Description

  The present invention relates to an eye cover for measuring a visual field by covering an eye so as to be able to blink in a state where light is blocked and when examining a visual field.

  Conventionally, in order to inspect a visual field, one eye is covered with gauze and the other eye's visual field is measured, and then the other eye is covered with gauze and one eye's visual field is measured. The gauze must not cross the nasal bridge, be able to blink under the gauze, and the nose side and lower ear side must be completely shielded in order to enable accurate measurement during this visual field inspection. Is a necessary condition.

  It is relatively easy to apply the gauze to the eyes so as to satisfy this condition, but in order to stick the gauze in that state, several pieces of adhesive tape are previously attached to the surface of the gauze, and this Since both ends of the adhesive tape that protrude from the outer periphery of the gauze must be attached to the skin around the eyes, the work is time-consuming, and the gauze position must be shifted and reapplied. There was a problem that a necessary inspection occurred and smooth inspection could not be performed.

On the other hand, although it is not for visual field inspection, as described in Reference 1, for example, a pressure-sensitive adhesive is layered on one side as a light-blocking eye cover for performing light-blocking treatment such as a child's strabismus. An eye covering pad that is slightly smaller than the supporting sheet is attached to the supporting sheet, and a release paper is placed on the outer peripheral portion of the pressure sensitive adhesive of the supporting sheet exposed from the outer peripheral edge of the eye covering pad. A structure having a structure in which an eye cover pad is covered with the release paper is known.

  However, when the eye cover configured as described above is employed for visual field inspection, it can be attached so that the support sheet does not cross the nasal bridge and the nose side and lower ear side are completely shielded, The pressure sensitive adhesive on the outer periphery of the support sheet that protrudes from the outer edge of the eye cover pad is adhered around the eye to fix the eye cover pad to the eye socket, making it impossible to blink, making it unsuitable for visual field inspection. is there. Further, since the outer peripheral portion of the pressure-sensitive adhesive layered on the outer peripheral portion of the support sheet is exposed from the outer peripheral end of the eye cover pad over the entire periphery, the upper end of the support sheet is increased when the support sheet is enlarged. There arises a problem that the pressure-sensitive adhesive on the side portion adheres to the eyebrows and is difficult to use.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to ensure that the eye can be blinked and the outside light can be reliably blocked when inspecting the visual field. An object of the present invention is to provide an eye cover for inspection such as a visual field that can be easily and accurately covered.

  In order to achieve the above object, the eye covering for inspection of the visual field or the like according to the present invention is formed in a size capable of covering the entire periphery of the eye including the eyebrows and has an adhesive on the entire surface of one side as described in claim 1. A support sheet provided with a layer, a light-shielding eye cover pad provided with an eyebrow covering protrusion at the upper end, and a release paper covering the eye cover pad, the outer periphery of the eye cover pad The eye cover pad is stuck on the center part of the support sheet in a state where the outer peripheral part of the adhesive layer other than the eyebrow covering protruding edge part is exposed from the end, and is exposed from the outer peripheral end of the eye cover pad. It has a structure in which the release paper having an eye cover pad covered on the outer peripheral portion of the pressure-sensitive adhesive layer of the support sheet is detachably attached.

  In the eye cover for inspection such as a visual field configured as described above, the invention according to claim 2 is characterized in that the support sheet is formed of a horizontally long elliptical shape or a horizontally long elliptical shape flexible fabric or a synthetic resin film. The covering pad is formed of a horizontally long oval or horizontally long oval non-woven fabric that is slightly smaller than the support sheet or a cloth thicker than the support sheet. An eyebrow-covered protruding edge portion having a shape that can be covered is projected.

  According to the eye cover for inspection of the visual field and the like of the present invention, the support sheet is formed in a size capable of covering the entire periphery of the eye including the eyebrows and is provided with an adhesive layer on the entire surface, and the eyebrows cover on the upper end portion. It consists of a light-shielding eye cover pad provided with a protruding edge part and a release paper covering the eye cover pad, and the adhesive layer other than the eyebrow-covered protruding edge part from the outer peripheral end surface of the eye cover pad. Since the eye cover pad is attached to the center of the support sheet with the outer periphery exposed, the support sheet with the adhesive layer on the entire surface covers the entire periphery of the eye, including the eyebrows. Despite being formed in a possible size, the adhesive layer part at the upper end facing the eyebrows is concealed by the eyebrow covering protrusion of the eye covering pad, so it does not adhere to the eyebrows, Cover the eyebrows with the eyebrow covering protrusion of the covering pad, One by the adhesive layer of the other peripheral edge portion can be in the state of blocking light or the like to adhere to the eye.

  Furthermore, the position where the adhesive layer of the support sheet is attached to the periphery of the eye can be easily and reliably set by making the eyebrow covering protrusion of the eye cover pad face the eyebrows and overlapping the eyebrow. It is possible to cover the eye with the support sheet and the eye cover pad quickly and accurately, and the support sheet is sized to cover the eyebrows with the eye at the center, so the eye cover pad can blink Thus, the eye can be formed in a size and shape that can cover the eye, and the visual field and the like can be inspected smoothly and accurately. In addition, since the support sheet covers the eyebrows through the eyebrow covering protrusions of the eye cover pad without adhering to the eyebrows, the eye sheet is covered with the eye cover pad after the inspection of one eye. The support sheet can be easily peeled off from the other eye side and used for the examination of the other eye.

