FACE MASK HAVING TRANSPARENT PLASTIC PIECE

BACKGROUND

[1] A face mask is commonly worn by health professionals during events such as surgeries and other medical procedures, dental procedures, and the like to protect both the wearer and the surrounding parties from contamination. The masks are designed to catch liquid droplets and aerosolized particles from the wearer's mouth and nose, and to stop bodily fluids and other splashes from reaching the covered portions of the wearer's face. Face masks are typically made from paper or other non-woven material, and often have three layers (i.e., 3-ply). Typically, these layers consist of a melt-blown material that is placed between non-woven fabrics. The melt-blown material acts as a filter that prevents contaminants from entering or exiting the mask. Most face masks include pleats or folds that enable the expansion of the mask's surface area, so that it covers the area of the wearer's face from the nose to the chin. Face masks used for surgical procedures typically have four straps that are tied behind the head. Other variations include those that are affixed to the wearer's face via ear loops, where a string-like material is attached to the mask and placed behind the ears, and masks that have an elastic headband strap that is placed behind the head.

DETAILED DESCRIPTION

[29] Miscommunication is a leading cause of medical errors. The potential for

miscommunication may be especially compounded in deaf and hard of hearing medical patients when standard face masks, such as a surgical mask, are used. It is estimated that approximately 55% of communication is nonverbal. Standard surgical masks block the wearer's face and prevent the ability of others to see facial expressions and read lips of the mask wearer.

Implementations of the disclosed subject matter may provide a mask with full-face visibility. The mask may provide protection, and may provide comfort and breathability to the wearer. The face mask of the disclosed subject matter may allow patients and other individuals to see more of the wearer's face and facial expressions, while the mask may provide safety, comfort, and breathability to the wearer.

[30] Although many people may benefit from whole face communication, it may be especially important for: deaf and hard of hearing patients, medical staff, medical students, laboratory technicians, and scientists; limited English Proficiency patients; sign language interpreters and agencies; dentists, dental hygienists, and other dental health professionals;

patients prone to or experiencing stress and anxiety; pediatric patients; immunosuppressed patients; cancer patients; HIV/AIDS patients; organ transplant recipients; medical staff who cannot receive seasonal flu vaccinations and must wear masks; and all medical staff so that they can see their colleagues' faces and better understand dialogue in dental and/or medical

environments, such as an operating room, and/or in noisy environments. People in non-medical settings that use face masks may also benefit from whole face communication.

[31] Implementations of the disclosed subject matter may include a mask having a transparent viewing area. In some implementations, the viewing area may be translucent, opaque, or the like. The transparent viewing area may be coated with an anti-fog or fog-resistant coating to provide full-face visibility. The mask may include features that provide for comfort and breathability.

[32] Implementations of the disclosed subject matter may provide a face mask having a transparent plastic piece and/or extended plastic piece, and conformable members affixed to a back side of the plastic piece. The plastic piece may provide improved visibility to whole face of the user of the face mask, such that others may observe the full facial expressions and/or lip movements of the user. The plastic piece may act as an impermeable barrier for air and/or other particulates and may provide increased protection compared to conventional face masks made from cloth-like materials. The conformable members of the face mask may provide better fit, less slipping, increased stability, and/or increased breathability for a user of the face mask, compared to conventional face masks. The conformable member may push the transparent plastic piece away from the user's face and/or lips to prevent them from touching the transparent plastic piece and/or to increase comfort and breathability by allowing for air to flow in and/or out from the sides of the face mask, and/or the back of the face mask. That is, the conformable members may seal the top and bottom of the mask and/or create a "pocket" for air flow along with the plastic piece by preventing air flow from going forward and/or out of the top and/or bottom of the face mask.

[33] FIGS. 1 A-1M show views of a face mask 100 according to implementations of the disclosed subject matter. In particular, FIG. IB shows a view of back side of the face mask 100 of FIG. 1 A, including conformable members affixed to portions of the back side. FIG. 1C shows a side view of the face mask 100, and FIG. ID shows a top view of the face mask 100. FIG. IE shows another view of back side of the face mask 100 of FIG. IB, including a first conformable member and a second conformable member affixed to portions of the back side. FIG. IF shows a view of the front side of the face mask 100. FIGS. 1G-1K show difference views and

implementations of the face mask 100 that includes an extension of a plastic piece above a conformable member. FIG. 1L shows the face mask 100 having a single conformable member, and FIG. 1 M shows an implementation of the face mask 100 having straps that form first and second loops.

