Smart Inhaler Sensor System for Automated Medication Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for recording and managing patient medication status are often manual, making it difficult to accurately grasp and record medication adherence, particularly in conditions like asthma treatment.
Innovation Solution
An information processing system comprising an acquisition unit to gather medication action information, an analysis unit to identify predetermined actions related to medication execution, and a generation unit to generate medication information, utilizing a wearable device and cloud-based management for automated data capture and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual recording and reporting by patient is used, then device complexity is reduced, but measurement precision of medication status deteriorates
Solution Approach 1:
The inhaler device automatically detects and records medication actions through its own sensors (acceleration, angle, pressure) without requiring patient manual reporting. The device serves itself by autonomously monitoring its own usage state, eliminating the need for patient memory and manual entry while maintaining high recording accuracy.
Solution Approach 2:
The patent replaces manual mechanical recording (patient writing down medication status) with automated electronic sensing and data processing. Sensors detect inhaler usage mechanically and electronically, and a microprocessor analyzes this data to automatically determine medication status, substituting human manual operations with automated electronic systems.
2Reliability
If automated detection system is implemented, then medication status monitoring accuracy is improved, but device complexity increases
Solution Approach 1:
The inhaler device integrates multiple functions into a single unit: it serves as both the medication delivery device and the monitoring device. The same inhaler that delivers medication also contains sensors and processing units to detect usage, making the device universal and eliminating the need for separate monitoring equipment.
Solution Approach 2:
The patent introduces an intermediary communication interface (wireless transmission unit) that connects the inhaler to external devices like smartphones or medical systems. This intermediary enables reliable data transmission without requiring direct complex integration between all system components, simplifying the overall architecture while maintaining monitoring reliability.
3Loss of information
If manual recording method is used, then ease of operation is maintained, but loss of information occurs
Solution Approach 1:
The inhaler automatically detects and records all medication actions without requiring patient intervention for data collection. The device monitors its own usage patterns, ensuring complete information capture while maintaining ease of operation for the patient who simply needs to use the inhaler normally without additional recording steps.
