Technical Field
[0001] The present invention relates to the technical field of rehabilitation devices, and particularly relates to a rehabilitation assistance device for cerebrovascular diseases. Background Art
[0002] As one of the main causes of disability and death among adults worldwide, cerebrovascular diseases are characterized by high incidence, high disability rate, and high recurrence rate. According to statistics from the World Health Organization (WHO), approximately 15 million people worldwide suffer from cerebrovascular diseases each year. Among them, about 50%-70% of the surviving patients will have sequelae such as varying degrees of limb movement disorders, cognitive function impairments, and swallowing difficulties, which seriously affect the quality of life of patients and also bring a heavy burden to families and society. Since patients with cardiovascular and cerebrovascular diseases generally have poor blood circulation in their limbs, it is difficult for them to walk. In some severe cases, they need to stay in bed for a long time, which will increase the severity of the condition. Therefore, enhancing the exercise and activity of the limbs of patients with cardiovascular and cerebrovascular diseases is crucial. During the hospital rehabilitation process, it is difficult for some long-term bedridden patients to complete autonomous limb exercises and activities in bed and can only rely on the assistance of medical staff or family members for limb exercises. However, due to the small range available for patients to exercise in the ward environment, the rehabilitation efficiency is reduced. Summary of the Invention
[0003] Object of the Invention: The object of the present invention is to solve the problem that it is difficult for some long-term bedridden patients to complete autonomous limb exercises and activities in bed and can only rely on the assistance of medical staff or family members for limb exercises. However, due to the small range available for patients to exercise in the ward environment, the rehabilitation efficiency is reduced.
[0004] Technical Solution: A rehabilitation assistance device for cerebrovascular diseases includes a placement plate. A lifting plate is arranged on the upper surface of the placement plate. Fixed plates are symmetrically and fixedly connected to the upper surface of the lifting plate. Placement grooves are formed in the upper surfaces of both fixed plates.
[0005] Furthermore, sliding cavities are symmetrically formed inside the placement plate. Sliding plates are slidably connected to the interiors of both sliding cavities. Adjusting plates are fixedly connected to the opposite sides of both sliding plates. Adjusting handles are arranged above both adjusting plates. The centers of the lower surfaces of both adjusting handles are fixedly connected to screw rods I. The bottom ends of both screw rods I respectively extend to the inner sides of both adjusting plates and are rotatably connected to clamping plates. The opposite sides of both clamping plates are slidably connected to the inner side walls of both adjusting plates.
[0006] Furthermore, a plurality of positioning round holes are formed on the opposite sides of the two adjusting plates. Pulling plates are symmetrically arranged on the front surface and the rear surface of the placing plate. One side of each of the plurality of pulling plates close to the placing plate is fixedly connected with a movable rod. One ends of the plurality of movable rods far away from the plurality of pulling plates respectively extend into the plurality of positioning round holes. Springs are sleeved on the outer side walls of the plurality of movable rods. Two ends of the plurality of springs are respectively fixedly connected with the opposite sides of the placing plate and the outer side walls of the plurality of pulling plates.
[0007] Furthermore, rubber pads are arranged on the upper surfaces of the inner sides of the two adjusting plates and the lower surfaces of the two clamping plates.
[0008] Furthermore, pressing modules are arranged on the inner sides of the two placing grooves.
[0009] Furthermore, a control cavity is integrally formed inside the placing plate and between the two sliding cavities. Vertical grooves are symmetrically formed on the upper surface inside the control cavity. A movable plate is slidably connected inside the sliding cavity. A motor is fixedly connected to the rear surface inside the control cavity. The front end of the output shaft of the motor is fixedly connected with a first turntable.

The front side of the upper surface of the movable plate and inside the two vertical grooves are both rotationally connected with a support rod through a rotating shaft. The rear ends of the two support rods are rotationally connected to the rear surface of the lower surface of the lifting plate through a rotating shaft.
[0010] Furthermore, limiting plates are fixedly connected to the front side of the two second turntables on the left side and the right side inside the control cavity.
[0011] Furthermore, a plurality of guide rods are commonly connected to the front surface and the rear surface inside the control cavity. The outer side walls of the plurality of guide rods are slidably connected with the inside of the movable plate.
