Description

Technical Field

[0001] The present invention relates to the technical field of joint exercise equipment, and particularly relates to an orthopedic joint exercise device. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. After orthopedic surgery, it is usually necessary to perform rehabilitation exercises on the joint part to accelerate the restoration of the normal function of the joint.

[0003] Currently, for the rehabilitation of the joint part, it is usually necessary for medical staff to help the patient up and place the patient between two armrests, and then manually assist in the exercise rehabilitation. When this traditional rehabilitation exercise takes too long, it will inevitably cause fatigue of the medical staff. Therefore, there is currently a rehabilitation device for joints that can be used by the patient himself. This kind of rehabilitation device still relies on the patient to use a sitting or standing posture to carry out. When the patient is unable to sit or stand, he cannot complete the self-operation. And most of the devices that can complete self-rehabilitation in a lying position are for the patient's knee joint, with relatively single functions and unable to exercise the patient's finger joints, elbow joints and ankle joints.

[0004] In order to solve the above problems, a device is proposed that can allow the patient to maintain a lying position and can simultaneously complete the rehabilitation exercises for the knee joint, finger joints, elbow joints and ankle joints at the same time. Summary of the Invention

[0019] Refer to Figures 1 to 9 , an orthopedic joint exercise device, comprising a fixed base 1, a rotating base 2, a support rod 3, a first horizontal mounting plate 4, a second horizontal mounting plate 5, a T-shaped support rod 18, a support roller 13, a foot fixator 30, a handrail 9, an L-shaped movable plate 14, a driving mechanism, a flipping mechanism, a sliding mechanism, a rotating mechanism, and a finger joint exercise component; The upper end of the fixed base 1 is rotatably installed with a rotating base 2. The upper end of the rotating base 2 is fixedly installed with the cross bar of the T-shaped support rod 18 through a support rod 3. The upper end of the vertical rod of the T-shaped support rod 18 is fixedly installed with a first horizontal mounting plate 4. The fixed base 1 provides a rotating space for the rotating base 2, which is convenient for the doctor to rotate the first horizontal mounting plate 4 to change the angle of the patient and facilitate the nursing operation; The second horizontal mounting plate 5 is fixedly installed on the rear wall of the first horizontal mounting plate 4. The first horizontal mounting plate 4 and the second horizontal mounting plate 5 are an integral body; On both sides of the second horizontal mounting plate 5, armrests 9 are respectively movably installed. Both armrests 9 are driven to rotate by a driving mechanism; On both sides of the upper end of the first horizontal mounting plate 4, support rollers 13 for supporting the thighs of the patient are respectively movably installed. Both support rollers 13 are driven to flip by a flipping mechanism. The two armrests 9 respectively drive the flipping mechanism to work through rotation. The user can drive the two flipping mechanisms to flip the two support rollers 13 by holding the armrests 9 on both sides with both hands. The two support rollers 13 can lift the user's legs by flipping, and the user can bend the knees to exercise the knees; On the front sides of the two support rollers 13, L-shaped movable plates 14 are respectively movably installed. The horizontal plates of the two L-shaped movable plates 14 are respectively movably installed on the upper end of the first horizontal mounting plate 4; The two L-shaped movable plates 14 are respectively driven to slide by a sliding mechanism; The sliding mechanism is driven to work by the flipping mechanism; On the inner sides of the vertical plates of the two L-shaped movable plates 14, foot fixators 30 are respectively rotatably installed. The two foot fixators 30 are respectively movably installed above the horizontal plates of the L-shaped movable plates 14 close to them. The two foot fixators 30 are used to fix the feet of the patient. With the work of the following rotating mechanism, the two foot fixators 30 start to drive the feet of the user to rotate. While the user's knees are being exercised, the ankle joints can also be exercised; The two foot fixators 30 are respectively driven to rotate by a rotating mechanism; The two L-shaped movable plates 14 are respectively driven to work by the sliding driving rotating mechanism; Finger joint exercise components are respectively installed on the inner walls of the two armrests 9. The user can only operate the finger joint exercise components to use the device to exercise other joints, and the finger joint exercise components can also be used as the limiting mechanism of this device to facilitate the user's immediate operation of the device.

