Description

Surgical anti-fog mask with anti-fog wall {SURGICAL ANTI-FOG MASK WITH A VAPOR BARRIER}

The present invention relates to a mask, and more particularly to an anti-fog mask that reduces or eliminates the fog that may occur when wearing glasses or eye protection equipment worn by the wearer of the mask.

The mask can be used for various purposes. For example, a surgical mask is worn when performing surgery or the like by a surgeon or related persons to prevent contamination or infection of suspended bacteria in the air emitted from the wearer's breath. Surgical masks are generally lightweight, unique in structure, and may have multiple functions depending on the wearer's function.

The surgical mask consists of a rectangular surgical mask body (not shown) of corrugated or non-creased material, and a deafness attached to one side of the mask and a deafness attached to the other side. The earpiece may be designed to fit the wearer's ear. In this way, the surgical mask is configured and provided to fit the wearer's face to prevent contaminants from entering the exterior due to inhalation and release when the wearer inhales and exhales.

One type of mask is patented in the United States (5,699,792), a mask with an enhanced face seal granted to Barumann et al. On December 23, 1997.

Although the mask is designed to suit a variety of face shapes of the wearer, it is not easy to prevent the wearer's breath from being discharged between the wearer's face and the surgical mask. Since these masks are not designed to prevent fogging when breathing through the mouth, some breathing may be vented through the bottom of the mask to the vicinity of the wearer's eyes. Warm, moist breathing keeps fluid vapors from condensing in cold water easily. Such a cold object may be in an air-conditioned room in the form of a glass lens of an optical aid used by surgeons and assistants. Such optical aids include spectacles, surgical magnifying glasses, and surgical microscopes.

Exhaust of the breath is somewhat hindered by the surgical mask itself, but in the state of wearing the surgical mask, it is promoted to rise upward. Because warm air rises, the wearer's breathing tends to naturally rise upward through the upper surgical mask surface area, which causes fogging near the optical aid located near the wearer's eye when wearing the surgical mask. .

Therefore, it obstructs the vision of the wearer and in some cases is dangerous. This drawback of prior art masks is often inconvenient to remove the lens in order to remove the fogging of the lens which obstructs the wearer's field of view. In order to secure clear vision and save time during the surgical procedure, there is a need to prevent fogging.

The present invention has been made to solve the above technical problem, an object of the present invention is to provide an anti-fog mask that is convenient to breathe, and prevents the fogging of the user's eyes or glasses.

The material is made of 90.33% polyester with 78 denier texture and 9.67% 40 denier lycra spandex. This material is cut into thin members and due to the nature of the material the strip may be "rolled over". That is, the edges may be warped. In this way, an elastically deformable member having a semicircular cross section can be formed to provide some comfort behind the wearer's ear.

The nature of the tie or ear canal (41, 50L, 50R, 40L, 40R, 50LP and 50RP) allows attachment using thermal bonding techniques such as radio frequency (RF) heat coupling. Given the present invention, those skilled in the art will recognize that the use of synthetic fabrics, such as the lycra spandex / polyester fabrics of the present invention, allows the use of high frequency thermal adhesion techniques to attach the fabric to other synthetic fabrics.

It will also be appreciated that thermal bonds cannot be used with conventional rubber or thread coated rubber distances because their structural integrity can be destroyed. In addition, those skilled in the art will find that the earpieces made of lycra spandex / polyester fabric according to the present invention have more "flexibility" than conventional rubber or thread coated rubber earpieces, and are conveniently used by wearers with sensitive skin behind the wearer's ears. There is a number.

According to one embodiment of the invention, in order to attach the ear 41 and 40L to the point 60, it is necessary to apply an appropriate amount of heat and pressure. The band or bands used at the ear to support the surgical mask on the wearer's face may include a combination of elastic components and fibrous thermoplastic components. It provides some elastic properties to the band and the strap can be constructed by the application of heat and pressure.

Generally, the width of the band used to filter the face mask ranges from about 1/16 inch to 1 inch, typically about 1/8 to 1/2 inch. The most common band used with a filtering face mask is about 3/16 to 1/4 inch wide. However, it is not limited thereto. The width of the band can vary.

The width of the band can be adjusted by varying the number of threads when tying the band. For example, six threads can typically provide a wider band than a band with only four threads of the same size. The width and thickness of the band can be adjusted using threads of different sizes. Screws with larger diameters or cross sections will generally provide thicker and wider screws than screws with smaller diameters or cross sections. Similarly, the width and thickness of the band can be adjusted using various sizes of fibrous thermoplastic yarns. However, it is not limited to this.

In one embodiment of the present invention, the band having the elastic component and the thermoplastic component is permanently attached to the surgical mask body by applying heat and pressure to the point where the band and the body are adjacent. The combination of heat and pressure is generally sufficient to partially or fully melt a portion of the band and / or a portion of the surgical mask body, thus creating a bond between the tie, ear or band. Depending on the structure of the surgical mask body, the outermost layer may or may not be part of the surgical mask body that melts. Rather, in some embodiments, the inner layer of the surgical mask body, for example the filtering material, may be a melting layer.

Earpieces, ties or bands may be formed from various types of materials. Earrings and / or ties are preferably formed from bonded polypropylene having a 1.5 to 1.65 oz basis weight per square yard. This particular type of material may be ultrasonically welded, stitched or thermocompressed in various patterns to provide elastic fastening means used to attach the tie or ear to the surgical mask body 20.

1 to 6, the surgical mask 10 may include a surgical mask body 20 and an antifog wall 30. The anti-fog wall 30 is positioned between the mouth and nose of the wearer's face to prevent passage of vapor, for example between the surgical mask 10 and the wearer's face. When the anti-fog wall 30 is positioned between the wearer's nose and mouth, as shown in FIG. 1, moisture from breathing may be used in a surgical manner in a manner that causes the wearer's face protection device, such as glasses or goggles, to cause fog. Leaving the mask is prevented.

The antifog wall 30 may help induce exhalation through the layer of the surgical mask, the layer of the mask body portion and into the space created on the side of the mask where the mask portion and the face of the wearer are not in sealing contact.

The foregoing is specific embodiments for practicing the present invention. The present invention will include not only the above-described embodiments but also embodiments that can be simply changed in design or easily changed. In addition, the present invention will also include techniques that can be easily modified and practiced using the embodiments.
