DESCRIPTION
Forehead supports for face masks
Cross reference to requests
This application claims the benefit of US Provisional Applications No. 60 / 643,113, filed January 12, 2005, 60 / 696,502, filed July 6, 2005, 60 / 715,173, filed September 9, 2005 and 60 / 735,823, filed on November 14, 2005.
Field of the invention
The present invention relates generally to the field of headgear for face masks used to deliver breathing gas to the airways of a user.
Background of the invention
Face masks are well known for use in continuous positive airway pressure (CPAP) treatment of various respiratory diseases and sleep breathing disorders (SDB), such as, for example, obstructive sleep apnea (OSA) and / or other ventilatory support treatments such as noninvasive positive pressure ventilation (NPPV). See, for example, US Pat. No. 4,944,310, the entire contents of which are expressly incorporated herein by reference. Although the present invention will be described below with reference to a full face mask for use in CPAP treatment, it will be understood that such reference is not limiting and is directed toward a particularly preferred embodiment of the present invention. Thus, the various features and advantages of the present invention could be equivalently embodied in another type of mask, such as a nasal mask, or in another type of non-invasive ventilation treatment.
Document US 2004/0255949 describes a respirator arrangement for introduction of a respiratory gas for a patient and further a forehead support device for the same.
WO 00/78384 describes a forehead support adapted to be secured to a respiratory mask.
An SDB treatment apparatus generally involves a blower that delivers a positive pressure air supply to a patient interface through a conduit. The patient interface can take different forms, such as a nasal mask assembly and a nasal and mouth mask assembly (ie, a full face mask). Patients typically wear a mask set while they sleep to receive NPPV therapy.
Mask assemblies typically include a rigid shell or frame and a soft face-contact cushion. The cushion cushions the rigid frame of the patient's face and provides a seal with the patient's face. The shell and cushion define a cavity that receives the nose or nose and mouth. The frame and cushion are held in position on the patient's face by a harness assembly. The harness assembly typically comprises an arrangement of straps that run along both sides of the patient's face and the back or crown of the patient's head.
One problem that arises with existing masks used for CPAP treatments is that tightening of the mask straps causes compression of the mask against the wearer's face which can therefore apply undue force against certain facial features of the wearer, such as the user's nose. A loosely fitted mask can leak when pressurized which encourages a patient to overtighten the headgear straps which, in turn, leads to discomfort, facial marks and in some cases facial sores.
In this way, conventional masks have been provided with a forehead support, which provides a support and stability mechanism between the mask and the forehead. The forehead support both prevents the mask from being pushed too strongly against the wearer's facial region as well as minimizing the movement of the mask with the addition of a point of contact between the mask and the wearer's head thereby reducing the points pressure pressure. In addition, in face masks having a gusseted face cushion as described in copending US Provisional Patent Application Serial No. 60 / 643,113, filed January 12, 2005, a support may be employed. head-on to control the amount of bellows opening and / or closing thereby assisting the force applied to the wearer's face, eg, the patient's nasal region.
Typically, a mask forehead support is adjustable so that a standard mask may be capable of adequate fit for a number of patients with different anthropometric features. Conventional masks having adjustable forehead supports are evidenced by US Patent Nos. 6,119,693; 6,463,931; 6,557,556; and 6,691,708. To facilitate adjustment, conventional forehead supports may also be capable of displacement relative to the mask as shown, for example, in US Patent No.
IS 2 572 167 T3
6,532,961, to provide a means by which the relative angle between the mask and the forehead support can be varied to accommodate the facial features of a particular wearer.
A problem with conventional face mask supports, however, is that the range of adjustment is relatively limited which therefore does not in fact provide a universal fit for a relatively large number of users. That is, due to the anthropometric features of a particular wearer's head, the adjustment of conventional forehead supports may not be sufficient to allow a comfortable fit. Thus, while the forehead supports described above perform satisfactorily, improvements to the forehead supports for masks are needed.
Compendium of the invention
As defined by the appended claims, a mask forehead support provides greater universality of fit compared to conventional forehead support structures. More specifically, according to particular embodiments, forehead supports are provided that are capable of a more useful and beneficial adjustment range compared to conventional forehead support structures thereby allowing the forehead supports of the present invention to more universally adapt to a much larger number of patients.

Detailed description of the invention
I. First illustrated embodiment for forehead support
An exemplary embodiment of a full face mask assembly ("FMA") that includes a forehead support 10 in accordance with one embodiment of the present invention is depicted in the accompanying FIGURES 1-1 through 1-4. The FMA includes a mask frame 12 provided with a connection port 14 to which an elbow connector (not shown) associated with a gas supply conduit can be attached to allow gas under pressure to be supplied to the FMA. A facial cushion 16 is attached to a rear portion of the mask frame 12 to cushion the FMA against the wearer's face. Strap connectors 18 extend laterally from mask frame 12 to allow attachment of straps associated with a conventional headgear assembly (not shown) and thereby allow the FMA to be secured to a wearer's head when in use. .
