Definitions

  • Embodiments relate to a liner for use with a respiratory mask, such as a CPAP mask.
  • Obstructive sleep apnea is a serious and potentially fatal medical condition in which a person's airway becomes physically blocked multiple times during sleep, restricting oxygen intake and causing the person to awake gasping for breath. Possible effects of the condition include extreme fatigue, high blood pressure, strokes, heart attacks, and sometimes even death.
  • CPAP continuous positive airway pressure
  • CPAP masks are made from silicone, rubber, vinyl, or a nylon-based fabric. These materials are typically water and gas impermeable, which can block off pores, cause sweating, and create pressure marks on the face, increasing the discomfort of the mask. Furthermore, most mask manufacturers recommend against the use of skin or face cream with CPAP masks since the mask material directly contacts the skin. This is a problem for many users, especially those that have dry skin and depend on night cream for skin care.

  • a liner for use with a respiratory mask such as a CPAP mask M (see FIG. 5) is illustrated and designated generally by reference numeral 10.
  • the liner 10 may be positioned between and held in place by the respiratory mask and the face of a user in order to absorb moisture, maintain proper positioning of the mask M, and greatly reduce or eliminate air from leaking between the mask M and the user's face.
  • the liner 10 is described herein primarily in relation to use with a CPAP mask, it is understood that the liner 10 may also be used with other types of respiratory masks such as, but not limited to, oxygen masks, respirators, and filtering masks.
  • the liner 10 includes a body 12 having an outer edge 14, an inner edge 16, and an opening 18 bounded by the inner edge 16.
  • the body 12 may be generally oval- shaped, elliptical, round, or triangular, or have any other shape appropriate for use with a respiratory mask, and is not limited to those shapes depicted herein.
  • the opening 18 is configured to at least partially receive the nose, mouth, or both nose and mouth, depending upon the type of mask, allowing air flow from an air source to be received by the user through the mask M.
  • the opening 18 may be generally elliptical or oval-shaped as shown, but is not intended to be limited to these shapes.
  • the outer edge 14 of liner 10 may have a shape scaled to a general shape of a face-engaging portion F of the respiratory mask M.
  • a perimeter of the liner outer edge 14, which may be continuous or discontinuous, is larger than a perimeter of the face-engaging portion F, wherein the liner 10 is configured to be releasably held between the mask M and a user's face such that the outer edge 14 extends beyond the mask face- engaging portion F around at least part of its perimeter.
  • the body 12 has a first portion 20 inward of the perimeter of the face-engaging portion F and a second, extending portion 22 outward of the perimeter of the face-engaging portion F.
  • the extending portion 22 extends outwardly from the face-engaging portion F, and may generally follow the contours of the user's face.
  • the outer edge 14 is spaced apart from the mask M.
  • the outer edge 14 may extend beyond the perimeter of the mask face-engaging portion F by between about 0.25 to 1.0 inches, or more particularly may extend between about 0.5 and 0.75 inches.
  • the area of the extending portion 22 may comprise at least about 5%, 10%, or 15% of the area of the body 12, but larger proportions of area represented by the extending portion 22 are also contemplated.
  • the extending portion 22 is configured to be in non-adhering communication with a user's face and serves to reduce air leaks from the perimeter of the mask M by acting as a baffle to regulate, limit, or diffuse air flow between the mask M and the skin, thus also stopping any resulting squealing-type noises created by such air leaks.
  • the body 12 is constructed from a single layer of absorbent material, wherein the thickness of the body 12 may be between about 0.005 to 0.05 inches, although these dimensions are not intended to be limiting.
  • the material may include cotton.
  • the material may include another material, such as silicone, with cotton embedded therein.
  • the material used for the construction of the body 12 may be stretchable to aid in adjusting and customizing the fit of the liner 10 to a particular user as described below.
  • the absorbent material may function to absorb moisture and/or oils from the user's skin and enable the mask M to maintain a consistent and comfortable position with respect to the user's face when in use.
  • an air source (not shown) delivers a constant flow of pressurized and humidified air to the CPAP mask M. Due to the moisture of the humidified air, facial perspiration (such as due to contact with the mask material), and oil from the skin, the mask M may slip on the user's face, thus leaking air and awakening the user during sleep.
  • the liner 10 may absorb such moisture and wick it away from the face and mask surfaces. As a result, proper positioning of the mask M with respect to the skin may be maintained, thus eliminating or greatly reducing air leaks and facilitating the ability for a user to wear their CPAP mask successfully throughout the night.
  • the single layer construction of the liner 10 may act as a sort of "second skin" upon the user's face.
  • the liner 10 is able to provide its baffle function without detracting from the prescribed fit of the mask M since the liner 10 does not appreciably alter the distance of the face- engaging portion F from the user's face.
  • Pressure markings from the mask M may also be reduced or eliminated by use of the liner 10.
  • the absorbent liner material may make use of facial creams possible while wearing the mask M, since direct contact of the skin with the mask material is avoided.
  • the liner 10 is held in place by the pressure of the respiratory mask M upon the face (e.g., by straps around the head).
  • the liner 10 could be at least partially fastened to the mask M, advantageously neither elastic nor another mechanism for securing the liner 10 to the mask M is required, allowing for ease of use and manufacture.
  • the position of the liner 10 can be adjusted if necessary while the mask M is secured, and the liner 10 is easily removable and replaceable when the mask M is removed.
  • Respiratory masks are offered in various shapes and sizes, including full-face, nasal, child-sized, and partial-face (hybrid) configurations.
  • Full-face masks typically include a wider bottom region for covering the mouth area and a narrower upper region for covering the nasal area.
  • Nasal masks generally cover the nasal area and not the mouth area.
  • Child-sized masks may have a proportionally smaller size.
  • Partial-face (hybrid) masks generally cover the mouth and may include a nasal interface.
  • the outer edge 14 of liner 10 may have a shape similar to a general shape of the face-engaging portion F for a selected mask M, wherein the shape of the outer edge 14 may represent a scaled version of the general shape of the face-engaging portion F.
  • the opening 18 may be sized to at least partially receive the user's nose and mouth (see FIG. 1).
  • the opening 18 may have a length of between about 1.0 to 3.0 inches and a width of between about 1.0 to 1.75 inches, and the body 12 may have a length of between about 4.5 to 7.5 inches and a width of between about 4.5 to 6.5 inches.