  In this case, since the eye covered with the eye cover pad was covered so as to be able to blink without being pressed by the eye cover pad as described above, the eye cover pad is peeled off to remove the eye. When the inspection is performed, it is possible to immediately measure an accurate visual field without taking time.

  According to the invention of claim 2, the support sheet is formed of a horizontally long oval shape or a horizontally long oval flexible fabric or a synthetic resin film, while the eye cover pad is slightly turned from the support sheet. An eyebrow-covered protruding edge formed from a fabric that is thicker than a small oblong or oblong non-woven fabric or support sheet, and capable of covering the entire eyebrows upward on the upper edge of the eye-cover pad Since the projections are provided, both sides of the semicircular shape of the support sheet are bent and deformed along the shape of the upper side of the nose and the outer side of the nose, so that there is no gap from the heel without causing wrinkles. Thus, it is possible to accurately stick to a tension state where blinking can be achieved, to improve the light blocking property, and to perform an accurate inspection smoothly.

  Next, a specific embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 3, an eye cover for visual field inspection includes a support sheet 1 having a pressure-sensitive adhesive layer 2 layered on the entire surface. An eye cover pad 3 integrally bonded to the center of the mold surface of the support sheet 1 via the pressure-sensitive adhesive layer 2 and a support projecting outward from the outer peripheral edge of the eye cover pad 3 The sheet 1 is composed of release papers 4a and 4b that are detachably attached to the pressure-sensitive adhesive layer 2 on the outer periphery of the sheet 1 and cover the eye cover pad 3.

  The support sheet 1 is made of a thin cloth having flexibility, a synthetic resin film, or a non-woven fabric such as paper, and covers the entire periphery of the eye including the eyebrows B above the eye A as shown in FIG. It is formed in a possible size, specifically, a horizontally long oval shape or a horizontally long oval shape having a major axis of 85 mm and a minor axis of about 70 mm. On the other hand, the eye cover pad 3 adhered on the pressure-sensitive adhesive layer 2 of the support sheet 1 is made of a non-woven fabric or fabric thicker than the support sheet 1 and is slightly longer than the support sheet 1 in a horizontally long oval shape or horizontally long. A horizontally elongated rectangular eyebrow covering projection 3a having a size capable of covering the entire eyebrow B upward is formed in the center in the width direction at the upper end of the oblong shape. ing.

  Then, with the upper end surface of the eyebrow covering projecting edge 3 a aligned with the center of the upper end surface of the support sheet 1, the eyebrow covering projecting edge 3 a is the adhesive layer 2 at the upper end of the outer periphery of the support sheet 1. Attached to the top and supported with the outer peripheral part of the other adhesive layer 2 exposed from the outer peripheral edge of the eye covering pad 3 other than the eyebrow-covered protruding edge part 3a by a width of about 10 mm. An eye cover pad 3 is stuck on the adhesive layer 2 in the center of the sheet 1. That is, the outer peripheral portion of the support sheet 1 excluding the upper end portion to which the eyebrow covering protruding edge portion 3 a of the eye cover pad 3 is stuck is protruded outward from the outer peripheral end of the eye cover pad 3.

  Note that the eye cover pad 3 is entirely covered with the support sheet 1 from the surface facing the support sheet 1 to the outer peripheral end surface, that is, the central portion of the support sheet 1 to which the eye cover pad 3 is attached. The eye cover pad 3 is adhered to the pressure-sensitive adhesive layer 2 in a state where it is depressed by a depth corresponding to the thickness of the support sheet 1. Therefore, the exposed surface of the eye cover pad 3 and the eye cover pad 3 are attached. It forms so that the adhesive layer 2 of the outer peripheral part of the support sheet 1 which protrudes from the outer peripheral end may be flush.

  The release papers 4a and 4b are formed in the same shape, the same size and the same shape as the upper half and the lower half of the support sheet 1, respectively, and are provided with overlapping margins 4a1 and 4b1 at opposite ends, respectively. The outer peripheral part excluding the end part is detachably attached to the upper half part and the lower half part of the adhesive layer 2 on the outer peripheral part of the support sheet that is exposed outward from the outer peripheral edge of the eye cover pad 3, The overlap margins 4a1 and 4b1 facing each other are overlapped to cover the entire eye covering pad 3.

  The release papers 4a and 4b are detachably attached to the upper half and the lower half of the support sheet 1, respectively. The shape and size of the right half and the left half of the support sheet 1 are provided. The right half portion and the left half portion of the support sheet 1 may be entirely covered so as to be peelable.

