[0031] The present invention proposes a paraplegic walking device, please refer to Figures 1 to 4 The paraplegic walker includes a waist protection component 10, a footrest component 20 and a support component 30.

[0032] Among them, the waist protection component 10 is enclosed to form an annular structure, which is used to be arranged around the patient's waist. The waist protection component 10 may specifically include an annular plate structure, which is arranged around the patient's waist. The width of the annular plate structure in the up and down directions may be larger, so that the patient's waist is supported in a larger area and the supporting effect is better. Of course, the waist protection component 10 can also be formed by splicing multiple plates into an annular structure. In order to avoid discomfort to the patient, some soft parts, such as silicone, rubber, sponge, cloth products, etc., can also be arranged on the inner circumference of the waist protection component 10, so that the patient can achieve soft contact with the waist protection component 10, thereby achieving a buffering and protective effect. In addition, the waist protection component 10 can also be a structure similar to a belt.

[0033] There are usually two foot pedal assemblies 20, which are spaced apart in the left-right direction and are located below the waist support assembly 10. The foot pedal assembly 20 has a footrest 21 for supporting the patient's feet, that is, the left and right feet of the patient are placed on two different footrests 21 respectively. The purpose of spacing the two foot pedal assemblies 20 in the left-right direction is to prevent interference between the two foot pedal assemblies 20 when they move forward in sequence. Some protective structures can also be set on the foot pedal assembly 20, such as straps to tie up the patient's feet to prevent relative movement between the feet and the footrest 21. Alternatively, a limiting groove can be set on the footrest 21, and the sole of the patient's foot is placed in the limiting groove, which can also prevent the patient's foot from moving.

[0034] Similarly, there are two support assemblies 30, and the lower ends of the two support assemblies 30 are connected to the two foot pedals 21, that is, the lower end of one support assembly 30 is connected to one foot pedal 21, and the lower end of the other support assembly 30 is connected to the other foot pedal 21. The upper ends of the two support assemblies 30 are connected to the waist protection assembly 10, so as to support the waist protection assembly 10. In this embodiment, the two support assemblies 30 are also distributed along the left and right directions, and are generally distributed on the left and right sides of the waist protection assembly 10, so as to support the left and right sides of the waist protection assembly 10 and achieve force balance. It can be imagined that the support assembly 30 generally extends along the up and down direction. The support assembly 30 can be a connecting rod structure, or the support assembly 30 is a support plate 211, or the support assembly 30 is formed by a combination of multiple connecting rods, etc.

[0035] In order to realize the forward and backward movement of the foot pedal assembly 20, in one embodiment, the upper end of the support assembly 30 is movably connected to the waist protection assembly 10 so as to be able to swing forward and backward relative to the waist protection assembly 10, thereby driving the foot pedal 21 to swing forward and backward. In specific operation, when the lower end of the left support assembly 30 is swung forward, the left support assembly 30 drives the left foot pedal assembly 20 to move forward, thereby driving the patient's left foot to step forward; then, when the lower end of the right support assembly 30 is swung forward, the right support assembly 30 drives the right foot pedal assembly 20 to move forward, thereby driving the patient's right foot to step forward, and the left and right support assemblies 30 are swung alternately in this way, thereby realizing the patient's upright walking. At the same time, since the patient's waist is surrounded by the waist protection assembly 10, the waist protection assembly 10 protects and supports the patient's waist to prevent the patient from falling. By using the paraplegic walker, it is possible to effectively assist paraplegic patients to walk upright, so that the patients can exercise, reduce or even avoid the occurrence of complications of the patients.

[0036] The paraplegic walker also includes two knee pad assemblies 40, each of which is connected to one of the foot pedals 21, and the knee pad assemblies 40 are used to fix the patient's knees. The knee pad assemblies 40 may have a strap structure to enclose the patient's knees to prevent the knees from swinging and causing the feet to shift relative to the foot pedals 21. In addition, the knee pad assemblies 40 may also adopt an arc-shaped protective plate structure to cover the front side of the knees to prevent them from falling forward. The knee pad assemblies 40 are directly connected to the foot pedals 21, which facilitates the positioning of the knee pad assemblies 40 and the area on the foot pedals 21 for the patient's feet to be placed, thereby better limiting the knees and feet.

