Abstract:

A colonic irrigation apparatus for cleaning bodily orifices such as the large intestine, which converts pressurized water from a building's water supply into a gravity flow and which provides precise temperature control even at extremely low flow rates. Water temperature is regulated by alternating the flow from separate hot and cold water inlets around a preset temperature set point, and sending the water into a filter. The filter blends the water, evening the temperature, whereupon the water passes through a temperature safety valve and on to an elevated pressure-to-gravity converter. Pressure is regulated by the converter, which receives the pressurized water, drains most of it under the flow of gravity to the patient at a preset flow rate, and vents the excess pressure by diverting a variable flow of the incoming water down to a drain.
