Wireless Infusion Pump Remote Control for Safer Bolus Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable and wearable infusion pump devices are cumbersome, require frequent user interaction, and lack remote control capabilities, posing challenges in size, weight, cost, and safety, especially for patients who need continuous medication delivery like those with diabetes.
Innovation Solution
A wireless infusion pump system comprising an infusion pump and a companion device with a user interface that allows for remote control, customizable settings, alarm settings, and visual indications of medication delivery, enabling users to manage insulin delivery without direct interaction and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable and wearable infusion pump devices are designed, then patient mobility and convenience are improved, but device size, weight, and cost increase
Solution Approach 1:
The system is divided into two separate components: a lightweight wearable infusion pump and a remote control device. The pump contains only essential components (reservoir, pump mechanism, and minimal electronics), while the remote control houses the user interface, display, and control electronics. This segmentation allows the wearable pump to be lightweight and comfortable while maintaining full functionality through wireless communication with the remote control.
2Ease of operation
If remote control capability is added to infusion pump, then user interaction frequency is reduced, but device complexity increases
Solution Approach 1:
A wireless communication system serves as an intermediary between the infusion pump and the user. The remote control device acts as a mediator that receives user inputs, processes them, and transmits control signals to the pump via wireless communication (Bluetooth, Wi-Fi, or other protocols). This intermediary approach allows users to control the pump from a distance without adding complex wiring or direct connection requirements to the pump itself.
3Reliability
If safety features are enhanced in infusion pump, then user safety is improved, but device complexity and cost increase
Solution Approach 1:
The system incorporates multiple feedback mechanisms including real-time monitoring of infusion rate, reservoir level detection, occlusion sensing, and wireless communication of status information to the remote control. The remote control provides visual and audible feedback to users about pump operation, alerts for abnormal conditions, and confirmation of delivered doses. This feedback loop enhances safety by enabling continuous monitoring and immediate user awareness of pump status without requiring complex additional hardware at the pump site.

AI summary
An infusion pump system is disclosed. The system includes at least one infusion pump, a companion device, the companion device in wireless communication with the infusion pump, and a user interfere on the companion device, the user in-terface adapted to receive textual input. A medical remote controller device is also disclosed. The device includes a display and at least one input switch dedicated to bolus delivery wherein a bolus delivery is programmed when the input switch receives an input and wherein the number of inputs by the input switch determines the amount of bolus to be delivered.
