Medication Transfer System for Precise Dosage Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients face challenges in preparing and administering medication due to lack of guidance, complexity in measuring dosages, and concerns about medication stability and child access, especially with mail-order dispensing.
Innovation Solution
A medication transfer system comprising a drug chamber, dose chamber, and transfer module that allows for precise measurement and transfer of liquid medication, with child-resistant features and measurement markings, enabling easy and accurate dosage preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mail order dispensing is used, then patient convenience is improved, but guidance on preparation and administration is insufficient
Solution Approach 1:
The system enables patients to independently prepare and administer medication through an automated device that guides them through the process. The patient loads the medication container, selects dosage parameters, and the device automatically transfers the correct amount, eliminating the need for pharmacy staff assistance while providing built-in guidance through the interface and measurement markings.
Solution Approach 2:
The automated medication preparation device acts as an intermediary between the medication container and the patient. It receives the medication container, processes the medication through controlled transfer mechanisms, and delivers the prepared dosage, thereby providing guidance and control that would otherwise require pharmacy staff intervention.
2Ease of operation
If patients prepare dosages themselves, then pharmacy visits are reduced, but measuring dosages becomes complex and difficult
Solution Approach 1:
The device performs the complex measurement and transfer operations automatically once the patient loads the container and selects dosage parameters. The patient does not need to understand or perform complex measuring tasks; the system handles the complexity internally through automated pump mechanisms and controlled transfer processes.
Solution Approach 2:
The system replaces manual measurement methods (such as using measuring cups or spoons) with an automated pump and transfer mechanism. The pump automatically transfers precise volumes of medication based on electronic controls and pre-programmed dosage parameters, eliminating the need for patients to perform complex manual measuring tasks.
3Measurement precision
If measurement devices are provided, then dosage accuracy is improved, but coordination and mobility requirements increase
Solution Approach 1:
The system combines the measurement device, transfer mechanism, and administration container into a single integrated unit. The measurement markings are built into the device, the pump mechanism is incorporated, and the transfer process is automated, eliminating the need for patients to coordinate multiple separate devices or perform complex manual operations.
Solution Approach 2:
The device performs the measurement and transfer operations automatically based on electronic controls and pre-programmed parameters. The system self-regulates the transfer process, eliminating the need for patients to manually coordinate measurement devices with their physical capabilities.
4Reliability
If child-resistant features are added, then medication safety is improved, but device complexity increases
Solution Approach 1:
The child-resistant features are integrated into the container and device components rather than added as separate external mechanisms. The container incorporates child-resistant closure features, and the device includes access controls that are built into the overall structure, thereby providing safety functionality without significantly increasing overall device complexity.

AI summary
Supplying a medication for use with a medication delivery system includes supplying a liquid medication composition into an interior volume of a drug chamber and dispensing the drug chamber to a patient or caregiver. The drug chamber may include a fitting for coupling to a corresponding fitting of a transfer module and a drug port. The transfer module may also include a transfer port configured to align with the drug port when the drug chamber and transfer module are coupled at their fittings. The transfer module may be operable to open the drug port to allow transfer of a portion of the liquid medication composition through the transfer port into a separate dose chamber.
