Description

"FACE PROTECTOR"

BACKGROUND OF THE INVENTION

1. Field of the Invention

Th e p re s ent i nvent i on re l a t ed t o a f a ce pr o t e c t or comprising a combination of an eye shield and a face mask, and more particularly to a disposable eye shield which can be effectively attached to and combined with a disposable, surgical face mask and used as a composite structure to protect both phys ician and patient f rom the poss ibl e transmiss ion of infectious disease.

2 . General Background

With the advent of communicable diseases such as AIDS, it is possible to transmit diseases to innocent victims such as physicians and their assistants by the accidental splattering of blood during surgical procedures, for example, into the eyes of the surgeon or assistant. Since the blood may be contaminated, any covering which would be provided for the eyes, or the face in general should be disposable to avoid the likelihood of spreading the disease from contaminated material which remains on eye coverings in the event the article is reused.

Although medical-type personnel, for example doctors, dentists, nurses, paramedics," etc., have used the surgical mask to protect both the wearer and the patient from communicable diseases, there is no known device which is effective in protecting the entire face of the wearer. Hence, an object of the present invention is to provide a shield which covers the eyes and which includes sealing members which contact the body portion around the eyes for preventing blood from splattering into the eyes, which can be effectively combined with a face mask to form a disposable composite structure which protects the entire face of the user.

Another object of the present invention is to provide an eye shield-face mask combination which is inexpensive and easy to make so that its cost will be low.

A further object of the present invention is to provide combination eye protector-face mask which gives total fac protection in the operating room, emergency room, laboratory, dental office, clinic, and in emergency medical law enforcemen and in rescue and public safety operations.

Still another object oif the present invention is t provide a protective eye shield per se which is effective i protecting the eyes from contamination.

Other objects and advantages of the present invention wil become apparent from a consideration of the following detaile description and drawings. SUMMARY OF THE PRESENT INVENTION

The total face protection medical device of the presen invention comprises an eye shield and a face mask. The ey shield according to the present invention includes an elongate transparent flexible member having integral symmetrical space planar surfaces joined by an integral narrowing webbed portion

The extent that the webbed portion narrows depends on the desig of the eye shield. Elongated sealing members are sealabl attached to the interior surface of the flexible member alon its upper edge and its lower edge. Although an adjustable ban

(not shown) can be included at the sides of the flexible membe for holding the flexible member in position with the plana portions curved and covering the eyes of the user advantageously, when the face mask is attached to the ey shield, the band attachment for the face mask is sufficient t hold both the face mask and the eye shield in place on the fac of the wearer.

The face mask which can be used in the total face protecto of the present invention can be any of the commonly used fac masks presently used by medical-type personnel since it is onl necessary that the eye shield is attachable to the face mask

The disposable face mask is generally made of a soft comfortable, non-irritating inner and outer facing materia which possesses excellent breathability and lightweigh construction which insures air permeability, even for extende periods of time. It is frequently pleated to provide a larg facial pocket for keeping the mask away from the mouth and nos of the user for maximum comfort. One or more ties or elasti bands, which may be adjustable in length, extend from the side of the mask in order to secure the face mask to the face of the user. Frequently, a contour bar, that is, a flexible strip, for example a flexible aluminum nosepiece is sealed inside the mask at the top edge of the mask in order to insure security and provide a superior fit. Of course, the bottom edge of the mask can also be provided with such a flexible strip. In one type of construction, the face mask is a two layer construction which utilizes a nonwoven outer layer to resist shedding and a soft, comfortable, hypo-allergenic inner layer.

The eye shield which is used in the total face protector of the present invention is a transparent flexible member which is provided with a cushion material, for example a foam strip which extends across the top edge of the eye shield and a similar cushion material or foam strip which extends across the bottom edge of the eye shield. The foam strip can be made of any type of thin plastic foam material, such as for example a polyurethane foam, open and closed cell sponge rubber, cross linked polyethylene foam, cork, sheet rubber, and the like. The foam strips provide comfort for the user and also serve to effectively seal the eyes from possible contamination. The foam strip at the top of the eye shield is provided with adhesive on one side and thus is adhesively attached to the top of the flexible eye shield. The foam strip or strips provided at the botto of the eye shield contains an adhesive on both sides o the foam strip. Thus the adhesive on one side of the foam stri fixes the foam to the eye shield and the adhesive on the othe side of the foam strip is used to fix the strip and the flexibl eye shield attached thereto to the top of the face mask. Thus, for example, the face mask is first attached to the face of th user, and then protective release liners which cover th adhesive surface of the foam strip at the bottom of the ey shield are removed and the shield is adhesively attached to th top of the face mask. Since the eye shield is of a flexible, light construction, it readily conforms to the contour of th face of the user.

The eye shield utilized in the present invention can als be provided with slots on the lateral sides thereof so that i the user wears glasses, templets of the glasses can exten through the lateral slots for engagement with the ears. Thus in operation, the eye glasses are always on the outside of th eyeshield.

The optically clear eye shield of the present inventio combines the features of being nonfogging, nonglare nondistortion and spatter resistant whereby a fluid repellen disposal on the shield. causes fluids to bead up. The eye shiel is a one-piece construction which is comfortable, breathable an possesses a 95%-plus bacterial filtration efficiency. The flexible eye shield member is a crystal clear, colorless polyester based film, VISTEX-PS, manufactured by Film

Specialists, Inc., Whitehouse, New Jersey, having a permanent anti-fog coating such as that described in U.S. Patent No.

4,467,073 or other similar anti-fog coating. The film has thickness of 0.0015 inches and its coating is a two-par reactive urethane coating which prevents fogging under all temperature-humidity conditions by causing water droplets t spread, rather than form beads which appear as fog. The fil has a scratch resistance which is superior to untreate plastics. Superficial scratches that do appear will heal themselves when moistened by rinsing with water or even b breathing on the film. The film is not affected by freezing, o by temperatures as high as 250 degrees Fahrenheit and it coating will not become soft when wet and will not smudge.