[0020] The driving mechanism includes an L-shaped rotating rod 8, a first vertical mounting plate 6, a main shaft, a first spur gear 28, a first rack plate 27, a first guide rod 1801, and a first return spring 29; At the lower ends of the two side walls of the second horizontal mounting plate 5, first vertical mounting plates 6 are respectively and vertically mounted, and the same main shaft is rotatably penetrated and mounted on the two first vertical mounting plates 6; At the two ends of the main shaft, L-shaped rotating rods 8 are respectively and fixedly mounted. At the intersection of the horizontal plate and the vertical plate of the two L-shaped rotating rods 8, they are fixedly connected to the two ends of the main shaft. The two L-shaped rotating rods 8 are respectively movably mounted on the outer walls of the two first vertical mounting plates 6; Two armrests 9 are respectively and fixedly mounted on the upper ends of the horizontal plates of the L-shaped rotating rods 8 close to them; A first straight gear 28 is fixedly sleeved on the middle end of the main shaft; On the rear wall of the vertical rod of the T-shaped support rod 18, a first guide rod 1801 is fixedly mounted. On the upper end of the cross rod of the T-shaped support rod 18 located at the rear side, a first rack plate 27 is slidably mounted, and the first rack plate 27 is slidably penetrated between the first guide rod 1801; The first straight gear 28 and the first rack plate 27 are meshed; A first return spring 29 is sleeved on the outer wall of the first guide rod 27; The first return spring 29 is mounted between the vertical rod of the T-shaped support rod 18 and the first rack plate 27; The two L-shaped rotating rods 8 respectively work through a rotation driving and flipping mechanism. The user can respectively drive the two L-shaped rotating rods 8 to start rotating by holding the armrests 9 on both sides. The two L-shaped rotating rods 8 can drive the main shaft to start rotating through rotation. The main shaft can drive the first straight gear 28 fixedly sleeved on it to start rotating through rotation. The first straight gear 28 can drive the first rack plate 27 meshed with it to start sliding through rotation. Refer to Figure 8 , when the user operates the two armrests 9 to rotate upward, the first rack plate 27 slides backward. As the first rack plate 27 slides backward, the first return spring 29 starts to be compressed. When the user stops rotating the armrests 9, the first return spring 29 starts to reset, and the armrests 9 and the L-shaped rotating rods 8 on both sides will reset to the initial state. During the rotation of the two L-shaped rotating rods 8, they can simultaneously start to drive the subsequent flipping mechanism. Since the user's elbows will naturally bend when operating the armrests 9 on both sides to rotate, this process can exercise the patient's elbow joints.

