Definitions

  • the invention relates to a device to assist breathing and to a method of preparing the device for use.
  • the invention is directed particularly but not solely towards a device that can be inserted into a mouth to alleviate snoring or sleep apnoea.
  • Breathing can involve snoring and sleep apnoea which are problems that have been around for as long as there have been people on earth. Both snoring and sleep apnoea problems can result from relaxation, during sleep of two muscles associated with the airway ie the tongue and the lower jaw muscle. As these muscles relax the back of the tongue falls back and partially or completely blocks the airway. Because the tongue is attached to the lower jaw, a reduction in snoring can be achieved by forcefully preventing one or the other from falling back, but this is very difficult to do simultaneously and independently.
  • Snoring is not just a problem for the sufferer who may experience disrupted sleep but for any sleeping companion(s) either in the same bed or in the same room.
  • sleep apnoea which can also be disruptive for the patient and companion(s), can lead to disrupted breathing possibly leading to death in some cases.
  • the invention resides in a device to assist breathing for a mouth including upper and lower teeth and upper and lower jaws forming an airway there between, the device includes a central body with outwardly splayed wing members, whereby in use the central body and wing members have an upper surface and lower surface, a front end rear end with edges wherein at least a portion of the lower surface of the central body has at least a roughened portion thereon, wherein in use the device, itself being held in place in the mouth by engagement of the upper side of the wing members with the upper teeth, which in turn holds the tongue in position via the engagement of at least a portion of the roughened portion of the lower surface of the central body with at least a portion of an upper surface of the tongue, while at the same time the device holds the lower jaw in place via the engagement of the lower side of the wing members with the lower teeth.
  • gripping the tongue prevents the tongue from falling back and blocking the airway when the user is asleep while the tongue is relaxed, while at the same time the wing members are gripped by the upper and lower teeth.
  • engagement of the wing members of the lower teeth into a lower section of the device prevents the lower jaw from falling back.
  • Preferably engagement by the upper teeth and lower teeth to the wing members includes gripping the wing members.
  • the gripping includes gripping the wing members whereby the teeth intermesh with complementary depressions formed in each wing member.
  • the central body is a channel shaped body including a square shaped cross sectional shape and includes a base and side walls.
  • At least one wing cap member encases or covers at least a portion of each wing member and are planar in shape being oriented parallel to the wing member.
  • the device is formed of a thermoplastics material wherein the channel shaped body is formed from a high melting point thermoplastics material and the wing members or cap members are formed from a low melting point thermoplastics material.
  • the side walls of the channel shaped body are substantially vertical having a sloping top end edge.
  • the front end edge includes a front end edge of the wing members and/or wing cap member are rounded in a horizontal plane.
  • front end edge includes a front edge of the side wall being rounded in a vertical plane.
  • the rear end edge of the wing cap members are rounded in the horizontal plane whereas the rear end edge of the channel shaped body and wing member are straight.
  • the device has a greater length dimension from side to side than front to rear.
  • the wing cap members are positioned on the wing members to extend rearwardly beyond an end edge of the wing members, be recessed from a front end edge of the front end edge of the channel shaped body and extend beyond a side end edge of the wing members whereby there is a gap between the side of wing cap member and side wall of the channel shaped body.
  • the invention resides in a method of preparing a device for use, the device to assist breathing for a mouth including upper and lower teeth and upper and lower jaws forming an airway there between, the device includes a central body with outwardly splayed wing members, whereby in use the central body and wing members have an upper surface and lower surface, a front end rear end with edges wherein at least a portion of the lower surface of the central body has at least a roughened portion thereon, wherein in use the device, itself being held in place in the mouth by engagement of the upper side of the wing members with the upper teeth, which in turn holds the tongue in position via the engagement of at least a portion of the roughened portion of the lower surface of the central body with at least a portion of an upper surface of the tongue, while at the same time the device holds the lower jaw in place via the engagement of the lower side of the wing members with the lower teeth, wherein the wing members are formed from a low melting point thermoplastics material wherein the method includes the following steps
  • the device should be centralized on the lower teeth side to side and slid forward as far as it will go into the mouth;
  • Figure 1 is a perspective view in accordance with a first preferred embodiment of the invention.
