Bathtub design with therapeutical treatment devices

A hydro-thermo massaging tub comprising:

• an open-top-end enclosure including a bottom wall, opposed sidewalls and opposed end walls;
• means for draining water from an inner chamber defined by the tub;
• an air distribution duct associated with at least the sidewalls and end walls;
• a plurality of holes of predetermined dimension disposed at least in the sidewalls and end walls, and at predetermined spacing all around the tub and communicating the air distribution duct with the inner chamber to form air jets;
• an air blower connected to the air distribution duct for directing air under pressure in the duct;
• whereby the air under pressure is released through the plurality of the holes as air bubbles in a body of water contained within the inner chamber to impart turbulence in the body of water to create acupressure massaging flows of air jets and water from opposed sidewalls and end walls towards a central area of least turbulence in the inner chamber such that when a bather occupies the area of least turbulence, the massaging flows will perform a hydro-thermo massaging action simultaneously about the bather's body;
• an ozone injection system to inject ozone in the air distribution duct downstream of said air blower so that an ozone-mixed air flow sterilizes the air distribution duct, and the air bubbles in the body of water contain ozone to purify the body of the water and to clean the skin of the bather's body;
• said ozone injection system including an ozone generator regulated to generate ozone in quantities between 0.003 and 0.01 ppm and a vacuum generator connected to said ozone generator by a vacuum pipe, a bypass conduit between an inlet of said air blower and said air distribution duct to create a pressure differential and an air flow in said bypass conduit, said vacuum pipe being connected to said bypass conduit whereby said air flow in said bypass conduit will create a suction in said vacuum pipe to draw ozone in said bypass conduit to inject same in said distribution duct downstream of said air blower.
