Pre-Marked Medication Dosing Label for Pediatric Emergency Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug administration systems in emergency and critical care situations, particularly for pediatric patients, are prone to errors due to the complexity of dosage calculations and selection processes, leading to inaccuracies and inefficiencies.
Innovation Solution
A pre-marked medicine dosing device with color-coded zones corresponding to predetermined drug doses based on patient characteristics, such as length, and a method for generating and applying dosing labels to simplify the administration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional weight-based dosing methods are used, then drug dosage can be determined, but the process becomes complex and error-prone due to multiple calculation steps and lack of readily available weighing equipment in emergency situations
Solution Approach 1:
The patent changes the basis for dosage determination from patient weight to patient length. This parameter substitution simplifies the dosing process in emergency situations where weighing equipment is unavailable, while maintaining dosage accuracy through the established relationship between length and appropriate drug dosage for pediatric patients
Solution Approach 2:
The medicine dosing device is pre-marked with dosage zones corresponding to different patient length ranges before use. This preliminary preparation eliminates the need for complex calculations during emergency administration, as the appropriate dosage zone is already determined and visually marked on the device
2Measurement precision
If multiple calculation steps are performed to determine correct drug dosage, then dosage can be determined, but the time required increases and error risk increases due to the multitude of steps
Solution Approach 1:
The device is pre-marked with dosage zones that correspond to patient length ranges and appropriate drug dosages. This preliminary configuration allows the practitioner to simply match the patient's length to the corresponding zone on the device, eliminating multiple calculation steps and reducing administration time while maintaining accuracy
Solution Approach 2:
The patent extracts the complex calculation steps from the dosing process and replaces them with a simplified visual matching process. The dosage determination is reduced to a single step of comparing patient length against the pre-marked zones on the device, removing unnecessary intermediate calculations
3Ease of operation
If constant incremental change in dosages is used, then dosing system is simple, but dosing accuracy is lost in critical situations requiring precise dosage adjustments
Solution Approach 1:
The dosing device is divided into multiple discrete dosage zones, each corresponding to a specific patient length range and appropriate dosage. This segmentation allows for precise dosage selection based on the patient's actual length, rather than using constant incremental changes that may not match the specific clinical requirements

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.
