Abstract
A hand-held dry hydro-massage unit for use in a spa tub to allow the user to direct the soothing effects of the hydro-therapeutic massage to specific portions of the body. The hand held unit is normally used in conjuction with a hydrotherapy spa tub to provide separate air and water supplies to the unit. The air and water are mixed by a discharge jet which forces the mixture onto the inside surface of a flexible diaphragm. The diaphragm encloses the unit such that the water is not discharged but is returned back through the supply line to the tub. The unit therefore provides a dry massage of the user eliminating the annoying water discharge and splash of conventional hydro-therapy devices.
