Abstract

An apparatus and method for providing a colonic lavage to a patient comprises a speculum for insertion into the colon of the patient with the speculum being generally tubular and having a tapered end within the colon with opposing openings formed therein and discharge and inlet openings outside the anal canal. The inlet opening is connected to a lavage liquid holding chamber through an inlet conduit and the discharge conduit is connected to a collection chamber through a discharge conduit. The discharge conduit has a resilient collapsible portion that passes through a pinch valve that can be actuated to close the discharge conduit. In operation, lavage liquid is pumped from the holding chamber while the pinch valve is closed causing the colon to fill with liquid. When the colon is full, pumping is discontinued and the pinch valve opened allowing liquid and loosened fecal matter within the colon to be purged through the discharge conduit to the collection chamber.
