Definitions
- the present invention relates to a device and method for preventing or reducing the passage of air through the mouth.
- the invention has particular application in the fields of non-invasive nasal mechanical ventilation and nasal CPAP (continuous positive airway pressure) treatment.
- air or other breathable gas is supplied to a patient through a nose mask.
- the pressure of the supplied gas is varied during the breathing cycle.
- a pressure of around 4 to 20 cm H2O above atmospheric is generally used during expiration to splint open the upper airway and to improve gas exchange within the lungs.
- a pressure of around 0 to 40 cm H2O above the expiratory pressure is used to assist or replace the patient's own ventilatory efforts.
- Nasal CPAP for example, for the treatment of obstructive sleep apnea, generally uses equal inspiratory and expiratory pressures.
- a problem experienced by patients undergoing non invasive nasal mechanical ventilation or nasal CPAP treatment is that of air escaping (leaking) via the mouth. This leads to drying and dehydration of the nasal passages, reduction in the pressure of the treatment gas being delivered to the lungs, reduction in the amount of ventilatory assistance, and, where applicable, incorrect triggering or cycling of ventilatory assistance devices.
- FIGS. 1 and 2 show a mask 10 of this type being held in place by a strap 12. The mask 10 seals against the face 14 of the patient around the mouth, and the head strap 12 forces the mask 10 against the face 14 in the direction of arrows 16 to press and thereby seal the mask 10 against the face 14.
- a variation of the above arrangement involves replacing the resilient mask with a bubble or balloon-like membrane that is inflated by the gas being supplied to the patient.
- This mask conforms to the contours of the face more readily and thus allows the strap forces to be reduced.
- the invention provides a device for preventing or reducing the passage of air through the mouth, the device comprising a top lip member and a bottom lip member having a space therebetween, whereby said space is configured such that, in use, when the top and bottom lips of a wearer are forced through the space they are squeezed against the top and bottom lip members respectively to thereby substantially seal the mouth.
- the device is preferably resilient and squeezes the lips together in a supero-inferior direction to substantially seal the mouth.
- the device is preferably formed from a relatively stiff material and the gas pressure in the mouth behind the lips forces them against the respective lip members and against each other to substantially seal the mouth.
- the top and bottom lip members engage or grip the top and bottom lips respectively when the device is in use.
- top and bottom lip members are joined at at least one end. In another embodiment, the top and bottom lip members are joined at both ends thereby defining an aperture through which the lips are forced in use.
- the device is desirably shaped to conform to the shape of the lips. When viewed from above, the device is curved or crescent shaped. When viewed from the front, the device is substantially oval.
- the device can also desirably include a cover extending between the members.
- the cover provides a secondary seal for any air leaking past the lips.
- the cover can include a vent to reduce the likelihood of pressure build up behind the cover in the event of minor or intermittent air leaks past the lips.
- a preferred embodiment of the device includes a strap to assist in locating the device on the lips of the wearer.
- the device is manufactured from a malleable material and is shaped to conform to the wearer's face.
- the device may include a malleable component embedded therein or attached thereto.
- the malleable component can be a metal wire produced from, for example, aluminium, silver or steel.
- the device is manufactured from a heat formable material and is heated, shaped to conform to the wearer's face and then allowed to cool and set.
- the device may include a heat formable component embedded therein or attached thereto.
- the malleable component can be a plastics wire or ribbon.
- the device is preferable manufactured from a silicone rubber, for example,

- a first embodiment of a device 20 for preventing or reducing the passage of air through the mouth 22 of a wearer's head 24 The mouth includes a top lip 22T and a bottom lip 22B.
- the device 20 includes a top lip member 26 and a bottom lip member 28 which are formed from a resilient material.
- the resilient material can be, for example, a plastics material or a metal coated by a plastics material.
- the members are joined at ends 30 and 32 to define a space or aperture 34 therebetween. 25 When viewed from above (see Figure 5) the device is curved in the general shape of the lips 22T and 22B. Hooks 36 are also provided adjacent the ends 30 and 32 of the device 20 to allow it to be attached to a strap 38.
- the lips 22T and 22B are pursed together and squeezed through the aperture 34.
- the resilient top and bottom lips members 26 and 28 apply a compressive force to the lips 22T and 22B respectively, as indicated by arrows 40, to squeeze the lips together and thereby substantially seal the mouth.
- the region 42 adjacent where the top and bottom lip members 26 and 28 abut the lips 22T and 22B are compressed slightly and the regions 44 that are forced through the device expand to a slightly bulbous configuration as shown. This bulbous configuration assists in retaining the device 20 in place.
- the strap 38 is also used to retain the device in place and particularly to ensure the device is not dislodged during movement whilst the wearer is asleep. However, it is important to note that the strap does not necessarily have to apply a sealing force against the face or mouth.
