Swimming pool therapy apparatus

Apparatus for generating a laminar flow in a reservoir containing water, said apparatus comprising:

• drive motor means disposed outside said reservoir;
• flow generating means disposed within said reservoir and submerged in the water therein;
• said flow generating means including an upper section nearest the surface of the water, a lower section submerged the farthest beneath the surface of the water, and an intermediate section between said upper and lower sections;
• said lower section having a water inlet therein to permit water to be drawn into said flow directing means and said upper section having a water outlet therein to permit water to be discharged from said flow directing means in a laminar flow pattern;
• impeller means disposed within said flow generating means above said water inlet;
• said flow generating means including three separate stages of flow diffusing means disposed between said impeller means and said water outlet, defining a first, second and third stage;
• each of said separate stages of flow diffusing means including a plurality of spaced vane members across which water passes as it traverses through said flow generating means from said water inlet to said water outlet;
• and
• means operatively connecting said impeller means to said drive motor means whereby operation of said drive motor means rotates said impeller means and thereby draws water from said reservoir into said water inlet;
• said operation of said impeller means further causing the water drawn in through said water inlet to pass across said three separate stages of flow diffusing means, which serve to laminarize the flow characteristics of the water, and then to discharge through said water outlet as non-turbulent laminar flow.
