FIELD: medicine.
SUBSTANCE: group of inventions refers to medicine. A method for facilitating expectoration on the basis of oscillation function, which generates an oscillating air flow in the pulmonary system is implemented by means of a device for facilitating expectoration. The above air flow contains an oscillating exhaled and oscillating inhaled air flows. A control unit of the above device comprises first and second identification units and detection units. The first identification unit is used to state if the pulmonary system has completed an inhale to control a valve to be closed to isolate the pulmonary system from the external environment. The second identification unit is used to state if an inner pressure in the pulmonary system is more than a pre-set pressure threshold. The detection unit is used to detect the beginning of the oscillating inhaled air flow to control the valve to be opened for the onset of coughing.
EFFECT: using the group of inventions enables more effective facilitating expectoration.
