Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the capability for safe and efficient self-administration of pharmaceutical and non-pharmaceutical medications via subcutaneous, intravenous, or inhalation methods outside clinical settings, due to concerns over safety and compliance, limiting access to therapies for patients.
Innovation Solution
A fluid pumping system with a fluid pump device, automatic cannula inserter, and user interface that allows for precise and safe delivery of medications, featuring a drive motor, reflective object sensor, and adhesive cover for secure skin attachment, enabling patients to administer therapies at home with guided steps and remote monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patients self-administer therapies at home, then patient access and satisfaction improve, but safety and compliance concerns arise
Solution Approach 1:
The system enables patients to self-administer therapies through an automated pump device that performs the actual drug delivery without requiring clinical personnel. The device includes automated cannula insertion, precise dosing control, and monitoring functions that allow patients to independently manage their therapy at home, directly addressing the self-service aspect of the contradiction.
Solution Approach 2:
The system incorporates multiple monitoring and feedback mechanisms including reflective object sensors to detect skin contact, flow sensors to monitor drug delivery, and user interface displays that provide real-time feedback on therapy status. This continuous feedback loop ensures safe operation and maintains compliance by alerting patients and caregivers to any deviations from the prescribed therapy protocol.
2Ease of operation
If automated cannula inserter is used, then ease of operation improves, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-assembling the cannula and inserter mechanism in a sterile, pre-sterilized configuration within the pump device. The automatic inserter is pre-loaded with the cannula assembly, and the device is pre-programmed with insertion parameters. This preliminary preparation simplifies the actual insertion operation to a single automated action while managing the complexity through advance configuration.
Solution Approach 2:
The system merges multiple functions into the automatic inserter assembly, combining the cannula, inserter needle, and positioning mechanisms into a single integrated unit. This consolidation reduces the number of separate components and procedures needed, making the operation simpler despite the inherent complexity of the automated mechanism.
3Measurement precision
If reflective object sensor is used to detect skin contact, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical sensing mechanisms with optical reflective object sensors that detect skin contact through light reflection. This substitution provides precise detection capability while maintaining relatively simple device architecture, as optical sensors are more compact and easier to integrate than mechanical pressure or capacitive sensing systems.
