  • a vent for washout of the bias flow or expired gases to the atmosphere is generally provided for example, as part of the mask, or in the case of some respirators where a further conduit carries the expiratory gases, at the respirator.
  • a further requisite of such masks is the washout of gas from the mask to ensure that carbon dioxide build up does not occur over the range of flow rates.
  • typical flow rates in CPAP treatment usually between 4 cm H 2 O to 20 cm H 2 O, prior art attempts at such vents have resulted in excessive noise causing irritation to the user and any bed partners.
  • the invention consists in a device for delivering a supply of gases to a user from a breathing assistance apparatus comprising:
  • a patient interface engaging with said user and thereby supplying said gases to said user.
  • a connector adapted to fluidically communicate said patient interface with said breathing assisting apparatus, including a plurality of outlet vents formed in a flexible portion thereof, said outlet vents adapted to pass a substantial portion of the expired gases of said user.
  • the present invention comprises a device for delivering a supply of gases to a user comprising:
  • a mask having a frame and a substantial seal to the face of said user, adapted to be in fluid communication with said supply of gases,
  • first engagement means adapted to engage said nasal mask to the head of a user
  • second engagement means adapted to pivotally engaged said frame to the head of a user, said second engagement means having at least one configuration, a first configuration such that in use said engagement means may freely pivot with respect to said frame.

  • the present invention provides improvements in the delivery of CPAP therapy.
  • a patient interface is described which is quieter for the user to wear and reduces the side leakage as compared with the prior art.
  • the patient interface as described in the preferred embodiment of the present invention can be used in respiratory care generally or with a ventilator but will now be described below with reference to use in a humidified CPAP system.
  • the present invention can be applied to any form of patient interface including, but not limited to, nasal masks, oral masks and mouthpieces
  • CPAP Continuous Positive Airway Pressure
  • a patient 1 is receiving humidified and pressurised gases through a patient interface 2 connected to a humidified gases transportation pathway or inspiratory conduit 3 .
  • delivery systems could also be VPAP (Variable Positive Airway Pressure) and BiPAP (Bi-level Positive Airway Pressure) or numerous other forms of respiratory therapy.
  • Inspiratory conduit 3 is connected to the outlet 4 of a humidification chamber 5 which contains a volume of water 6 .
  • Inspiratory conduit 3 may contain heating means or heater wires (not shown) which heat the walls of the conduit to reduce condensation of humidified gases within the conduit.
  • Humidification chamber 6 is preferably formed from a plastics material and may have a highly heat conductive base (for example an aluminium base) which is in direct contact with a heater plate 7 of humidifier 8 .
  • Humidifier 8 is provided with control means or electronic controller 9 which may comprise a microprocessor based controller executing computer software commands stored in associated memory.
  • water vapour begins to fill the volume of the chamber above the water's surface and is passed out of the humidification chamber 5 outlet 4 with the flow of gases (for example air) provided from a gases supply means or blower 15 which enters the chamber through inlet 16 . Exhaled gases from the patient's mouth are passed directly to ambient surroundings in FIG. 1.
  • gases for example air
  • Blower 15 is provided with variable pressure regulating means or variable speed fan 21 which draws air or other gases through blower inlet 17 .
  • the speed of variable speed fan 21 is controlled by electronic controller 18 (or alternatively the function of controller 18 could carried out by controller 9 ) in response to inputs from controller 9 and a user set predetermined required value (preset value) of pressure or fan speed via dial 19 .
  • the patient interface is shown in FIG. 2 as a nasal mask.
  • the mask includes a hollow body 102 with an inlet 103 connected to the inspiratory conduit 3 .
  • the mask 2 is positioned around the nose of the user 1 with the headgear 108 secured around the back of the head of the patient 1 .
  • the restraining force from the headgear 108 on the hollow body 102 and the forehead rest 106 ensures enough compressive force on the mask cushion 104 , to provide an effective seal against the patient's face.
  • the hollow body 102 is constructed of a relatively inflexible material for example, polycarbonate plastic. Such a material would provide the requisite rigidity as well as being transparent and a relatively good insulator.
  • the expiratory gases can be expelled through a valve (not shown) in the mask, a further expiratory conduit (not shown), or any other such method as is known in the art.
  • the mask cushion 1104 is provided around the periphery of the nasal mask 1102 to provide an effective seal onto the face of the user to prevent leakage.
