    CROSS REFERENCE TO RELATED ORDERS
    This patent application claims priority benefit under 35 USC § 119 (e) of North American Provisional Application No. 61 / 378,103 filed on August 30, 2010, the content of which is incorporated herein by reference. HISTORY OF THE INVENTION FIELD OF THE INVENTION
    The present invention relates to patient interface devices for transporting a gas to and / or an airway of a user and, in particular, to a patient interface device with a frame assembly that includes a frame support with a double Y configuration. DESCRIPTION OF RELATED TECHNIQUE
    There are numerous situations in which it is necessary or desirable to distribute a flow of breathing gas non-invasively to a patient's airways, that is, without intubating the patient or surgically inserting an endotracheal tube into his esophagus. For example, ventilation of a patient is known using a technique known as noninvasive ventilation. The distribution of continuous positive airway pressure (CPAP) or variable airway pressure, which varies according to the patient's respiratory cycle, is also known for the treatment of a medical disorder, such as syndrome sleep apnea, in particular, obstructive sleep apnea (OSA) or congestive heart failure.
    Noninvasive ventilation and pressure support therapies involve placing a patient interface device that includes a mask component on a patient's face. The mask component can be, among others, a nasal mask that covers the patient's nose, a nasal pad with nasal pins that are received in the patient's nostrils, a nasal / oral mask that covers the nose and mouth or a mask of entire face covering the patient's face. The patient interface device interfaces between the ventilator or pressure support device and the patient's airway, so that a flow of breathing gas can be delivered from the pressure / flow generating device to the airway. of the patient. It is known to maintain said devices on the user's face by a head support with one or more straps adapted to fit / around the patient's head.
    Patients in need of pressure support therapy are often faced with the problem of finding a suitable patient interface device. Upon finding a suitable patient interface device, said patients generally have difficulties with the problems related to the sealing and stability of the patient interface device, the comfort of the patient interface device, the size / weight of the interface device and the design of the patient interface device. These challenges, if not treated properly, can compromise the patient's compliance with the prescribed therapy.
    More specifically, during the night, the stability of a mask seal will be challenged by the patient who moves in his bed. Changing the position of the head can lead to torque in the air distribution hose and general interference with other objects (for example, pillows, sheets, blankets, etc.). Thus, stability and, consequently, sealing, is a challenge for any patient interface device on the market.
    In addition, patient comfort is an important factor, and can be negatively affected in many ways. For example, over-tightening the 5-head support (to compensate for the lack of sealing and stability) can increase pressure on the face and head, which in turn can result in pressure points and / or skin degradation. Other components of the patient interface device (for example, straps, frames, head supports, etc.) 10 can also generate discomfort for the patient, because the geometry of said components can conflict with the structures of the face.
    In addition, the overall weight of the patient interface device can negatively impact a patient's experience, causing additional facial pressure or causing excessive tightening problems. The weight of the patient interface device can also negatively affect sealing and stability. Some patients also have problems with a patient interface device that interferes with their line of sight, and the overall size of the patient interface device has been known to cause claustrophobia in some patients.
    Finally, properly sizing a patient interface device can be difficult, because facial structures vary greatly between patients. Not all patient interface devices are capable of accommodating this range of differences, which requires more sizes / variations or the failure to provide an ideal fit for the majority of the user population. SUMMARY OF THE INVENTION
    Thus, it is an object of the present invention to provide a patient interface device that overcomes the shortcomings of the conventional patient interface device. This objective is achieved in accordance with an embodiment of the present invention by providing a patient interface device that includes a pillow and a frame assembly coupled to the pillow, the frame assembly of which includes a main frame member and a stiffening structure coupled to the main frame member, the stiffening structure having a main arm, a first Y-portion coupled to a first end of the main arm with the first and second branches extending at upward and downward angles, respectively, from the first end of the main arm, and a second Y-portion coupled to a second end of the main arm with the first and second branches extending at upward and downward angles, respectively, from the second end of the main arm.
    In another embodiment, a frame assembly is provided for a patient interface device that includes a main frame member and a stiffening structure coupled to the main frame member, the stiffening structure having a main arm, a first Y-portion coupled to a first end of the main arm with the first and second branches extending at upward and downward angles, respectively, from the first end of the main arm and a second Y portion coupled to a second end of the main arm with the first and the second branches extending in ascending and descending angles, respectively, from the second end of the main arm.

