Abstract

An oral weight control apparatus and method adapted to block solid foods from entering the stomach of a user thereof, while at the same time allowing the user to freely move his tongue and jaws, to talk, to breathe, to drink fluids, and to participate in other desirable activities without the presence of the apparatus being visible or otherwise made known to anyone other than the user. The apparatus includes a guard, net, or other sieve-like blocking means that is secured inside the mouth of the user. Liquids and finely ground foods may freely pass through the guard or sieve but solid foods may not. In the preferred embodiment, the blocking means functions as a one-way valve, blocking solid foods from entering the stomach through the mouth but allowing food within the stomach to pass back out through the mouth (as would occur, for example, during regurgitation). The method includes mounting such an apparatus within the mouth in order to constrain the user to follow a suitable diet comprised of liquids and finely ground foods having a desired nutrient level.

Claims

1. An oral weight control device for impeding the eating process and slowing down the rate of food consumption to thereby allow the body time to naturally register the sensation of being full prior to completion of a meal, said device comprising:

an upper support member adapted to be secured to the inside back of the user'"'"'s mouth;

a sieve-like guard pivotally coupled in vertical orientation to the support member to allow the guard to raise and lower in response to movements of the user'"'"'s tongue, said guard having meshed openings therein of a selected size to impede the otherwise unobstructed passage of large food particles;

said guard including means for positioning a bottom edge thereof at a part of the mouth forward of the support means and near the user'"'"'s tongue when the device is properly located within the mouth;

said pivotal attachment providing means for displacement of the guard into a substantially nonblocking position in response to emergent food, thereby preventing possible choking from regurgitated food material.

2. An oral weight control device as defined in claim 1 wherein said guard comprises a lattice of relatively stiff wires bonded to each other in a pattern that realizes the desired meshed openings.

3. An oral weight control device as defined in claim 2 wherein said wires are further bonded in a shape that approximates the inside contour of the user'"'"'s upper mouth.

4. An oral weight control device as defined in claim 1 further including spring bias means for maintaining said guard in its closed position at all times regardless of the orientation of the user'"'"'s mouth with respect to a gravitational force field, said spring bias means allowing said guard to assume its open position only in response to a rearward pressure placed thereupon having a force greater than that of said spring bias means.

5. An oral weight control device as defined in claim 1 wherein said food blocking means is detachably secured to the inside of the user'"'"'s mouth, said detachable securement being realizable only with the aid of another person, such as an oral surgeon or dentist.

6. A method for impeding the eating process and slowing down the rate of food consumption to thereby allow the body time to naturally register the sensation of having hunger satisfied prior to completion of a meal, said method comprising the steps of:

securing a food blocking device to the teeth inside the mouth of a user without interference to jaw movement, said device being adapted to impede ingesting unchewed solid foods taken into the mouth, yet being unobstructing to emergent foods from the stomach to permit substantially unimpeded passage thereof through the mouth in the event that said user has need to reguritate an amount of ingested food; and

retaining the device within the mouth for sufficient time to result in loss of weight as part of a weight loss program.

7. A method for assisting a patient to lose weight by impeding the eating process and slowing down the rate of food consumption to thereby allow the body time to naturally register the sensation of having hunger satisfied prior to completion of a meal, said method comprising the securing of a food blocking device to the teeth inside the rear of a patient'"'"'s mouth without interference to jaw movement, said device being primarily adapted to impede the passage of unchewed solid foods through the mouth to the stomach, yet being nonobstructive to food emergent from the stomach to permit substantially unimpeded passage thereof through the mouth in the event said patient has need to regurgitate an amount of ingested food.

8. A method as defined in claim 7, wherein the food blocking device is secured to the upper rear teeth, thereby forcing the patient to more thoroughly masticate solid food particles by retaining food at the back teeth rather than allowing unobstructed flow of unchewed food into the stomach.
