Solution Overview
Problem
Existing infusion pump systems primarily focus on the main active ingredients when calculating dosage and delivery rates, neglecting the comprehensive consideration of multiple drug solution components and their parameters, which is inadequate for complex medical treatments involving multiple drugs and artificial nutrition.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing infusion pump systems only consider main active ingredients when calculating dosage and delivery rates, then the system complexity is reduced and operation is simplified, but the precision and comprehensiveness of dosage calculation deteriorates for complex multi-drug treatments
Solution Approach 1:
The system segments the drug solution into multiple components (main active ingredient, other active ingredients, additives, preservatives, carriers) and tracks each component's parameters separately. The control unit stores and processes parameters for each component individually, then integrates them for comprehensive dosage calculation, thereby achieving precise multi-drug dosage without overwhelming system complexity.
Solution Approach 2:
The system performs preliminary action by pre-storing parameters and ingredients of all drug solution components in the control unit's memory before actual infusion. This preliminary data preparation enables the control unit to automatically retrieve and process all necessary parameters during dosage calculation, eliminating manual conversion errors and ensuring comprehensive consideration of all components.
2Ease of operation
If infusion pumps automatically convert dosage units to delivery rates using barcode scanning, then the ease of operation is improved and arithmetic errors are reduced, but the comprehensiveness of parameter consideration deteriorates as only main active ingredients are taken into account
Solution Approach 1:
The control unit is designed with multi-functionality to handle both barcode scanning for main active ingredient identification and comprehensive parameter storage for all solution components. It can retrieve parameters from barcode data while also accessing pre-stored information about other ingredients, additives, and carriers, thereby maintaining ease of operation while preventing information loss about minor components.
Solution Approach 2:
The control unit acts as an intermediary between the barcode scanner (which provides main active ingredient information) and the dosage calculation process. It mediates by supplementing barcode data with additional parameter information about other solution components stored in its memory, ensuring that the automated conversion process considers all ingredients without requiring manual input.
3Reliability
If only main active ingredients are considered in dosage calculations, then the device complexity and calculation time are reduced, but the reliability of treatment coordination deteriorates for patients receiving multiple drugs with interacting effects
Solution Approach 1:
The system segments the drug solution into multiple components (main active ingredient, other active ingredients, additives, preservatives, carriers) and tracks each component's parameters separately. The control unit stores and processes parameters for each component individually, then integrates them for comprehensive dosage calculation, thereby achieving precise multi-drug dosage without overwhelming system complexity.
Solution Approach 2:
The system implements feedback by continuously monitoring the actual delivery rates of all pump devices and comparing them against the calculated target values that consider all drug components. The control unit can detect deviations and issue alarm signals or adjust delivery rates to maintain reliable treatment coordination, ensuring that interactions between multiple drugs are properly managed.
