    CROSS REFERENCE TO RELATED ORDERS
    [001] This patent application claims the benefit of priority under Article 35 USC § 119(e) of US Provisional Patent Application No. 61/671,926, filed June 16, 2012, the contents of which are here incorporated for reference. HISTORY OF THE INVENTION1. FIELD OF THE INVENTION
    [002] The present invention pertains to patient interface devices structured to administer a flow of breathable gas to a user, and in particular to a support-style sealing pad for a patient interface device that has lateral stabilizers providing an improved fit and seal.2. DESCRIPTION OF RELATED TECHNIQUE
    [003] There are numerous situations where it is necessary or desirable to administer a flow of breathable gas noninvasively to a patient's airway, that is, without intubating the patient or surgically inserting a tracheal tube into the patient's esophagus. For example, it is known to ventilate a patient using a technique known as non-invasive ventilation. It is also known to administer positive airway pressure (PAP) therapy to treat certain medical disorders, the most notable of which is OSAS (Obstructive Sleep Apnea Syndrome). Known PAP therapies include continuous positive airway pressure (CPAP), in which a constant positive pressure is provided to the patient's airway to keep the patient's airway open, and variable airway pressure, in which the pressure provided to the patient's airway varies with the patient's respiratory cycle. Such therapies are typically provided to the patient at night while the patient is asleep.
    [004] Pressure support and non-invasive ventilation therapies, as described above, involve placing a patient interface device including a mask component having a soft flexible sealing pad on the face of a patient. The mask component may be, without limitation, a nasal mask that covers the patient's nose, a nasal/oral mask that covers the nose and mouth, or a full face mask that covers the patient's face. Such patient interface devices may also employ other patient-contacting components, such as forehead supports, cheek pads and chin pads. The patient interface device is connected to a gas delivery tube or conduit and interfaces the ventilator or pressure support device with the patient's airway so that a flow of breathable gas can be delivered from the pressure/flow generation device for the patient's airway. It is known to hold such devices on a wearer's face via a mask holder having one or more straps adapted to fit over/around the patient's head.
    [005] One type of sealing pad is called a stand-style sealing pad. A support-type sealing pad is structured to lie under the patient's nose and provide an airtight seal against the surfaces of the nasal septum and nostrils (and possibly also the upper lip). A major disadvantage of current support-type sealing pads is that the seal between the pad and the nose is very sensitive to the alignment of the pad with the nose. For this reason, many wearers find it difficult to maintain a reliable seal when using a mask with a support-type sealing pad due to misalignment caused by wearer movement or external forces acting on the mask (eg from a pillow). When the seal is broken, the ability of the respiratory therapy device to deliver adequate airflow to the user may be compromised. Additionally, the air leak can be directed over the user's face, causing discomfort. SUMMARY OF THE INVENTION
    [006] Thus, it is an objective of the present invention to provide a support-type sealing pad that overcomes the deficiencies of conventional support-type sealing pads. This object is achieved in accordance with an embodiment of the present invention by providing a support-type sealing pad that includes side stabilizers providing an improved seal and fit.
    [007] In one embodiment, the support-type pad for a patient interface device is provided that includes a central sealing body part defining an inner chamber, the central sealing body part including a front wall, a rear wall , a top wall and a back wall. The upper wall includes a central sealing surface structured to engage the septum and a bottom of each nostril of a patient (and possibly the portion of the patient's mouth above the upper lip) when the patient interface device is used by the patient, a first stabilizing surface and a second stabilizing surface, the first and second stabilizing surfaces each extending upwardly and outwardly with respect to the central sealing surface and an upper edge of the front wall in a direction away from the bottom wall and being structured to enclose and in parts thereof, an outer side (cross-to-bottom) of a respective one of the nostrils fits wherein the patient interface device is used by the patient, wherein the first stabilizing surface includes a first side edge portion and the second stabilizing surface includes a second part of the front side edge, and where the top edge of the wall fr Therefore, the first front side edge portion and the second front side edge portion together define a front opening of the center seal body portion.

    [022] A system 2 adapted to provide a regimen of respiratory therapy to a patient in accordance with an exemplary embodiment of the invention is shown generally in FIG. 1. System 2 includes a pressure generating device 4, an administration conduit 6, and a patient interface device 8. The pressure generating device 4 is structured to generate a flow of breathable gas and may include, without limitation, ventilators, constant pressure support devices (such as a continuous positive airway pressure device, or CPAP device), variable pressure devices (eg, manufactured and manufactured BiPAP®, Bi-Flex®, or C-Flex™ devices distributed by Philips Respironics of Murrysville, Pennsylvania), and self-titrating pressure support devices. The administration conduit 6 is structured to communicate the flow of breathable gas from the pressure generating device 4 to the patient interface device 8.
