Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion pumps are cumbersome, require frequent user interaction, and lack remote control capabilities, posing challenges in size, weight, cost, and safety, especially for patients needing continuous parenteral drug delivery like insulin.
Innovation Solution
A wireless infusion pump system comprising an infusion pump and a companion device with a user interface for textual input, enabling remote control, customizable settings, and safety features like alarm settings and visual indications for bolus delivery, allowing for reduced user interaction and enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infusion pumps are made portable and wearable with electronic control, then drug delivery convenience is improved, but device size, weight and cost increase
Solution Approach 1:
The system divides the infusion pump functionality into two separate components: a portable wearable pump unit for drug delivery and a remote controller for operation and control. This segmentation allows the pump to remain lightweight and simple while the controller handles complex functions, resolving the contradiction between portability and functionality.
Solution Approach 2:
A wireless communication intermediary (radio frequency transceiver) is introduced between the pump and the remote controller, enabling the pump to be controlled remotely without requiring direct user interaction or increasing its own complexity. This allows the pump to remain simple and lightweight while still providing convenient drug delivery through remote control.
2Measurement precision
If infusion pumps require frequent direct user interaction, then control precision is improved, but user burden and safety risks increase
Solution Approach 1:
The system implements multiple feedback mechanisms including occlusion detection sensors that monitor fluid flow and alarm systems that notify users of abnormal conditions. This automated feedback maintains control precision while reducing the need for frequent manual user interaction, thereby improving safety by reducing user burden and potential for human error.
Solution Approach 2:
The infusion pump performs self-monitoring functions through integrated sensors that detect occlusions and track drug delivery status automatically. This self-service capability maintains precise control of the infusion process without requiring constant user attention, reducing safety risks associated with frequent manual intervention.
3Volume of moving object
If infusion pump size is reduced for portability, then wearable capability is improved, but device functionality and safety features are reduced
Solution Approach 1:
The remote controller acts as an intermediary that provides expanded functionality and safety features without being integrated into the pump itself. This allows the pump to remain small and portable while the controller offers comprehensive control options, programming capabilities, and safety monitoring, effectively resolving the contradiction between size and functionality.
