Description

A functional pillow for improving the stressed state of cervical spine

technical field

The invention relates to the technical field of a functional pillow for improving cervical spondylosis, in particular to a functional pillow for improving the stressed state of the cervical spine.

Background technique

With the popularization of computers, office workers spend part of their time working through computer screens. Due to incorrect sitting posture and long-term lack of activities, the tendons in the cervical spine tendon stiffen, and the normal physiological curve of the cervical spine gradually disappears. Weakness, dizziness, nausea, etc. seriously affect the quality of normal work and life. In addition to taking medicines for the treatment of cervical symptoms, human beings spend at least one-third of their daily activities in sleep. Ordinary sleep pillows cannot effectively support the human cervical spine in a large area, resulting in the cervical spine not being effectively relaxed and maintained for a long time. The state of stress further worsens the symptoms of cervical spondylosis.

In order to improve the stress on the cervical spine during sleep, relevant technical personnel have devoted themselves to the research and development of cervical spine functional pillows. Medicinal pillows, vibrating massage pillows, and inflatable pillows have come out one after another, with various patterns. Medicated pillows cannot meet the needs of different groups of people. For example, the medicines in medicated pillows are not easy to replace. Some users only hope that the cervical functional pillow can relieve the stress on the neck and optimize sleep quality, so the medicines in medicated pillows are not needed. Although massage pillows can massage acupuncture points and improve blood circulation in the neck, for people with shallow sleep, the action of massage pillows will reduce the quality of sleep of users, so they cannot be further promoted. Inflatable pillows are usually used The fluidity of gas and the support force of air pressure can effectively support the suspended position of the neck and flexibly change the support position according to the flow of gas. To improve the sleep quality of ordinary users. But most of the inflatable pillows in the prior art adopt integral airbags, the air flow of the integral airbag-type inflatable pillows fluctuates greatly during the movement of the user's head, and the user's head is easy to fall off from the inflatable pillows and the comfort is poor; some inflatable pillows A plurality of airbags are set in the airbag, but because the location of the airbags does not meet the requirements of ergonomics and does not fully take into account the supporting effect of the external parts of the cervical spine (such as the face) during human sleep, it is more effective to play the role of the inflatable pillow; The functional role of the pillow, the technicians set up multiple functional structures on the inflatable pillow, which complicates the processing technology of the inflatable pillow and increases the cost of the inflatable pillow. The price cannot be accepted by the majority of consumers, and the popularization of the inflatable pillow cannot be completed. And the inflatable pillow of complicated structure is heavy, is inconvenient to go out and carry.