  • Figure 2 is a top plan view with regard to figure 1
  • Figure 3 is a side view with regard to figure 1
  • Figure 4 is a front end view with regard to figure 1
  • Figure 5 is perspective view of another embodiment of the invention.
  • Figure 6 is top plan view with regard to figure 5
  • Figure 7 is a side view with regard to figure 5
  • Figure 8 is a front end view with regard to figure 5
  • device 1 is an intra oral device which is useful in assisting with breathing or alleviating or reducing snoring and/or sleep apnoea.
  • the device 1 is adapted for use in a mouth having upper and lower teeth or teeth and upper and lower jaws or jaws forming an airway therebetween.
  • the device 1 is shaped from a planar material having a central body 3 of any shape that allows contact with the tongue, like for example a semi circle or shaped as a channel shaped body comprising a base 4 and side walls 5, with wing members 7, 8 extending substantially horizontally outwardly on each side at a top edge 9 of side walls 5, away from central body 3.
  • the channel shaped body 3 assists in stiffening the body so that gentle pressure that is needed for the roughened portion 20 to grip the tongue does not bend channel shaped body 3 out of shape. Additionally the channel shaped body lowers the roughened portion 20 with respect to the teeth so as to not require the tongue to be pushed forward too much, to allow gripping to take place without discomfort though this depends on each particular mouth shape and structure. What is unique is the way in which the invention is able to control the tongue. Additionally the invention is able to simultaneously and independently control the lower jaw.
  • Lower surface 15 of the channel shaped body 3 has at least a portion of that surface 15, with protrusions or roughness or roughened portion 20 which can be for example in the form of small spikes.
  • Side walls 5 can be the same height from front to rear/back or can be a different height at the front to the rear causing there to be a sloping top edge 9 from front (or rear) to rear (or front).
  • Wing members 7, 8 can be horizontal or angled to any desire orientation with respect to side walls 5 and can be shaped in any suitable shape in plan such as rectangular or trapezoidal with rounded or angled corners. Wing members 7, 8 can have suitable roughness on any of its surfaces and can be covered with a suitable covering if required.
  • Winged cap members 22 and 23 are formed as bulbous type formations or covers on at least a portion of wing members 7 & 8 and in use are designed to be gripped by the teeth in the mouth. In another option the wing members 7 & 8 themselves can be gripped the teeth.
  • Front end edge 10 of the device 1 includes a front edge in a horizontal plane for channel shaped member 3 being straight, front edge of wing members 7, 8 being rounded from a point at the top end edge 9 of side walls 5 and front edge of wing caps 22, 23 being rounded.
  • Rear edge 11 of the device has the rear edge of the channel shaped member 3 and wing members 7, 8 being level or straight and wing caps 22, 23 being rounded in a horizontal plane.
  • the front edge of side walls 5 is upwardly curved in a vertical plane.
  • the rear end edge vertically for the channel shaped member 3, wing members 7, 8 and wing cap members 22, 23 are level with each other being substantially vertical in a vertical plane.
  • the area of the wing cap members 22, 23 can be larger than the area of the wing members 7, 8 or be such that they extend rearwardly beyond an end edge of wing members 7, 8 but be recessed back from the front end edge 10 of the wing members 7, 8 and extend laterally beyond a side edge of wing members 7, 8. Also as shown the side edge of the wing cap members are spaced by a gap 24 from an outer surface of the side walls 5 of the channel shaped member 3.
  • front end 10 (as in use) is curved and the roughened portion 20 faces outwardly of the channel shaped body 3 and downwardly (when in use) to abut and intermesh and grip with an upper surface of the tongue.
  • the wing cap members 22, 23 are rounded being recessed back in the front from the front end edge 10 of the channel shaped member and extend rearwardly beyond the rear end edge 11.
  • Front end edge 10 can be rounded or curved 25 in a vertical plane.
  • Wing members 7, 8 and wing cap members 22, 23 need to be shaped or comprise at least a part of, of a material that allows them at least, to be able to be deformed by biting or pressing down when being prepared for use (see method), to form depressions that match exactly or be similar or close to the shape of at least an end portion of the teeth and to remain deformed during normal use of the device 1.
