Integrated Drug Dispensing Device for Controlled-Dose Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively address medication adherence, particularly for controlled substances, and are inadequate in preventing diversion and abuse, while also being costly and inefficient in clinical trials.
Innovation Solution
A reusable dispensing device with networked communication capabilities that tracks and authenticates individual doses of controlled substances using unique identifiers, integrates with hospital and clinical trial systems, and includes a disposable cartridge for monitoring and deactivating unused doses to deter diversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional medication packaging and monitoring systems are used, then device complexity is low, but medication adherence is poor and diversion cannot be prevented
Solution Approach 1:
The system divides medication management into discrete tracked units (individual doses or vials) with unique identifiers. Each unit is monitored independently through the dispensing device, which tracks when and how medications are accessed. This segmentation enables precise adherence monitoring without requiring complex continuous monitoring of the entire medication supply.
Solution Approach 2:
The dispensing device serves multiple functions: it stores medications, tracks adherence events, prevents diversion through authentication mechanisms, and interfaces with clinical trial systems. By consolidating these functions into a single device, the system improves reliability without proportionally increasing complexity.
2Object-affected harmful factors
If comprehensive monitoring systems are implemented to track controlled substances, then diversion prevention is improved, but loss of time and operational efficiency decrease
Solution Approach 1:
The system performs preliminary authentication and tracking setup when medications are loaded into the dispensing device. Unique identifiers are registered and baseline adherence patterns are established before potential diversion can occur. This preliminary action enables real-time detection without requiring time-consuming investigations later.
Solution Approach 2:
The system provides immediate feedback when unauthorized access or diversion attempts are detected through authentication failures or unexpected access patterns. This real-time feedback enables rapid response to prevent diversion while maintaining operational efficiency through automated alerts rather than continuous manual monitoring.
3Measurement precision
If manual tracking methods are used for clinical trials, then cost is low, but measurement precision and data accuracy are insufficient
Solution Approach 1:
The system replaces manual tracking methods with automated electronic monitoring. The dispensing device automatically records adherence events, timestamps access, and transmits data to clinical trial systems. This substitution of mechanical/manual processes with electronic automation improves measurement precision while the standardized data collection reduces overall trial costs through efficiency gains.
Solution Approach 2:
The system creates digital copies of adherence data and medication tracking information that can be transmitted and stored without physical handling. These digital records provide precise measurement of adherence while eliminating the costs associated with manual data collection, verification, and storage.
4Reliability
If secure authentication systems are implemented for each dose, then reliability against abuse is improved, but ease of operation decreases
Solution Approach 1:
The system implements preliminary authentication checks that prevent unauthorized access before abuse can occur. The dispensing device requires verification of patient identity and authorization before releasing medications, creating a barrier against abuse while maintaining ease of operation for legitimate users through streamlined authentication processes.

AI summary
In one embodiment, a device includes a plurality of vials each bearing a unique identifier and in discrete locations in the device and an alignment assembly for aligning one of the discrete locations with an access point for dispensing one of the plurality of vials. Computer instructions select a vial of the plurality of vials to be dispensed and inventory information of the plurality of vials is stored, including unique identifiers and a status for each vial. Instructions can deactivate dispensing of the vials based on a signal from an environmental sensor. A deactivation assembly deactivates dispensing of the vials based on the instructions.
