with reference to the drawings wherein like numerals represent like parts throughout the figures , a mouthpiece module , in accordance with the present disclosure , is generally designated by the numeral 10 . the mouthpiece module functions in conjunction with a nasal mask 12 for a cpap machine 14 to prevent air leakage from the mouth while a user is using a cpap machine . the nasal mask 12 can take many forms , and nasal mask 12 is intended to be representative of any of the various forms which can be employed . the mouthpiece module 10 is manufactured from a flexible absorbent cloth or textile material . the mouthpiece module is configured and dimensioned to rest between the lips of the user , as best represented in fig2 , and does not extend beyond the teeth . the preferred cloth or textile material for the mouthpiece module is preferably cotton , but may be polyester . bamboo , fleece , fabric , hemp or elastic or other flexible absorbent materials may be employed . the preferred length of the mouthpiece module is 30 - 40 inches . naturally , the mouthpiece module is healthful , clean and safe . the mouthpiece module 10 comprises a rectangular , quasi - rectangular , oval or generally elongated mouthpiece 20 . the mouthpiece has a top edge 22 , an opposed second edge 24 and opposed ends 26 and 28 . the mouthpiece has a length which exceeds the length of the lip interface of the user when the lips are closed . the preferred dimensions of the mouthpiece 20 are 1 - 3 inches in width and 3 - 5 inches in length . a pair of straps 30 and 40 extend from a medial location of the opposed ends 26 and 28 . in one embodiment , the straps 30 and 40 each have a length which is more than sufficient to extend around the head of the user and to provide sufficient end material for comfortably tying the straps in a knot at the back of the head of a user . the preferred width of the straps 30 and 40 is ¼ - ½ inch . the straps 30 and 40 are non - irritating and comfortable . the ends of the straps may alternatively be secured by a pin , clasp or various fasteners or , in some embodiments , even by an elastic connector or hook - and - loop fabric ( velcro ™) fastener . in addition , as best illustrated in fig2 , the upper and lower flexible panel portions 50 and 60 of the mouthpiece 20 engage around the upper and lower lips of the user in a reverse fold fashion , as best illustrated in fig3 . in some embodiments , the straps may be stitched to the ends of the mouthpiece 20 . in other embodiments , the straps may simply integrally extend from the mouthpiece . in another embodiment , the straps may also be a single continuous elastic band , stitched or integral to the mouthpiece 20 . any of the above securing means are suitable for securing the straps at the back of the head so that the mouthpiece is firmly secured in the mouth . once the mouthpiece 20 is properly positioned and retained in place to the user , it will be appreciated that the mouthpiece provides a flexible comfortable structure which prevents airflow from the mouth . in addition , the absorbent material from the mouthpiece will absorb any moisture in the oral cavity which impinges in the lip area . with reference to fig5 , another embodiment of a mouthpiece module is generally designated by the numeral 100 . mouthpiece module 100 comprises a rectangular or quasi - rectangular elongated mouthpiece 120 . the mouthpiece module 100 is especially adapted so that the mouthpiece 120 may be dismounted and replaced by another or a new mouthpiece as required . in this regard , the mouthpiece may be replaceable or , in some cases , disposable . the mouthpiece 120 has a top edge 122 , an opposed second edge 124 and opposed ends 126 and 128 . it should be appreciated that , depending on the mouthpiece geometry , the edges and ends may not have a well - defined point of demarcation . the mouthpiece 120 has a length l 2 ( which exceeds the length of the lip interface of the user when the lips are closed ) and has a width w 1 . a pair of connectors or tab - like appendages 150 and 160 extend from a medial portion of the ends 126 and 128 , respectively . the appendages may be integral with the mouthpiece , stitched or otherwise connected . the opposite ends of the appendages mount a fastener , such as a portion of a hook - and - loop or velcro ™- type fabric fastener 152 and 162 , respectively . the length of each fastener is designated by the length l 3 . straps 130 and 140 which , in one embodiment , are preferably separate segments , each include a mating fastener , such as a second velcro ™ fastener , hook - and - loop fabric , or velcro ™- type fastener portion 132 and 142 which connect with the fastener portions 152 and 162 , respectively , in overlapping relationship . the straps 130 and 140 are preferably substantially identical and have a width designated as w 2 . when the straps are connected to the appendages 150 and 160 , the maximum longitudinal distance between the free ends of the straps is designated by l 1 . the length l 1 is sufficient that the straps may be either tied or otherwise connected at the back of the head of the user . the straps may include various mechanical fasteners for fastening the straps at the back of the head of the user . the preferred maximum dimension l 1 is between 30 and 40 inches . in one embodiment , the straps may essentially be connected end - to - end at ends 135 and 145 or seamlessly joined so that components 130 and 140 are essentially strap segments of continuous band and the strap has sufficient elasticity so that it can be wrapped around the back of the head of the user and be sufficiently taut to mount the mouthpiece module in a proper taut installed position , such as illustrated in fig2 . table 1 set forth below illustrates representative samples for various different dimensioned embodiments of mouthpiece module 100 . the fasteners are connected to the straps 130 and 140 so that the proximal end of the straps include a tab 134 and 144 to allow for easy removal or disconnection of the straps from the tab appendages . with reference to fig6 , the mouthpiece module 200 is configured to attach around the ears of the user to mount the mouthpiece 120 in position as previously described . straps 230 and 240 are preferably identical and respectively mount an elastic loop 232 and 242 . each loop is dimensioned and configured so that they loop around the ears of the user . the elastic loops 232 and 242 are preferably formed from thin elastic and attached to fastener portions 252 and 262 . the mouthpiece 120 may be similar in form and function to that described for the mouthpiece of fig5 . while preferred embodiments of the foregoing have been set for purposes of illustration , the foregoing description should not be deemed a limitation of the invention herein . accordingly , various modifications , adaptations and alternatives may occur to one skilled in the art without departing from the spirit and the scope of the present invention .
a new innovative and unique solution to minimize the problems of mouth leakage using a cpap machine is disclosed . a mouthpiece module is specifically designed to solve the problem of mouth leakage which compromises the therapeutic effect of cpap treatment . the mouthpiece module comprises a flexible absorbent material which partially wraps around the lips and is secured to the back of the head by straps or an elastic band . in one embodiment , the mouthpiece is detachable from a securement strap .
