Abstract: A rotary occlusion valve for tracheotomy is described, used in the medical field, which allows the function of occluding the flow, both inspiratory and expiratory, of a particular patient, depending on his or her clinical condition or ventilatory limitations, thus permitting the execution of the two steps of respiration, inspiration and expiration. The valve consists in a device composed of a main body in the form of a cylinder inside which is a bearing, a safety grille, a tab, and an oxygen connection port. Said main body is joined to a rotary one-way valve containing a spherical ball, an orifice in its center, windows, pillars, and a tab. Finally, the one-way valve contains a membrane consisting of a grip port and a diaphragm.
