ABSTRACT:
A portable apparatus (51) for delivering a colonic lavage to a patient includes a portable frame (52) preferably constructed of tubing, a lavage liquid reservoir (71) and a waste reservoir (72) both stowable in the frame (52), a speculum (78) for delivering the lavage liquid to the interior of a colon and for receiving waste from the colon, a waste conduit (88) communicating at one end with the speculum (78) and at another end with the waste reservoir (72), and a first sphincter valve (87) selectively opening and closing the waste conduit (88). A pump (66) housed in the frame (52) delivers the lavage liquid from an interior cavity of the frame (52) to the speculum (78) via a delivery conduit (91) coupling the speculum (78) with a pump tube (102) communicating with the pump (66). A regulator valve assembly (58) communicates with the pump tube (102) and ensures that the lavage liquid is never delivered to the colon above a predetermined pressure. A second sphincter valve (92) selectively opens and closes the delivery conduit (91) responsive to a controller (64), which may operate according to a predetermined schedule to deliver a pulsed supply of lavage liquid to the colon for dislodging impacted fecal material therefrom. The controller (64), operatively connected to both the first sphincter valve (87) and the second sphincter valve (92), effects the closing of waste conduit (88) during delivery of the lavage liquid, as well as the closing of the delivery conduit (91) during removal of waste from the colon.
