This invention discloses a vibration-type respiratory
sputum clearance device, relating to the field of
medical device technology. It includes a
vest body. Multiple independent liquid-coupled vibration units are arranged on the inner side of the
vest, corresponding to the upper and lower lobes of both lungs and the projected
lung region on the back. Each liquid-coupled vibration unit includes a sealed liquid-sealed bag, and a vibration unit is disposed on the outer side of each sealed liquid-sealed bag. The sealed liquid-sealed bag is integrally embedded and fixed in a flexible interlayer on the inner side of the
vest. The interior of the sealed liquid-sealed bag is filled with a vibration-transmitting liquid. The vibration-transmitting liquid filled in the sealed liquid-sealed bag of this invention, relying on its incompressible and highly fluid physical properties, can efficiently transmit and convert the high-frequency micro-vibrations generated by the double-layer piezoelectric sheet, forming a dual mechanical action of shallow loosening and deep oscillation, perfectly adapting to the
sputum clearance needs of the soft tissues of the chest and back and the deep airways of the
thoracic cavity.
