Abstract: Disclosed is a device for stimulating the tracheobronchial air of a patient suffering from an obstructive ventilatory disorder and able to modify the rheology of his tracheobronchial mucus, which includes a negative pressure generator, a physiological interface able to interface the device with the patient's respiratory apparatus, a connection pipe connecting the physiological interface to the negative pressure generator, and a control circuit capable of controlling the negative pressure generator, during the passive expiration phase, for the application of a succession of alternation of negative pressure and venting impulses with a determined frequency and a duty cycle determined during a first part of an expiration cycle and then a second frequency and a second duty cycle during a second part of the expiration cycle and to reiterate a defined number of expiration cycles.

Abstract: An automatic control system for a tracheobronchial-air stimulation device intended to be connected to a subject. The stimulation device is configured to generate a set of negative pressure pulses during a relaxed exhalation of the subject. Also, a method for automatically controlling the tracheobronchial-air stimulation device, and a computer program and non-transitory computer readable medium, each of which comprise instructions for implementation of the method.

Abstract: Equipment for treating obstructive lung disorders includes: a respiratory nozzle (2) including at least one air filtering element (21) and at least one transponder (22) on which is recorded a unique identifier and elements for storing information characterising the use of respiratory nozzle, and a device (1) designed for facilitating expulsion of mucus, and including at least one receiver (11) associated with the transponder and which only allows initiation of the device after detection of the unique identifier, which device includes at least one microcontroller (12) for the management of the transponder, which is designed both for reading information of this transponder and for modifying the information so as to prevent the use of the respiratory nozzle when the latter has already been used once by a patient or to prevent the initiation of the device if the number of uses of respiratory nozzle is greater than a predetermined threshold.
