Biometric User Pairing for Accurate Medicament Delivery Event Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicament delivery devices face challenges in accurately identifying and registering medicament delivery events due to the presence of multiple injectors, with existing technologies failing to ensure that the identified medicament delivery belongs to the designated user associated with the receiver, and an erroneous registration of a medical event may be performed by the receiver.
Innovation Solution
The method involves preregistering a medicament delivery device with biometric information of the user during a preregistration phase, using a biometric sensor to verify the user's identity, and ensuring that only registered devices and communication devices are recognized as valid for event registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless communication is used to transmit medicament delivery events, then communication speed and convenience are improved, but reliability deteriorates due to inability to verify user-device association
Solution Approach 1:
The system performs preliminary biometric verification and user-device association registration before actual medicament delivery events occur. The receiver stores the association between biometric data and device identifiers in advance, so that when a delivery event occurs, the system can quickly verify the association without delaying the communication process. This resolves the contradiction by preparing verification data beforehand, maintaining both speed and reliability.
2Reliability
If biometric verification is added to verify user identity, then reliability of user identification is improved, but device complexity increases
Solution Approach 1:
The patent introduces a receiver as an intermediary device that handles biometric verification and user-device association management. Instead of embedding complex biometric sensors and verification logic in the medicament delivery device itself, the receiver acts as a separate entity that receives wireless signals from the device, verifies user identity through biometric data, and manages the association database. This externalizes the complexity to a dedicated verification system, maintaining reliability while allowing the delivery device to remain relatively simple.

AI summary
A method of a receiver of associating a user with a medicament delivery device configured to communicate a medicament delivery event wirelessly with the receiver is provided. The method comprises receiving, during a preregistration phase, a first wireless signal comprising information identifying at least one medicament delivery device and biometric information identifying a user of said at least one medicament delivery device, receiving a second wireless signal identifying a medicament delivery device communicating a medicament delivery event, determining whether or not the second wireless signal comprises a device identifier received during the preregistration phase, and if so determining that the medicament delivery device identified with the received second wireless signal was used by the user identified with the biometric information for causing the medicament delivery event.
