Abstract
Description
Technical Field
[0001] This invention relates to the field of rehabilitation equipment technology, specifically to a gait training device for children with cerebral palsy. Background Technology
[0002] When children with cerebral palsy undergo rehabilitation, gait correction training is necessary to help them develop muscles and improve their gait to be closer to that of ordinary people. This not only helps their physical development but also reduces inconvenience in daily life. Currently used gait trainers only focus on walking and do not train walking posture. Furthermore, different children have different levels of development and severity of their condition, so the training methods for each person are also different. In normal walking, arm swing also helps with body balance. Therefore, a gait trainer for children with cerebral palsy is proposed. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by proposing a gait training device for children with cerebral palsy. Based on the child's developmental level and the correct movement trajectory of the knee, a customized walking track is designed to simulate the movement position of the knee and gradually train the child's gait. This allows the child's arms to move alternately in sync with the steps, which helps the child correct their gait.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it includes a tracked walking machine; the tracked walking machine is connected to an external power source;
[0005] Its characteristic is that it further comprises:
[0006] The guide mechanism consists of two parts, which are respectively located above and in front of the tracked walking machine.
[0007] Two knee control mechanisms are provided, each connected to a guide mechanism.
[0008] The auxiliary mechanism is connected to the tracked walking machine;
[0009] Through the above technical solution design, the guiding mechanism simulates the movement position of the knee according to the child's development level and the correct movement trajectory of the knee; the knee control mechanism locates the knee, starts the tracked walking machine, and the guiding mechanism leads the child's knee to move, gradually correcting the movement direction of the child's knee, so that the child's gait can be corrected; the assisting mechanism helps the child swing his arms when walking, so that the child's walking posture is more accurate.
[0010] Preferably, the guiding mechanism comprises:
[0011] The walking track is located above one side of the tracked walking machine and is fixed to the inner wall of the mounting plate, which is fixed to the tracked walking machine.
[0012] The roller is embedded in the travel track; ball bearings are embedded at the contact point between the roller and the travel track; two knee control mechanisms are respectively connected to the roller.
[0013] The rotating rod has an "L" shaped structure and is movably inserted into the roller. The short part of the rotating rod is screwed onto the mounting plate through a bearing.
[0014] Through the above technical solution design, a walking track is customized and installed on the mounting plate according to the child's development level and the correct movement trajectory of the knee. When the child walks, the rotating rod rotates, driving the roller to move, so that the knee control mechanism runs according to the shape of the walking track, gradually correcting the movement direction of the child's knee.
[0015] Preferably, the ball bearings are arranged within the travel track;
[0016] Through the above technical design, the ball bearings are made easier to move than the rollers.
[0017] Preferably, the knee control mechanism comprises:
[0018] A sleeve is fitted onto a roller, and the roller has several threaded holes. A fixing bolt is threaded through the threaded holes of the sleeve and the roller.
[0019] Two connecting half-rings are provided, and they are respectively located opposite each other at the inner end of the sleeve. The outer connecting half-ring is screwed to the sleeve through a shaft and a bearing. Each of the two connecting half-rings is provided with a connecting rope at the front, back, top, and bottom. The connecting rope passes through one end of one connecting half-ring and then passes through the other connecting half-ring.
[0020] The number of the card plates is several, and they are arranged in a ring shape above and below each other and abut against the two connecting half rings;
[0021] The silicone pads are in multiple quantities and are fixed to the inner sides of the upper and lower plates respectively.
[0022] The springs are of several kinds and are fixed in a ring shape on the inner ring wall of two connecting half rings. The other end of the spring is fixed to the silicone pad.
[0023] Based on the above technical solution design, a sleeve and connecting half-ring of appropriate size are selected according to the child's knee. The sleeve is placed on the roller, and the fixing bolt is threaded through the threaded holes of the sleeve and roller to fix the sleeve. The first connecting rope on both sides of the connecting half-ring is untied, and the child's knee is inserted into the connecting half-ring, with the child's knee positioned at the connecting half-ring. When the child walks, the child's knee rests against the silicone pad to prevent knee wear, and the spring allows the knee to have room to move, preventing injury to the child and facilitating gradual gait training.
[0024] Preferably, limit plates are fixed to the front and rear sides of the upper and lower sidewalls of the inner connecting half ring, and the limit plates abut against the outer connecting half ring.
[0025] Through the above technical solution design, the limiting plate prevents the connecting half-ring from being misaligned vertically after connection.
[0026] Preferably, two straps are respectively located below the two connecting half-rings at the front and rear, and the two ends of the straps are connected by Velcro; the upper end of the straps is connected to the connecting half-rings by a second connecting rope.
[0027] With the above technical solution, when the child's knee is in the connecting half-ring, the strap fixes the child's lower leg, making it less likely for the knee to come off the connecting half-ring.
[0028] Preferably, the auxiliary mechanism comprises:
[0029] Two electric telescopic rods are provided, and they are fixed at the front and rear of the left end of the tracked walking machine, respectively. The electric telescopic rods are connected to an external power source. Connecting plates are fixed on the movable ends of the front and rear electric telescopic rods.
[0030] Two inclined blocks are fixed to the left side wall of the connecting plate; the left side wall of the inclined blocks is arranged from right to left from the outside to the inside.
[0031] The second electric telescopic rod consists of two rods, each fixed to the inclined surface of the first inclined block. The second electric telescopic rod is connected to an external power source.
[0032] The second inclined block, there are two of them, and they are fixed on the movable end of the second electric telescopic rod respectively. The right side wall of the second inclined block is set perpendicular to the second electric telescopic rod.
[0033] The grips are two in number and are fixed to the left side wall of the second inclined block; the grips are L-shaped.
[0034] Through the above technical solution design, the height of the connecting plate is adjusted by activating the No. 1 electric telescopic rod according to the child's height, so that the height of the grip rod is consistent with the position of the child's arms when walking. When walking, the child holds the grip rod and alternately operates the No. 2 electric telescopic rod, so that the child's arms move alternately and in sync with the steps, which helps the child correct their gait.
[0035] Preferably, an anti-slip pad is fitted and fixed on the vertical bar of the grip;
[0036] Through the above technical design, the anti-slip mat plays a role in preventing slipping.
