Patent ID: 7294120

Claim:
An automated instillation apparatus for instilling fluid into a client having an intestinal stoma thereby administering an antegrade colonic enema comprising; a fluid reservoir being a sealable and collapsible container, a pump assembly having an inlet and an outlet, said pump assembly inlet in direct fluid communication with said fluid reservoir, said pump assembly produces a fluid flow when activated, having a gear type pump and an electric pump motor, a reverse flow prevention means for limiting said fluid flow to a direction from said pump assembly inlet to said pump assembly outlet, said reverse flow prevention means in fluid communication with said pump assembly, the reverse flow prevention means being a pressure release valve in fluid communication with said pump assembly only when a fluid pressure at said pressure release valve inlet is greater than a fluid pressure at said pressure release valve outlet by a predetermined amount of fluid pressure for preventing reverse leakage of fluid when said pump assembly is not activated, a fluid delivery line having an inlet and an outlet, said fluid delivery line inlet in direct fluid communication with said pump assembly, an intestinal stoma catheter detachably connected to said fluid delivery line outlet wherein said intestinal stoma catheter is inserted into stoma opening to the large intestine of a client to be injected with fluid for purposes of administering an antegrade colonic enema, a pump control module communicatively connected to said pump assembly, said pump control module operable to signal said pump assembly to transfer a predetermined volume of fluid by providing said pump assembly with power while measuring a current consumption of said pump motor, until said current consumption increases to a predetermined amount resulting from said electric pump motor current increase when said fluid reservoir is empty and collapsed thereby creating an increased load on the pump, whereby an automatic shutoff is effected, and a portable power source electrically connected to said pump control module.
