underarm support is provided in two sets. The cushion has two sets of mounting slots. The two sets of underarm supports are slidably installed in the two sets of mounting slots respectively, and the two sets of underarm supports are fixedly connected. A sliding frame, slidably disposed on one side of the cushion and slidably connected to the underarm support; and The second threaded knob has one end rotatably connected to the sliding frame, and the other end screwed to the underarm support.

[0011] In one embodiment, a support block is provided at the bottom of the seat plate, and a support pad is provided on one side of the underarm support. When the seat plate and the backrest are rotated to the same plane, the end faces of the support block and the support pad are on the same plane.

[0012] In one embodiment, the massage component includes: A linkage frame is slidably disposed on one side of the cushion along the extension direction of the through groove; and The massage frame is slidably mounted on the linkage frame in a direction perpendicular to the backrest, and the massage frame is equipped with multiple sets of rotatable massage rollers.

[0013] In one embodiment, a push plate is provided on one side of the massage frame, and an inclined groove is provided on the push plate. A linkage rod is provided on the switching frame, and the linkage rod is slidably engaged in the inclined groove. The length of the linkage rod is not less than the sliding stroke of the switching frame.

[0014] In one embodiment, the switching drive mechanism includes: The push frame is slidably mounted on the switching frame; An abutment rod is provided at the bottom of the sliding frame and can abut against the push frame when the seat plate and the cushion are in a vertical state; The receiving frame is C-shaped and arranged on the linkage frame; An extension rod is mounted on the push frame, and a linkage post is provided on one side of it. After the switching frame slides, the push frame disengages from the abutment rod, and the linkage post slides and engages with the inner side of the receiving frame; and A power unit is mounted on the switching frame and connected to the pusher frame to drive the pusher frame to slide back and forth.

[0015] In one embodiment, the power assembly includes: The drive motor is fixedly mounted on one side of the switching frame; The worm gear is rotatably mounted on the switching frame and is connected to the output shaft of the drive motor via a coupling; A worm gear, rotatably mounted on the switching frame and meshing with the worm, has a control post eccentrically mounted on it; and A sliding frame is fixedly mounted on the pusher, and the control column is slidably engaged within the sliding frame.

[0016] Compared with the prior art, the present invention has at least the following advantages: The backrest cushion in this device can rotate along the end of the seat. The angle between the seat and the backrest cushion serves as the switching trigger. A drive mechanism converts the relative rotation of the seat and cushion into sliding power for the switching frame, enabling precise and automatic switching between two care modes. When the seat and backrest cushion are perpendicular, the device drives the traction component to slide back and forth, providing lumbar traction care through underarm support, stretching the intervertebral space and relieving lumbar compression. When both rotate to the same plane, the massage component automatically extends and reciprocates, providing lumbar massage care, relaxing lumbar muscles, and clearing meridians. Integrating traction and massage functions, this device requires no equipment changes or manual mode adjustments. The care mode can be freely switched according to the patient's posture, adapting to different rehabilitation scenarios such as sitting and lying positions. It balances lumbar skeletal traction correction with lumbar muscle relaxation and repair, overcoming the limitations of single care modes, comprehensively improving lumbar rehabilitation conditions, effectively enhancing rehabilitation quality, and shortening the patient's rehabilitation cycle.

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Example: Please see Figures 1 to 3 The present invention provides a lumbar spine care device for rehabilitation, including a seat plate 1, a fixed backrest 4 hinged to the end of the seat plate 1, an auxiliary support leg 2 provided at the end of the seat plate 1, and a first threaded knob 5 screwed onto the auxiliary support leg 2. When the seat plate 1 and the backrest 4 are in a vertical state, the first threaded knob 5 passes through the end of the backrest 4.

[0024] When in use, the patient can sit on the seat 1 for rehabilitation when the seat 1 and backrest 4 are perpendicular. The positions of the seat 1 and backrest 4 are fixed by the first threaded knob 5, and the auxiliary support legs 2 provide additional support to prevent the device from tipping over. The backrest 4 can be released by turning the first threaded knob 5, and then rotated so that it is level with the seat 1, allowing the patient to lie on the device for rehabilitation.

