Description

Technical Field

[0001] The present invention relates to the technical field of electrotherapy devices, in particular to a lower limb stimulation device for rehabilitation. Background Art

[0002] In the brain disease rehabilitation department, the patient's knee is the most complex joint in the human body. It is one of the few joints in the human body that can only move in one direction. During the patient's knee joint rehabilitation training, pulse stimulation equipment is needed to perform medical stimulation on the muscles around the thigh. High-frequency pulse electrical stimulation therapy, also known as neuromuscular electrical stimulation therapy, mainly stimulates damaged nerves and muscles to produce passive contraction, restore damaged nerve function and promote muscle movement, and also has the effect of treating acute and chronic pain.

[0003] When using pulse stimulation to treat a patient's lower limbs, because there are many parts that need to be stimulated, the patient needs to turn his body frequently during the process, which is inconvenient. In addition, the handheld pulse stimulation device will also consume a lot of physical energy for the user. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a lower limb stimulation device for rehabilitation to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Through the assembly of a support component and a foot pedal, the calf and knee of the patient's lower limb are limited, and the rotating component drives the pulse stimulation device to rotate during the lifting process, and rotational stimulation treatment is performed around the calf and knee, so that the treatment area is more comprehensive, the patient does not need to frequently change the body position, and the patient's pain is alleviated.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a lower limb stimulation device for rehabilitation department, comprising a base, a foot pedal is rotatably connected to the top of the base through a hinge, a support assembly is installed on the outer side of the top of the foot pedal, the support assembly comprises a storage plate, the bottom of the storage plate is fixed to the outer edge of the top of the foot pedal, and an extension plate is slidably inserted inside the storage plate, the storage plate and the extension plate are both arc-shaped, two support rods are symmetrically arranged on the outside of the storage plate, and a foot pad is fixed at the bottom of the support rod, a rotation assembly is provided at the center of the top of the foot pedal, the rotation assembly comprises a moving ring, the moving ring is coaxial with the foot pedal, two limit frames are symmetrically slidably installed on the inner surface of the storage plate, and the limit frame is slidably sleeved on the outer ring surface of the moving ring, a telescopic rod is fixed on the top of the inner ring of the moving ring, and a pulse stimulation device is fixed on the top of the extended end of the telescopic rod, a swivel is rotatably installed inside the foot pedal through a bearing, and the moving ring is transmission-connected to the swivel.

[0006] Furthermore, the support assembly also includes a sliding frame, two sliding frames are symmetrically fixed on the outer surface of the storage plate, and a slide plate is slidably connected inside the sliding frame, the outer surface of the slide plate is rotatably connected to the support rod through a rotating shaft, and a plug-in rack is fixed at the bottom of the support rod, and the plug-in rack is slidably inserted into the base.

[0007] Furthermore, a sponge pad is fixed on the top of the extending plate, a locking bolt is threadedly inserted on the outer surface of the receiving plate, and the inner side of the locking bolt is in compression contact with the extending plate.

[0008] Furthermore, the rotating assembly also includes a winding seat, and the winding seat is equidistantly fixed at the bottom of the movable ring. The winding seat rotates and winds up the steel wire through the winding shaft and the torsion spring, and the bottom of the steel wire is fixedly connected to the rotating ring inside the foot pedal.

[0009] Furthermore, a driving motor is fixed at the center of the bottom circle of the foot pedal, and the output end of the driving motor is fixedly connected to the rotating ring.

[0010] Furthermore, a ball is fixed to the extended end of the telescopic rod, and the ball is located at the front end of the pulse stimulation device. A first spring is sleeved on the surface of the extended end of the telescopic rod, and the other end of the first spring is fixedly connected to the storage end of the telescopic rod.

[0011] Furthermore, a driving wheel is rotatably mounted on the inner top surface of the extending plate via a bearing, and a driving motor is mounted on the extending plate inside the driving wheel, a driven wheel is rotatably mounted on the inner surface of the bottom of the storage plate via a bearing, and two transmission wheels are symmetrically mounted on the inner surface of the top of the storage plate, and belts are sleeved on the outer sides of the transmission wheel, the driving wheel and the driven wheel.

[0012] Furthermore, a slide groove is provided on the inner surface of the storage plate at positions corresponding to the two transmission wheels, and a slider is slidably connected inside the slide groove, the transmission wheel is rotatably mounted on the slider, and a second spring is fixed between the slide groove and the slider.

[0013] Furthermore, limiting rods are fixed on the outer surface of the sliding block corresponding to the two sides of the belt passing through the transmission wheel, and the belt slides through the transmission belt and the limiting rods.

