Definitions
- This invention relates to a mask for supplying gases, typically fresh air or oxygen to the airways of humans.
- a first category positive pressure is applied to the lungs for the purpose of stabilising the lungs, and in particular for maintaining a minimum inflation level of the small air spaces in which gas transfer occurs (the alveoli).
- This therapy is very useful in patients with a variety of lung diseases, where the disease process tend to lead to collapse (closure of the airway containing regions of the lung).
- nasal CPAP nasal continuous positive airway pressure
- OSA obstructive sleep apnea
- Obstructive sleep apnea is a condition in which the upper airway closes in sleep, and does so repeatedly.
- Nasal CPAP when applied for the duration of sleep, stabilises the upper airway and allows for normal sleep and normal breathing.
- Masks for applying nasal CPAP, or nasal pressure support ventilation have a requirement to be able to deliver pressure and flow and maintain pressures within the mask without permitting leaks.
- Leaks are undesirable as they can allow the pressure in the mask to drop below a therapeutic level. Leaks may also be an irritation particularly, if the leak causes jets of air/oxygen to be directed into the patient's eye. Leaks interrupt a patient's sleep which is undesirable as interrupted sleep is known to be of much less value than uninterrupted sleep. Further, as the masks are for use during natural sleep, a high level of comfort in the fit of the mask is necessary.
- One very common mask design includes three separate components as follows:
- a soft mouldable rubberised interface which comes in direct contact with the patient's facial skin.
- a rigid manifold to which the soft interface is connected, and which covers the patient's nose.
- the manifold includes :- a) connector lugs to which straps from a harness are connected; b) connections to an air delivery pipe; and c) a number of relatively small holes or equivalent feature to provide a controlled leak of air to the atmosphere.
- a harness which goes around the head from which three or more straps extend to connect to the lugs on the rigid manifold.
- a seal is achieved by the mask being pulled onto the face by the straps attached to the rigid manifold. The seal is achieved by the rim of the mask coming into contact with the skin. In this way, direct force is applied via the straps (harnessed place around the head), and transmitted through the rigid manifold.
- the mask described therein has a face contacting portion which is formed from an elastomeric material and is shaped to define a large bubble or dome shaped chamber.
- the chamber tends to balloon outwardly and, when fitted to a patient, the face contacting portion is caused to overly a region of the patient's face and seal three dimensionally with the contours of the overlaid facial region.
- the mask is integrated with a rigid shell-like moulding which does not contact the patient's face.
- the shell is provided to enable a gas supply line to be connected to the mask , to facilitate fastening of the mask to a patient's face and to minimise the risk that movement of the gas supply line will disrupt the seal between the mask and the patient's face.
- Movement of the head, and subsequent dislodgment of the mask, and breakage of the seal are major problems with prior art masks. This is a particular problem when a patient lies on their side, with the side of their head on the pillow as the rigid manifold tends to contact the pillow. The contact moves the manifold relative to the patient's face, is transmitted to, and affects the integrity of the seal and also the manifold can be pushed onto the patient's nose causing discomfort to the patient.
- seal breakage is addressed by pulling the straps firm. This however, can lead to discomfort for the patient.
- the bubble provides a continuous rolling seal, so that minor head and other movements are accommodated within the excess thin membrane.
- large head movements may not be accommodated by the rolling seal.
- Australian Patent No 684412 by the same inventor as the earlier Australian patent No 634994, addresses this problem by making a portion of the wall containing the gas supply port exhibit a degree of flexibility that is greater than that of adjacent regions of the mask so that movement by the connecting gas supply line will be accommodated at least in part by flexing of the wall portion. Whilst both masks produce relatively satisfactory seals they are quite bulky, relatively heavy and ungainly. In existing masks, because the straps must anchor onto a rigid point, they are attached to the rigid manifold; the result is that typically the strap leaves the side of the face near the cheeks, and passes through air until it reaches the lug on the manifold.
- This "floating" part of the strap provides a significant weakness and adversely affects the integrity of the seal when the patient's head moves. When the subject rolls onto their side, this floating part of the strap is easily distorted, and pulls on the mask and leads to a leak.
- the present invention seeks to provide an improved mask which reduces the relative size, weight and bulk of the existing masks and yet provides a satisfactory seal.
- a variant of the mask may be used to supply treated air, oxygen or an air/oxygen blend or the like to patients.
- treated air is supplied from a pipe located near a patient's nasal airway and the flow of air is directed past the patient's nares.
- the present invention seeks also to provide harness for supporting a pipe for supplying a flow of gas to a patients nasal airway.
