Description

Technical Field

[0001] The present invention relates to the technical field of medical machinery, in particular to a multi-gait adjustment training device. Background Art

[0002] Patients with lower limb paralysis due to cerebral palsy, stroke, or other causes require assisted walking training devices during rehabilitation training. Due to their weak lower limbs, they have difficulty standing and walking during walking training. Existing assisted walking training devices are limited in functionality and are only suitable for those with strong upper limb support and good grip function.

[0003] In the prior art, the invention patent with patent publication number CN110123587A is a leg rehabilitation device and a single-leg auxiliary training device, which includes a roller walking part, a foot suspension part installed in the roller walking part, a pressure detection part for detecting the current pressure of the foot suspension part, and a controller connected to the pressure detection part and the roller walking part. During the center of gravity transfer training, the controller controls the roller walking part to stop, facilitating muscle strength training. During walking training, when the center of gravity is transferred to the healthy leg, the controller starts the roller walking part to walk to a preset step length based on the signal sent by the pressure detection part when the current pressure is less than the preset pressure, thereby achieving gait training. When the center of gravity is transferred to the disabled leg, the controller controls the roller walking part to stop based on the signal sent by the pressure detection part, and steps on the foot suspension part to achieve muscle strength training. Although the roller walking part can actively drive the disabled leg to step out, the training device of the prior art can only perform single-leg training. It is suitable for patients with physical conditions that only need to train one leg and the other leg has a certain standing ability. However, the existing technology is not applicable to people who cannot stand normally, or cannot keep the distance between their legs when standing, or who kick their legs or adduct their lower limbs while walking.

[0036] See also Figure 1 and Figure 2 As shown, the present invention provides a multi-gait adjustment training device, including a base 1230, a stepless height adjustment device 400, a weight reduction device 500, and a leg separation device 600. One end of the stepless height adjustment device 400 is connected to the base 1230, and the other end is connected to the weight reduction device 500, so that the weight reduction device 500 and the stepless height adjustment device 400 can be raised and lowered synchronously. The leg separation device 600 is fixedly connected to the base 1230, and the leg separation device 600 guides the gait cycle. The base 1230 assists the leg separation device 600, which can prevent the training device from moving backward and adjust the gait speed.

[0037] The leg-split device 600 includes a longitudinal adjustment device 610, a transverse adjustment device 620, and a leg knee pad 630. The longitudinal adjustment device 610 is fixedly connected to the base 1230, and the transverse adjustment device 620 is perpendicularly connected to the longitudinal adjustment device 610. The transverse adjustment device 620 is height-adjustable on the longitudinal adjustment device 610. The leg knee pad 630 is engaged with the transverse adjustment device 620 and can slide along the direction of the transverse adjustment device 620. The leg knee pad 630 can also be adjusted in height twice in the longitudinal direction.

[0038] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the base 1230 includes a base body 100, a wheel anti-rollback device 200, and a damping adjustment device 300. The base body 100 includes a mounting frame 110 and a connecting rod 120. The two mounting frames 110 are symmetrically arranged, and the ends of the connecting rod 120 are respectively fixed to the two mounting frames 110. Two stepless height adjustment devices 400 are symmetrically arranged and respectively connected to a pair of mounting frames 110. The columns 611 are fixed to the connecting rods 120. Two sets of wheel anti-rollback devices 200 are respectively fixed to the two mounting frames 110; two damping adjustment devices 300 are respectively connected to the wheel anti-rollback devices 200 to increase the damping of the wheel anti-rollback devices 200.

[0039] The wheel anti-rollback device 200 includes a front wheel 210 and a rear wheel anti-rollback device 220 . The front wheel 210 is fixed to the mounting frame 110 via a front wheel fixing plate 211 and is located at one end close to the connecting rod 120 .

[0040] The rear wheel anti-rollback device 220 includes a rear wheel fixing plate 221, a rear wheel 222, an adjustment knob 223, a ratchet 224, a non-return pawl 225, a tension spring 226, and a rotating shaft 227. The rear wheel fixing plate 221 is fixedly connected to the mounting frame 110. The rotating shaft 227 passes through the rear wheel fixing plate 221 and the non-return pawl 225, and then connects to the rear wheel 222. This allows the ratchet 224 and rear wheel 222 to rotate coaxially, with the ratchet 224 abutting the rear wheel fixing plate 221. The non-return pawl 225 is rotationally connected to the rear wheel fixing plate 221 and is located on the same side as the ratchet 224. A fixing rod 2251 is provided on the non-return pawl 225, and an annular groove 2252 is provided on the end of the fixing rod 2251 away from the non-return pawl 225. One end of the tension spring 226 is fixed to the rear wheel fixing plate 221 and is on the same side as the non-return pawl 225. The other end engages with the annular groove 2252. The limiting end of the adjustment knob 223 passes through the rear wheel fixing plate 221 and is located in the rotation path of the non-return pawl 225. Rotating the adjustment knob 223 can engage or disengage the non-return pawl 225 with the ratchet 224.

