Biometric Authentication for Medical Instrument Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical instruments require external storage media for configuration and operation mode release, lacking a simple and reliable user activation method without such media.
Innovation Solution
A process and device that activate medical instruments by detecting biometric features of users using sensors, comparing them with pre-stored data, and releasing the instrument only upon agreement, employing sensors for fingerprint, iris, or speech recognition, integrated with a central control and evaluation unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external storage media are used for user authentication, then the authentication process can be implemented, but the process becomes more complex and less reliable
Solution Approach 1:
The patent extracts the authentication data from external storage media and stores it directly in the memory of the medical instrument. The biometric sensor and processing unit are integrated into the instrument itself, eliminating the need for separate external authentication devices or media. This integration simplifies the overall system while maintaining reliable authentication through built-in biometric capabilities.
2Ease of operation
If biometric sensor means are integrated into the medical instrument, then user authentication can be performed without external media, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into the medical instrument: the biometric sensor means, the processing unit for comparing biometric data, and the memory for storing authentication data are all integrated into the instrument itself. This merging eliminates the need for separate external authentication devices, making the instrument more self-contained and easier to operate while the internal integration manages the complexity within the device architecture.
3Reliability
If biometric data is stored in the memory of the medical instrument, then authentication can be performed without external media, but the risk of data loss or unauthorized access increases
Solution Approach 1:
The patent introduces a processing unit that acts as an intermediary between the biometric sensor and the authentication decision-making process. This processing unit securely handles the comparison of detected biometric data with stored reference data in memory, ensuring that raw biometric data and reference patterns are protected during processing. The intermediary processing layer adds security protocols and controlled access mechanisms that mitigate data security risks while enabling reliable authentication.

Implementation Method 1
A sensor means, for detecting biometric features of a user, which is connected to or communicates with the medical instrument
Data Source
AI summary
A simple and reliable process for activating a medical instrument, for example, one containing an anesthetic agent- or drug-dispensing unit (23) as well as a respirator drive (24) for respirating a patient is provided. The medical instrument is switched on, and a sensor (20) for detecting biometric features of a user, which is connected to or communicates with the medical instrument, is activated by the switching on, so that the individual biometric features of a certain user are detected. Te detected individual biometric features of the certain user are compared with the biometric features of at least one user within a preset time period. The medical instrument is released for the operation by the certain user only in case of agreement between the detected individual biometric features of the certain user and biometric features of at least one user, which were entered in the memory in advance.