[0025] Please see Figures 2 to 4 In this embodiment, a switching frame 16 is slidably mounted on the back of the cushion 4. The switching frame 16 is connected to the seat plate 1 via a drive mechanism to convert the relative movement between the seat plate 1 and the cushion 4 into the sliding of the switching frame 16. The drive mechanism includes a slider 6 slidably mounted on one side of the cushion 4, a drive column 7 mounted on the slider 6, and an inclined track 17 mounted on the switching frame 16. Both ends of the inclined track 17 are connected to straight tracks 18. The drive column 7 is engaged within one set of straight tracks 18. The auxiliary support leg 2 is equipped with a propulsion assembly connected to the slider 6. The propulsion assembly converts the relative movement between the seat plate 1 and the cushion 4 into the sliding of the slider 6. The propulsion assembly includes a push rod 3 mounted at the end of the auxiliary support leg 2. One end of the connecting rod 8 is hinged to the push rod 3, and the other end is hinged to the slider 6.

[0026] During the rotation of the cushion 4, the connecting rod 8 can push the slider 6 to slide on one side of the cushion 4, thereby controlling the sliding of the drive column 7. During the movement of the drive column 7, it can control the sliding of the switching frame 16 by cooperating with the inclined track 17, and lock the position of the switching frame 16 by cooperating with the straight track 18, so that the switching frame 16 can be automatically controlled to slide when switching the state of the cushion 4.

[0027] Please see Figure 2 , 3 5. In this embodiment, a traction component for supporting the patient's armpit is longitudinally slidable on the cushion 4. The traction component includes two sets of armpit supports 13. Two sets of mounting grooves 9 are provided on the cushion 4. The two sets of armpit supports 13 are slidably disposed in the two sets of mounting grooves 9 respectively. The two sets of armpit supports 13 are fixedly connected. A sliding frame 11 is slidably disposed on one side of the cushion 4. The sliding frame 11 is slidably connected to the armpit supports 13. One end of the second threaded knob 14 is rotatably connected to the sliding frame 11, and the other end is screwed to the armpit supports 13.

[0028] When the backrest 4 is in an upright position, the sliding frame 11 can be controlled to slide longitudinally back and forth, causing the two sets of underarm supports 13 to slide back and forth vertically. When the patient sits on the seat board 1, they place their arms on the underarm supports 13. The sliding of the underarm supports lifts the patient's upper body, and the patient's own weight provides traction to the lumbar spine, thereby stretching the intervertebral space and relieving lumbar compression. The initial height of the underarm supports 13 can be adjusted by rotating the second threaded knob 14 according to the patient's height to accommodate patients of different body types.

[0029] Please see Figure 1 , 6 7. In this embodiment, the cushion 4 has a through groove 34, and a massage component is slidably disposed within the through groove 34. The massage component extends out of the through groove 34 when the seat plate 1 and the cushion 4 rotate to the same plane. A support block 10 is disposed at the bottom of the seat plate 1, and a support pad 15 is disposed on one side of the underarm support 13. When the seat plate 1 and the cushion 4 rotate to the same plane, the end faces of the support block 10 and the support pad 15 are on the same plane. The massage component includes a linkage frame 28 slidably disposed on one side of the cushion 4 along the extension direction of the through groove 34. A massage frame 32 is slidably disposed on the linkage frame 28 in a direction perpendicular to the cushion 4. The massage frame 32 is provided with multiple sets of rotatable massage wheels 33. A push plate 30 is disposed on one side of the massage frame 32. An inclined groove 31 is disposed on the push plate 30. A linkage rod 19 is disposed on the switching frame 16. The linkage rod 19 is slidably engaged in the inclined groove 31, and the length of the linkage rod 19 is not less than the sliding stroke of the switching frame 16.

