Infusion Pump RF Tag Selection Logic for Drug Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical infusion pumps face challenges in accurately administering drugs when multiple RF tags with different identification information are read, leading to confusion about which information to use for setting drug administration parameters.
Innovation Solution
A medical infusion pump system that includes a reader capable of reading RF tags and a control unit that selects only one piece of identification information when two or more are read, using data from a predetermined region to distinguish between standard and unique codes, and communicates with a server to acquire prescription information for accurate drug administration settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple RF tags are attached to a syringe container for both logistics management and drug authentication, then the ability to identify and authenticate the drug is improved, but the complexity of selecting which identification information to use for drug administration settings increases
Solution Approach 1:
The patent segments the identification information from multiple RF tags by analyzing predetermined regions of each tag's data. The control unit divides the identification information into segments based on data structure characteristics (e.g., standard codes vs. unique institution codes) and selectively processes only the relevant segment for drug administration settings, thereby resolving the contradiction between having multiple tags for reliability and the complexity of selecting among them.
2Loss of information
If the medical infusion pump reads all RF tags on a syringe container, then complete drug identification information is obtained, but the time required to process and select the correct identification information increases
Solution Approach 1:
The patent applies preliminary action by pre-defining specific regions or data structures within the RF tag information that are most likely to contain the correct drug identification data. The control unit is programmed with predetermined criteria (such as expected data formats, length, or structure) that allow it to quickly identify and select the relevant identification information without exhaustively processing all possible tags, thus reducing processing time while maintaining information completeness.
3Measurement precision
If the control unit selects identification information from multiple RF tags, then the accuracy of drug administration settings can be improved, but the risk of selecting incorrect information and causing administration errors increases
Solution Approach 1:
The patent implements feedback mechanisms where the control unit validates the selected identification information against multiple criteria before using it for drug administration settings. The system checks whether the selected information matches the expected data structure, cross-references it with the drug library, and verifies consistency across multiple tags. This feedback loop ensures high measurement precision while minimizing the risk of selecting incorrect information, as erroneous selections are detected and rejected through the validation process.

Function Achieved in This Case
Ensures accurate and safe drug administration by selecting the appropriate identification information and setting drug administration parameters based on prescription information, reducing the risk of errors due to multiple or mismatched RF tags.
Implementation Method 1
a reader that reads identification information stored in an RF tag by wireless communication
Data Source
AI summary
A medical infusion pump includes: a reader configured to read identification information stored in an RF tag by wireless communication; and a control unit configured to set information about administration of a drug based on the identification information read from the RF tag. In a case in which the reader reads two different pieces of the identification information, the control unit selects only one piece of the identification information out of the two different pieces of the identification information and sets the information about administration based on said one piece of the identification information.
