Abstract: An oral delivery device for delivering substance directly into a mouth of a patient includes an elongated flexible conduit coupled to a connector at a proximal end thereof for connecting to a substance source, and a nipple portion at an opposing distal end thereof for placement into a mouth of a patient. The nipple portion defines a flow aperture at a distal tip thereof. The distal end of the flexible conduit is located substantially immediately adjacent to, and in sealed fluid communication with, the flow aperture, such that substance exiting the distal end of the conduit substantially directly exits the nipple portion through the flow aperture and enters into the mouth of the patient.
