Technical Field

[0001] The present invention belongs to the technical field of assisted walking, and in particular relates to a medical rehabilitation walking aid device. Background Art

[0002] Medical rehabilitation walking aids are medical devices used to assist patients in regaining their ability to walk and improving limb function. They are widely used in rehabilitation training for patients with stroke, spinal cord injury, limb injury, and other conditions. They play an important role in helping patients regain their ability to walk and improve their quality of life. With the continuous advancement of technology and policy support, their application prospects will be even broader.

[0003] Existing assistive walking devices can only provide basic support measures for patients, but patients with weak walking ability have poor balance ability and are at risk of falling when using walking devices to move, which may cause secondary injuries to patients. Traditional walking devices lack protection against falls and are inconvenient to use.

[0004] Therefore, those skilled in the art have proposed a medical rehabilitation walking aid device to solve the problems raised in the background art.

[0014] Preferably, a positioning slot is provided on one side of the adjustment rail plate, a positioning screw hole is provided on one side of the adjustment slider, a positioning screw is provided in the positioning slot, and the positioning screw passes through the positioning slot and is screwed into the positioning screw hole.

[0015] Preferably, a cross bar is fixedly mounted on the second support rod, a rotating plate is mounted on the cross bar, a rotating hole is provided on the rotating plate, and the rotating plate is movably engaged with the cross bar through the rotating hole.

[0016] Preferably, one end of the rotating plate is fixedly connected to a temporary cushion, the temporary cushion includes a storage bin inside, a plurality of counterweights are placed inside the storage bin, a hinge is provided on one side of the storage bin, and a sealing plate is hinged on the hinge.

[0017] Preferably, a second magnetic block is provided on the sealing plate, and a first magnetic block is provided at one end of the storage bin, and the first magnetic block is magnetically matched with the second magnetic block.

[0018] Preferably, a storage plate is fixedly connected between the first support rod and the second support rod, a side surface of the storage plate is provided with a built-in slot, and a retractable baffle is movably installed at one end inside the built-in slot.

[0019] Preferably, a universal wheel and a limiting rod are provided at one end of the first support rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention can provide patients with basic support measures for assisting walking by setting up a support structure with a first support rod, a second support rod and an armrest. At the same time, a protective cushion with a trigger component and an airbag accommodating chamber are installed on the armrest. When the patient falls accidentally, his body will fall forward. At this time, the patient's chest will be against the protective cushion, and the protective cushion will be squeezed, causing the telescopic rod and the telescopic cylinder to slide telescopically. The telescopic rod slides inward and transmits the air in the telescopic cylinder to the inside of the inflatable airbag through the transmission airway, so that the inflatable airbag can be inflated in time, thereby providing effective protection for the patient's head. In addition, the height of the entire protective cushion and the airbag accommodating chamber can be adjusted by sliding the adjustment slider and the adjustment groove, so that it can adapt to patients of different heights and body shapes.

[0022] (2) The present invention provides a temporary seat cushion with a counterweight. When the user walks, the temporary seat cushion will naturally fall down under the action of the rotating plate. At this time, the internal counterweight can act as an additional mass block, called a tuning mass. The swing of the mass block during walking is used to offset the vibration of the main structure, thereby achieving the purpose of stability. This can make the entire walking aid more stable and reduce the chance of the patient falling down when using it. When the patient is tired of walking, the temporary seat cushion can be rotated to a horizontal state, and the retractable baffle can be rotated to the bottom of the temporary seat cushion to provide a limit for it, thereby forming a temporary chair to provide the user with a temporary rest.

[0023] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
