Solution Overview
Problem
Drug delivery devices, such as inhalers, face challenges in ensuring proper drug delivery and patient adherence due to non-physiological factors, and the integration of electronics introduces technical challenges like durability, reliability, and power management.
Innovation Solution
Incorporating an electronics module in drug delivery devices that includes sensors to track usage conditions, a communication circuit to send data to external devices, and a power management system to optimize battery life, while using a QR code or other machine-readable code to facilitate software downloads specific to the device and medication type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronics module is added to track usage conditions and improve adherence monitoring, then patient adherence and compliance are improved, but device complexity increases
Solution Approach 1:
The electronics module is designed to perform multiple functions: tracking usage conditions, storing data in memory, communicating with external devices, and providing patient feedback. This multi-functionality allows a single component to address various aspects of adherence monitoring, thereby improving reliability without proportionally increasing overall device complexity
Solution Approach 2:
The patent introduces an external device (such as a smartphone or computer) that serves as an intermediary between the inhaler's electronics module and the patient/physician. The external device handles complex data processing, storage, and analysis tasks, allowing the inhaler's electronics module to remain relatively simple while still achieving comprehensive adherence monitoring
2Adaptability or versatility
If a local power source is added to support electronic components, then functionality is improved, but size and weight of the portable device increase
Solution Approach 1:
The power management system is designed to provide power only when needed for specific electronic functions (tracking, communication, display) rather than continuously. The system activates the electronics module selectively based on usage events, thereby reducing the power capacity requirements and allowing for a lighter battery while maintaining necessary functionality
Solution Approach 2:
The electronics module operates in periodic cycles, alternating between active states (when tracking or communicating data) and low-power sleep states. This periodic operation pattern reduces average power consumption, enabling the use of smaller, lighter battery components while still supporting all required electronic functions
3Loss of information
If sensors and communication mechanisms are integrated into the device, then data tracking capability is improved, but power consumption increases
Solution Approach 1:
The system continuously tracks usage conditions through sensors integrated into the inhaler, but implements intelligent data management by only transmitting processed adherence information to external devices when relevant (e.g., after a dosing event or when the device is connected to a smartphone). This approach maintains continuous monitoring capability while reducing overall power consumption by eliminating unnecessary continuous communication
Solution Approach 2:
The patent extracts the heavy computational and communication tasks from the inhaler itself and relocates them to an external device. The inhaler's electronics module performs only essential local functions (sensing, basic data storage), while the external device handles complex data processing, analysis, and communication, thereby significantly reducing the power consumption requirements of the portable inhaler
Data Source
AI summary
A system may be configured for sending a Uniform Resource Locator (URL) request based on a location of an external device (502). An inhaler (100) may include medicament, an electronics module (120), and/or a Quick Response (QR) code (160). An external device may determine a URL and/or a medicament type of the inhaler (100) based on the QR code (160). The external device may send an indication of the medicament type and/or a location indication to a server that hosts the URL. In response, the external device (502) may receive an application store URL that is specific to the medicament type and/or the location of the external device. The external device may send a request to the application store URL to download software that is specific to the inhaler (100) and/or the medicament type of the inhaler. The application store URL may be specific to a country that the external device is located.
