Medication Dispensing Device with Load Cell Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medication management solutions, such as pill sorters, require manual sorting and tracking, making it difficult for patients to comply with complex medication regimens, and caregivers lack visibility into patient adherence, affecting the assessment of medication effectiveness.
Innovation Solution
A medication dispensing device with trays equipped with load cells for weight measurement and a user interface that provides instructions, allowing for automated tracking of medication access and dispensing, ensuring accurate dosing and compliance monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual sorting and tracking methods are used, then device complexity is reduced, but patient compliance and tracking accuracy deteriorate
Solution Approach 1:
The system enables self-service through automated weight measurement and tracking. The load cells automatically detect medication removal without human intervention, and the processor autonomously updates compliance records, eliminating the need for manual sorting and tracking while improving reliability
Solution Approach 2:
Manual mechanical sorting and tracking is replaced with an automated electronic system. Weight-based detection using load cells substitutes for manual counting and recording, while the processor and user interface provide automated compliance monitoring, significantly improving reliability without requiring complex manual procedures
2Loss of information
If automated tracking systems are implemented, then compliance monitoring improves, but device complexity increases
Solution Approach 1:
The system implements feedback through the user interface, which provides real-time information to patients and caregivers about compliance status. The processor continuously monitors weight changes and communicates compliance information through the user interface, ensuring visibility without requiring overly complex systems
Solution Approach 2:
The processor serves multiple functions: it monitors weight changes, tracks compliance, manages medication schedules, and communicates with the user interface. This multi-functionality reduces the need for separate dedicated components, improving compliance visibility while controlling device complexity
3Measurement precision
If weight measurement is used to track medication, then measurement precision improves, but device complexity increases
Solution Approach 1:
Manual medication counting and measurement is replaced with automated weight measurement using load cells. This substitution provides precise measurement of medication mass without requiring complex manual procedures, achieving high measurement precision with relatively simple electronic components
Solution Approach 2:
The load cells perform self-service by automatically measuring medication weight without human intervention. The system autonomously detects mass changes and triggers compliance tracking, improving measurement precision while maintaining simple device architecture
4Adaptability or versatility
If multiple trays are used for different medications, then adaptability improves, but device complexity increases
Solution Approach 1:
The medication storage system is segmented into multiple independent trays, each capable of holding different medications. This segmentation allows the system to accommodate diverse medication regimens while keeping each individual tray relatively simple in design, balancing adaptability with manageable complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device simplifies medication management by automating tracking and dispensing, enhancing patient compliance and caregiver oversight, reducing errors and improving regimen effectiveness.
Implementation Method 1
each tray including a load cell configured to measure a mass of a medication (e.g., by weight) contained in the respective tray
Data Source
AI summary
A medication dispensing device may include a plurality of trays, each tray optionally including a load cell configured to measure a mass/weight of a medication contained in the respective tray. Each tray is placeable in a medication accessible position and a medication inaccessible position. The medication dispensing device includes a user interface configured to provide instructions and/or other information with regard to access for each medication. A processor provides instructions to selectively place each tray in the medication accessible position, and to determine, based on any change in the mass of the medication placed in the medication accessible position, whether the appropriate amount of the medication is removed from the tray.
