Mobilization and drainage of the deep bronchial mucus The Simeox signal can reach the peripheral airways of the bronchial tree to allow the mucus to be collected where it is most difficult to dislodge.

A feeling of regained breathing Simeox helps the patient to exhale, allowing him to better «empty» his lungs. The feeling of fresh air that then enters the lungs at the next inhalation gives the patient a real sense of well-being.

Reduced risk of bronchial collapse The Simeox device does not generate continuous flow. The very short negative pressure pulses, interspersed with atmospheric pressure, reduce the risk of bronchial collapse.

Fatigue-free drainage

The patient breathes at tidal volume and exhales in a relaxed manner, so there is no increased fatigue

Simeox benefits

A unique technology The signal delivered by Simeox exploits the biophysical properties of bronchial mucus, one of them being its thixotropic nature: it acts directly on the consistency of the mucus to liquefy it and transport it from the periphery of the lungs to the central airways.

Principle of operation

Simeox is easy to use. However, the handling of the device requires support from a healthcare professional.

The inspiratory and expiratory phases described below should be repeated several times during a session.

The patient inhales slowly through the nose, then briefly holds their breath to bring the air behind the secretions.

During relaxed exhalation, the patient activates the Simeox signal by pressing the GO button on the remote control: Small volumes of lung air are collected at a frequency of 12 Hz (6 Hz at the end of the cycle). This very fast air capture generates a negative pressure pulse in the bronchial tree. As the unit continues to withdraw air during exhalation, the generated negative pressure pulse increases, as shown on the graph below.

This succession of very short negative pressure pulses of increasing intensity diffuses a vibratory signal in the bronchial tree. This acts on the rheological properties of the mucus to reduce its viscosity.The liquefied mucus is simultaneously transported from the peripheral pulmonary zone to the central airways, and then naturally expectorated by the patient.