    [023] In the exemplary embodiment, the patient interface device 8 comprises a frame-type nasal mask to fit the patient's nose and provide a seal against the surfaces of the nasal septum and nostrils (and possibly the mouth portion of the above the upper lip) as described in detail here. In the present embodiment, the patient interface device 8 includes a holder-type sealing pad 10 coupled to a tube assembly 12. As seen in FIG. 1, tube assembly 12 includes a first arm 14A structured to lie along a first side of the patient's head and a second arm 14B structured to lie along the second side of the patient's head when the patient interface device 8 is used by the patient. A first end of the first arm 14A and a first end of the second arm 14B are each fluidly coupled to the holder-type sealing pad 10. Additionally, a second end of the first arm 14A and a second end of the second arm 14B are each fluidly coupled to a mating connector 16 structured to remain over the top of the patient's head when the patient interface device 8 is used by the patient. The delivery conduit 6 is fluidly coupled to the coupling connector 16 to allow the flow of breathable gas from the pressure generating device 4 to be communicated to the support-type sealing pad 10 through the tube assembly 12, and then to the airway of a patient. The straps 18 of a helmet component are connected to the first arm 14A and a second arm 14B through fastening members 20 to secure the patient interface device 8 to the patient's head.
    [024] FIG. 2 is an isometric front view, FIG. 3 is a front elevation view, FIG. 4 is a side elevation view, FIG. 5 is a rear elevation view, and FIG. 6 is a top plan view of support-type sealing pad 10 in accordance with an exemplary embodiment of the present invention. In the exemplary embodiment, the support-type sealing pad 10 is defined from a single piece of soft, flexible cushion material, such as, among others, silicone rubber, an appropriately soft thermoplastic elastomer, a fabric, or any combination of such materials. It will be understood, however, that the support-type sealing pad 10 need not be unitary within the scope of the present invention. Instead, the support-type sealing pad 10, and parts thereof, may be made of separate components that are coupled together by suitable means.
    [025] The support-type sealing pad 10 includes a central sealing body portion 22 defining an inner chamber, a first access portion 24A provided over and extending from a first side of the central sealing body portion 22, and a second access portion 24B provided on and extending from the second opposite side of the central sealing body portion 22. The first access portion 24A and a second access portion 24B are fluidly coupled to the inner chamber of the portion of the central sealing body 22. The first access portion 24A includes a first opening 26A and is structured to be fluidly coupled to the first arm 14A, while the second access portion 24B includes a second opening 26B and is structured to be fluidly coupled to the second arm 14B.
    [026] [The central sealing body portion 22 includes a front side 28 including a front wall 29 and a rear side 30 opposite the front side 28 and including a rear wall 31. A plurality of exhaust holes 32 is provided in the wall front 29 and acts as an exhaust port for the patient interface device 8. The exhaust ports 32 can be directed in any direction (or combination of directions) including directly away from the user (as illustrated in the illustrated embodiment), towards the top of the user's head, down towards the user's chin, or to the other sides. Alternatively, an exhaust port in the form of a semi-permeable porous material, such as a fabric, can be provided in place of the exhaust ports 32. The central sealing body portion 22 also includes a top wall 34 and a bottom wall 36 opposite the top wall 34.
    [027] The top wall includes a central sealing surface 38 including an orifice 39 (providing access to the inner chamber of the central sealing body portion 22), and the first and second stabilizing surfaces 40A and 40B. In the exemplary embodiment, the central sealing surface 38 is structured to mate and form a seal against the septum and bottom of each nostril of a patient (and possibly the portion of the patient's mouth above the upper lip in a particular embodiment) when the patient interface device is used by the patient. Additionally, the first and second stabilizing surfaces 40A and 40B extend upward and outward from the central sealing surface 38 (and the upper edge of the front wall 29) in a direction away from the bottom wall 36 (and the upper edge of the front wall 29), and are structured to wrap around and in parts thereof, contact the outer sides (across the bottom) of the patient's nostrils (the flaps) when the patient interface device 8 is used by the patient.
    [028] As seen in FIGS. 2 and 3, in the exemplary embodiment, the junction of the first and second stabilizing surfaces 40A and 40B with the central sealing surface 38 each comprises a rounded filament portion (forming a part of the first and second stabilizing surfaces 40A and 40B in the exemplary embodiment) that in each case it provides a smooth transition between the two surfaces. Additionally, the first stabilizing surface 40A and the second stabilizing surface 40B are provided between the upper edge of the front wall 29 and the upper edge of the rear wall 31. In the non-limiting exemplary embodiment, the first stabilizing surface 40A is generally triangular in shape including a base portion 42A, a front side edge portion 44A, a rear side edge portion 46A, and an apex portion 48A. Similarly, in the non-limiting exemplary embodiment, the second stabilizing surface 40B also has a generally triangular shape including a base portion 42B, a front side edge portion 44B, a trailing side edge portion 46B, and an apex portion 48B.
