Adopting advanced 3D spiral vibration technology, the motor shaft drives an eccentric rotor at a precisely set rotational speed, generating mechanical vibrations at specific frequencies. Under precise control by a high-efficiency vibration damping system, vibrations are transmitted to the surface of the treatment head, creating horizontal and vertical components. The vertical force relaxes and liquefies mucus and metabolites on the surface of the bronchial mucosa, while the horizontal force facilitates the flow of mucus from smaller bronchi into larger bronchi. Combined with coughing, this effectively assists expectoration. In addition, the device improves pulmonary blood circulation, aids in the removal of respiratory secretions, and provides strong support for patients’ respiratory health.