  In order to sequentially inspect the visual field of both eyes using the thus configured eye cover, first, as shown in FIG. 2, the eye cover pad 3 is covered and protected by the release papers 4a and 4b. After the release papers 4a and 4b are peeled to expose the entire eye cover pad 3 as shown in FIG. 1, the eyebrow covering protruding edge 3a formed on the upper end of the eye cover pad 3 is placed on one side. In the outer peripheral part of the support sheet 1 provided with the pressure-sensitive adhesive layer 2 that is applied to the eyebrows B of the eye A and covers the eyebrows B and is exposed in the circumferential direction from both ends of the eyebrows covering protruding edge 3a. 4. As shown in FIG. 5, the adhesive layer 2a of the inner part facing the nose side is attached to the opposite side surface at the upper end of the nose raised from the inner end of the eye A, and the outer part facing the ear side The adhesive layer part 2b is adhered onto the skin on the outer side of the orbit of the eye A, and the lower adhesive layer part 2c is further removed from the orbit of the eye A. It is stuck on the facial skin of square section.

  At this time, since the support sheet 1 is formed in a horizontally long oval shape or a horizontally long oval shape that can cover the entire periphery of the eye including the eyebrows B, the eyebrow covering protrusion 3a of the eye covering pad 3 is overlaid on the eyebrows B. Just by aligning, the convex arc-shaped portion of the support sheet 1 projecting from the inner edge of the eye cover pad 3 toward the nose side follows the surface shape of the side surface of the nose without crossing the nose ridge (midline of the nose). The convex arc-shaped portion of the support sheet 1 that protrudes from the outer end of the eye cover pad 3 toward the ear side can be accurately adhered without causing wrinkles while being bent. It can be securely attached to the outer skin facing the natural surface.

  When the support sheet 1 is attached to the periphery of the eye in this way, the eye cover pad 3 covers the eyebrows B with the eyebrow covering protrusion 3a on the upper end side, and the lower end protrudes from the orbital portion of the eye A. It is located on the face part below the orbit, and the both sides of the convex arc are pasted on the side surfaces of the nose and the skin surface on the ear side that are raised from both sides of the eye socket of the eye A. Thus, the surface facing the eye A is stretched away from the eyelid, so that the eye A can be covered with the eye covering pad 3 so that blinking is possible.

  Thus, after one eye A is covered with the eye cover pad 3 and the visual field of the other eye A is examined, the support sheet 1 to which the eye cover pad 3 is adhered is peeled off from the periphery of the eye. Then, the outer peripheral portion of the adhesive layer 2 protruding from the outer peripheral edge of the eye cover pad 3 in the support sheet 1 is stuck around the other eye A in the same manner as described above, and the eye cover pad 3 applies the eye. A is covered, and the visual field of one eye A is inspected. After the visual field inspection of both eyes is performed in this manner, the eye cover is discarded, and a new eye cover is used for the next inspection.

  6 to 8 show modified examples of the eye cover for inspection such as the visual field of the present invention. In the above embodiment, the eyebrow covering rim formed integrally with the upper end of the eye cover pad 3 is shown. Although the shape of 3a is formed in a horizontally long rectangular shape, the eye cover shown in FIGS. 6 to 8 has the upper periphery of the eye cover pad 3 formed in a horizontally long oval shape or a horizontally long oval shape upward. It is formed on the eyebrow covering protruding edge portion 3a which is protruded and has both end faces formed in a convex arc shape continuous with the convex arc-shaped both end faces of the eye covering pad 3.

  And the adhesive layer 2 of the outer peripheral part of the support sheet 1 is exposed from the outer peripheral end of the eye cover pad 3 other than the said eyebrows covering projecting edge part 3a formed in the magnitude | size which covers the eyebrows B entirely. At the same time, the eyebrow covering protruding edge 3a is adhered to the adhesive layer 2 on the upper peripheral side of the support sheet 1 in the same manner as in the above embodiment to cover the entire surface of the adhesive layer 2 and to support the upper end surface thereof. The sheet 1 is covered with release papers 4a and 4b in a state of being flush with the upper end surface of the sheet 1. The support sheet is such that the surface of the eye cover pad 3 that covers the eye A and the adhesive layer 2 on the outer periphery of the support sheet 1 exposed from the outer periphery of the eye cover pad 3 are flush with each other. An eye cover pad 3 is attached to 1.

  When the visual field is inspected by the inspection eye cover such as the visual field configured as described above, after peeling the release papers 4a and 4b as described above, the eyebrows B are formed by the eyebrow covering protruding edge 3a as shown in FIG. The adhesive layer part 2a of the inner part facing the nose side is coated on the outer peripheral side part of the support sheet 1 provided with the adhesive layer 2 that is coated and exposed in the circumferential direction from both side ends of the eyebrow covering protruding edge part 3a. Is attached to the opposite side surface of the upper end of the nose raised from the inner end of the eye A, the adhesive layer portion 2b of the outer portion facing the ear side is attached to the skin on the outer side of the eye A, and further The lower adhesive layer 2c is applied from the orbit of the eye A onto the facial skin in the lower part so that the eye A is covered in a state where blinking is possible, and the examination is performed in this state. Note that the eye cover of the present invention can be used as an eye cover for measuring visual acuity or for blocking ultraviolet rays in addition to visual field inspection.
