Multi-Parameter Infusion Controller for Automated Medication Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During surgery, it is challenging to identify patients who benefit from volume loading, vasoactive, or inotropic agents to manage hypotension effectively, as current methods rely on single parameter measurements and lack automated systems for controlling fluid and medication administration, leading to difficulties in maintaining blood pressure and preventing organ failure.
Innovation Solution
A device with multiple actuators for administering medications, sensors for measuring multiple parameters, and a controller that considers dependencies between medications to automatically adjust their administration, allowing for complex interactions and optimal dosing based on real-time patient data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple medicaments are administered based on single parameter measurements, then medication administration can be simplified, but the accuracy of identifying patients who benefit from specific treatments decreases
Solution Approach 1:
The patent transitions from single-parameter decision-making to multi-parameter evaluation by measuring at least two parameters (e.g., cardiac output, systemic vascular resistance, blood pressure) and using their combinations to determine medicament administration. This dimensional expansion enables more accurate patient stratification while maintaining operational simplicity through automated controller decisions.
2Reliability
If automated control of fluid and medication administration is implemented, then the duration of hypotension can be minimized and organ failure prevented, but the device complexity increases
Solution Approach 1:
The patent combines multiple measurement functions (cardiac output monitoring, blood pressure measurement, systemic vascular resistance calculation) and multiple medication delivery functions into a single integrated device with a unified controller. This merging reduces the need for separate devices and manual coordination, achieving reliable automated control while managing complexity through integration.
Solution Approach 2:
The controller continuously monitors measured parameters and automatically adjusts medicament administration based on real-time patient status. This closed-loop feedback system ensures reliable blood pressure maintenance by dynamically responding to physiological changes, while the automated nature of the feedback reduces the complexity burden on operators.
3Manufacturing precision
If dependencies between medicaments are considered in the control algorithm, then optimal dosing can be achieved, but the complexity of the control algorithm increases
Solution Approach 1:
The controller is pre-programmed with knowledge of medicament interactions and dependency relationships before patient treatment begins. This preliminary configuration allows the system to automatically consider these dependencies during treatment without requiring complex real-time calculations, achieving precise dosing while managing algorithmic complexity through advance preparation.
