Medical Device Location Authorization via Role Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing electronic nature of medical devices and scattered facilities complicates training, treatment, and troubleshooting, leading to inefficiencies and potential unauthorized access that can introduce errors in patient treatment.
Innovation Solution
Implementing a location and role-based authorization system that assigns permissions to users based on their functional role and location, using a data management system to interact with medical devices and restrict access to authorized locations, ensuring secure and flexible operation of medical devices like infusion pumps and apheresis systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If medical devices are made electronic and distributed across scattered facilities, then functionality and accessibility are improved, but training, treatment, and troubleshooting become difficult and unauthorized access risks increase
Solution Approach 1:
A centralized data management system acts as an intermediary between users and distributed medical devices. This system provides unified access control, device monitoring, and operational support across scattered facilities, making the system easier to manage while maintaining broad accessibility.
Solution Approach 2:
The data management system serves multiple functions simultaneously: it authenticates users, authorizes device access, monitors device status, and provides operational guidance. This multi-functional approach simplifies the overall system operation despite the distribution of devices across multiple locations.
2Adaptability or versatility
If medical devices are distributed across scattered facilities, then accessibility is improved, but unauthorized access risks increase
Solution Approach 1:
The data management system serves as a security intermediary that mediates all access requests to distributed medical devices. It verifies user credentials, checks authorization levels, and controls device access accordingly, maintaining security while enabling broad accessibility across facilities.
Solution Approach 2:
Access control is customized locally for each facility and device while being managed centrally. The system applies different authorization rules and security policies to different locations and devices, allowing each to have appropriate access restrictions while maintaining overall system security.
3Reliability
If location-based access control is implemented, then security and reliability are improved, but device complexity increases
Solution Approach 1:
The data management system acts as an intermediary that handles all the complexity of location-based authorization. Individual medical devices don't need complex authorization logic built in; instead, they communicate access requests to the centralized system, which manages the authorization complexity centrally.
Solution Approach 2:
The system merges authentication, authorization, and device control functions into a single data management system. This consolidation prevents the proliferation of complex authorization mechanisms across multiple devices while maintaining comprehensive security control.

AI summary
Systems, methods, and apparatus for medical device management are disclosed. An example tangible computer readable storage medium includes instructions that, when executed, cause a processor to at least launch a first user interface to configure a first user group based on a first role, generate a role mapping in response to configuring the first user group based on the first association, launch a second user interface to configure the first user group based on a first deployment location, generate a location mapping in response to configuring the first user group based on the second association, generate a combined location and role mapping based on the role mapping and the location mapping, and launch a third user interface to facilitate interaction of the first user account with the medical device in response to determining whether the first user account is authorized to access the medical device based on the combined mapping.
