Integrated Fingerprint Blood Sampling Device for Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for associating medical specimen samples with patient identity are prone to human error and intentional mislabeling, lacking a foolproof method to ensure the identity of the specimen donor.
Innovation Solution
A device and method that combines a fingerprint reader with a blood sampling mechanism, allowing a user to verify their identity through fingerprint scanning while simultaneously drawing a blood sample, ensuring that the sampled blood is from the correct individual.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual labeling methods are used to associate specimen samples with patient identity, then the process is simple and quick, but the reliability of specimen-patient pairing is compromised due to human error and potential mislabeling
Solution Approach 1:
The patent combines the fingerprint reading function and blood sampling function into a single integrated device. The fingerprint reader and blood sampling mechanism are merged into one unit, allowing simultaneous identification and specimen collection. This resolves the contradiction by integrating multiple functions into a single device, improving reliability without proportionally increasing complexity.
Solution Approach 2:
The patent introduces a fingerprint template as an intermediary element that links the patient's identity to the blood sample. The fingerprint template stored in memory serves as a mediator that verifies the patient's identity before allowing blood collection, ensuring accurate specimen-patient pairing without requiring complex manual labeling procedures.
2Reliability
If fingerprint verification is integrated with blood sampling, then the identity verification reliability is improved, but the device complexity and operational steps increase
Solution Approach 1:
The patent performs fingerprint verification before blood sampling. The system first reads and verifies the fingerprint template, confirming the patient's identity prior to the blood collection step. This preliminary action ensures identity verification is completed in advance, making the overall process more reliable while maintaining ease of operation through a clear sequential workflow.
Solution Approach 2:
The patent merges the fingerprint reading and blood sampling operations into a single integrated device and process flow. By combining these functions, the system improves identity verification reliability while minimizing the increase in operational complexity, as both actions occur within the same device interface and procedure.
3Object-affected harmful factors
If manual specimen association methods are used, then the equipment required is simple, but the potential for harmful factors such as mislabeling and unauthorized access increases
Solution Approach 1:
The patent uses a fingerprint template stored in memory as an intermediary that mediates between the patient's identity and the blood sample. This template verification mechanism prevents mislabeling by ensuring the sample is collected from the verified individual, and prevents unauthorized access by requiring successful fingerprint authentication before sampling can occur.
Solution Approach 2:
The system performs automatic fingerprint verification and sample collection without requiring manual labeling or external verification. The device itself verifies the patient's identity through fingerprint matching and automatically proceeds with blood sampling only when verification succeeds, eliminating human error and potential misuse associated with manual processes.

AI summary
Providing an ID-verified blood test, in one aspect, may include enabling a user to press a finger against a fingerprint-reading panel and reading a fingerprint of the user. A blood sampling device coupled to the fingerprint-reading panel may be activated while the user has the finger against the fingerprint-reading panel to sample blood from the finger. Blood may be sampled from the user via the blood sampling device while the user has the finger against the fingerprint-reading panel. A test may be performed on the sampled blood to determine a level of specified chemical in the blood. User identification may be determined based on the fingerprint. The determined user identification and the level of the specified chemical may be returned.
