Hydrotherapy massage method and apparatus

摘要

A hydrotherapy method and apparatus for discharging a water stream through a rigid conduit while concurrently translating the conduit discharge orifice along a nonlinear path describing an area. The conduit is comprised of a supply section and a discharge section having an axis misaligned with the supply section axis for discharging a stream in a direction tending to rotate the conduit around the supply section axis. Frictional loading of the conduit, attributable to suction produced by the supply water jet, is mitigated by providing a passageway which permits the suction to draw tub water into a cavity for entrainment by the water jet for discharge through the conduit.