[0030] When the backrest 4 is in a vertical position, the massage frame 32 is in a retracted position to avoid interfering with the traction rehabilitation movements. When the backrest 4 is switched to a horizontal position, the entire device can be supported by the cooperation of the support block 10 and the support pad 15, so that the components in the back area of ​​the backrest 4 are not interfered with or blocked by the support surface. When the backrest 4 is switched to a horizontal position, the switching frame 16 slides laterally, which drives the linkage rod 19 to slide laterally. Through the cooperation of the linkage rod 19 and the inclined groove 31, the massage frame 32 slides on the linkage frame 28, so that the massage frame 32 slides out of the through groove 34. By controlling the linkage frame 28 to slide back and forth, the massage rollers 33 on the massage frame 32 can massage the muscles on both sides of the patient's lumbar spine to relax the lumbar muscles and unblock the meridians.

[0031] Please see Figures 5 to 7In this embodiment, the switching frame 16 is equipped with a switching drive mechanism. This mechanism drives the traction component to slide back and forth when the seat plate 1 and the backrest 4 are in a perpendicular state, and drives the massage component to slide back and forth when the seat plate 1 and the backrest 4 rotate to the same plane. The switching drive mechanism includes a pusher 25 slidably mounted on the switching frame 16. A contact rod 12 is provided at the bottom of the sliding frame 11. The contact rod 12 can contact the pusher 25 when the seat plate 1 and the backrest 4 are in a perpendicular state. A C-shaped receiving frame 29 is provided on the linkage frame 28. An extension rod 26 is provided on the pusher 25. A linkage column 27 is provided on one side of the extension rod 26. After the switching frame 16 slides, the pusher 25 disengages from the contact rod 12, and the linkage column 27 slides into the inner side of the receiving frame 29. A power component connected to the pusher 25 is provided on the switching frame 16, driving the pusher 25 to slide back and forth.

[0032] The power assembly includes a drive motor 20 fixedly mounted on one side of the switching frame 16, a worm gear 21 rotatably mounted on the switching frame 16, the worm gear 21 being connected to the output shaft of the drive motor 20 via a coupling, a worm wheel 22 rotatably mounted on the switching frame 16, the worm wheel 22 meshing with the worm gear 21, a control post 23 eccentrically mounted on the worm wheel 22, and a slide frame 24 fixedly mounted on the push frame 25, with the control post 23 slidably locked inside the slide frame 24.

[0033] The drive motor 20 can be started to drive the worm gear 21 to rotate, thereby causing the eccentrically positioned control column 23 to move circumferentially. During the movement, the control column 23 can drive the push frame 25 to slide back and forth on the switching frame 16 through cooperation with the sliding frame 24. When the seat plate 1 and the backrest 4 are perpendicular, the push frame 25 can abut against the abutment rod 12, thereby controlling the sliding frame 11 to slide back and forth as a whole for traction rehabilitation. When the seat plate 1 and the backrest 4 are on the same horizontal plane, the switching frame 16 slides laterally, causing the linkage column 27 to slide into the inner side of the C-shaped receiving frame 29. During the back and forth sliding process, the push frame 25 can push the linkage frame 28 and the massage frame 32 to slide back and forth through the linkage column 27 for massage rehabilitation.

[0034] Specific usage and beneficial effects of the present invention: The backrest 4 in this device can rotate along the end of the seat plate 1. The angle between the seat plate 1 and the backrest 4 serves as the switching trigger condition. A drive mechanism converts the relative rotation of the seat plate 1 and the backrest 4 into the sliding power of the switching frame 16, enabling precise and automatic switching between two care modes. When the seat plate 1 and the backrest 4 are perpendicular, the device drives the traction component to slide back and forth, providing lumbar traction care through underarm support, stretching the intervertebral space and relieving lumbar compression. When both rotate to the same plane, the massage component automatically extends and reciprocates, providing lumbar massage care, relaxing lumbar muscles, and clearing meridians. Integrating traction and massage functions, it requires no equipment replacement or manual mode adjustment. The care mode can be freely switched according to the patient's posture, adapting to different rehabilitation scenarios such as sitting and lying positions. It balances lumbar skeletal traction correction with lumbar muscle relaxation and repair, overcoming the limitations of a single care mode, comprehensively improving lumbar rehabilitation conditions, effectively enhancing rehabilitation quality, and shortening the patient's rehabilitation cycle.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