    As used here, the singular form of "one", "one", "o" and "a" includes plural references, unless the context clearly indicates otherwise. As used here, the statement that two or more parts or components are "coupled" must mean that the parts are joined or operated together, either directly or indirectly, that is, through one or more intermediate parts or components, provided that a connection occurs. As used here, "directly coupled" means that two elements are directly in contact with each other. As used here, "fixedly coupled" or "fixed" means that two components are coupled, in order to move as one, while maintaining a constant orientation with respect to each other.
    As used here, the term "unitary" means that a component is created as a single part or unit. That is, a component that includes parts that are created separately and then coupled as a unit is not a "unitary" component or body. As used here, the statement that two or more parts or components "engage" with each other must mean that the parties exert a force against each other, either directly or through one or more intermediate parts or components. As used here, the term "number" must mean one or an integer greater than one (that is, a plurality).
    The directional phrases used here, such as, for example and among others, upper, lower, left, right, taller, lower, front, rear and their derivatives refer to the orientation of the elements shown in the drawings, and are not limited to the claims, unless expressly recited here.
    FIG. 1 is a front perspective view of a patient interface device 2 according to an exemplary embodiment of the present invention. FIG. 9 is a side view, and FIG. 10 is a front perspective view showing the patient interface device 2 attached to a patient. The patient interface device 2 includes a frame member 4 and a pad 6 coupled to the frame member 4, each of which is described in more detail here.
    FIGS. 2, 3, 4 and 5 are the front, rear, top and side elevation views, respectively, of the frame member 4 of the patient interface device 2. The frame member 4 includes a generally annular central member 8 with the first and the second main arms 10A, 10B extending outwardly from opposite sides of it. The main arm 10A includes a hole 12A that extends through it, and the main arm 10B includes a hole 12B that extends through it. In the exemplary embodiment, the holes 12B, 12A are positioned in one location on the main arm 10A, 10B adjacent to the central member 8. The purpose of the holes 12A, 12B is described in detail in this document. In addition, as seen in FIGS. 2 and 3, the central member 8 defines the central hole 14.
    The frame member 4 further includes a first branch member 16A that extends upwardly at an angle from the main arm 10A, and a first branch member 16B that extends upwardly at an angle from the main arm 10B. In a particular non-limiting embodiment, the first branch members 16A, 16B extend upwardly from the respective main arm 10A, 10B at an angle of about 60 degrees, although other angles are also possible. In addition, the frame member 4 also includes a second branch member 18A that extends downwardly at an angle from the main arm 10A, and a second branch member 18B that extends downwardly at an angle from main arm 10B. In a particular non-limiting embodiment, the second branch members 18A, 18B extend downwardly from the respective main arm 10A, 10B at an angle of about 30 degrees, although other angles are also possible. Also in a particular non-limiting embodiment, the main arms 10A and 10B extend about 55-60 mm from the center of the holes 12A, 12B to the internal angles formed between the branch members 16A and 18A and 16B and 18B, respectively.
    Furthermore, as can be seen in FIGS. 1-5, the distal end of each of the first branch member 16A, 16B and the second branch member 18A, 18B includes a respective circuit member 20 for receiving a respective strip 22 of the head support assembly 24 (FIGS 9 and 10). In the exemplary embodiment, the frame member 4 is made of a thermoplastic or thermoset material.
    FIGS. 6, 7 and 8 are the front perspective view, front elevation and rear elevation views, respectively, of pad 6 of the patient interface device 2. In the exemplary embodiment, pad 6 is defined from a unitary piece of material soft, flexible, padded elastomeric, such as, among others, silicone, a suitably soft thermoplastic elastomer, closed cell foam or any combination of said materials. Pad 6 includes a main body portion 40 that has a sealing portion 42 coupled to a first end thereof. The sealing portion 42 is structured to form a seal against the patient's face. In the illustrated embodiment, the pad 6 is in the form of a nasal mask. However, other types of patient seal sets, such as a nasal / oral mask, a nasal cannula or a nasal pillow that facilitates the distribution of the gas flow of breath to a patient's airway, can be replaced by the pillow 6 , while remaining within the scope of the present invention.
    In addition, the main body portion 40 defines orifice 44 at its second end, opposite the first end. The orifice 44 is structured to allow the cushion 6 to be hydraulically coupled to a fluid connector, such as an elbow conduit which, in turn, is hydraulically coupled to a pressure generating device, such as a fan or a machine. CPAP, through a gas distribution hose.
    Pad 6 further includes generally cylindrical columns 466A and 466B extending from the first and second sides 48A and 48B, respectively, of the main body 40. Each column 46A, 46B is positioned approximately midway between the first and the second ends of the pad 6. In addition, each column 46A, 46B includes an inner cylindrical portion 50, an enlarged portion 52 and an outer cylindrical portion 54.