  • device 1 is an intra oral device which can be for example injection moulded from one melting point like for example a low melting point thermoplastics material to allow moulding by user with hot water and bending or alternatively the device can include parts of the device 1 formed of different melting points.
  • the channel shaped central body 3 with or without the wing members 7 & 8 can be formed of a high melting point thermoplastics material and the wing cap members 22 & 23 can be formed of a low melting point thermoplastics material.
  • Wing cap members 22 and 23 can be as large or as small and shaped as required or can simply be formed integrally as part of the wing members 7 and 8 whereby the wing members themselves perform this function but the wing cap members 22, 23 and/or wing members 7 and 8, must be malleable or soft enough to allow biting thereon by teeth, to hold the device 1 in place in the mouth.
  • each wing cap member can be planar in overall shape similar to each wing member but of the same shape or not and are planar in shape being oriented parallel to each wing member which also can be planar in shape.
  • the planar shape of the wing cap members or wing members can include a substantial horizontal plane parallel with the overall planar shape having a width or length being less than a thickness or vertical depth.
  • the device 1 When in use the device 1 itself, is held in place in the mouth by engagement of the upper side of the wing members or wing cap members with the upper teeth, which in turn holds the tongue in position via the engagement of the roughened portion of the lower surface of the central body with an upper surface of the tongue, while at the same time the device holds the lower jaw in place via the engagement of the lower side of the wing members with the lower teeth.
  • the engagement by the upper teeth and lower teeth includes gripping whereby the teeth intermesh with complementary depressions in the wing member which are formed when the device is prepared for use as given by the method disclosed in this specification.
  • Gripping the tongue is to prevent the tongue from falling back and blocking the airway when the user is asleep while the tongue is relaxed while at the same time the wing members are gripped by the upper and lower teeth.
  • initially device 1 can be moulded in a flat form and the user then warms the device in hot water to a point where it can be folded over, bending naturally at the narrowed hinge section, then insert into the mouth and bitten down on to, to from the semi-circular wings into the shape of the users back teeth with the lower jaw in the position in which the jaws naturally close together. That is, there is no need to pull the lower jaw forward into a position which would become uncomfortable after a while.
  • a plate with hundreds of tiny, forward leaning spikes on the surface is attached to the device via small studs which are part of the plate moulding.
  • the studs are an interference fit in the corresponding holes in the device, so as the device cools it grips the plate studs firmly.
  • the plate is injection moulded in a fairly hard (Shore D) high melt temperature thermoplastics material.
  • the spikes on the plate engage with the naturally rough surface of the top of the tongue to grip the tongue and prevent it from falling back and blocking the airway when the user is asleep and the tongue is relaxed.
  • the engagement of the lower teeth into the lower section of the device prevents the lower jaw from falling back.
  • An adjustable elastic chin strap can be included in the pack for those users whose upper and lower jaws tend to fall open while sleeping.
  • the device should be centralized on the lower teeth side to side and slid forward as far as it will go into the mouth;
  • boiling device 1 again will reform the wing cap members 22, 23 back to their original shape.
  • Some users of the device 1 may notice an increase in saliva production which is normal and will settle down very quickly as the mouth gets used to having the device 1 there.
  • the upper and lower teeth might also grip the wing members 7, 8 or wing cap members 22, 23.
  • these depressions can be formed during boiling as in the above method but can also be formed when the wing members or wing cap member are softened by heat or even just by biting. Alternatively the engagement can just be by gripping without the depressions.
  • An adjustable elastic chin strap can be included in the pack for those users whose jaws tend to fall open while sleeping.
  • ADVANTAGES a) Able to simultaneously and independently control both the tongue and the lower jaw a) Minimal discomfort through us of the device b) Able to be used to not cause discomfort or injury c) Direct control of the tongue d) Simultaneously and independently control the lower jaw e) Improves sleeping and/or breathing f) Simple manufacture g) Modest cost h) Easy to use i) Able to be reused j) Simple method for preparing for use
  • Device 1 can be formed from any suitable material able moulded to fit a mouth or be a material able to be repeatably heated and deformed such as regular polypropylene for the body 3 and a propylene-based elastomer (PBE) like for example VistamaxxTM for the wing members 7, 8 and or wing cap member 22, 23.
