Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a lower limb rehabilitation trainer. Background Art
[0002] Diseases of the nervous system, muscle and joint diseases, bone diseases, etc. may all cause the patient's lower limbs to be unable to walk normally. For lower limb dysfunction caused by diseases, surgeries, traumas, etc., rehabilitation training can restore muscle strength, joint flexibility and balance ability, improve gait and walking function. By enhancing the lower limb function, patients can better perform daily activities such as standing and walking, thereby improving the quality of life. For patients who are bedridden and sedentary for a long time, rehabilitation training can prevent complications such as muscle atrophy, pressure sores, and deep vein thrombosis. For middle-aged and elderly people, lower limb rehabilitation training can delay the aging of lower limb muscles and bones and maintain the vitality and function of the lower limbs. Therefore, lower limb rehabilitation training is crucial for restoring lower limb function and improving the quality of life. When using a lower limb rehabilitation trainer, it provides a certain supporting force to the upper body of the patient, reduces the load on the patient's lower limbs, and enables the patient to walk under the support of the trainer. The problems existing in the existing lower limb rehabilitation trainers are as follows: the supporting force provided by the lower limb rehabilitation trainer to the upper body of the patient is fixed, while during the rehabilitation process of the patient, the load on the lower limbs needs to be gradually increased to achieve a better training effect, that is, during the process of the patient's lower limb strength gradually recovering, the role of the lower limb rehabilitation trainer gradually decreases. Now, a lower limb rehabilitation trainer is adopted, and the patient can adjust the magnitude of the supporting force according to his own body weight and rehabilitation degree, adjust the lower limb load, and gradually recover the lower limb function step by step to achieve a better training effect.

[0012] The beneficial effects of the present invention are: (1)Pre-store sufficient air in the trachea so that the height of the support pad matches the height of the patient. When the patient uses it, the support pad can support the upper body of the patient. If the patient needs a greater supporting force, rotate the nut to move the nut away from the trachea, stretch the tension spring, the tension of the tension spring increases, and the pressure relief pressure of the pressure relief valve increases. During the movement of the patient, the inflation component continuously inflates the trachea, and the patient receives a constant supporting force. If the supporting force required by the patient decreases, reverse the nut to reduce the pressure relief pressure of the pressure relief valve. Using the lower limb rehabilitation trainer with the above structure can adjust the lower limb load according to the patient's personal weight, rehabilitation condition, etc., step by step, and gradually restore the lower limb function, which is beneficial to the patient's rehabilitation.
[0013] (2)When the patient uses the trainer, tie the legs to the left training mechanism and the right training mechanism. The left training mechanism and the right training mechanism give certain restrictions and supports to the patient's legs. When the patient moves independently, it drives the left training mechanism and the right training mechanism to operate together. The first rotating shaft and the second rotating shaft rotate. The first rotating shaft drives the first eccentric circular plate to rotate. During the rotation of the first eccentric circular plate, the air entering from the air inlet is pushed into the ventilation hose, so as to continuously inflate the trachea and maintain the stability of the patient's upper limb supporting force.
[0014] (3)The setting of the spring allows relative movement between the shoe and the trapezoidal plate. When the patient lifts the foot, the spring can provide a supporting force to help the patient lift the lower leg. When the patient wants to put the foot down, the spring provides a buffering force, making the patient more comfortable during walking. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.
[0023] Referring to Figures 1-6 as shown, a lower limb rehabilitation trainer according to the present invention includes a frame body 1, a universal wheel 2 provided on the frame body 1, a balance wheel 3 provided on the frame body 1, a training device 4 provided on the frame body 1, and a load reduction device 5 provided on the frame body 1. The load reduction device 5 includes a left load reduction mechanism 51 fixedly provided on the frame body 1, a right load reduction mechanism 52 fixedly provided on the frame body 1, and a restraint belt 532 with both ends fixedly provided on the left load reduction mechanism 51 and the right load reduction mechanism 52 respectively; the right load reduction mechanism 52 includes a support plate 54 fixedly provided on the frame body 1, an air pipe 55 fixedly provided on the support plate 54, a support rod 56 movably provided in the air pipe 55, a support pad 57 fixedly provided on the support rod 56, a pressure relief valve 58 fixedly provided on the air pipe 55, and an inflation assembly 59 provided on the frame body 1 and inflating into the air pipe 55; the left load reduction mechanism 51 has the same structure as the right load reduction mechanism 52.
[0024] Specifically, the pressure relief valve 58 includes a threaded pipe 581 fixedly provided on the air pipe 55, a pull plate 582 fixedly provided at one end of the threaded pipe 581, a nut 583 rotatably provided on the threaded pipe 581, a sealing cylinder 584 movably provided on the nut 583, and a tension spring 585 with two ends fixedly provided on the pull plate 582 and the sealing cylinder 584 respectively.
[0025] Enough air is pre-stored in the air pipe 55 to make the height of the support pad 57 match the height of the patient. When the patient uses it, the support pad 57 can support the upper body of the patient. If the patient needs a greater supporting force, rotate the nut 583 to make the nut 583 away from the air pipe 55, stretch the tension spring 585, the pulling force of the tension spring 585 increases, and the pressure relief pressure of the pressure relief valve 58 increases. During the movement of the patient, the inflation assembly 59 continuously inflates the air pipe 55. When the pressure is greater than the pulling force of the tension spring 585, the gas pushes the sealing cylinder 584 to move outwards, and the gas escapes. In this way, a constant supporting force can be ensured for the patient during walking. If the supporting force required by the patient decreases, rotate the nut 583 in the reverse direction to reduce the pressure relief pressure of the pressure relief valve 58. Using the lower limb rehabilitation trainer with the above structure, the lower limb load can be adjusted according to the patient's personal weight, rehabilitation condition, etc., step by step, and the lower limb function can be gradually restored, which is beneficial to the patient's rehabilitation.

