Medicament Dosage Data Collection via Optical Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicament delivery devices lack reliable methods for accurately recording and confirming medicament dosages, particularly in scenarios where user confirmation is absent, leading to potential incorrect administration of doses.
Innovation Solution
A data collection device equipped with a camera and display that captures images of the medicament dose indicator, determines if an injection has been administered without prior user confirmation, and prompts the user to set the medicament dosage amount, allowing for accurate logging and storage of injection data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical sensors are used to detect dosage information, then measurement capability is improved, but reliability of dosage recording deteriorates when user confirmation is absent
Solution Approach 1:
The system captures images of the dosage indicator, processes them to determine the programmed dosage amount, and provides feedback to the user by displaying the detected dosage. This feedback loop allows verification of the detected dosage and enables correction if the detected value is incorrect, thereby improving reliability while maintaining measurement capability
Solution Approach 2:
The patent introduces an intermediary processing step between optical detection and final dosage recording. The system uses image capture and processing as an intermediary to verify the dosage indicator, and requires user confirmation as another intermediary layer before finalizing the dosage record, thus improving reliability without sacrificing measurement precision
2Ease of operation
If manual dosage selection is allowed, then ease of operation is improved, but risk of incorrect dosage administration increases
Solution Approach 1:
The system provides automatic feedback by capturing an image of the dosage indicator, processing it to determine the programmed dosage amount, and displaying this information to the user. This feedback mechanism allows the user to verify the dosage before administration, maintaining ease of operation while reducing the risk of incorrect dosage through automatic verification
Solution Approach 2:
The patent implements preliminary anti-action by detecting the programmed dosage amount before injection occurs and providing this information to the user for confirmation. This preliminary verification step prevents incorrect dosage administration by alerting the user to the actual programmed dosage before the harmful action of injection takes place

Data Source
AI summary
A data collection device is configured to capture images of a dosage indicator of a medicament delivery device and, if an injection is administered without prior confirmation of a dosage amount, to prompt the user to set a value for the delivered medicament dosage amount for storing in a dosage log. For example, the determination may be based on specific confirmation from the user or detecting a zero dosage amount in captured images. A suggested dosage amount may be displayed to the user, for example a highest or more recently programmed dosage amount prior to the injection or based on one or more previously confirmed dosage amounts. The data collection device may use one or more of optical character recognition, optical pattern recognition and determination of direction of rotation of a dosage adjustment component to determine whether an injection is being, or has been, administered and/or a suggested dosage amount.
