DESCRIPTION

(14) Referring to FIG. 1, an eye mask apparatus 10 for protecting a patient's eyes during dental or other radiography (i.e., “x-rays”) has an eye covering portion 12 including a lead vinyl sheet 14. The lead vinyl sheet 14 has a perimeter 16, and the perimeter 16 is configured such that the lead vinyl sheet 14 completely covers a patient's eyes (not shown). The coverage may, for example, be described as similar to, but is in no way limited by the coverage a typical sleep mask provides. Preferably, the coverage includes not only the patient's eyes, but the areas of the patient's face surrounding the patient's eyes. Alternatively, the coverage may be greater, covering a larger portion of the patient's face, including the patient's eyes.

(15) The eye covering portion 12, and thus the lead vinyl sheet 14 preferably includes a first side 18 and a second side 20 (FIG. 2). A trim portion 22 extends around the perimeter 16 of the lead vinyl sheet 14. The trim portion 22 is configured to wrap around the perimeter 16 of the lead vinyl sheet 14 both to protect perimeter 16, and to present a more aesthetically pleasing configuration of the eye covering portion 12. Preferably, the trim portion 22 wraps around the perimeter 16 and extends inward slightly over the first side 18 and the second side 20 to a first trim edge 24 on the first side 18 of the lead vinyl sheet 14, and a second trim edge 26 (FIG. 2) on the second side 20 of the lead vinyl sheet 14.

(16) Referring to FIG. 2, a retaining band 28 is provided and coupled to the eye covering portion 12. In one implementation, the retaining band 28 is coupled to the eye covering portion 12 at a first attachment point 30 and a second attachment point 32. The retaining band 28 may be coupled to both the lead vinyl sheet 14 and the trim portion 22 of the eye covering portion 12 for a more secure anchorage. The retaining band 28 is preferably of a size and tensile strength, such that it holds the eye covering portion 12 against the patient's eyes when the eye mask apparatus 10 is worn by the patient.

(17) Preferably, the lead vinyl sheet 14 may be made from a single unbroken sheet of a lead vinyl material. In some implementations, the trim portion 22 may be a fabric material to provide a softer covering around the perimeter 16 and a more aesthetic appearance to the eye mask apparatus 10. Whether the trim portion 22 is fabric or another material, it may be affixed to the lead vinyl sheet with stitching 34. The stitching 34 may extend entirely around the perimeter 16. Optionally, the stitching 34 may be configured to affix the trim portion 22 and the retaining band 28 to the lead vinyl sheet 14 at the first attachment point 30 and the second attachment point 32.

(18) FIGS. 3, 4, and 5 show a top view, a bottom perspective view, and a right side perspective view, respectively, of the eye mask apparatus 10. FIGS. 3 and 5 in particular illustrate how the trim portion 22 extends around the perimeter 16, and is sewn onto the lead vinyl sheet 14. As illustrated, the retaining band 28 is sewn under the trim portion 22 between the lead vinyl sheet 14 and the trim portion 22 to securely anchor it to the eye covering portion 12. In one implementation, the retaining band 28 may extend all the way to the perimeter 16 of the lead vinyl sheet 14.

Another alternative lead vinyl sheet 14 has a thickness of 3.62 mm, a lead equivalent value of 1.000 mm, and a weight of 14.08 kg/m.sup.2.

(22) Referring to FIG. 7, a second embodiment eye mask apparatus 110 is shown for protecting a patient's eyes during dental or other radiography. As discussed below, the second embodiment eye mask apparatus 110 has a reduced height, and is therefore presents a smaller area against a user's face. This results in the second embodiment mask apparatus 110 resting closer to the patient's eyes (not shown) when worn.

(23) Similar to the eye mask 10 shown in FIG. 1, the second embodiment mask apparatus 110 has an eye covering portion 112 including a lead vinyl sheet 114 that completely covers a patient's eyes. The coverage may, for example, be described as similar to, but is in no way limited by the coverage a typical sleep mask provides. In this embodiment, the coverage is specifically designed to cover the patient's eyes, generally from the patient's brow 204 (FIG. 12) to at or just above the user's cheeks 206 (FIG. 12), in the area defined by the patient's eye sockets (not shown).

