An oral appliance for administering a stimulus, such as a substance, to the mouth of a user includes a flexible tube having an inlet portion, a first curved portion forming an ear loop connected to the inlet portion, a second curved portion forming a lip bend connected to the first curved portion, and an outlet portion extending from the second curved portion. Alternatively, a mouthpiece for delivering a substance to the mouth of a user includes a housing having an inlet portion, a riser portion extending upwardly from the inlet portion and a curved outlet portion. A flexible tube is coupled to the housing. A method of delivering a substance to a predetermined location in a user's mouth includes disposing a flexible tube between a row of teeth and an interior surface of a cheek. The flexible tube has an exit port positioned in a rear portion of the user's mouth. No portion of the flexible tube is disposed between the upper and lower teeth of the user such that the upper and lower teeth can be closed against each other. The method further includes dispensing a substance through the exit port.

An oral appliance for use with a subject in his/her mouth includes a flexible tube having an input end and an output end and an electrode coupled to the flexible tube adjacent the output end. The flexible tube is adapted to be positioned in the subject's oral cavity with the output end positioned in a posterior region of the oral cavity. The electrode is adapted and configured to administer an electrical stimulation to the posterior region of the oral cavity. An electrode lead is disposed within the flexible tube and connected to the electrode. An electrical stimulation control unit is connected to the electrode lead. A method of administering an electrical stimulation to a posterior region of an oral cavity of a subject is also provided.

The present invention relates generally to an oral device, or mouthpiece, for delivering a fluid to the mouth or oropharynx of a user. In one embodiment, the oral device includes an intraoral portion, an extraoral portion, and an auxiliary support device that serves to stabilize the oral device. In various embodiments, the auxiliary support device may be configured with ear loops, a support band, a support frame and/or a support member. The intraoral portion generally includes at least one outlet port through which the fluid is delivered to the oral cavity or oropharynx. A method of dispensing a fluid using the oral device is also provided.

A pill swallowing device comprising a deformable reservoir for holding an edible liquid; a liquid refilling port attached to the deformable reservoir; a pill transit port for loading and discharging pills attached to the deformable reservoir; and a cap detachably connected to the pill transit port, the cap comprising a pill-positioning insert that engages the pill, that projects into the deformable reservoir for directing the pill inside the reservoir.