A. Slide bar
In accordance with the present invention, mask frame 12 includes a receiver 20 that defines a channel 20-1 (see FIGURE 1-4) that is sized and configured to slidably receive an arcuate slide bar 22 therein. The bar Slider 22 includes a series of transverse openings (a few representatives of which are identified by reference numeral 22-1) that are spaced apart from each other in the general longitudinal direction of slider bar 22. The slide bar 22 includes 2-9 transverse openings 22-1 and preferably about 7-8 transverse openings 22-1. Apertures 22-1 are adapted to receive a locating pin 24 associated with receiver 20 and thereby establish a respective position of slide bar 22 relative to mask frame 12.
B. Front Cushion Support Plate
The distal end of slide bar 22 is pivotally connected to a generally V-shaped forehead cushion support plate 26 carrying a pair of forehead cushions 28 for placement against the forehead region of a user. The cushions 28 depicted in FIGS. 1-1 through 1-4 are hollow structures having a cushion surface curved essentially convexly to the forehead of the patient. The cushions are detachably attached by the support plates 26 by means of retention clips 26-1 (FIGURES 1-3, 1-4 and 5) of the same that extend into the hollow of the cushions 28 and therefore positionally retain the cushions 28 against their respective support plate 26.
As perhaps best depicted in FIGURE 1-4, support plate 26 is coupled to the distal end of slide bar 22 by means of a pivot pin 30 or other arrangement (eg, slide, ball joint, etc.) that allows movement to occur between them as shown by arrows A1. Also, since slide bar 22 is itself arcuately formed, its arcuate slide movement between a retracted position (shown generally in solid line in FIGURES 1-4) and an extended position (shown generally in FIGS. dashed line in FIGURE 1-4) as shown by arrows A2 allows cushion support plate 26 to be positioned in various angular orientations relative to mask frame 12. The pivotal movement of the cushion support frame 26 thereby enables the forehead cushions 28 to be placed flat against the forehead of a user. In such a way, therefore, the forehead support 10 can be adjustable over a wide range of dimensions and angular orientations to suit various facial profiles of a user. The amount of pivotal movement in a clockwise direction as seen in FIGURE 14 is limited by abutment surface 27 formed at the distal end of slide bar 22. In the example of FIGURE 1-4, the Plate 26 can pivot through a range of 90 ° (and preferably about 10 ° -50 ° or more or less) relative to slide bar 22.
C. Adjustment range
The universality and wide range of adjustments achieved by the front support 10 according to the present invention is graphically represented in the attached FIGURE 2. In order to better understand the advantages of the present invention, a coordinate system is defined with respect to the facial profile of a patient. When a patient is sitting upright, the x-axis is horizontal, the y-axis is vertical, and the z-axis is in the plane of the face (that is, to the left as seen from FIGURE 1-4). The CRp path of travel for a prior art forehead support is graphically depicted in FIGURE 2. With this support, some patients may end up with the forehead pads positioned at or above the hairline. In contrast, the front mount 10 of one embodiment of the present invention provides a generally more suitable range of relative motion in the z-direction as graphically represented by the circular range of designated travel CRi shown in FIGURE 2.
According to one embodiment of the present invention, a target window TW is defined for the forehead pads 28 in the ze and directions. The target window TW has upper and lower limits (y-axis), as well as inner limits and
ES 2 572 167 T3 exterior (z axis). Window has been determined based on anthropometric data from a range of sources including Head and Face Anthropometry, Leslie Farkas, Raven Press NY, NY 1994. From these data, mean and standard deviations were determined. for the hairline, glabella (the soft prominence on the forehead between the eyebrows and just above the nose) and the position of the forehead. The target window TW for the front support 10 according to the present invention can therefore be defined as follows:
(i) the upper limit of the Y axis (Yu) is the mean hairline minus two standard deviations minus 15mm;
(ii) the lower limit of the y-axis (Yl) is 15 mm above the middle glabella (G);
(iii) the interior limit of the z-axis (Z,) is half the cushion-bellows travel (GT) plus two standard deviations from the mid-front position;
(iv) the outer limit of the z axis (Zo) is the mean front position minus two standard deviations, minus half the cushion-bellows travel (GT);
Advantageously, the cushion-bellows travel (GT) ranges from about 20 to about 40 mm, preferably around 30 mm (the bellows has about 16 mm of travel and the cushion membrane has about 15 mm of travel, for therefore together with the cushion-bellows travel is around 30 mm). With a coordinate system with the zero point substantially superimposed on the nasion (N) of a patient, the middle hairline is between about 60 to about 70 mm, the middle glabella is about 10 mm, and the front position mean ranges from about -2 to about +2 in the z direction within the target window.
