FIELD: medicine.
SUBSTANCE: invention refers to acoustically controlled for respiratory activation assistance. An air inhalation device for medicine delivery to the user comprises an acoustic controller accommodating an acoustic sensitive element detecting noise of air flow in the device and generating signals of detected noise, and a signal processing circuit to identify the direction and amplitude of air flow, as well as a high-frequency discharging a medicine into air flow when the processed signals identify inhalation by the user. The direction of air flow stream is identified with the circuit by measuring the instantaneous voltage offset generated by the acoustic sensitive element.
EFFECT: invention allows improving application of the preparation owing to ensured release of the medicine in a proper point of time.
