<p>The device has an exsufflation end fitting for generating control signal according to the breathing of a user. An electrostimulator is connected to butterfly or boomerang electrodes, and generates electrical signals according to the control signal, where the electrical signals are in the form of symmetric bipolar current. The end fitting has units for generating sound wave in a given frequency field corresponding to the control signal. The electrostimulator has a sound wave sensor sensible to the field, and triggers the genesis of the electrical signals according to the control signal.</p> |