In accordance with especially preferred embodiments of the invention, the target window TW, also known as a target plane, which can be assumed by the forehead pads by virtue of their pivotal connection with the distal end of the slide bar 22 and the range or arcuate movement provided by the adjustable placement of slide bar 22 within receiver 20 is preferably an area limited by the following points and, Approximate z (+/-) of a coordinate system depicted in FIGURE 2 (ie, with the zero point lying substantially coincident with a region of a patient's nasion): 37.28; 30.20; 30, -22 and 37, -22.
In order for the front support 10 to achieve the required movement, the arc of the slide bar 22 (and the corresponding channel 20-1 of the receiver 20) establishes the generatrices of a circle that has a radius of about 35-70 mm and most preferably in the range of about 50-60mm. In this example, the radius is around 54mm (+/- 2mm).
D. Alternative realization of the slide bar subassembly
The accompanying FIGURES 3-1 through 3-8 show various views of an alternative embodiment of a slide bar subassembly that may be used in the face mask assembly of the present invention depicted in FIGURES 1-1 through 1-4. In this regard, the embodiment of the slide bar subassembly depicted in FIGURES 3-1 to 3-8 differs primarily from the embodiment of the slide bar subassembly discussed previously in the structural features of the front cushion support plates 50 and the front cushions 52 carried by them. Thus, compared to the general V-shaped support plates 26, the support plates 50 depicted in FIGS. 3-1 through 3-8 extend generally transversely of the slide bar 22 and are thus more shaped. usually from T.
More specifically, the support plates 50 include a relatively narrow width medial end 50-1 and a relatively larger width lateral end 50-2. Medial ends 50-1 are attached to a central support 54 which in turn is pivotally attached to slide bar 22 via pivot pin 56. In this way, the support plates 50 and the cushions 52 carried by them are capable of pivotal movements relative to the slide bar 22 about a pivot axis defined by the pivot pin 56 so that the cushions 52 can assume a range of angular positions relative to the patient's forehead. As perhaps best shown in FIGURES 3-2 and 3-4, the support plates 50 are gently curved to more closely shape the contour of a patient's forehead. If desired, the front cushion supports 50 can be attached to straps associated with a harness assembly (not shown) by inserting such straps through slots 58 defined in side ends 50-2 thereof.
The cushions 52 are generally conformably shaped to the support plates 50. The inner surfaces 52-1 of the cushions 52 have a general "concave" contour and thus are adapted to be conformably shaped relative to the forehead profile. of a patient. Each cushion 52 has a joining head 52-2 projecting rearwardly therefrom which inserts into and through a respective opening (not shown) formed in the support plates 50 to physically attach the pads 52 to the support plates. fifty. The 52-2 binding head is attached to the back of the cushion via a 52-3 flexible accordion style connector that serves to allow compatible movement of the cushions 50 so that they can be comfortably placed in contact with the forehead of the patient. The cushions 52 are more preferably attached to one another with a one-piece bridge 52-4.
In another variant, the forehead pads can take the form of a single element that extends over the upper "T" of the forehead support. In still another variant, the front support may have the form of a lower box "l",
ES 2 572 167 T3 instead of being T-shaped. In this variant, the upper part of the slide bar would include the slots 58 to directly receive the harness straps, in which case the folded parts of the harness straps could hook the patient's forehead, thereby making the forehead pads unnecessary.
E. Mask frame
As previously noted, slide bar 22 is sized and configured to be slidably received within an adaptively formed channel 20-1 formed in receiver 20 associated with mask frame 12. FIGURES 4-1 through 4-6 The annexes depict in greater detail an embodiment of the mask frame 12 that can be used with the FMA shown in FIGS. 1-1 to 1-4 previously discussed. In this regard, the mask frame 12 includes a receiver 20 which as previously discussed is a component part of the forehead support 10 in accordance with the present invention as it receives the slide bar 22. The receiver 20 is mounted toward the upper extension of the mask frame 12 and is preferably formed as a unitary molded structure (one piece) therewith. Channel 20-1 defined by receiver 20 is itself arcuately formed to match the arcuate shape of slider 22 it receives.
Receiver 20 includes a pair of opposing openings 60 through which plug 24 can be inserted when aligned with a respective one of slide openings 22-1. In this manner, when one of the apertures 22-1 is aligned with the apertures 60, the pin 24 can be inserted through it to hold the slide 22 in the position established by the selected aperture 22-1.
