Infusion Pump Device Pairing via Primary Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing medical pump systems require time-consuming and error-prone pairing processes between devices, such as smartphones and infusion pumps, due to the need for manual entry of complex security codes, which complicates the connection of multiple devices and can lead to inefficiencies in secure communication.
Innovation Solution
Implementing a method where a primary device securely pairs with an infusion pump and shares the secure connection information with secondary devices, allowing them to automatically pair without re-executing the initial pairing procedure, and using camera-based scanning to eliminate manual entry of security codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry of complex security codes is used for device pairing, then security is improved, but pairing time and operational complexity increase
Solution Approach 1:
The system performs preliminary pairing actions by having the primary device pre-share secure connection information with secondary devices before they need to connect to the pump. This preliminary exchange of pairing credentials eliminates the need for repeated manual security code entry during subsequent pairing operations.
Solution Approach 2:
The primary device acts as an intermediary that facilitates secure connection between secondary devices and the infusion pump. Instead of each device independently entering security codes with the pump, the primary device mediates by sharing its established secure connection information with secondary devices, enabling them to pair securely without direct manual code entry.
2Reliability
If manual entry of complex security codes is required for each device, then security is maintained, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service pairing where secondary devices automatically obtain secure connection information from the primary device without requiring manual user intervention for code entry. The devices serve themselves by automatically exchanging and applying pairing credentials, eliminating the need for users to manually type complex security codes.
Solution Approach 2:
The primary device serves as an intermediary that automatically provides secure connection information to secondary devices. This mediation eliminates the need for users to manually enter security codes on each device, as the primary device handles the distribution of pairing credentials automatically.
3Ease of operation
If secure connection information is shared with multiple devices, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system segments the pairing management function by designating a primary device to handle secure connection information distribution. This segmentation allows the primary device to manage multiple secondary devices independently, where each secondary device receives and stores its own specific pairing credentials from the primary device, simplifying the overall multi-device pairing architecture.
4Reliability
If repeated pairing procedures are executed for each device, then security is maintained, but productivity deteriorates
Solution Approach 1:
The system performs the security credential exchange in advance through the primary device, so that secondary devices already possess valid secure connection information before they need to connect to the infusion pump. This preliminary action eliminates the need to repeat the full pairing procedure for each additional device.
Solution Approach 2:
The primary device copies its secure connection information and distributes it to secondary devices. Instead of each device independently establishing a secure connection through repeated pairing procedures, the system uses the primary device's established credentials as a template that is copied and distributed to multiple secondary devices, maintaining security while improving efficiency.