- a mask for supplying gas under pressure to the nasal airway of a human including: a series of flexible stretchable straps formed from an elastomeric material for locating the mask against the human face, the straps being integrally formed or joined to define a perimeter enclosing an aperture adapted to fit around the nasal area of a human, the straps being shaped and configured to approximate to the three dimensional shape of the region around the nasal area of the human face; and a manifold disposed on the non-face contacting side of the face contacting portion, the manifold including means for connection to a gas supply means; the arrangement being such that stretching of the straps around the nasal area of the human causes the straps to mould to the contours of the nasal area of the face so that the straps form a seal around the nasal area which is a relatively tight fitting seal.
- the straps themselves provide the seal. This greatly reduces the size and weight of the mask.
- the patient's nose extends into the manifold.
- the straps closely fit to the patient's face and the problems of flexing due to the connection with the air delivery pipe are reduced.
- Straps for attachment to a head harness are used to define, locate and provide a seal around the perimeter of a patient's nose. Because the straps are sufficiently flexible they can mould around the perimeter, and in doing so, as the mask stretches around the margins a tight fitting comfortable seal is achieved.
- the mask of the present invention allows the straps to pass over the patient's cheeks, rather than "extending" through air down the side of their heads. This provides a more secure fit of the mask and makes the mask less likely to move.
- the aperture may be generally triangular.
- the mask may further include a flexible sealing element extending along one inwardly facing side of each strap.
- the sealing element may be generally convex.
- a channel extends around the perimeter in which an adhesive means (such as "DuoDerm” or Elastogel") for sealably adhering the perimeter to the human facial area and minimising leakage, is provided
- the mask can be made in fewer parts than the mask of AU 684412, typically only two, with the straps and sealing element moulded in one part and the manifold in second part, which can make manufacture of the mask simpler and cheaper.
- three flexible arms extends away from the straps for securing the face-contacting portion to a patient's head or face.
- a pad is defined at the end of each flexible arm distal from the plate.
- the pad may define slots so as to be connectable to harness straps attached to a cap. These harness straps could be connected to the pads by fastening materials such as velcro or the like
- the pads, straps and sealing element are all integrally moulded from an elastomeric material, typically a high tear resistant silicone elastomer such as Silastic (Registered Trade mark of the Dow Corning Corporation) or Santoprene (Registered Trade Mark of Monsanto Co).
- elastomeric material typically a high tear resistant silicone elastomer such as Silastic (Registered Trade mark of the Dow Corning Corporation) or Santoprene (Registered Trade Mark of Monsanto Co).
- the thickness of the straps is typically between 2 to 4mm.
- a number of small holes will be defined on the manifold to provide a constant leak to atmosphere and thus a way out for expired air.
- the number and size of the holes are determined by the pressure of air supplied to the mask and flow delivery system and are chosen to enable the desired pressure and air flow through the mask.
- part of the manifold extends along one of the arms of the mask, typically the arm which extends from the top of the mask where an air port or hole for receiving a gas delivery pipe is provided.
- the manifold is typically made of the same thin flexible elastomeric material that is used for the straps. Typically, the material forming the manifold is about lmm thick.
- the manifold should ideally be somewhat larger than a typical human nose. In this manner when a person lies on their side with the side of their head on a pillow, movement of the head can be accommodated by flexing and compression of the manifold. Because the manifold is soft and flexible, this movement is not transmitted to the seal but is largely absorbed by flexing of the manifold. Also because the manifold is flexible, any contact of the manifold with a patient's nose should not cause discomfort to the patient.
- the mask includes a harness and an air pipe extending to a junction port attachable to the top of a patient's head and an air delivery pipe is rotatably mounted to that junction port, thus allowing a patient's head to turn without moving the air delivery pipe.
- the present invention also encompasses a method of supplying gas to the airway of a human using any of the aspects or embodiments of the invention described above.
- the method will be used to supply oxygen or air to the airway for nasal CPAP, or nasal ventilation or nasal pressure support.
- a variant of the mask may be used to supply treated air, oxygen or an air/oxygen blend or the like to patients wherein the mask is open or merely acts as a harness or anchor for air pipes for directing a flow of air past the patient's nares and for creating a zone of clean air around a patient's nares.
- a harness for supplying gas under pressure to the nasal airway of a human including: a series of flexible stretchable straps formed from an elastomeric material for locating the harness against the human face, the straps being, integrally formed or joined to define a perimeter enclosing an aperture adapted to fit around the nasal area of a human, the straps being shaped and configured to approximate to the three dimensional shape of the region around the nasal area of the human face; and a means for supplying a flow of gas directed generally towards the perimeter of the harness including means for connection to a gas supply means; the arrangement being such that stretching of the straps around the nasal area of the human causes the straps to mould to the contours of the nasal area of the face so that the straps anchor the harness to the human face relatively tightly.