A plurality of vents 64 that penetrate the mask frame 12 to its interior surface (see FIGURE 4-5) may be provided to allow ventilation of the interior of the FMA and prevent accumulation of gas exhaled by the patient (eg, carbon dioxide. ).
The cushion support plate 26 which can be used in accordance with the front support 10 shown in FIGS. 1-1 to 1-4 according to the present invention is depicted in greater detail in the accompanying FIGURE 5. In this regard, support plate 26 includes a pair of retaining clips 26-1 to retain cushions 28 to plates 26 in the manner previously described. Plates 26 also define at their terminal ends a slot 26-2 to receive a strap associated with a conventional harness assembly (not shown) as may be desired. A pair of parallel edge channels 26-3 is provided to accept the respective side edges of cushion 28.
F. Alternative shape of a forehead cushion
An alternative form of a forehead cushion 70 that can be used with the support plates 26 for the forehead supports 10 in accordance with the present invention is depicted in FIGS. 6-1 through 6-2. Specifically, the forehead cushion 70 includes a generally concave cushion rim 72 that more preferably defines the generatrices of a cylindrical surface. The cushion rim 72 is supported by a cushion body portion 74 having an open channel 76 therethrough and a pair of rearwardly projecting elongated foot pads 78. The open channel 76 is sized and configured to accept in the same retaining clips 26-1 to retain cushion 70 against support plate 26. On the other hand, elongated foot pads 78 are sized and configured to be accepted in channels 26-3.
G. Alternative forms of sliding elements
Alternative forms of slide members 22A, 22B, and 22C that may be employed in the front support 10 of the present invention are depicted in FIGS. 7-1 through 7-3, respectively. In this regard, the slider 22A shown in FIGURE 7-1 is molded to have a side wall 22A1 that extends along a center line of a perimeter wall 22A2. The individual opening walls 22A3 define each of the individual position openings 22-1 while a single opening wall defines the opening 22-2 adapted to receive the pivot pin 30. The slide bar 22B shown in FIGURE 7- 2 includes connecting channels 22-3 connecting adjacent ones of position openings 22-1. The connecting channels 22-3 serve to allow a narrow diameter portion of the plug 24 to be accepted therein so that the slide bar 22b can be moved within the receiver 20 without the need to completely remove the plug 24. From In a similar manner, slide bar 22C includes an inlet channel 22-4 to allow slide bar 22 to be snapped onto pin 24. An inlet channel 22-5 is similarly provided with opening 22-2 to allow it to be snapped onto pivot pin 30. Inlet channels 22-4, 22-5 and connecting channels 22-3 They can be formed using a manufacturing method, eg laser cutting, in which a continuous path is cut to form the channels and openings.
II. Second illustrated embodiment of front support
The accompanying FIGURES 8-1 to 8-5 depict an FMA provided with another embodiment of a face support 10A in accordance with the present invention. FIGURES 9-1 through 9-6 and FIGURES 10-1 through 10-5 depict in greater detail a slide bar 122 and a mask frame 112 that can be used in the forehead support 10A. In this regard, structural components that are similar to those previously discussed have been shown by the same reference numerals. Thus, a detailed discussion of such similar structural components will not be repeated.
IS 2 572 167 T3
A. Slide bar
Front support 10A generally comprises a receiver 120 defining an arcuately formed channel 120-1 (see FIGS. 10-5) for receiving a corresponding arcuately formed slide bar 122. As perhaps best shown in FIGURES 9-1 through 9-6, slide bar 122 includes at its distal end a connector portion 126 that defines an opening 126-1 to receive pivot pin 30 (see FIGURE 8- 3). The pivot pin 30 thus serves to pivotably attach the central support 54 (see FIGURE 8-5) of the front cushion support plates 50 to the distal end of the slide bar 122 and allow for This pivot movements of the first relative to the second.
B. Adjustment knob
An adjustment knob 150 (see FIGURE 11-1) operatively carried at a distal end of receiver 120. As will be discussed in greater detail below, adjustment knob 150 is capable of being manually turned in both clockwise directions. as well as counterclockwise to adjust the position of the slide bar 122 between its retracted and extended positions. As shown more clearly in FIGS. 11-1 through 11-3, the adjustment knob 150 includes an upper head portion 152 and a lower pinion gear 154. The head portion 152 and pinion gear 154 are connected one to another by a cylindrical post member 156. Post member 156 is positioned in aperture 157 of receiver 120 so that pinion gear 154 can operatively engage gear rack 130 of slide bar 122.
