ABSTRACT:
A width-adjustable alternating air inflation mattress has a body. At least one lateral side of the body is added with tubular air cells for increasing the width of the bed body. The inflation of the tubular air cell is controlled by air valves. When the tubular air cells are inflated, the width thereof is increased. By above mentioned alternating air inflation mattress, in normal use, the alternating air inflation mattress has a sufficient wide and thus the patient can lie upon the bed comfortably. If it is desired to pass the alternating air inflation mattress through the door, it only needs to evacuate airs in tubular air cells at two sides of the bed to reduce the width of the bed. Other than the inflation of the tubular air cells being controllable, if the patent needs a first aid, the air in the tubular air cell can be evacuated out rapidly for executing CPR.
