Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation assistive equipment, in particular to a walking assistive device for medical rehabilitation. Background Art

[0002] After undergoing surgery, patients are generally not able to move easily and have to lie in bed or use a fixed posture to recover, which is not conducive to blood circulation and recovery. Medical rehabilitation is the use of medical means to diagnose, evaluate and treat patients from a medical perspective to promote the recovery of their physical functions. During the process of medical rehabilitation, many patients, especially those with leg injuries, need to use walking aids for rehabilitation walking training because of inconvenience in walking.

[0003] Most of the existing walking assistance devices are walkers. When in use, the patient holds the handrails to lift the walker, and then tilts the walker to extend the bottom end forward to achieve forward movement. During use, the patient needs to move the walker forward every few steps. When moving the walker, since the walker is off the ground, the user can only stand independently for support without other leverage points. At the same time, the user has to complete additional hand movements to move the walker, which increases the difficulty of the patient standing independently and causes a greater risk of tipping over during the process of moving the walker. In addition, the existing walker lacks safety protection, and the entire walker is prone to tipping over, causing secondary injuries to the patient. Summary of the invention

[0016] 2. The present invention provides a walking assist device for medical rehabilitation, in which a walking wheel set and a wearable component are connected by a linkage component. When a patient uses the device for assisted walking, bending of the lower leg will drive the third connecting plate to rotate, and the rotation of the third connecting plate will drive the first linkage rod and the second linkage rod to rotate, and the rotation of the first linkage rod will drive the eccentric wheel to rotate (the eccentricity of the third connecting plate, the first linkage rod, the second linkage rod and the eccentric wheel is equivalent to a four-bar linkage, the third connecting plate is used as a driving active member, and the eccentricity of the eccentric wheel is used as a rotating driven member). Since the eccentric wheel is coaxially fixedly connected with the linkage active bevel gear, the rotation of the eccentric wheel will drive the linkage bevel gear set (The linkage active bevel gear and the linkage driven bevel gear) rotate, and the linkage bevel gear group rotates under the action of the linkage shaft, driving the transmission bevel gear group (the transmission active bevel gear and the transmission driven bevel gear) to rotate, and the transmission bevel gear group rotates to drive the walking wheel group to rotate, and the walking wheel group rotates to drive the entire walking assistance device to move, thereby helping the patient to walk; and under the action of the linkage component, the patient's calf will bend when he actively walks, and the walking wheel group will rotate to drive the entire walking assistance device to move, and when the patient stops, the calf is fixed and the walking wheel group cannot rotate, thereby ensuring the stability of the entire walking assistance device and further improving the safety factor of the device.