[0037] In one embodiment, a rotation hole 1131 is respectively provided on the left and right sides of the waist protection assembly 10, and the support assembly 30 includes a support rod 31, which extends substantially in the up-down direction, and each of the support rods 31 is rotationally matched with one of the rotation holes 1131, and the lower end of the support rod 31 is directly connected to the footrest 21. In this embodiment, there is a gap between the support rod 31 and the hole wall of the rotation hole 1131, so as to prevent the two from locking, so that when the upper end of the support rod 31 is pushed backward, the lower end of the support rod 31 can swing forward.

[0038] In this embodiment, the waist protection assembly 10 has an annular guard plate 11, and a rotation hole 1131 is respectively provided on the left and right sides of the annular guard plate 11, and the support rod 31 is rotatably matched with the rotation hole 1131 on the annular guard plate 11. The shape of the annular guard plate 11 is generally elliptical, which can better fit the patient's waist. In addition, the annular guard plate 11 is usually in close contact with the patient's waist, so that the patient's waist can be clamped to prevent tipping.

[0039] In order to prevent the waist protection assembly 10 from moving up and down, in one embodiment, the support assembly 30 further includes a limiter, which is used to limit the upward and downward movement of the waist protection assembly 10. Specifically, the limiter includes an upper limiter 32 and a lower limiter 33. The upper limiter 32 and the lower limiter 33 are respectively connected to the support rod 31, the upper surface of the annular guard plate 11 abuts against the lower surface of the upper limiter 32, and the lower surface of the annular guard plate 11 abuts against the upper surface of the lower limiter 33.

[0040] In one embodiment, the lower limit member 33 is a sleeve tightly sleeved outside the support rod 31. The sleeve form has the effect of simple structure. In order to achieve the connection between the lower limit member 33 and the support rod 31, the outer diameter of the support rod 31 can be gradually increased from top to bottom. Then, when the sleeve is sleeved downward, the gap between the support rod 31 and the support rod 31 gradually decreases until the two are tightly fitted. In addition, the lower limit member 33 and the support rod 31 can also be integrally formed. In addition, the upper limit member 32 can also be a sleeve sleeved outside the support rod 31. Of course, the lower limit member 33 and the upper limit member 32 can also be structures such as screws, pins, and shoulders.

[0041] In one embodiment, the support rod 31 is a hollow tube, and the upper limit member 32 has a sleeve section 321 and a limit section 322 distributed from bottom to top, the sleeve section 321 is sleeved in the support rod 31, and the outer diameter of the limit section 322 is larger than the outer diameter of the sleeve section 321, and respectively abuts against the upper end surface of the support rod 31 and the upper surface of the annular guard plate 11. In this embodiment, the sleeve section 321 is generally cylindrical or cylindrical, and is tightly matched with the support rod 31 to prevent the sleeve section 321 from detaching from the support rod 31 along the axial direction of the support rod 31. The limit section 322 is generally a shoulder on the sleeve section, and by abutting against the upper end surface of the support rod 31, the entire upper limit member 32 can be limited to move downward.

[0042] Specifically, the annular guard plate 11 includes a waist protection front plate 111, a waist protection back plate 112 and two guard plate connectors 113 which are arranged to form an annular structure. The two guard plate connectors 113 are respectively arranged at the left and right ends of the waist protection front plate 111. The waist protection front plate 111 and the waist protection back plate 112 are respectively detachably connected to the guard plate connectors 113; the guard plate connectors 113 are provided with the rotating holes 1131. By dividing the annular guard plate 11 into a plurality of plate bodies, on the one hand, the processing of the annular guard plate 11 can be facilitated, and each part can be formed separately. On the other hand, when one of the parts is damaged, only the corresponding damaged part needs to be replaced, which is conducive to cost saving. In addition, the waist protection front plate 111 and the waist protection back plate 112 are respectively detachably connected to the guard plate connectors 113, which makes it easy for patients to open the waist protection front plate 111 or the waist protection back plate 112 to facilitate the use of the patients. Specifically, the detachable connection method may include a snap connection, a screw connection, a latch connection, a lock connection, and the like.

