It should be pointed out that the connection mode between the control panel 6 and the display screen 7 and the controller is the prior art.

The working process of the present utility model is:

When in use, the patient lies on the airbag layer of the mattress body, and the pressure applied by the patient to the airbag 1 is monitored through the pressure sensor 2. When the pressure detected by the pressure sensor 2 is lower than the first set threshold, the controller controls the corresponding airbag The intake control valve 12 on the intake pipe 11 of 1 is opened, the intake control valve 12 on the intake pipe of other airbags 1 is controlled to close, and the airbag 1 is inflated through the air pump 5 until the monitored pressure exceeds the first setting Threshold, stop inflation; when the pressure sensor 2 monitors the pressure to exceed the second set threshold, the controller controls the exhaust valve 13 on the intake pipe 11 of the corresponding airbag 1 to open, so that the airbag 1 is exhausted until the monitored pressure is less than The second sets the threshold and stops exhausting. Wherein, the first set threshold is smaller than the second set threshold, and the induced pressure of the pressure sensor 2 is maintained within the range between the first set threshold and the second set threshold, which can improve the comfort of the patient on the mattress body .

On the other hand, when in use, the timer 3 is used to monitor the interval between the inflation and exhaust of the airbag 1, and the airbag 1 is alternately inflated and exhausted every time the set time is reached. For example, when the set time is 30 minutes, the airbag 1 is first inflated so that the pressure sensor 2 monitors that the pressure exceeds the third set threshold, the inflation is stopped, the timer 3 starts counting, and after 30 minutes, the airbag 1 is exhausted. The pressure sensor 2 monitors that the pressure is less than the fourth set threshold, stops the exhaust, and so on. Wherein, the third set threshold may be equal to the first set threshold, and the fourth set threshold may be equal to the second set threshold.