(24) The eye covering portion 112, and thus the lead vinyl sheet 114 preferably includes a first side 118 and a second side 120 (FIG. 8). A trim portion 122 extends around the perimeter 116 of the lead vinyl sheet 114. The trim portion 122 is configured to wrap around the perimeter 116 of the lead vinyl sheet 114 both to protect the perimeter 116, and to present a more aesthetically pleasing configuration of the eye covering portion 112. Preferably, the trim portion 122 wraps completely around the perimeter 116 and extends inward slightly over the first side 118 and the second side 120 to a first trim edge 124 on the first side 118 of the lead vinyl sheet 114, and a second trim edge 126 (FIG. 8) on the second side 120 of the lead vinyl sheet 114.

(25) Referring to FIG. 8, a retaining band 128 is provided and coupled to the eye covering portion 112. In one implementation, the retaining band 128 is coupled to the eye covering portion 112 at a first attachment point 130 and a second attachment point 132. The retaining band 128 may be coupled to both the lead vinyl sheet 114 and the trim portion 122 of the eye covering portion 112 for a more secure anchorage. The retaining band 128 is preferably of a size and tensile strength, such that it holds the eye covering portion 112 against the patient's eyes (not shown) when the eye mask apparatus 110 is worn by the patient.

(26) Preferably, the lead vinyl sheet 114 may be made from a single unbroken sheet of a lead vinyl material. In some implementations, the trim portion 122 may be a fabric material to provide a softer covering around the perimeter 116 and a more aesthetic appearance to the eye mask apparatus 110. Whether the trim portion 122 is fabric or another material, it may be affixed to the lead vinyl sheet with stitching 134, shown also in FIG. 1. The stitching 134 may extend entirely around the perimeter 116. Optionally, the stitching 134 may be configured to affix the trim portion 122 and the retaining band 128 to the lead vinyl sheet 114 at the first attachment point 130 and the second attachment point 132.

(27) FIGS. 9, 10, and 11 show a top view, a bottom perspective view, and a right side perspective view, respectively, of the second embodiment eye mask apparatus 110. FIGS. 10 and 11 illustrate how the trim portion 122 extends around the perimeter 116, and is sewn onto the lead vinyl sheet 114. As illustrated, the retaining band 128 is sewn under the trim portion 122 between the lead vinyl sheet 114 and the trim portion 122 to securely anchor it to the eye covering portion 112. In one implementation, the retaining band 128 may extend all the way to the perimeter 116 of the lead vinyl sheet 114.

(28) FIG. 12 illustrates a user 200 wearing the eye mask apparatus 110 on the user's head 202 in preparation for a dental x-ray or other radiation treatment. As discussed, the lower profile second embodiment eye mask apparatus 110 more securely covers the patient's eyes (not shown) by securing against the user's 200 brow 204 and at or atop the user's cheeks 206.

(29) Referring to FIG. 13, one exemplary embodiment, the lead vinyl sheet 114 of the second embodiment eye mask 110 (FIGS. 7-12) has specific dimensions to promote close contact with the user's eyes and full coverage. The lead vinyl sheet 114 may have an overall width 136 of seven and three quarters (7¾) inches, and an overall height 138 of two and three eighths (2⅜) inches. In other embodiments, the width and height may be configured larger or smaller according to preference.

(30) In other exemplary embodiments, the lead vinyl sheet 114 may have a rounded left side 140 and a rounded right side 142. Although exemplary rounded patterns are shown, any shape sufficient to conform to the region around a user's eyes is contemplated. The rounded left side 140 and the rounded right side 142 preferably have a curvature radius of less than two inches. At various points around the left side 140 and the right side 142, the circumference of the curvature radius may be divided into segments, for example, 1/16 inch, ⅛ inch, 7/16 inch, and 13/16 inch, according to preference.

(31) Still referring to FIG. 13, in the illustrated embodiment, the top 144 of the lead vinyl sheet 114 is flat, although other shapes are contemplated to effectively engage a user's brow. A nose recess 146 is provided at the bottom 148. The nose recess 146 preferably has a nose recess height 150 of approximately one (1) inch. It may have an opening width 152 of approximately two (2) inches. The rounded upper portion 154 of the nose recess 146 may have a curvature radius of 7/16 inches, while the transition from the nose recess 146 to the bottom 148 of the lead vinyl sheet 114 of the second embodiment eye mask 110 may have a curvature radius 156 of approximately one half (½) inch. As with the left side 140 and the right side 142 of the second embodiment eye mask 110, these values are exemplary in nature, and other contemplated embodiments may have different measurements.
