1. A device (10) for facilitating coughing based on oscillating pressure, wherein the oscillating pressure causes a periodic oscillating air flow in the pulmonary system, and the periodic oscillating air stream contains an oscillating exhaled air stream and an oscillating inhaled air stream, and the device (10) comprises a unit (11) a control comprising: a first detection unit (111) for determining whether the inhalation of the pulmonary system is completed to control a valve (13) that is to be closed for isolation from the external environment, - a second detection unit (112) for determining whether the internal air pressure in the pulmonary system is higher than a predetermined pressure threshold, and - a detection unit (113) for detecting the onset of oscillating exhaled air flow to control the valve (13), which must be opened to initiate coughing. 2. The device according to claim 1, in which the first detection unit (111) is configured to determine whether the inhalation of the pulmonary system is completed when the speed of the inhaled air flow in the pulmonary system is lower than a predetermined speed threshold. The device according to claim 1, further comprising an oscillation unit (12) for providing oscillating pressure to excite oscillations of the pulmonary system to cause periodic oscillatory air flow in the pulmonary system. A method of promoting coughing based on oscillating pressure, wherein the oscillating pressure causes a periodic oscillating air flow in the pulmonary system, and a periodic oscillating air flow of soda1.