[0012] Beneficial effects: By installing structures such as a placing plate and a lifting plate on the hospital bed, the present invention transforms the hospital bed into a rehabilitation training place, effectively solves the problem of small activity range in the ward.

Detailed Description of the Invention
[0015] To make the technical solutions of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
[0016] Embodiment As Figure 1 , Figure 3 and Figure 4 shown, a cerebrovascular disease rehabilitation assistance device is provided, including a placing plate 1. A lifting plate 2 is arranged on the upper surface of the placing plate 1. Fixing plates 3 are symmetrically and fixedly connected to the upper surface of the lifting plate 2. Placing grooves 4 are formed on the upper surfaces of the two fixing plates 3; Inside the placement board 1 and between two sliding cavities 5, a control cavity 16 is integrally formed. Vertically arranged grooves 17 are symmetrically formed on the inner upper surface of the control cavity 16. An active plate 18 is slidably connected inside the sliding cavity 5. A motor 19 is fixedly connected to the rear surface inside the control cavity 16. The front end of the output shaft of the motor 19 is fixedly connected to a first turntable 20. On the rear surface inside the control cavity 16 and on the left and right sides of the motor 19, a second screw rod 22 is rotatably connected through a rotating shaft. The front ends of the two second screw rods 22 are rotatably connected to the front surface inside the control cavity 16. The outer side walls of the two second screw rods 22 are threadedly connected to the inside of the active plate 18. On the rear sides of the outer side walls of the two second screw rods 22, second turntables 23 are fixedly connected. The outer side walls of the two second turntables 23 and the outer side wall of the first turntable 20 are commonly connected by a transmission belt 24. In front of the upper surface of the active plate 18 and inside the two vertically arranged grooves 17, support rods 25 are rotatably connected through rotating shafts. The rear ends of the two support rods 25 are rotatably connected to the rear surface of the lower surface of the lifting plate 2 through rotating shafts; When it is necessary to lift the lower limbs of a bedridden patient, the motor 19 located inside the control cavity 16 is started. The output shaft of the motor 19 drives the first turntable 20 at the front end to rotate. The first turntable 20 transmits power to the second turntables 23 on the outer side walls of the two second screw rods 22 through the transmission belt 24, so that the two second screw rods 22 rotate synchronously. Since the second screw rods 22 are threadedly connected to the inside of the active plate 18, when the second screw rods 22 rotate, they will drive the active plate 18 to slide back and forth inside the sliding cavity 5. The support rods 25 on the front of the upper surface of the active plate 18 and inside the vertically arranged grooves 17, as the active plate 18 slides, through the rotation of the rotating shaft, convert the horizontal movement of the active plate 18 into the up and down movement of the lifting plate 2, so as to realize the lifting or lowering of the lifting plate 2. The patient places the lower limbs in the placement grooves 4 of the two fixing plates 3 on the upper surface of the lifting plate 2, and the fixation and lifting operations of the lower limbs can be completed. By lifting the patient's lower limbs, blood circulation in the legs can be promoted, deep vein thrombosis can be effectively prevented, and complications caused by blood stasis can be avoided. At the same time, it can assist the patient in early passive movement training, help the patient gradually recover the motor perception ability of the lower limbs, and lay a foundation for subsequent active rehabilitation training.
[0017] As Figure 1 shown, pressing modules 15 are arranged on the inner sides of the two placement grooves 4; Through the arranged pressing modules 15, the pressing intensity and frequency can be automatically adjusted according to the patient's rehabilitation stage and physical condition. For patients in the initial stage of rehabilitation, with relatively stiff and sensitive muscles, the system will automatically reduce the pressing intensity and adopt a gentle and slow pressing rhythm to avoid discomfort to the patient. As the patient's rehabilitation progresses and the muscle strength and tolerance increase, the pressing modules 15 will correspondingly increase the pressing intensity and frequency to meet the needs of higher-intensity rehabilitation training and achieve personalized rehabilitation pressing assistance.