    When the patient interface device 2 is mounted, the second end of the main body 40 is inserted through the central hole 14 defined by the central member 8. In addition, the column 46A is inserted through the hole 12A, and the column 46B is inserted through hole 12B. More specifically, as can be seen in FIG. 1, in each case, the outer cylindrical portion 54 and an enlarged portion 52 are inserted through respective holes 12A, 12B so that each enlarged portion 52 rests against the outer surface of the main arm 10A, 10B and prevents the cylindrical portion outer 54 slide back through hole 12A, 12B. In addition, each inner cylindrical portion 50 is capable of pivoting within the respective orifice 12A, 12B.
    The branching nature of the sides of the frame member 4, which gives it a "T" or "Y" conformation, allows the frame member 4 to flex in certain directions while at the same time limiting flexion in other directions . In particular, the main arms 10a, 10b are capable of flexing in the directions indicated by the arrows in FIG. 4 (ie, parallel 'to the upper and lower surface of the main arms 10A, 10B), but is not able to flex freely in a transverse direction in relation to its longitudinal axis (that is, perpendicular to the upper and lower surface of the main arms) 10A, 10B). In addition, each of the first branch members 16A, 16B and the second branch members 18A, 18B can flex independently of each other in the directions indicated by the arrows in FIG. 4 (that is, parallel to the upper and lower surface of the branch members), but it is not able to flex freely in a transverse direction in relation to its longitudinal axis (that is, perpendicular to the upper and lower surface of the branch members). This controlled flexion addresses several problems present in the technique already in use in relation to sealing, stability and comfort discussed in this document, since it passively accommodates many facial and head geometries to allow for optimal adjustment and comfort. The branched structure of the frame member 4 also increases the stability of the patient interface device 2 through the movement of the patient and the torque of the hose, which provides an ideal seal for the patient.
    In addition, the selection of material for the frame member 4 with the geometry of the frame member 4, as described here, allows flexion to accommodate the wide range of patient's facial structures and head dimensions. In the exemplary embodiment, the material will be soft enough to provide bending in the desired directions, as described here, but rigid enough to limit bending in unwanted directions, as described here. In addition, the geometry, in the exemplary realization, will allow the accommodation not only of the regions of the temple, cheek and jaw, but will also cover different sizes of head and locations of the nose. The geometry of the frame member 4 portions may, for example, vary in thickness, existence of ribs or other structures and / or general dimensioning to accommodate bending differences due to the material properties, but will retain the branching shape described here .
    Other alternative methods of controlling the flexing direction of the frame member 4 in the various directions can be achieved with the use of structures such as the hinges incorporated in it. The hinge can be achieved in a number of different ways, such as with mechanical interlocking (removable or permanent) or overmoulding with materials such as silicone or other 5 elastomers.
    In addition, the branching nature of the sides of the frame member 4 that gives the "T" or "Y" conformation discussed above moves the assembly or anchor point (i.e., the circuits 20) to the interface device 10 patient 2 on the patient's head by means of a head support assembly 24 further back along the side of the head. The typical locations for fitting nasal masks have been in one or many of the following: cheeks, forehead and chin. By moving the mount point away from the front of the face, 15 it improves claustrophobia problems and the violation of line of sight. This also limits the pressure and potential discomfort of over-tightening in the less sensitive areas of the face.
    In addition, the interaction between columns 46A, 46B and 20 orifices 12A, 12B provides the connection point for from pad 6 to the frame 4. This connection point provides a passive self-adjusting mechanism for pad 6, a Since the columns 46A and 46B and thus the pad 6 are able to rotate in relation to the frame member 4. In the exemplary embodiment, each column 46A, 46B has sufficient interference with the frame member 4 to limit the rotation excessive, but not enough resistance to prevent self-adjustment. Also in the exemplary embodiment, the cylindrical conformation of each column 46A, 46B, as opposed to an oval or other geometry, allows an infinite number of positions, instead of a discrete positioning. This self-adjusting feature optimizes the engagement angle between the pad 6 and the patient's face, and increases the possibility of an ideal seal between the many faces of patients of different sizes and shapes. In addition, it reduces the chance of undue pressure along the sealing portion 42 of the pad 6 on the patient's face (in particular, the upper lip). Finally, this self-adjusting feature provides the ability of the cushion 6 to adjust during the patient's movement, thereby increasing stability throughout the night.
