PROBLEM TO BE SOLVED: To provide an ophthalmic device adapted for single use and change of a medicament and suited for administration of the medicament.SOLUTION: A medicament administration assist tool 10 has a pool 19a capable of storing a medicament defined by an upper eyelid conjunctiva fornix 26e and an upper side 14a when mounted, an aperture of the pool 19a being closed by an upper eyelid conjunctiva 26a and a surface of the eyeball which serve as a lid. In addition, a pool 19b capable of storing the medicament is defined by a lower eyelid conjunctiva fornix 26f and a lower side 14c, and an aperture of the pool 19b is closed by a lower eyelid conjunctiva 26b and a surface of the eyeball which serve as a lid. The medicament administration assist tool 10 has a shape, as a whole, of a round-cornered rectangle sides 14a-14d of which are convexed in an arch shape. At the center of the medicament administration assist tool 10 is formed a through-hole 12 to make an opening in a cornea region.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】 薬剤の使い切りや変更等への対応及び薬剤の供給に好適な眼用器具を提供する。【解決手段】 薬剤供給補助具１０は、装着時に上眼瞼結膜円蓋部２６ｅ及び上辺１４ａにより、薬剤を貯留可能なプール１９ａが区画され、上眼瞼結膜２６ａ及び眼球の表面が蓋となってプール１９ａの開口が閉鎖される。また、下眼瞼結膜円蓋部２６ｆ及び下辺１４ｃにより、薬剤を貯留可能なプール１９ｂが区画され、下眼瞼結膜２６ｂ及び眼球の表面が蓋となってプール１９ｂの開口が閉鎖される。また、薬剤供給補助具１０は、平面形状が全体として、角丸矩形の各辺１４ａ～１４ｄが弓形凸部となる形状となっている。薬剤供給補助具１０の中央には、角膜領域を開口する貫通孔１２が形成されている。【選択図】 図２
