Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient fluid administration systems face challenges such as errors in fluid compatibility, incorrect dosages, and inappropriate medication sequences due to labeling mistakes and lack of real-time monitoring, which can lead to unsafe patient care.
Innovation Solution
A system comprising a fluid port with sensors and a flow controller that adjusts fluid flow based on characterized attributes of the fluid, using a rules engine to ensure compatibility and adherence to medical orders, patient-specific information, and clinical guidelines, thereby preventing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual fluid administration with labeling is used, then fluid delivery to patient is simple and direct, but errors in fluid compatibility, dosage, and sequence occur due to labeling mistakes and lack of monitoring
Solution Approach 1:
The patent introduces a flow control valve as an intermediary device between the fluid source and patient. This valve acts as a mediator that automatically controls fluid flow based on sensor feedback, eliminating the need for manual monitoring while ensuring patient safety. The valve receives control signals from the processor based on fluid attributes detected by sensors, thereby preventing errors without requiring complex continuous human intervention.
Solution Approach 2:
The system implements a feedback mechanism where sensors continuously monitor fluid attributes (such as composition, flow rate, or other characteristics) and provide this information to the processor. The processor then adjusts the flow control valve based on this feedback to ensure safe and appropriate fluid administration. This closed-loop feedback system automatically corrects potential errors in fluid compatibility and dosage.
2Reliability
If sensors and flow control valves are added to monitor and control fluid flow, then fluid administration safety is improved, but device complexity and cost increase
Solution Approach 1:
The flow control valve serves multiple functions: it controls fluid flow rate, responds to sensor feedback, and can be adjusted by the processor based on various fluid attributes. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while maintaining high fluid administration accuracy.
Solution Approach 2:
The system is designed to be self-regulating through the integration of sensors, processor, and flow control valve. Once configured, the system automatically monitors fluid attributes and adjusts flow without requiring continuous external intervention. This self-service capability reduces the operational complexity despite the increased number of components.
3Reliability
If real-time sensor monitoring and automated flow control are implemented, then medication errors are prevented, but ease of operation is reduced due to automated control mechanisms
Solution Approach 1:
The system performs preliminary actions by pre-configuring the flow control valve and sensors before fluid administration begins. The processor is pre-programmed with the necessary control logic and safety parameters. This preliminary setup allows the system to automatically prevent errors during operation without requiring complex real-time manual adjustments, thereby maintaining ease of operation while ensuring reliability.
