Description

Technical Field

[0001] This application relates to the field of rehabilitation training devices, and in particular to a limb rehabilitation training bed. Background Technology

[0002] Health rehabilitation training is an important treatment method to help patients with limb motor dysfunction gradually improve their limb motor function. The health rehabilitation training bed is a type of rehabilitation training device used in health rehabilitation training. Patients perform limb movement training on the bed. Through training, the range of motion of the patient's limb joints is improved, the coordination and stability of the joints are improved, the limb muscle groups are stimulated, and muscle atrophy is relieved, thereby accelerating the patient's rehabilitation process.

[0003] Chinese patent CN117838479A discloses a limb movement training device for long-term bedridden patients, which has a platform above the bed and height-adjustable hand exercise end and leg exercise end installed on the platform.

[0004] During the use of the above technology, patients can exercise their limbs by pulling the hand and leg exercise ends. However, since most patients are relatively weak at the beginning of the training, they are unable to spontaneously exert force to complete the training, resulting in poor rehabilitation training effect of the above training device and its shortcomings. Utility Model Content

[0005] To address the issue that patients are too weak to spontaneously exert effort to complete training during initial stages, this application provides a limb rehabilitation training bed.

[0006] The limb rehabilitation training bed provided in this application adopts the following technical solution:

[0007] A limb rehabilitation training bed includes a bed frame and a training frame. A hand training rod and a leg training rod are slidably mounted on the training frame along the length of the bed frame. The training frame is equipped with a hand-moving component for driving the hand training rod to slide and a leg-moving component for driving the leg training rod to slide. A first winding wheel is rotatably mounted at both ends of the hand training rod, and a hand pull rope is wound on the first winding wheel. A handle is mounted on the hand pull rope. A hand rope winding component is mounted on the hand training rod to drive the rotation of the first winding wheel. A second winding wheel is rotatably mounted at both ends of the leg training rod, and a leg pull rope is wound on the second winding wheel. A leg binding component is mounted on the leg pull rope to fix the leg pull rope to the patient's leg. A leg rope winding component is mounted on the leg training rod to drive the rotation of the second winding wheel.

[0008] By adopting the above technical solution, when the patient needs to train their hands, the hand rope winding device drives the first winding wheel to unwind the hand rope. The patient then grasps the handle, and the hand rope winding device drives the first winding wheel to repeatedly wind and unwind the hand rope, thereby exercising the patient's hand stretching movement. At the same time, the hand movement device drives the hand training rod to slide back and forth along the length of the bed, thereby exercising the patient's hand lifting and lowering movements. When the patient needs to train their legs, the doctor fixes the patient's legs to the leg rope using the leg binding device. Then, the leg rope winding device repeatedly drives the second winding wheel to wind and unwind the rope, thereby exercising the patient's leg lifting movement. At the same time, the leg movement device drives the leg training rod to slide back and forth along the length of the bed, thereby exercising the patient's leg flexion movement. This solves the problem of insufficient strength in the initial rehabilitation training of patients.

[0009] Optionally, the hand-moving component includes a rack mounted on the training frame, a first motor electrically connected to the control system is mounted on the hand training rod, a first gear coaxially mounted on the output shaft of the first motor and meshing with the rack, and a slide rail with a T-shaped cross-section is mounted on the hand training rod, the length direction of the slide rail being parallel to the length direction of the rack, and the hand training rod slidingly engaging with the slide rail.

[0010] By adopting the above technical solution, the control system starts the first motor, the output shaft of the first motor drives the first gear to rotate, the rotation of the first gear and the reaction force of the rack, and under the guidance of the slide rail, the hand training rod slides back and forth along the length of the rack.

[0011] Optionally, the leg movement component includes a second motor disposed on the leg training rod and electrically connected to the control system. A second gear that meshes with the rack is coaxially disposed on the output shaft of the second motor, and the leg training rod slides in cooperation with the slide rail.