As shown in FIGS. 9-1 through 9-6, slide bar 122 defines a central elongated slot 128 that extends from near its proximal end to near its distal end. Slot 128 is provided with an enlarged diameter portion 128-1 near the proximal end that is dimensioned to allow pinion gear 154 of adjusting knob 150 to pass through and thereby allow slide bar 122 to be mounted inside receiver 120. A gear rack 130 is provided on a lower face of slide bar 122 that extends substantially the entire length of slot 128 on a lateral side thereof. Gear rack 130 meshes with pinion gear 154 of adjusting knob 150. In this manner, when the adjustment knob 150 is turned in a clockwise direction as viewed from the front of the FMA, the slide bar 122 will move adjustably toward its extended position (i.e., in a clockwise direction). front of a patient). Conversely, when the adjustment knob 150 is turned in a counterclockwise direction as viewed from the front of the FMA, the slide bar 122 will move adjustably toward its retracted position (i.e., in a direction away from the FMA). the patient's forehead). Receiver 120 includes a circular raised bearing surface 153 (see FIGS. 10-1, 10-3, and 10-4) that abuts against head portion 152 of adjustment knob 150. In an alternative embodiment, a setting knob is provided that is tightened by turning counterclockwise.
C. Retention assembly
The slide bar 122 includes a resilient detent button 132 carried at the end of a resilient arm 134. The detent button 132 is adapted to be received within respective of position openings 136 provided along an edge region. side of receiver 120 (see FIGURES 10-1 through 10-5). As slide bar 122 is moved between its extended and retracted positions within channel 120-1 by twisting motions applied to adjustment knob 150 (FIGURE 11-1), detent button 132 (FIGURE 9-5) is it will resiliently and sequentially move in and out of engagement with the position openings 136 (FIGURE 10-1). Thus, the latch button 132 will fit within one of the openings 136 to aid in holding the slide bar 122 (FIGURE 8-5) in the desired position. However, the rotary motion applied to adjustment knob 150 will cause detent button 132 to be resiliently disengaged from opening 136 by arm 134 to allow sliding movement of slide bar 122 until the next opening 136 is disengaged. aligns with the button, whereby the button snaps back into it.
As shown in FIGURES 10-2 and 10-5, receiver 120 includes a plug 140 that extends into channel 120-1. Pin 140 acts as an end stop to prevent slide bar 122 from wrapping all the way to the end of gear rack 130. Pin 140 is cantilevered to provide a detent release to allow complete removal of slide bar 122 of channel 120-1.
III. Third illustrated embodiment of front support
The accompanying FIGURES 12-1 to 12-6 depict an FMA provided with another embodiment of a front support 10B in accordance with the present invention. FIGURES 13-1 and 13-7 and FIGURES 14-1 through 14-3 depict in greater detail a slide bar 322 and an adjustment knob 350 that can be used on the front bracket 10B. In this regard, structural components that are similar to those previously discussed have been shown by the same reference numerals. Thus, a detailed discussion of such similar structural components will not be repeated.
IS 2 572 167 T3
A. Slide bar
Front support 10B generally comprises a receiver 320 defining an arcuately formed channel 320-1 (see FIGURE 12-5) for receiving a corresponding arcuately formed slide bar 322. As perhaps best shown in FIGURES 13-1 through 13-7, the distal end of slide bar 322 is attached to center support 355 (FIGURE 12-1) of front cushion support plates 351. The distal end can be attached to the central support 355 in any suitable manner, eg, fixedly.
B. Adjustment knob
An adjustment knob 350 is operatively carried at a distal end of receiver 320. Adjustment knob 350 is capable of being manually turned in both clockwise and counterclockwise directions to adjust the position of slide bar 322 between its positions. retracted and extended. As shown more clearly in FIGURES 14-1 through 14-3, the adjustment knob 350 includes an upper head portion 352 and a lower pinion gear 354. Head portion 352 and pinion gear 354 are connected to each other by a cylindrical post member 356. Cylindrical post member 356 is positioned in an opening in receiver 320 so that pinion gear 354 can operatively engage the rack. gear 330 from slide bar 322. Also, adjustment knob 350 includes a bearing portion 353 that is adapted to engage receiver 320 with a press fit. The support portion 353 provides a robust connection between the mask frame and the adjustment knob 350 thereby reducing the potential play that will affect the proper operation of the zipper 330.
