Description

Technical Field

[0001] This invention relates to the field of auxiliary training for cardiovascular and cerebrovascular diseases, specifically a rehabilitation device for patients with cardiovascular and cerebrovascular diseases. Background Technology

[0002] Patients with cardiovascular and cerebrovascular diseases often experience symptoms such as hemiplegia and limb weakness due to narrowing or even blockage of blood vessels caused by vascular lesions. Therefore, timely intervention and active rehabilitation treatment are necessary for patients with cardiovascular and cerebrovascular diseases.

[0003] Currently, rehabilitation treatment for patients with cardiovascular and cerebrovascular diseases involves limb training. This involves passively moving the large and small joints of the patient's limbs to prevent muscle atrophy around the joints and to aid in later functional recovery. Because patients with cardiovascular and cerebrovascular diseases cannot control their limbs well, passive movement requires frequent intervention from others. To improve the efficiency and convenience of limb training, existing rehabilitation devices are used to control the patient's limbs. However, current technology separates arm and leg training, meaning that the patient's perception of their arms and legs cannot be effectively correlated during training, resulting in poor coordination recovery. Summary of the Invention

[0004] The present invention provides a rehabilitation device for patients with cardiovascular and cerebrovascular diseases, which aims to solve the technical problems mentioned in the background art.

[0005] A technical solution for a rehabilitation device for patients with cardiovascular and cerebrovascular diseases includes: a support base and a seat connected to the support base; further comprising: a rotating wheel rotatably connected to the front side of the support base; foot pedals rotatably connected to the left and right sides of the rotating wheel, the two foot pedals being symmetrically arranged on the rotating wheel with the center point of the rotating wheel as the center point; a drive component fixedly connected to the support base, the drive component being connected to the rotating wheel; a sliding groove fixedly connected to the left and right sides of the seat; a sliding plate slidably connected to the sliding groove; a return spring a fixedly connected between the sliding groove and the sliding plate; a support arm a connected between the seat and the sliding plate, the support arm a being rotatably and slidably connected to the seat, the support arm a being rotatably connected to the sliding plate; a top frame slidably connected to the left and right sides of the seat, the top frame on the same side being fixedly connected to the sliding plate; a return spring b fixedly connected between the seat and the top frame; and two protrusions fixedly connected to the rotating wheel, the two protrusions being symmetrically arranged on the rotating wheel with the center point of the rotating wheel as the center point, the protrusions on the same side contacting the top frame.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: A rehabilitation device for patients with cardiovascular and cerebrovascular diseases, such as... Figures 1-3 As shown, it includes: a support base 1, on which a guide rail 101 in the front-to-back direction is provided; a seat 2 slidably mounted on the support base 1, the seat 2 having a backrest, and a base frame 201 at the bottom of the seat 2, the base frame 201 being slidably connected to the guide rail 101, allowing the seat 2 to slide back and forth on the support base 1; a rotating wheel 3 rotatably mounted on the front side of the support base 1; and foot pedals 31 rotatably mounted on the left and right sides of the rotating wheel 3, the two foot pedals 31 being symmetrically arranged on the rotating wheel 3 with the center point of the rotating wheel 3 as the center point. The foot pedal 31 is provided with a strap a311 for stably connecting the patient's foot to the foot pedal 31; a drive unit 32 is fixedly installed on the support base 1, the drive unit 32 is connected to the rotating wheel 3, and controls the rotation of the rotating wheel 3. The drive unit 32 includes a servo motor 321 installed on the support base 1, sprockets 322 respectively fixedly installed on the shaft of the rotating wheel 3 and the output shaft of the servo motor 321, and a chain 323 wound between the two sprockets 322, the chain 323 meshing with the sprockets 322; The operator assists the patient to sit on the seat 2, places the patient's feet on the foot pedals 31 one on the left and one on the right, and uses straps a311 to fix the patient's feet. The operator starts the servo motor 321, controls the rotating wheel 3 to rotate, and controls the foot pedals 31 to revolve. The foot pedals 31, through their connection to the feet, drive the patient's legs to move alternately, exercising the patient's leg muscles and joints. At the same time, the foot pedals 31 rotate incompletely under the action of the patient's feet, exercising the patient's ankle joints.

