Abstract
Abstract A system is disclosed which provides for lavaging the lower intestinal tract of a patient by the use of an instrument that is adapted to be inserted into the anal canal of a patient. The instrument is provided with an inlet passageway and an outlet passageway. Auxiliary apparatus is provided for controlling the supply of water flowing by way of inlet tubing into the inlet passageway of the instrument so that the water is introduced into the lower intestine with a negligible amount of force in order to insure the safety and comfort of the patient. Furthermore, discharge tubing on the outlet passageway of the instrument is held at a predetermined height by a water-level-regulator so that the inflowing water can be retained to penetrate the lower intestine at a desired height.