[0014] Furthermore, the limiting frame on one side of the storage plate is rotatably connected to the outer surface of the belt via a transverse rotating shaft, and the limiting frame on the other side of the storage plate is slidably connected to the outer surface of the other side of the belt via a rotating seat.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention maintains the tension of the belt by sliding the two driving wheels along the slide groove following the change in the height of the extension plate. At the same time, the limiting rod on the slider limits the insertion position and the exit position of the belt, so that the wrapping range of the belt on the driving wheel is greater than 180 degrees, thereby ensuring sufficient friction.

[0017] 2. In the present invention, when the extending plate slides and adjusts along the inside of the storage plate, the elastic slider of the second spring slides along the slide groove, the positions of the two transmission wheels change, and the tension of the belt is maintained. One side of the limit frame connected to the belt is fixedly connected, and the other side is slidably connected. The fixedly connected side can be simply understood as the limit frame can move in the vertical direction together with the belt. Although the moving trajectory of the belt will tilt when it bypasses the transmission wheel during this process, it moves in the vertical direction as a whole. During this process, the limit frame fixedly connected to the belt can slide along the inner surface of the storage plate through the rotation of the rotating shaft, and maintains the same curvature as the inner surface of the storage plate, thereby maintaining the clamping effect on the moving ring.

[0018] 3. The present invention can contact the patient's calf skin through the position of the ball, and through the elastic force of the first spring on the telescopic rod, the pulse stimulation device is kept at a certain distance from the patient's skin at all times, thereby ensuring the stimulation treatment effect.

[0019] 4. The present invention drives the movable ring to rotate synchronously through the connection of the steel wire. Since the movable ring is slidably connected to the limit frame, when the limit frame moves in the vertical direction, it will pull the movable ring to move upward. At this time, the winding seat unwinds the steel wire. Because the steel wire has a certain hardness, when the rotating ring rotates, it can drive the movable ring to rotate synchronously through the cooperation of multiple groups of steel wires, so as to realize the lifting and surrounding stimulation treatment around the calf by the pulse stimulation device. Because the patient's foot is on the foot pedal and the calf is located inside the movable ring, the movement of the movable ring and the unwinding of the steel wire will not be restricted by the patient's legs.

[0020] 5. The extending plate of the present invention can be pulled out along the inside of the storage plate, and its length can be limited by a locking bolt. The sponge pad on the top of the extending plate can contact the bottom of the patient's thigh at the rear end of the knee to support the patient's legs. In this process, if the patient can meet the treatment method of upright calf, the legs can be supported by the foot pedal and the support assembly. If the patient's legs cannot remain upright, the slide plate on the top of the support rod can slide along the slide frame, and the bracket can be extended along the inside of the base to rotate the storage plate and the extending plate to an inclined state. The foot pedal is also inclined synchronously, so that the patient's legs can be placed at an angle, and the rotating assembly can be rotated along the inclined path for treatment.

[0021] 6. Compared with the prior art, the present invention limits the calf and knee of the patient's lower limbs through the assembly of the support component and the foot pedal, and cooperates with the rotating component to drive the pulse stimulation device to rotate during the lifting process, and performs rotational stimulation treatment around the calf and knee, so that the treatment area is more comprehensive, the patient does not need to frequently change the body position, and the patient's pain is alleviated.

A telescopic rod 35 is fixed to the top of the inner ring of the moving ring 31, and a pulse stimulation device 5 is fixed to the top of the extended end of the telescopic rod 35. A swivel 22 is rotatably installed inside the foot pedal 2 through a bearing. The moving ring 31 is transmission-connected to the swivel 22. When using the device, the patient's legs are stepped on the foot pedal 2, and the patient's thighs are supported by the support column. The patient's calves and knees are stimulated and treated in a surrounding and lifting manner through the rotating component 3. The device is small in size, easy to carry and use, and is relatively easy to use. A controller for controlling the pulse device is installed inside the base 1, and the pulse stimulation device 5 is connected to it through wires.