As shown in FIGURES 13-1 through 13-7, slide bar 322 defines a central elongated slot 328 that extends from near its proximal end to near its distal end. The slot 328 is provided with an enlarged diameter portion 328-1 near the proximal end which is dimensioned to allow the pinion gear 354 of the adjusting knob 350 to pass through and thus allow the slide bar 322 be mounted inside receiver 320. A gear rack 330 is provided on a lower face of slide bar 322 that extends substantially the entire length of slot 328 on a lateral side thereof. Gear rack 330 meshes with pinion gear 354 of adjusting knob 350. In this manner, when the adjustment knob 350 is rotated in a clockwise direction as viewed from the front of the FMA, the slide bar 322 will move adjustably toward its extended position (that is, in one direction). upward direction. forehead of a patient). Conversely, when the adjustment knob 350 is turned in a counterclockwise direction as viewed from the front of the FMA, the slide bar 322 will move adjustably toward its retracted position (that is, in a direction away from the patient's forehead). However, the direction of movement of the slide bar as the adjustment knob is turned clockwise can be designed to extend or retract by moving the gear rack on the other side of the slide bar. In this way, the direction of rotation of the adjustment knob can be interchanged, for example a clockwise movement could extend or retract the slide bar.
C. Helical teeth in gear rack and / or pinion gear
In this embodiment, at least one of the gear rack 330 of the slide bar 322 and the pinion gear 354 of the adjustment knob 350 is a helical gear that includes helical teeth, that is, a gear that has teeth cut at an angle. toward the gear face. The use of helical teeth in at least one of the rack 330 and pinion gear 354 provides an automatic locking feature so that the gear rack 330 and pinion gear 354 will not move when force is applied from either the forehead support or mask. That is, the helical teeth are configured so that the adjustment knob 350 can easily move the slide bar 322, but the slide bar 322 cannot move the adjustment knob 350. This arrangement prevents inadvertent movement of the front bracket during its operation. use. Also, because gears 330, 354 provide an automatic locking feature, a detent button on slide bar 322 and position openings on receiver 320 are not required.
In the illustrated embodiment, gear rack 330 includes helical teeth having a 40 degree helix angle and pinion gear 354 includes a 20 degree helix angle and the pinion has a 20 degree helix angle to the gear rack. 330 (see Fig. 12-2). The 20 degree helix on the pinion and the 20 degree angle of the pinion to the rack cause the 40 degree gear rack helix angle. However, the pinion gear 354 can be angled 20 degrees in the other direction (ie, counterclockwise) to improve the angle of the adjustment knob 350 relative to the patient and therefore easy to adjust. Also, the teeth of gears 330, 354 may be at any other suitable angle, eg, 10 to 40 degrees, to provide the self-locking feature.
Additionally, there are other potential design options to provide the auto-lock feature. For example, helical teeth may be provided on gear rack 330 only, helical teeth may be provided on gear rack 330 with angled teeth on pinion gear 354, or straight teeth may be provided on gear rack. 330 with angled teeth on 354 pinion gear. All of these options will help lock the gear rack 330 and pinion gear 354 when force is applied from either the forehead mount or the mask.
IS 2 572 167 T3
IV. Front support friction lock
In an alternative embodiment, the gear rack and pinion gear can be designed so that sufficient friction is provided to lock the slide bar in position when in use. This arrangement prevents the gear rack and gear from moving when a force is applied either from the forehead support or from the mask. This friction can be achieved through the use of surface texture, particular materials, and / or a reduction in backlash between gear teeth.
V. Fourth illustrated embodiment of front support
The accompanying FIGURES 15-1 to 15-8 depict an FMA provided with another embodiment of a face support 10C in accordance with the present invention. FIGURES 16-1 through 16-7, FIGURES 17-1 through 17-7, and FIGURES 18-1 through 18-5 depict in greater detail a slide bar 422, a mask frame 412, and an adjustment knob 450 that they can be used on the front support 10C. In this regard, structural components that are similar to those previously discussed have been shown by the same reference numerals. Thus, a detailed discussion of such similar structural components will not be repeated. It is noted that the mask frame 412 includes connecting structures 418 that are adapted to connect with the headgear loops associated with a headgear assembly.
A. Slide bar
Front support 10C generally comprises a receiver 420 defining an arcuately formed channel 420-1 (see FIGURE 17-6) for receiving a corresponding arcuately formed slide bar 422. As illustrated, the receiver 420 is relatively stronger and wider to provide more support to the front support and to avoid any cracking or fracturing. As perhaps best shown in FIGS. 16-1 through 16-7, the distal end of the slide bar 422 is attached to the center support 455 of the front cushion support plates 451. In the illustrated embodiment, the front support it does not have a hinge, which causes the angle of the pad against the forehead to change about 20 degrees with movement of the slide bar 422. This arrangement helps keep the pad flat against the forehead. However, slide bar 422 may be attached to center bracket 455 in any other suitable manner, for example, through a pivot pin.
