Description

multifunctional computer chair

technical field

The present invention belongs to the field of office furniture, in particular to office health care products, in particular to a multipurpose chair for preventing and controlling computer office diseases.

Background technique

Sitting in a traditional office chair and working in front of a computer for a long time can lead to a variety of diseases, such as cervical spondylosis. The root cause of cervical spondylosis is that after cervical disc degeneration, the intervertebral disc loosens, and then compresses the nerve roots, spinal cord or vertebral arteries and causes various symptoms. Long-term poor sitting posture or staying in front of the computer for a long time is most likely to cause neck muscle fatigue, neck and shoulder pain, nuchal muscle spasm, and even dizziness; over time, cervical disc degeneration is bound to occur prematurely after adulthood, leading to Cervical spondylosis; lumbar spondylosis, due to long-term sitting, or some poor sitting posture, or always fixed in a posture, the soft tissue of the waist is in a state of tension for a long time, and the soft tissue ischemia, resulting in lumbar muscle strain; coccyx injury, symptoms of coccyx pain include There are tender points or leg pain near the coccyx of the buttocks, including the coccyx, levator ani muscle and surrounding soft tissues. Improper sitting posture for a long time can compress the coccyx nerve, which can cause coccyx injury and pain; muscle soreness, hundreds of millions of cells in the human body rely on blood transportation to complete their metabolic functions, sedentary can reduce the amount of oxygen-carrying blood in the body, oxygen content Decreased blood pressure and increased carbon dioxide-carrying blood volume increases the partial pressure of carbon dioxide, causing muscle soreness, stiffness, and atrophy.

Existing office chairs have also proposed adjustment functions, but the adjustment range is relatively small and has little effect on various diseases.
