Description

  The present invention belongs to the technical field of eye drop assisting devices, and in particular, eye drop assisting devices that can reliably drop a drug solution onto the eyeball.

  In general, when instilling by himself, the medical solution is dropped by moving upward, moving the eye drop container directly above the eyeball, and pressing the eye drop container with a finger. Even if it is an inexperienced person, it is difficult to drop the liquid medicine onto the eyeball properly even if it seems that the eye drop operation seems simple. In order to facilitate such instillation, various structures such as eye drop containers and auxiliary tools have been studied.

  For example, the following Patent Document 1 is an eye drop container having a main part portion for storing a chemical solution and a chemical solution port for dropping the chemical solution, and at the time of instillation, it is visually recognized that the chemical solution port is substantially directly above the eyeball. It has a visual recognition part. The visually recognizing part has a bottom part on the side of the chemical liquid port, and a sub container part having a predetermined volume is arranged at a position surrounding the chemical liquid port. The sub-container part contains a predetermined amount or more of a transparent and colored liquid that covers at least the bottom part when the chemical solution port is substantially directly above. Whether or not the chemical is horizontal can be determined from the amount of light that passes through the transparent and colored liquid.
