The technology of this disclosure pertains generally to protective face mask, and more particularly to face masks having a seal around the user's face.
A problem with face masks is that they are not sealed against the user's face. In normal use, when the user exhales the exhaled gases vent around the edges of the mask. If someone sneezes or coughs, viruses can traverse the edges of the mask thereby exposing the user to the virus.
An aspect of the technology presented herein is to provide a dual mode face mask wherein in a first mode the mask can be used normally and in a second mode the mask can be sealed against the user's skin. In one embodiment, the mask has a peripheral adhesive band on its back (interior) side that faces the user. A separator is provided with a surface on one side that covers the peripheral adhesive band. The surface on the other side of the separator may be covered with a backing material comprising a cloth fabric or other material normally found on a mask. In a first mode, the mask is worn normally. In a second mode, the user can peel away the separator, thereby exposing the adhesive band. The user can then press this “sticky” mask onto his or her skin. This second mode of use is intended to seal the mask to the user's face when the user encounters a high danger situation such as exposure to a virus.
Further aspects of the technology described herein will be brought out in the following portions of the specification, wherein the detailed description is for the purpose of fully disclosing preferred embodiments of the technology without placing limitations thereon.
The technology described herein will be more fully understood by reference to the following drawings which are for illustrative purposes only:
Referring first to the embodiment of
An adhesive material 22 is placed around at least a portion of the periphery of the interior side of the mask (e.g., along the peripheral border or partially interior of the peripheral edge). Preferably the adhesive material is applied as a band that extends around the entire peripheral edge rather than in segments. The type of adhesive material is preferably the type used with medical electrode pads, such as EKG electrode pads or the like, which is a FDA approved adhesive for contacting human skin.
A separator 24 is provided to cover the band of adhesive material. The separator is preferably shaped to match the contour of the periphery of the mask and need only cover the band of adhesive. Accordingly, the separator does not obstruct the filter. The separator is preferably sized to cover the entire band of adhesive material so that the adhesive material is not exposed to the elements or contact the user's skin while in normal use of the mask.
The separator preferably comprises a material that adheres to the band of adhesive material with less strength than the adhesive material adheres to the filter. Non-limiting examples of material that can be used for the separator include waxy-type paper or the type of peel away pad that covers the adhesive on EKG electrodes. As a result, the separator can be peeled away from the band of adhesive material and removed from the mask without removing the adhesive material from the mask. The thickness of the separator material need only be sufficient to allow the separator material to be removed without substantial tearing or other condition that would make removal difficult. The separator may also exhibit some degree of rigidity or moldability if desired to allow the separator to be shaped. For example, a wire or the like could be embedded in the separator similar to bag ties or pipe cleaners.
One or more sections of backing material 26 are preferably, but optionally, attached to the periphery of the separator that would face the user. If included, the backing material preferably comprises the same type of material that would contact the user's face in a conventional mask. Other materials could be used as well. At least a portion of the one or more sections of said backing material is configured to rest against a least a portion of the user's face for comfort. It will be appreciated that since the backing material is attached to the periphery of the separator, the opening to the filter is not obstructed by the backing material. It will also be appreciated that the separator could be formed with an interior facing surface that provides comfort to the user without use of a backing material.
When the separator is removed, the band of adhesive material is exposed and at least a portion of the adhesive material can be pressed against the user's skin to seal at least a portion of, and preferably the entire, periphery of the interior side of the mask against the user's skin. In this way, the periphery of the mask can be sealed against the user's skin to prevent substance ingress around the periphery of the mask.
Therefore, this mask has two modes of use. The first mode of use is that the user can simply wear the mask like any other mask. But, when the user encounters a high danger situation, such as when near a coughing person, the user can back up to a safe distance and peel away the separator thereby exposing the band of adhesive material, and then press this “sticky” mask onto his or her skin. This second mode of use is intended to seal the mask to the user's face when the user encounters a high danger situation such as exposure to a virus. It will be harder for the user to breath with the mask sealed in this manner, especially for N95 or N99 masks or respirators, but the protection should be superior to that of a standard mask for sufficient time to change dressings, or change IV fluids with a sick patient, or even protect against exposure from a coughing or sneezing person who the user encounters on public transportation, in a grocery store or in some other public area.
It will be appreciated that the embodiment of a dual mode protective face mask 100 illustrated in
It will also be appreciated that this mask can be configured as a surgical mask, as a respirator mask, as a droplet blocking mask, as a virus blocking mask, or as any other type of protective mask where peripheral sealing would provide additional protection. The particular filter material can be chosen to reduce passage of various substances as desired.
In all of the embodiments, the protective face mask employs a conventional filter sufficient to reduce particular substances in the air from passing through the filter. For example, the filter may be a material that reduces passage of droplets, viruses, microbes, bacterial and other substances that could be toxic or otherwise create a danger to a user from exposure. All embodiments further comprise features that allow the face mask be used in a first, conventional mode, and a second, sealed mode.
