Description

Technical Field

[0001] This utility model relates to the field of rehabilitation technology, and in particular to a rehabilitation stimulation device. Background Technology

[0002] Neurosurgery, a branch of surgery, builds upon surgical treatment by employing unique neurosurgical research methods to study the human nervous system, including the brain, spinal cord, and peripheral nervous system, as well as related appendages. Post-operative rehabilitation stimulation therapy is necessary for many neurosurgical patients. For example, patients with lower limbs requiring rehabilitation stimulation typically rely on nurses to perform cyclical leg curling and extension exercises to provide physical stimulation, thereby activating the patient's damaged or deteriorating bodily systems and promoting functional recovery and improvement. However, rehabilitation training is physically demanding for nurses, making it impossible to provide prolonged training. Furthermore, passively receiving rehabilitation stimulation is detrimental to patients' confidence in overcoming their illness. To address these issues, a rehabilitation stimulation device is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing rehabilitation techniques, such as the cyclical leg bending and stretching exercises that are physically demanding for caregivers and not conducive to helping patients build confidence in overcoming their illness. Therefore, this invention proposes a rehabilitation stimulation device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a rehabilitation stimulation device, including a cushion, on both sides of which a housing is fixedly installed. A toothed plate is slidably disposed on the top of the housing. A grip rod is inserted into the top of both toothed plates. A transmission gear is rotatably installed inside the housing and meshes with the toothed plates. A driven gear is rotatably installed on one side of the transmission gear, and a driven plate is rotatably installed on one side of the driven gear. A driven column is movably installed at one end of the driven plate. The driven column passes through the housing and a connector is installed at its end. A force-bearing plate is installed at the end of the connector.

[0006] Preferably, the two ends of the grip are provided with anti-slip texture.

[0007] Preferably, a directional plate is fixedly installed on the side of the force-bearing plate near the toothed plate.

[0008] Preferably, a stabilizing ring is fixedly installed inside the housing, the stabilizing ring is provided with teeth, and the stabilizing ring meshes with the driven gear.

[0009] Preferably, the seat cushion is provided with a resistance mechanism on its exterior to increase the resistance to the outward movement of the force plate.

[0010] Preferably, the resistance mechanism includes a connecting column and a resistance spring. One end of the connecting column is fixedly installed to one side of the force-bearing plate, and the other end of the connecting column passes through the seat cushion and extends into the interior of the seat cushion. Hooks are fixedly installed on the opposite side of the seat cushion and the force-bearing plate, and the resistance spring is hung on the hook between the seat cushion and the force-bearing plate.

[0011] Preferably, the number of hooks is multiple sets, which are distributed in a mirror-symmetric manner.

[0012] The rehabilitation stimulation device proposed in this utility model has the following advantages: The device allows the patient to pull the lever back and forth, driving the transmission gear to rotate and causing the driven column to extend and retract, enabling the patient's leg to undergo cyclical leg-bending and leg-extending rehabilitation training. This allows the patient to actively engage in rehabilitation stimulation training, reducing the workload of caregivers and boosting the patient's confidence in overcoming the illness. Once the patient's leg can move independently, the connection between the force plate and the driven column is released. The number of resistance springs can then be increased based on the strength of the patient's movements, allowing the patient to continue leg-bending and leg-extending rehabilitation training until complete recovery. This further improves the device's applicability, making it suitable for patients at different stages of recovery. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1

[0020] Reference Figure 1-4 A rehabilitation stimulation device includes a cushion 1, with housings 3 fixedly mounted on both sides of the cushion 1. Toothed plates 8 are slidably mounted on the top of the housings 3. A grip 7 is inserted into the top of both toothed plates 8, connecting the two toothed plates 8 together and allowing them to move synchronously. A transmission gear 11 is rotatably mounted inside the housings 3, meshing with the toothed plates 8. This gear meshing structure primarily reduces the force required for stretching by the patient. The gear transmission uses rolling friction, which has lower friction loss and higher energy transfer efficiency compared to sliding friction. A driven gear 12 is rotatably mounted on one side of the transmission gear 11, and a driven plate 13 is rotatably mounted on one side of the driven gear 12. A driven post 5 is movably mounted on one end of the driven plate 13, and one end of the driven plate 13 is jaw-shaped for the driven post. The movement of column 5 provides ample space. The distance from the connection point between driven column 5 and driven plate 13 to the connection point between driven plate 13 and driven gear 12 is equal to the distance from the connection point of driven plate 13 to the center of transmission gear 11. Driven column 5 passes through housing 3 and is fitted with connector 6 at its end. Force plate 2 is fitted at the end of connector 6. The presence of connector 6 is a necessary condition for force plate 2 and driven column 5 to be interconnected or interact with each other. The angle between force plate 2 and the horizontal plane is 60 degrees. Under normal circumstances, when sitting with legs straight, the angle between the foot and the ground may tilt slightly forward. This is because the calf muscles have a certain tension in a relaxed state, so the foot is not completely perpendicular to the ground. Therefore, for the patient's comfort, force plate 2 is adjusted to a certain tilt angle.

[0021] The two ends of the grip bar 7 are equipped with anti-slip textures, and the surface of the end of the grip bar 7 is made of rubber material to improve the comfort of the patient's grip. The textured surface of the grip bar 7 provides a certain degree of anti-slip properties to ensure a stable grip even when wet or sweaty.

