ABSTRACT:
A rectal speculum assembly for use with a colonic lavage machine includes a speculum and an obturator. The speculum includes an unobstructed main tube for directing fluids into and out of a patient's rectum, and an inlet tube for injecting treatment fluid into the main tube. The inlet tube intersects the main tube, forming an obtuse angle with respect to the proximal end of the main tube, so that inlet fluids are initially directed away from the patient's rectum, and thus do not interfere with fluided waste matter being discharged therefrom. In addition, a thumb rest is provided on the main body of the speculum for holding the speculum steady while the obturator is removed and a waste removal hose is connected.