[0030] like Figure 1 and Figure 4 As shown, the device includes: sliding grooves 41 fixedly installed on the left and right sides of the seat 2; sliding plates 42 slidably installed on the two sliding grooves 41; return springs a421 fixed between the sliding plates 42 and the sliding grooves 41 on the same left and right sides, the return springs a421 being used to restore the position of the sliding plates 42; and support arms a4 installed between the sliding plates 42 and the seat 2, the support arms a4 being located on the left and right sides of the seat 2, the support arms a4 being provided with straps b401 for stably connecting the patient's upper arm to the support arms a4, guide rods 402 fixed on the upper end of the support arms a4 facing the side of the seat 2, guide grooves 202 being opened on the left and right sides of the backrest of the seat 2, the guide rods 402 sliding in the guide grooves 202, so that the upper end of the support arms a4... The support arm a4 is rotatably and slidably connected to the seat 2. The lower end of the support arm a4 is rotatably connected to the rear end of the sliding plate 42 via a pivot 422. Guide blocks 431 are provided on both the left and right sides of the base frame 201. The top frame 43 is slidably mounted on the two guide blocks 431 respectively. The top frame 43 on the left and right sides is fixedly connected to the sliding plate 42. The return spring b432 is sleeved on the top frame 43. The two ends of the return spring b432 are fixed to the top frame 43 and the support base 1 respectively. The return spring b432 is used to restore the position of the top frame 43. Two protrusions 44 are fixedly mounted on the rotating wheel 3. The protrusions 44 are symmetrically arranged on the rotating wheel 3 with the center point of the rotating wheel 3. The protrusions 44 on the left and right sides are in contact with the top frame 43. After the patient sits on the seat 2, their arms are in contact with the two support arms a4. The patient's upper arms are secured with straps b401. When the drive unit 32 controls the rotating wheel 3 to rotate, it will push the two top frames 43 backward alternately through the protrusion 44. The top frames 43 move backward and push the lower end of the support arm a4 backward through the sliding plate 42. The return springs a421 and b432 deform. At the same time, the guide rod 402 on the support arm a4 slides upward in the guide groove 202 and rotates. That is, the support arm a4 rotates. After the protrusion 44 disengages from the top frame 43, the return springs a421 and b432 restore the position of the sliding plate 42 and the top frame 43. The lower end of the support arm a4 is controlled to move forward to restore its position, and the support arm a4 is rotated back. That is, the two support arms a4 can drive the patient's arms to swing alternately, exercising the muscles and joints of the patient's arms.

[0031] Therefore, by using this device, the movement trajectory of the patient's legs and arms when walking can be controlled, so that the range of motion of the thighs and arms can reach the normal range of motion of the joints as much as possible, preventing muscle atrophy around the joints, and controlling the thighs and arms to perform passive movements synchronously, so as to conduct coordinated training of the legs and arms, enabling the patient to perceive the state of the limbs as a whole when they are moving, promoting the recovery of the patient's nerve function, and improving the overall coordination and balance of the patient's limbs.

