The present embodiments are directed to a transparent anti-contagion facemask.
The World Health Organization and most medical professionals agree that facemasks are an effective way to reduce transmission of airborne pathogens that cause respiratory illness. There are a variety of different facemasks from N-95 facemasks, constructed with facemask material that filters out 95% of 0.3 μm particles, to simple cloth and surgical facemasks that somewhat block moisture particles from a person's exhalant. Though protective, present day facemasks tend to muffle the sound of a person's speech making them hard to understand.
It is to innovations related to this subject matter that the claimed invention is generally directed.
The present embodiments are directed to facemasks with some embodiments directed to transparent anti-contagion facemasks that do not obstruct visibility of a person's mouth when worn. One problem with a typical, widely used, facemask is the difficulty in understanding a person speaking when they are wearing the typical facemask. Not only does the listener have to contend with the muffled speech of a person talking through a facemask, communication is made worse by covering up, or otherwise hiding, the wearer's mouth and face with opaque filter material. Certain embodiments of the present invention aim to address this problem and others by way of a clear/see-through filtration mask embodiment that does not visibly obstruct a person's mouth. Coupling an adequate filtration material with the transparent facemask, one object of the present invention seeks to improve protection against airborne viruses compared to a simple cloth facemask. Though embodiments of the transparent facemask may not eliminate the muffled speech of a person talking while wearing the transparent facemask, communication is certainly improved by virtue of seeing the wearer's face while they are speaking.
With this in mind, certain embodiments of the present invention therefore contemplate a passive transparent facemask comprising: a face covering cup configured to cover a mouth and nostrils of a wearer with a mask midpoint defined as a point on the face covering cup that is equidistant between the mouth and the nostrils when the facemask is worn, the face covering cup is defined by a cup periphery that is further defined by a nose periphery region adapted to traverse the bridge of a nose of the wearer, a pair of cheek periphery regions adapted to traverse along cheeks of the wearer and a chin periphery region adapted to traverse along or above a jawline of the wearer, the face covering cup further defining a midline that bisects the face covering cup midway between the nose periphery region and the chin periphery region; a plurality of breathing perforations dispersed in the face covering cup at a distance greater than 1.25 inches from the midpoint; and at least one filter that covers the breathing perforations. Exchange of air can essentially only occur through the breathing perforations via the at least one filter.
Yet another embodiment of the present invention envisions a passive transparent respirator assembly comprising: a transparent face covering cup comprising a nose covering region configured to cover human nostrils and at least a portion of a human nose, a mouth covering region configured to completely cover a human mouth without any external viewable obstruction to the human mouth when the human mouth is closed, a chin covering region configured to cover at least a portion of a human chin, and two cheek covering regions located on either side of a midline and configured to cover a portion of a human cheek, the midline is defined as bisecting the face covering cup extending along and bisecting the nose covering region and the chin covering region, the face covering cup is unitary, the face covering cup is further defined by a cup exterior surface and a cup interior surface; at least one aperture extending through the face covering cup from the cup exterior surface to the cup interior surface, the at least one aperture covered by at least one filter, which together comprise a passive respirator intake pathway, there is no other pathway other than the passive respirator intake pathway between the cup exterior surface and the interior surface.
Initially, this disclosure is by way of example only, not by limitation. Thus, although the instrumentalities described herein are for the convenience of explanation, shown and described with respect to exemplary embodiments, it will be appreciated that the principles herein may be applied equally in other types of situations involving similar uses of transparent facemasks. The phrases “in one embodiment,” “according to one embodiment,” and the like generally mean the particular feature, structure, or characteristic following the phrase is included in at least one embodiment of the present invention, and may be included in more than one embodiment of the present invention. Importantly, such phases do not necessarily refer to the same embodiment. If the specification states a component or feature “may”, “can”, “could”, or “might” be included or have a characteristic, that particular component or feature is not required to be included or have the characteristic. In what follows, similar or identical structures may be identified using identical callouts.
Certain embodiments of the present invention are directed to transparent anti-contagion facemasks that do not obstruct visibility of a person's mouth when worn. One problem with a typical, widely used facemask is the difficulty in understanding a person speaking when they are wearing the typical facemask. Not only does the listener have to contend with the muffled speech of a person talking through a facemask, communication is made worse by covering up, or otherwise hiding the wearer's mouth and face with opaque filter material. Accordingly, some embodiments described herein present a clear/see-through filtration mask embodiment that does not visibly obstruct a person's mouth with a filtration system along the periphery or optionally near a person's chin or cheeks. Though embodiments of the transparent facemask may not eliminate the muffled speech of a person talking while wearing the transparent facemask, communication is improved by virtue of seeing the wearer's face while they are speaking.