[0021] The flipping mechanism includes a second vertical mounting plate 7, a first rectangular slider 19, a first connecting rod 11, a second connecting rod 12, and a third connecting rod 10; At the lower ends of the two side walls of the first horizontal mounting plate 4, second vertical mounting plates 7 are respectively and vertically mounted. First rectangular through grooves 701 are respectively provided in the two second vertical mounting plates 7. First rectangular sliders 19 are respectively slidably mounted in the two first rectangular through grooves 701. First connecting shafts are respectively fixedly mounted on the outer walls of the two first rectangular sliders 19; The first ends of the first link 11 are respectively rotatably sleeved on the outer walls of the two first connecting shafts; The second ends of the two first links 11 are respectively rotatably connected to the lower ends of the vertical rods of the L-shaped rotating rods 8 close to them; The upper parts of the middle ends of the two first links 11 are respectively fixedly provided with first connection frames, and the first ends of the second links 12 are respectively rotatably installed in the two first connection frames; Second connection shafts are respectively fixedly installed on the outer walls of the two second vertical mounting plates 7, and the two second connection shafts are respectively installed above the first rectangular through grooves 701 close to them; The first ends of the third links 10 are respectively rotatably sleeved on the outer walls of the two second connection shafts; The two support rollers 13 are respectively rotatably installed on the inner walls of the second ends of the third links 10 close to them; The lower parts of the middle ends of the two third links 10 are respectively fixedly provided with second connection frames, and the second ends of the two second links 12 are respectively rotatably installed in the second connection frames close to them; The two third links 10 respectively drive the sliding mechanism to work through rotation. Refer to Figure 4 , when the patient operates the armrests 9 on both sides to drive the two L-shaped rotating rods 8 to start rotating, the first links 11 on both sides will be respectively driven to deflect. When the first links 11 on both sides deflect upward, the two first rectangular sliders 19 will be respectively driven to slide forward along the two first rectangular through grooves 701. The sliding of the two first rectangular sliders 19 limits the upward deflection trajectories of the two first links 11. As the two first links 11 deflect upward, the two second links 12 will be respectively driven to deflect upward. During the upward deflection of the two second links 12, the third links 10 on both sides will be respectively driven to rotate upward. Since the rotation trajectories of the two third links 10 are fixed, the deflection trajectories of the two second links 12 are also fixed accordingly. The two third links 10 can respectively drive the support rollers 13 on both sides to start rotating upward by rotating upward. While the support rollers 13 support the patient's legs to slowly lift, they will also start to roll because they are in contact with the lower sides of the patient's thighs, which plays a role in relaxing the muscles and increasing the comfort. And during the rotation of the two third links 10, they can also drive the sliding mechanism described later to start working at the same time. Since when the patient's thighs on both sides are supported, the knees are bent and the feet will naturally move backward, this process can exercise the patient's knees. During the whole process, the sliding directions of the first rectangular slider 19 and the L-shaped movable plate 14 are always opposite.

[0022] The sliding mechanism includes a second rectangular slider 1401 and a fourth link 17; The first ends of the fourth links 17 are respectively rotatably installed on the outer walls of the second ends of the two third links 10; On both sides of the upper end of the first horizontal mounting plate 4, second rectangular through grooves 401 are respectively provided; Second rectangular sliders 1401 are respectively and slidably mounted in the two second rectangular through grooves 401, and the upper ends of the two second rectangular sliders 1401 respectively slide through the second rectangular through grooves 401 close to them and are fixedly connected to the bottom of the horizontal plates of the L-shaped movable plates 14; Third connecting shafts are rotatably penetrated and mounted on the vertical plates of the two L-shaped movable plates 14; The second ends of the two fourth connecting rods 17 are respectively rotatably sleeved on the outer walls of the third connecting shafts close to them; The two L-shaped movable plates 14 respectively drive the third connecting shafts close to them to rotate through sliding. Refer to Figure 4 , when the two third connecting rods 10 rotate upward, they will respectively drive the fourth connecting rods 17 on both sides to start deflecting upward. At this time, the first rectangular sliders 19 on both sides start to slide forward. During the upward deflection process of the fourth connecting rods 17 on both sides, they will respectively pull the L-shaped movable plates 14 on both sides to start sliding backward. On the contrary, when the two third connecting rods 10 rotate downward, the first rectangular sliders 19 on both sides slide backward, and the L-shaped movable plates 14 on both sides slide forward. Since the sliding tracks of the two second rectangular sliders 1401 fixedly connected to the two L-shaped movable plates 14 are limited within the second rectangular through grooves 401 that cooperate with them, the sliding tracks of the two L-shaped movable plates 14 are determined. And during the forward and backward sliding process of the two L-shaped movable plates 14, they can drive the foot fixator 30 to slide synchronously. And the foot fixator 30 will start to rotate through the rotation mechanism described later during the sliding process, playing a role in exercising the foot joints of the user.