[0012] By adopting the above technical solution, the control system starts the second motor, the output shaft of the second motor drives the second gear to rotate, and the reaction force between the rotation of the second gear and the rack, along with the guidance of the slide rail, causes the leg training bar to slide back and forth along the length of the rack.

[0013] Optionally, the hand winding component includes a third motor and a first reduction gearbox mounted on the hand training bar. The third motor is electrically connected to the control system, the output shaft of the third motor is connected to the input end of the first reduction gearbox, and the first winding wheel is connected to the output end of the first reduction gearbox.

[0014] By adopting the above technical solution, the control system starts the third motor, and the output shaft of the third motor drives the first winding wheel to rotate through the first reduction gearbox, thereby achieving the effect of slowly rotating the first winding wheel, which helps to reduce the possibility of causing further harm to the patient.

[0015] Optionally, the leg strap includes an arc plate disposed on the leg pull rope, with straps at both ends of the arc shape of the arc plate, one of the straps having a hook and loop fastener side and the other strap having a fleece side.

[0016] By adopting the above technical solution, the doctor places the arc plate on the patient's leg, and then uses the hook and loop sides of the strap to fix the patient's leg to the leg strap. At the same time, the strap has a large contact area with the patient's leg, which helps to reduce the possibility of causing marks on the patient's leg.

[0017] Optionally, the leg winding component includes a fourth motor and a second reduction gearbox mounted on the leg training bar. The fourth motor is electrically connected to the control system, the output shaft of the fourth motor is connected to the input end of the second reduction gearbox, and the second winding wheel is connected to the output end of the second reduction gearbox.

[0018] By adopting the above technical solution, the control system starts the fourth motor, and the output shaft of the fourth motor drives the second winding wheel to rotate slowly through the second reduction gearbox, thereby realizing the slow lifting and lowering of the patient's legs, thus reducing the possibility of causing further damage to the patient.

[0019] Optionally, a backplate is rotatably mounted on the bed, and an electric cylinder is hinged between the backplate and the bed, the electric cylinder being electrically connected to the control system.

[0020] By adopting the above technical solution, the control system starts the electric cylinder, the piston rod of the electric cylinder extends, and the back plate rotates and opens, thereby facilitating the patient to sit up for training.

[0021] Optionally, the bottom of the bed is provided with multiple casters, and the bed is detachably mounted on the training frame.

[0022] By adopting the above technical solution, doctors can easily move patients on the bed.

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

[0024] 1. When the patient needs to train their hands, the hand rope winding device drives the first winding wheel to unwind the hand rope. Then the patient grabs the handle, and the hand rope winding device drives the first winding wheel to repeatedly wind and unwind the hand rope, thereby exercising the stretching movement of the patient's hands. At the same time, the hand movement device drives the hand training rod to slide back and forth along the length of the bed, thereby exercising the lifting and lowering movements of the patient's hands.

[0025] 2. When patients need to train their legs, the doctor uses a leg binder to fix the patient's legs to the leg pull rope. Then, the leg rope winding device continuously and repeatedly drives the second winding wheel to wind and unwind the rope, thereby exercising the patient's leg lifting movement. At the same time, the leg movement device drives the leg training rod to slide back and forth along the length of the bed, thereby exercising the patient's leg bending movement, thus solving the problem of insufficient strength in the initial rehabilitation training of patients.

[0026] 3. The control system activates the electric cylinder, which extends its piston rod, causing the backplate to rotate and open, thus facilitating the patient to sit up for training. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0031] This application discloses a limb rehabilitation training bed.

[0032] Reference Figure 1 A limb rehabilitation training bed includes a bed body 1 and a training frame 2 with an L-shaped cross-section. Multiple casters 17 are bolted to the bottom of the bed body 1. A base 18 is arranged next to the bed body 1 and fixed to the floor. The training frame 2 is vertically slidably arranged on the base 18. A hydraulic cylinder 19 electrically connected to the control system is welded to the base 18. The training frame 2 is welded to the piston rod of the hydraulic cylinder 19. The bed body 1 is bolted to the base 18.