[0043] The waist guard front plate 111 and the waist guard rear plate 112 are both substantially extended in the left-right direction, and the lengths of the two sides are relatively long. The guard plate connecting member 113 can be substantially columnar or block-shaped. In one embodiment, the guard plate connecting member 113 has a sleeve, and the hollow area of ​​the sleeve constitutes a rotation hole 1131.

[0044] In one embodiment, one end of the waist protection back plate 112 is rotatably connected to one of the guard plate connecting pieces 113 , and the other end of the waist protection back plate 112 is snap-fitted to another of the guard plate connecting pieces 113 , thereby facilitating the opening of the waist protection back plate 112 .

[0045] In order to achieve better support and limiting effects on the waist, in one embodiment, the inner circumference of the annular guard plate 11 is provided with four waist guard plates 12, and the four waist guard plates 12 are arranged in front, back, left and right of the annular guard plate 11; the height of the waist guard plate 12 in the up and down direction is greater than the height of the annular guard plate 11. The setting of the waist guard plate 12 can increase the contact area with the patient's waist, and can achieve a larger support width in the up and down direction, so as to prevent the patient from tipping over. Optionally, the two waist guard plates 12 on the left and right sides are symmetrically arranged with the two waist guard plates 12 on the front and back sides as the center, so as to achieve force balance. In addition, the waist guard plate 12 can be integrally formed with the annular guard plate 11, so that the inner surface of the waist guard plate 12 is flush with the inner circumference of the annular guard plate 11, so that the waist guard plate 12 and the annular guard plate 11 work together to support the patient's waist.

[0046] In one embodiment, the support rod 31 is a telescopic rod, which can adjust the support height, that is, adjust the height of the waist support assembly 10 to accommodate patients of different heights.

[0047] To facilitate the front and back swinging of the support assembly 30, in one embodiment, the paraplegic walker further includes an armrest 34, which is connected to the upper end of the support rod 31 and extends forward. It should be noted that an armrest 34 is provided at the upper end of each support rod 31. The patient can push the armrest 34 to swing the support rod 31 connected to the armrest 34 forward. Optionally, the armrest 34 is provided on the upper limit member 32.

[0048] In one embodiment, the foot pedal assembly 20 further includes a connecting member 22, and the connecting member 22 is rotatably connected to the two foot pedals 21 respectively, so as to be able to swing forward and backward with the foot pedals 21. In this embodiment, the rotation axis of the connecting member 22 and the foot pedal 21 is along the up-down direction. Of course, in other embodiments, the rotation axis between the connecting member 22 and the foot pedal 21 can also be along other directions, as long as the connecting member 22 can be swung forward and backward. Specifically, when the left foot pedal assembly 20 swings forward, the left end of the connecting member 22 is driven to swing forward, and when the right foot pedal assembly 20 swings forward, the right end of the connecting member 22 is driven to swing forward. In this embodiment, the setting of the connecting member 22 can limit the swing amplitude of the left foot pedal assembly 20 relative to the right foot pedal assembly 20, and can also limit the swing amplitude of the right foot pedal assembly 20 relative to the left foot pedal assembly 20, thereby avoiding too large a step and avoiding the swinging of the left foot pedal assembly 20. The purpose of setting the connecting piece 22 is to connect the left and right foot pedals 21 to prevent the two foot pedals 21 from separating. In this way, there is a stride limit when the patient steps forward, which can further prevent the patient from falling.

[0049] In one embodiment, the connecting member 22 is located on the bottom surface of the footrest 21 , which can make the connecting member 22 bear force more evenly than if it is arranged on the side surface.

[0050] Optionally, the footrest 21 includes a support plate 211 and a support frame 212 located on the bottom surface of the support plate 211, and the connecting member 22 is rotatably connected to the support frame 212. The setting of the support frame 212 can strengthen the strength of the support plate 211 and achieve a better supporting effect. The support frame 212 and the footrest 21 can be detachably connected or welded. Optionally, the support frame 212 extends along the periphery of the support plate 211 in a frame shape, so as to achieve a better support and strengthening effect on the support plate 211 along the periphery of the support plate 211.

