Eye Drop Applicator With Cavity For Precise Medication Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eye drop application techniques often fail to accurately deliver medication into the conjunctival sac, leading to ineffective treatment and medication wastage.
Innovation Solution
An eye drop applicator with a main body and upper portion cavity designed to securely hold a predetermined amount of medication, featuring a removable cap for protection and a finger-receiving opening with variable diameter to ensure accurate and natural application, utilizing surface tension and capillary action for delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional eye drop application techniques are used, then the application process is simple, but the medication delivery precision is poor
Solution Approach 1:
The applicator serves as an intermediary device between the medication bottle and the eye. It includes a cavity that receives a predetermined amount of medication from the bottle, then delivers it precisely to the eye. The cavity acts as a mediator that controls the transfer and positioning of the medication drop, ensuring accurate delivery into the conjunctival sac while the user simply places the applicator in their mouth.
2Loss of substance
If conventional eye drop application is used, then no special device is needed, but medication wastage occurs
Solution Approach 1:
The applicator cavity is pre-configured to receive and hold a predetermined amount of medication before application. This preliminary preparation ensures that the exact required dose is measured and retained in the cavity, preventing both under-dosing and over-dosing. The user places the applicator in their mouth, the cavity fills with the precise amount needed, and any excess remains in the cavity rather than being wasted.
3Reliability
If conventional eye drop application is used, then the process is quick, but treatment effectiveness is reduced
Solution Approach 1:
The applicator cavity acts as a mediator that ensures reliable medication delivery by controlling the transfer from bottle to eye. It positions the medication precisely at the intended delivery location, ensuring it enters the conjunctival sac correctly. This intermediary function guarantees treatment effectiveness while the quick mouth-placement mechanism maintains speed.

AI summary
An eye drop applicator includes a main body with a lower portion and an upper portion having a cavity configured to retain a predetermined amount of medication. The lower portion may include an opening configured to snuggly receive a user's finger and/or a top of a medication bottle. The eye drop applicator may also include a removable cap configured to attach to the upper portion of the main body to cover the cavity.