[0032] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes: a mounting bracket 51 fixedly mounted on the support base 1, the mounting bracket 51 being located between the rotating wheel 3 and the seat 2, with one on each side, so that when the patient's foot is placed on the footrest 31, the two mounting brackets 51 are respectively located under the patient's leg; an adjusting screw 52 threadedly mounted on the mounting bracket 51, rotating the adjusting screw 52 will change the relative position between the adjusting screw 52 and the mounting bracket 51; a sliding rod 53 slidably mounted on the upper end of the adjusting screw 52; a return spring c55 sleeved on the sliding rod 53, with both ends of the return spring c55 fixed on the sliding rod 53 and the adjusting screw 52 respectively; a mounting plate 54 hingedly mounted on the upper end of the sliding rod 53; and rollers 5 rotatably mounted on the mounting plate 54, with three rollers 5 on each mounting plate 54; Using this device, rotating the adjusting screw 52 adjusts the height of the roller 5 in contact with the patient's leg, causing the sliding rod 53 to slide slightly relative to the adjusting screw 52. The return spring c55 is slightly compressed. Under the action of the return spring c55, the roller 5 is brought into contact with the leg. When the patient's leg is passively moved, the roller 5 will be able to roll relative to the patient's leg, providing rolling massage and promoting blood circulation. The setting of the return spring c55 and the sliding rod 53 allows the roller 5 to change its height according to the position of the leg. The mounting plate 54 allows the roller 5 to change its angle according to the position of the leg, that is, to make the roller 5 in flexible contact with the leg, ensuring the comfort of the roller 5 in contact with the patient's leg.

[0033] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes: a support arm b6 rotatably mounted on the sliding plate 42, the rear end of the support arm b6 being rotatably connected to the sliding plate 42 and the support arm a4 via a rotating shaft 422, and the support arm b6 being provided with a strap c601 for stably connecting the patient's forearm to the support arm b6; a missing gear 61 fixedly mounted on the rear end of the support arm b6, the missing gear 61 being coaxial with the rotating shaft 422; and a rack 62 fixedly mounted on the rear end of the slide groove 41, the missing gear 61 being able to mesh with the rack 62. The patient's forearm is secured by strap c601. When the protrusion 44 moves the sliding plate 42 through the top frame 43, controlling the swing of the support arm a4, the sliding plate 42 will drive the support arm b6 to move backward, so that the missing gear 61 meshes with the rack 62. Then the support arm b6 is rotated, lifting the patient's forearm. When the sliding plate 42 slides forward, the missing gear 61 is reversed, and the support arm b6 rotates back to put the forearm back. That is, the support arm b6 is controlled to swing synchronously with the support arm a4, so that the elbow joint of the arm can be passively moved synchronously, thus expanding the training effect of this device on the patient.

[0034] like Figure 1 , Figure 5 and Figure 10 As shown, it also includes: a movable screw 7 rotatably mounted on the support base 1, the movable screw 7 being threadedly connected to the base frame 201; the top frame 43 includes: a support rod 4301 slidably mounted on the guide block 431, the rear end of the support rod 4301 being fixedly connected to the sliding plate 42; a sleeve rod 4302 fitted onto the front end of the support rod 4301, the rear end of the sleeve rod 4302 fitted onto the support rod 4301 having a groove for deformation of the sleeve rod 4302, and the front end of the sleeve rod 4302... The part contacts the protrusion 44; the threaded ring 4303 is installed at the rear end of the sleeve rod 4302. The inner diameter of the front end of the threaded ring 4303 is larger than the inner diameter of the front end. When the threaded ring 4303 is rotated and slides forward relative to the sleeve rod 4302, the threaded ring 4303 will press the rear end of the sleeve rod 4302 inward and deform it, thus clamping the sleeve rod 4302 onto the support rod 4301 and fixing the relative position between the sleeve rod 4302 and the support rod 4301. Because different patients have different leg lengths, this device may not be suitable for all patients. Therefore, before using this device, rotate the moving screw 7 to change the distance between the seat 2, the rotating wheel 3, and the footrest 31 so that the patient's legs can comfortably use the device when sitting on the seat 2. After completion, rotate the threaded ring 4303 to release the fixation between the sleeve rod 4302 and the support rod 4301, change the relative position between the sleeve rod 4302 and the support rod 4301, and adjust the length of the top frame 43 according to the position of the seat 2 to ensure the normal use of the top frame 43. After adjustment, reverse the threaded ring 4303 to re-fix the sleeve rod 4302 and the support rod 4301.

[0035] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