    Thus, the combination between the flexible frame member 4 and a. self-adjusting pad 6 allows the placement of the frame member 4 on the face to vary in order to meet the individual needs of the patient. This provides an opportunity for the patient to relieve any possible pressure points and / or optimize sealing and stability. In addition, the mounting point of the pad 6 15 on the frame member 4 has been moved closer to the patient's face, which increases the stability of the patient interface device 2 with the movement of the support point closer to the face. of the patient (the moment arm decreases). This also decreases the overall profile of the patient interface device 20, which creates a lower profile that improves the overall size and appearance.
    An alternative exemplary embodiment of the invention is shown in FIGS. 11 and 12 and includes the frame set 60 that can be attached to the cushion 6 as described here in the document or another suitable cushion, such as, among others, a known or subsequently developed nasal / oral mask, a nasal cushion, pillow style or a full face mask. The frame assembly 60 includes a frame member 4, as described in this document, with inserts provided therein or fastened (e.g., glued) to it (i.e., the outer surface) in the form of right and left stiffening structures 62A and 62B. In the exemplary non-limiting embodiment, the frame member 4 is made of a high hardness silicone, such as, among others, the LSR 75 Shore A (± 5 Shore A) durometer (liquid silicone rubber), molded into the stiffening structures right and left 62A and 62B, as shown in FIGS. 11 and 12. Also in the exemplary embodiment, the stiffening structures 62A and 62B are made of a thermoplastic material such as polycarbonate, such as HP4, although other materials, such as polypropylene, can also be used. In addition_The frame assembly 60 may have a lining fabric or other surface treatment or texture for aesthetics, patient comfort or for the absorption of moisture or heat caused by the patient.
    FIG. 13 is a side elevational view of the left stiffening structure 62B. The right stiffening structure 62A is identical in structure and symmetrical to the left stiffening structure 62B. The stiffening structures 62A and 62B each have a double Y-shaped reach, in which one of the Y portions faces the patient's ear, while the other Y portion faces the cushion attached to the frame assembly 60 (which, as discussed in this document, can be a nasal pillow, a nasal / oral mask, a pillow cushion or a full face cushion). In particular, the stiffening structures 62A and 62B each include a main arm 64 with an orifice 66, front branches 68 and 70 extending upward and downward angles, respectively, from the main arm 64, and rear branches 72 and 74 extending at ascending and descending angles, respectively, from the main arm 64.
    In the exemplary embodiment, the main body 64, the front branches 68 and 70, and the rear branches 72 and 74 each have a thickness of about 0.058 inches and a width of about 0.25 inches. In the exemplary embodiment, the main arms 10A, 10B and branch members 16A, 16B, 18A, 18B are about 0.125 inches thick and about 0.475 inches wide. The purpose of the stiffening structures 62A and 62B is to provide vertical support and stabilize the cushion 6 and preserve the patient's seal while forces are exerted on him as a result of the patient's movement (for example, hose related forces). The Y side of the mask (frontal branches 68 and 70) has a generally symmetrical conformation in relation to the AA line shown in FIGS. 12 and 13, while the Y side of the ear (rear branches 72 and 74) is asymmetric with respect to the AA line shown in FIGS. 12 and 13.
    In a particular embodiment, the portion of each stiffening structure 62A, 62B between each Y has a length (marked as li in FIG. 12) of 55-60 mm. This size is critical for positioning the Y side of the ear, so that the head support connections and the force vectors are far from the immediate region of the cushion and still negotiate around the ear region for the majority of the patient population. . The Y side of the ear has an upper limb (rear branch 72) that has a central line that is positioned at an angle α with respect to the line AA of FIG. 12 (the centerline of the main arm 64). In the illustrated embodiment, α is about 60 degrees. The lower ear member (rear branch 74) has a central line that is positioned at an angle θ with respect to the line AA in FIG. 12. In the illustrated embodiment, θ is about 30 degrees. In addition, in the illustrated embodiment, the upper limb on the Y side of the ear (rear branch 72) extends over half of the first associated branch member 16A, 16B, so that di = d2 as shown in FIG. 12. The lower limb on the Y side of the ear (rear branch 72) extends approximately the length of the first associated branch member 18A, 18B (to a point adjacent to where the circuit member 20 starts).