[0041] The swing arm of the check pawl 225 is arc-shaped, and the adjustment knob 223 is located within the arc of the swing arm. When the adjustment knob 223 is rotated clockwise, the stop end of the adjustment knob 223 protrudes from the rear wheel fixing plate 221. Due to the tension of the tension spring 226, the swing arm of the check pawl 225 presses against the stop end of the adjustment knob 223, and the check pawl 225 and the ratchet 224 separate. When the adjustment knob 223 is rotated counterclockwise, the stop end of the adjustment knob 223 retracts, no longer restraining the check pawl 225. The tension spring 226 quickly pulls the check pawl 225 into the tooth groove of the ratchet 224, causing the ratchet 224 to stop, simultaneously stopping the rotation of the rear wheel 222 and preventing it from moving backward. The wheel anti-rollback device 200 can prevent the training device from moving backward and is suitable for patients who lack good head or trunk control.

[0042] See also Figures 1 to 7 As shown, in one embodiment of the present invention, the damping adjustment device 300 is connected to the rear wheel anti-rollback device 220 and includes a gear knob 310, a cable (not shown), a brake disc 330, and a disc brake device 340. The gear knob 310 is fixedly connected to the mounting frame 110. The brake disc 330 is coaxially connected to the rear wheel 222 and located between the ratchet 224 and the rear wheel 222. The disc brake device 340 is fixed to the rear wheel fixing plate 221, with the brake disc 330 partially located within the disc brake device 340. One end of the cable is fixedly connected to the gear knob 310, and the other end is fixedly connected to the disc brake device 340. Adjusting the gear position of the gear knob 310 adjusts the friction force that pulls the disc brake device 340 to clamp the brake disc 330.

[0043] Specifically, the disc brake assembly 340 includes a first housing 341, a second housing 342, a friction plate assembly 343, a single piston assembly 344, and a fixed guide arm 345. The first housing 341 and the second housing 342 are fixedly connected at one end and open at the other end to form a receiving space 3412, with the opening facing the brake disc 330. The friction plate assembly 343 is located within the receiving space 3412.

[0044] The friction plate assembly 343 includes a brake caliper 3431, a first friction plate 3432, a second friction plate 3433, and a brake link 3434. The brake link 3434 has threads at its base and a smooth shaft at its end. The end of the brake link 3434 passes through the first housing 341 and is threadedly connected thereto. It then passes through the first friction plate 3432, the brake caliper 3431, the second friction plate 3433, and finally connects to the second housing 342. The ends of the brake caliper 3431 are fixedly connected to the first and second friction plates 3432, 3433, respectively. A space 3435 is defined between the first and second friction plates 3432, 3433, and the brake disc 330 is positioned within this space 3435.

[0045] The second housing 342 is fixedly connected to the rear wheel mounting plate 221. A single-piston device 344 and a fixed guide arm 345 are connected to the second housing 342 and located on the same side of the second housing 342. The single-piston device 344 includes a swingarm screw 3441, a ball nut 3442, and an elastic coil 3443. The ball nut 3442 is mounted on the swingarm screw 3441. One end of the elastic coil 3443 is fixedly connected to the ball nut 3442, and the other end is fixedly connected to the second friction plate 3433. The other end of the cable passes through the fixed guide arm 345 and is fixedly connected to the swingarm of the swingarm screw 3441. When the gear knob 310 is adjusted, the swing arm screw 3441 swings toward or away from the fixed guide arm 345. Simultaneously, the ball nut 3442 moves toward the second friction plate 3433, squeezing the space 3435 and causing the first and second friction plates 3432, 3433 to grip the brake disc 330. Alternatively, the ball nut 3442 moves away from the second friction plate 3433, increasing the space 3435 and reducing the friction between the first and second friction plates 3432, 3433, and the brake disc 330. The damping adjustment device 300 can adjust gait speed, helping patients improve their balance, reducing the risk of falls and injuries, and ensuring patient safety.