- Figure 4 is an isometric view of a manifold for the mask shown in Figures 1 to 3;
- Figure 5 is a side view of the manifold shown in Figure 4;
- Figure 6 is an isometric view of a complete mask combining the mask of Figures 1 to 3 and the manifold of Figures 4 and 5;
- Figure 7 is a section through the mask of Figure 6;
- Figure 8 is a schematic drawing illustrating a head mounted junction port for receiving an air delivery pipe;
- Figure 9 shows a variant of the mask of Figure 6;
- Figure 10 shows an isometric view of a variant of the mask of Figure 1;
- Figure 11 shows an underneath plan view of the variant of Figure 10.
- Figure 1 shows a part 10 of a mask.
- the mask includes three straps, 12, 14, 16 which are integrally moulded with a generally triangular face engaging portion or perimeter 18 enclosing a generally triangular aperture 20.
- the straps can be considered to be an extension of members defining the perimeter as the straps 12, 14, 16 are integrally formed and connected via the perimeter.
- straps 12 and 14 are connected via perimeter member 22, and pulling on the ends of straps 12 and 14 also stretches perimeter member 22.
- straps 12 and 16 are integrally formed and connected by perimeter member 24, and straps 16 and 14 by perimeter member 26.
- the perimeter 18 is integrally formed with the straps from a flexible stretchable elastomeric material (such as Silastic or Santoprene) and when the straps are stretched in a direction as shown by the arrows A, B and C, then the face engaging portion perimeter stretches also and the aperture 20 enlarges slightly.
- a flexible stretchable elastomeric material such as Silastic or Santoprene
- the face engaging portion 18 of the mask and the straps themselves, particularly the top strap 16, are moulded so that they tend to approximate to the contours of a human face.
- the upper part of the face engaging portion includes a generally concave portion 30 which fits tightly over the bridge of a patient's nose.
- FIG. 4 and 5 illustrate a manifold 40 which defines an open face 42 which defines an open face 42 which sealingly mates with the non-face engaging side 10A of the mask 10 and the two components 10 and 40 may be glued or otherwise fixed together to form a complete mask 50 as shown in Figures 6 and 7.
- the manifold is flexible and compressible in contrast with the prior art, allowing movement of a patient's head lying side-on on a pillow, to be accommodated by compression or deformation of the manifold.
- an air port 52 for connection to an air delivery pipe is located at a distal end of the strap 16 remote from the aperture 10.
- This membrane may be lmm thick or less.
- the principal of operation of the mask is similar to that of pulling on a tight fitting garment.
- the nose and its surrounds could be considered to be a cone and the perimeter 18 is an elastic funnel shaped to approximate to the cone yet with slightly smaller margins and an open central region.
- the inner margins of the funnel contact the surface of the cone and then stretch around it causing a closed seal.
- the margins of the mask are the perimeter members. As these members stretch, they pull inwards to the skin on the face and are at all times in direct contact with the skin.
- Figure 8 illustrates a variant of the invention where a short pipe 60, which may be an extension of the manifold and strap 16 extends to an air port junction 62 fixed to the top of a patient's head.
- An elbow pipe 64 is rotatably mounted in the air port junction 62 rotating about axis Z perpendicular to the top of the patient's head.
- the elbow 64 is connected to an air delivery pipe 66. With this arrangement, the patient's head can turn without being affected or affecting delivery pipe 66.
- FIG. 9 illustrates a variant 100 of the mask of Figure 6.
- the mask of Figure 9 is used for supplying clean filtered air, treated air, or an air/oxygen blend to a patient where it is not necessary or desirable for the patient to wear a closed mask enclosing the patient's nose. Closed masks tend to uncomfortable when worn for long periods of time. Further if humid air is supplied by a closed mask to an asthma sufferer for example, water will tend to condense inside the closed mask which is undesirable.
- the manifold is replaced by a canopy or hood 102 which directs air under pressure 104 down the canopy towards the patient's nares.
- the base 106 of the canopy is open, being either totally open, or as illustrated in Figure 9 defining a large number of relatively large diameter holes 108 typically having a diameter of about 5mm to 10mm or more.
- the straps which are always in contact with the skin this provide a very stable anchoring of the mask on the face.
- no seal is required.
- This arrangement allows a relatively high volume fast flow F of low pressure air past a patient's nares and creates an atmosphere around the nares which is dominated by the low pressure air or air/oxygen mix.
- the canopy is preferably transparent as shown in Figure 9. The same effect may be created by simply forming a large number of relatively large diameter holes, say 5 to 10mm or more in the base of manifold of the mask of Figure 6.
- pipes 152, 154 extend along each of the straps 12, 14 respectively and terminate in open ends 156, 158 adjacent the perimeter 18 of the mask/harness.
- the straps which are always in contact with the skin provide a very stable anchoring of the mask on the face. Again in contrast with the mask of Figures 1 to 8, no seal is required.
- a flow of pressurised filtered clean air passes along the pipes 12 14 as shown by the arrows F.
