technical field

The invention relates to an adjustable airbag pillow

Background technique

During the average human sleep of about 7 to 9 hours a day, the body regulates, repairs and grows itself. Sleep has an important impact on people's physical and mental health and mood.

The influence of sleep posture on sleep apnea has attracted extensive attention of many scholars. In recent years, a lot of research work on analyzing the relationship between sleep apnea and sleep posture has also made great progress. Studies have reported that the lateral sleeping position is effective in reducing sleep disturbances in patients with moderate/mild sleep apnea syndrome. Supine sleeping positions should be avoided in patients with respiratory problems. Abnormal breathing occurs in patients with postural obstructive sleep apnea when they sleep in the supine position. However, in the lateral position, their occurrence of apnea and hypopnea was significantly reduced or even completely eliminated. Therefore, real-time recognition and adjustment of sleep postures will effectively alleviate sleep-disordered breathing in patients with sleep apnea.

Studies have found that maintaining a sleeping position can also have an impact on sleep quality. Different sleeping positions have their pros and cons.

One, side sleeping. Sleeping on your side is suitable for those with chronic back pain, snoring or acid regurgitation during sleep, including those who are pregnant. However, there are also disadvantages to side sleeping. As a result of lying on one side of the face on a pillow for a long time, it will cause wrinkles on the face.

Two, supine. Sleeping on your back also has many benefits, as long as you use the right pillow, you can easily keep your head, neck and spine back, allowing your back to relax and stay asleep. The correct pillow height keeps your airway open and aligns your cervical spine with your neck. However, the pillow you use should be the right height to lift our head slightly so that the stomach is below the esophagus, preventing acid reflux. Sleeping on your back also keeps your face and chest open, preventing sagging and wrinkles. But lying on your back puts your tongue in a position that blocks the airway or creates pressure, which can exacerbate sleep apnea and snoring.

Three, lie down to sleep. When you sleep on your stomach, your body's center of gravity sinks deeper into the mattress, while your limbs and head remain higher on the surface, causing serious damage to your spine, as well as your neck and back. pain. At the same time, physical stress increases stress on muscles, joints, and body organs. Because you're shifting positions frequently during sleep, because that's how your body stays comfortable, it also leads to more disturbances in your sleep, and you're just getting low-quality sleep.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the deficiencies of the prior art and provide an adjustable airbag pillow.

The technical scheme adopted by the present invention to solve its technical problems is:

An adjustable airbag pillow, which includes a pillow shell and a controller, the inside of the pillow shell is provided with two left and right airbags that are respectively controlled by an air pump to be inflated and deflated, and two airbags are arranged on the pillow shell. an air pressure sensor, the air pressure sensor is arranged above the air bag, a pulse sensor is respectively provided on the pillow shell near the pulse on both sides of the neck of the human body, and a sound sensor is also provided on the pillow shell; The air pressure sensor, the pulse sensor and the sound sensor are respectively connected to the controller by signals, and the controller respectively controls and connects the air pump, and the controller is also provided with a wireless transmission module that can be connected to a smart device; The device controls the air pump to inflate and deflate the air bag to set the initial state. When the signals sensed by the air pressure sensor, pulse sensor and sound sensor received by the controller fall within the normal threshold, it is judged that the user's sleep state is normal, and the controller controls the two air bags respectively. Inflate and deflate after a certain period of time to make the user change the sleeping position; when the sound sensor detects snoring, and the pulse sensor detects that the heart rate is too slow, which is lower than the normal threshold, it judges that the user's sleeping state is abnormal, and the controller controls the two airbags.

When the sleep state is normal, the airbag pillow will monitor the data of the air pressure sensor and the pulse sensor, and change a sleeping position at certain intervals. Avoid putting pressure on one part of the body for long periods of time.

When the sleep state is abnormal, that is, the sound sensor detects snoring. The airbag pillow will adjust to the side sleeping position by inflating and deflating until the snoring disappears.

When the sleep state is abnormal 2, that is, sleeping on the stomach or sleeping on the stomach, the pulse sensor cannot monitor the carotid artery data. The airbag pillow will be inflated and deflated to adjust to the initial sleeping position until the pulse sensor monitoring returns to normal.

When the sleep state is abnormal three, that is, the nightmare state, the pulse sensor detects that the heart rate increases. The airbag pillow will quickly inflate and deflate the left and right airbags, so that the pillow shakes the head until the user wakes up and the heart rate returns to normal.

Other abnormal sleep states, such as teeth grinding, sleep talking, etc., are similar to the above adjustments.

According to the user's choice of a suitable size of pillow 1, the pillow core 2 lies on the center of the pillow, the inflation and deflation connecting pipe 5 is connected to the controller 62, the power is turned on, and the control panel button 61 is activated. You can sleep normally.

Manual mode: select manual by pressing the button, operate the inflation and deflation buttons to inflate and deflate the airbag, and control the height and shape of the pillow. Repeat as many times as necessary.

Manual inflation and deflation control. 1. According to the user's subjective feelings. 2. Judgment based on the experience of the auxiliary user.

Automatic mode: select automatic by pressing the button, and then select the inflation and deflation speed.