  • FIG. 24 illustrates placement of the liner 300 with the frame detached such that the hose aperture 350 is received over the hose connector of the mask, the export aperture 356 is aligned with an export air portion of the mask, the nasal aperture 354 is aligned with a nasal opening of the mask, and the mouth aperture 352 is aligned with a mouth opening of the mask. The user may then align his/her nostrils with the nasal aperture 354 and his/her mouth with the mouth aperture 352, and proceed to secure the mask.
  • FIG. 24 illustrates the frame attached to the mask with the liner 300 in place.
  • a user may adjust the positioning of the liner 300 if desired by pulling outward on the extending portion of the liner body 312 protruding beyond the perimeter of the respiratory mask, thereby providing a customized fit for a particular user.
  • at least one adhesive tab 360 may be provided at liner first end 318 for securing the liner 300 to the mask, such as near the hose connection, thus helping to ensure that export aperture 356 does not in any way obstruct the export air portion of the mask when the liner 300 is in use with the mask.
  • Tabs 360 do not change the configuration of the outer edge 314 of the liner 300 in the area of the nasal and mouth openings of the mask, where the outer edge 314 still loosely protrudes beyond the mask as described above.
  • Copper is a natural mineral having human nutritional benefit. Copper is also known to provide antimicrobial and potential wound healing properties.
  • the liners 10, 100, 200, 300 described herein may be manufactured with a copper or copper oxide material, such as CUPRON®.
  • CPAP therapy is the most widely used method for treating sleep apnea, but it is only successful when the equipment fits and works properly and allows the user to stay asleep and experience deep-sleep, rapid eye movement (REM) cycles, the sleep cycle in which the most beneficial rest takes place.
  • the liners 10, 100, 200, 300 may facilitate a more comfortable and effective CPAP therapy by contributing to a good fit of the CPAP mask M, providing comfort to the user, and reducing or eliminating air leaks, thus resulting in less disruption of sleep.