[0033] In this embodiment, the support assembly 4 also includes a sliding frame 43, two sliding frames 43 are symmetrically fixed on the outer surface of the storage plate 41, and a slide plate 44 is slidably connected inside the sliding frame 43, and the outer surface of the slide plate 44 is rotatably connected to the support rod 45 through a rotating shaft, and a plug-in rack 47 is fixed to the bottom of the support rod 45, and the plug-in rack 47 is slidably inserted into the base 1, and a sponge pad 48 is fixed to the top of the extension plate 42, and a locking bolt 49 is threadedly inserted on the outer surface of the storage plate 41, and the inner side of the locking bolt 49 is in compression contact with the extension plate 42, and the extension plate 42 can be pulled out along the inside of the storage plate 41 and tightened by the locking bolt 49 limits the length, and the sponge pad 48 on the top of the extension plate 42 contacts the bottom of the patient's thigh at the rear end of the knee to support the patient's legs. In this process, if the patient can meet the treatment method of upright calf, the legs can be supported by the foot pedal 2 and the support component 4. If the patient's legs cannot remain upright, the slide plate 44 on the top of the support rod 45 slides along the slide frame 43, and the bracket 47 extends from the inside of the base 1, and the storage plate 41 and the extension plate 42 are rotated to an inclined state, and the foot pedal 2 is synchronously tilted, so that the patient's legs can be placed at an angle, and the rotating component 3 can be rotated along the inclined path for treatment.

[0034] In this embodiment, the rotating assembly 3 also includes a winding seat 34, and the winding seat 34 is equidistantly fixed at the bottom of the moving ring 31, and the winding seat 34 is rotated and wound with a steel wire 32 through a winding shaft and a torsion spring. The bottom of the steel wire 32 is fixedly connected to the rotating ring 22 inside the foot pedal 2. A driving motor 21 is fixed at the center of the bottom circle of the foot pedal 2, and the output end of the driving motor 21 is fixedly connected to the rotating ring 22. When the driving motor 21 drives the rotating ring 22 inside the foot pedal 2 to rotate, the moving ring 31 is driven to rotate synchronously through the connection of the steel wire 32, and the moving ring 31 is The limit frame 33 is slidably connected. When the limit frame 33 moves in the vertical direction, it will pull the movable ring 31 to move upward. At this time, the winding seat 34 unwinds the steel wire 32. Because the steel wire 32 has a certain hardness, when the rotating ring 22 rotates, it can drive the movable ring 31 to rotate synchronously through the cooperation of multiple groups of steel wires 32, so as to realize the pulse stimulation device 5 to perform lifting and surrounding stimulation treatment around the calf. Because the patient's foot is on the foot pedal 2 and the calf is located inside the movable ring 31, the movement of the movable ring 31 and the unwinding of the steel wire 32 will not be restricted by the patient's legs.

[0035] In this embodiment, a ball 36 is fixed to the extended end of the telescopic rod 35, and the ball 36 is located at the front end of the pulse stimulation device 5. A first spring 37 is sleeved on the surface of the extended end of the telescopic rod 35, and the other end of the first spring 37 is fixedly connected to the storage end of the telescopic rod 35. The position of the ball 36 will contact the patient's calf skin. Through the elastic force of the first spring 37 on the telescopic rod 35, the pulse stimulation device 5 is always kept at a certain distance from the patient's skin, thereby ensuring the stimulation treatment effect.

[0036] In this embodiment, a driving wheel 38 is rotatably mounted on the inner top surface of the extending plate 42 through a bearing, and a driving motor is mounted inside the driving wheel 38 of the extending plate 42, a driven wheel 39 is rotatably mounted on the inner surface of the bottom of the receiving plate 41 through a bearing, two transmission wheels 310 are symmetrically mounted on the inner surface of the top of the receiving plate 41, and a belt 311 is sleeved on the outer sides of the transmission wheels 310, the driving wheel 38 and the driven wheel 39, a slide groove 312 is opened on the inner surface of the receiving plate 41 at positions corresponding to the two transmission wheels 310, and a slider 313 is slidably connected inside the slide groove 312, the transmission wheel 310 is rotatably mounted on the slider 313, and the slide groove 3 A second spring 314 is fixed between 12 and the slider 313, and limiting rods 315 are fixed on the outer surface of the slider 313 corresponding to the belt 311 passing through the two sides of the transmission wheel 310, and the belt 311 slides through the transmission belt and the limiting rod 315. The limiting frame 33 on one side of the storage plate 41 is rotatably connected to the outer surface of the belt 311 through a transverse rotating shaft, and the limiting frame 33 on the other side of the storage plate 41 is slidably connected to the outer surface of the other side of the belt 311 through a rotating seat. A driving motor is installed inside the extension plate 42 to drive the driving wheel 38 to rotate, and because the belt 311 surrounds the driving wheel 38, the driven wheel 39 and the transmission wheel 310, the belt 311 is allowed to move in a cycle. The two transmission wheels 310 will slide along the slide groove 312 as the height of the extension plate 42 changes, thereby maintaining the tightness of the belt 311. At the same time, the limiting rod 315 on the slider 313 limits the insertion position and the exit position of the belt 311, so that the wrapping range of the belt 311 on the transmission wheel 310 is greater than one hundred and eighty degrees to ensure sufficient friction. When the extension plate 42 slides and adjusts along the inside of the storage plate 41, the slider 313 slides along the slide groove 312 through the elastic force of the second spring 314, and the position of the two transmission wheels 310 changes to maintain the tightness of the belt 311. One side of the limiting frame 33 connected to the belt 311 is fixedly connected, and the other side is slidably connected. It can be simply understood that the limit frame 33 can move in the vertical direction together with the belt 311. Although the moving trajectory of the belt 311 will tilt when it bypasses the transmission wheel 310 during this process, it moves in the vertical direction as a whole. During this process, the limit frame 33 fixedly connected to the belt 311 can slide along the inner surface of the storage plate 41 through the rotation of the shaft, and maintain the same curvature as the inner surface of the storage plate 41, maintaining the clamping effect on the moving ring 31. The limit frame 33 on the other side is directly connected to the belt 311 through the shaft seat, and moves up and down synchronously with the moving ring 31. It can also rotate and move horizontally at a certain angle like the limit frame 33 on the other side.

