Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard syringes pose challenges for individuals with diminished eyesight and caregivers due to difficult calibration markings, potential for inaccurate dosages, and risk of distraction leading to incorrect insulin administration.
Innovation Solution
A syringe template with a substantially opaque exterior and transparent windows, featuring a high-visibility color-coded plunger stopper that glows in the dark, allowing for easier measurement and administration of precise medication doses by indicating the correct volume through calibrated windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard syringe calibration markings are used, then the syringe can measure medication volume, but the markings are difficult to discern for persons with diminished eyesight
Solution Approach 1:
The patent applies color changes by using a transparent or translucent template with calibrated windows that allow light transmission, creating high-contrast visual indicators. The template may incorporate color-coded sections or light-reactive materials that enhance the visibility of the plunger position and medication volume, making it easier for persons with diminished eyesight to discern measurement markings.
Solution Approach 2:
The template acts as an intermediary device between the syringe barrel and the user's vision. It provides a magnified, high-contrast view of the plunger position through calibrated windows, mediating the difficult-to-see calibration markings into clearly visible indicators that facilitate accurate measurement reading.
2Measurement precision
If standard syringe markings are used, then dosage can be measured, but the user may be unfamiliar with dosage calculations and uncertain when the required dosage has been drawn
Solution Approach 1:
The template segments the continuous syringe barrel view into discrete, calibrated measurement windows. Each window represents a specific dosage increment or target volume, dividing the complex task of reading continuous markings into simpler, segmented visual cues that are easier to interpret and reduce calculation errors.
Solution Approach 2:
The template uses color-coded windows or color contrasts to indicate different dosage levels or target volumes. This visual coding system provides intuitive, immediate recognition of the required dosage without requiring the user to perform calculations or interpret standard numerical markings.
3Productivity
If the user draws medication into the syringe, then the medication is prepared for injection, but the user may be distracted and draw an inaccurate amount
Solution Approach 1:
The template provides immediate visual feedback through its calibrated windows that indicate whether the correct dosage has been drawn. The high-contrast view and clear visual cues allow the user to verify the plunger position and medication volume in real-time, providing feedback that confirms accurate dosing or alerts to errors before injection occurs.
Solution Approach 2:
The template is pre-calibrated with windows positioned to indicate correct dosage levels before the user begins drawing medication. This preliminary setup of visual guides allows the user to stop drawing medication precisely when the plunger aligns with the calibrated window, eliminating the need for post-drawing verification or correction.
4Difficulty of detecting and measuring
If a template with opaque exterior and transparent windows is used, then visibility of the plunger and dosage is improved, but the device complexity increases
Solution Approach 1:
The template is designed as a disposable component that can be discarded after single use, eliminating the need for cleaning, sterilization, or complex assembly/disassembly procedures. This disposable nature reduces the operational complexity despite adding a component to the syringe system, as users simply attach the template, use it once, and discard it.

Function Achieved in This Case
Enhances visibility and accuracy of medication dosing, simplifies the process for both visually impaired users and caregivers, reducing the risk of over or under-administration, and ensuring reproducible dosages under various lighting conditions.
Implementation Method 1
at least one substantially transparent window in the substantially opaque exterior permitting a view of the syringe barrel and a distal end of a plunger within the barrel of the syringe
Implementation Method 2
The distal end of the plunger may be configured to glow in the dark

AI summary
An apparatus and method for improving medication dosing is provided. The apparatus preferably includes a template configured to fit over a barrel of a syringe, the template having a substantially opaque exterior and at least one substantially transparent section in the substantially opaque exterior permitting a view of the syringe barrel and a distal end of a plunger within the barrel of the syringe. A method includes the steps of positioning a dosing template on a syringe, operating a plunger within the syringe, and drawing a predetermined dose of medication into the syringe.
