Technical Field

[0001] This utility model relates to the field of walking assistance equipment technology, and in particular to a fall prevention device for elderly people with osteoporosis. Background Technology

[0002] Osteoporosis is a systemic bone disease caused by a variety of factors, resulting in decreased bone density and quality, destruction of bone microstructure, and increased bone fragility, making it prone to fractures. Osteoporosis is divided into two main categories: primary and secondary. Primary osteoporosis is further divided into three types: postmenopausal osteoporosis, senile osteoporosis, and idiopathic osteoporosis.

[0003] Fall prevention equipment is designed to help elderly people with mobility issues or those who have lost the ability to walk to take care of themselves and go out for walks like able-bodied people, through the support of the equipment.

[0004] However, traditional fall prevention devices for osteoporosis in the elderly are not suitable for elderly people of different heights due to the varying armpit heights. This results in a narrow range of applicability for the devices. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fall prevention device for elderly people with osteoporosis, aiming to improve the problem that in the use of existing devices, the armpit height of elderly people of different heights is different, which makes the device inconvenient for elderly people of different heights and thus leads to a narrow range of applicability of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fall prevention device for osteoporosis in the elderly, comprising a frame, with a first universal wheel provided on the rear side of the frame, a pedal crossbeam sleeve fixedly connected to the front side of the frame, wheeled base frames provided on both sides inside the pedal crossbeam sleeve, Torx handle screws threadedly connected to the interior of each wheeled base frame, Torx handle screws threadedly connected to the interior of each pedal crossbeam sleeve, a second universal wheel provided at the bottom of each wheeled base frame, a rack plate provided inside the frame, and a folding assembly fixedly connected to the top of each rack plate for storing handrails.

[0007] Furthermore, the folding assembly includes an armrest slot, which is fixedly connected to the top of the rack plate.
