Wireless Pen Injector Medicament Verification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of drug delivery devices, such as pen injectors, often face challenges in accurately administering the correct type of medicament, leading to potential fatal mix-ups between different types of insulin or medications.
Innovation Solution
A system comprising a pen injection device, a mobile communication unit, and a software application program that determines the recommended type of medicament based on user physiological conditions and compares it with the specific type of medicament in the device, controlling the device's indication means to prevent incorrect use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If injection pens are designed with similar handling patterns and only distinguished by color or labels, then ease of manufacture and device simplicity are improved, but the risk of users accidentally using the wrong type of insulin increases
Solution Approach 1:
The system establishes a feedback loop where the injection pen communicates with the mobile device via wireless communication. The mobile device receives information about the insulin type in the pen and provides feedback by displaying guidance information or warnings to the user, ensuring the correct insulin type is used before administration
Solution Approach 2:
A mobile communication unit serves as an intermediary between the injection pen and the user. This intermediary device receives data from the pen, processes it through a software application, and provides additional layers of verification and guidance, preventing users from accidentally administering the wrong insulin type
2Reliability
If dose guidance software provides recommendations based on physiological conditions, then treatment optimization is improved, but the complexity of the system increases
Solution Approach 1:
The system merges multiple functions into an integrated solution: the injection pen contains identification technology, the mobile device provides communication and processing capabilities, and the software application delivers dose guidance recommendations based on physiological conditions, creating a unified system that improves treatment accuracy without requiring each component to be overly complex
3Reliability
If the system implements wireless communication between pen and mobile device, then medication error prevention is improved, but device complexity and energy consumption increase
Solution Approach 1:
The injection pen automatically performs identification and communication functions without requiring manual user input. The pen's identification technology and wireless communication capabilities enable the system to self-verify the insulin type and communicate with the mobile device autonomously, reducing the need for complex user interfaces while maintaining high reliability

AI summary
The present invention provides a system (1) comprising: a pen injection device (10) holding a specific type of medicament and comprising a dose expelling mechanism and pen communication means (15), a mobile communication unit (30) comprising mobile communication means (35) adapted to communicate with the pen communication means (15), and a software application program configured to determine a recommended type of medicament to be delivered to a user based on information indicative of a physiological condition of the user, wherein the pen injection device (10) further comprises indication means which in a first state indicates that the dose expelling mechanism is to remain idle and in a second state indicates that the dose expelling mechanism is available for operation, and wherein the mobile communication unit (30) is configured to, via a communication from the mobile communication means (35) to the pen communication means (15), a) prompt a change of state of the indication means from the second state to the first state in response to the recommended type of medicament to be delivered differing from the specific type of medicament, and/or b) prompt a change of state of the indication means from the first state to the second state in response to the recommended type of medicament to be delivered corresponding to the specific type of medicament.
