Color-Coded Syringe Holder for Faster Pediatric Dose Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug administration methods in emergency and critical care situations, particularly for pediatric patients, are prone to errors due to the complexity of the dosing process and reliance on inaccurate weight-based or other patient characteristic systems, leading to potential dosing inaccuracies and inefficiencies.
Innovation Solution
A medicine dispensing device with color-coded zones corresponding to predetermined drug doses based on patient characteristics, accompanied by a method for generating dosing labels and administering drugs using pre-marked devices to ensure accurate and efficient dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional weight-based dosing methods are used, then dosing can be performed, but dosing accuracy deteriorates due to complexity and potential for errors
Solution Approach 1:
The syringe holder is segmented into multiple color-coded zones, each representing a specific dose volume. This segmentation allows the user to quickly identify the correct dose by matching the patient's weight category to the corresponding colored zone, eliminating complex calculations and reducing dosing errors.
Solution Approach 2:
Different portions of the syringe holder have different visual characteristics (colors) corresponding to different dose volumes. Each color-coded zone provides localized visual information that helps the user quickly determine the correct dose without needing to perform calculations, thereby improving dosing accuracy while reducing process complexity.
2Productivity
If multiple steps are involved in drug administration, then dosing can be performed, but efficiency deteriorates due to the number of steps required
Solution Approach 1:
The syringe holder is pre-marked with color-coded zones that correspond to predetermined dose volumes. This preliminary preparation allows the user to directly select the correct dose by visual matching without needing to perform calculations or multiple measurement steps, significantly improving administration efficiency and reducing time loss.
Solution Approach 2:
The complex calculation process is extracted and replaced by a simple visual matching process. The user only needs to match the patient's weight category to the corresponding color-coded zone on the syringe holder, eliminating the need for mathematical calculations and reducing the number of steps required for drug administration.
3Measurement precision
If color-coded zones are added to the syringe holder, then dosing accuracy improves, but device complexity increases
Solution Approach 1:
The syringe holder incorporates color-coded zones with different visual characteristics at different positions. Each color represents a specific dose volume, providing localized visual verification that improves dosing accuracy. The added visual elements are integrated into the existing syringe holder structure, minimizing the increase in overall device complexity.

AI summary
A syringe holder for facilitating dispensing of medication to a patient from a syringe. The syringe holder includes a cylindrical housing configured to be attached to a barrel portion of the syringe. A first visual dosing aid on a surface of the cylindrical housing is of a first color and has a plurality of first dosing segments where the first color is correlated to a first patient size. Each of the first dosing segments identifies a volume of the medication corresponding to a first medication dose. A second visual dosing aid on a surface of the cylindrical housing is of a second color and has a plurality of second dosing segments where the second color is correlated to a second patient size. Each of the second dosing segments identifies a volume of the medication corresponding to a second medication dose.