    [029] Thus, as seen more readily in FIG. 3, the upper edge of the front wall 29, the front side edge portion 44A and the front side edge portion 44B together define a front opening 50 of the central sealing body portion 22 that exposes the front and upper portion of the patient's nose. (ie, the support-type sealing pad 10 does not cover the front and top of the patient's nose). The significance of this feature is described elsewhere here. Also, the upper edge of the rear wall 31, the rear side edge portion 46A and the rear side edge portion 46B together define a rear opening 51 of the central sealing body portion 22 which is structured to receive the patient's nose therethrough. . In alternative embodiments, the first and second stabilizing surfaces 40A, 40B may have other shapes, such as generally rectangular or trapezoidal shapes.
    [030] Furthermore, as seen in FIG. 3, the support-type sealing pad 10 has a transverse axis 52 which is a line of symmetry for the support-type sealing pad 10. The transverse axis 52 is perpendicular to a longitudinal axis 54 of the central sealing body portion 22 , shown in FIGS. 3 and 4. Additionally, as shown in FIG. 6. A centerline 56 of the center sealing surface 38 extends through the middle of the center sealing surface 38 from the center of the front side 28 (and the front wall 29) to the center of the rear side 30 (and the wall rear 31) . The centerline 56 remains within and defines a sealing plane of the holder-type sealing pad 10. In the non-limiting exemplary embodiment, the sealing plane of the holder-type sealing pad 10, when viewed from the front as shown in FIG. 3, is not orthogonal to the transverse axis 52, but instead is angled and extends/inclines down from the front to the rear at an angle slightly greater than zero at thirty degrees with respect to a line or axis that is orthogonal to the transverse axis 52.
    [031] In another exemplary embodiment, the sealing plane of the support-type sealing pad 10, when viewed from the front as shown in FIG. 3, is an axis orthogonal to the transverse 52. In yet another exemplary embodiment, the central sealing surface 38 is not flat, but preferably actually has an arc where the apex is not necessarily on the front edge, but rather, closer to the middle of the central sealing surface 38. These axes, lines and planes help define another important aspect of the holder-type sealing pad 10. In particular, the first and second stabilizing surfaces 40A and 40B each include a contact portion. 41A, 41B which is structured to fit the outer side of the patient's nostrils (the flaps) when the patient interface device 8 is used by the patient. In the exemplary embodiment, at any point along the surface of the contact parts 41A and 41B, the contact parts 41A and 41B are configured to remain at an angle θ1 (FIGS. 7 and 8) (which may be constant or vary within contact parts 41A and 41B) with respect to the sealing plane (marked 58 in FIG. 7) of the holder-type sealing pad 10 which is less than or equal to 135 degrees and greater than or equal to 30 degrees. In a particular exemplary embodiment, at any point along the surface of the contact parts 41A and 41B, the contact parts 41A and 41B are configured to lie at an angle θ1 with respect to the sealing plane 58 which is less than or equal to 90 degrees and greater than or equal to 30 degrees. A complementary angle θ2 is also shown in FIG. 7, where θ2 is measured with respect to a plane 60 that is orthogonal to the fence plane 58 and is less than or equal to 60 degrees and greater than or equal to -45 degrees (less than or equal to 60 degrees and greater than or equal to 0 degrees in particular exemplary achievement).
    [032] In the exemplary embodiment, the distance between the contact parts 41A and 41B is 25 mm to 55 mm.
    [033] The combination of the side stabilizer pieces comprising the first and second stabilizer surfaces 40A and 40B and the open front part (opening 50) serves to direct any air leakage away from the user, while blocking the flow of air leakage from the sides of the support-type sealing pad 10. In particular, as seen in FIGS. 9 and 10, the helmet attachment points 62 serve to anchor the support-type sealing pad 10 to the face, but an external force (eg gravity) of sufficient magnitude could cause the support-type sealing pad 10 rotate around this anchor point (FIG. 10). Referring to FIG. 10, the support-type sealing pad 10 is blocked by the patient's nose from rotating in a counterclockwise direction, but could potentially rotate clockwise away from the nose. In this situation, the seal adjacent to the face would be maintained, preventing air from squirting into the user's face, while the open front of the support-type sealing pad 10 (opening 50) facilitates the flow of air away from the user, thus minimizing the discomfort.
