Antegrade colonic instillation apparatus

An instillation apparatus for the purpose of pumping fluid into the intestinal tract through a stoma opening as presented by a patient, comprising,

• a fluid reservoir having a housing, a top and a bottom suitable for holding instillation fluid, the bottom being a bulkhead plate,
• an internal component chamber having housing, a top and a bottom wherein the chamber top is the bulkhead plate of the fluid reservoir, the bottom having a base with a cavity for holding a battery power supply,
• a pump assembly having an electric pump motor, drive transfer and pump manifold with the pump manifold having a pump cavity, an inlet and an outlet, mounted from below through an opening in bottom of the fluid reservoir and inside the internal component chamber with the inlet in direct fluid communication with the fluid reservoir and the outlet protruding upwardly into the fluid reservoir but not in fluid communication with the reservoir,
• a delivery tube being flexible and having a proximate and distal end with the proximate end in direct fluid communication with the pump manifold outlet,
• a catheter suitable for insertion into a patient with an intestinal stoma constructed for purposes of instilling fluid into a patient's intestines in direct fluid communication and removably attached to the distal end of the delivery tube,
• a pump control module communicatively attached to the pump motor for purposes of activation, and mounted in the internal component chamber,
• a fluid recess chamber being formed as an expansion of the pump manifold inlet having a top, height, wall, bottom, filter in the top in direct fluid communication with the fluid reservoir, and a draw tube positioned vertically and a top end positioned near and below the filter and having a drain hole tangent to the bottom of the recess chamber with the draw tube in direct fluid communication with the pump cavity,
• a fluid level sensor mounted in the fluid recess chamber wall operable to communicate the presence of fluid in the chamber to the pump control module to which it is communicatively attached, the pump control module further being in direct electrical communication with the battery power supply;
• and,
• a user control panel mounted proximate to the internal component chamber being in direct electrical communication with the pump control module.
