Inhaler Sensor Monitoring for Pre-Emptive Asthma Risk Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current asthma management systems lack effective tools for real-time monitoring and predicting asthma-related rescue events, leading to suboptimal treatment and increased healthcare costs due to uncontrolled symptoms and frequent exacerbations.
Innovation Solution
An asthma analytics system that tracks rescue medication usage through sensors on inhalers, analyzing geographical and temporal data alongside environmental conditions to provide real-time risk assessments and notifications to patients and healthcare providers, using machine learning to predict and mitigate future asthma rescue events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If periodic questionnaires are used to monitor asthma control, then patients can report their symptoms and inhaler usage, but the information is delayed and subject to recall bias, preventing real-time monitoring and prediction of rescue events
Solution Approach 1:
The patent replaces manual questionnaire-based self-reporting with an automated electronic monitoring system. Sensors embedded in inhalers automatically detect and transmit usage events, and mobile applications automatically collect environmental and symptom data, eliminating the need for patients to manually recall and report information while providing real-time monitoring.
Solution Approach 2:
The system enables automatic self-monitoring where the inhaler device itself tracks its own usage events, and the mobile application automatically gathers environmental data and symptom information without requiring active patient recall or manual entry, thus eliminating time delays and recall bias.
2Measurement precision
If patients manually report symptom frequency and inhaler usage through questionnaires, then providers can assess asthma control, but the data is inaccurate due to recall bias and different interpretations of symptoms
Solution Approach 1:
The patent replaces subjective manual reporting with objective automated sensing. Inhaler sensors automatically detect and record usage events with precise timing and dosage information, while mobile applications automatically capture environmental data and symptom severity scores, eliminating the distortion caused by recall bias and varying symptom interpretations.
Solution Approach 2:
The system provides continuous feedback loops where sensor data from inhalers and environmental sensors is automatically transmitted to both patients and providers, enabling real-time monitoring and immediate feedback that improves measurement precision and eliminates the information loss associated with delayed self-reporting.
3Productivity
If physicians use written questionnaires to monitor patients, then asthma control can be assessed, but the process is complex and time-consuming, requiring patients to accurately recall and report over the past two to four weeks
Solution Approach 1:
The system automates the data collection process by having inhalers self-track usage events and mobile applications self-gather environmental and symptom data without requiring patients to manually recall or report information over past periods, thereby simplifying the monitoring process and improving efficiency.
Solution Approach 2:
The patent replaces the complex manual questionnaire process with automated electronic sensing and transmission systems. Inhaler sensors automatically detect and transmit usage events, and mobile applications automatically collect and transmit environmental and symptom data, eliminating the time-consuming manual reporting process while maintaining comprehensive monitoring capabilities.
4Adaptability or versatility
If patients are provided with information about environmental triggers and factors, then they can better manage their symptoms, but identifying and monitoring multiple triggers is a complex task not currently feasible for many patients and providers
Solution Approach 1:
The patent implements a universal monitoring platform where a single mobile application can track multiple environmental triggers and factors simultaneously. The system integrates data from various environmental sensors, inhaler usage records, and patient symptom reports, providing comprehensive multi-factor monitoring that simplifies the management of multiple triggers through a unified interface.
Solution Approach 2:
The mobile application serves as an intermediary that automatically collects, stores, and analyzes environmental trigger data and patient responses. This intermediary system processes complex multi-factor relationships and presents simplified actionable insights to both patients and providers, making comprehensive trigger monitoring feasible without requiring manual analysis of multiple variables.
Data Source
AI summary
This description provides asthma risk notifications in advance of predicted rescue usage events in order to help effect behavior changes in a patient to prevent those events from occurring. Rescue medication events, changes in environmental conditions, and other contextually relevant information are detected by sensors associated with the patient's medicament device/s and are collected from other sources, respectively, to provide a basis to determine a patient's risk score. This data is analyzed to determine the severity of the patient's risk for an asthma event and is used to send notifications accordingly.
