## Title
Facial skin indentation preventer

## Abstract

A facial skin indentation preventer has a central base core surrounded by an entrapment flap and a securing flap. The core and flaps have two layers: a soft moleskin or similar skin-contact layer and a second more rigid layer. A rigid cushion is attached to the central base core and a cannula or similar item can be placed thereon. The flaps are then folded inwards, over the rigid cushion, creating a cannula pocket above the rigid cushion and entrapping and holding the cannula therein. An entrapment hinge and securing hinge ensure the folds remain rounded and soft. A flap attachment is used to lock the securing flap in place and ensure the cannula stays within the cannula pocket.

## Background
TECHNICAL FIELD
The present invention relates generally to the fields of health and beauty, and more particularly to a facial skin indentation preventer.
BACKGROUND
Human skin, especially facial skin, can be sensitive. Items that rub, press into, or otherwise contact skin for extended periods can lead to redness, indentation, irritation, swelling, and even sores. This is especially true for items such as mask straps, cannulas, and similar objects (collectively, “cannulas”) that put constant pressure on the facial skin over longer periods of time. For example, many people utilize nasal cannulas for delivery of supplemental oxygen. The hollow plastic tubing that feeds the oxygen usually runs from behind the ears to the nose. If worn during sleep, such tubing is often pressed into the wearer's facial skin causing red, irritated indentations or “lines” across the wearer's cheeks. Such lines can persist for hours after removal of the causative agent (i.e., the cannula, mask strap, etc.) and can be unsightly as well as unhealthy.
Therefore, what is needed is a device that can be used in combination with cannulas that works to prevent facial skin indentations, irritations, etc.