[34] The face mask 100 of FIGS. 1A-1M may include a transparent plastic piece 102 having a front side 104, a back side 106, a top side 108, a bottom side 1 10, a left side 1 12, and a right side 1 14. The transparent plastic piece 102 of FIGS. 1 A-1M is shown in greater detail and discussed below in connection with FIG. 4. The transparent plastic piece 102 may, in some implementations, include extension 102a as shown in FIGS. 1G-1K as described below. The extension 102a may cover the eyes and/or upper head region of a user. In some

implementations, the viewing area of the transparent plastic piece 102 and/or extension 102a may be translucent, opaque, or the like. The transparent viewing area of the transparent plastic piece 102 and/or extension 102a may be coated with an anti-fog or fog-resistant coating to provide full-face visibility, where the coating may prevent the condensation of water in the form of small droplets on a surface of the mask which resemble fog. That is, the anti-fog or fog-resistant coating may minimize moisture collection (e.g., from the breath of a wearer of the face mask 100) on the back side 106 of the transparent plastic piece 102 and/or extension 102a.

[35] A first conformable member 1 16 may be affixed to a first portion 1 18 of the back side 106 of the transparent plastic piece 102 and disposed parallel to the top side 108 of the transparent plastic piece 102. The first conformable member may be formed, molded, and/or constructed from foam or any other suitable material. The first conformable member 1 16 may be shown in greater detail in FIGS. 2A-2C and described below.

[36] A second conformable member 120 may be affixed to a second portion 122 of the back side 106 of the transparent plastic piece 102 and disposed parallel to the bottom side 110 of the transparent plastic piece 102. The second conformable member 120 may be formed from foam or any other suitable material that may conform to a portion of the face of the wearer of the face mask 100.

[37] At least one first strap 124 may have a first end 126 and a second end 128. As used throughout, the at least one first strap 124 may be a single strap, or may include two or more

straps. When the at least one first strap 124 is a single strap, a portion of the at least one first strap 124 may be affixed parallel to the top side 108 of the transparent plastic piece 102 between the first end 126 and the second end 128 on either the front side 104 or the back side 106 of the plastic piece 102. In implementations where the at least one first strap 124 is two or more straps, a portion of one of the straps may be affixed to the plastic piece 102 opposite the first end 126, and a portion of another one of the straps may be affixed to the plastic piece 102 opposite the second end 128. The two or more straps of the at least one first strap 124 may be affixed to the front side 104 or the back side 106 of the plastic piece 102. The portion of the at least one first strap 124 may be affixed parallel to the top side 108 using an adhesive, by bonding, by using ultrasonic welding, stitching, or any other suitable method of affixing the at least one first strap 124 to the plastic piece 102. At least one second strap 130 may have a first end 132 and a second end 134. As used throughout, the at least one second strap 130 may be a single strap, or may include two or more straps. When the at least one second strap 130 is a single strap, a portion of the second strap 130 is affixed to the bottom side 1 10 of the plastic piece between the first end 132 and the second end 134 on either the front side 104 or the back side 106 of the plastic piece 102. In implementations where the at least one second strap 130 is two or more straps, a portion of one of the straps may be affixed to the plastic piece 102 opposite the first end 132, and a portion of another one of the straps may be affixed to the plastic piece 102 opposite the second end 134. The two or more straps of the at least one second strap 130 may be affixed to the front side 104 or the back side 106 of the plastic piece 102. The portion of the at least one second strap 130 may be affixed to the bottom side 108 using an adhesive, by bonding, by using ultrasonic welding, stitching, or any other suitable method of affixing the at least one second strap 130 to the plastic piece 102. The portions of the at least one first strap 124 and the at least one second strap 130 may be affixed to the transparent plastic piece 102 so that a portion, such as 50%-95%, of the front side 104 and/or the back side 106 of the transparent plastic piece 102 is uncovered. The first strap 124 and the second strap 130 may be formed of a fabric, such as a woven fabric or a knitted fabric, and/or any other suitable material. In some implementations, the fabric may include elastic material, or may be elastic.