B. Adjustment knob
An adjustment knob 450 is operatively carried on a distal end of receiver 420. Adjustment knob 450 is capable of being manually rotated in both clockwise and counterclockwise directions to adjust the position of slide bar 422 between its positions. retracted and extended. As shown more clearly in FIGS. 18-1 through 18-5, the adjustment knob 450 includes an upper head portion 452 and a lower pinion gear 454. Head portion 452 and pinion gear 454 are connected to each other by a cylindrical post member 456. Post member 456 extends through aperture 457 of receiver 420 so that pinion gear 454 can engage operatively the gear rack 430 of the slide bar 422. Specifically, the receiver 420 provides ramp portions 431 adjacent to the opening 457. Ramped portions 431 assist with mounting so that post member 456 can engage within aperture 457 with a press fit. Ramp parts 431 also provide projections to prevent easy disassembly. Also, the receiver includes an elongated strain relief opening 433 adjacent to opening 457. Opening 433 allows opposing arms of receiver 420 to open to accommodate adjustment knob 450 within opening 457. As illustrated, the upper head portion 452 has a gear-like configuration around its perimeter to provide a tactile grip.
As shown in FIGS. 16-1 through 16-7, a gear rack 430 is provided on an upper surface of slide bar 422 extending substantially the entire length thereof. Gear rack 430 meshes with pinion gear 454 of adjusting knob 450. In this manner, when the adjustment knob 450 is rotated in a counterclockwise direction as viewed from the front of the FMA, the slide bar 422 will move adjustably toward its extended position (i.e., in a direction toward the left). front of a patient). Conversely, when the adjustment knob 450 is turned in a clockwise direction as viewed from the front of the FMA, the slide bar 422 will move adjustably toward its retracted position (i.e., in a direction away from the patient's forehead). As illustrated, substantially large teeth are provided on gears 430, 454 to improve design robustness.
C. Retention assembly
In this embodiment, a retention assembly is provided in order to provide tactile feedback to the movement of slide bar 422. In the illustrated embodiment, the retention assembly is provided by raised triangular position markers 432 on receiver 420 that interact with openings 436 in adjusting knob 450. As the adjustment knob 450 is turned to extend or retract the slide bar 422, the raised triangular position markers 432 will move in and out of engagement with the openings 436 provided in the adjustment knob 450. Thus, the markers Raised triangular locator pins 432 will snap into respective openings 436 to assist in braking the slide bar 422 into position.
ES 2 572 167 T3 desired. However, a twisting motion applied to the adjustment knob 450 will cause the raised triangular position markers 432 to be resiliently disengaged from the respective apertures 436 to allow sliding movement of the slide bar 422 until subsequent apertures 436 align. with the raised triangular position markers 432, whereby the raised triangular position markers 432 snap back into them. This restraint assembly provides the user with a means of measuring the amount of adjustment one makes to the front support position.
The spacing of the apertures 436 may or may not be aligned to provide feedback that corresponds to the position of the gear teeth. Also, the retention assembly can be structured to provide a locking feature.
SAW. Position marks on front support
In one embodiment, position marks may be provided on the adjustment knob 150, 350, 450 and / or the slide bar 122, 322, 422 to indicate the position of the front bracket. For example, as shown in FIGURE 19-1, numbers may be provided on an adjustment knob 550 that align with a position arrow 551 provided on receiver 520 to indicate the front support position. As illustrated, the numbers range from 1-13. In embodiments, the numbers can range from a minimum of 1-4 to a maximum of 1-30. However, any suitable range and brand can be provided on the adjustment knob. As shown in FIGURE 19-2, spaced markings 651, which can be color-coded and / or numbered, may be provided on a slide bar 622 to indicate the front support position as slide bar 622 extends. and retracts during use. However, any other suitable marking may be provided on the slide bar.
VII. Adjustment knob cover
In a further embodiment, the adjustment knob 150, 350, 450 may have a cap that provides a surface that can be used for marking, instructions, and / or labeling of locations, for example.
VIII. Variable rate of forward support movement
In yet another embodiment, the rack and pinion gear described above can be configured to provide a variable rate of movement of the slide bar. That is, the rack and pinion gear can be configured to provide a finer adjustment throughout parts of the range of motion and a coarser adjustment throughout other parts of the range of motion. For example, as shown in FIGURE 20-1, the gear rack 730 can be configured so that finer adjustment, eg, slower movement, of the front support position can be provided by rotation of the adjustment knob at the extremes of the range of motion as an indication that the extremes of motion have been reached. In an alternative embodiment, as shown in FIGURE 20-2, a gear rack 830 can be configured so that a finer adjustment of the front support position by rotation of the adjustment knob can be provided in the middle of the gear. range of motion to provide fine control in the position where most patients will attach the support head-on.