DETAILED DESCRIPTION
In the following discussion, numerous specific details are set forth to provide a thorough understanding of the present disclosure. However, those skilled in the art will appreciate that embodiments may be practiced without such specific details. Furthermore, lists and/or examples are often provided and should be interpreted as exemplary only and in no way limiting embodiments to only those examples.
Exemplary embodiments are described below in the accompanying Figure. The following detailed description provides a comprehensive review of the drawing in order to provide a thorough understanding of, and an enabling description for, these embodiments. One having ordinary skill in the art will understand that in some cases well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.
Referring now to the drawings, FIG. 1 illustrates a perspective view of an exemplary embodiment of a facial skin indentation preventer 10 in a pre-installation configuration. The preventer 10 is shown in an open configuration with a cannula tube 90 attached to nasal prongs 95 (both shown in broken lines) placed on top of the preventer 10. The embodiment of the preventer 10 illustrated in FIG. 1 comprises a central base core 60, an entrapment flap 20, a securing flap 50, an entrapment hinge 30, a securing hinge 40, and a flap attachment 70. It is important to understand that the preventer 10 can be utilized with any strap, tube, or similar object (again, collectively “cannulas”) that would otherwise press into the skin of a user.
The central base core 60, the entrapment flap 20, and the securing flap 50 are illustrated in FIG. 1 as each comprising a plurality of layers. The plurality of layers includes an outer skin-contact layer 24, 64 and 54 and an inner rigidity layer 22, 62 and 52. The outer skin-contact layer 24, 64 and 54 can comprise a soft, resilient material such as mole-skin or other similarly soft fabric or material. The inner rigidity layer 22, 62 and 52 should be a somewhat stiff/rigid material that is still flexible, but has enough stiffness so that the preventer 10 does not completely mold to the curvature of the face when the cannula 90 that is running through the preventer 10 is pulled tight against the face, or that the edges of the preventer 10 will at least spring back up off the face when the strain on a cannula 90 is relaxed. A stiff non-stick and/or waxed paper can be used for the inner rigidity layer 22, 62 and 52, while other materials are contemplated in other embodiments.
The central base core 60 can be generally rectangular in shape, 1.5 inches wide by 3.5 inches long. In other embodiments, other widths and lengths are contemplated. Attached to the central base core 60 on one long side is an entrapment flap 20. Attached on the other long side is a securing flap 50.
In order to install the preventer 10 on the cannula tubing 90, the user simply places the cannula tubing 90 lengthwise along the center of the central base core 60 and the traps the tubing 90 in place by folding the entrapment flap 20 over the tube, thereby sandwiching the cannula 90 between the entrapment flap 20 and the central base core 60. In order to ensure the cannula stays in place, the user then folds the securing flap 50 over top of the entrapment flap 20 and locks it in place. In the embodiment illustrated in FIG. 1, a flap attachment 70 is used to lock the securing flap 50 in place. This is accomplished by removing the adhesive cover 73 from the securing flap adhesive 75 in order to expose the adhesive before folding the securing flap 50 over. Then, the user simply presses the adhesive onto the entrapment flap 20 and locks the two together. The cannula is thereby trapped between the entrapment flap 20 and the central base core 60 and secured therein by attachment of the securing flap 50 to the entrapment flap 70. In other embodiments, other means of entrapping the cannula on top of the central base core 60 are contemplated. For example, one or more small spring clamps could grasp the cannula tubing, or a sandwich of hook and loop material with the tubing therebetween could be used, etc. However, embodiment illustrated in FIG. 1 provides a number of advantages over these other embodiments: it is simple to manufacture; provides smooth, rounded side edges; provides a soft skin-contact surface whether the preventer 10 is upside-down or right-side-up; etc.
Between the entrapment flap 20 and the central base core 60 is an area called an entrapment hinge 30 that provides extra materials that can act as a hinge when the entrapment flap 20 is folded back over the central base core 60 during installation (see FIG. 4). Similarly, between the securing flap 50 and the central base core 60 is an area called a securing hinge 40 that provides extra materials that can act as a hinge when the securing flap 50 is folded back over the central base core 60 during installation (see FIG. 4). When the two flaps 20 and 50 are folded over during installation, the two hinges 30 and 40 form soft, rounded edges that run the length of the long sides of the central base core 60. These soft, rounded edges are much preferable to sharp, distinct edges that would otherwise be found if the flaps weren't folded over but were instead separate pieces stacked on top of the central base core 60 (or in the case of only one of the two flaps being used).
The central base core 60 has attached thereto a rigid cushion 80 comprising a double-sided foam tape or any other suitably stiff and cushiony material. A one-thirty-second inch or one-sixteenth inch thickness can be used. Other thicknesses can be used in other embodiments. Double-sided foam tape allows the material to be easily attached to the inner rigidity layer 62 of the central base core (by simply peeling off the adhesive protection from the bottom of the foam tape and sticking it to the top of the central base core 62). The top surface of the second tape can be left with the adhesive cover in place to ensure that the cannula can be slid back and forth over the rigid cushion 80 in order to reposition the preventer 10 along the length of the cannula 90 as desired. Alternatively, the second tape can have the adhesive cover removed and the preventer 10 can then be attached to the cannula 90 at a specific location. In yet other embodiments, other somewhat rigid cushiony material(s) can be used instead of double-sided foam tape. The rigid cushion 80 may have adhesives on zero, one, two or more faces and may attach to the inner rigidity layer 62 in other ways.
In yet another embodiment, the flap attachment 70 can be pre-installed on the outer skin-contact layer 24 of the entrapment flap 20. In this configuration, once the entrapment flap 20 is closed over the cannula 90, then the adhesive cover 73 can be removed from the flap attachment 70 in order to expose the flap adhesive 75 and then the securing flap 50 can be folded over onto the adhesive, thereby locking the two flaps together.
FIG. 2 illustrates a top plan view of an exemplary embodiment of a facial skin indentation preventer 10 in a pre-installation configuration. When viewed from above, only the top surfaces of the pre-installation preventer 10 are visible: the inner rigidity layer 22 of the entrapment flap 20, the rigid cushion 80 on top of the central base core 60, and the adhesive cover 73 of the flap attachment 70 on top of the securing flap 50. Also, the entrapment hinge 30 and securing hinge 40 areas are visible.
FIG. 3 illustrates a side elevation view of an exemplary embodiment of a facial skin indentation preventer 10 in a pre-installation configuration. In the side view, the two layers that make up the entrapment flap 20, central base core 60, securing flap 50, and hinges 30 and 40 are visible: the outer skin-contact layer 24, 64 and 54 and the inner rigidity layer 22, 62 and 52. Similarly, the two layers that make up the flap attachment 70 are visible as well: the adhesive cover 73 and the securing flap adhesive 75. During installation, the adhesive cover 73 is removed, exposing the securing flap adhesive 75 for attachment to the outer skin-contact layer 24 of the entrapment flap 20.
Note the round cannula tube 90 is illustrated in FIG. 3 using broken lines. The cannula tube is placed atop and along approximately the center of the rigid cushion 80. The entrapment flap 20 can then be folded along the entrapment hinge 30 to trap the cannula between the entrapment flap 20 and the rigid cushion 80. The securing flap 50 can then be folded along the securing hinge 40 to secure the cannula in place. The flap attachment 70 ensures that the installed preventer 10 is able to keep the cannula in place during repositioning of the user, changing the location of the preventer 10 along the cannula tubing, etc.
FIG. 4 illustrates a side elevation view of an exemplary embodiment of a facial skin indentation preventer 10 in an installed position around a cannula tube 90. In its installed configuration, the preventer 10 creates a cannula pocket 94 which is a space within which a cannula 90 can rest. It is important to understand that the preventer 10 can be utilized with any strap, tube, or similar object (again, collectively “cannulas”) that would otherwise press into the skin of a user. Thus, the cannula pocket 94 is designed to hold within it any strap, tube or similar object, not just a cannula. The cannula pocket 94 is created when the inner rigidity layer 22 of the entrapment flap 20 is brought near the top surface of the rigid cushion 80. This occurs when the entrapment flap 20 is folded along the entrapment hinge 30 and placed over the central base core 60.
In this illustration, the rounded long edges of the preventer 10 are apparent as the hinges 30 and 40 are illustrated in their hinged configuration rather than flat as in FIGS. 2 and 3. The cannula tubing 90 is clearly illustrated as being entrapped in the cannula pocket 94, i.e., the space between the inner rigidity layer 22 of the entrapment flap 20 and the top surface of the rigid cushion 80 of the central base core 60.
The overlapping of the dual-layer entrapment and securing flaps above the tubing 90 ensures proper cushioning should the preventer 10 get flipped over and present the outer skin-contact layer 54 of the securing flap 50 to the user's facial skin instead of the outer skin-contact layer 64 of the central base core 60, as is the norm. In either case, the user can roll-over onto the cannula tubing 90 when sleeping, and yet the preventer 10 will distribute the pressure from the tubing 90 across a wider surface area and ensure that the user doesn't awake with a red, irritated indentation from the cannula tubing pressing into their cheek or other skin.
It should be apparent from the above discussion that any other strap, tube, cord, or material can be wrapped with the preventer 10 and it will ensure the prevention of skin indentation therefrom. Similarly, the preventer 10 can be used on straps, tubes, cords, or other materials that contact other portions of a person's skin in addition to those touching the facial skin and will similarly prevent those materials from causing uncomfortable and unsightly indentations.