  • the mask cushion 1104 is shaped to approximately follow the contours of a patient's face.
  • the mask cushion 104 will deform when pressure is applied by the headgear 1108 to adapt to the individual contours of any particular user.
  • the mask cushion 1104 is composed of a inner foam cushion 1110 covered by an outer sealing sheath 1112 .
  • the inner cushion 1110 is constructed of a resilient material for example polyurethane foam, to distribute the pressure evenly along the seal around the user's face.
  • the inner cushion 1110 is located around the outer periphery 1114 of the open face 1116 of the hollow body 1102 .
  • the outer sheath 1112 may be commonly attached at its base 1113 to the periphery 1114 and loosely covers over the top of the inner cushion 1110 .
  • the nasal mask 2102 includes a hinged forehead rest 2106 (seen in FIGS. 22 and 23).
  • the attachment of the forehead rest 2106 to the hollow body 2102 effectively allows the forehead rest 2106 to move freely in proximity to the user but with no lateral movement.
  • pins 2130 are provided mounted on a base 2132 attached to the hollow body 2102 . These pins 2130 are co-axial within cylinders 2131 mounted on a bridge member 2136 .
  • harnessing slots 2138 are provided which allow straps from the headgear to be inserted to secure the mask to the headgear.
  • one or more resilient cushions 2140 are provided underneath the top end 2142 of the bridge member 2136 , which rest on the forehead of the user.
  • the cushion 2140 might be constructed of silicon or any foam materials as is known in the art for providing cushioning.
  • the forehead rest 2106 described previously may include a weakened section 2130 at its base 2132 which allows the joining member 2136 to pivot from the hollow body 2102 .
  • the bridge member extends up to the forehead of the user.
  • the mask may include a vertical upwardly extending inlet.
  • the member 2136 is hinged at its base 2132 to either side of the inlet passage. Again the member would then extend to the forehead.
  • any well-known form of hinge can be used to provide the pivoting action.
  • the patient interface 2 is shown in FIGS. 3 to 10 as a mouthpiece.
  • the mouthpiece 50 includes a vestibular shield 49 being a generally flat and generally rectangularly-shaped member in front elevation having a curved profile that reflects the curvature of a user's jaw and in turn the curvature of the labial vestibule region.
  • a gases passageway extends through the vestibular shield from an inlet 51 to an outlet 52 in much the same way as with the earlier embodiments.
  • the inlet 51 is provided by a flattened oval-shaped connector 53 .
  • the outlet 52 has an even more laterally extended flattened oval shape 54 .
  • the mouthpiece 50 includes a tongue depressor 55 extending from the inner face of the vestibular shield 49 .
  • the operation of the tongue depressor will be described further on with reference to FIG. 5.
  • the tongue depressor includes a vertical stiffening flange 56 centrally located on its upper surface and extending from the gases outlet 52 . In use gases flow easily around the stiffening flange 56 effectively bifurcating the gases outlet 52 .
  • the tongue depressor 55 further includes a pair of vertically extending spacers 57 which in use may abut against the roof of the wearer's mouth and ensure that the tongue cannot completely block the air passageway.
  • the sealing effect of the vestibular shield 49 against the lips of the user is enhanced by providing teeth abutments of significantly increased thickness than the raised area 20 of the earlier embodiments.
  • an upper teeth abutment 58 and a lower teeth abutment 59 are provided, with the lower teeth abutment 59 protruding further from the inner face of the vestibular shield 49 than the upper teeth abutment 58 .
  • This difference serves to match the typical over-bite of most users.
  • the abutments 58 and 59 are not required to be wider than the gases outlet 52 .
  • a notch 60 is provided centrally in the upper edge of the vestibular shield 49 to accommodate the upper frenal attachment.
  • a slight bead 61 is provided around the edge of the vestibular shield 49 for user comfort, with the vestibular shield 49 otherwise being very thin for additional suppleness.
  • the mouthpiece 50 is preferably formed by over-moulding a soft and supple material part 70 over a stiffer material part 67 .
  • the passageway-forming insert preferably includes a pair of upper and lower vertical flanges 63 and 64 to fully engage within the supple material.
  • the passageway-forming insert 67 includes the vertically extending stiffening flange 56 of the tongue depressor 55 , together with a curved planar portion 71 forming the backbone of the tongue depressor 55 .
