<p>A gravity supplied irrigator for colon cleansing has an open ended nozzle with the inner end tapered to accommodate a removable rounded nose obturator extending from the inner end with the body of the rounded nose obturator bearing against the inner surface of the inner end. A gravity actuated fluid supply to the irrigator is provided by a conduit leading into the nozzle intermediate of its ends and the obturator is removable through the nozzle in order for the fluid supply to enter the irrigator. The conduit supply is preferably offset in relation to the longitudinal axis of the nozzle to provide a swirling action to the entering fluid. The nozzle has an outwardly extending circumferential flange intermediate of the inner end and the conduit, which flange limits the insertion of the irrigator. A conduit attached to the other end of the nozzle has variable control means thereon to control the pressure of fluid in the nozzle and its rate of discharge from said nozzle.</p> |
