  Moreover, in the said embodiment and its modification, although the through-hole 12 was formed as a hole which opens a cornea area | region, it is not restricted to this, Arbitrary numbers, arbitrary sizes, arbitrary shapes, arbitrary locations Can be formed. For example, the through-hole 12 can be formed as a hole that opens at least a pupil region (a region located in the pupil 22 at the time of wearing), or can be opened in the surface direction of the medicine supply assisting tool 10. For example, the modification of FIG. 7 is also employable.

FIG. 7 is a front view of the medicine supply assisting tool 10.
Since the amount of movement of the eyeball is larger in the left-right direction than in the up-down direction, from the viewpoint of reducing the possibility or degree of interference with the cornea 24, as shown in FIG. The length of the through hole 12 may be larger than the height (length in the vertical direction) of the through hole 12. From the same point of view, since the upward and downward movement amount of the eyeball is larger in the upward direction than in the downward direction, the length from the reference point O located at the center of the cornea 24 facing the front at the time of wearing in the through-hole 12 to the upper end.

Considering these two points, the through-hole 12 has, for example, a horizontally long oval shape in which the upper portion expands (a shape in which the width is larger than the height and the length from the reference point O to the upper end is larger than the length to the lower end). A configuration can be employed. In this case, when the medicine supply assisting tool 10 rotates on the surface of the eyeball due to the movement of the eyelid or the eyeball, the relative position of the through-hole 12 with respect to the cornea 24 changes, and thus the medicine supply assisting tool 10 may rotate. Alternatively, from the viewpoint of reducing the degree, for example, the medicine supply assisting device 10 is such that the upper edge of the medicine supply assisting device 10 is positioned (contact or close) to the upper lid conjunctiva cap and the lower edge is positioned to the lid conjunctiva cap. A configuration for setting the size of 10 can be adopted.

  Moreover, in the said embodiment and its modification, although the hole 12 was formed as a through-hole, it is not restricted to this, The recessed part (The case where one part or all part becomes a bottom is included.) It is the same below. Or a recess having an opening on the rear surface (hereinafter collectively referred to as “a recess”). This is because when the component of the medicine 40 permeates the medicine supply aid 10 by diffusion or the like, it does not necessarily have to penetrate. Further, the hole 12 itself may not be provided.

  Moreover, in the said embodiment and its modification, although the chemical | medical agent supply auxiliary tool 10 had the area | region located in the conjunctiva (eyelid conjunctiva or bulb | ball conjunctiva) on the back side of the eyelid at the time of wearing, it is not limited to this, and it is not limited to this. It can also be configured to have a circular lid region (a region located in the conjunctival circular lid when mounted). Thereby, the chemical | medical agent 40 can be mounted | worn with the conjunctival wrap part area | region.
