Description

Mask with transparent plastic sheet

Background

During events such as surgery and other medical, dental, etc., health professionals often wear face masks to protect the wearer and surrounding parties from infection. The face mask is designed to capture droplets and aerosolized particles from the mouth and nose of the wearer and to prevent bodily fluids and other airborne liquids from reaching the covered portion of the wearer's face. Masks are typically made of paper or other non-woven material, and usually have three layers (i.e., three panels). Typically, these layers are composed of meltblown material disposed between non-woven fabrics. The meltblown material acts as a filter to prevent contaminants from entering or exiting the mask. Most masks include folds or creases that expand the surface area of the mask so that the mask covers the area of the wearer's face from the nose to the chin. Masks for surgical treatment typically have four straps tied behind the head. Other variations include masks that attach 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 elastic head straps placed behind the head.

Detailed Description

Communication errors are a major cause of medical errors. The potential for communication errors is particularly increased in deaf and hearing impaired medical patients when using standard face masks such as surgical masks. It is estimated that approximately 55% of communications are linguistically. Standard surgical masks block the wearer's face and prevent others from observing the mask wearer's facial expressions and reading the wearer's lips. Implementations of the disclosed subject matter can provide a mask with full-face visibility. The mask may provide protection for the wearer and may provide comfort and breathability to the wearer. The mask of the disclosed subject matter may allow patients and other individuals to observe more of the wearer's face and facial expressions, while the mask may provide safety, comfort, and breathability to the wearer.

While many people may benefit from full face communication, this is particularly important for the following subjects: deaf and hearing impaired patients, medical personnel, medical students, laboratory technicians and scientists; patients with limited english levels; sign language translation and personnel; dentists, dental hygienists, and other dental health professionals; patients who are prone or experiencing stress and anxiety; a pediatric patient; immunosuppressed patients; a cancer patient; HIV/AIDS patients; an organ transplant recipient; medical personnel who cannot vaccinate seasonal influenza vaccine and must wear a mask; and to enable medical personnel to view the face of a colleague and better understand all medical personnel in the case of a conversation in a dental and/or medical environment (such as an operating room) and/or in a noisy environment. People in non-medical environments who use masks may also benefit from full-face communication.

Implementations of the disclosed subject matter can 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 anti-fog coating to provide full-face visibility. The mask may include features that provide comfort and breathability.

Implementations of the disclosed subject matter can provide a mask having a clear plastic sheet and/or an extended plastic sheet, and a conforming member attached to the back side of the plastic sheet. The plastic sheet may provide improved visibility to the entire face of the wearer of the mask so that others may observe all facial expressions and/or movement of the lips of the wearer. The plastic sheet may act as an impermeable barrier to air and/or other particles and may provide enhanced protection compared to conventional masks made from cloth-like materials. The conforming member of the mask may provide a better fit, reduced slippage, increased stability, and/or increased breathability for the wearer of the mask as compared to conventional masks. The conforming member can push the clear plastic sheet away from the wearer's face and/or lips to prevent the wearer's face and/or lips from touching the clear plastic sheet and/or to increase comfort and breathability by allowing air to flow in and/or out from the sides of the mask and/or the back side of the mask. That is, the conforming member may seal the top and bottom of the mask and/or create a "pocket" for airflow with the plastic sheet by preventing airflow to and/or from the top and/or bottom of the mask.

Fig. 1A-1M illustrate diagrams of a mask 100 in accordance with implementations of the disclosed subject matter. In particular, fig. 1B shows a view of the back side of the mask 100 of fig. 1A, including a compliant member attached to a portion of the back side. Fig. 1C shows a side view of the mask 100, and fig. 1D shows a top view of the mask 100. Fig. 1E shows another view of the back side of the mask 100 of fig. 1B, including a first and second conforming member attached to portions of the back side. Fig. 1F shows a view of the front side of the mask 100. Fig. 1G-1K illustrate different views and implementations of a mask 100 including an extension that accommodates a plastic sheet over a component. Fig. 1L shows a mask 100 having a single compliant member, and fig. 1M shows an implementation of the mask 100 having straps forming first and second loops.

The face mask 100 of fig. 1A-1M may include a transparent sheet of plastic 102, the transparent sheet of plastic 102 having a front side 104, a back side 106, a top side 108, a bottom side 110, a left side 112, and a right side 114. The transparent plastic sheet 102 of fig. 1A-1M is shown in greater detail and is described below in conjunction with fig. 4. In some implementations, the transparent plastic sheet 102 may include extensions 102a as shown in fig. 1G-1K, described below. The extensions 102a may cover the eyes and/or upper head area of the wearer. In some implementations, the viewing area of the transparent plastic sheet 102 and/or the extension 102a may be translucent, opaque, etc. The transparent viewing area of the transparent plastic sheet 102 and/or the extension 102a may be coated with an anti-fog or anti-fog coating to provide full-face visibility, wherein the coating may prevent water from condensing on the surface of the mask in the form of small droplets like fog. That is, the anti-fog or anti-fog coating may minimize moisture accumulation on the back side 106 of the transparent plastic sheet 102 and/or the extension 102a (e.g., moisture accumulation from the breathing of the wearer of the mask 100).

The first conforming member 116 can be attached to a first portion 118 of the back side 106 of the transparent plastic sheet 102 and arranged parallel to the top side 108 of the transparent plastic sheet 102.