[0018] As Figure 1 - Figure 3As shown in the figure, sliding cavities 5 are symmetrically formed inside the placement plate 1. Sliding plates 6 are slidably connected to the inside of the two sliding cavities 5. Adjusting plates 7 are fixedly connected to the opposite sides of the two sliding plates 6. Adjusting handles 8 are arranged above the two adjusting plates 7. At the center of the lower surfaces of the two adjusting handles 8, first screws 21 are fixedly connected. The bottom ends of the two first screws 21 respectively extend to the inner sides of the two adjusting plates 7 and are rotatably connected to clamping plates 9. The opposite sides of the two clamping plates 9 are slidably connected to the inner side walls of the two adjusting plates 7. A plurality of positioning round holes 10 are formed on the opposite sides of the two adjusting plates 7. Pulling plates 11 are symmetrically arranged on the front and rear surfaces of the placement plate 1. Activity rods 12 are fixedly connected to the sides of the plurality of pulling plates 11 close to the placement plate 1. The ends of the plurality of activity rods 12 away from the plurality of pulling plates 11 respectively extend into the interiors of the plurality of positioning round holes 10. Springs 13 are sleeved on the outer side walls of the plurality of activity rods 12. The two ends of the plurality of springs 13 are fixedly connected to the opposite sides of the placement plate 1 and the outer side walls of the plurality of pulling plates 11. First, pull the plurality of pulling plates 11. The activity rods 12 will overcome the elastic force of the springs 13 and be pulled out from the positioning round holes 10 of the adjusting plates 7, making the adjusting plates 7 in a movable state. Then, rotate the adjusting handles 8 to drive the first screws 21 to rotate. The rotation of the first screws 21 pushes the clamping plates 9 to slide on the inner side walls of the adjusting plates 7, thereby changing the distance between the two clamping plates 9. According to the width of the hospital bed, adjust the position of the adjusting plates 7. The sliding plates 6 slide in the sliding cavities 5, driving the adjusting plates 7 to move until the two clamping plates 9 can clamp the two side edges of the hospital bed. Then, release the pulling plates 11. Under the elastic force of the springs 13, the activity rods 12 are inserted back into the corresponding positioning round holes 10 on the adjusting plates 7, fixing the positions of the adjusting plates 7, thus ensuring that the device is tightly connected to the hospital bed without shaking, and being able to provide stable support for the rehabilitation assistance device, preventing the device from shifting or toppling due to the patient's limb movement or the operation of the device itself during use, effectively guaranteeing the safety of the patient during the rehabilitation training process, avoiding accidental injuries caused by the instability of the device. At the same time, the device can adapt to hospital beds of different widths and thicknesses. Whether it is a standard hospital bed commonly seen in hospitals or a non-standard hospital bed used for home care, it can be firmly fixed, greatly expanding the application scenarios of the device, meeting the rehabilitation needs of different patients in different environments, and improving the versatility and practicality of the device.
[0019] As Figure 1 shown, rubber pads 14 are arranged on the upper surfaces of the inner sides of the two adjusting plates 7 and the lower surfaces of the two clamping plates 9. During the fixing process, the rubber pads 14 are in close contact with the surface of the hospital bed. The rough texture on their surfaces significantly increases the friction with the hospital bed. Even if the patient makes large-amplitude limb movements during the rehabilitation training, the rehabilitation assistance device will not easily slide or shift, further enhancing the stability of the fixing.
[0020] As Figure 4 shown, on the left and right inside the control chamber 16 and in front of the two turntables two 23, there are fixed connection limit plates 26; When the motor 19 drives the turntable one 20 to rotate and drives the turntable two 23 and the screw two 22 to operate through the transmission belt 24, the movable plate 18 will slide back and forth in the sliding chamber 5. Through the limit plate 26, it can prevent the movable plate 18 from exceeding the normal sliding range due to the continuous operation of the motor 19 or other unexpected situations, resulting in abnormal force on the connection part between the support rod 25 and the lifting plate 2, and even causing damage to the mechanical structure and affecting the normal use of the instrument.
[0021] As Figure 3 shown, on the front and rear inner surfaces of the control chamber 16, there are a plurality of guide rods 27 connected together. The outer side walls of the plurality of guide rods 27 are slidably connected to the inside of the movable plate 18; When the motor 19 drives the turntable one 20 to rotate, drives the turntable two 23 and the screw two 22 to operate through the transmission belt 24, and makes the movable plate 18 slide back and forth in the sliding chamber 5, through the plurality of guide rods 27 provided, it can effectively prevent the movable plate 18 from shifting, tilting or jamming during the sliding process, and improve the straightness and stability of the movement of the movable plate 18.
[0022] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