    FIG. 14A is a side elevation view of the stiffening structure 62B with lines indicating certain cross-sectional views of the stiffening structure 62B shown in FIGS. 14B-14G. Referring to FIGS. 14A- 14G, in the exemplary embodiment, the degree of curvature of the cross section (with reference to the longitudinal axis of the main arm 64) on the Y side of the ear (that is, both the rear branch 72 and the rear branch 74) decreases from the first end from the Y side of the ear immediately adjacent to the end of the main arm 64 to the distal end of the Y side of the ear (i.e., the distal end of both the rear branch 72 and the rear branch 74). In particular, as shown in FIGS. 14B 14G, the decrease in curvature is prescribed by the Y side of the ear with a succession of rays in cross-section Ri a Re that increase from the first end of the Y side of the ear to the distal end of the Y side of the ear (Ri <R2 <R3 <R4 <R5 <Rs) • This curvature is designed to match the contours of the human face for the majority of the patient population. In a particular embodiment, Ri = 116.85 mm, R2 = 132.59 mm, R3 = 159.51 mm, R4 = 223.23 mm, R5 = 247.66 mm and Rs = 421.98 mm.
    FIG. 15A is a side elevation view of the stiffening structure 62B with lines indicating certain cross-sectional views of the stiffening structure 62B shown in FIGS. 15B-15D. Referring to FIGS. 15A-15D, in the exemplary embodiment, the degree of curvature of the cross section (with reference to the longitudinal axis of the main arm 64) on the Y side of the mask (i.e., both front branches 68 and 70) increases from the first end of the Y side from the mask immediately adjacent to the end of the main arm 64 to the distal end of the Y side of the mask (i.e., the distal end of both the front branch 68 and the front branch 70). In particular, as shown in FIGS. 15B-15D, the increase in curvature is prescribed by the Y side of the mask with a succession of rays in cross section R7 to R9 that decrease from the first end of the Y side of the ear to the distal end of the Y side of the ear (R7> R8> R9). In a particular embodiment, R7 = 32.59 mm, R8 = 32.31 mm and R3 = 30.44 mm.
    FIG. 16A is a side elevation view of the stiffening structure 62A, and Figure 16B is a cross-sectional view of the stiffening structure 62A taken along the lines Z-Z of FIG. 16A. As seen in FIG. 16B, the main arm 64 has a curvature that is prescribed by the rays Rio, Rn and Ri2. In a particular embodiment, R10 = 181.07 mm, Rn = 1520.95 mm and R12 = 121.46 mm.
    FIG. 17 is a front perspective view of a patient interface device 102 according to another embodiment of the present invention, and FIGS. 18 and 19 are the front and side views, respectively, of a frame member 104 of the patient interface device of FIG. 17. Patient interface device 102 is generally similar to patient interface device 2 described above, with some of the differences being discussed in detail below. As in the previous embodiment, a pad 106 is attached to a frame assembly 160 that includes a frame member 104, so that the pad is movable with respect to the frame member. The frame member 104 includes a generally annular central member 103 with the first and second main arms 110A, 110B. An opening 99 is defined in the central member 103. The frame member 104 includes a first branch member 116A that extends upwardly at an angle from the main arm 110A and a first branch member 116B that extends upwardly at an angle from the main arm 110B. In a particular non-limiting embodiment, the first branch members 116A, 116B extend upwardly from the respective main arm 110A, 110B at an angle of about 63 degrees ± 5 degrees, although other angles are also possible. Note that the branch members 116A, 116B are more curved or have a more arcuate conformation than the branch members of the previous embodiments. It is believed that this curved conformation provides a frame that fits better to the anatomy of a human head.
    In addition, frame member 104 also includes a second branch member 118A that extends downwardly at an angle from main arm 110A and a second branch member 118B that extends downwardly at an angle from main arm 110B. In a particular non-limiting embodiment, the second branch members 118A, 118B extend downwardly from the respective main arm 110A, 110B at an angle of about 44 degrees ± 5 degrees, although other angles are also possible. Note that the branch members 118A, 118B are more curved or have a more arcuate conformation than the branch members of the previous embodiments. It is believed that this curved conformation provides a frame that fits better to the anatomy of a human head. The distal end of each of the first branch member 116A, 116B and the second branch member 118A, 118B includes a respective circuit member 120 for receiving a respective strip from the head support assembly 24.
    In this embodiment, the coupling of the pad 106 to the frame member is achieved by means of a coupling assembly 107 that includes a pair of protrusions 109 provided on each side of a collar 105 coupled to the pad 106. In the illustrated embodiment, at least a portion of each protrusion 109 is seated or arranged in a slot or groove 108 which is provided in the frame member 104. This arrangement allows the pad 106 to move in relation to the frame member 104, for example, with rotation about one axis defined through protrusions 10 9-, said movement allows the cushion to automatically rest on the patient when the patient interface device is worn by the user.
    In the exemplary embodiment, each main arm 110A and 110B of the frame member 104 is defined by a stiffening member 162 disposed in a flexible material. In an exemplary embodiment, the stiffening member is defined by a plastic and the flexible material is a compressed foam covered in the fabric.
