Figure 6 is a front perspective view of the device of Figures 1 through 5, Figure 7 is a front oral view of a person showing the device fitted in use with its protuberant region extending backwa is over the tongue to stop the tongue from falling back and blocking the airway passage when the user's mouth is closed, and

Figure 8 is a lateral section of such a user showing the protuberance extending rearwardly to protrude down from within the range of from 2mm to 20mm from the appliance body proper projecting downwardly from mat region of the body portion which is just in front of the soft palette.

BESTMODE(S)FORCARRYINGOUTTHEINVENTION

In the preferred form of the present invention the device is ideally as depicted in the accompanying drawings having preferably been formed as follows: the top section is vacuum formed from a dental stone prepared from an alginate impression of a user's top teeth and gums. An area is measured from the last tooth on either the right or left upper side to the faraway point of the rearward top section of the tongue with the tongue fully relaxed. This is done by holding a wooden spatula with downward pressure on the tongue. The top section is preferably vacuum formed polyethylene so as to hold the fabricated device firmly in place through suction, somewhat in the manner of a mouthguard therefor, the top section of body section proper 1 can be carried by the top teeth of a user.

Formed integrally with the polyethylene to be vacuum formed to conform to a users teeth or fabricated to the device is a downward depressor 2 designed to hold the bottom lip apart from the top lip of a user thus enabling the user to inhale without obstruction through the mouth. A pair of spacers 3 preferably to be positioned between the canine and the last molar keeps the top and bottom teeth separated by approximately 4 to 10mm which enables a clearer air passage between lips and the soft pallet.

A protuberant region 4 preferably fabricated by appropriate moulding, welding or the like to the formed polyethylene top section is of polyethylene preferably having been formed from two polyethylene straps joined together. The upper end region of the protuberant member 4 is joined to the hard pallet area of the upper section 1 at 5 and in some forms of the present invention irrespective of whether or not adhesive moulding or welding is utilised some mechanical interengagement of the components to be fabricated can be provided and other forms of the present invention a range of premoulded components may be provided which requires only the vacuum forming of an upper region where other aspects of the device are determined as being a proper fit for a potential user.

The preferred form however has the protuberant member fabricated separately and associated with the device after conforming thereof to the teeth of the user and the provision thereof (if they are not already integral) of this spacing members 2 and 3.

The narrower (lower) end of the protuberance preferably defines tongue resting pad 7 which is preferably substantially rectangular. The area of this pad depends entirely on the size of the tongue.

In the preferred form of the present invention the polyethylene straps are heated and manipulated to exact measurements which causes the pad to rest on an area between the long filiform and the foramen caecum positions on the tongue. The tongue is held in a fully relaxed downward position.

In the preferred form the protuberant member 4 and/or the straps thereof are to be kept as thin as possible to prevent airway restriction.

In use therefor a user as shown in Figure 8 can close his or her lower teeth up onto the device but still have an established airway passage and the device with its protuberant member preferably extending from 2mm to a maximum of 20mm down from the section 1, ie. the distance X is preferably within the range of 2mm to 20mm.

By stopping the tongue from retracting into the oropharynx which causes an airway blockage between the soft pallet the tongue and the oropharynx an established air passage exists once the device has been worn.

Without the device, even where there is no blockage, air forced between the soft pallet, the tongue and the oropharynx with many people causes the soft pallet incorporating the uvula to vibrate on inward inhalation of air and to vibrate also on exhalation, thus providing what is commonly referred to as snoring.

The present invention therefor envisages a device capable of being readily fabricated using premoulded components or of being fitted with one or more premoulded components.