Several different clear/transparent facemask embodiments are presented herein including a transparent anti-contagion facemask with and without a breather filter gasket along the periphery. The anti-contagion facemasks herein provide a common feature of being able to make visible a person's mouth through a facemask without obstruction, which facilitates seeing a person's mouth and lips while they are speaking. Some embodiments feature at least one filtered breather port in the facemask with an added air filtration gasket attached to the periphery of the facemask. The air filtration gasket can compress against the face when worn. These embodiments aim to improve the effectiveness of facemasks by providing a semipermeable filtration gasket along the periphery of the facemask to correct for the present day problems of insufficiently sealed facemasks against the person's face. A facemask that is insufficiently sealed will have gaps at the interface between the mask and a person's face through which unfiltered air will freely enter the space within the mask because air will flow along the path of least resistance. One object of the present invention is to improve facemask effectiveness by placing a filter gasket along the facemask periphery, which compresses against a person's face when worn properly. With the filter gasket compressed against the person's face, any air either entering the mask or escaping from the mask along the mask's periphery will be filtered through the filter gasket forming the facemask periphery. Optional embodiments contemplate that instead of a filter gasket, the facemask seal against a person's face is made by providing a low durometer flange that conforms to the person's face. Yet other embodiments contemplate the facemask featuring a conforming flange made from the same material as the rest of the facemask that presses against a person's face thereby essentially forming a seal against a person's face to force a pathway of air only through the filters in the facemask.
The face covering cup 101 defines a cup periphery 102 that is shaped to traverse the bridge of a person's nose 512 and along their cheeks 514 and jaw line 506, as shown. In other words, the cup periphery 102 essentially rests along the bridge of a person's nose 512, their cheeks 514, their jawline 506 and their chin 508. In the present embodiment, a gasket filter armature 130 is configured and arranged to cover the cup periphery 102. The gasket filter armature 130 provides structure to improve a contact seal of the filter-to-face contact periphery 106. Certain embodiments envision the gasket filter armature 130 being a pliable tubular structure, such as foam or latex, for example. The filter material can be either the same or different from the filter gasket 105. In the present embodiment, the gasket filter armature 130 comprises an armature channel 132 that receives the cup periphery 102. The gasket filter armature 130 can be glued, pressure fit, bonded in some other way or unitarily formed in place along the cup periphery 102, to name just a few examples of connecting the gasket filter armature 130 along the cup periphery 102. A filter gasket 105 covers the gasket filter armature 130 and a ‘small portion’ of the face covering cup 101 along the cup periphery 102 via a gasket filter channel 108. By ‘small portion’ it is meant that at least just enough of the face covering cup 101 is used/required to accomplish holding/supporting the gasket filter armature 130 in place via the armature channel 132. In the present embodiment, the filter gasket 105 covers the filter gasket armature 130. There are a number of ways the filter gasket 105 can be attached to the cup periphery 102, which can include adhesive or a mechanical latch configuration, as will be appreciated by a skilled artisan once intellectually in possession of the present invention.
The filter gasket 105 is made out of a porous material that in some embodiments is the same material as the breather port filter 110. The filter gasket 105 compresses against a person's cheeks 514, jawline 506 and across the bridge 512 of their nose 510 along the filter-to-face contact periphery 106 when the facemask 100 is strapped or otherwise retained over a person's nose 510 and mouth 504. Certain embodiments envision the filter gasket 105 thick enough, i.e., constructed in a suitable manner, to close any gaps between the person's face 515 and the filter-to-face contact periphery 106. Embodiments that include the filter gasket 105 and gasket filter armature 130 combination improve the seal around the filter-to-face contact periphery 106. The term “seal” as used in conjunction with embodiments of the present invention is envisioned to mean essentially full/intimate contact of the filter-to-face contact periphery 106 with a person's face 510 even though filtered air can pass in and out of the facemask interspace 175 through the filter gasket 105. Certain embodiments envision the filter gasket 105 made from an N-95 or N-99 filter material, or some other filter material that is efficient in filtering viruses and/or bacteria (germs) from passing there through. With the filter gasket 105 pressed tightly against a human face 515 along the filter-to-face contact periphery 106, there will be essentially no gaps between the facemask periphery 102/106 and the wearer's face 515. The present system possesses two basic paths of filtered air that can flow into and out from the facemask interior 175. The two basic paths are: 1) air flowing through the filter gasket 105, and 2) air flowing through one or more filters covering the at least one breather port 135 in the face covering cup 101.
The term “passive”, as used in the element passive transparent respirator assembly 150, is defined as the action of air passing from outside of the passive transparent respirator assembly 150 to the inside of the passive transparent respirator assembly 150 only under the power of a person breathing on their own and without the assistance of an external pumping device. Hence, the passive transparent respirator assembly 150 operates only via a human breathing in and out and without the assistance of an external pump.
