Description

Technical Field

[0002] Alzheimer's disease (AD) is a progressive neurodegenerative disease with an insidious onset. It is clinically characterized by comprehensive dementia manifestations such as memory impairment, aphasia, apraxia, agnosia, visual-spatial skill impairment, executive dysfunction, and personality and behavioral changes. The cause of the disease is still unknown. Those who develop the disease before the age of 65 are called early-onset dementia, and those who develop the disease after the age of 65 are called senile dementia. Alzheimer's walking assistive device is an assistive device specially designed to help elderly people walk. This assistive device is designed to provide additional support and stability, thereby enhancing the balance and walking ability of the elderly. Elderly assistive walking devices can provide elderly people with safer, more comfortable and reliable walking assistance, while also reducing the pressure on caregivers. The popularization and application of this device will help promote the independence of the elderly and improve their quality of life.

[0003] When using the existing auxiliary walking device, the Alzheimer's patient needs to hold the handrail so that the Alzheimer's patient can be supported when moving. However, the palms of the Alzheimer's patient are prone to sweat, which causes sweat to easily accumulate on the handrail, which will breed bacteria for a long time and affect the physical health of the Alzheimer's patient. At the same time, the walking ability of Alzheimer's patients may be different at different stages of the disease. Some patients are prone to fatigue after walking for a period of time. However, because some auxiliary walking devices are not provided with a rest structure, the patient cannot take a temporary rest, which increases the risk of falling and poses a threat to the patient's health.

[0041] By adopting the above technical solution, a cleaning sponge ring 402 is provided on the outer ring of the handle 302 in order to clean the handle 302 and prevent bacteria from remaining on the handle 302 .

[0042] A square box 404 is fixedly connected at the center of the bottom end of the installation box 401, a vertical plate 405 is fixedly connected between the inner walls of the square box 404 near the center, and a half-bevel gear 406 is rotatably connected at the center of the side end of the vertical plate 405.

[0043] By adopting the above technical solution, a square box 404 is arranged inside the installation box 401 in order to install the half-face bevel gear 406 and the bevel gear 1 408, so as to realize the lifting and lowering of the threaded cylinder 410.

[0044] A vertical shaft 407 is rotatably connected between the inner walls of the square box 404 and near the vertical plate four 405, and a bevel gear one 408 is symmetrically fixedly connected to the outer ring of the vertical shaft 407 near the half-bevel gear 406, and the two bevel gears one 408 are engaged with the half-bevel gear 406.

[0048] Working principle: When the present invention is used, when the patient needs to rest after training for a period of time, by pressing the straight board 210, the two sliding shafts 208 and the sliding shaft 3 209 can be made to deviate in angle under the action of the side grooves 206 and 5 207 until the straight board 210 is moved and laid flat to the bottom end of the installation box 201. At this time, the sliding shaft 1 203 in the two side grooves 1 202 will drive the seat board 204 to move out of the installation box 201 under the mutual cooperation between the spring 205 and the connecting shaft 211 and the long groove 214 and the rotating shaft 1 212. Then the patient can sit on the seat board 204, so that the patient can rest, thereby solving the problem that the patient cannot take a temporary rest, the risk of falling is increased, and the health of the patient is threatened.

[0049] When the patient is training outside and the sun appears, the motor 1 317 can be operated to rotate the fixedly connected screw rod 1 315, thereby causing the vertical block 316 connected by the threaded rotation to drive the plug shaft 313 to move horizontally inside the vertical plate 1 309. At this time, the vertical plate 2 311 will move horizontally under the action of the guide telescopic shaft 310, thereby realizing the work of unfolding the telescopic awning 312, thereby preventing the patient from being exposed to the sun during training, thereby ensuring the patient's comfort during use. When the device needs to be cleaned after using it for a period of time, the cleaning liquid is added to the water storage box 307, and then the two spray frame bodies 304 and the motor 2 417 are opened, so that the cleaning liquid is sprayed to the outer ring of the handle 302, and the motor 2 417 can drive the tank 304 to move horizontally. The wheel 415 rotates, and then with the cooperation of the two rack gears 1 414, the square frame 413 can drive the rack gear 2 416 to move back and forth horizontally, and then the rack gear 2 416 drives the meshing first gear 411 to rotate back and forth, and the fixedly connected half-face bevel gear 406 will rotate back and forth, and then the two meshing bevel gear gears 1 408 will drive the vertical shaft 407 and the screw rod 2 409 to rotate, and the threaded cylinder 410 connected to the threaded rotation drives the fixedly connected connecting rod 403 to move up and down, and with the cooperation of the cleaning sponge ring 402, the handle 302 can be cleaned, thereby solving the problem that the palms of Alzheimer's patients are prone to sweat accumulation on the armrests, which will breed bacteria for a long time.
