<p>An air pressure self-adjustable medical mattress comprises several air bags arranged and fixed on a mattress. The air bags are communicated with an inflation tube. An air pump and an inflation and exhaust control valve inflate and exhaust the air bags to form a fluctuation mattress that is inflated and exhausted periodically. An inside of each air bag is separated by an air bag separation layer into an upper air chamber and a lower air chamber. The upper and lower air chambers are connected to the inflation tube respectively. Through alternating inflation and exhaust of the upper air chamber, a body of a patient is massaged when being squeezed and relaxed, thus bedsores of the patient can be prevented and treated.</p> |