The transparent facemask cup 101 comprises a cup periphery 102 (and 102A, which is the cup periphery as seen through the outer surface 140 of the transparent facemask cup 101) that when worn by a person 500 traverses the bridge 512 of the person's nose 510, along their cheeks 514, and around their jaw line 506. In the present embodiment, the cup periphery 102 comprises a lip 103, which in certain embodiments is a bead that extends outwardly from the cup exterior surface 140 as shown by the arrow 103a. Some embodiments contemplate the lip 103 extending outwardly from the cup exterior surface 140 along only a part of the cup periphery 102 while other embodiments envision the lip 103 extending along the entire cup periphery 102. As described earlier, the molded nose portion 120 in the front of the face covering cup 101 generally conforms to the anatomy of a person's nose 510 terminating at the bulbous end of a person's nose 510. Just below the molded nose portion 120 is an indent 127 in the face covering cup 101 that is directly, or otherwise immediately, in front of where a person's nostrils 502 would be when the facemask 100 is worn. As appreciated by the proportions of the transparent respirator assembly 150, the front breathing filter 110 is positioned directly in front of a person's chin 508 below where a person's mouth 504 would approximately reside (shown by the “X” 155) under the transparent respirator assembly 150 when worn. Based on the placement of the front breathing filter 110 and the clear/see-through transparent facemask cup 101, the wearer's mouth 504 is unobstructed from the view of an outsider when the facemask assembly 150 is worn. It should be appreciated that in the present embodiment the head strap attachment anchors 115 are placed on either side of the front breathing filter 110. However, there are a number of other suitable locations on the face covering cup 101 where the head strap anchors 115 can be disposed without departing from the scope and spirit of the present invention. Certain embodiments of the present invention contemplate the passive transparent respirator assembly 150 used with or without a filter gasket 105 (the gasket being integrated or otherwise) that may essentially seal the passive transparent respirator assembly 150 against the person's face 500.
Certain embodiments envision the mouth covering region 117 configured to completely cover a human mouth 504 without any external viewable obstruction to the human mouth 504 when the human mouth 504 is closed (that is with lips pressed together as shown in
A chin covering region 119 below the mouth covering region 117 (in the below direction 184) is configured and located to essentially cover at least a portion of the wearer's chin 508. The cheek covering regions 113 are shown covering a portion of a person's cheeks 514. As is further shown, the midline 422 extends along the front of the face covering cup 101 bisecting the nose covering region 120 the mouth covering region 117 and the chin covering region 422. The cup center point 424 is located along the midline 422 approximately between wearer's nostrils 502 and a wearer's mouth 504. The breather port filter 110 and breather port apertures 135 are in the chin covering region 119 directly in front of the person's chin 508. Hence, the wearer's mouth 504 is unobstructed by the breather port filter 110, which, in certain embodiments, can further extend into the cheek region 113, such as along the jawline 506.
The gasket facemask embodiment 400 is essentially a periphery air filtered facemask that generally comprises a clear (transparent) face covering cup 401 that is sized and configured to cover both a human mouth 504 and nostrils 502. The face covering cup 401 is defined by a cup that extends to a cup periphery 402. The cup periphery 402 is intended to traverse the bridge 512 of a person's nose 510 along their cheeks 514 and at or above their jawline 506, similar to the other facemask embodiments 100, 200, 300 and 700. The face covering cup 401 is further defined by a reference midline 422 that bisects the face covering cup 401 along the nose 510 from the bridge 512, between the nostrils 502 and across the mouth 500. The face covering cup 401 further comprises a plurality of breathing perforations 408, which are not limited to the triangular-shaped perforations depicted in the present embodiment. As shown in the present embodiment, the breathing perforations 408 are dispersed along the cup periphery 402 within a cup periphery region 428. In some embodiments, the breathing perforations 408 are dispersed less than 0.75 inches from the cup periphery 402. In other words, the cup periphery region 428 is less than 0.75 inches wide as defined from the cup periphery 402. In other embodiments, the breathing perforations 408 are essentially the only perforations that pass through the face covering cup 401. The breathing perforations 408 extend along the cup periphery 402 (in a U-shape from about 2:00-10:00 as seen on a clock face) except for a bridge periphery region 430, as shown. Other embodiments imagine the perforations extending over the bridge portion 430, however this might be blocked off by a person's nose bridge 512. In this arrangement the breathing perforations 408 are no less than 1.5 inches from the midpoint 424, but in other arrangements are no less than 1.00 inches from the midpoint 424.
