Abstract: A bathtub which can be inflated about a bed-ridden patient with minimum inconvenience to the patient is disclosed. Inflatable tubular cells form the sidewalls which support an impermeable liner forming an enclosure. A cover extends between the sidewalls. Conduits for water supply and drainage communicate with the enclosure. The supply system includes a spray system to direct water against the prone patient. An independent water recirculation system and thermostatically controlled heater may also be incorporated.
