In one example embodiment, a vibration apparatus can augment and enhance negative-pressure therapy systems. The apparatus can be attached to an external surface of a dressing, fluid conductor, or other components. The apparatus can generate low-amplitude vibrations, which can be transmitted through the components. Kinetic energy of the oscillations can agitate fluid in the components, which can lower the viscosity of the fluid and reduce the frequency of blockages in fluid conductors. Vibrations may also agitate a tissue site, which can encourage blood flow and granulation.
