Abstract: A tube flushing device has a shell having a first housing and a second housing connected on a side thereof so as to be movable between an open position and a closed position. A first pair of wheels are rotatably mounted in the first housing. A second pair of wheels rotatably mounted in the second housing. The first pair of wheels engages the second pair of wheels when the housings are in the closed position. The shell has openings on opposite ends thereof. A tube can extend through the openings and between the first and second pair of wheels so as to allow fluids therein to be flushed therefrom as the shell moves along the length of the tube.

Abstract: An integral, open-sided basin is formed with body supporting steps, a number of air jets and fittings for water circulation. The open side is connected to a corresponding opening in the wall of a swimming pool and the opening is selectively closed by a removable divider panel to allow the basin to serve as pool entry or exit, a therapy pool at the side of the swimming pool, or, when connected to another identical therapy basin, to serve as a totally independent and self-contained therapy pool.