[0033] Reference Figure 1 and Figure 2A backrest 15 is rotatably connected to the bed frame 1. An electric cylinder 16 is hinged between the backrest 15 and the bed frame 1. The electric cylinder 16 is electrically connected to the control system. A hand training rod 3 and a leg training rod 4 are slidably arranged on the training frame 2 along the length of the bed frame 1. A hand movement component 5 that drives the hand training rod 3 to slide and a leg movement component 6 that drives the leg training rod 4 to slide are arranged on the training frame 2.

[0034] The control system activates the electric cylinder 16, and the piston rod of the electric cylinder 16 extends or retracts, thereby controlling the rotation angle of the back plate 15, so as to facilitate the patient to maintain sitting or lying flat, and thus facilitate the patient's targeted rehabilitation training.

[0035] Reference Figure 1 and Figure 2 The hand-moving component 5 includes a rack 51 welded to the training frame 2, and a first motor 52 electrically connected to the control system is bolted to the hand training rod 3. The first motor 52 can be a forward and reverse motor in the prior art. A first gear 53 that meshes with the rack 51 is coaxially welded to the output shaft of the first motor 52. A slide rail 54 with a T-shaped cross section is welded to the hand training rod 3. The length direction of the slide rail 54 is parallel to the length direction of the rack 51.

[0036] Reference Figure 1 and Figure 2 The hand training rod 3 is slidably mounted on the slide rail 54. Both ends of the hand training rod 3 are rotatably connected to the first winding wheel 7. The first winding wheel 7 is wound with a hand pull rope 8, which can be made of high-rigidity steel wire rope. The hand pull rope 8 is attached to the handle 9. The hand training rod 3 is provided with a hand rope winding component 10 that drives the first winding wheel 7 to rotate.

[0037] Reference Figure 1 and Figure 2 The hand-wrapping component 10 includes a third motor 101 and a first gearbox 102 attached to the hand training rod 3. The third motor 101 can be a forward and reverse motor in the prior art. The third motor 101 is electrically connected to the control system. The output shaft of the third motor 101 is connected to the input end of the first gearbox 102. The first winding wheel 7 is connected to the output end of the first gearbox 102.

[0038] When the patient needs to train their hands, the control system starts the third motor 101. The output shaft of the third motor 101 drives the first winding wheel 7 to rotate in the opposite direction through the first reduction gearbox 102, so that the first winding wheel 7 unwinds the hand pull rope 8. Then the patient grabs the handle 9, and then the control system starts the third motor 101 again.

[0039] The output shaft of the third motor 101 drives the first winding wheel 7 to rotate forward through the first reduction gearbox 102, causing the first winding wheel 7 to wind up the hand rope 8, pulling the patient's hand up. Then the third motor 101 continuously repeats the forward and reverse rotation, causing the first winding wheel 7 to continuously wind up and unwind the hand rope 8, thereby exercising the stretching movement of the patient's hand.

[0040] The control system starts the output shaft of the first motor 52 to continuously rotate in the forward and reverse directions. The output shaft of the first motor 52 drives the first gear 53 to rotate. The rotation of the first gear 53 and the reaction force with the rack 51, along with the guidance of the slide rail 54, cause the hand training rod 3 to slide back and forth along the length of the rack 51, thereby exercising the patient's hand lifting and lowering movements.

[0041] Reference Figure 1 and Figure 2 The leg movement component 6 includes a second motor 61 that is bolted to the leg training rod 4 and electrically connected to the control system. The second motor 61 can be a forward and reverse motor as in the prior art. A second gear 62 that meshes with a rack 51 is coaxially welded to the output shaft of the second motor 61. The leg training rod 4 is slidably sleeved on the slide rail 54. Both ends of the leg training rod 4 are rotatably connected to a second winding wheel 11. A leg pull rope 12 is wound on the second winding wheel 11.