[0023] The rotation mechanism includes a second spur gear 15 and a second rack plate 16; Second spur gears 15 are respectively fixedly sleeved on the outer walls of the two third connecting shafts, and the two second spur gears 15 are respectively installed between the vertical plates of the L-shaped movable plates 14 and the fourth connecting rods 17 close to them; Second rack plates 16 are respectively fixedly installed on the outer sides of the left and right side walls of the first horizontal mounting plate 4; The two second spur gears 15 are respectively meshed with the second rack plates 16 close to them; The other ends of the two third connecting shafts respectively rotate through the L-shaped movable plates 14 close to them and are fixedly connected between the foot fixators 30 close to them. Refer to Figure 1, during the forward and backward sliding of the two L-shaped movable plates 14, they will respectively drive the two second spur gears 15 to slide synchronously forward and backward. Since the two second spur gears 15 are always in meshing with the two fixed second rack plates 16, the two second spur gears 15 will also start to rotate reciprocally during the forward and backward sliding. During the reciprocal rotation of the two second spur gears 15, they can respectively drive the foot fixators 30 coaxially installed with them to start rotating reciprocally. The foot fixators 30 can drive the user's feet to start rotating reciprocally up and down through the reciprocal rotation, and the user's feet can exercise the ankle joints during the driven rotation. When the patient's legs are supported by the support rollers 13 and lifted upward, at this time, the two L-shaped movable plates 14 will drive the foot fixators 30 to slide backward, and the foot fixators 30 will also start to flip upward while sliding backward to drive the patient's ankles to rotate, realizing multi-directional exercise. When the patient's legs gradually lower along with the support rollers 13, the two L-shaped movable plates 14 start to slide forward, and the two foot fixators 30 also start to rotate downward.

[0024] The finger joint exercise assembly includes movable armrests 20, second guide rods 21, second return springs 22, transmission slide rods 23, movable slide rods 25, L-shaped slide rods 26, limit sleeves 2601, limit posts 801, and fifth connecting rods 24; Two second guide rods 21 are respectively slidably penetrated and installed on the inner walls of the two armrests 9, and the inner ends of the two second guide rods 21 on the same side are respectively fixedly installed with the same movable armrest 20; Second return springs 22 are respectively sleeved on the outer walls of the four second guide rods 21, and the two second return springs 22 on the same side are respectively installed between the movable armrest 20 and the armrest 9 close to them; Blocking disks are respectively installed at the outer ends of the four second guide rods 21, and the four blocking disks are respectively in detachable contact with the outer walls of the armrests 9 close to them; The first ends of the two fifth connecting rods 24 are respectively rotatably installed at the lower ends of the two movable armrests 20, and the second ends of the two fifth connecting rods 24 are respectively rotatably installed with transmission slide rods 23; Third rectangular through grooves 501 are respectively provided on both sides of the upper end of the second horizontal mounting plate 5, and movable slide rods 25 are respectively slidably penetrated and installed in the two third rectangular through grooves 501; Guide rails 2501 are respectively installed at the upper ends of the inner walls of the two movable slide rods 25, and the two transmission slide rods 23 are respectively slidably installed in the guide rails 2501 close to them; Rectangular through holes 601 are respectively provided on the two first vertical mounting plates 6, and the vertical rods of the two L-shaped slide rods 26 are respectively slidably penetrated and installed in the rectangular through holes 601, and the vertical rods of the two L-shaped slide rods 26 are respectively movably installed outside the main shaft; The lower ends of the two movable sliding rods 25 are respectively fixedly connected to the upper ends of the vertical rods of the L-shaped sliding rods 26 close to them, and the two movable sliding rods 25 are respectively movably installed inside the first vertical mounting plate 6 close to them; Limit sleeves 2601 are respectively fixedly installed on the inner walls of the ends of the cross plates of the two L-shaped sliding rods 26; Limit posts 801 are respectively fixedly installed on the outer walls of the intersections of the cross bars and the vertical bars of the two L-shaped rotating rods 8; The two limit sleeves 2601 are respectively in detachable contact with the limit posts 801 close to them. Refer to Figure 5 , when the user holds the armrests 9 on both sides, they need to pinch the movable armrests 20 close to them and start sliding outwards. Since when the movable armrests 20 are not driven, the movable armrests slide inwards under the reset of the second return spring 22. When pinching the movable armrests 20, the patient's finger joints need to overcome the reset force of the second return spring 22, so it will play a certain role in exercising the patient's finger joints. When the user pinches the movable armrests 20 on both sides, the transmission sliding rods 23 connected to the movable armrests 20 through the fifth connecting rods 24 will also start sliding outwards at this time. When the two transmission sliding rods 23 slide outwards, they will respectively drive the two movable sliding rods 25 to slide outwards along the third rectangular through grooves 501 on both sides. The L-shaped sliding rods 26 fixedly connected to the two movable sliding rods 25 can start sliding outwards at this time. The limit sleeves 2601 fixedly connected to the cross bars of the two L-shaped sliding rods 26 can be disengaged from the limit posts 801 at this time. The limit posts 801 are no longer restricted and can start to drive the two L-shaped rotating rods 8 to rotate. During the rotation process, since the movable armrests 20 on both sides will start to rotate synchronously with the armrests 9, as the movable armrests 20 rotate, they will drive the two fifth connecting rods 24 to deflect and convert this part of the deflection ability into the sliding of the transmission sliding rods 23 in the guide rails 2501. When the patient stops pinching the movable armrests 20 on both sides, since the second return spring 22 starts to reset, the L-shaped sliding rods 26 also start to reset inwards, and during the reset process, the limit sleeves 2601 are brought into contact with the limit posts 801. The inward reset force of the limit sleeves 2601 and the friction force between the limit posts 801 can limit the device.

