Alternate inflation and deflation time intervals (recommended to be set for 10 minutes, 30 minutes and 60 minutes) are set on the upper computer, and pipelines are connected to the first ventilation air bag and the second ventilation air bag and are used as gas inlets. The small-size gas outlet is installed at the afterbody of the twenty-fifth air-exchanging air bag and the twenty-sixth air-exchanging air bag, the air inlet speed is about twice of the air outlet speed, and the air bags of the upper air cushion bed are alternately inflated, so that the stressed area on the back of a patient is changed frequently, the stressed points on the back of the patient can be converted, the comfort degree of the patient is increased, and the bedsore is reduced. When the alternate inflation function is closed, the small air holes at the tail part are closed, the instrument can fill the air in the two groups of air bags (the air pressure sensor sets a proper numerical value and transmits a signal to the upper computer).
In the upper air cushion bed, six defecation sensors are mounted on the thirteenth, fourteenth, fifteenth, sixteenth, seventeenth and eighteenth ventilation air bags near the middle, information is transmitted to the single chip microcomputer through wireless transmission, and whether the patient has the defecation incontinence condition or not is judged through calculation. If the incontinence of urine and feces exists, an alarm is given out on the upper computer.
