Medical Fluid Delivery Device Programming Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical fluid delivery devices face challenges in ensuring accurate and safe dosing of therapeutic agents over time, as existing systems lack robust mechanisms for evaluating proposed therapy programs against reference dosages within defined analysis windows, potentially leading to excessive or insufficient drug delivery.
Innovation Solution
A processor-based system evaluates proposed therapy dosing programs by determining total dosages within overlapping analysis windows and comparing them to reference dosages, providing an indicator for clinicians to adjust programs and prevent undesirable dosing, ensuring therapy delivery aligns with safe and effective treatment parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a therapy dosing program is programmed into the medical fluid delivery device without evaluation, then the device can deliver therapy according to the program, but the total dosage delivered may be excessive or insufficient, compromising patient safety and therapeutic efficacy
Solution Approach 1:
The system performs preliminary evaluation of the therapy dosing program by calculating total dosages across multiple overlapping analysis windows before the program is executed. This advance verification identifies potential dosing errors and prevents unsafe therapy delivery, resolving the contradiction by ensuring patient safety through pre-programming validation without requiring complex real-time monitoring systems.
Solution Approach 2:
The system provides feedback to the clinician or user regarding the total dosage calculations for different analysis windows, indicating whether the proposed therapy program delivers acceptable dosages. This feedback mechanism allows the user to adjust the program before implementation, ensuring safety while maintaining relatively simple device architecture.
2Measurement precision
If the system evaluates therapy programs using multiple overlapping analysis windows, then the accuracy of dosage assessment is improved, but the computational complexity and time required for program evaluation increases
Solution Approach 1:
The evaluation process divides the therapy program into multiple overlapping analysis windows of different durations (e.g., 24-hour, 48-hour, 72-hour windows). Each window independently assesses total dosage for its specific time period, providing comprehensive and accurate dosage evaluation without requiring complex continuous analysis of the entire therapy duration, thus balancing precision with computational efficiency.

AI summary
In some aspects, systems, devices, and techniques for programming a medical fluid delivery device are described. In one example, the disclosure relates to a system including a medical fluid delivery device configured to deliver a therapeutic agent to a patient, and a processor. The processor may be configured to receive a proposed therapy dosing program that defines a fluid therapy for delivery to a patient via a medical fluid delivery device for a first period of time, determine a total dosage over a second period of time, where the second period of time at least partially overlaps the first period of time, and compare the total dosage over the second period of time to a reference dosage.
