Smart Vial with Ingestible Sensor for Remote Methadone Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methadone maintenance therapy (MMT) protocols face barriers such as geographical, time, and social constraints, particularly for patients with opioid use disorder, leading to inaccessible and unsafe take-home methadone regimens during the COVID-19 pandemic, resulting in increased overdose rates and diversion issues.
Innovation Solution
The R-MIST system integrates a smart connected medication vial with ingestible sensors and a digital health software platform for remote monitoring, allowing real-time tracking of methadone consumption, overdose detection, and remote therapy sessions, thereby eliminating the need for daily clinic visits while maintaining regulatory compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If directly observed methadone consumption is required, then patient safety is improved, but accessibility and convenience deteriorate
Solution Approach 1:
The patent replaces the mechanical system of direct observation (staff physically watching patients consume methadone in person) with an electronic monitoring system consisting of ingestible sensors, mobile devices, and remote communication infrastructure. The ingestible sensor detects consumption events and transmits data remotely, substituting physical observation with electronic monitoring while maintaining safety standards.
Solution Approach 2:
The patent introduces an intermediary monitoring system between the patient and the treatment provider. The mobile device and remote communication system act as intermediaries that transmit consumption data from the patient's environment to the treatment provider, eliminating the need for direct physical presence while ensuring compliance and safety.
2Reliability
If daily clinic visits are required, then medication adherence monitoring is improved, but time consumption and productivity deteriorate
Solution Approach 1:
The patent implements a self-service monitoring system where the patient's own mobile device and ingestible sensor automatically track and report medication consumption without requiring staff intervention. The system autonomously collects consumption data, transmits it to the treatment provider, and maintains adherence records, eliminating the need for staff to manually monitor each dose administration.
Solution Approach 2:
The patent establishes a continuous feedback loop where consumption data is automatically transmitted from the patient's mobile device to the treatment provider in real-time or near-real-time. This immediate feedback mechanism allows providers to monitor adherence continuously without requiring patients to physically return to the clinic, reducing time loss while maintaining reliable monitoring.
3Ease of operation
If take-home methadone is provided without monitoring, then accessibility is improved, but safety and diversion control deteriorate
Solution Approach 1:
The patent replaces the mechanical system of direct observation with electronic monitoring infrastructure. The ingestible sensor, mobile device, and remote communication system work together to monitor take-home methadone consumption electronically, allowing patients to receive medication at home while maintaining safety standards through automated tracking and provider oversight.
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
R-MIST provides a safe and accessible methadone treatment regimen by ensuring remote monitoring of medication adherence, reducing overdose risks, and offering supportive therapy, thus addressing the accessibility and safety concerns of traditional MMT protocols.
Implementation Method 1
When consumed, the ingestible sensor (IS) is activated by the patient stomach acid and transmits a signal to an IS-reader
Data Source
AI summary
A system and method to dispense and monitor a consumable. The system includes a vial configured to transmit at least one characteristic of contents within the vial to a remote location, unlock itself to enable a user to access and remove the contents in response to receipt of an unlock command, and to receive an ingestion confirmation signal when the contents are exposed to body fluids. The method includes determining whether to authorize dispensing of the contents to a patient from the vial, authorizing the dispensing of the contents from the vial, observing, by a clinician over a video conference, dispensing and consumption of the contents by the patient, receiving confirmation from an ingestion sensor that the patient consumed the contents.
