Abstract
Pneumatic mattress with built-in inflation pump, which is essentially characterized by being constituted from a conventional mattress inside which, and in a suitable place, the pump itself is placed, constituted by a hollow body, prolonged by an end in a neck which will be the outlet valve of the air, and opposite it, an orifice with its corresponding plug, through which the outside air will pass through a valve, fill the reticles of a piece of highly spongy and porous material that is inside said pump, pressing on which, it will be achieved that the air stored in the spongy piece passes into the interior of the mattress, through the neck valve, which will close when not pressing on the pump itself, while the air inlet valve will open, allowing then the pores piece to be filled with air again, to press again to provide a new stroke, thus achieving that the mattress acquires the desired air pressure; having provided an exhaust valve intended to empty the mattress of air, when it ceases to be used, then can be rolled and transported comfortably.