[0037] When using the device, the patient's legs are placed on the foot pedal 2, the extension plate 42 can be pulled out along the inside of the storage plate 41, and the length is limited by the locking bolt 49, and the sponge pad 48 on the top of the extension plate 42 contacts the bottom of the thigh at the rear end of the patient's knee to support the patient's legs. In this process, if the patient can meet the treatment method of upright calf, the legs can be supported by the foot pedal 2 and the support component 4. If the patient's legs cannot remain upright, the slide plate 44 on the top of the support rod 45 slides along the slide frame 43, and the bracket 47 extends from the inside of the base 1, and the storage plate 41 and the extension plate 42 are rotated to an inclined state, and the foot pedal 2 is synchronously tilted, so that the patient's legs can be placed at an angle, and the rotating component 3 can be tilted along the inclined During the treatment, the driving motor 21 drives the rotating ring 22 inside the foot pedal 2 to rotate, and the connection of the steel wire 32 drives the moving ring 31 to rotate synchronously. The moving ring 31 is slidably connected to the limit frame 33. When the limit frame 33 moves in the vertical direction, it will pull the moving ring 31 to move upward. At this time, the winding seat 34 unwinds the steel wire 32. Because the steel wire 32 has a certain hardness, the rotating ring 22 can drive the moving ring 31 to rotate synchronously through the cooperation of multiple groups of steel wires 32 when rotating, so as to realize the lifting and surrounding stimulation treatment of the pulse stimulation device 5 around the calf. The position of the ball 36 will contact the patient's calf skin, and the elastic force of the first spring 37 on the telescopic rod 35 will keep the pulse stimulation device 5 always in contact with the patient's skin. A certain distance is maintained to ensure the stimulation and treatment effect. The two transmission wheels 310 will slide along the slide groove 312 following the change in the height of the extension plate 42 to maintain the tightness of the belt 311. At the same time, the limiting rod 315 on the slider 313 limits the insertion position and the exit position of the belt 311, so that the wrapping range of the belt 311 on the transmission wheel 310 is greater than one hundred and eighty degrees to ensure sufficient friction. When the extension plate 42 slides and adjusts along the inside of the storage plate 41, the slider 313 slides along the slide groove 312 through the elastic force of the second spring 314, and the position of the two transmission wheels 310 changes to maintain the tightness of the belt 311. One side of the limiting frame 33 connected to the belt 311 is fixedly connected, and the other side is slidably connected. The fixedly connected side can be simply It is understood that the limit frame 33 can move in the vertical direction together with the belt 311. Although the moving trajectory of the belt 311 will tilt when it passes around the transmission wheel 310 during this process, it moves in the vertical direction as a whole. During this process, the limit frame 33 fixedly connected to the belt 311 can slide along the inner surface of the storage plate 41 through the rotation of the shaft, and maintain the same curvature as the inner surface of the storage plate 41, maintaining the clamping effect on the moving ring 31. The limit frame 33 on the other side is directly slidably connected to the belt 311 through the shaft seat, and moves up and down synchronously with the moving ring 31. It can also rotate and move horizontally at a certain angle like the limit frame 33 on the other side. The device is small in size, easy to carry and use, and relatively easy to use.
