Innovation Solution
A multi-communication path selection and security system that includes a medical device with a processor, bi-directional communication interface, and memory, which uses a wireless multi-communication path selection engine to prioritize network communication links based on configurable settings and policies, allowing for geographical tracking and secure communication path selection using regulated and unregulated wireless technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If software-based registration tracking is used, then the medical device can be tracked by approximate location, but the tracking is imprecise and the device can be removed and used unauthorized at any geographic location
Solution Approach 1:
The system changes the parameter of location tracking from approximate software-based registration to precise GPS coordinates. The medical device continuously monitors its geographic location using GPS technology, enabling precise determination of whether the device is within authorized geographic boundaries, thereby resolving the contradiction between tracking precision and security control.
2Reliability
If wireless technology selection is limited, then the medical device can operate with simpler communication protocols, but the device cannot ensure continuous functionality when network connectivity degrades or becomes unavailable
Solution Approach 1:
The medical device incorporates multiple wireless communication technologies (Wi-Fi, Bluetooth, cellular) to provide universal communication capability. The device can automatically switch between different wireless technologies based on availability and connectivity quality, ensuring continuous functionality across diverse network environments without requiring complex manual configuration.
Solution Approach 2:
The wireless communication system dynamically adapts to changing network conditions by automatically selecting and switching between different communication technologies. The device continuously monitors connectivity status and adjusts its communication path in real-time, transitioning from static single-technology reliance to dynamic multi-technology adaptation, thereby ensuring continuous operation.
3Reliability
If geographic tracking and security measures are implemented, then unauthorized access can be prevented, but the device requires more complex communication interfaces and protocols
Solution Approach 1:
The medical device performs self-service by automatically monitoring its own geographic location using integrated GPS and continuously assessing network connectivity status. The device autonomously determines whether it is within authorized boundaries and automatically switches communication paths based on connectivity conditions, eliminating the need for complex external monitoring systems and reducing overall system complexity.
Solution Approach 2:
The patent merges multiple functions into a single integrated system: geographic location monitoring, security boundary enforcement, and wireless communication management are combined into one unified architecture. The processor simultaneously handles GPS data, security policy evaluation, and communication path selection, reducing the need for separate complex subsystems and simplifying the overall communication interface.

AI summary
A multi-communication path selection and security system for a medical device includes a medical device and a computer. The medical device includes a processor, one or more communication interfaces, and a memory that stores configurable settings, medical device policies and profiles associated with a plurality of communication links. The processor establishes a location variable associated with the medical device and when the location variable exceeds a location proximity threshold, the processor alters one or more settings of the medical device based on the medical device policies. The processor establishes a source location variable associated with the computer or an incoming message from the computer, and when the source location variable exceeds a source proximity threshold, the processor alters the incoming message or the settings of the medical device based on the medical device policies.
