Abstract
Device comprised of a container (3) associated to a pump (4), and intended to the forced expectoration of pulmonary mucus by generating in the total air volume of the lungs controlled oscillatory variations of pressure, frequency and amplitude up to optimum valuesso as to achieve the thixotropy of the mucus, the device being characterized in that the container (3) forming the oscillatory pressure variator contains an air volume to which is applied suddenly and cyclically a progressive oscillatory depression and communicates with the air of the lungs through a flexible hose (2) and a respiratory mask (1). The device has two conduits (6) to communicate the air contained in the lungs and the hose (2) with the tympanums.
