The design of the pillow should conform to the physiological and anatomical structure of the cervical vertebra, otherwise it will damage the cervical vertebra, especially the cervical vertebra with cervical spondylosis. Therefore, the design of pillow shape and texture is very important for the prevention and treatment of cervical vertebra.

However, many pillows (including various medicated pillows) on the market at present do not conform to the physiological curvature of cervical spine. Therefore, it is imperative to design a pillow for treating cervical vertebra.

① Length of pillow: Generally speaking, the length is 40~60 cm. It can ensure that the cervical spine can always be supported when sleeping posture changes.

(2) Pillow height: except the elastic expansion part, it is the same as the fist height when a person lies on his back, which can make the back of his head slightly separate from the bed surface; When lying on your side, the height of the pillow should be one shoulder wide. These two different heights can ensure the normal curvature of cervical spine in supine position and lateral position. Too high or too low pillows should not be used, and the height should be 10~ 12 cm. Prone posture is a bad rest posture.

③ Shape design of pillow: one is cylindrical and the other is dumbbell. The design and manufacture of cylindrical pillows are very simple. Dumbbell-shaped pillow, the circular surface in the middle can match the shape of the nape of the neck, and the protrusions on both sides can effectively prevent the head and neck from being skewed, which helps to keep the position of the head and neck during sleep.

The two shapes of pillows have their own advantages and disadvantages when used. Cylindrical pillow can effectively exert traction on cervical spine, but it exerts great pressure on cervical spine, which is easy to cause local discomfort. Dumbbell pillow is comfortable to use, but the traction is insufficient. So pillows should be used according to different situations. If in a short period of time, you need more power to pull, you can choose a long cylindrical pillow; If the illness is very mild and requires long-term slight traction, you can choose dumbbell-shaped pillows.

④ Pillow core: Pillow core requires certain hardness and air permeability. If you can put some medicine or disk in the pillow core, you can also play a synergistic role of medicine and magnetic therapy. At present, there is a new material pillow abroad, which is a kind of gel.

Built-in polymer material can automatically deform with the change of head and neck position, and keep the position closely combined with neck at any time, which is worth popularizing.
