Dynamic Patient Gateway Pairing for Reliable Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient monitoring systems face challenges with data transmission from wearable devices to remote monitoring centers, including slow communication due to multiple devices sharing a single gateway, lack of flexibility in pairing schemes, and high costs, which can lead to delayed or unreliable transmission of critical patient data.
Innovation Solution
A system comprising a server, gateway, and patient devices where the gateway communicates only with approved devices listed by the server, using unique identifiers for pairing and encryption, allowing for controlled and reliable data transmission from multiple patient devices to a backend server, even in large-scale setups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple patient devices share a single gateway for data transmission, then device complexity is reduced, but communication speed and reliability deteriorate
Solution Approach 1:
The patent divides the single gateway into multiple gateways, each handling a subset of patient devices. This segmentation allows parallel data transmission paths, increasing overall communication speed and reliability while maintaining manageable complexity at each individual gateway node.
Solution Approach 2:
The patent introduces a hierarchical dimension to the network architecture, with patient devices connecting to multiple potential gateways and gateways connected to multiple devices. This multi-dimensional connectivity provides redundant transmission paths, improving speed and reliability without requiring each device to maintain complex direct connections to all other devices.
2Ease of operation
If open pairing schemes are used for device connectivity, then ease of operation is improved, but system reliability and security worsen
Solution Approach 1:
The patent implements dynamic pairing where the set of approved devices for each gateway is not fixed but can be updated and modified. The server maintains an approved devices list that can be dynamically adjusted, allowing flexible enrollment and removal of devices while ensuring only authorized devices can connect to specific gateways, thus maintaining both ease of operation and reliability.
Solution Approach 2:
The system incorporates feedback mechanisms where the server monitors and manages device-gateway pairings, maintaining an approved devices list that provides continuous verification. This feedback loop ensures that only authorized devices can establish connections, maintaining security and reliability while allowing operational flexibility through server-managed approval processes.
3Reliability
If centralized server control is implemented for device approval, then system reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary that manages the approved devices list and coordinates device-gateway pairings. This centralizes the complexity of pairing management at the server level rather than requiring complex logic in each device or gateway, simplifying the edge devices while maintaining reliable communication integrity through server-mediated approval and monitoring.

AI summary
Systems, devices and methods transmit data from a patient device to a location, for example a remote location, where the patient is monitored. The system may comprise a server system, for example a backend server system, a gateway and the patient worn device. The gateway can be configured to communicate with the patient worn device in response to a list transmitted from the server, for example an approved patient device list transmitted from the server to the gateway. The gateway may exclude communication with patient worn devices that are not on the list. This use of the list can control data throughput from the patient device to the gateway and also from the gateway to the server, such that the communication from the device on the list to the server is maintained and appropriate information can be reliably sent from the patient device to the server.
