Medication Delivery Contact Sensor for Automatic Adherence Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of non-adherence to medication regimens by patients, particularly in outpatient care, is significant due to lack of effective monitoring methods that do not rely on patient effort, leading to increased healthcare costs and reduced oversight.
Innovation Solution
A system comprising an enclosure, contact sensor, and controller that monitors the state of connection of a medication delivery device to indirectly track fluid flow without contacting the fluid, using an enclosure that can attach to the device and a contact sensor to detect electrical connection changes, with a controller relaying this information to indicate adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional monitoring methods (house visits and phone calls) are used to monitor patient adherence, then patient adherence can be monitored, but time and resources are consumed and effectiveness is limited
Solution Approach 1:
The system enables self-monitoring of medication adherence through automatic detection of medication dispensing events. The medication delivery device itself generates and transmits adherence data without requiring patient effort to log or report usage, eliminating the need for manual monitoring by healthcare providers while maintaining high accuracy in adherence tracking.
Solution Approach 2:
The patent replaces manual monitoring methods (house visits and phone calls) with an automated electronic monitoring system. The system uses sensors, controllers, and communication modules to automatically detect, record, and transmit medication adherence data, substituting the mechanical human monitoring process with an automated technological system that consumes minimal resources.
2Measurement precision
If non-adherent patients are required to do extra work to monitor adherence, then adherence monitoring is possible, but effectiveness is reduced because non-adherent patients typically do not follow extra directions
Solution Approach 1:
The system is designed to automatically monitor adherence without requiring any action from the patient beyond taking their medication as prescribed. The device autonomously detects dispensing events, records timing and dosage information, and transmits data to healthcare providers, making the monitoring process effortless for patients while maintaining high accuracy.
Solution Approach 2:
The patent introduces an intermediary monitoring system that acts as a bridge between the patient and healthcare provider. This intermediary device automatically captures adherence data and relays it to providers, eliminating the need for patients to directly engage in monitoring activities while ensuring accurate data transmission to those who need the information.
3Loss of energy
If outpatient care proportion is increased to reduce healthcare costs, then healthcare cost efficiency is improved, but oversight and monitoring capability is reduced
Solution Approach 1:
The system implements continuous feedback loops where adherence data is automatically collected by the medication delivery device, transmitted to healthcare providers, and used to inform clinical decisions. This real-time or near-real-time feedback mechanism enables remote monitoring of outpatient patients, maintaining high oversight capability while supporting the shift toward cost-efficient outpatient care models.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides objective verification of medication adherence with minimal patient effort, allowing for timely interventions and reducing healthcare resource inefficiencies by monitoring fluid flow paths in medication delivery devices.
Implementation Method 1
The contact sensor is disposed within the enclosure and configured to monitor a state of electrical connection
Data Source
AI summary
Systems, devices, and methods described herein indirectly monitor a state of fluid flow by monitoring a state of connection of a medication delivery device. The system includes an enclosure, a contact sensor, and a controller. The enclosure can attach around at least a portion of an outer surface of the medication delivery device to enclose at least a portion of the outer surface therein. The contact sensor and controller are enclosed within the enclosure. The contact sensor can monitor a state of electrical connection. The controller is in communication with the contact sensor and can relay the state of electrical connection. The state of connection of the contact sensor corresponds to the state of connection of the medication delivery device.
