Ambulatory Infusion Pump Step Therapy GUI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ambulatory infusion pumps are complex and time-consuming to program for therapies requiring step therapy delivery profiles, such as IVIG, and often lack customization options during infusion.
Innovation Solution
An ambulatory infusion pump system with a graphical user interface (GUI) that allows users to input parameters for a step delivery function, including initial rate, plateau rate, step duration, rate increment, and total infusion volume, with a processor to calculate infusion duration and adjust parameters as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional infusion pumps use spreadsheet-based profiles for step therapy delivery, then the delivery profile can be maintained, but the setup and programming becomes complicated and time-consuming
Solution Approach 1:
The pump is pre-programmed with step therapy delivery algorithms and multiple preset profile templates (e.g., IVIG-specific profiles) that automatically calculate infusion parameters based on simple user inputs like total volume and desired duration. This preliminary configuration eliminates the need for complex spreadsheet-based programming during setup.
Solution Approach 2:
The system performs automatic calculations of infusion rates, step intervals, and profile parameters based on user-provided basic information. The pump self-configures the delivery profile without requiring manual spreadsheet manipulation, thereby reducing setup time while maintaining accuracy.
2Productivity
If conventional infusion pumps use fixed spreadsheet-based profiles, then the delivery can proceed, but customization is not possible during infusion
Solution Approach 1:
The infusion profile is designed to be dynamically adjustable during infusion. Users can modify parameters such as step duration, rate increment, and plateau rate in real-time based on patient tolerance, allowing the system to adapt while maintaining efficient delivery.
Solution Approach 2:
While providing preliminary preset profiles for immediate use, the system also prepares the infrastructure for easy modification during infusion, combining the benefits of quick start-up with flexible customization capability.
3Manufacturing precision
If conventional infusion pumps require complex programming for step therapy, then precise control can be achieved, but the operation becomes difficult and time-consuming
Solution Approach 1:
The complex calculation logic and control algorithms are extracted from the user interface and embedded within the pump's processor. Users only need to input simple parameters (total volume, duration), while the pump automatically handles all precise rate calculations and step transitions, maintaining precision while simplifying operation.
Solution Approach 2:
The pump performs all complex programming and parameter calculation automatically based on minimal user input, serving itself to generate the precise infusion profile without requiring the user to understand or program the underlying complex control logic.

AI summary
Embodiments relate to systems, methods and devices for delivering a drug or other therapy to a patient with an ambulatory infusion pump configured to provide a series of tolerance-building steps leading up to a plateau delivery rate. The plateau delivery rate is maintained until the prescribed amount of drug or therapy fluid is delivered to the patient. Embodiments of the invention include providing the patient or other user with a mechanism to decrease, or step down, the therapy delivery rate if a tolerance was not achieved at a lower rate, and providing notifications prior to a step up in a dosage delivery rate.
