Insulin Pump Parameter Configuration with Authorization Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insulin pump configurations lack a secure and efficient method for authorized access and modification of parameters, leading to potential unauthorized changes and inefficiencies in user-specific settings.
Innovation Solution
A computer-implemented method and device for configuring an insulin pump using parameter blocks with restriction settings, where the pump configuring device compares its authorization level to the restriction settings to determine and enforce access rights, allowing authorized changes while preventing unauthorized modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If insulin pump parameters are made accessible for configuration, then ease of operation is improved, but reliability deteriorates due to potential unauthorized changes
Solution Approach 1:
The patent segments parameters into different categories (editable and non-editable) based on their modification requirements. The processor selectively enables editing access to specific parameter categories based on the authorization level of the configuring device, allowing routine parameters to be easily modified while protecting critical parameters from unauthorized changes.
Solution Approach 2:
Different authorization levels are assigned to different parameter blocks within the system. Critical parameters have higher authorization requirements while less critical parameters allow broader access. The system applies different security policies locally to different parameter groups, optimizing both accessibility and security.
2Reliability
If authorization levels are implemented for parameter access, then reliability is improved, but device complexity worsens
Solution Approach 1:
Authorization levels and restriction settings are pre-configured in the system before parameter modification attempts. The insulin pump and configuring devices are pre-programmed with authorization credentials, allowing the processor to automatically determine access rights without requiring complex runtime authentication protocols.
Solution Approach 2:
The patent uses backup parameter blocks that store authorized parameter values. When authorization is granted, the processor can copy validated parameter values from backup blocks to active parameter blocks, ensuring integrity while simplifying the modification process.
3Adaptability or versatility
If all parameters are editable, then adaptability is improved, but harmful factors worsen due to inadvertent changes
Solution Approach 1:
The system applies preliminary anti-action by blocking access to non-editable parameters before modification attempts can occur. The processor checks authorization levels and restriction settings beforehand, preventing access to critical parameters that could cause harmful effects if modified incorrectly.
Solution Approach 2:
The system dynamically adjusts parameter editability based on the authorization level of the configuring device. Parameters that are locked for low-authorization devices may become editable for high-authorization devices, allowing the system to balance adaptability and safety based on the current operational context.

AI summary
An insulin pump is configurable by a configurator. The pump has parameter blocks, each with a respective parameter and an associated restriction setting, and the configurator has an authorization level. Configuring the pump includes receiving, by the configurator, a request to access a parameter on the pump. The method also includes identifying, by the configurator, the parameter block that includes the parameter. Moreover, the method includes retrieving, by the configurator from the pump, the parameter and the associated restriction setting, and comparing, by the configurator, the authorization level of the configurator to the restriction setting. Also, the method includes determining, by the configurator, whether the configurator is authorized to write to the parameter block based on the comparison. Additionally, the method includes writing, by the configurator, to the parameter block on the insulin pump in response to a determination that the configurator is authorized to write to the parameter block.