  • the vertically extending spacers 57 are of the soft and supple material and are part of the over-moulding 70 , as are the upper and lower teeth abutments 58 and 59 .
  • FIG. 7 use of the mouthpiece according to FIGS. 4 to 6 is depicted.
  • the upper and lower lips 85 , 86 are further distended by the abutment action of the abutments 75 , 76 against the upper and lower teeth 87 , 88 respectively, thus forming a seal of greater pressure between the lips 85 , 86 and the upper and lower portions respectively of the vestibular shield 49 .
  • a lower face 77 of the tongue depressor 55 impinges if necessary on the upper surface 72 of the tongue 85 and retains the tongue in the lower portion of the mouth. This ensures a clear gases outlet 52 from the gases passageway through the vestibular shield.
  • the vertically extending spacers 57 if forced by pressure from the tongue, will engage against the roof of the user's mouth and maintain a clear air passageway. This stops the sleeping patient unconsciously blocking the oral passageway and reverting to nasal breathing.
  • FIG. 8 of the present invention is illustrated including an extra-oral sealing flap 110 .
  • the flap 110 in its natural bias is tapered, the wide open end of which is shaped to conform to the facial contours around the outside of the mouth of a user.
  • the narrow end joins to a cylindrical section, which is designed to slide over the inlet port 114 of the mouthpiece 112 . While this is one method of attachment the flap 100 might also be constructed as an integral part of the mouthpiece 112 .
  • the flap 110 needs to be constructed of flexible material, therefore materials such as silicone rubber can be employed to fashion the flap.
  • the outer flap 110 is seen in FIG. 9, in a bent back position. It will be appreciated that when the mouthpiece 112 is being inserted into the mouth of a user, the outer flap 110 is intended to be in this bent back position to aid insertion. Prior to insertion, the outer flap is bent back by simply pressing on its outer periphery 116 , until it snaps into the bent back position, in which it will stay unaided.
  • FIG. 10 we see the outer flap 110 in use with the mouthpiece 112 in the mouth 117 of a user 120 .
  • the outer flap 110 maybe adjusted into its operational position by pressing on its outer periphery 116 until it snaps back to press against the outside of the mouth 118 . Due to the relative position of the vestibular shield 122 and the outer flap 110 , the outer flap 110 is unable to fully reach its natural bias and thereby inflicts a compressive force on the outside of the mouth 118 .
  • the outer flap 300 is shown in perspective. Included are ventilation apertures 302 , 303 either side of the gases port 304 , which are surrounded by a ridge 306 acting as a moisture barrier.
  • the apertures 302 , 303 are provided such that any excess moisture leaking from the mouth will migrate to the apertures where they may evaporate. Small vents in the conduit may be used to direct small amounts of pressurised gas at the apertures to aid evaporation.
  • the ridge 306 is included to ensure that no moisture migrates further into the sealing region 308 , as this would be detrimental to the sealing properties of the flap.
  • FIG. 3 Attention is now directed to FIG. 3. It has been found that an additional factor in the effectiveness of any patient interface 2 , is the manner in which the interface is connected to the breathing circuit 41 .
  • the weight of the breathing circuit 41 and any attempted movement of one other of the breathing circuit 41 and the interface 2 relative to the other, is one of the largest influences tending to dislodge the interface 2 . It must be noted that the interface 2 must remain in position and maintain a seal during all sleep, when the user has no muscle tone.
  • connection 40 as provided in the present invention between the breathing circuit 41 and the interface 2 decouples the interface 2 from the breathing circuit 41 .
  • the connection 40 is effective in reducing the forces placed on the interface 2 by the breathing circuit 41 when the user moves around during sleep.
  • the breathing circuit 41 is laid across the chest 43 of the user, and may be secured to the user's bed clothes or sleeping garments.
  • the breathing circuit 41 is preferably laid on the chest of the user to take the weight of the breathing circuit 41 off of the interface 2 .
  • an L-shaped elbow 45 is incorporated in the connection 40 .
  • the elbow 45 may be incorporated in the interface 2 .
  • the elbow 45 is formed at a right angle and provides a positive pressure on the interface 2 .
  • the elbow 45 may include a swivel joint and may be disconnected from gaseous outlet 42 .
