Backward walking rearview mirror

Abstract

The invention discloses a backward walking rearview mirror which comprises a first pipe, a second pipe and a reflector, wherein the first pipe is a telescopic pipe; when an elastic limiting bump is accommodated into a recess of a folded position, the first pipe is parallel to the second pipe; when the elastic limiting bump is accommodated into a recess of an expanded position, the first pipe is vertical to the second pipe; a third magnet and a fourth magnet or an iron body are attracted by each other; when a guide bump is located in a groove of the expanded position, a connecting rod, the first pipe and the second pipe are located in the same plane; and when the guide bump is located in a groove of the folded position, the connecting rod is vertical to the plane in which the first pipe and the second pipe are located. The accommodating volume of the backward walking rearview mirror is reduced.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, and in particular relates to a reversing rearview mirror. Background technique [0002] Walking backwards can relax the lower back, exercise the spine and lower back muscles, and prevent and treat lumbar diseases. In addition, since the knee joint does not need to be bent when walking backwards, the femoral muscle bears more gravity, so that the muscles, ligaments, and femoral muscles of the knee joint can be exercised to prevent knee joint diseases. For patients with lumbar intervertebral disc disease, medical staff need to instruct patients to perform backward walking exercises for a certain amount of time every day to promote recovery. In clinical work, when the patient is performing slow backward walking, because the patient cannot look directly at the rear, he can only look at it by turning his head. There is a safety risk of falling. Due to the constant turning of the head, there...

AI Technical Summary

Problems solved by technology

In clinical work, when the patient is performing slow backward movement, because the patient cannot look directly at the rear, only by turning the head to watch, there is a safety risk of falling, and there is also a risk of dizziness or cervical spine injury due to the constant turning of the head

Furthermore, because the patient cannot accurately see the rear vision situation, he cannot exercise well, which affects the expected rehabilitation effect
