Abstract:
A feeding and aspirating device comprising:a unitary elongate tube having a tube wall defining a central lumen, the tube having a distal end portion for placement within a patient's digestive system, a proximal end for placement exterior to the patient and a central portion of predetermined length, the central portion having an aspirating zone extending over a segment of the central portion proximate to the distal end portion, the aspirating zone having at least two openings between the central lumen and an area exterior to the tube, a first of the two openings at a first longitudinal distance from the distal end portion and a second of the two openings at a second longitudinal distance from the distal end portion, the second distance different than the first distance; and a feeding orifice in the distal end portion for communication between the central lumen and a feeding area exterior to the tube, the feeding orifice having a one way valve allowing a solution to pass through the tube and exit the feeding orifice and preventing substantially any flow into the central lumen through the feeding orifice.
