Abstract

The invention is suitable for the technical field of walking aids, and provides a rehabilitation walking aid with an auxiliary correction function, which comprises a walking aid frame body, a correction mechanism and an active mechanism; the correction mechanism is triggered when detecting that the patient has excessive forward tilting posture, the push-back actuator is used for carrying out passive posture push-back on the chest of the patient to help the patient establish correct upright body feeling, and meanwhile, the driving mechanism is started to assist the leg of the patient to carry out coordinated movement through lifting and swinging actions. The invention reduces the risk of the patient toppling due to excessive forward movement of the gravity center by timely push-back correction on one hand, and actively intervenes when the patient is tired on the other hand, thereby not only ensuring the continuity of rehabilitation actions, but also relieving ache through the swing function of the crotch bone, and improving the safety, harmony and comfort level of rehabilitation training.

Description

Rehabilitation walker with auxiliary correction function Technical Field The invention relates to the technical field of walking aids, in particular to a rehabilitation walking aid with an auxiliary correcting function. Background The rehabilitation aid is an important medical aid tool for helping patients with lower limb dysfunction to recover walking ability, and is widely applied to the scenes of rehabilitation after fracture operation, cerebral apoplexy sequelae training, daily walking assistance of old people with hypomyodynamia and the like. The rehabilitation walker products commonly found on the market at present mainly comprise a traditional walker frame, a walker, an exoskeleton type rehabilitation robot developed in recent years and the like. The traditional rollator is widely applied due to the simple structure, low cost and convenient operation. However, with the advancement of clinical practice and research of rehabilitation medicine, it has been gradually found that conventional rollators have some inherent defects in practical use, which affect the rehabilitation effect of patients. On the one hand, conventional rollators have difficulty correcting abnormal gait of the patient, especially posture problems of excessive pronation. In the process of using the rollator, the patient often generates fear psychology because of worrying about falling down, and simultaneously, in order to push the vehicle forward more laborsaving, the body can unconsciously incline forward to form the posture of bending over and humpback. If the posture is maintained for a long time, the spine can bear abnormal load, so that lumbar retrogression is accelerated, the gravity center of a patient can be obviously moved forward, and the risk of forward tilting and falling is increased. More importantly, once this errant walking posture is cured, subsequent rehabilitation therapy will face greater challenges and may even cause irreversible gait abnormalities. On the other hand, the traditional rollator cannot effectively inhibit the upper limb compensatory behaviors of a patient, so that the normal rehabilitation training of the lower limb is affected. For patients with fracture or hemiplegia, the affected lower limbs often cannot be dared or cannot bear weight sufficiently due to pain or insufficient muscle strength. Under the support of the traditional rollator, the patient can naturally transfer most of the weight to the rollator through arms, so that a compensation mode of 'dragging the upper limbs with the lower limbs' is formed. Although the mode can enable a patient to walk in a short period, in the long term, the bone density of the lower limb at the affected side is difficult to recover due to lack of sufficient load stimulation, the muscle is continuously atrophic, the normal gait mode cannot be established, and finally, the rehabilitation process is blocked, and even the optimal recovery time is delayed. For this reason, a rehabilitation walker with an auxiliary correcting function is now proposed to improve the existing problems. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a rehabilitation walker with an auxiliary correcting function. In order to achieve the above purpose, the present invention provides the following technical solutions: the rehabilitation walker with the auxiliary correction function comprises a walking assisting frame body, a walking assisting device and a rehabilitation assisting device, wherein the walking assisting frame body comprises a frame body, an arm support arranged at the top of the frame body, and a handrail arranged at one side of the arm support; The correcting mechanism is arranged at the chest support part of the walking aid frame body and is used for carrying out push-back correction on a patient in an excessive forward leaning posture; The correction mechanism comprises a pressing component and a push-back actuator driven by the pressing component, wherein the pressing component is configured to push the push-back actuator to generate circular motion; The pressing assembly comprises an arc-shaped support, a pressing column arranged on one side of the arc-shaped support, a pressing block arranged on one end, far away from the arc-shaped support, of the pressing column, a movable frame arranged below the pressing block, and a roller device rotatably connected to one end of the movable frame, wherein the movable frame is elastically connected with the inner wall of the arm support; the push-back actuator comprises a bearing plate, arc plates symmetrically arranged on the bearing plate, arc racks arranged along the arc sides of the arc plates, and a driving piece arranged between the arc plates; the driving mechanism is arranged below the walking aid frame body and is configured to enable the injured legs of the patient to conduct compound motions including lifting and swinging when the patient leans forward in posture.