- the upper and lower lips 22T and 22B are squeezed together in the direction indicated by arrows 40 in the supero-inferior (top-to-bottom) direction. This causes frictional forces to arise between the lips themselves and also between each lip and its respective lip member which primarily retains the device in place.
- the width A of the aperture 34 is determined so as to compress the lips 22T and 22B together in a sealing manner without discomfort.
- the width of the device 20 is determined such that the ends 30 and 32 of the device 20 lie against the skin 10 or 20 mm to the left and right sides of the mouth 20 in the postero- lateral direction.
- FIGS 8 to 11 show a second embodiment of the invention in which like reference numerals will be used to indicate like features.
- This second embodiment includes a cover 50 sealing the outermost edge of the aperture between the top and ' bottom lip members 26 and 28.
- any leakage of air past the lips that does occur is prevented from escaping to atmosphere by the seal 50.
- the primary sealing of the device 20 is due to the compressive force of the lip members 26 and 28 indicated by arrows 40.
- the forces in the direction of arrows 52 produced by the head strap generally only serve to retain the device in place.
- the supero-inferior seal of the device according to the invention can be supplemented by the antero-posterior seal provided by the regions 54 of the top and bottom lip members 26 and 28 abutting the face adjacent the mouth 22 by tightening the strap 38, in which case the forces in the direction of the arrows 52 become larger to provide the antero-posterior seal.
- Figures 12 to 15 show a third embodiment of the invention in which like reference numerals will be used to indicate like features.
- This third embodiment is a variation of the second embodiment and includes a high impedance vent 60 in the seal so that any small leaks past the supero-inferior seal of the lips do not cause a pressure build up behind the seal which might otherwise tend to dislodge the device 20. Also, in the event of a more severe failure of the supero-inferior seal, the antero-posterior seal, if utilized by tightening the straps, will provide an additional barrier to leak so that the leak is controlled to at most that which can pass through the vent 60.
- the device 20 includes a ribbon-like component 70 attached thereto.
- the component 70 is resilient and is bent or formed so as to be concave when viewed from the wearer to more closely comform the device 20 to the wearer's face.
- Metals such as aluminium, silver or steel are suitable for producing a resilient malleable component 70.
- Plastics are best suited for producing a resilient heat formable component 70.
- the component 70 also allows the width A of the aperture 34 between the top and bottom lip members 26 and 28 to be set at a predetermined fixed distance so as to provide a consistent lip sealing force.
- the component 70 can also include a vent 60 as described in relation to the third embodiment.
- Figures 19 to 21 and 22 to 24 show fifth and sixth embodiments of the present invention respectively which are similar to the first embodiment.
- malleable or heat formable components 72 and 74 are moulded within the top and bottom lip members 26 and 28.
- the components 72 are of circular cross section and in the sixth embodiment the components 74 are of flat ribbon-like cross section.
- the components 72 and 74 can be produced from the materials described in relation to the component 70 of the fourth embodiment.
- Figures 25 to 27 show a seventh embodiment of the present invention.
- the device 20 includes two substantially rigid steel wires 76 and 78 of 2 mm diameter embedded in the top and bottom lip members 26 and 28 respectively.
- the wires 76 and 78 are brass soldered together at ends 80 to join them together and form a loop.
- Two brass members 81 having external mushroom-shaped heads 82 are also soldered to the ends 80 to allow connection of the device 20 to a head strap (not shown) to assist in retaining the device 20 adjacent the lips of the wearer.
- the device 20 is positioned against the wearer's lip 22T and 22B by the neck strap which applies a small force to locate the device only.
- the gas pressure in the wearer's mouth 22 squeezes the lips 22T and 22B against the top and bottom lip members 26 and 28 respectively and against themselves to substantially seal the mouth.
- the seventh embodiment can be produced by suspending the assembled loop of the wires 76 and 78 and the members 81 within an aluminium mould and then injecting the mould under pressure with liquid silicone rubber, such as the Silastic 94-595-HC previously described. The mould is then baked for about an hour at 180 degrees Celsius to cure the rubber.
- the other embodiments can be produced in a similar manner.
- the seal between the lips and the device can be improved by providing extra grip between the lips and the contact surface of the lip members for example by making or coating the lip members with a material having a high co-efficient of friction or a non-toxic releasable adhesive, or by providing longitudinal grooves in the contact ' surfaces of the top and bottom lip members 26 and 28. All of the above embodiments are preferably manufactured from Silastic 94-
- the device according to the present invention provides advantages over those of the prior art.
- the device does not require a high force on the head strap to retain the device in place, thereby increasing the comfort of the wearer.
- the present invention provides a high degree of safety because a negligible restraining force is required to produce a seal. As a result, the wearer may easily break the seal to talk, cough or breathe through the mouth should the need arise.