  • the connection 40 further includes an extremely flexible connecting tube 46 provided between the elbow 45 and the breathing circuit 41 .
  • the connecting tube 46 is preferably connected to the breathing circuit 41 by a swivel joint 48 for reasons described herein.
  • the breathing circuit 41 while flexible, will necessarily be stiff enough to maintain its integrity over comparatively long tuns, while the connecting tube 46 , being only a short length, for example 10 centimetres, merely has to span between the user's mouth and chest, and can thereby be made in a manner that would not be suitable for long runs. Furthermore, as a result of the short length of the connecting tube 46 , the connecting tube 46 does not need to incorporate significant insulation or heating capability.
  • the connecting tube 46 may be formed from a thin plastic membrane supported over a helical or double helical or corrugated supporting ribs. In such a case, the support makes the connection tube 46 laterally flexible and resistant to torsion.
  • the elbow swivel joint 45 allows for movement of the connection tube 46 relative to the interface 2 .
  • the swivel joint 48 allows for movement of the connection tube 46 relative to the breathing circuit 41 . It is to be understood that one or both of the swivel joints 45 , 48 could be eliminated, but the preferred embodiment includes swivel joint 48 .
  • FIGS. 12 to 17 In order to reduce the noise caused by expiratory gases being expelled from the patient interface 2 , the present invention is illustrated in FIGS. 12 to 17 with the elbow connector (previously designated as 45 ) including an outlet vent. It would be appreciated by one skilled in the art that the elbow connector as described herein will be equally applicable to all proceeding embodiments and all other forms of patient interface for delivering CPAP therapy.
  • the elbow connector is illustrated including a flexible sleeve 400 which fits overtop of the elbow connector.
  • the sleeve 400 is preferably constructed of silicon, but it will be appreciated by one skilled in the art that a number of other flexible materials will be equally applicable.
  • the sleeve 400 includes locating indents 402 which once installed on the elbow connector match up with and lock into locating notches 404 on the elbow connector. The location is necessary so that the outlet aperture 406 in the elbow connector always matches up with the outlet vents 408 in the outlet sleeve 400 . This then prevents the undesirable situation where the sleeve could slip and the outlet vents 408 not match up with the outlet aperture 406 with resulting consequences to the patient.
  • the present invention is shown with a one-piece elbow.
  • the elbow is preferably constructed of either “Hytrel” plastic or polycarbonate.
  • the elbow connector is manufactured to have a thin portion 410 surrounding the outlet vents 412 in comparison to the remainder of the elbow connector which is considerably thicker.
  • the properties of the material chosen for the elbow connector are such that its flexibility is dependent on its thickness. Therefore in the thin section 410 the elbow connector is relatively flexible and in the remainder is relatively rigid.
  • the outlet vents 412 which are also rounded on their periphery are formed in a flexible portion, and therefore achieve the desirable low noise properties when expiratory gases are vented therethrough.
  • FIG. 17 includes a mouthpiece with a flow diffuser 500 .
  • the mouthpiece sits with a vestibular shield 502 between the gums 504 and the lips 506 of a user.
  • An outer flap 508 provides compressor force on the lips 506 to keep the mouthpiece in place in the user's mouth.
  • the mouthpiece includes a tough depressor 510 extending into the user's oral cavity.
  • the delivered gases would flow through passageway 512 in the mouthpiece, causing a relatively concentrated flow of gases to flow through the oral cavity and down the airway.
  • the flow diffuser 500 fitted overtop of the passageway 512 the flow is defused over the much larger area of the diffuser 500 , and therefore both the speed and side effects are reduced.
  • the space between the passageway 512 and the diffuser 500 could be filled with a Humidity Moisture Exchange (HME) material. This would allow moisture through on the inspiratory flow put prevent it passing out an expiration. This would further prevent against the patient's passageways drying out. Further, if the HME material was in the form of foam, then it might also act as the diffuser 500 . It will also be appreciated that the HME material could be used in the space 516 all the way out to the elbow connector (not shown) to maximise its effect.
  • HME Humidity Moisture Exchange
  • the present invention effectively minimises the noise generated by the outward flow of expiratory gases from the mask.
  • the present invention requires little or no maintenance.
  • the present invention also provides a flow diffuser for use with the mouthpiece, which reduces any side effects of orally delivered CPAP therapy and improves user comfort.
