ABSTRACT:
Colon washing apparatus and methods wherein water flow to the colon may be by gravity flow or by pumped flow, wherein temperature control of the wash water is controlled by mixing of hot and cold water or by means of a water heater means, wherein wash water pressure is controlled by water head or by pump output pressure, and by pressure flow valve controls, wherein pulsating water flow may be used, wherein oxygen may be introduced into the wash water, wherein water penetration into the colon may be assisted by abdominal massage, wherein the nozzle may be introduced through the colon by water jet action, and wherein angular water jets from the nozzle may cause washing action ahead of the nozzle. The apparatus is fail-safe in that alternative modes of operation are available in case of power failure. The patient can control the apparatus in case of operator absence or patient discomfort.