    [034] FIGS. 11-13 show support-type sealing pads 10', 10" and 10"' according to the alternative embodiments in which the first and second stabilizing surfaces 40A', 40A", 40A'" and 40B', 40B'' , 40B"' of these curve around towards the tip of the nose in varying degrees while still maintaining a 50', 50'', 50''' front opening. Maintaining a wider front opening can help accommodate the extreme length nose, while maintaining a narrower opening can provide increased stability due to the larger matching stabilizing surfaces.
    [035] In the embodiments of FIGS. 1-13, support-type sealing pads 10, 10', 10" and 10"‘ are shown and described in a resting, non-inflated/undeformed state (i.e., no pressurized gas in them). FIG. 14 shows an alternative system 2-1 having an alternative support-type sealing pad 10-1 in which in a non-inflated/non-deformed rest state, the first and second stabilizing surfaces 40A-1 and 40B-1 of these can either does not meet the angular specifications (θi and θ2) described here with respect to the support type sealing pad 10, but where in an inflated/deformed state 10 (responsive to an internal pressure of 4-30 cmH20), the sealing pad of the support type 10-1 will expand (see arrows in FIG. 14) and the first and second stabilizing surfaces 40A-1 and 40B-1 of these will be brought to meet the angular specifications (θ1 and θ2) described here in relation the support-type sealing pad 10 and will be brought to fit outside the patient's nostrils. Additionally, the support-type sealing pads described here could be constructed of a very soft material (eg, soft silicone, or gel, or a visco foam) which could be deformed by contact with the facial anatomy so that the former is second stabilizing surfaces 40A-1 and 40B-1 of these would be brought to meet the angular specifications (θ1 and θ2) described here with respect to the support type sealing pad 10 (in the resting state, these conditions may or may not be met).
    [036] A 2-2 system adapted to provide a respiratory therapy regimen to a patient in accordance with an alternative exemplary embodiment of the invention is shown generally in FIG. 15. System 2-2 includes a pressure generating device 4 and a delivery conduit 6 as described herein. System 2-2 includes an alternate patient interface device. Patient interface device 8-2 comprises a strut-type nasal mask structured to fit the nose of the patient, which includes a strut-type sealing pad 10-2 which is similar to strut-type sealing pad 10. More specifically, the support-type sealing pad 10-2 includes a central sealing body portion 22-2 defining an inner chamber that is similar in structure to the central sealing body portion 22 in that it includes first and second stabilizing surfaces 40A -2 and 40B-2 having contact parts that meet angular specifications (θ1 and θ2) described herein with respect to the support-type sealing pad 10 and a front opening 50-2 similar in structure to the front opening 50. Rather than having access portions 24A, 24B that are attached to the tube assembly 12, the sides of the support-type sealing pad 10-2 are attached (not fluidly) to the arms of the helmet assembly 64. Additionally, the front of the p. The center seal body portion 22-2 is provided with an orifice 66 that provides access to the inner chamber of the center seal body portion 22-2. An elbow conduit 68 having an exhaust port 70 is fluidly coupled to both the central sealing body portion 22-2 through port 66 and to the dispensing conduit 6 so that pressurized gas from the pressure generating device 4 can be supplied. to the inner chamber of the central seal body part 22-2, and then to the patient's airway.
    [037] FIG. 16 is a top plan view of a strut-type sealing pad 10-3 that is similar to (and may be replaced with) strut-type sealing pad 10 (similar parts marked with similar reference numerals including a "-3" designation ”). However, rather than including a top wall 34 that includes a central sealing surface 38 including a single hole 39, the bracket-type sealing pad 34-3 that includes a central sealing surface 38-3 including a first hole 72A and a second port 72B, wherein each port 72A, 72B is structured to be aligned with a respective nostril of the patient.
    [038] Furthermore, according to yet another embodiment of the present invention, the first stabilizer surface (40A, 40A', 40A", 40A"', 40A-1, 40A-2, 40A-3) and the second stabilizer surface (40B, 40B', 40B", 40B''', 40B-1, 40B-2, 40B-3) (including the transition between the central sealing surface and such lateral stabilizer surfaces) each include at least one portion in which the radius of curvature has a certain minimum value that is within a predefined minimum range. In the exemplary embodiment, this range is from 0 mm to 15 mm. This embodiment is shown schematically in FIGS. 17A, 17B, and 17C, (using the stabilizing surface 40A), wherein in Fig. 17A the part has a radius of curvature r which is equal to 0 (the rest of the stabilizing surface is flat with r equal to infinity), wherein in Fig. 17B the part has a radius of curvature r which is equal to about 3 mm (the rest of the stabilizing surface has a radius of curvature r equal to about 300 mm), and where in Fig. 17C the part it comprises the entire stabilizing surface and has a radius of curvature r which is equal to about 15 mm.