[0028] When a patient uses this trainer, the legs are strapped to the left training mechanism 41 and the right training mechanism 42. The left training mechanism 41 and the right training mechanism 42 give certain restrictions and supports to the patient's legs. When the patient moves independently, the left training mechanism 41 and the right training mechanism 42 are driven to operate together. The first rotating shaft 591 and the second rotating shaft 421 rotate. The first rotating shaft 591 drives the first eccentric circular plate 592 to rotate. During the rotation of the first eccentric circular plate 592, the air entering from the air inlet 599 is pushed into the ventilation hose 598, so as to continuously inflate the trachea 55 and maintain the stability of the patient's upper limb support force.
[0029] Specifically, the right training mechanism 42 further includes a chute 433 provided on the trapezoidal plate 427, a slider 434 movably provided on the chute 433, and a spring 435 with both ends respectively fixed on the chute 433 and the slider 434.
[0030] Specifically, one end of the shoe 429 is rotatably provided on the slider 434.
[0031] The setting of the spring 435 enables relative movement between the shoe 429 and the trapezoidal plate 427. When the patient raises the foot, the spring 435 can provide a supporting force to help the patient lift the calf. When the patient wants to put the foot down, the spring 435 provides a buffering force, making the patient more comfortable during walking.
[0032] Specifically, a guide rod 6 is provided on the frame 1.
[0033] The frame body 1 is provided with a guide rod 6, which plays a certain guiding role for the support pad 57, enabling the support pad 57 to move in the vertical and horizontal directions.

[0035] In addition to the support provided by the support pad 57 to the patient, the restraint band 532 is wrapped around the patient's waist. One end of the elastic band 531 is fixed to the support rod 56, and the elastic band 531 drives the restraint band 532 upward to provide support to the patient from the waist, further reducing the lower limb load of the patient and helping the patient better perform rehabilitation training.
