Solution Overview
Problem
Existing infusion devices lack user-friendly interfaces and fail to provide precise dosage control and access to pertinent patient information.
Innovation Solution
The development of graphic user interfaces (GUIs) for intravenous infusion devices, featuring touch-screen displays that allow medical professionals to input commands, adjust medication dosages, and review patient vital signs and medication delivery settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If volumetric pumps are used to provide precise dosage rates, then dosage precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system divides the infusion pump functionality into separate modules: a microprocessor unit for precise dosage control, a display unit for user interaction, and a pump mechanism for fluid delivery. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining precision.
Solution Approach 2:
A microprocessor acts as an intermediary between the user interface and the pump mechanism, translating user commands into precise dosage rates. This intermediary layer simplifies the user interface while maintaining accurate dosage control, resolving the contradiction between precision and ease of operation.
2Adaptability or versatility
If volumetric pumps with multiple medication capabilities are used, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The infusion pump is designed with universal functionality to handle multiple medications and infusion types through a single integrated device. The microprocessor-controlled system can be programmed for different dosage rates, medication types, and patient parameters, providing versatility without requiring multiple separate devices.
Solution Approach 2:
The system allows pre-programming of dosage parameters, patient information, and infusion settings before actual medication administration. This preliminary configuration simplifies operation during patient care, as the pump automatically manages complex dosage calculations and adjustments based on pre-set parameters.
3Device complexity
If traditional infusion devices are used, then device complexity is reduced, but information access and user interface quality deteriorate
Solution Approach 1:
The system replaces traditional mechanical controls and analog displays with a microprocessor-based control system and visual display interface. This substitution enables comprehensive patient information storage and access while maintaining relatively simple device architecture through software-based management.

AI summary
Systems and methods are described for presenting information for managing a vital sign of a patient. A graphical user interface (GUI) can be presented that displays information concerning a vital sign of a patient, including the most current value of the vital sign received and past values of the vital sign over an elapsed time period. Preferably, the systems and methods are used with a closed-loop system that may automatically adjust a dosage rate of a medication, although manual control is also contemplated. The GUI may comprise one or more visual indicators presented on the historical data that, when selected, present additional information that may be useful to managing the care of the patient.
