Auxiliary moving mechanism for preventing old people from falling down

Abstract

The invention discloses an auxiliary moving mechanism for preventing old people from falling down, which comprises a support frame and support legs, the lower ends of the supports are provided with rollers, the support frame further comprises a waist component, auxiliary cylinders mounted on both sides of the support frame and a support mechanism capable of being automatically unfolded, and each auxiliary cylinder is provided with an upper cavity and a lower cavity. a pair of supporting mechanisms each comprises a supporting leg, the extending end of a piston rod of the auxiliary cylinder is connected with the left side and the right side of the waist assembly through connecting belts, and the waist assembly is internally equipped with a on-off valve, a tension three-way valve and an anti-falling detection device capable of detecting the posture of a human body. Opening and closing of all air inlets of the tension three-way valve are controlled by judging whether tension of the connecting belt is balanced or not, and the balanced air outlets of the lower cavities of the two auxiliary cylinders are connected to the same balance exhaust port provided with a first flow limiting valvethrough the tension three-way valve. According to the invention, the support of the auxiliary cylinder can reduce impact of users when falling again, and help users keep balance in moving process, andreduce influences caused by uneven ground.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to an auxiliary movement mechanism for preventing the elderly from falling. Background technique [0002] Due to the natural decline in physical fitness, the elderly will weaken their muscle strength and body flexibility, and their sensitivity, balance, and coordination will decrease, so they are prone to falls. Some elderly people are also prone to dizziness due to unhealthy blood pressure and heart. A device for assisting support during walking. Existing auxiliary support devices include a walking stick supported by the old man, a support frame that moves with the old man through rollers around the old man's body, and an auxiliary support device bound on the old man's body. Since the cane requires the upper limbs of the elderly to assist in support, if the elderly lacks strength or suffers from vertigo, there is no guarantee that the elderly will not fall. However, the supporting ...
