Computerized Blood Transfusion System with Barcode Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual and automated systems for blood transfusion are flawed, leading to potential transfusions of incompatible blood due to misidentification of patients and blood products, lack of real-time inventory and testing results, and inadequate documentation of vital signs and transfusion processes, resulting in safety risks and inefficiencies.
Innovation Solution
A computerized system that identifies both the blood product and patient, accesses a database for compatibility testing results, and ensures compatibility before transfusion, while documenting vital signs and updating the blood bank database in real-time, integrating processes across departments for accurate and safe blood administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual identification checks are used to verify patient and blood product compatibility, then personnel can directly compare identifiers, but human errors such as misidentification and failure to follow procedures occur leading to incompatible transfusions
Solution Approach 1:
The patent replaces manual mechanical identification processes with an automated computerized system that uses bar code scanners and database queries to verify patient-blood product compatibility, eliminating human error in the comparison process while maintaining operational efficiency
Solution Approach 2:
The system enables self-verification through automated bar code scanning and real-time database validation, where the computerized system automatically checks compatibility without requiring personnel to manually compare identifiers, thus improving reliability while reducing operational complexity
2Loss of information
If secondary labeling systems are used to identify patients and track blood products, then additional identification layers are provided, but system complexity increases and real-time access to inventory and testing results is not achieved
Solution Approach 1:
The patent implements a universal bar code labeling system that serves multiple functions simultaneously: patient identification, blood product tracking, compatibility verification, and real-time database updates, replacing multiple separate identification systems with a single integrated solution
Solution Approach 2:
The bar code label acts as an intermediary carrier that consolidates all critical identification and tracking information in a machine-readable format, enabling seamless data exchange between the blood bank department and clinical areas without requiring complex manual tracking systems
3Measurement precision
If manual documentation of vital signs and transfusion processes is performed, then personnel can record observations, but time consumption increases and accuracy decreases leading to incomplete or erroneous records
Solution Approach 1:
The patent replaces manual documentation processes with automated electronic data capture through bar code scanning and computerized system interfaces, eliminating manual entry errors and reducing documentation time while improving accuracy of vital signs and transfusion process records
4Reliability
If blood compatibility testing is performed in the blood bank department, then compatibility results are obtained, but real-time access to these results at the point of care is not provided leading to potential transfusion of incompatible blood
Solution Approach 1:
The patent implements a real-time feedback system where bar code scanning at the point of care automatically queries the central database for compatibility results, providing immediate verification or alerting personnel to incompatibility, thus ensuring reliable verification without time delay
Solution Approach 2:
The computerized network system acts as an intermediary that bridges the blood bank department and clinical areas, enabling real-time data exchange and immediate access to compatibility testing results through the integrated database, eliminating information access delays

AI summary
The present invention relates to a system and method for safely transfusing blood to a patient in a computerized healthcare environment is provided. A blood product to be administered to a patient is identified and the patient is identified. A database containing a plurality of blood compatibility test results is accessed and it is determined whether the database contains a blood compatibility test result for the identified blood product and identified patient. If so, it is determined whether the test result indicates that the identified blood product is compatible for the identified patient.
