Pre-Marked Medication Dosing for Length-Based Emergency Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug administration methods, particularly in emergency and critical care situations, are prone to errors due to multiple steps and reliance on inaccurate weight-based dosage calculations, leading to potential overdosing and inefficiencies, especially in pediatric patients.
Innovation Solution
A pre-marked medicine dosing device with color-coded zones corresponding to patient physical characteristics, such as length, and a method for determining and administering precise drug doses using these zones, reducing the need for complex calculations and device selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If weight-based dosage calculation method is used, then drug dosage can be determined, but it leads to overdosing and requires scale availability which is not practical in emergency situations
Solution Approach 1:
The patent changes the basis parameter for dosage calculation from patient weight to patient length. This is achieved by providing dosing devices with markings that correspond to patient length measurements, eliminating the need for weight-based calculations and scale availability while maintaining dosage accuracy.
2Reliability
If multiple steps are involved in drug administration process, then proper drug selection and dosage determination can be achieved, but it increases the potential for errors and reduces efficiency
Solution Approach 1:
The patent combines multiple separate functions into a single integrated dosing device. The device integrates patient length measurement reference, dosage calculation, and drug administration markings into one unified tool, eliminating the need for separate calculation steps and reducing error potential while improving administration efficiency.
Solution Approach 2:
The patent incorporates pre-calculated dosage information and markings on the dosing device itself. This preliminary preparation of dosage data eliminates the need for real-time calculations during emergency administration, reducing steps and improving both reliability and productivity.
3Device complexity
If constant incremental change in dosages is used, then dosing system is simple, but it results in loss of needed dosing accuracy
Solution Approach 1:
The patent segments the dosing device into multiple zones with different incremental changes based on patient length ranges. Each zone has optimized increment values that provide appropriate precision for that specific range, allowing the device to maintain simplicity while achieving high dosage precision across different patient sizes.

AI summary
Aspects of the present disclosure disclose a system for delivering medication. In one aspect, the disclosure is directed a medical dispensing device that includes a label with a series of zones of varying widths, with each of the zones corresponding to a pre-determined volumetric dose of the drug that is correlated to one of the physical characteristics of a patient. In one specific example, the label is further affixed to the medicine dispensing device such that the smallest dose of the drug to be administered corresponds to a first zone that is proximate an opening through which the drug is to be dispensed.