[38] In some implementations where the at least one strap 124 and/or the at least one strap 130 are affixed to the back side 106 of the plastic piece 102, the at least one first strap 124 may be disposed between the transparent plastic piece 102 and the first conformable member 1 16, and the at least one second strap 130 may be disposed between the transparent plastic piece 102 and the second conformable member 120. In this implementation, the at least one first strap 124 may be affixed to the transparent plastic piece 102 and the first conformable member 1 16, and may be affixed the at least one second strap 130 to the transparent plastic piece 102 and the second conformable member 120.

[39] In some implementations where the at least one strap 124 and/or the at least one strap 130 are affixed to the front side 104 of the plastic piece 102, the at least one first strap 124 may be affixed to the front side 104 of the plastic piece 102 so as to be parallel to the top side 108, and the at least one second strap 130 may be affixed to the front side 104 of the plastic piece 102 so as to be parallel to the bottom side 1 10.

[40] The left side 1 12 and the right side 1 14 of the transparent plastic piece 102 may be unsealed, and/or may not have any parts attached to them, except at the points where they meet the top side 108 and the bottom side 1 10 of the transparent plastic piece 102 (e.g., where the first strap 124 and he second strap 130 are attached). Alternatively, the left side 1 12 and right cide 1 14 of the transparent plastic piece 102 may have cloth-like materials attached to them in a manner sufficient to protect the wearer from particulates or bacteria from entering the face mask 100.

[41] The at least one first strap 124 and the at least one second strap 130 may have a width of 0.2 inches to 2 inches. In some implementations, the width may be between 0.3 inches to 1 inch, or between 0.3 inches to 0.5 inches. The at least one first strap 124 and the at least one second strap 130 may have a thickness of 0.004 to 0.3 inches, or any suitable thickness. The ends 126 and 128 of the at least one first strap 124 may each be 12-16 inches (e.g., as measured from the left side 1 12 or the right side 1 14 of the transparent plastic piece 102). The ends 132 and 134 of the at least one second strap 130 may each be 12-16 inches (e.g., as measured from the left side 1 12 or the right side 1 14 of the transparent plastic piece 102). That is, the at least one first strap 124 and the at least one second strap 130 may have a length that allows a wearer to tie them to each other around the back of the head of the wearer. For example, ends 126 and 128 of the at least one first strap 124 may be tied together, and ends 132 and 134 of the at least one second strap 130 may be tied together. In some implementations, such as those discussed below

in connection with FIG. 1M, the at least one first strap 124 and the at least on second strap 130 may be connected to form first loop 124a and second loop 130a, or the first loop 124a and the second loop 130a may be formed from an elastic material. The first loop 124a and the second loop 130a may be of a sufficient length (e.g., 6 inches to 12 inches) so that they may be fitted behind a user's ears so as to affix the face mask 100 to the user's face.

[42] FIGS. 2A-2C show more detailed views of the first conformable member 1 16 shown in, for example, FIGS. 1 A, IB, ID, and IE.

In some implementations, the length 400 of the transparent plastic piece 102 be between 5 to 13 inches long, and in some implementations, between 6 and 12 inches long. The side portion 1 14 of the transparent plastic piece 102 may have a length 402, which may be 2.75 inches, or any other suitable length, such as between 2 to 7 inches. In some implementations, the length 402 may be between 2 to 6 inches wide, and in some implementations, between 3 to 5 inches. The side portion 1 12 of the transparent plastic piece 102 may have length that is similar to or the same as length 402. A length 404 between the top portion 108 and the bottom portion 406 of the transparent plastic piece 102 may be 3.75 inches, or any other suitable length, such as 2.5-5.5 inches. In implementations such as those shown in FIG. II, the length 404 may be increased when the face mask 100 includes an extension 102a for the plastic piece 102, as discussed below. A radius 406 of the bottom portion 1 10 of the transparent plastic piece 102 may be 7.8 inches, or any other suitable radius, such as 6-10 inches.

[50] The transparent plastic piece 102 and/or the extension 102a may be between 1 and 10 mils in thickness. In some implementations, the transparent plastic piece 102 and/or the extension 102a may be between 1 to 8 mils in thickness. In some implementations, the transparent plastic piece 102 and/or the extension 102a may be between 3 to 7 mils in thickness.