[0051] The paraplegic walker includes an axle pin, the support frame 212 of the pedal 21 is provided with a first through hole, the connecting member 22 is provided with a second through hole, the axle pin passes through the first through hole and the second through hole, and nuts are respectively provided at both ends of the axle pin to restrict the connecting member 22 and the support frame 212 between the two nuts to prevent the two from being separated. In addition, a rotating shaft can also be directly processed on the support frame 212 or integrally processed on the connecting member 22 to realize the rotational connection between the support frame 212 and the connecting member 22.

[0052] In the above, the connecting member 22 is in the shape of a long strip, and the plate-like structure has a larger support area, which can achieve better connection and limiting effects. Of course, the connecting member 22 can also be in the shape of a column, a triangle or other shapes.

[0053] In one embodiment, the bottom surface of the footrest 21 is provided with a first foot 23. Specifically, the footrest 21 has a first side edge 213 and a second side edge 214 opposite to each other, and the first side edges 213 of the two footrests 21 are located between the two second side edges 214; the bottom surface of the footrest 21 is provided with a first foot 23, and the first foot 23 is close to the first side edge 213. This is equivalent to that when the footrest 21 is in a horizontal state, the first foot 23 is in contact with the ground at a position close to the first side edge 213, and the footrest 21 is suspended from the ground at a position close to the second side edge 214. When walking is required, take the right foot as an example for explanation, the patient's body tilts to the left, and the center of gravity falls on the left side, so that the first side edge 213 and the second side edge 214 of the left footrest 21 are in contact with the ground, and the right footrest 21 is completely suspended. At this time, by pushing the right handrail 34, the right support rod 31 swings forward, thereby driving the right footrest 21 to move forward, and the right footrest 21 is stepped forward. Similarly, to achieve stepping with the left foot, the body is tilted to the right, and the center of gravity falls on the right. Due to the arrangement of the first base 23, the bottom of the footrest 21 is uneven. When the corresponding foot needs to be stepped, the corresponding footrest 21 is suspended in the air, and the footrest 21 can be tilted more flexibly to reduce the resistance of the footrest 21, thereby greatly facilitating the patient's operation.

[0054] In one embodiment, the bottom of the footrest 21 is provided with a plurality of first feet 23, and the plurality of first feet 23 are arranged at intervals along the first side edge 213. The provision of a plurality of first feet 23 can achieve a more balanced support effect in the front-to-back direction and prevent tipping in the front-to-back direction.

[0055] In one embodiment, the bottom surface of the footrest 21 is further provided with a second foot 24, the second foot 24 is close to the second side edge 214, and the height of the second foot 24 is less than the height of the first foot 23. In this way, the footrest 21 is in contact with the ground through the first foot 23 and the second foot 24, and the contact area between the footrest 21 and the ground is small, which can reduce the resistance of the ground, thereby facilitating its forward swing. In addition, by arranging the second foot 24 near the second side edge 214, when the center of gravity of the patient tilts toward the second side edge 214, a part of the second side edge 214, i.e., the second foot 24, contacts the ground, rather than the entire second side edge 214 impacting the ground, which can reduce the impact.

[0056] Optionally, the two corners of the footrest 21 located at the first side edge 213 are each provided with a first foot 23, and the two corners of the footrest 21 located at the second side edge 214 are each provided with a second foot 24. That is, the first foot 23 and the second foot 24 are generally distributed along the circumference of the footrest 21 and are distributed at the four corners of the footrest 21, so as to achieve better support in four different directions of front, back, left, and right. The corner in this embodiment refers to the position where two adjacent sides intersect. In addition, more first feet 23 and second feet 24 can be provided at the bottom of the footrest 21.