IX. Alternative design goal
In the forehead supports 10B and 10C embodiments, the design target for the center of the forehead pad is a substantially straight line defined by the line tL in FIGURE 21. The end points of the line TL have the coordinates ( 40.3, -13.7, 40.3, 16.9). Generally, the TL line can be described as a 30mm horizontal distance allowing around 15mm of slack between the bottom of a forehead pad (assuming the pad is around 28mm high) and G ( Glabella).
The horizontal coordinates are calculated from the intersection of the height of 40.3 mm with a line drawn from G to FB (the most forward position in the measurement of the mean hairline minus two standard deviations) and G to FD (the furthest forehead position in the mid hairline measurement minus two standard deviations) plus 7.5mm of travel on either side. While the objective in these embodiments is a horizontal line, the movement of the front support will be arcuate due to its construction.

IS 2 572 167 T3
A. Slide bar
The forehead support 10D generally comprises a receiver 220 attached to the mask frame 212. The receiver 220 defines an arcuately formed channel 220-1 (see FIGS. 24-5) for receiving an arcuately formed slide bar 222. correspondent. Receiver 220 also defines an elongated central slot 224 through which raised pushbutton 240 associated with slide bar 222 projects. As perhaps best shown in FIGURES 23-1 through 23-6, slide bar 222 includes at its distal end a connector portion 226 that defines an opening 246-1 to receive pivot pin 30 (see FIGURE 22- 3). The pivot pin 30 thus serves to pivotally attach the central support 54 of the front cushion support plates 50 to the distal end of the slide bar 222 and thereby allow pivotal movements of the first relative to the second. In an alternative embodiment, the central support can be rigidly connected to the distal end of the slide bar.
B. Receiver with ratchet teeth
Receiver 220 includes a series of paired ratcheting teeth 230 protruding into channel 220-1 (FIGURE 24-5) along the lateral sides of central slot 224 (see FIGURES 24-2 and 24-5). from the proximal end of receiver 220 to the distal end thereof. As perhaps best shown in FIGURE 24-2, the ratchet teeth 230 are angled in a generally downward direction when the mask frame 212 is in a vertical state.
C. Slider bar tongue element
As shown in FIGS. 23-1 through 23-5, a pair of elongated parallel grooves 242 is provided near the respective lateral sides of slide bar 222. The grooves 242 extend substantially one-quarter to about a middle of the slide. circular distance of arcuate slide bar 222 beginning at the distal end thereof to establish a resilient central tab member 244. Tongue element 240 also carries a pair of fixed engagement pawls 248 that are sized and configured to engage with a respective pair of pawl teeth 230 of receiver 220.
In use, the slide bar 222, and thus the forehead cushions 52 carried by it, can be positionally adjusted to assume a desired position by pressing against the pushbutton 240. The pressure against the pushbutton 240 thereby causes the resilient tab 244 to be flexed downward to release an engagement between the pawls 248 and a pair of the pawl teeth 230. As pawls 248 and teeth 230 disengage, therefore, slide bar 222 can be slid along channel 220-1 of receiver 220 between its retracted and extended positions to assume a desired position. Upon reaching such a desired position, the pushbutton 240 can be released which returns the resilient tab 244 to its normal state thereby bringing the pawls 248 into engagement with another pair of pawl teeth 230.
It should be understood that other suitable mechanisms may be used to secure the slide bar relative to the receiver. For example, the slide bar can be secured with respect to the receiver by, for example, a fixation such as a screw, friction, etc. Also, the slide bar can be attached to the receiver by a loose pivoting arrangement or a spring arrangement.
XI. Spiral screw mechanism
FIG. 25 schematically illustrates a coil screw mechanism 1020 in accordance with one embodiment of the present invention. The coil screw mechanism 1020 can be used in a face mount of an FMA such as those discussed above.
As illustrated, the spiral screw mechanism 1020 includes a knob 1050 with a number of pins 1052 (or spiral ribs) and a strap 1022 with a number of spirally formed grooves 1030. The pins 1052 of the knob 1050 are adapted to engage with spirally formed grooves 1030 in strap 1022. As knob 1050 is turned, pins 1052 push or pull strap 1022 toward or away from the shaft of the knob. In the flat configuration shown, the pins 1052 could potentially interfere with the strap 1022 as they rotate back over it. However, this should not be a problem if strap 1022 is curved (eg, provided in a curved receiver of the mask frame) so that strap 1022 does not reach the path of the underside of pins 1052. Advantages of this concept include simplicity, strength, and the ability to provide a pull / push force that closely aligns with the axis of the knob 1050 which reduces jamming problems with sliding action.
