Defibrillator Accessory Authentication for Safe Feature Enablement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unauthorized medical accessories can compromise patient care by potentially malfunctioning or not functioning properly with medical devices, making it difficult to distinguish between authorized and unauthorized accessories.
Innovation Solution
A medical device system that includes a processor to authenticate accessories by verifying a preset data set, enabling basic and advanced functionalities only when an authorized accessory is coupled, and disabling advanced functionality if authentication is not confirmed, thereby ensuring secure operation and alerting operators of potential compromised patient care.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication verification is implemented to distinguish authorized accessories, then patient care safety is improved, but device operation complexity increases
Solution Approach 1:
The system performs authentication verification of the accessory before enabling advanced functionalities. The processor checks whether the coupled accessory is authorized to work with the medical device, and only after successful authentication does it allow access to advanced features. This preliminary verification ensures patient safety while maintaining a relatively simple user interface.
Solution Approach 2:
The device functionality is segmented into basic operations that are always available and advanced functionalities that require authentication. This segmentation allows the system to provide essential functions without complexity while restricting advanced features to authorized accessories only, thus improving reliability without overwhelming the user with complexity.
2Ease of operation
If advanced functionalities are enabled without authentication, then ease of operation is improved, but reliability of patient care deteriorates
Solution Approach 1:
The system dynamically adjusts its operational state based on authentication results. When an unauthorized accessory is detected, the system automatically disables advanced functionalities while maintaining basic operations. This dynamic response ensures ease of operation for basic functions while protecting patient care reliability by preventing unauthorized accessory usage from compromising advanced features.
3Reliability
If authentication criterion is set to be strict, then reliability of accessory authorization is improved, but ease of operation worsens due to more restrictions
Solution Approach 1:
The system applies authentication restrictions selectively rather than universally. Basic medical device functions remain accessible without authentication, while only advanced functionalities require verification of authorized accessories. This partial application of authentication maintains reliability for critical functions while preserving ease of operation for essential tasks.

AI summary
Embodiments are directed to a medical device, such as a defibrillator, for use with an accessory capable of collecting a parameter of a patient. The medical device is capable of at least performing a basic functionality, an advanced functionality, and of defibrillating the patient. The medical device includes an energy storage module within a housing for storing an electrical charge that is to be delivered to the patient for the defibrillating. The medical device includes a processor structured to determine whether a data set received from the accessory confirms or not a preset authentication criterion about the accessory. Although when the accessory is coupled to the housing the medical device is capable of the defibrillating and the basic functionality, the medical device is capable of the advanced functionality only when the accessory is coupled to the housing and it is determined that the preset authentication criterion is confirmed. Embodiments also include methods of operation and a programmed solution.