[0057] The footrest 21 includes a support plate 211 and a support frame 212 located at the bottom of the support plate 211, and the first foot 23 and the second foot 24 are arranged on the support frame 212. Optionally, the first foot 23 and the second foot 24 are integrally formed with the support frame 212. The support frame 212 can strengthen the strength of the support plate 211 and prevent the support plate 211 from breaking. In addition, the footrest 21 can also be an integral plate body, that is, it does not include the support frame 212, which can also provide a supporting effect on the sole of the foot.

[0058] In one embodiment, a plurality of feet are provided on the bottom surface of the foot pedal 21 at intervals along the circumferential direction. The feet are in contact with the ground, so that the lower plate surface of the foot pedal 21 can be spaced from the ground, thereby reducing the contact area between the foot pedal 21 and the ground, reducing the resistance of the foot pedal 21 to the ground, and allowing the foot pedal 21 to swing more flexibly.

[0059] Specifically, the plurality of feet include a first foot 23 and a second foot 24, wherein the first foot 23 is disposed between two adjacent footboards 21, i.e., close to the first side edge 213, and the second foot 24 is disposed on a side away from the two footboards 21, i.e., close to the second side edge 214; the height of the first foot 23 is greater than the height of the second foot 24. Of course, in other embodiments, the heights of the first foot 23 and the second foot 24 may be the same.

[0060] In order to prevent the patient from tipping over to the left or right side, in one embodiment, the second side edge 214 is provided with an extension section 216, and the extension section 216 extends in a direction away from the first side edge 213. The provision of the extension section 216 is equivalent to increasing the width of the footrest 21 in the left and right directions, so that the support area in the left and right directions is larger. Therefore, even if the center of gravity of the patient tilts to one side, the extension section 216 can ensure that the center of gravity of the patient always falls within the range of the footrest 21, thereby preventing the patient from tipping over.

[0061] Optionally, the second side edge 214 is provided with two extension sections 216 , and the two extension sections 216 are distributed front to back, so that the force in the front to back direction is more balanced.

[0062] In one embodiment, the front extension section 216 extends obliquely forward, and the rear extension section 216 extends obliquely backward. Therefore, the ends of the two extension sections 216 away from the second side edge 214 are staggered in the front-to-back direction. On the one hand, there can be two support points with a large distance in the front-to-back direction, and no matter the patient falls forward or backward, the center of gravity of the patient can be guaranteed to fall between the front and rear extension sections 216; on the other hand, an outward gap is formed between the two extension sections 216, and the gap is gradually expanded, which can save materials.

[0063] Optionally, the angle between the two extension sections 216 is greater than or equal to 90°. Specifically, the angle between each extension section 216 and the left-right direction is greater than or equal to 45°. This allows the two extension sections 216 to have a larger support distance in the front-to-back direction while ensuring that the two foot pedals 21 have a larger support distance in the left-to-right direction.

[0064] In one embodiment, the front side edge 215 of the footrest 21 extends obliquely forward in the direction from the first side edge 213 to the second side edge 214. This is equivalent to that the support distance in the front-to-back direction at the first side edge 213 is narrower, which can save materials. Since the position of the first side edge 213 is to centrally support the patient through the first side edges 213 of the two footrests 21, even if the front-to-back support distance here is small, the patient's tendency to fall can be reduced. At the second side edge 214, the support distance in the front-to-back direction is wider, so when the patient's body tilts, it can be ensured that the patient's center of gravity will not exceed the farthest support point.

[0065] In this embodiment, the front side edge 215 of the footrest 21 constitutes one of the side edges of the front extension section 216. Therefore, the extension section 216 can extend forward while extending sideways, thereby increasing the width of the left and right sides and the front and rear sides.

[0066] In one embodiment, the rear side of the footrest 21 has a clearance gap 217, which can allow a wheelchair to enter and exit, and achieve contact between the wheelchair and the paraplegic walker, thereby facilitating the patient to move from the wheelchair to the paraplegic walker. Optionally, the clearance gap 217 is flared to have a guiding effect.

[0067] Specifically, the clearance gap 217 has a groove bottom 2171 and a first groove wall 2172, the groove bottom 2171 faces the rear side, the first groove wall 2172 is close to the second side edge 214, and the angle between the first groove wall 2172 and the groove bottom 2171 is greater than or equal to 45°. In this way, while ensuring a better supporting effect, the use of the foot pedal 21 is reduced, saving costs.

