Description

Sitting posture detection and adjustment device for students

Technical Field

The utility model relates to a position of sitting detects adjusting device technical field specifically is a student detects adjusting device with position of sitting.

Background

With the recent acceleration of social modernization, the incidence rate of myopia is increasing, and myopia has become one of the eye diseases with the highest incidence rate worldwide. According to data display, about 500 more than ten thousand blind people, 600 more than ten thousand low-vision people and 1000 ten thousand children with oblique amblyopia exist in China. The average myopia rate of teenagers reaches 40%, and the myopia rate of college students is far more than 70%. The reason is greatly related to the incorrect sitting posture of students. Incorrect sitting posture of students is mostly caused by bad habits. The teachers, students and parents do not pay enough attention, and the writing posture is not important as long as the children have good learning performance, and the results are habituated to nature. Although many teachers want to guide students to adjust sitting postures, the requirements of the teachers on writing sitting postures are not specific, the guiding training is difficult to implement, the students cannot operate, and finally, the teachers can only tie up the students ineligibly. Once the habits of a person are developed, they become extremely difficult to modify.

Poor sitting posture can cause a student's vision to decline. The eye adjusting force is strong in teenagers, the eye adjusting device has high adaptability to near distance work and study, and near distance vision is not easy to fatigue. However, if students read and write at a short distance for a long time without adding a care to protect eyes, ciliary muscles can be over-tensed, and then fatigue and even spasm occur, and the accommodation myopia occurs. If the accommodation myopia is not eliminated in time, the continuous development can be converted into irreversible true myopia. The poor sitting posture can cause the fatigue of neck muscles, cause neck and shoulder pain, neck muscle spasm and even cause light headedness; over time, cervical disc degeneration will occur prematurely after adulthood, leading to cervical spondylosis. Especially, some children love the dielang and the legs, continuous load can be caused to the neck and the back, so that muscles and ligaments on the back are excessively pulled and damaged for a long time, thereby causing idiopathic lumbago, long-term sitting posture is incorrect, coccyx injury is caused by pressing coccyx nerves, coccyx pain symptoms are caused, the symptoms comprise pressure pain points or leg pain phenomena near the coccyx of the hip, and the symptoms comprise coccyx, levator ani muscle, surrounding soft tissues and the like.