A filter band 405 is configured to cover the breathing perforations 408 whereby air 418 (shown by the squiggly line) can be exchanged through the breathing perforations 408 in the filter cover band 414 only by way of the breather filter band 405. In this way, only filtered air can pass through the breathing perforations 408 from the outside 553. The breathing filter band 405 is envisioned to be any filter material comprising a pore size that meets a desired specification. For example, a pore size of less than 0.3 μm will filter out 0.3 μm particles, such as viruses. A pore size distribution where 95% of the pores are less than 0.3 μm is an N-95 filter material. Certain embodiments envision a filter band 405 that is reusable. In this embodiment, the reusable filter band 405 is able to be revitalized or otherwise essentially renewed to function at or near capacity. Examples of revitalization can be accomplished by way of washing, exposure to chemicals, ultraviolet light, heat, suction, or some other means of revitalizing or cleaning the filter band 405 that would be known to those skilled in the art. The filter band 405 can be attached to the face covering cup 401 by way of an adhesive or some mechanical latching mechanism, such as a filter cover 420. A skilled artisan will appreciate that the filter can be for viruses, bacteria, or other contamination in healthcare and/or outside healthcare, such as woodworking, for example.
The present embodiment illustratively depicts a filter cover 420 configured and arranged to mechanically retain or otherwise fix the filter band 405 to the face covering cup 401. By mechanically attaching to the face covering cup 401, certain embodiments contemplate that the filter cover 420 snaps into receiving features (not shown) in the face covering cup 401 or optionally slides around or otherwise fixes onto (snaps over) the cup periphery 402, just to name several of many species variations. The filter cover 420 generally comprises a plurality of filter cover perforations 410 that provide a pathway to the breathing perforations 408 via the filter band 405. The filter cover perforations 410, located between a face contact rim 406 and the mask periphery 404 in the filter cover band 414, are configured to align with the breathing perforations 408 in the face covering cup 401 so that the inside facemask environment is in communication with the outside environment via the filter 405. The face contact rim 406 is configured to contact a human face 515 over the bridge 512 of a person's nose 510, along their cheeks 514, and at or above their jawline 506. Certain embodiments envision the face contact rim 406 essentially sealing against a person's face 515 to restrict or otherwise inhibit the passage of air 418 to pass essentially only through the breathing perforations 408. In this way, filtered air moves into the facemask 400 via (essentially only through) the breathing perforations 408. Some embodiments envision the facemask rim 406 being silicone, a textile material, filter material, a flexible flange, or some other material and configuration that conforms to a person's face 515. In the event the facemask rim 406 is filter material, filtered air is envisioned to move through the facemask rim 406 into the facemask 400. The filter cover 420 can further possess a filter cover gap 436 between an interior filter cover surface 434 and the filter band 405. In some embodiments, the filter cover gap 436 is imagined to be less than 0.25 inches deep between the interior filter cover surface 434 and the filter band 405. Other embodiments envision a filter cover nose bridge portion 412 being bendable over the bridge 512 of a person's nose 510, such as by way of a compliant metal material to improve the fit and seal.
Regarding the exploded view line drawing of the passive transparent facemask 700 of
In the present embodiment, the breather filter 705 can simply be a sheet of flexible filter material or optionally a semi-rigid U-shaped filter element that closely conforms to the filter port region 728. As shown in this embodiment, the breather filter 705 is a U-shaped filter element that is made semi-rigid by a supporting structure 746 with structures that mate or otherwise conform to the filter port region 728. The semi-rigid supporting structure 746 can be plastic, or filter material impregnated with a stiffening binder, such as glue for example. The breather filter 705 is held in place over the filter port region 728 via the filter and contact rim 720.
The filter cover and contact rim 720 comprises a filter cover 717, cuff recess slot 709 and a contact rim 734. In the present embodiment, the contact rim 734 can be a pliable polymer that flexes to conform to the shape of a person's face 515 to essentially create a seal so that the only air passing into and out from the facemask 700 is by way of the filter slots 736 and 708. The filter cover and contact rim 720 can be a unitary element constructed from a single piece of material. Optional construction of the filter cover and contact rim 720 envisions a composite construction. The filter cover and contact rim 720 can comprise a low durometer flexible flange 725 that conforms to a person's chin 508 and cheeks 514 with a higher durometer flexible nose bridge region 712 and filter cover 717. Yet other embodiments envision the filter cover 717 being a much stiffer plastic material. The filter cover 717 essentially conforms to and covers the curved (chin covering) wall/curved panel 732 of the face covering cup 701. The filter cover 717 comprises a plurality of filter cover ribs 714 that overlay or otherwise align with the face covering cup ribs 714A so that the outside environment 553 is in communication with the inside environment 175 (shown in