[0025] Implementation method of the present invention: Place this device on a horizontal plane. The caregiver assists the patient to lie on the overall plane of the first horizontal mounting plate 4 and the second horizontal mounting plate 5, and place the user's thighs on the upper ends of the two support rollers 13; After placing the thighs, the user holds the armrests 9 with both hands and squeezes the movable armrests 20 on both sides. Since the patient needs to overcome the restoring force of the second restoring spring 22, this process can exercise the patient's knuckles. During the process of squeezing the movable armrests 20 on both sides, the limiting sleeves 2601 on both sides are disengaged from the limiting posts 801 close to them respectively. Therefore, the restriction on the rotation of the armrest 9 can be released at this time; After squeezing the movable armrests 20 on both sides, start to rotate the armrest 9 upward. Since the patient's elbows will bend spontaneously during the rotation of the armrest 9, this process can exercise the elbow joints; During the rotation of the armrests 9 on both sides, the L-shaped rotating rods 8 on both sides will be driven to rotate respectively. During the rotation of the L-shaped rotating rods 8 on both sides, the two support rollers 13 on the first horizontal mounting plate 4 will be driven to rotate upward respectively. During the upward rotation of the two support rollers 13, they can support the patient's legs to lift upward. As the patient's legs lift upward, the patient's knee joints bend spontaneously, playing a role in exercising the patient's double knee joints; Reference Figure 4 , as the patient's knees bend, the two L-shaped movable plates 14 start to slide backward. At this time, the foot fixators 30 connected to the two L-shaped movable plates 14 also start to drive the patient's feet to slide backward, and start to turn upward under the drive of the rotating mechanism during the sliding process. At this time, the user's feet can start to turn upward, playing a role in exercising the ankle joints of the feet.

[0026] During the user's exercise, the medical staff can rotate the overall plane composed of the first horizontal mounting plate 4 and the second horizontal mounting plate 5 at any time, which is convenient for observing the patient from multiple angles and providing timely auxiliary guidance to the patient.

[0027] The present invention allows the user to exercise the finger joints, elbow joints, knee joints and ankle joints simultaneously in a lying position. The finger joint exercise component of the present invention also serves as the starting component of the present invention. Only when this part of the component is used will the device be driven to work.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
