Infusion Pump Unit Comparison to Prevent Titration Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infusion pumps often experience titration errors due to unqueried changes in units of measure for infusion regimens, which can lead to medication delivery errors, especially in primary/secondary configurations where gravitational head pressure differences affect flow rates and volumes.
Innovation Solution
An infusion pump with a graphical user interface and processor that compares units of measure for different infusion regimens, generates warning messages for discrepancies, and holds initiation of regimens in abeyance until confirmation or proper adjustment is made, ensuring that units of measure remain consistent and accurate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pump allows unqueried changes in units of measure for infusion regimens, then the ease of operation is improved, but the reliability deteriorates due to titration errors
Solution Approach 1:
The system provides feedback to the user when a unit of measure change is detected between first and second infusion regimens. The processor generates a warning message that is displayed on the graphical user interface, alerting the user to the potential titration error caused by the unit change, thereby preventing erroneous medication delivery
Solution Approach 2:
The system performs preliminary detection and warning before the second infusion regimen is fully initiated. By comparing units of measure and issuing warnings in advance, the system prevents titration errors from occurring rather than detecting them after the fact
2Productivity
If the pump initiates the second infusion regimen without verification, then the productivity is improved, but the manufacturing precision deteriorates due to incorrect volume delivery
Solution Approach 1:
The system monitors and compares units of measure for different infusion regimens, providing feedback when discrepancies are detected. This ensures accurate volume delivery by alerting users to unit changes that could affect medication dosing precision
Solution Approach 2:
The system replaces manual verification of unit consistency with an automated processor that electronically compares units of measure between regimens, generating warnings when changes are detected, thereby ensuring precision without manual intervention
3Ease of operation
If the pump does not query volume changes for secondary medications with greater gravitational head pressure, then the ease of operation is improved, but the reliability deteriorates due to unverified volume entries
Solution Approach 1:
The system provides specific feedback when volume changes are detected for secondary medications. The processor generates warning messages that highlight the volume parameter in unit of measure changes, ensuring users verify the correctness of volume entries for medications with greater gravitational head pressure
Data Source
AI summary
An infusion pump including an interface unit for receiving first data for a first infusion regimen for a medication, the first regimen including a first unit of measure in which the first regimen is executed and after receipt of the first data, second data for a second infusion regimen for the medication, the second regimen including a second unit of measure in which the second regimen is executed. The pump also includes a processor for comparing the first and second units of measure. In one embodiment, the pump includes a graphical user interface, and the processor identifies a difference between the first and second units of measure; generates, using the processor, a warning message; and displays the message on the graphical user interface. In another embodiment, the processor holds in abeyance initiation of the second infusion regimen in response to identifying the difference between the units of measure.
