Description

An improved standing balance rehabilitation training device Technical Field

[0001] This utility model specifically relates to an improved standing balance rehabilitation training device, belonging to the field of rehabilitation medical device technology. Background Technology

[0002] For patients with hemiplegia or cerebral palsy caused by stroke, congenital nerve injury, poliomyelitis, etc., most have motor impairments and require lower limb rehabilitation training during clinical treatment. Standing balance rehabilitation training can help patients exercise their lower limbs, thereby achieving a recovery from standing to walking. Currently, there are various standing balance training devices. For example, application number 202222249214.5 describes a standing balance training device including an upper irregularly shaped tube with a tabletop fixedly connected to it. Two support tubes are fixedly connected below the tabletop, and the lower ends of both support tubes are fixedly connected to the upper ends of corresponding resistance springs. The lower ends of the resistance springs are fixedly connected to supports, which are fixedly connected to a base. The supports are located in a bottom cylinder, which is fixedly connected to the base. The device slides on the support tubes. The device features a conical sleeve with a compression spring fitted on it. A limit sleeve is fixedly connected to the support tube at the upper end of the compression spring. The upper end of the compression spring rests against the limit sleeve, and the lower end rests against the conical sleeve. A pull-wire controller is fixedly connected to the upper part of the standing balance training device, with the lower end of the pull wire connected to the conical sleeve. A lumbar support frame is connected to the upper part of the support tube, and a leg support frame is connected to the lower part of the support tube.

A second spring pin is also provided on the transition block, and multiple second positioning holes are provided on the support arm. The second spring pin cooperates with the second positioning holes to fix the support arm.

[0008] Beneficial effects: This utility model, by setting a rotating shaft on the guide sleeve, allows the crossbeam to be rotatably connected to the rotating shaft. At the same time, a retaining ring is fixed to the square head of the rotating shaft by a bolt with a knob. In this way, the retaining ring can prevent the crossbeam from falling off the rotating shaft without affecting the rotation of the crossbeam. This greatly improves the connection reliability and flexibility of the standing balance rehabilitation training device during forward, backward, left and right swaying. In addition, by cooperating the first spring pin with the first positioning hole and the second spring pin with the second positioning hole, the two sets of knee guards can be adjusted in two degrees of freedom in the left-right and forward-backward directions, which is convenient for patients to use.