[0042] Reference Figure 1 and Figure 2 A leg-binding device 13 is arranged on the leg pull rope 12. The leg-binding device 13 is used to fix the leg pull rope 12 to the patient's leg. The leg-binding device 13 includes an arc plate 131 with a C-shaped cross-section that is attached to the leg pull rope 12. Both ends of the arc plate 131 are glued with straps 132. One strap 132 has a Velcro hook side 133 sewn on it, and the other strap 132 has a Velcro fleece side 134 sewn on it.

[0043] Reference Figure 1 and Figure 2 The leg training bar 4 is equipped with a leg winding member 14 that drives the second winding wheel 11 to rotate. The leg winding member 14 includes a fourth motor 141 and a second reduction gearbox 142 that are attached to the leg training bar 4. The fourth motor 141 can be a forward and reverse motor in the prior art. The fourth motor 141 is electrically connected to the control system. The output shaft of the fourth motor 141 is connected to the input end of the second reduction gearbox 142. The second winding wheel 11 is connected to the output end of the second reduction gearbox 142.

[0044] When a patient needs to train their legs, the doctor uses the hook side 133 and the loop side 134 of the Velcro to fix the patient's legs to the arc plate 131. Then the control system starts the fourth motor 141. The output shaft of the fourth motor 141 drives the second winding wheel 11 to rotate slowly through the second reduction gearbox 142, so that the second winding wheel 11 continuously repeats the process of winding and unwinding the leg rope 12, thereby exercising the patient's leg lifting movement.

[0045] The control system starts the second motor 61. The output shaft of the second motor 61 drives the second gear 62 to rotate. The reaction force between the rotation of the second gear 62 and the rack 51, along with the guidance of the slide rail 54, causes the leg training rod 4 to slide back and forth along the length of the rack 51. The leg pull rope 12 pulls the patient's leg to move back and forth continuously, thereby exercising the patient's leg bending movement.

[0046] The implementation principle of a limb rehabilitation training bed in this application embodiment is as follows: the control system starts the electric cylinder 16, and the piston rod of the electric cylinder 16 extends or retracts, thereby controlling the rotation angle of the back panel 15, so as to facilitate the patient to maintain sitting or lying flat, and thus facilitate the patient's targeted rehabilitation training.

[0047] When the patient needs to train their hands, the control system starts the third motor 101. The output shaft of the third motor 101 drives the first winding wheel 7 to rotate in the opposite direction through the first reduction gearbox 102, so that the first winding wheel 7 unwinds the hand pull rope 8. Then the patient grabs the handle 9, and then the control system starts the third motor 101 again.

[0048] The output shaft of the third motor 101 drives the first winding wheel 7 to rotate forward through the first reduction gearbox 102, causing the first winding wheel 7 to wind up the hand rope 8, pulling the patient's hand up. Then the third motor 101 continuously repeats the forward and reverse rotation, causing the first winding wheel 7 to continuously wind up and unwind the hand rope 8, thereby exercising the stretching movement of the patient's hand.

[0049] The control system starts the output shaft of the first motor 52 to continuously rotate in the forward and reverse directions. The output shaft of the first motor 52 drives the first gear 53 to rotate. The rotation of the first gear 53 and the reaction force with the rack 51, along with the guidance of the slide rail 54, cause the hand training rod 3 to slide back and forth along the length of the rack 51, thereby exercising the patient's hand lifting and lowering movements.

[0050] When a patient needs to train their legs, the doctor uses the hook side 133 and the loop side 134 of the Velcro to fix the patient's legs to the arc plate 131. Then the control system starts the fourth motor 141. The output shaft of the fourth motor 141 drives the second winding wheel 11 to rotate slowly through the second reduction gearbox 142, so that the second winding wheel 11 continuously repeats the process of winding and unwinding the leg rope 12, thereby exercising the patient's leg lifting movement.

[0051] The control system starts the second motor 61. The output shaft of the second motor 61 drives the second gear 62 to rotate. The reaction force between the rotation of the second gear 62 and the rack 51, along with the guidance of the slide rail 54, causes the leg training rod 4 to slide back and forth along the length of the rack 51. The leg pull rope 12 pulls the patient's leg to move back and forth continuously, thereby exercising the patient's leg bending movement.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