[0068] The first groove wall 2172 constitutes one of the side edges of the rear extension section 216. Therefore, the extension section 216 can extend toward the side and also toward the rear, thereby increasing the width of the left and right sides and the front and rear sides.

[0069] In one embodiment, the footrest 21 is provided with a sole fixing member 25, and the sole fixing member 25 is detachably connected to the footrest 21, so that the sole fixing member 25 is convenient to remove and replace. Specifically, the sole fixing member 25 has a baffle 251, and the baffle 251 is enclosed to form an annular structure, and the front side of the annular structure has a notch. When the patient's foot is inserted into the annular structure, the foot can be restricted from moving backward and to the left and right sides. The notch on the front side of the annular structure can adapt to different lengths of soles, ensuring that different lengths of soles can be inserted into the annular structure.

[0070] The sole fixing member 25 further includes a bottom plate 252, and the bottom plate 252 is detachably connected to the footrest 21, and the baffle 251 is arranged along the edge of the bottom plate 252. The bottom plate 252 and the footrest 21 can be fixed by screws or buckles.

[0071] In this embodiment, the two sole fixing members 25 are located between the two support components 30 , that is, the support components 30 are arranged at an outer position, the support width is larger, and the balancing effect is better.

[0072] The knee brace assembly 40 includes two support arms 41 and a knee fixing plate 42. The two support arms 41 are connected to the left and right sides of the sole fixing member 25, and the left and right sides of the knee fixing plate 42 are connected to the upper ends of the two support arms 41. By providing two support arms 41, the forces on the left and right sides of the knee fixing plate 42 are more balanced. The support arms 41 are connected to the sole fixing member 25, which can better ensure the relative position between the two and jointly realize the positioning of the sole and the knee. In addition, the knee fixing plate 42 can limit the knee from falling forward. The left and right ends of the knee fixing plate 42 are bent backward so that the knee fixing plate 42 forms a structure open backward. The knee fixing plate 42 can be generally arc-shaped and arranged around the front and left and right sides of the knee to better limit the knee. In other embodiments, the knee brace assembly 40 can also be provided with a strap to bind the knee.

[0073] In order to adjust the height of the knee fixing plate 42, in one embodiment, a plurality of mounting positions 411 are provided on the support arm 41 at intervals in the vertical direction, and the knee fixing plate 42 can be installed at one of the plurality of mounting positions 411. Specifically, the mounting position 411 can be a mounting hole, a mounting protrusion, a slot, etc. By connecting the knee fixing plate 42 to mounting positions 411 of different heights, the height of the knee fixing plate 42 can be adjusted to accommodate patients of different heights.

[0074] The support arm 41 is rotatably connected to the sole fixing member 25 so as to be able to rotate forward and backward relative to the foot pedal 21; a positioning structure 43 is also provided between the support arm 41 and the foot pedal 21, and the positioning structure 43 is used to limit the support arm 41 from continuing to rotate after the support arm 41 rotates forward and backward to the right position. The support arm 41 is rotatably connected to the baffle 251 of the foot pedal assembly 20. Specifically, the positioning structure 43 has a locked state and an unlocked state. In the locked state, the support arm 41 is fixed relative to the sole fixing member 25; in the unlocked state, the support arm 41 can rotate forward and backward relative to the sole fixing member 25. The positioning structure 43 can be a structure such as a hundred-tooth tooth, a positioning pin and a positioning hole, a lifting and pressing lock, etc. For example, the positioning structure 43 can be a structure on the cart that limits the rotation of the wheel. The positioning structure 43 can also include a locking shell, a locking block is provided inside the locking shell, a locking spring is provided between the locking block and the locking shell, and an unlocking handle is provided on the locking block. Since the support arm 41 is rotatably connected to the sole fixing member 25, the front and rear positions of the knee fixing plate 42 on the support arm 41 can be adjusted to meet the usage requirements of different patients.
