Elbow support rollator

Abstract

With the aging of the population, falling has become an important cause of disability and death for the elderly over 65 years old in my country. As age increases, physical strength and balance ability weaken, and there is a lack of effective auxiliary support devices for "instability" falls. The elbow-arm support walker of the present invention is designed to provide users with a tool that fully supports the body to assist walking and protect the user. The elbow-arm support walker adopts a U-shaped elbow support handle (20), the height of which is adjusted to the most suitable height for the user according to the distance between the user's elbow and the ground. The user's weight is transferred to the U-shaped support handle frame (13) on the walker through the elbow, and is connected to the handlebar fixing tube (6) and the walker support tube (5) and the walker frame (1) supported on both sides. The rear wheel of the vehicle adopts a large wheel with good passability. The person is located in the center of the vehicle body, which can avoid the risk of "instability" falling, and supports walking throughout the whole process, reducing the pressure on the shoulders, back, waist, legs, and knee joints. The foldable design is convenient for transportation and storage, and the structure is simple and easy to use.