[0022] A directional plate 10 is fixedly installed on the side of the force plate 2 near the toothed plate 1. It is used to place on the lower leg of the patient when the lower limb cannot move. This prevents the leg from falling to the sides instead of upward when the force plate 2 transmits pushing force to the leg, thus preventing the direction of the force from deviating. The directional plate 10 is at an angle of 20 degrees to the horizontal plane. A horizontal directional plate 10 is not conducive to the patient's manual pushing and pulling, and requires more force. With a certain angle, the directional plate 10 not only saves effort, but also makes it easier to assist the patient's immobile leg and bend it better.

[0023] A stabilizing ring 14 is fixedly installed inside the housing 3. The stabilizing ring 14 is provided with teeth and meshes with the driven gear 12. The gear transmission has a stable transmission ratio, that is, the ratio of input speed to output speed is constant. This helps to maintain the stable operation of the mechanical system and reduce the adverse effects caused by speed fluctuations. The stability of the driven gear 12 is improved by the stabilizing ring 14, and it will not be affected by the fluctuation of the transmission gear 11, thereby reducing maintenance costs.

[0024] In practical use, when the patient's lower limbs are initially unable to move independently, the grip bar 7 is first pulled upwards to detach it from the toothed plate 8. Then, the caregiver assists the patient to sit on the cushion 1, placing their legs on the directional plate 10 and their feet against the force plate 2. The grip bar 7 is then reinstalled on the post of the toothed plate 8. The patient then grips the grip bar 7 and pulls it back and forth. The grip bar 7 drives the toothed plate 8 at the bottom to move back and forth. The teeth at the bottom of the toothed plate 8 drive the transmission gear 11 to rotate back and forth. Because the length of the slot at the top of the housing 3 limits the maximum distance the toothed plate 8 can move, the transmission gear 11 will only rotate half a turn clockwise and half a turn counterclockwise. The back and forth rotation of the transmission gear 11 drives the driven gear 12 to rotate back and forth as well. When the driven gear 12 rotates, it drives the end of the driven plate 13 connected to it to rotate as well. Because the driven column 5 is connected to the housing 3, it cannot rotate but can only move back and forth. The driven column 5 is movably connected to the driven plate 13. When the driven gear 12 rotates, it will move the other end of the driven plate 13 back and forth along the horizontal center line between the transmission gear 11 and the ground. The driven plate 13 will then move the driven column 5 back and forth. When the driven column 5 moves, it will move the force plate 2 back and forth. The force plate 2 will provide pushing and pulling forces to the foot, allowing the leg to bend and straighten. At the same time, the directional plate 10, which has a certain angle, assists the patient's immobile leg to bend better, allowing the patient to exert effort for their own body. This not only reduces the workload of nursing staff but also increases the patient's confidence in overcoming the disease by allowing the patient to actively participate in rehabilitation stimulation training.

[0025] Example 2

[0026] The patient's body will gradually recover. Once the patient can move their legs independently, the rehabilitation stimulation device will need to be replaced to strengthen the training and increase stimulation. The need to replace the device also means increased maintenance, storage, and rehabilitation costs. Figure 1-4 As another preferred embodiment of the present invention, based on embodiment 1, it further includes a resistance mechanism provided on the outside of the cushion 1 to increase the resistance of the force plate 2 to move outward.

[0027] The resistance mechanism includes a connecting column 9 and a resistance spring 15. One end of the connecting column 9 is fixedly installed on one side of the force plate 2, and the other end of the connecting column 9 passes through the seat cushion 1 and extends into the interior of the seat cushion 1. A sliding groove is provided inside the seat cushion 1, and the connecting column 9 slides back and forth in the sliding groove inside the 1. The length of the connecting column 9 is greater than the length of the sliding groove to prevent the connecting column 9 from falling out of the sliding groove and thus failing to provide support for the force plate 2. Hooks 4 are fixedly connected to the opposite side of the seat cushion 1 and the force plate 2, and the resistance spring 15 is hung on the hooks 4 between the seat cushion 1 and the force plate 2.

[0028] The hooks 4 are in multiple sets, arranged in a mirror-symmetrical distribution. The multiple sets of symmetrically distributed hooks 4 allow patients to adjust the resistance of the force plate 2 according to their own recovery level.

[0029] In actual use, when the patient's legs can move independently, first disconnect the force plate 2 and driven column 5 by pulling out connector 6. Then, pull up the handle 7 to separate it from the toothed plate 8. Afterward, the patient can choose how many resistance springs 15 to hook onto the corresponding hooks 4 according to their recovery level. Then, sit on the seat cushion 1 with feet on the force plate 2 and lower legs on the directional plate 10. At this time, due to the elasticity of the resistance springs 15, the force plate 2 is close to the seat cushion 1, and the patient is in a bent-leg position. Then, push the force plate 2 with your feet, and the force plate 2 will move forward. The resistance springs 15 will pull the force plate 2 with their elasticity, thus supporting the force plate. The device provides resistance to facilitate better training. Simultaneously, the movement of the force plate 2 causes the connecting column 9 to slide outwards within the seat cushion 1. The connecting column 9 consistently provides support for the force plate 2. Once the leg is fully extended and the effort is released, the force plate 2 loses its pushing force. The resistance spring 15 then exerts a pulling force on the force plate 2 through its elasticity. The force plate 2 then slides back to its initial position within the seat cushion 1 via the connecting column 9. This cycle repeats, allowing the patient to continue leg-bending and leg-extending rehabilitation stimulation training using the device until complete recovery. Furthermore, the resistance spring 15 can be adjusted to accommodate patients at different recovery stages, further improving the device's applicability.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
